The Genocidal Healer

By James White

Chapter 1

THEY had assembled in a temporarily unused compartment on the hospital's eighty-seventh level. The room had seen service at various times as an observation ward for the birdlike Nallajims of physiological classification LSVO, as a Melfan ELNT operating theater, and, most recently, as an overflow ward for the chlorine-breathing Illensan PVSJs, whose noxious atmosphere still lingered in trace quantities. For the first and only time it was the venue of a military court and, Lioren thought hopefully, it would be used to terminate rather than extend life.

Three high-ranking Monitor Corps officers had taken their seats facing a multispecies audience that might be sympathetic, antagonistic, or simply curious. The most senior was an Earth-human DBDG, who opened the proceedings.

"I am Fleet Commander Dermod, the president of this specially convened court-martial," it said in the direction of the recorder. Then, inclining its head to one side and then the other, it went on. "Advising me are the Earth-human Colonel Skemp-ton of this hospital, and the Nidian, Lieutenant-Colonel Dragh-Nin, of the Corps's other-species legal department. We are here at the behest of Surgeon-Captain Lioren, a Tarlan BRLH, who is dissatisfied with the verdict of a previous Federation civil-court hearing of its case. The Surgeon-Captain is insisting on its right as a serving officer to be tried by a Monitor Corps military tribunal.

"The charge is gross professional negligence leading to the deaths of a large but unspecified number of patients while under its care."

Without taking its attention from the body of the court, and seeming deliberately to avoid looking at the accused, the fleet commander paused briefly. The rows of chairs, cradles, and other support structures suited to the physiological requirements of the audience held many beings who were familiar to Lioren: Thornnastor, the Tralthan Diagnostician-in-Charge of Pathology; the Nidian Senior Tutor, Cresk-Sar; and the recently appointed Earth-human Diagnostician-in-Charge of Surgery, Conway. Some of them would be willing and anxious to speak in Lioren's defense, but how many would be as willing to accuse, condemn, and punish?

"As is customary in these cases," Fleet Commander Der-mod resumed gravely, "the counsel for the defense will open and the prosecution will have the last word, followed by the consultation and the agreed verdict and sentence of the officers of this court. Appearing for the defense is the Monitor Corps Earth-human, Major O'Mara, who has been Chief of the Department of Other-Species Psychology at this hospital since it first became operational, assisted by the Sommaradvan, Cha Thrat, a member of the same department. The accused, Surgeon-Captain Lioren, is acting for and is prosecuting itself.

"Major O'Mara, you may begin."

While Dermod had been speaking, O'Mara, whose two eyes were recessed and partially hidden by thin flaps of skin and shadowed by the gray hair which grew in two thick crescents above them, had looked steadily at Lioren. When it rose onto its two feet, the prompt screen remained unlit. Plainly the Chief Psychologist intended speaking without notes.

In the angry and impatient manner of an entity unused to the necessity for being polite, it said, "May it please the court, Surgeon-Captain Lioren stands accused, or more accurately stands self-accused, of a crime of which it has already been exonerated by its own civil judiciary. With respect, sir, the accused should not be here, we should not be here, and this trial should not be taking place."

"That civil court," Lioren said harshly, "was influenced by a very able defender to show me sympathy and sentiment when what I needed was justice. Here it is my hope that—"

"I will not be as able a defender?" O'Mara asked.

"I know you will be an able defender!" Lioren said loudly, knowing that the process of translation was removing much of the emotional content from the words. "That is my greatest concern. But why are you defending me? With your reputation and experience in other-species psychology, and the high stan- dards of professional behavior you demand, I expected you to understand and side with me instead of—"

"But I am on your side, dammit—" O'Mara began. He was silenced by the distinctively Earth-human and disgusting sound of the fleet commander clearing its main breathing passage.

"Let it be clearly understood," Dermod said in a quieter voice, "that all entities having business before this court will address their remarks to the presiding officer and not to each other. Surgeon-Captain Lioren, you will have the opportunity to argue your case without interruption when your present defender, be he able or inept, has completed his submission. Continue, Major."

Lioren directed one eye toward the officers of the court, another he kept on the silent crowd behind him, and a third he fixed unwaveringly upon the Earth-human O'Mara, who, still without benefit of notes, was describing in detail the accused's training, career, and major professional accomplishments during his stay at Sector Twelve General Hospital. Major O'Mara had never used such words of praise to or about Lioren in the past, but now the things it was saying would not have been out of place in a eulogy spoken over the mortal remains of the respected dead. Regrettably, Lioren was neither dead nor respected.

As the hospital's Chief Psychologist, O'Mara's principal concern was and always had been the smooth and efficient operation of the ten-thousand-odd members of the medical and maintenance staff. For administrative reasons, the entity O'Mara carried the rank of major in the Monitor Corps, the Federation's executive and law-enforcement arm, which was also charged with the responsibility for the supply and maintenance of Sector General. But keeping so many different and potentially antagonistic life-forms working together in harmony was a large job whose limits, like those of O'Mara's authority, were difficult to define.

Given even the highest qualities of tolerance and mutual respect among all levels of its personnel, and in spite of the careful psychological screening they underwent before being accepted for training in the Galactic Federation's most renowned mul-tienvironment hospital, there were still occasions when serious interpersonal friction threatened to occur because of ignorance or misunderstanding of other-species cultural mores, social behavior, or evolutionary imperatives. Or, more dangerously, a being might develop a xenophobic neurosis which, if left untreated, would ultimately affect its professional competence, mental stability, or both.

A Tralthan medic with a subconscious fear of the abhorrent little predators which had for so long infested its home planet might find itself unable to bring to bear on one of the physiologically similar, but highly civilized, Kreglinni the proper degree of clinical detachment necessary for its treatment. Neither would it feel comfortable working with or, in the event of personal accident or illness, being treated by a Kreglinni medical colleague. It was the responsibility of Chief Psychologist O'Mara to detect and eradicate such problems before they could become life- or sanity-threatening or, if all else failed, to remove the potentially troublesome individuals from the hospital.

There had been times, Lioren remembered, when this constant watch for signs of wrong, unhealthy, or intolerant thinking which the Chief Psychologist performed with such dedication made it the most feared, distrusted, and disliked entity in Sector General.

But now O'Mara seemed to be displaying the type of uncharacteristic behavior that it had always considered as a warning symptom in others. By defending this great and terrible crime of negligence against an entire planetary population, a piece of wrong thinking without precedent in Federation history, it was ignoring and reversing the professional habits and practices of a lifetime.

Lioren stared for a moment at the entity's head fur, which was a much lighter shade of gray than he remembered, and wondered whether the confusions of advancing age had caused it to succumb to one of the psychological ills from which it had tried so hard to protect everyone else. Its words, however, were reasoned and coherent.

". . . At no time was it suggested that Lioren was promoted beyond its level of competence," O'Mara was saying. "It is a Wearer of the Blue Cloak, the highest professional distinction that Tarla can bestow. Should the court wish it I can go into greater detail regarding its total dedication and ability as an other-species physician and surgeon, based on observations made during its time in this hospital. Documentation and personal affidavits provided by senior and junior Monitor Corps officers regarding its deservedly rapid promotion after it left us are also available. But that material would be repetitious and would simply reinforce the point that I have been making, that Lioren's professional behavior up to and, I submit, while committing the offense of which it is charged, was exemplary.

"I believe that the only fault that the court will find in the accused," O'Mara went on, "is that the professional standards it has set itself, and until the Cromsag Incident achieved, were unreasonably high and its subsequent feelings of guilt disproportionately great. Its only crime was that it demanded too much of itself when—"

' 'But there is no crime!'' O'Mara's assistant, Cha Thrat, broke in loudly. It rose suddenly to its full height. "On Sommaradva the rules governing medical practice for a warrior-surgeon are strict, stricter by far than those accepted on other worlds, so I fully understand and sympathize with the feelings of the accused. But it is nonsense to suggest that strict self-discipline and high standards of professional conduct are in any sense bad, or a crime, or even a venial offense."

"The majority of the Federation's planetary histories," O'Mara replied in an even louder voice, the deepening facial color showing its anger at this interruption from a subordinate, "contain many instances of fanatically good political leaders or religious zealots which suggest otherwise. Psychologically it is healthier to be strict in moderation and allow a little room for-"

' 'But surely,'' Cha Thrat broke in again,' 'that does not apply to the truly good. You seem to be arguing that good is ... is bad\"

Cha Thrat was the first entity that Lioren had seen of the Sommaradvan DCNF classification. Standing, it was half again as tall as O'Mara, and its arrangement of four ambulatory limbs, four waist-level heavy manipulators, and a further set for food provision and fine work encircling the neck gave it a shape that was pleasingly symmetrical and stable—unlike that of the Earth-humans, who always seemed to be on the point of falling on their faces. Of all the beings in the room, Lioren wondered if this entity would be the one who best understood his feelings. Then he concentrated his mind on the images coming from the eye that was watching the officers of the court.

Colonel Skempton was showing its teeth in the silent snarl w

Earth-humans gave when displaying amusement or friendship, the Nidian officer's features were unreadable behind their covering of facial fur, and the fleet commander's expression did not change at all when it spoke.

"Are the counsels for the defense arguing among themselves regarding the guilt or otherwise of the accused," it asked quietly, "or simply interrupting each other in their eagerness to expedite the case? In either event, please desist and address the court one at a time."

"My respected colleague," O'Mara said in a voice which, in spite of the emotion-filtering process of translation, sounded anything but respectful, "was speaking in support of the accused but was a trifle overeager. Our argument will be resolved, in private, at another time."

"Then proceed," the fleet commander said. Cha Thrat resumed its seat, and the Chief Psychologist, its face pigmentation still showing a deeper shade of pink, went on, "The point I am trying to make is that the accused, in spite of what it believes, is not totally responsible for what happened on Cromsag. To do so I shall have to reveal information normally restricted to my department. This material is—"

Fleet Commander Dermod was holding up one forelimb and hand, palm outward. It said, "If this material is privileged, Major, you cannot use it without permission from the entity concerned. If the accused forbids its use—" "I forbid its use," Lioren said firmly. "The court has no choice but to do the same," Dermod went on as if the Surgeon-Captain had not spoken. "Surely you are aware of this?''

"I am also aware, as, I believe, are you, sir," said O'Mara, "that if given the chance the accused would forbid me to say or do anything at all in its defense."

The fleet commander lowered its hand and said, "Nevertheless, where privileged information is concerned, the accused has that right."

"I dispute its right to commit judicial suicide," said O'Mara, "otherwise I would not have offered to defend an entity who is so highly intelligent, professionally competent, and completely stupid. The material in question is confidential and restricted but not, however, privileged since it was and is available to any accredited authority wishing for complete psychological data on a candidate before offering to employ it in a position of importance, or advancement to a level of greater responsibility. Without false modesty I would say that my department's psych profile on Surgeon-Captain Lioren was what gained its original commission in the Monitor Corps and probably its last three promotions. Even if we had been able to monitor closely the accused's psych profile following its departure from the hospital there is no certainty that the Cromsag tragedy could have been averted. The personality and motivations of the entity who caused it were already fully formed, stable, and well integrated. To my later regret I saw no reason to alter them in any way.''

The Chief Psychologist paused for a moment to look at the beings crowding the room before returning its attention to the officers of the court. Its desk screen came to life, but O'Mara barely glanced at the upward march of symbols as it continued speaking.

"This is the psych record of a being with a complete and quite remarkable degree of dedication to its profession," the major said. "In spite of the presence of fellow Tarlans of the female sex at that time, there are no social or sexual activities listed or, indeed, any indication that it wished to indulge in either. Self-imposed celibacy is undertaken by members of several intelligent species for various personal, philosophical, or religious reasons. Such behavior is rare, even unusual, but not unsane.

"Lioren's file contains no incidents, behavior, or thinking with which I could find fault," O'Mara went on. "It ate, slept, and worked. While its colleagues were off duty, relaxing or having fun, it spent its free time studying or acquiring extra experience in areas which it considered of special interest. When promotion came, it was intensely disliked by the subordinate medical and environmental maintenance staff on its ward because it demanded of them the same quality of work that it required of itself, but fortunate indeed were the patients who came under its care. Its intense dedication and inflexibility of mind, however, suggested that it might not be suitable for the ultimate promotion to Diagnostician.

"This was not the reason for it leaving Sector General," O'Mara said quickly. "Lioren considered many of the hospital staff to be lax in their personal behavior, irresponsible when off duty, and, by its standards, nonserious to a fault, and it wished to continue its work in an environment of stricter discipline. It fully deserved its Corps promotions, including the command of the rescue operation on Cromsag that ended in disaster."

The Chief Psychologist looked down at its desktop, but it was not seeing the prompt screen, because for some reason it had closed its eyes. Suddenly it looked up again.

"This is the psych profile of an entity who had no choice but to act as it did," O'Mara resumed, "so that its actions in the circumstances were proper. There was no carelessness on its part, no negligence, and therefore, I submit, no guilt. For it was only after the few survivors had been under observation here for two months that we were able to unravel the secondary endo-crinological effects of the disease Lioren had been treating. If any offense was committed, it was the minor one of impatience allied to Lioren's firm belief that its ship's medical facilities were equal to the task demanded of them.

"I have little more to say," the major continued, "except to suggest to the court that its punishment should be in proportion to the crime and not, as the accused believes and the prosecution will argue, the results of that crime. Catastrophic and horrifying though the results of the Surgeon-Captain's actions have been, the offense itself was a minor one and should be treated as such.'' While O'Mara had been speaking, Lioren's anger had risen to a level where it might no longer be controllable. Brown blotches were appearing all over his pale, yellow-green tegument, and both sets of outer lungs were tightly distended to shout a protest that would have been too loud for proper articulation and would probably have damaged the sound sensors of many of those present.

