  “I’m restarting the artificial heart,” it said.

  “No, wait,” Conway said sharply. He was looking at the monitor and getting a feeling-a very vague feeling that was not strong enough even to be called a hunch-that any delay at all would be dangerous. “I don’t like the vital signs. There is nothing there which should not be there, considering that the flow from the artificial heart was interrupted, initially by the jammed connector valve and later when the system was shut down during the repair. I realize that if the artificial heart is not restarted within the next few minutes, irreversible changes leading to termination will take place in the brain. Even so, I have the feeling that we should not restart but go instead for an immediate resection of the replacement orgao …

  He knew that Hossantir would want to object and take the safer course, that of restarting the artificial heart and waiting until they were sure that the patient’s circulation had returned to optimum, and then proceed as originally planned. Normally Conway would not have argued against this, because he, too, preferred not to take unnecessary risks. But there was something niggling at the back of his mind, or one of his minds, something about the effect of longterm trauma on certain gravid, heavy-gravity life-forms, and the feeling was so persistent that he had to act on it. And while he had been speaking, Conway had unclipped his instruments to show Hossantir, nonverbally so that the Senior’s feelings would not be hurt too much, that he was not about to argue the point.

  “… Will you work on the connection to the absorption organ, please,” he ended, “and keep an eye on the monitor.”

  Sharing the operative field with the Tralthan, Conway worked quickly and carefully in the restricted space, clamping off the artery beyond the artificial heart connection, detaching it, and reconnecting it to the arterial stub projecting from the replacement organ. Unlike the first, shocking seconds of the earlier hemorrhaging, time seemed to have speeded up. His hands and instruments were well outside the field of the nullifiers, being acted on by four Earth-Gs, so they felt incredibly slow and awkward. Several times his instruments clinked loudly against those of Hossantir. He could sympathize with the surgeon, whoever it had been, who had accidentally knocked that connector valve off its setting. He had to concentrate hard to keep his instruments from leading a life of their own.

  He did not watch Hossantir’s work, because the Tralthan knew its stuff and there was no time for surgical sightseeing.

  He inserted retaining sutures to hold the artery in position on each end of the connector, which was designed both to hold the ends firmly in position when circulation was restored and to keep the sections of original and replacement tissue apart so as to reduce postoperative rejection problems. There were times when, immunologically speaking, he wondered why a highly evolved and complex organism should be its own worst enemy. Next he began the linkup of the vessel which supplied nutrient from the absorption organ to one of the major heart muscles.

  Hossantir had completed its connection and had turned its attention to the minor vessel which supplied one half of the womb when the Hudlar was in female mode-the second, undamaged heart had been performing double duty since the start of the operation. They were short of time, but as yet not dangerously so, when the Tralthan indicated the Monitor with a free appendage.

  “Ectopics,” Hossantir said. “One in five, no, one in four. Pressure is reducing. The indications are that the heart will go into fibrillation and arrest very quickly. The defibrillator is ready.”

  Conway took a quick look at the visual display where the irregular, ectopic heartbeat broke into the normal rhythm once in every four beats. From experience he knew how soon it could degenerate into a rapid, uncontrollable flutter and, with the subsequent loss of the pumping function, failure. The defibrillator would almost certainly shock it into action again, but that device could not be used while the operation on the replacement heart was in progress. He resumed his work with desperate, careful speed.

  So deep was his concentration that all of his minds were becoming involved again, contributing their expertise and at the same time their irritation that it was a set of Earth-human hands which were doing the work and not the assorted manipulators, pincers, and digits of his alter egos. He looked up finally to find that Hossantir and he had finished their connections at the same time. But a few seconds later the other heart went into fibrillation, then arrest. Their time was really short now.

  They eased the clamps on the main artery and secondary vessels and watched the flaccid replacement organ swell slowly as it was filled with Forty-three’s blood, checking with their scanners for the formation of air embolisms. There were none, so Conway placed the four tiny electrodes in position preparatory to restarting the replacement heart. Unlike the defibrillator charge needed for the other heart, which would have to penetrate more than ten inches of hard, Hudlar tegument and underlying tissue, these electrodes would be acting directly on the surface muscles of the replacement organ and would be carrying a relatively mild charge.

  The defibrillator brought negative results. Both hearts fluttered unsteadily for a few moments and then subsided.

  “Again,” Conway said.

  “The embryo has arrested,” Hossantir said suddenly.

  “I was expecting that,” Conway said, not wanting to sound omniscient, but neither did he have the time for explanations.

  Now he knew why he had wanted to complete the replacement connections so fast after the emergency with the valve. It had been not a hunch but a memory from the past when he had been a very junior intern, and the memory was one of his own.

  ft had happened during his first lecture on the FROB life-form, which had been given by the Diagnostician-in-Charge of Pathology, Thornnastor. Conway had made a remark to the effect that the species was fortunate in having a standby heart if one should fail. Conway had meant it as a joke, but Thornnastor had jumped on him, figuratively speaking, with all six of its feet for making such a remark without first studying the Hudlar physiology in detail. It had gone on to describe the disadvantages of possessing two hearts, especially when the possessor was a gravid female-mode Hudlar nearing parturition, and the nerve network which controlled the involuntary muscle system was maintaining a delicate balance between the impulses to four hearts, two parental and two embryonic. At that particular stage the failure of one heart could quickly lead to the arrest of the other three.