"The accused is becoming emotionally distressed," O'Mara said quickly, "so I shall be brief. I urge that the case against Surgeon-Captain Lioren be dismissed or, failing that, that the sentence be noncustodial. Ideally the accused should be confined to the limits of this hospital, where psychiatric assistance is available when required, and where its considerable professional talents will be available to our patients while it is—"

"No!" Lioren said, in a voice which made those closest to him wince and the translator squawk with sound overload. "I have sworn, solemnly and by Sedith and Wrethrin the Healers, to forgo the practice of my art for the rest of my worthless life.''

"Now that," O'Mara replied, not quite as loudly as Lioren, "would indeed be a crime. It would be a shameful and unforgivable waste of ability of which you would be inarguably guilty."

"Were I to live a hundred lifetimes," Lioren said harshly, "I could never save a fraction of the number of beings I caused to die."

"But you could try—" O'Mara began, and broke off as once again the fleet commander raised his hand for silence.

"Address your arguments to the court, not each other," Der-mod said, looking at them in turn. "I shall not warn you again. Major O'Mara, some time ago you stated that you had little more to say. May the court now assume that you have said it?"

The Chief Psychologist remained standing fora moment; then it said, "Yes, sir" and sat down.

"Very well," the fleet commander said. "The court will now hear the case for the prosecution. Surgeon-Captain Lioren, are you ready to proceed?''

Lioren's skin showed an increasing and irregular discoloration caused by the deep emotional distress that even the earliest and innocent memories evoked, but his surface air sacs had deflated so that he was able to speak quietly.

"I am ready."

Chapter 2

THE Cromsag system had been investigated by the Monitor Corps scout ship Tenelphi while engaged on a survey mission in Sector Nine, one of the embarrassing three-dimensional blanks which still appeared in the Federation's charts. The discovery of a system containing habitable planets was a pleasant break in the boring routine of counting and measuring the positions of a myriad of stars, and when they found one displaying all the indications of harboring intelligent indigenous life, their pleasure and excitement were intense.

The pleasure, however, was short-lived.

Because a scout ship with a complement of only four entities did not have the facilities to handle a first-contact situation, the regulations forbade a landing, so the crew had to content themselves with conducting a visual examination from close orbit while trying to establish the natives' level of technology by analyzing their communications frequencies and any other electromagnetic radiation emanating from the planet. As a result of their findings, Tenelphi remained in orbit while it recklessly squandered its power reserves on the ship's energy-hungry sub-space communicator on increasingly urgent distress messages to base.

The Monitor Corps's specialized other-species contact vessel, Descartes, which normally made the initial approach to newly discovered cultures, was already deeply involved on the planet of the Blind Ones, where communications had reached the stage where it was inadvisable to break off. But the situation on the new planet was not a problem of First Contact but of insuring that enough of the natives would survive to make any kind of contact possible.

The Emperor-class battleship Vespasian, which was more than capable of waging a major war although in this instance it was expected to end one, was hastily converted to disaster-relief mode and dispatched to the region. It was under the command of the Earth-human Colonel Williamson, but in all matters pertaining to relief operations on the surface it was the Tarlan subordinate, Surgeon-Captain Lioren, who had the rank and the sole responsibility.

Within an hour of the two vessels matching orbits, Tenelphi had docked with Vespasian and the scout ship's captain, the Earth-human Major Nelson, and its Nidian medical officer, Surgeon-Lieutenant Dracht-Yur, were in the operations room giving the latest situation report.

"We have recorded samples of their radio signals," Major Nelson reported briskly, "even though the volume of traffic is unusually small. But we were unable to make any sense of it because our computer is programmed for survey work with just enough reserve capacity to handle the translation requirements of my crew. As things stand, we don't even know if they know we are here—"

"Vespasian's tactical computer will translate the surface traf- fie from now on," Colonel Williamson broke in impatiently, "and the information will be passed to you. We are less interested in what you did not hear than in what you saw. Please go on, Major."

It was unnecessary to mention a fact known to everyone present, that while Williamson's tremendous capital ship had the bigger brain, Nelson's tiny and highly specialized survey vessel had eyes that were second to none.

"As you can see," Nelson went on, tapping the keys that threw the visuals onto the room's enormous tactical display screen, "we surveyed the planet from a distance of five diameters before moving in to map in more detail the areas that showed signs of habitation. It is the third planet, and so far as we know the only life-bearing one, of a system of eight planets. Its day is just over nineteen hours long, surface gravity one and one-quarter Earth-normal, the atmospheric pressure in proportion, and its composition would not seriously inconvenience the majority of our warm-blooded oxygen-breathers.

"The land surface is divided into seventeen large island continents. All but the two at the poles are habitable, but only the largest equatorial continent is presently inhabited. The others show signs of habitation in the past, together with a fairly high level of technology that included powered surface and air transport, with radiation traces suggesting that they had fission-assisted electricity generation. Their towns and cities now appear to be abandoned and derelict. The buildings are undamaged, but there are no indications of industrial or domestic wastes either in atmosphere or on the ground, no evidence of food cultivation, and the road surfaces, street paving, and a few of the smaller buildings have been broken up and damaged due to the unchecked growth of plant life. Even in the inhabited areas of the equatorial continent there is similar evidence of structural and agrarian neglect with the associated indications of—"

"Obviously a plague," Lioren said suddenly, "an epidemic for which they have little natural immunity. It has reduced the planetary population to the extent that they can no longer fully maintain all their cities and services, and the survivors have collected in the warmer and less power-hungry cities of the equator to—"

"To fight a bloody war!" the scout ship's medic, Dracht-Yur, broke in, its snarling Nidian speech making an angry accom- paniment to the emotionless translated words. "But it is a strange, archaic form of warfare. Either they love war, or hate each other, very much. Yet they seem to have an inordinate respect for property. They don't use mass-destruction weapons on each other; there is no evidence of aerial bombing or artillery, even though they still have large numbers of ground and atmosphere vehicles. They just use them to transport the combatants to the battleground, where they fight at close quarters, hand to hand and apparently without weapons. It is savage. Look!"

Vespasian's, tactical screen was displaying a series of aerial photographs of tropical forest clearings and city streets, sharp and clear despite massive enlargement and the fact that they had been taken from a vertical distance of fifty miles. Normally it was difficult to obtain much information on the body mass and physiological details of a native life-form from orbit—although a study of the shadow it cast could be helpful—but, Lioren thought grimly, far too many of these creatures had been obliging enough to lie flat on the ground dead.

The pictures shocked but did not sicken the Surgeon-Captain as they did Dracht-Yur, because the Nidian medic belonged to one of those strange cultures who reverenced the decomposing remains of their dead. Even so, the number of recently and not so recently dead lying about in the streets and forest clearings was bound to pose a health risk.

Lioren wondered suddenly whether the surviving combatants were unwilling or simply unable to bury them. A less sharp moving picture showed two of the creatures fighting together on the ground, and so gentle were the blows and bites they inflicted on each other that they might have been indulging publicly in a sexual coupling.

The Nidian seemed to be reading Lioren's mind, because it went on. "Those two look as if they are incapable of seriously damaging each other, and at first I assumed this to be a species lacking in physical endurance. Then other entities were seen who fought strongly and continuously for an entire day. But you will also observe that the bodies of these two show widespread patches of discoloration, while a few of the others have skins without blemish. There is a definite correlation between the degree of physical weakness and the area of discoloration on the body. I think it is safe to assume that these two are seriously ill rather than tired.

"But that," Dracht-Yur ended in an angry growl, "doesn't stop them from trying to kill each other."

Lioren raised one hand slightly from the tabletop, middle digits extended in the Tarlan sign of respect and approval. But the two officers gave no indication of understanding the significance of the gesture, which meant that they had to be complimented verbally.

"Major Nelson, Surgeon-Lieutenant Dracht-Yur," Lioren said, "you have both done very well. But there is more that you must do. Can I assume that the other members of your crew have also had the opportunity of observing the situation below and have discussed it among themselves?''

"There was no way of stopping them—" Nelson began. " Yes," Dracht-Yur barked.

"Good," Lioren said. "Tenelphi is detached from its current survey duty. Transfer its officers to Vespasian. They will join the crews of the first four reconnaissance vehicles to go down as advisors since they know more, perhaps only a little more, about the local situation than we do. This ship will remain in orbit until the most effective rescue site has been chosen ..."

At times like these Lioren was reluctant to waste time on politeness, but he had learned that, where Earth-human senior officers in particular were concerned, time wasted now would help expedite matters later. And Colonel Williamson was, after all, Vespasian's commander and nominally the senior officer.

"If you have any comments or objections so far, sir," Lioren said, "I would be pleased to hear them."

Colonel Williamson looked at Nelson and Dracht-Yur briefly before returning its attention to Lioren. The scout-ship officers were showing their teeth, and a few of the colonel's were also visible as it said, "Tenelphi will not be able to resume its survey mission until we have topped up its consumables, and I would be surprised if its officers objected to any break in that deadly dull routine. You are making friends, Surgeon-Captain. Please continue."

"The first priority is to end the fighting," Lioren said, "and only then will it be possible to treat the sick and injured. This forced cessation of hostilities will have to be achieved without inflicting additional casualties or causing too much mental dis- tress among the population. To a culture at the prespaceflight level of technology, the sudden arrival among them of a vessel of the size and power of Vespasian, and the visually monstrous entities it contains, would not be reassuring. The first approach will have to be made in a small ship by people who, for psychological reasons, must be of equal or lesser body mass than they are. And it will have to be done covertly, in an isolated area where there are few natives or, ideally, only one whose temporary withdrawal from among its friends will arouse minimum distress ..."

The vehicle chosen for the mission was Vespasian's short-range communications vessel, which was equally capable of space operations or extended aerodynamic maneuvering in atmosphere. It was small but comfortably appointed, Lioren thought, if one happened to be an Earth-human, but at present it was overloaded and overcrowded.

They descended steeply out of the orange light of sunrise into an uneven blanket of dark, predawn cloud, thrusters shut down and velocity reduced so that they would not cause unnecessary distress by dragging a sonic shock wave in their wake, and the ship was darkened except for the radiation from its infrared sensors, which the natives might or might not be able to see.

Lioren stared at the enhanced picture of the forest clearing with its single, low-roofed dwelling and outbuildings rushing up at them. Without power their ship was gliding in too steeply and much too fast and with the flight characteristics, it seemed, of an aerodynamically clean lump of rock. Then three small areas of vegetation were flattened suddenly and driven downward into shallow craters as the ship's pressor beams reached out to support it on immaterial, shock-absorbing stilts. The touchdown was silent and sudden but very gentle.

Lioren turned a disapproving eye toward the pilot, wondering, not for the first time, why some experts felt it necessary to display their expertise so dramatically; the boarding ramp slid out before he could think of words that were both complimentary and critical.

They wore heavy-duty space suits with the air tanks and helmet visors removed, confident that this makeshift body armor would protect them against any bare-handed attack by an intelligent life-form that used only natural weapons. The five Earth-humans and three Orligians in the party ran to search the outbuildings while Dracht-Yur and Lioren moved quickly toward the house, which, in spite of the early hour, had its internal lighting switched on. They circled the house once, keeping below the level of the closed and uncurtained windows, to stop at the building's only entrance.

Dracht-Yur focused its scanner on the door mechanism and the life-sensor on the spaces beyond; then it used the suit radio to say quietly, "Beyond the door there is a large room, presently unoccupied, and three smaller compartments opening off it. The first is empty of life, the second contains traces which are not moving and positioned so closely together that I can't be sure whether there are two or three entities, who are making the low, untranslatable noises characteristic of sleep. Maybe they are sick or wounded. The third room contains one being whose movements appear slow and deliberate, and the sounds from that compartment are quiet but distinct, like the intermittent contact between cooking utensils. The overall indication is that the occupants are unaware of our presence.

"The door mechanism is very basic," the Nidian medic continued, "and the large metal bar on the inside has not been engaged. You can simply lift the latch and walk in, sir."

Lioren was relieved. Breaking down the door would have made the job of convincing these people of his good intentions much more difficult. But with anything up to four natives in the house and only one overeager but diminuitive Nidian in support, Lioren was unwilling to enter just then. He remained silent until the others arrived to report that the outhouses contained only agricultural implements and nonsapient farm animals.

Quickly he described the layout of the house, then went on. "The greatest risk to us is the group of three or four beings occupying the room directly opposite this entrance, and they must not be allowed to leave it until the situation has been explained to them. Four of you guard the interior door and four the window in case they try to escape that way. Dracht-Yur and myself will talk to the other one. And remember, be quiet, careful, and nonaggressive at all times. Do not damage furniture or artifacts, and especially not the beings themselves, or do anything to suggest that we are not their friends."

He unlatched the door quietly and led the way inside.

An oil-burning lamp hung from the center of the ceiling, illuminating walls hung with a few pictorial carvings and what seemed to be displays of dried, aromatic vegetation, although to his Tarlan olfactory sensors the aroma was anything but pleasant. Against the facing wall there was a long dining bench with four high-backed chairs pushed under it. A few smaller tables and larger, more heavily padded chairs were visible, plus a large bookcase and other items which he could not immediately identify. The majority of the furniture was of wood and strongly but not expertly built, and a few of the items showed signs of being mass-produced. Plainly they were the very old, scratched, and dented legacies of better times. The middle of the room was uncluttered and covered only by a thick carpet of some fabric or vegetable material that deadened the sound of their feet as they crossed it.