  “And again,” Conway said worriedly. The incident had not been worth remembering then, because major surgery on FROBs was considered to be impossible in those days. He was wondering if survival for this particular Hudlar was impossible now when both of its hearts twitched, hesitated, then settled into a strong, steady beat.

  “The fetal hearts are picking up,” Hossantir said. A few seconds later it added, “Pulse-rate optimal.”

  On the sensor screen the cerebral traces were showing normal for a deeply unconscious Hudlar, indicating that there had been no brain damage as a result of the few minutes cessation of circulation, and Conway began to relax. But oddly, now that the emergency was over the other occupants of his mind were becoming uncomfortably obtrusive. It was as if they, too, were relieved and were reacting with too much enthusiasm to the situation. He shook his head irritably, telling himself once again that they were only recordings, simply stored masses of information and experience which were available to his, Conway’s, mind to use or ignore as he saw fit. But then the uncomfortable thought came to him that his own mind was simply a collection of knowledge, impressions, and experience collected over his lifetime, and what made his mind data so much more important and significant than that of the others?

  He tried to ignore that suddenly frightening thought by reminding himself that he was still alive and capable of receiving new impressions and continuously modifying his total experience as a result of them, while the taped material had been frozen at the time it had been donated. In any case, the donors were long since deceased or far removed from Sector General. But Conway’s mind
felt as though it was beginning to doubt its own authority, and he was suddenly afraid for his sanity.

  O’Mara would be furious if he knew Conway was indulging in this kind of thinking. So far as the Chief Psychologist was concerned, a Doctor was responsible for his work and for the tools, both physical and psychological, which enabled him to do that work. If the Doctor could not perform satisfactorily, then the person concerned should seek a less demanding job.

  There were few jobs more demanding than that of a Diagnostician.

  His hands were beginning to feel wrong again, and the fat, pink, and strangely awkward fingers were trembling. Conway stowed away his DBDG instruments and turn — ed to Hossantir’s Melfan assistant, whose ID was still smeared with blood and only partly readable, and said, “Would you like to resume, Doctor?”

  “Thank you, sir,” the ELNT said. Obviously it had been worrying in case Conway, as a result of his intervention, had thought the Melfan incapable of doing the work. Right now, he thought grimly, the opposite is true.

  “It is not expected,” Hossantir said gravely, “that you should do everything yourself, Conway.”

  Plainly the Tralthan knew that something was wrong with him- Hossantir’s eyes missed nothing, even when all four of them seemed to be looking in other directions. Conway watched for a few minutes until the team had closed up, then he left Forty-three to check on the progress of the other two patients. Psychologically he felt unwell.

  The organ of absorption had been successfully transplanted into Ten, and Edanelt and his team were busy with the microsurgery required on the replacement limbs. The patient was out of danger, however, because the new organ had been tested with an application of nutrient paint and the sensors showed that it was performing satisfactorily. While he was complimenting the team on its work, Conway stared at the heavy staples which held the edges of the wound together-so closely sutured were they that the wound looked like an enormous zip-fastener. But nothing less would serve to hold an FROB’s hard, thick, and incredibly tough hide together, and the material of the staples was molecularly unstable so that they could be rendered flexible for withdrawal when the healing process was complete.

  But an almost invisible scar, the Hudlar component of Conway’s mind insisted, would be the least of this patient’s problems.

  All at once Conway wanted to run away from all this major surgery and its attendant postoperative problems, instead of having to make yet another examination of a third Hudlar patient.

  Yarrence had concentrated its efforts on the cranial injury, leaving FROB-Three’s abdominal wound to the medics freed by the demise of FROB-Eighteen, while the remaining members of both teams were deployed on the limb amputation and replacement work. It was obvious after the first few minutes that they were engaged in performing a very complex but smooth-running operation.

  From the talk around the frame he gathered that it was also an operation without precedent. To Conway it had seemed to be an obvious solution to FROB-Three’s problem, replacing the missing forelimbs with two from the rear. While not as precise as the originals they would be much more satisfactory in every way than the prosthetics, and there would be no rejection problems. He had read in the old medical texts of Earth-human arm amputees learning to draw, write, and even eat with their feet, and the Hudlar feet were much more adaptable than those of an Earth-human DBDG. But the admiration that simple solution had aroused among the team was making Conway feel embarrassed, because, given the present circumstances, anyone could have thought of it.

  It was the circumstances which were without precedent-the Menelden disaster with its aftermath of massively injured Hudlars requiring transplant surgery together with the ready availability of spare parts. The possibility of one of the transplant cases being able to return to its home planet with the bonus of a pair of forelimbs which were almost as good as the originals was an idea which would have occurred to any moral coward like himself, who dreaded those postop conversations with patients whose transplants were from normal donors rather than from themselves.

  Conway made a mental note to separate FROB-Three from Ten and Forty-three before they returned to consciousness and could begin talking together. The atmosphere between Three and its two less fortunate colleagues would be strained to say the least, and their convalescence would be difficult enough without two of the three being eaten up with envy.