All three of the internal doors had been left ajar, and from the room occupied by the single native the quiet noises of cooking utensils making contact with crockery were accompanied by a soft, wailing sound that was untranslatable. Lioren wondered if the entity was in pain from illness or wounds, or was perhaps indulging in its version of mouth music. He was about to move in to confront the native when Dracht-Yur grasped one of his medial hands and pointed toward the door of the other occupied room.

One of the Earth-humans had been gripping the door mechanism tightly to prevent it being opened from within. Now it held out its free hand waist high with three digits extended, then lowered it palm downward to show two digits at hip level, and brought it down almost to its knee joint before showing one digit. For an instant it released the door handle, pressed both palms together and brought its hands to one side of its face, then inclined its head and closed both of its eyes.

For a moment Lioren was completely baffled by the gestures until he remembered that the Earth-human DBDG classification, and quite a few other life-forms, adopted this peculiar position while asleep. The rest of the hand signals could only mean that the room contained three children, one of whom was little more than an infant, and that they were all asleep.

Lioren dipped his head Earth-human fashion in acknowledgment, relieved that the children could be easily contained in their room so that there would be no possibility of uninformed and terrified escapees spreading panic throughout the area. Feeling pleased and much more confident, he moved forward to open communication with what, judging by the sounds emanating from the food-preparation room, was almost certainly the only adult in the house.

The entity had its back turned toward the entrance, showing him a three-quarters rear profile as it busied itself with some task that was concealed by its upper torso. Because of the absence of individually mobile eye mountings in its cranium and the consequent loss of all-around vision, Lioren was able to watch it for a moment without it being able to see him.

Its bodily configuration more closely resembled Lioren's own than those of the Earth-humans, Nidians, or Orligians accompanying him, which should greatly reduce the visual shock of first contact. Except for the possession of three sets of limbs-two ambulators, two medial heavy manipulators, and two more at neck level for eating and to perform more delicate work, rather than the Tarlan's three sets of four—and a cranium covered by thick, blue fur that continued in a narrow strip along the spine to the vestigial tail, the general physical characteristics were remarkably similar. Its skin showed areas of pale yellow-discoloration that were symptomatic of the plague that, with the savage and barbaric war, was threatening to sweep its planet free of intelligent life. The creature's physiological classification was DCSL, and curing its medical condition, at least, would be relatively simple once he obtained its cooperation.

Gently at first but with increasing firmness Lioren began clapping two of his guantleted, medial hands together to attract its attention, and when it swung around suddenly to face him, Lioren said, "We are friends. We have come to—"

It had been supporting a large bowl partially filled with a pale gray semiliquid material between its body and one medial hand, while the other medial hand was holding and pouring the contents of a smaller bowl into the first. Both containers, Lioren had time to note, were thick-walled and seemed to be made of a hard but very brittle ceramic, as was proved by the way they shattered when dropped onto the floor. The noise was loud enough to waken the three youngsters in the other room, and one of them, probably the infant, began making loud, frightened sounds which did not translate.

"We will not harm you," Lioren began again. "We have come to help cure you of the terrible disease which—"

The creature made a high-pitched gobbling sound which translated as, "The children! What have you done to the children?" and hurled itself at Lioren and Dracht-Yur.

It was not a bare-handed attack.

From the number of kitchen implements lying on the tabletop nearby it had snatched up a knife, which it swung at Lioren's chest. The blade was long and pointed, serrated along one edge and sharp enough to leave a deep scratch in the fabric of Lioren's heavy-duty space suit. But the creature was a quick learner, because the second blow was a straight-armed jab which might have penetrated if Lioren had not grasped the creature's wrist in two medial hands and used a third to prise the weapon from its fingers, taking a small, incised wound to one of his own digits in the process, while at the same time holding off its two upper hands, which seemed intent on tearing holes in his face.

The violence of its attack sent Lioren staggering backward into the other room, and he had a glimpse of the diminutive Dracht-Yur diving at the creature's legs and wrapping its short, furry arms tightly around them. The creature overbalanced and all three of them crashed to the floor.

"What are you waiting for, immobilize it!" Lioren said sharply. Then with a sudden feeling of concern for the being, he said, "As yet I am unfamiliar with your internal physiology, and I trust that the weight of my body against your lower thorax is not causing damage to underlying organs."

The creature's response was to struggle even harder against the Earth-human, Orligian, and Tarlan hands holding it down, and only a few of the sounds it was making were translatable. Looking at the obviously confused and terrified being, Lioren spoke silent and highly critical words to himself. This, his first contact with a member of a newly discovered intelligent species, had not been handled well.

"We will not harm you," Lioren said, trying to sound reassuring in a voice louder than that of the creature and those of the three children in the other room, all of whom were awake and contributing their own untranslatable sounds. "We will not harm your children. Please calm yourself. Our only wish is to help you, all of you, to live out your lives free of war and the disease which is affecting you ..."

It must have understood his translated words, because it had grown silent as he was speaking, but its struggle to free itself continued.

"But if we are to find a cure for this disaster," Lioren went on in a quieter voice, "we will have to isolate and identify the pathogen within your body causing it, and to do this we require specimens of your blood and other body fluids ..."

They would also be needed to prepare large quantities of safe anesthetics, tranquilizing gases and synthetic food suited to the species metabolism if the war as well as the disease was to be checked with minimum delay and loss of life. But this did not seem to be the right moment to tell it all of the truth, because its efforts to break free had intensified.

Lioren looked at Dracht-Yur and indicated one of the native's medial arms where muscle tension and elevated blood pressure had caused one of the veins to distend, making it an ideal site for withdrawing blood samples.

"We will not harm you," Lioren repeated. "Do not be afraid. And please stop moving your arm."

But the large, glittering, and multibarreled instrument that the Nidian medic had produced, while absolutely painless in use, was not an object to inspire confidence. If their positions had been reversed, Lioren knew, he would not have believed a single word he was saying.

Chapter 3

WITH a few violent exceptions, the subsequent contacts with the planet's natives, whose name for their world was Cromsag, went more easily. This was because Vespasian's transmitter had matched frequencies with the Cromsaggar broadcast channels to explain in greater detail who the off-world strangers were, where they had come from, and why they were there. And when the great capital ship landed and began to disgorge and erect prefabricated hospitals and food-distribution centers for the war's survivors, the verbal reassurances were given form and substance and all hostility against the strangers ceased.

But that did not mean that they became friends.

Lioren was sure that he knew everything about the Cromsag-gar, with the exception of how their minds worked. From recently dead cadavers abandoned in the war zones he had obtained a complete and accurate picture of their physiology and metabolism. This had enabled their injuries to be treated with safe medication and their war to be ended ingloriously under blankets of anesthetic gas. The scout ship Tenelphi had been pressed into service as a fast courier vessel plying between Cromsag and Sector General. It carried specimens requiring more detailed study in one direction and the findings of Head of Pathology Thornnastor, which more often than not agreed with Lioren's own, in the other.

But the Cromsaggar disease was proving difficult for even Diagnostician Thornnastor to isolate and identify. Living rather than dead specimens were required for study, if possible displaying the symptomology from onset to the preterminal stage of the condition, and Rhabwar, the hospital's special ambulance ship, was dispatched to obtain them. And even more baffling than the plague, to which the victims invariably succumbed before reaching middle age, was their mental approach to it.

One plague victim had agreed to talk to Lioren about itself, but its words had merely added to the Surgeon-Captain's confusion. He knew the patient only by its case file number, because the Cromsaggar considered their written and spoken symbol of identity to be the most important of personal possessions, and even though this one was close to termination it would not divulge its name to a stranger. When Lioren asked it why many of the Cromsaggar had attacked off-worlders with any weapon that came to hand, but fought among themselves only with teeth, hands and feet, it said that there was no honor or gain in killing a member of one's own race unless it was with great effort and extreme personal danger. For the same reason they always stopped short of killing a very sick, severely weakened, or dying adversary.

Taking the life of another intelligent entity, Lioren firmly believed, was the most dishonorable act imaginable. In his position he should respect the beliefs of others, regardless of how strange or shocking they might be to one of his strict Tarlan upbringing, but he could not and would not respect this one.

Changing the subject quickly, he asked, "Why is it that after you fight, the injured are taken away to be cared for while the dead remain untouched where they fall? We know that your people have some knowledge of medicine and healing, so why do you allow the dead to remain unburied, to risk the spread of further pestilence into your already plague-ridden population? Why do you expose yourselves to this totally unnecessary danger?"

The ravages of the disease, which had covered the entire epidermis in patches of livid camouflage, had left the patient very weak, and for a moment Lioren wondered if it was able to reply, or even if it had heard the questions. But suddenly it said, "A decomposing corpse is indeed a fearful risk to the health of those who pass nearby. The danger and the fear are necessary."

"But why?" Lioren asked again. "What do you gain by deliberately subjecting yourselves to fear and pain and danger?''

"We gain strength," the Cromsaggar said. "For a time, for a very short time, we feel strong again."

"In a very short time," Lioren said with the confidence of a healer backed by all the resources of Federation medical science, "we will make you feel well and strong without the fighting. Surely you would prefer to live on a world free of war and disease?''

From somewhere within its wasted body the patient seemed to gather strength. It said loudly, "Never in the memories of those alive, or in the memories of their ancestors, has there been a time without war and disease. The stories told of such times, when the planetwide ruins of towns and cities were populated by healthy and happy Cromsaggar, are stories told only to comfort small and hungry children, children who soon grow large enough to fight and to disbelieve these stories.

"You should leave us, stranger, to survive as we have always survived," it went on, straining to raise itself from the litter. "The thought of a world without war is too frightening to contemplate."

He asked more questions, but the patient, although fully conscious and displaying a slight improvement in its clinical condition, would not speak to him.

There was no doubt in Lioren's mind that a medical cure would quickly be discovered for the condition affecting the ten thousand-odd surviving Cromsaggar. But he was less sure whether a species which fought wars using only the natural weapons provided by evolution, because that made them feel good for a while, was worth saving. The strict rules of engagement that governed the fighting did not make the situation any less barbaric. They did not fight weaker opponents or children or the very few who were advanced in years, but only because the element of personal risk, and presumably the emotional reward, was reduced. He was glad that his only responsibility was the return of the plague sufferers to bodily health and not the curing of what appeared to be the even more diseased minds inhabiting those bodies.

And yet there had been occasions when, in an effort to give his patients something other than their own distressing clinical condition to think about, he had tried to explain star travel and the Galactic Federation to them. He had described the bewildering variety of shapes and sizes that intelligent life could take, and tried to make them understand that they lived on one inhabited world of many hundreds. He found those frightening and inexplicable minds of theirs had displayed an agility and a level of intelligence, although not the degree of education and knowledge, that was almost the equal of his own.

At those times there had been a small and transient improvement in their clinical condition, and that had made Lioren wonder if their craving for the danger and emotional excitement of war and single combat might not someday be fulfilled by the many and even more difficult challenges of peace. But they refused, or perhaps were psychologically unable because of cultural conditioning, to divulge personal information about their social behavior, moral strictures, or feelings on any subject unless, as in the present case, the patient was gravely ill and its mental resistance low.

The truth was that Lioren did not know how his patients felt, about themselves or anyone or anything else, and the stock question of the attending physician, "How do you feel?," was never answered.

Rhabwar was due in two days' time, and he decided that this particular patient would be among those transferred to the ambulance ship for investigation and treatment at Sector General, and that he would ask for a consultation with the vessel's senior medical officer.

Doctor Prilicla was a Cinrusskin, and, as a member of the Federation's only empathic species, it knew how everyone felt.

Lioren asked that the meeting take place on Rhabwar'?, casualty deck, rather than summoning Prilicla to the overcrowded sick bay of Vespasian, for reasons both practical and personal. The level of background emotional radiation from patients was much higher on Vespasian and would doubtless have distressed his visitor—it did no harm to show consideration to a professional colleague. On the ambulance ship there was less likelihood of his uncertainties regarding the Cromsaggar becoming known to his subordinates. It was his firm belief that a leader should display certainty at all times to the led if he was to receive their respect and total obedience.

Perhaps the empath held the same belief, but it was more likely that Prilicla had detected Lioren's emotional radiation at a distance, correctly analyzed it, and insured that their meeting would be private. He was grateful but not surprised. It was in the other's own selfish interest to minimize the generation of unpleasant emotional radiation around it, because to do otherwise would be to expose itself to exactly the same degree of unpleasantness.

The Cinrusskin positioned itself at eye level above one of the treatment tables, an enormous, incredibly fragile flying insect rendered small only by Lioren's greater body mass. From its tubular, exoskeletal body there projected six pencil-thin legs, four even more delicately fashioned manipulators, and four sets of wide, iridescent, and almost transparent wings that were beating slowly as, with the aid of the gravity nullifiers strapped'to its body, it maintained a stable hover. Only on Cinruss, with its thick atmosphere and gravitational pull of one-eighth standard G, could a species of flying insect have evolved intelligence, civilization, and star travel, and Lioren knew of no race within the Federation who did not consider them to be the most beautiful of all intelligent life-forms.

From one of the narrow openings in the delicate, convoluted eggshell that was its head came a series of musical trills and clicks which translated as "Thank you, friend Lioren, for the complimentary feelings you are harboring, and for the pleasure of meeting you in person for the first time. I also detect strong emotional radiation which suggests that the purpose of our meeting is professional and urgent rather than social.

"I am an empath, not a telepath," it ended gently. "You will have to tell me what is troubling you, friend Lioren."

Lioren felt sudden irritation at the other's continuing use of the word "friend." He was, after all, the medical and administrative director of the disaster relief operation on Cromsag, and a Surgeon-Captain in the Monitor Corps, while Prilicla was a civilian Senior Physician at Sector General. His irritation was making the empath's whole body tremble and causing its hovering flight to become less stable. He suddenly realized that he was attacking a being with a weapon, his feelings, against which it had no defense.

Even the pathologically warlike Cromsaggar would scorn to attack such a weak and defenseless enemy.

Lioren's irritation quickly changed to shame. This was a time to forget the feelings of justified pride in his high rank and in the many professional accomplishments that had earned it. Instead he should try, as he had often done in the past, to make the most effective use of the abilities of a subordinate whose feelings were easily hurt, and to control his emotions.

"Thank you, friend Lioren, for the mental self-discipline you have just displayed," Prilicla said before he could speak. It settled like a feather onto the top of the examination table, no longer trembling, and added, "But I detect strong background emotional radiation that you are finding more difficult to control and that, I feel sure, concerns the Cromsaggar. My own feelings of concern over the situation here are strong, perhaps as strong as yours, and shared feelings about other persons or situations cause me lesser discomfort. So if there is some way that I can help you please do not hesitate to speak."

Lioren felt renewed irritation at being given permission to discuss the Cromsaggar when his only purpose in coming here had been to do so, but the feeling was faint and transient. As he began to speak, the Surgeon-Captain knew that he was briefly verbalizing his latest report, copied to his Monitor Corps superiors and to Prilicla itself, that Rhabwar would be carrying back to Thornnastor, but it was necessary that the empath be acquainted with the current position if it was to understand the importance of the later questions.

He described the continually expanding search that had brought back data fit only for industrial archeologists. There were no recent life signs. Many of the abandoned cities and mining and manufacturing complexes in the north and south temperate regions were many centuries old, and so well con- structed that only a moderate effort would be required to restore them because the mineral wealth of the planet was far from exhausted. But the effort had not been made because the race's energies had been directed into fighting, so much so that many of them no longer grew food or had the strength to forage for that which grew wild, and the population had contracted into one region so that they could continue fighting without having to travel far to do so.

"When we stopped the war," Lioren went on, "or rather, when our sleep bombs halted the hundreds of small gang and two-person conflicts, there was an estimated surviving population of just under ten thousand entities, a number which included all the adults, their young, and a few newly born infants. But recently they have begun dying at the rate of about one hundred every day.''

Prilicla had begun to tremble again. Lioren was unsure whether it was in response to his emotional radiation or its own reaction to the news of the increasing number of fatalities. He tried to make his mind as well as his voice calm and clinical as he continued.

"In spite of our supporting them with shelters, clothing, and synthetic nutrient, even going so far as to gather supplies of local food that they were too weak to harvest for themselves, the deaths continue. Adult fatalities are invariably due to the plague, sometimes expedited by the debilitating effect of war injuries, and the children succumb to other diseases for which we have no specifics as yet. The Cromsaggar accept our help and our food, but only their young appear grateful for it. They show no interest in what we are trying to do for them. I feel that the adults tolerate us as an additional and unwelcome burden that they can do nothing about. My own feeling is that they are disinterested in their own survival and want to be left alone to commit racial suicide in the bloodiest fashion possible, and there are times when I feel that such a warlike and individually violent race should not be restrained from doing so. I do not know what they themselves feel, about anything."

"And you would like me to use my empathic faculty," Prilicla asked, "to tell you what they feel?"

"Yes," Lioren said, with so much feeling that the Cinrusskin trembled for a moment. "I hoped that you, Doctor, might have detected urges, instincts, feelings about themselves, their off- spring, or their present situation. My ignorance regarding their thinking and motivations is total. I would like to be able to do or say something to them that, as with an emotionally disturbed entity about to jump from a high building, would make them want to live instead of die. What is it that they fear, or need, that would make them want to survive?"

"Friend Lioren," Prilicla said without hesitation, "they fear death, like every other self-aware creature, and they want to survive. There were no indications, even in the most serious cases, of a wish for individual death or racial self-destruction, and they should not be—"

"I am sorry," Lioren broke in. "My earlier remark about allowing them to commit racial suicide—"

"They were words spoken because of helplessness and frustration, friend Lioren," Prilicla said, in the gentlest of interruptions, "that were completely contradicted by your underlying emotional radiation at the time. There was no need for an apology then or for your embarrassment now.

"And I had been about to say," it v/ent on, "that the Crom-saggar should not be criticized for their lack of cooperation, and the strong feelings of ingratitude until we know why they feel so ungrateful. These feelings were strongly present in all of the adult patients I monitored during transportation to Sector General and while I was present at the subsequent attempts to question them. They know we are trying to help them, but will not help us with clinical or personal information about themselves. When the interrogation was intensified they became agitated and fearful, and a marked if temporary remission of symptoms was observed at these times."

"I have made the same observation," Lioren said, "and assumed that it was the transfer of focus from a material condition to an immaterial one, the psychological mechanism which can sometimes make faith healing effective. I did not consider it an important datum."

"You are probably correct," Prilicla said. "But Chief Psychologist O'Mara is of the opinion that the marked remission due to the fear stimulus, combined with their fanatical refusal to communicate with us beyond the exchange of a few words, indicates the presence of an extremely strong and deep-rooted conditioning about which the Cromsaggar, as individuals, may be unaware. Friend O'Mara likens it to the racial group psycho- ses afflicting the Gogleskans, and says that it is trying to probe a very sensitive area that is surrounded by a very thick wall of mental scar tissue, and advises everyone concerned to proceed slowly and carefully.''

The Gogleskan psychosis forced them into avoiding direct physical contact with each other for the greater part of their adult lives, which was certainly not the problem with the Cromsaggar. Trying to control his feelings of impatience, Lioren said, "If we do not quickly find a cure for this plague, your Chief Psychologist will run out of subjects for his slow and careful investigation. What progress has been made since your last visit?"

"Friend Lioren," Prilicla said gently, "significant progress has been made. However, I sense and wholly agree with your need to avoid wasting time, so I suggest that Pathologist Mur-chison makes its report to you in person rather than having it relayed through myself, since you will doubtless have questions and I, because of my selfish need to surround myself with pleasant emotional radiation, have the unfortunate habit of accentuating the positive aspects of any situation."

Lioren's original reason for wanting a private meeting with Prilicla no longer seemed valid, and he could not reject the other's suggestion without seriously embarrassing both himself and the empath. He had the feeling, which was no doubt shared by the empath, that somehow he had lost the initiative.

Pathologist Murchison was a warm-blooded oxygen-breather of physiological classification DBDG with a body that, although considerably shorter and less massive than Lioren's own, had the soft, lumpy and top-heavy aspect of many of the Earth-human females. It was Thornnastor's principal assistant, when not required for special ambulance-ship duty, and its words were clear and concise and its manner respectful without being subservient. It also had the slightly irritating habit of answering questions before Lioren could ask them.

The identification, isolation, and neutralization of other-species pathogens, Pathologist Murchison said, was a routine procedure for Thornnastor's department, but the behavioral characteristics of the Cromsaggar virus—its mechanisms of transmission, infection, incubation, and propagation—remained undetectable to all of the normal investigative techniques. It was only in recent days, when the discovery had been made that the virus was either inherited at conception or transmitted by the mother prior to birth, that some progress had been made.

"The effects on the adult Cromsaggar are known to you," Murchison went on, "and the present indications are that every member of the species is infected. In the preterminal stage there is a livid rash and skin eruptions covering most of the body, accompanied by progressive and massive debilitation and lassitude which is sometimes overcome, temporarily, by strong emotional stimuli such as fear and danger. The effects on the children are less apparent and this led to the initial assumption that the young were immune, which they are not.

"We have since discovered," it continued, "that severe debility and lassitude are also present in the young, although it is difficult to be precise since we have no idea of how active a young, noninfected Cromsaggar should be. And, incredible though it might seem, neither can we be precise about the ages of these child patients. There is physiological and verbal evidence which suggests that many of them are not nearly as young as they appear, and that our age estimates should be extended by a factor of two or three because, in addition to its general debilitating effect, the plague retards the overall physiological development and greatly delays the onset of puberty. Probably there are psychological effects, as well, which might explain their grossly antisocial adult behavior, but again, this must remain speculative since you have yet to find a normal, disease-free Cromsaggar."

"I doubt whether such an entity exists," Lioren said. "But you spoke of having verbal as well as physiological evidence. These people absolutely refuse to give information about themselves. How was it obtained?"

"A large proportion of the cases you sent us were young or, as we now know, not yet physically mature," Murchison replied. "The adult patients remain completely uncooperative, but O'Mara was able to open dialogue with a few non-adults, who were much less reticent about themselves. Because of this immature viewpoint, adult motivations still remain unclear, and the picture of the Cromsaggar culture that is emerging is confusing and fraught with—"

"Pathologist Murchison," Lioren interrupted, "my interest is in the clinical rather than the cultural picture, so please confine yourself to that. My reason for asking Rhabwar to transfer so many young or not so young patients to the hospital was that they were among the large numbers left parentless or without adults to care for them. As well as suffering from undernourishment or exposure, conditions which are treatable, they displayed symptoms of respiratory distress associated with elevated temperature, or a wasting disease affecting the peripheral vascular and nervous systems. If Thornnastor's investigation into the plague is showing no results, what of these other and, I would think, clinically less complex conditions which seem to affect only the young?"

"Surgeon-Captain Lioren," the pathologist said, using Lioren's name and rank for the first time, "I did not say that no progress is being made.

"All of the non-adult cases are being investigated and significant progress is being made," it went on quickly. "In one of them, the condition presenting respiratory distress symptoms, there has been a minor but positive response to treatment. But the main effort is being directed toward finding a specific for the adult condition, because it has become evident that if the massive debilitation and growth-retarding effects of the plague were removed, the diseases currently afflicting the pre-adult Cromsaggar would be countered by their bodies' natural defense mechanisms and would no longer be life-threatening."

If that much was known, Lioren thought, then progress was indeed being made.

"The trials conducted so far," Murchison continued, "have been inconclusive. Initially the medication was introduced in trace quantities and the patients' condition monitored routinely for fifty standard hours before the dosage was increased, until on the ninth day, within a few moments of the injection being given, both patients lost consciousness."

It paused for a moment to look at Prilicla then, seeming to receive a signal undetectable by Lioren, resumed. "Both patients were placed in isolation some distance from the others and each other. This was done so as to minimize same-species interference in their emotional radiation. Doctor Prilicla reported that the level of unconsciousness was extraordinarily deep, but that there was no sign of the subconscious distress that would have been present had they been drifting into termination. It suggested that the unconsciousness might be recuperative since it had many of the characteristics of sleep following a lengthy period of physical stress and that nutrient should be given intravenously. A few days after this was done there was a minor remission of symptoms in both cases, and evidence of slight tissue regeneration, although both patients remained deeply unconscious and in a critical condition."

"Surely that means—!" Lioren began, and broke off as Mur-chison held up one hand as if it and not himself had the rank. But suddenly he was too excited to verbally tear its insubordinate head off as he should.

"It means, Surgeon-Captain," Murchison said, "that we must proceed very carefully and, if the first two test subjects regain consciousness rather than drifting into termination, we must closely monitor their clinical and psychological condition before the trial is extended to the other patients. Diagnostician Thornnastor and everyone in its department believes, and Doctor Prilicla feels sure, that we are on the way to finding the cure. But until we are certain we must exercise patience for a time until—"

"How much time?" Lioren demanded harshly.

Prilicla's fragile body was shaking as if a strong wind was blowing through the casualty deck, but Lioren could no more have controlled the emotional storm of impatience, eagerness, and excitement that raged within him than he could have flown on the empath's fragile wings. He would apologize to Prilicla later, but now all that he could think of was the steadily dwindling number of Cromsaggar who still clung to life on this plague world, and who might now have a chance to remain alive. More quietly, he asked, "How long must I wait?"

"I don't know, sir," the pathologist said. "I only know that Tenelphi has been ordered to remain at flight readiness at Sector General until the medication has been approved for general use, so as to bring you the first production batch without delay."

Chapter 4

RHABWAR departed with its casualty deck filled principally with non-adult Cromsaggar. There were many adult cases in Vespasian's sick bay—and in the widely dispersed medical stations that Lioren visited every day—who were in a much more serious condition, but the future survival of any species lay with its young, and those fortunate enough to be under the care of Thornnastor would be the first to be cured.

He ignored the polite but increasingly sarcastic messages from Colonel Skempton, the administrative head of Sector General, reminding him that the hospital was unable to accept the entire Cromsag population, depleted though it might be, for hospital-ization, and that they had already received more than enough members of that species for the purposes of clinical investigation. The entire Rhabwar crew would have been aware of Skempton's uncoded messages and the pressure on ward accommodation that had prompted them, but Prilicla had raised no objections to transporting the additional twenty patients.

Prilicla must be the least objectionable entity in the known galaxy, Lioren thought, unlike the Cromsaggar, who were his patients but who would never be his friends—unless there was a species-wide personality reconstruction by the Galactic Federation's many deities, of whose existence he had the gravest doubts.

Nevertheless, he spent all of his time, when he was not engaged in eating or sleeping, visiting the worst of his massively unlikable patients or encouraging the two hundred Corps medics and food technicians scattered across the continent who were trying, not always with success, to keep them alive. Always he hoped for a change of attitude, a willingness to talk to him and give information that would enable him to help them or that a tiny crack would show in their impenetrable wall of noncoop- eration, but in vain. The Cromsaggar, adult and young alike, continued dying at a steadily increasing rate because, like Sector General, he did not have the facilities to feed intravenously the entire population.