  Consideration of the FROB’s problems had brought his Hudlar component into prominence again, and it was difficult not to sympathize and suffer at the thought of his patient’s postoperative lifestyle. He tried to bring forward the material on the Tralthan, Melfan, and Kelgian components who, as other-species medics, should have been more clinical regarding the situation. But they, too, were overly sympathetic and their responses painful. In desperation he called up the material of Khone, the Gogleskan, who retained its sanity and intelligence by isolating itself from all close contacts with its fellows.

  The Gogleskan material was not at all like that of an ordinary Educator tape. It had more texture, more immediacy, as if another person were truly sharing his mind, however reluctantly. With this degree of understanding between them, he wondered how it would feel to meet and talk to Khone again.

  It was unlikely to happen in the hospital, Conway was sure, because the experience of staying in Sector General would probably drive Khone insane, and O’Mara would never allow it anyway. One of the Chief Psychologist’s strictest rules was that tape donors and carriers must never be allowed to meet because of the psychological trauma, incalculable in its intensity, which would result if two entities of widely different species, but possessing identical personalities, tried to communicate.

  In the light of what had happened to Conway on Goglesk, O’Mara might have to modify that rule.

  And now even the problems of the Gogleskans were clamoring for Conway’s attention, as were the Tralthan, Kelgian, Melfan, and Illensan occupants of his mind. Conway moved back to a position where he could watch the activity around all three operating frames without the team-members being able to see his distress. But the alien babel in his mind was so bad that he could scarcely speak, and it was only with a great effort that he could comment on some aspect of the work or give a word of praise to one of the medics. All at once he wanted out, and to escape from his too-demanding selves.

  With a tremendous effort he guided his alien fingers to the transmit key for his general communication and said carefully, “You people are too good and there is nothing here for me to do. If a problem should arise, call me on the Red Three frequency. There is a matter which I must attend to at once on the methane level.”

  As he was leaving, Hossantir bent an eye-stalk in his direction and said gravely, “Stay cool, Conway.”

  CHAPTER 16

  The ward was cold and dark. Heavy shielding and insulation protected it against the radiation and heat given off by the ship traffic in the vicinity of the hospital, and there were no windows, because even the light which filtered in from the distant stars could not be allowed to penetrate to this level. For this reason the images appearing on his vehicle’s screen had been converted from the nonvisible spectrum which gave the pictures the unreal quality of fantasy, and the scales covering Diagnostician Semlic’s eightlimbed, starfish-shaped body shone coldly through the methane mist like multihued diamonds, making it resemble some wondrous, heraldic beast.

  Conway had often studied pictures and scanner records of the SNLU life-form, but this was the first time he had seen Semlic outside its refrigerated life-support vehicle. In spite of the proven efficiency of Conway’s own insulated vehicle, the Diagnostician was keeping its distance.

  “I come in response to your recent invitation,” Conway said hesitantly, “and to escape from that madhouse up there for a while. I have no intention of examining any of your patients.”

  “Oh, Conway, it’s you inside that thing!” Semlic moved fractionally closer. “My patients will be greatly relieved by your lack of attention. That furna
ce you insist on occupying makes them nervous. But if you would park to the right of the observation gallery, just there, you will be able to see and hear everything that goes on. Have you been here before?”

  “Twice,” Conway replied. “Purely to satisfy my curiosity on both occasions, as well as to enjoy the peace and quiet.”

  Semlic made a sound which did not translate, then said, “Peace and quiet are relative, Conway. You have to turn the sensitivity of your outside microphone right up to hear me with sufficient volume for your translator to be able to handle my input, and I am speaking loudly for an SNLU. To a being like you, who are nearly deaf, it is quiet. I hope that the environment, busy and noisy as it is to me, will help bring the peace and calm which your mind requires so badly.

  “And don’t forget,” it said as it moved away, “turn your sound sensitivity up and your translator off.”

  “Thank you,” Conway said. For a moment the jeweled starfish shape of the Diagnostician aroused in him an almost childlike sense of wonder, so that a sudden wave of emotion misted his eyes and added to the blurring effect of the methane fog filling the ward as he added, “You are a kind, understanding, and warmhearted being.”

  Semlic made another untranslatable sound and said, “There is no need to be insulting …

  For a long time he watched the activity in the busy ward and noticed that a few of the low-temperature nursing staff attending the patients wore lightweight protective suits, indicating that their atmosphere requirements were somewhat different from the ward in general. He saw them doing things to and for their charges which made no sense at all, unless he was to take an SNLU tape, and they worked in the almost total silence of beings with a hypersensitivity to audible vibrations, and at first there was nothing to hear. But the more deeply he concentrated the more aware he became of delicate patterns of sound emerging, of a kind of alien music which was cold and pure and resembled nothing he had ever heard before, and eventually he could distinguish single voices and conversations which were like the cool, passionless, delicate, and ineffably sweet chiming of colliding snowflakes. Gradually the peace and beauty and utter strangeness of it all reached him and the other components of his mind, and gently dissolved away all the stress and conflict and mental confusion.