Occasionally, and in spite of the surface and orbital surveillance, they managed to die at each others' hands.

It had happened while he had been flying over one of the forest settlements that had long since been searched and declared empty of intelligent life, but that must have been because the occupants had taken to the trees to elude the searchers. Lioren spotted the small-scale war being waged by six of them in a grassy clearing between two buildings. By the time the flier, which would have carried a crew of four Nidians had it not been for his long Tarlan legs, had circled back to land and Dracht-Yur had helped him extricate himself from the tiny vessel's seating, the hand-to-hand fighting was over and four Cromsaggar lay still on the ground.

In spite of the numerous bites and digitally inflicted wounds covering the bodies, they were able to identify them as three dead males and one female whose life expectancy would be measured in seconds. Dracht-Yur pointed suddenly to the ground nearby where two separate trails of crushed and blood-spattered grass converged toward the open door of one of the buildings.

The advantage of a longer stride meant that Lioren went through the entrance seconds ahead of the Nidian, and his first sight of the two writhing, bloody bodies locked together in mortal combat on the floor reinforced the anger and disgust he felt at such animal behavior between supposedly intelligent beings. Moving forward, he quickly interposed his medial arms between the tightly pressed bodies and tried to push them apart. Only then did he make the disconcerting discovery that they were not, as he had first thought, two males fighting each other to the death but a male and female indulging in a sexual coupling.

Lioren released them and backed away quickly, but suddenly they broke apart and launched themselves at him just as Dracht-Yur arrived and blundered into his rear legs. The weight of the combined attack toppled him over backward so that he sprawled flat on the floor with the two Cromsaggar on top of him and the Nidian somewhere underneath. Within moments he was fighting for his life.

After the first few days on Cromsag had shown the natives to be too severely weakened by the plague to warrant the use of heavy protective suits, all Corps personnel had taken to wearing their cooler and less restrictive shipboard coveralls, which gave protection only against the sun, rain, and insect bites.

It was with a sense of outrage that Lioren realized that for the first time in his life the hands—not to mention the feet, knees, and teeth—of another person had been raised in anger against him. On Tarla disputes were not settled in this barbaric fashion. And even though the number of his limbs equaled the total of theirs, they did not behave like plague-weakened Cromsaggar. They were inflicting serious damage to his body and causing him more pain than he had ever thought it possible to feel.

As he fended off the more disabling body blows and tried desperately to keep the two Cromsaggar from pulling off his dirigible eye-supports, Lioren was aware of Dracht-Yur wriggling from underneath him and crawling toward the door. He was pleased when his attackers ignored it, because the Nidian's small, furry limbs had neither the muscle power nor the reach to make a useful contribution to the struggle. A few seconds later he caught a glimpse of the Nidian's head enclosed by a transparent envelope, heard the expected soft explosion of a bursting sleep-gas bulb, and felt the bodies of his attackers go suddenly limp and collapse on top of him before rolling slowly onto the floor.

For the few moments that the bodies, covered as they were by livid patches of discoloration and the oozing sores characteristic of preterminal plague victims, made heavy and almost intimate contact with him, it was a great relief to remember that one world's pathogens were ineffective against the members of off-planet species.

Designed as it was for maximum effect on the Cromsaggar metabolism, the anesthetic gas produced similar if less immediate results on other warm-blooded oxygen-breathers. Lioren was unable to move, but he was aware of the Nidian growling and barking urgently into its headset while it applied dressings to the worst of his wounds. Presumably it was telling the pilot of their flier to send for medical assistance, but his own translator pack had been damaged in the struggle and he could not understand a word. This did not worry him unduly, because the intense discomfort of his many injuries had faded to the mildest of irritations and the hard floor beneath him felt like the softest of sleeping pits. But his mind was clear and seemed unwilling to follow his body into sleep.

Interrupting the two Cromsaggar in the sex act had been a serious mistake, but an understandable one because none of his people had witnessed the occurrence of anything like a sexual coupling since arriving on Cromsag, and everyone, himself included, had assumed that the species had become too physically debilitated by the plague to make much of such activity possible. And their reaction, the sheer strength and ferocity of their attack, had surprised and shocked him.

During the very short breeding season on Tarla such activity, especially among the aging who had been lifemates for many years, was a cause for celebration and public display rather than a matter for concealment—although he knew that many species within the Federation, races who were otherwise highly intelligent and philosophically advanced, considered the mating process to be a private matter between the beings concerned.

Naturally, Lioren had no personal experience in this area, since his dedication to the healing arts precluded him indulging in any pleasure which would allow emotional factors to affect the clinical objectivity of his mind. If he had been an ordinary Tarlan male, an artisan or a member of one of the noncelibate professions interrupted in similar circumstances, there would have been a verbal impoliteness, but certainly not violence.

Distressing and distasteful as the incident had been, Lioren's mind would not rest in its search to find a reason for such an unreasonable reaction, however alien or uncivilized that reason might be. Could it be that, gravely ill and seriously injured as they had been in the fighting outside, they had crawled into the house to seek a moment of mutual pleasure together before dying? He knew that the coupling must have been by mutual agreement, because the Cromsaggar mechanics of reproduction were physiologically too complicated for the attentions of one partner to be forced on another.

That did not rule out the possibility that the coupling was the end result of the fighting, the bestowal of a female's favor on a warrior victorious in battle. There were many historical precedents for such behavior, although not, thankfully, in the history of Tarla. But that reason was unsatisfactory because both male and female Cromsaggar fought, although not each other.

Lioren made a mental note to prepare a detailed report of the incident for the cultural contact specialists who would ultimately have to produce a solution to the Cromsaggar problem, if any of the species survived and it was invited to join the Federation.

The four separate images of the room, including the one of Dracht-Yur working on the other casualties, that his immobilized eyes were still bringing him dimmed suddenly into blackness, and he remembered a feeling of mild irritation before he fell asleep in midthought.

Dracht-Yur confined him to the sick bay on Vespasian until the worst of his injuries healed, reminding him, as only a hairy, small-minded, and sarcastic dwarf of a Nidian could, that until then the relationship between them was one of doctor and patient and that in the present situation it was the Surgeon-Lieutenant who had the rank.

It could not, however, no matter how often it stressed the advisability of post-trauma rest and mental recuperation, bind Lioren's jaw closed or keep him from setting up a communication system by his bedside.

Time passed like a pregnant strulmer climbing uphill, and the medical situation on Cromsag worsened until the daily death rate climbed from one hundred to close on one-fifty, and still Tenelphi did not come. Lioren sent a necessarily brief hyper-space radio signal to Sector General, prerecorded and repeated many times so that its words could be reconstructed after fighting their way through the interference of the intervening stars, requesting news. He was not surprised when it was ignored, because the expenditure of power needed for a lengthy progress report would have been wasteful indeed. All that he was telling them was that he and the medical and support personnel on Cromsag were beginning to feel so helpless and angry and impatient that the condition verged on the psychotic, but the hospital probably knew that already.

Five days later he received a reply stating that Tenelphi had been dispatched and was estimating Cromsag in thirty-five hours. It was carrying medication, as yet incompletely tested for long-term effects, which was a specific against the grosser, more life-threatening symptoms of the plague, and that the details of the pathological investigation and directions for treatment accompanied the medication.

During the excitement that ensued Lioren went over his plans for fast distribution. Dracht-Yur relented to the extent of allowing him to transfer from sick bay to the communications center of Vespasian, but not to risk compounding his injuries by traveling the air or surface of Cromsag in vehicles totally unsuited to the Tarlan physiology. But the general feeling of relief and euphoria lasted only until the arrival of Tenelphi.

The scout ship carried more than enough of the antiplague specific, which required only a single, intravenous application, to treat every Cromsaggar on the planet, but Lioren was forbidden to use it until additional field trials had been carried out.

According to Chief Pathologist Thornnastor, the physiological results following a minimum dosage had been very good, but there were indications of possibly damaging side effects. Symptoms of mental confusion and periods of semiconscious-ness had been observed. These might prove to be temporary, but further investigation was required.

The single injection was followed by a slight but continuing reduction in symptoms, a slow improvement in the vital signs, and evidence of tissue and organs regeneration throughout the body in the days which ensued. During the periods of semicon-sciousness the test subjects had requested and consumed food in quantities which, considering stomach size and the clinical condition of the patients involved, seemed unusually large. There was a steady increase in body weight.

The non-adult subjects had responded in similar fashion, including the periods of unconsciousnessness interspersed with episodes of semiconsciousness and mental confusion, except that with the young the food demand in relation to their smaller size had been greater. Daily measurement had shown a steady increase in growth, both in body mass and limb dimensions.

It was thought probable that with the gradual remission of the condition the non-adult patients, whose physical growth had been retarded by the plague, were returning to optimum size for their ages. The periods of unconsciousness and impaired thinking were in response to a demand by the body for maximum rest during these periods of regeneration and were of little clinical importance. The medication was being used in minimum quantities, but a very small increase in the dosage of one test subject resulted in a strengthening and acceleration of the effects already noted. In spite of the excellent physiological results so far, the associated episodes of mental confusion were cause for concern lest a side effect of the medication led to long-term brain damage.

Thornnastor apologized for sending medication that it had not completely cleared for use, but said that Lioren's hyperspace radio signals had emphasized the urgency of the situation, and in order to save a few days' transit time between the medication's approval and its administration to the patients the final tests should be made concurrently on Cromsag and in Sector General.

"I have been instructed to conduct tests on a maximum of fifty Cromsaggar," Lioren said, when he was relaying Thorn-nastor's report to his senior medical officers. "The subjects are to include the widest possible variation in age and clinical condition, as well as minor variations in the dosage administered within that number. We are to pay particular attention to the mental state of these subjects during their periods of semiconsciousness, in the hope that their degree of confusion will be lessened when they are on their home world among others of their kind rather than in the strange and doubtless unsettling environment of Sector General. The initial test period will require ten days, followed by a further—"

"In ten days we would lose a quarter of the remaining population," Dracht-Yur broke in suddenly, its barking speech sounding angry even through the translator, "which has already shrunk to two-thirds of the number alive when Tenelphi found this Crutath-accursed planet. They're dying out there like, like . . ."

"That was my thought exactly," Lioren said, omitting the reprimand the Nidian deserved for its bad manners, and making a mental note to check on the meaning of the word "Crutath." "It is a thought which all of you share. But it is not because of our common feelings that I will disobey Thornnastor and ignore its recommendations. The decision is not yours. I will, of course, listen to your professional advice and accept it if it has merit, but the instruction to proceed and the responsibility for everything that ensues as a result will be entirely mine.

"This is what I am planning to do . . ."

There was no criticism of his plan because he had formulated it with great care and attention to detail, and—strangely, since it was coming from subordinates to a superior—the advice of- fered by many of them was personal rather than professional. They advised that he obey Thornnastor, but compromise by testing a few hundred, perhaps a thousand subjects instead of a mere fifty, saying that the course he was advocating would do nothing for any hopes he might have for future advancement. Lioren felt a strong temptation to do as they suggested, if only out of respect for the words of an entity said to be the foremost pathologist in the Federation rather than out of any selfish concern over his future career, but he was not sure that Diagnostician Thornnastor fully appreciated the urgency of the Cromsaggar problem. The hospital's Chief of Pathology was a perfectionist who would never allow imperfect work to leave its department, and giving Lioren permission to assist with the test program was probably the only compromise that it was capable of making. But a great, hulking Tralthan whose data-crammed mind, it was said, permanently accommodated the brain recordings of at least ten other-species medical authorities could be forgiven for a certain amount of mental confusion.

The Cromsaggar death rate was climbing steadily toward two hundred a day, and treating a mere fifty of them with an unnecessary degree of caution when virtually the entire population could be given the chance to live instead of dying in a lingering and painful manner was, to Lioren's mind, a great and a cowardly and a completely unacceptable wrong.

In this desperate situation he could accept imperfections even if Thornnastor's department could not. The psychological effects that accompanied the cure might be temporary, and even if they were not then they, too, might be curable in time. But if the worst should happen and permanent mental harm was the result, it was highly unlikely that the condition would be transmitted to an offspring, because O'Mara itself had stated that the damage was nonphysical. Any Cromsaggar child born of cured but mentally deficient parents would grow up healthy and sane.

Or as sane, Lioren thought, as it was possible for any member of this bloodthirsty race to be.

He had told his staff that it must be an operation combining maximum effort with maximum urgency, and that every single Cromsaggar on the planet must be treated for effect rather than submitting them to time-wasting trials, and within an hour of the meeting's end the plan was being implemented. On foot to the patients who were being housed close to the grounded Ves- pasian, and by sunace or air transpon to tne more distant shelters, the medication and supplies of synthetic nutrient were being distributed by every Monitor Corps entity available, which meant all but the capital ship's watch-keeping and communications officers and those charged with the maintenance of the air and surface vehicles. Lioren, whose injuries were still hampering his mobility, divided his attention between communications and the sick bay, where he was the only medic on duty.

The dosage administered varied in proportion to the age, body mass, and clinical condition of the patients. With the very young it was triple that recommended for trial purposes by Thornnastor, and, making due allowance for the potency of the medication, for those close to termination it was massive. Priority should have been given to the more serious cases, but there was so much variation in the degree of illness within small groups that it saved time if everyone was treated as and when they were encountered.

It quickly developed into a routine that was too frenetic to be described as boring. A few words of explanation and reassurance would be given, the single injection administered, and food and water placed within easy reach of the patient, who was usually too ill to make anything but a verbal objection; then it would be on to the next one.

By the end of the third day the entire population had been treated and the second phase began, that of visiting the patients, on a daily basis if possible, to replenish the consumables and observe and report on any change in their clinical condition. The medical and support staff worked day and night, eating infrequently of the same bland, synthetic food supplied to their patients and sleeping hardly at all. Increasing fatigue caused a forced landing and two ground-vehicle accidents, none of which involved fatalities, so that the ship's hospital no longer held only plague victims.

On the fourth day one of his adult Cromsaggar in sick bay terminated, but the number of deaths outside the ship went down to one hundred and fifteen. On the fifth day the figure had dropped to seven, and there were no fatalities reported on the sixth day.

Except for the difference in scale and the continuing effort needed to keep the widely dispersed patients supplied with food, the situation in sick bay reflected the clinical conditions outside.

As Thornnastor had predicted, a gradual remission in external symptoms was apparent and the food requirement of the adult patients had increased, and the fact that all of the food had been synthesized made no difference to their appetites. Much as he wanted to monitor their progress internally, they would not cooperate and refused to allow him to so much as touch them. With all of his medical staff and the majority of the ship's crew scattered across the continent, he thought it better not to force the issue, especially as the patients were growing stronger with every day that passed. In spite of the differences in body mass, the young were eating more than the adults, and, as Thornnastor had also observed, their rate of physical growth was phenomenal.

It was obvious that, in order to cause such a massive retardation of growth, the disease, which the Cromsaggar had acquired prenatally, must have involved the entire endocrine system. Now that the process was being reversed and they were not only growing but maturing, another, nonclinical change was occurring. The young patients who, once their initial fear had given way to curiosity and they had grown accustomed to his strange body and multiplicity of limbs, had spoken to him freely and with the unguarded enthusiasm of children were becoming increasingly reticent.

They were speaking to him less because, Lioren observed, their recovering elders were talking to them more. And they talked only when he was not present.

By then his Monitor Corps patients had been well enough to be discharged to continue their recuperation in their own quarters, so he did not know what the Cromsaggar talked about until one day, after replenishing the food supply and his few words of friendship and reassurance had been ignored, he deliberately left one of the sick-bay senders switched on Transmit so that he would be able to listen to them from his own quarters.

In the manner of all eavesdroppers, he fully expected to overhear unkind things about himself and the bad dreams from the sky, which was the literal translation of the Cromsaggar name for their rescuers. But he was completely wrong. Instead, they talked and chanted and sang together so that his translator was unable to separate the individual voices. It was only when a single Cromsaggar spoke out alone, an adult addressing one or more of the young, that Lioren realized what he was hearing.

It was part of an initiation ceremony, a preparation and for-malized sex instruction given to the newly mature before entry into adult life, including the behavior expected of them thereafter.

Lioren broke the connection hastily. The rite of passage into adulthood was a highly sensitive area in the cultures of many intelligent species, and one into which he was not qualified to delve. If he were to continue listening out of mere lascivious curiosity, he might find that he no longer respected himself.

He was relieved, nevertheless, that with the exception of two very small children who were little more than infants, the sick bay held only male Cromsaggar.

During the days that followed there were no organic fatalities reported, but the air and surface vehicles, which had been in continuous operation over eight days and nights, had not fared so well. The food synthesizers on Vespasian and in the outlying medical stations were running at maximum safe overload, a condition that was not recommended for more than a few hours at a time. All of the organic components were displaying signs of stress and severe fatigue but were operating at close to optimum efficiency, even though they rarely talked to each other and seemed to be asleep on their feet. It was becoming clear to everyone concerned that the operation was a success and that no member of the patient population was about to die, and that knowledge was both the fuel and the lubrication which kept them working.

It was irritating to all of them, but not important, that the Cromsaggar showed no gratitude for what was being done for them apart from demolishing the previous day's food supply. The brief explanation of the treatment and reassurance regarding their ultimate cure that was given at every visit to replenish stores was ignored. The patients were not actively hostile, unless one of the medics tried to check on their vital signs or obtain a blood sample, whereupon they reacted violently toward the person concerned.

An ungrateful and unlikable race, Lioren thought, not for the first time. But it was their physiology rather than their psychology which was his problem, and the problem was being solved.

From Sector General there was a continuing silence.

He could imagine Thornnastor's slow, careful progress, with its relatively few patients, toward a stage in the treatment which

Lioren had already surpassed with the entire planetary population. It was no reflection on the Tralthan pathologist, who was, after all, the entity responsible for producing the cure for the plague. But if Lioren had not ignored its recommendations and risked the displeasure of his superiors, many hundreds of Crom-saggar would have died by now. And without false modesty on his part, the solution he had devised for the problem had been truly elegant.

His calculated variation in the dosage administered, based as it had been on age, body mass, and clinical factors, had insured that the young and old alike were progressing toward a complete cure at the same time. In spite of his insubordination, he was sure that his action would merit praise rather than censure.

Early on the following day he sent a brief message to the Monitor Corps base on Orligia, and copied to Sector General, requesting additional food synthesizers and spares for the air and ground transport units, adding that there had been no Crom-saggar fatalities for eight days and that a full report accompanied by a medical officer with firsthand experience of the situation was being sent with Tenelphi to the hospital. The request for synthesizers combined with the sudden drop in the death rate would tell Thornnastor what Lioren had done, and the scout ship's medical officer would be able to fill in the details.

Dracht-Yur had been working well and very hard, and ordering its return to normal duties on Tenelphi would be both a rest and a well-deserved reward for its efforts. It would also remove the Surgeon-Lieutenant from the scene and thereby make it possible for Lioren, whose injuries were healing well, to escape the little Nidian's irksome medical quarantine.

Before retiring that night Lioren posted the usual guard outside the sick bay, an unnecessary precaution because none of the Cromsaggar had shown any interest in what lay beyond the entrance, but necessary in Captain Williamson's opinion in case one of the young ones decided to go exploring and injured itself on ship equipment. Tomorrow he would fly to the outlying medical shelters and, for the first time since his embarrassing mishap with the mating Cromsaggar, view the situation for himself.

He would be seeing, Lioren told himself with mixed feelings of pleasure, pride, and self-congratulation, the final stages of the cure of Cromsag.

Before he was due to board his flier next morning he visited

sick bay to check on the condition of his patients, only to find the deck and walls splattered with Cromsaggar blood and all of the adults dead. The entrance guard, after succumbing to a violent attack of nausea, reported hearing quiet voices and chanting that had continued far into the night, followed by a period of unbroken silence which it had attributed to them being asleep. But from the condition of the bodies it was clear now that they had instead been fighting and silently kicking, biting, and tearing the lives out of each other until only two of the female infants survived.

Lioren was still trying to recover from the shock, and make himself believe that he was not asleep and having a particularly horrendous dream, when the wall speaker beside him came to sudden, noisy life. It said that he should go at once to the communications center and that the bloody, self-inflicted massacre in sick bay had been repeated all over Cromsag.

Very soon it became clear that Surgeon-Captain Lioren was responsible not for curing but for killing a planetary population.

Chapter 5

WHEN Lioren finished speaking there was complete stillness in the room. Even though all present were already aware of every harrowing detail of the Cromsag Incident and his responsibility for it, the mere repetition was enough to shock any civilized being into silence.

"The guilt in this matter is entirely mine," Lioren resumed, "and lest there be any doubt about this in anyone's mind, I ask Thornnastor, the Diagnostician-in-Charge of Pathology, to give its evidence."

The Tralthan lumbered forward on its six elephantine feet to take the witnesses position, and, fixing one eye each on the president of the court, Lioren, O'Mara, and its printed notes, it began to speak. Within a tew minutes Meet commander uer-mod was holding up one hand for silence.

"The witness is not obliged," it said, "to relate its evidence in such clinical detail. No doubt its medical colleagues would find it interesting but it is not understandable by the court. Please simplify your language, Diagnostician Thornnastor, and go to the explanation of why the Cromsaggar acted as they did."

Thornnastor stamped its two medial feet in a gesture which suggested impatience, but whose exact significance would have been clear only to another Tralthan, and said, "Very well, sir. . ."

Because of the more cautious approach to the trial program at Sector General and the consequently slower progress toward a complete cure, Thornnastor explained, the hypersignal from Vespasian was received in time to prevent a repetition of the catastrophe that had occurred on Cromsag. All of the Cromsaggar had been dispersed and confined to single quarters, and the Department of Other-species Psychology had intensified its efforts to overcome the fanatical noncooperation of the patients so that they would answer questions about themselves.

It was only when the decision had been made, very reluctantly and only after lengthy consideration of possible psychological damage, to tell the patients the whole truth of what had happened on their home planet, including the fact that they were the sole surviving adult members of their race, that they began to talk about themselves. There was much anger and recrimination, understandably, but enough information was provided to make possible the formation of a theory which was supported by the archeological evidence.

The best estimate was that the plague had made its first appearance just under one thousand years ago, when the Cromsaggar level of technological and philosophical advancement included atmospheric flight and a culture that no longer practiced war. No information was available regarding the origin and evolution of the disease other than that it was transmitted by either parent during sexual coupling and, in the beginning, its effects had been mild and embarrassing rather than life-threatening. The majority of the Cromsaggar did not travel widely, and they took their sexual bondings, once formed, very seriously and did not stray in this respect, either. A number of the more farsighted Cromsaggar formed communities that were piaguc-ncc, uui me mauiig pruucss ucpcnucu on einuiiunai rather than medical factors and eventually the disease broached this immaterial defense. Another three centuries were to pass before the plague spread unchecked across all of Cromsag to infect every member of the population, adult and child alike. By that time it had increased in virulence, and deaths in middle age were becoming common.

The continuing efforts of the medical scientists were of no avail, and by the end of the following century their civilization had receded to pretechnology levels with no hope of a revival, and it was rare for anyone to live more than a decade past maturity. As a race, the Cromsaggar were facing extinction, a very early extinction because of the effect of the plague on the birth rate.

"The complete symptomology of the disease," Thornnastor said, "including the endocrinological involvement with its effect on the sufferers' rate of growth and maturation, has already been studied and can be discussed at length, but I shall summarize and simplify for the benefit of the court.

"Among the adults of both sexes," it went on, "the visually and tactually unpleasant skin condition was one factor in the reducing birth rate, but it was a minor one. Even if the tegument of both partners was flawless and aesthetically pleasing, the greatly reduced performance of the endocrine system is such that the act of sexual coupling and conception is impossible without an abnormal level of prior emotional stimulation."

Thornnastor paused. It did not possess the kind of features which could change expression, but it was as if the mind-pictures it was seeing inside its great, immobile dome of a head had made further speech impossible for a moment. Then it went on. "Efforts were made to circumvent this difficulty by medical means, and by the use of substances derived from naturally occurring vegetation which heightened the senses or had hallucinatory effects. These methods proved ineffective and were discarded because of problems of irreversible addiction, death from overdose, and seriously deformed and nonviable offspring. The solution that was ultimately found was nonmedical and involved a deliberate regression in social behavior to the dark ages of their history.

"The Cromsaggar went to war . . ."

It was not a war fought for reasons of territorial expansion or trade advantage, and neither was it fought at a distance from fortified positions or by warriors acting in concert or protected by armored machines or equipment, and it was a war not waged to the death because there was no intention on either side of killing an opponent who might very well be a family member or a friend. In fact, there were no sides because it was fought hand to hand between pairs of unarmed individuals, and it was a war whose sole purpose was to cause the maximum of fear, pain, and danger, but if possible, not death to the combatants. There was no threat or danger from a beaten and seriously wounded opponent and, even though they had been trying desperately to kill each other moments before, the vanquished were left where they lay, hopefully to recover from their wounds to fight and instill fear in an opponent another day.

Life was rare and precious to the Cromsaggar, rarer and more precious with every dwindling generation that passed; otherwise they would not have tried so hard to keep their race alive.

For it was only by overloading the sensorium with pain and intense muscular effort and subjecting themselves to the highest possible levels of emotional stress that endocrine systems rendered dormant by the eifects of the plague could be roused into something like normal activity, and remain so, aside from the wounds that had been sustained, for the time necessary for a successful coupling and procreation to take place.

But in spite of the terrible solution that had been found, adult deaths from the plague continued to rise and the birth rate to fall. The population contracted in numbers and territory occupied, moving to one continent so as to conserve what little was left of their civilization and resources and to be within easy fighting distance of each other. There was archeological evidence to suggest that in the beginning the Cromsaggar were not warlike, but the need to fight and often kill each other so that their race as a whole could survive made them so, and by the time Tenelphl discovered them, the practice of hand-to-hand combat among all adults had been conditioned into the race for many centuries.

"Even though the decision was taken for the best of all clinical reasons, that of saving many lives," Thornnastor went on, "without prior knowledge of this conditioning, the effect of introducing a complete and short-duration cure for the plague could not have been foreseen. It is probable, and Chief Psychologist

O'Mara agrees with me in this, that the Cromsaggar who had been treated were aware of feeling better and stronger than they had ever felt before, and subconsciously they must have realized that it was no longer necessary for them to fight and place themselves in the greatest possible danger in order to achieve sexual arousal. But for many centuries they had been taught from an early age that single combat between members of one's own sex invariably preceded coupling with one of the opposite, a level of conditioning with the strength of an evolutionary imperative. And so, the more their clinical condition improved the greater was their urge to fight and procreate. The many young, whose physical development had been retarded by the effects of the plague and who had suddenly come to maturity, felt the same compulsion to fight.

"But the real tragedy," the Tralthan continued, "lay in the fact that individually and as a group they were fully cured, and stronger than any Cromsaggar had been since the coming of the plague. Previously they had been weak, diseased, and able to expend only a small fraction of the physical effort of which they were now capable. Their newfound strength reduced the personal fear of pain and death, and made it difficult to calibrate the levels of damage inflicted on and by opponents who were so strong and evenly matched. The result was that they killed each other, every single adult on Cromsag, leaving only the infants and children alive.

"Briefly and simply," Thornnastor ended, "that is the background to the Cromsag Incident."

The silence that followed Thornnastor's words lengthened and deepened until the faint, bubbling sound made by the refrigerated life-support system of an SNLU in the audience seemed loud. It was like the Tarlan Silence of Remembrance after the passing of a friend, except here it was the population of a world that had died and it seemed that no person present was going to break it.

"With respect to the court," Lioren said suddenly, "I ask that the trial be ended here and now, without further argument and waste of time. I stand accused of genocide through negligence. I am guilty without doubt or question and the responsibility and the guilt are entirely mine. I demand the death penalty."

O'Mara rose to his feet before Lioren had finished speaking.

The Chief Psychologist said, "The defense would like to correct the accused on one very important point. Surgeon-Captain Lioren did not commit genocide. When the incident occurred it reacted quickly and correctly in the circumstances, by warning the hospital and organizing the rescue and care of the newly orphaned Cromsaggar children, this in spite of the fact that many of its own people had been so taken by surprise that they were unable to use the gas in time, and who were seriously injured in attempts to stop the fighting. During this period the Surgeon-Captain's behavior was exemplary and, although the witnesses are not here present, their evidence was presented to and accepted by the civil court on Tarla and is on record—"

"The evidence is not disputed," Lioren broke in impatiently. "It is not relevant."

"As a result of this timely warning and subsequent actions," O'Mara continued, ignoring the interruption, "the adult Cromsaggar under treatment here were separated before they could attack each other, and the young, both here and on Cromsag, were saved. Altogether thirty-seven adults and two hundred and eighty-three children, with a roughly equal distribution of sex, are alive and well. I have no doubt that, after a lengthy period of reeducation, resettlement, and specialized assistance in breaking their conditioning, Cromsag will be repopulated, and, now that the plague has been removed, its people will return to living together in peace.

"It is understandable that the accused should feel an overwhelming guilt in this matter," the psychologist went on in a quieter voice. "Had that not been so, it would not have caused this court-martial to be convened. But it is possible that the great guilt that it feels over the Cromsag Incident, together with its urgent need to discharge that guilt and its impatience to receive punishment for the alleged crime, has caused it to exaggerate its case. As a psychologist I can understand and sympathize with its feelings, and with its attempts to escape the burden of its guilt. And I am sure that there is no need to remind the court that, among the sixty-five intelligent species who make up the Galactic Federation, not one of them practices judicial execution or physical chastisement during confinement."

"You are correct, Major O'Mara,'' the fleet commander said. "The reminder is unnecessary and time-wasting. Make your point briefly."

The color of O'Mara's facial skin deepened slightly, and it said, "The Cromsaggar are not extinct, and they will continue to survive as a race. Surgeon-Captain Lioren is guilty of exaggeration, but not genocide."

All at once Lioren felt anger, despair, and a terrible fear. He kept one eye on O'Mara and directed the other three individually toward the officers of the court and forced calmness and clarity onto his mind as he said, "The exaggeration, this small inaccuracy that was intended only as a simplification of a terrible truth, is unimportant because the enormity of my guilt is beyond measure. And I should have no need to remind Major O'Mara of the punishment, the destruction of a medic's professional future rather than life, which is meted out to any member of the staff whose carelessness or lack of observation leads to the clinical deterioration or death of a patient.

"I am guilty of negligence," Lioren went on, wishing that the translator could reproduce the desperation in his voice, "and the defense counsel's attempt to belittle and excuse what I have done is ridiculous. The fact that others, including the hospital personnel concerned with the trials of the medication, were also surprised by the Cromsaggar behavior is not an excuse. I should not have been surprised, because all the information was available to me, all the clues to the puzzle were there if I had correctly read the signs. I did not read them because I was blinded by pride and ambition, because a part of my mind was thinking that a rapid and total cure would enhance my professional reputation. I did not read them because I was negligent, unobservant, and mentally fastidious in refusing to listen to patients' conversations relating to Cromsaggar sex practices which would have given a clear warning of what was to happen, and because I was impatient of superiors who were advocating caution—"

"Ambition, pride, and impatience," O'Mara said, rising quickly to its feet, "are not crimes. And surely it is the degree of professional negligence, if any, that the court must punish, not the admittedly terrible and far-reaching effects of what is at most a minor transgression."

"The court," Fleet Commander Dermod said, "will not allow counsel to dictate to it, nor will it allow another such interruption of the prosecution's closing statement. Sit down, Major. Surgeon-Captain Lioren, you may proceed."

The guilt and the fear and the desperation were filling Lioren's mind so that the finely reasoned arguments he had prepared were lost and forgotten. He could only speak simply of how he felt and hope that it would be enough.

"There is little more to add," he said. "I am guilty of a terrible wrong. I have brought about the deaths of many thousands of people, and I do not deserve to live. I ask the court for mercy, and for the death sentence."

Again O'Mara rose to its feet. "I am aware that the prosecution is allowed the last word. But with respect, sir, I have made a detailed submission regarding this case to the court, a submission which I have not had the opportunity of introducing for discussion."

"Your submission was received and has been given due consideration," the fleet commander said. "A copy was made available to the accused, who, for obvious reasons, chose not to introduce it. And may I remind defense counsel that it is I who will have the last word. Please sit down, Major. The court will confer before passing sentence."

The misty gray hemisphere of a hush field appeared around the three officers of the court, and it seemed that everyone else might have been enclosed in the same zone of silence as their eyes turned on Lioren. In spite of it being at extreme range for an empath, at the rear of the audience he could see Prilicla trembling. But this was not a time when he could control his emotional radiation. When he remembered the contents of O'Mara's submission to the court, he felt the most dreadful extremes of fear and despair overwhelming his mind and, for the first time in his life, an anger so great that he wanted to take the life of another intelligent being.

O'Mara saw one of his eyes looking in its direction and moved its head slightly. It was not an empath, Lioren knew, but it must be a good enough psychologist to know what was in Lioren's mind.

Suddenly the hush field went down and the president of the court leaned forward in its chair.

"Before pronouncing sentence," the fleet commander said, looking toward O'Mara, "the court wishes clarification and reassurance from defense counsel regarding the accused's probable behavior in the event of a custodial rather than the death sentence being imposed. Bearing in mind Surgeon-Captain

Lioren's present mental state, isn't it likely that either sentence would quickly result in the accused's death?"

O'Mara rose again. Its eyes were on Lioren rather than the fleet commander as it said, "In my professional opinion, having observed the accused during its training here and studying its behavior subsequent to the Cromsag Incident, it would not. The Surgeon-Captain is an ethical and highly moral being who would consider it dishonorable to escape what it will consider to be a justly imposed punishment for its crime by means of suicide, even though a custodial sentence would be the harshest, in terms of continued mental distress, that could be imposed. However, as the court will recall from my submission, I prefer the term 'remedial' to 'custodial.' To reiterate, the accused would not kill itself but it would, as you have already gathered, be most grateful if the court would do the job for it."

"Thank you, Major,'' the fleet commander said; then it turned to face Lioren.

"Surgeon-Captain Lioren," it said, "this court-martial upholds the earlier verdicts of your own civil and medical courts on Tarla, your home world, and finds you guilty of an excusable error in observation and judgment which led, regrettably, to a major catastrophe. Although it would be kinder in the circumstances to do so, we will not depart from Federation judicial practice of three centuries, or waste a potentially valuable life should the therapy prove successful, by imposing the death sentence that you so plainly desire. Instead you are to be given a custodial and remedial sentence of two years, stripped of your Monitor Corps and medical rank, and forbidden to leave this hospital, which is an establishment large enough for your confinement not to prove irksome. For obvious reasons you are also forbidden access to the Cromsaggar ward. You will be placed in the charge and under the direction of Chief Psychologist O'Mara. In that time the major expects to bring about a psychological and emotional readjustment which will enable you to begin a new career.

"You have the court's deepest sympathy, ex-Surgeon-Captain Lioren, and its best wishes."

Chapter 6

LIOREN stood on the clear area of floor in front of O'Mara's desk, surrounded on three sides by the strangely shaped furniture designed for the comfort of physiological classifications other than his own, and stared down at the psychologist with all of his eyes. Since the imposition of the sentence and a regimen that nothing in his power could change, the intensity of his feelings toward the stocky little biped with its gray head fur and eyes that never looked away had diminished from a life-threatening hatred to a level of dislike so deeply etched into Lioren's mind that he did not believe that it could ever be erased.

"Liking me is not a prerequisite of the treatment, fortunately," O'Mara said, seeming to read Lioren's mind; "otherwise Sector General would be without its medical staff. I have made myself responsible for you and, having read a copy of my written submission to the court-martial, you are aware of my reasons for doing so. Need I restate them?"

O'Mara had argued that the principal reason for what had happened on Cromsag had been due to certain character defects in Lioren, faults which should have been detected and corrected during its other-species medical training at Sector General, and this was an omission for which the Psychology Department was entirely to blame. That being the case, and bearing in mind the fact that Sector General was not a psychiatric hospital, Lioren could be considered as a trainee who had not satisfactorily completed his training in other-species relations rather than a patient, and be attached to the Psychology Department under O'Mara's supervision. In spite of his proven medical and surgical ability with many life-forms, as a trainee he would have less status than a qualified ward nurse.

"No," Lioren said.

"Good," O'Mara said. "I dislike wasting time, or people. At present I have no specific orders for you other than that you will move freely within the hospital, initially with an escort from this department, or, if there are times when this causes an unacceptable level of embarrassment or distress, you will perform routine office tasks. These will include you familiarizing yourself with the work of the department and the medical staff psych files, most of which will be opened to you for study. Should you uncover any evidence of unusual behavior, uncharacteristic reactions toward other-species staff members, or unexplained reductions in professional standards, you will report it to me, having first discussed it with one of your department colleagues to insure that it is worth my attention.

"It is important to remember," the psychologist went on, "that with the exception of a few of the most gravely ill patients, everyone in the hospital knows all about your case. Many of them will ask questions, polite and considerate questions for the most part, except the Kelgians, who do not understand the concept of politeness. You will also receive many well-intentioned offers of help and encouragement and much sympathy."

O'Mara paused for a moment; then, in a softer voice, it continued. "I shall do everything that I can to help you. Truly, you have suffered and are suffering a great mental anguish, and laboring under a burden of guilt greater than any I have encountered in the literature or in my own long experience; a load so heavy that any other mind but yours would have been utterly destroyed by it. I am greatly impressed by your emotional control and horrified at the thought of your present level of mental distress. I shall do everything possible to relieve it and I, too, who am in the best position of anyone other than yourself to understand the situation, offer you my sympathy.

"But sympathy," it went on, "is at best a palliative treatment, and one which diminishes in effect with repeated application. That is why I am applying it on this one and only occasion. Henceforth, you will do exactly as you are told, perform all the routine, menial, boring tasks set you, and you will receive no sympathy from anyone in this department. Do you understand me?"

"I understand," Lioren said, "that my pride must be humbled and my crime punished, for that is what I deserve." O'Mara made an untranslatable sound. "What you think you deserve, Lioren. When you begin to believe that you might not deserve it, you will be well on the way to recovery. And now I will introduce you to the staff in the outer office."

As O'Mara had promised, the work of the office was routine and repetitious, but during the first few weeks it was still too new for him to find it boring. Apart from the periods spent sleeping, or at least resting, or using his room's food dispenser, Lioren had not left the department, nor had he exercised anything but his brain. His concentration on the new duties was total, and as a result the quality, quantity, and his understanding of the work increased to the point where it drew praise from both Lieutenant Braithwaite and Trainee Cha Thrat, although not from Major O'Mara.

The Chief Psychologist never praised anyone, it had told him, because its job was to shrink heads, not swell them. Lioren could not make any clinical or semantic sense of the remark and decided that it must be what the Earth-human DBDGs called a joke.

Lioren could not ignore his growing curiosity about the two beings with whom he was spending so much time, but the psych files of departmental personnel were closed to each other, and they neither asked personal questions nor answered any about themselves. Possibly it was a departmental rule, or O'Mara had told them to keep a rein on their natural curiosity out of consideration for Lioren's feelings, but then one day Cha Thrat suggested that the rule did not apply outside the office.

"You should forget that display screen for a while, Lioren," the Sommaradvan said as it was about to leave for its midday meal, "and rest your mind from Cresk-Sar's interminable student progress reports. Let's refuel."

Lioren hesitated for a moment, thinking about the permanently crowded dining hall for the hospital's warm-blooded oxygen-breathers and the people he would have to meet in the busy corridors between. Lioren was not sure if he was ready for that.

Before he could reply, Cha Thrat said, "The catering computer has been programmed with a full Tarlan menu, synthetic, of course, but much better than that tasteless stodge the room dispensers dish out. That computer must be feeling hurt, ag- grieved, even insulted at being ignored by the only Tarlan on the staff. Why not make it happy and come along?"

Computers did not have feelings, and Cha Thrat must know that as well as he did. Perhaps it was making a Sommaradvan joke.

"I will come," Lioren said.

"So will I," Braithwaite said.

It was the first time in Lioren's experience that the outer office had been left unattended, and he wondered if one or both of them were risking O'Mara's displeasure by doing so. But their behavior on the way to the dining hall, and the firm but unobtrusive manner in which they discouraged any member of the medical staff who seemed disposed to stop him and talk, made it plain that they were acting with the Chief Psychologist's approval. And when they found three vacant places at a table designed for the use of Melfan ELNTs, Braithwaite and Cha Thrat made sure that he remained between them. The other occupants, five Kelgian DBLFs noisily demolishing the character of some unnamed Charge Nurse as they were rising to leave, could not be avoided. Nothing was proof against Kelgian curiosity.

"I am Nurse Tarsedth," one of them said, turning its narrow, conical head to point in Lioren's direction. "Your Sommaradvan friend knows me well, since we trained together, but does not recognize me because it insists that, in spite of having four eyes, it cannot tell Kelgians apart. But my questions are for you, Surgeon-Captain. How are you feeling? Does your guilt manifest itself in bouts of psychosomatic pain? What therapy has O'Mara devised for you? Is it effective? If not, is there anything I can do to help?"

Suddenly Braithwaite started making untranslatable sounds, and its facial coloring had changed from pinkish yellow to deep red.

Tarsedth looked at it briefly, then said, "This often happens when the food and air passages share a common entrance channel. Anatomically, the Earth-human DBDG life-form is a mess."

Anatomically, Lioren thought as he tried hard to concentrate on the questioner in an attempt to avoid the pain that its questions were causing, the Kelgian was beautiful. It was physiological classification DBLF, warm-blooded, oxygen-breathing, multi-pedal, and with a long, flexible cylindrical body covered overall by highly mobile, silvery fur. The fur moved continually in slow ripples from its conical head right down to the tail, and with tiny cross-eddies and wavelets appearing as if the incredibly fine pelt were a liquid stirred by an unfelt wind. It was that fur which explained, and excused, the other's rude and direct approach to what it must know to be a sensitive subject.

Because of inadequacies in the Kelgian speech organs, their spoken language lacked modulation, inflection, and any emotional expression, but they were compensated by the fur, which acted, so far as another Kelgian was concerned, as a perfect but uncontrollable mirror of the speaker's emotional state. As a result the concept of lying or being diplomatic, tactful, or even polite was completely alien to them. A Kelgian said exactly what it meant or felt because its fur revealed its feelings from moment to moment, and to do otherwise would have been considered a stupid waste of time. The opposite also held true, because politeness and the verbal circumlocutions used by many other species simply confused and irritated them.

"Nurse Tarsedth," Lioren said suddenly, "I am feeling very unwell, but on the psychological rather than the physical level. The therapy O'Mara is using in my case is not yet clear to me, but the fact that I have visited the dining hall for the first time since the trial, even though accompanied by two protectors, suggests that it is beginning to work, or that my condition may be improving in spite of it. If your questions are prompted by more than mere curiosity and the offer of help intended to be taken as more than a verbal kindness, I suggest that you ask for details of the therapy and its progress, if any, from the Chief Psychologist."

"Are you stupid?" the Kelgian said, its silvery pelt tufting suddenly into spikes. "I would not dare ask a question like that. O'Mara would tear my fur off in small pieces!"

"Probably," Cha Thrat said as Tarsedth was leaving, "without benefit of anesthetic."

Their food trays slid from the table's delivery recess to the accompaniment of an audible signal that kept him from hearing the Kelgian's reply. Braithwaite said, "So that's what Tarlans eat," and thereafter kept its eyes averted from Lioren's platter.

In spite of having to eat and speak with the same orifice, the Earth-human kept up a continuous dialogue with Cha Thrat, during which they both left conversational gaps enticingly open so that Lioren could join in. Plainly they were doing their best both to put him at ease and keep his attention from the nearby tables where everyone was watching him, but, with a member of a species who had to make a conscious mental effort not to look in every direction at once, they were having little success. It was also plain that he was undergoing psychotherapy of a not very subtle form.

He knew that Cha Thrat and Braithwaite were fully informed about his case, but they were trying to make him repeat the information verbally so as to gauge his present feelings about himself and those around him. The method they were using was to exchange what appeared to be highly confidential and often personal information about themselves, their past lives, their personal feelings about the department and toward O'Mara and other entities on the hospital staff with whom they had had pleasant or unpleasant contact, in the hope that Lioren would reciprocate. He listened with great interest but did not speak except in answer to direct questions from them or from staff members who stopped from time to time at their table.

Questions from the silver-furred Kelgians he answered as simply and directly as they were asked. To the shy well-wishings of a massive, six-legged Hudlar whose body was covered only by a recently applied coat of nutrient paint and the tiny ID patch of an advanced student nurse he replied with polite thanks. He also thanked an Earth-human called Timmins, wearing a Monitor Corps uniform with Maintenance insignia, who hoped that the Tarlan environment in his quarters had been properly reproduced, and said that if there was anything else that would make him feel more comfortable he should not hesitate to ask for it. A Melfan wearing the gold-edged band of a Senior Physician on one crablike arm stopped to say that it was pleased to see him making use of the dining hall, because it had wanted to speak to the Tarlan but that, regrettably on this occasion, it was due in ELNT Surgery. Lioren told it that he intended using the dining hall regularly in the future and that there would be other opportunities to talk.

That reply seemed to please Braithwaite and Cha Thrat, and when the Melfan Senior left them they resumed the conversation whose gaps Lioren steadfastly refused to fill. If he had chosen to speak and reveal his feelings just then, it would have been to say that, having been condemned to live for the terrible crime he had committed, he must accept as part of the punishment these constant reminders of his guilt.

He did not think they would be pleased to hear that.

The members of the Psychology Department, Lioren discovered, were free to move anywhere within the hospital and talk to or question, at any time which did not adversely affect the performance of the individual's professional duties, everyone from the lowest trainee nurse or maintenance person up to the near godlike Diagnosticians themselves, and it came as no surprise that their authority to pry into everyone else's most private and personal concerns made them very few friends among the staff. The surprises were the manner in which these multispecies psychologists were recruited and their prior professional qualifications, if any.

O'Mara had joined Sector General shortly before it had been commissioned, as a structural engineer, and the work it had done among the original staff and patients that resulted in its promotion to major and Chief Psychologist was no longer open for study, although there was a rumor that it had once wet-nursed an orphaned infant Hudlar unaided and without benefit either of heavy-lifting machinery or translation devices, but that story Lioren considered to be too wildly improbable to have any basis in fact.

From the words spoken and unspoken it seemed that Lieutenant Braithwaite's career had begun in the Corps's Other-Species Communications and Cultural Contact Division, where initially it had shown great promise and an even greater impatience with its superiors. It was enthusiastic, dedicated, self-reliant, and intuitive where its work was concerned, and whether its intuition proved trustworthy, as happened in the majority of cases, or unsafe, the result was deeply stressful to those in authority. Its attempt to expedite the First Contact procedure on Keran by circumventing the philosophically conservative priesthood caused a citywide religious riot in which many Keranni were killed and injured. Thereafter it was disciplined before being transferred to a number of subordinate administrative positions, none of which proved suitable either to Braithwaite or its superiors, before coming to Sector General. For a short time it was attached to the Maintenance Department's internal-communications section until, in an attempt to rewrite and simplify the multispecies translation program, it knocked down the main computer and left the entire hospital staff and patients unable to do anything but bark, gobble, or cheep unintelligibly at each other for several hours. Colonel Skempton had been less impressed by what Braithwaite had hoped to do than by the havoc it had caused, and was about to banish it to the loneliest and most distant Monitor Corps outpost in the Federation when O'Mara had intervened on its behalf.

Similarly, Cha Thrat's career had been beset by personal and professional difficulties. It was the first and so far only Som-maradvan female to qualify and practice as a warrior-surgeon, a position of great eminence in a profession which was otherwise exclusively male. Lioren was unsure of what a warrior-surgeon of that planet was supposed to be or do, but it had been able to treat successfully a member of an off-planet species, an Earth-human Monitor Corps officer very seriously injured in a flier crash, that Cha Thrat had encountered for the first time. Impressed by its surgical skills and flexibility of mind, the Corps had offered it the opportunity of training in multispecies surgery at Sector Twelve General Hospital. Cha Thrat had accepted because, unlike on its home world, the other-species doctors there would judge it on professional merit without caring whether it was male or female.

But the intense dedication and rigorous clinical disciplines of a warrior-surgeon of Sommaradva, which in many respects resembled those of Lioren's own Tarlan medical fraternity, were not those of Sector General. Cha Thrat did not go into the details of its misdemeanors, suggesting instead that any member of the staff would be eager to satisfy Lioren's curiosity in the matter, but the impression given was that as a trainee it had exercised its clinical initiative too freely, and too often proved its nominal superiors wrong. After one particular incident during which it had temporarily lost one of its own limbs, no ward in the hospital would accept it for training and it, like Braithwaite, had been transferred to Maintenance until a major act of insubordination warranted by the clinical situation at the time brought about its dismissal. And, again like Braithwaite, it was O'Mara who had kept Cha Thrat from leaving the hospital by recruiting it for the department.

As the conversation that was designed both to inform and to draw him out continued, Lioren felt a growing sympathy for these two entities. Like himself they had been cursed with too much intelligence, individuality, and initiative and had suffered grievously thereby.

Naturally, their crimes were insignificant compared with Lioren's own, because they were psychologically flawed misfits rather than criminals and not fully responsible for the wrongs they had done. But were they confessing those misdeeds to him in the form of an apparently unimportant exchange of gossip, ostensibly so that he would better understand them and the situation within the department? Or was it an attempt to assuage their own guilt by trying to help him? He could not be sure because they were concealing their true feelings, unlike himself, by talking too much rather than by remaining silent. The thought that they might not be suffering at all, that their efforts to help Lioren and their other department duties made them forget their past misdeeds came to trouble him, but he dismissed the idea as ridiculous. One could no more forget a past crime than one's own name.

"Lioren," Braithwaite said suddenly. "You are not eating and neither are you talking to us. Would you prefer to return to the office?"

"No," Lioren said, "not immediately. It is clear to me that this visit to the dining hall was a psychological test and that my words and behavior have been closely observed. You have also, almost certainly as part of the test, been answering questions about yourselves without my having to ask them, some of them personal questions which I would have considered it most impolite to ask. Now I will ask one question directly of you. As a result of these observations, what are your conclusions?"

Braithwaite remained silent, but with a small movement of its head indicated that Cha Thrat was to answer.

"You have heard and will understand," the Sommaradvan said, "that I am a warrior-surgeon forbidden to practice my true art and am not yet a fully-qualified wizard. For this reason the spells that I cast lack subtlety, as your words have already shown, and are quite transparent. There is a risk that my observations and conclusions, too, may be oversimplified and inaccurate. They are that my spell aimed at bringing you out of the seclusion of the office and your quarters to the dining hall was unsuccessful in that you reacted calmly and with no apparent emotional distress to the entities who approached you. It was unsuccessful in that it did not overcome your unwillingness to reveal personal feelings, which was another and more important purpose of the test. My conclusion is that any future visits to the dining hall should be unaccompanied unless the accompaniment be for social rather than therapeutic reasons."

Braithwaite nodded its head in the Earth-human gesture of silent agreement. "As the subject of this partially successful test, Lioren, what are your own conclusions about it? Express your feelings about that, at least, freely as would a Kelgian, and do not spare ours."

Lioren was silent for a moment, then said, "I feel curious as to why, in this age of advanced medicine and technology, Cha Thrat considers itself to be a wizard, unqualified or otherwise. I also feel surprise and concern regarding the personal information you have revealed to me. At the risk of being grossly offensive, I can only conclude that ... Is the Psychology Department staffed with insubordinate misfits and entities with a history of emotional disturbance?''

Cha Thrat made an untranslatable sound and the Earth-human barked softly.

"Without exception," Braithwaite said.

Chapter 7

NEVER in all his long years as a student on Tarla and during his advanced training at Sector General had Lioren been given such a woolly-minded and imprecise set of instructions.

Surely Major O'Mara, who was reputed to possess one of the finest and most analytical minds in the hospital, should not be capable of issuing such instructions. Not for the first time Lioren wondered if the Chief Psychologist, charged as it was with the heavy responsibility of maintaining the mental health of close on ten thousand medical and maintenance staff belonging to sixty-odd different species, had been affected by one of the non- physical maladies it was expected to treat. Or was it simply that Lioren, as the department's most recent and least knowledgeable recruit, had misunderstood the other's words?

"For my own mental clarification and to reduce the possibility of misunderstanding," Lioren said carefully, "may I repeat my instructions aloud?''

"If you think it necessary," the Chief Psychologist replied. From Lioren's growing experience of reading Earth-human voice sounds and the expressions on their flabby, yellow-pink faces, he knew that O'Mara was losing patience.

Ignoring the nonverbal content of the response, Lioren said, "I am to observe Senior Physician Seldal, for as long and as often as the subject's duty schedule and my other work allows, without drawing attention to the fact that it is under observation. I am to look for evidence of abnormal or uncharacteristic behavior even though you are aware that, to a Tarlan BRLH like myself, normal and characteristic behavior in a Nallajim of physiological classification LSVO would appear equally strange to me. I am to do this without any prior indication of what it is that I am to look for or, indeed, if there is anything to look for in the first place. If I am able to detect such behavior, I should try, covertly, to discover the reason for it, and my report should include suggestions for remedial treatment.

"But what," he went on when it was clear that the other was not going to speak, "if I cannot detect any abnormality?"

"Negative evidence," O'Mara said, "can also be valuable."

"Is it your intention that I proceed in complete ignorance," Lioren asked, anger making him forget for a moment the deference due to a nominal superior, "or will I be allowed to study the subject's psych file?"
