Code Blue Emergency

CHAPTER 4

The lecturer was a Nidian who had been introduced as Senior Physician Cresk-Sar. While it was speaking, it prowled up and down the line of trainees like some small, hairy, carnivorous beast, which meant that every few minutes it passed Cha Thrat so closely that she wanted to either fold her limbs in defensive mode or run away.

“To minimize verbal confusion during meetings with other-species entities,” it was saying, “and to avoid in-advertently giving offense, it is assumed that all members of the medical and support staff who do not belong to your own particular species are sexless. Whether you are addressing them directly or discussing them in their absence, you will always think of them as an ’it’. The only exception to this rule is when an other-species patient is being treated for a condition directly related to its sex, in which case the doctor must know whether it is male or female, or one of the multisexed species, if the proper treatment is to be carried out.

“I am a male Nidian DBDG,” Cresk-Sar went on, “but do not think of me as ‘he’ or ‘him’. Think of me as ‘it’.”

As the disgusting, hairy shape moved to within a few paces of her before turning away again, Cha Thrat thought that she would have no difficulty in thinking of this Senior Physician as “it.”

With the intention of finding someone less repulsive to look at, she turned her eyes toward the trainee closest to her — one of the three silver-furred Kelgians attending the lecture. It was strange, she thought, how the Ni-dian’s fur made her cringe inwardly while the equally alien covering of the Kelgian relaxed and calmed her like a work of great art. The fur was in constant motion, with long, slow ripples moving from the creature’s conical head right down to its tail, with occasional cross-eddies and wavelets appearing, as if the incredibly fine pelt was a liquid stirred by an unfelt wind. At first she thought the movements were random, but a pattern of ripples and eddies seemed to be developing the more closely shewatched.

“What are you staring at?” the Kelgian said suddenly, its translated words overlaid by the moaning and hissing sounds of its native speech. “Do I have a bald patch, or something?”

“I’m sorry, I had not meant to give offense,” Cha Thrat said. “Your fur is beautiful and I couldn’t help admiring it the way it moves—”

“Pay attention, you two!” the Senior Physician saidj sharply. It moved closer, looked up at each of them in turn, then went prowling down the line again.

“Cresk-Sar’s fur,” the Kelgian said softly, “is a sight. It makes me think that invisible and no doubt imaginary parasites are about to change their abode. It gives me a terrible psychosomatic itch.”

This time Cresk-Sar gave them another long look, made an irritated, snuffling sound that did aot translate, and continued with what it was saying.

“… There is a great deal of illogical behavior associated with sexual differences,” it went on, “and I must emphasize once again, unless the sex of a particular entity has a direct bearing on its course of treatment, the subject must be ignored if not deliberately avoided. Some of you may consider that such knowledge of another species would be helpful, conversationally useful during off-duty meetings or, as often happens in this place, when a particularly interesting piece of gossip is circulating. But believe me, in this area, ignorance is a virtue.”

“Surely,” said a Melfan trainee halfway down the line, “there are interspecies social occasions, shared meals or lectures, when it would be a gross act of bad manners to ignore another intelligent and socially aware person’s gender. I think that—”

“And I think,” Cresk-Sar said with a bark, or laugh, “that you are what our Earth-human friends call a gentleman. You haven’t been listening. Ignore the difference. Consider everyone who is not of your own species as neuter. In any case, you would have to observe some of our other-species people very closely to tell the differ-ence, and that in itself could cause serious embarrassment. In the case of Hudlar life-mates, who alternate between male and female mode, the behavior patterns are quite complex.”

“What would happen,” the Keigian beside her said, “if they should go, completely or partly, out of synchronization?”

From the line of trainees there were a number of different sounds, none of which registered on her translator. The Senior Physician was looking at the Kelgian, whose fur, for some reason, had begun to move in rapid, irregular ripples.

“I shall treat that as a serious question,” Cresk-Sar said, “although I doubt that it was intended as such. Rather than answer it myself, I shall ask one of you to do so. Would the Hudlar trainee please step forward.” So that, Cha Thrat thought, is a Hudlar. It was a squat, heavy life-form with a hard, almost featureless dark-gray skin, discolored by patches of the dried paint she had seen it spraying on itself before they had entered the lecture theater, and she had decided then that it was extremely careless in its application of cosmetics. The body was supported on six heavy tentacles, each of which terminated in a cluster of flexible digits, curled inward so that the weight was borne on heavy knuckles and the fingers remained clear of the floor.

There were no body openings that she could see, not even in the head, which contained eyes protected by hard, transparent shells and a semicircular membrane that vibrated to produce the creature’s words as it turned toward them.

“It is very simple, respected colleagues,” the Hudlar said. “While I am presently male, Hudlars are all sexually neutral until puberty, after which the direction taken is dependent on social-environmental influences,sometimes quite subtle influences that do not involva body contact. A picture of an attractive male-mode Hudi lar might impel one from neuter toward female mode, or the other way around. A conscious choice can be made if the career one intends to follow favors a particular sex. Unless one is mated, the postpuberty sex choice is fixed for the remainder of one’s life.

“When two adults become life-mates,” the Hudlar went on, “that is, when they join for the purpose of becoming parents and not simply for temporary pleasure, the sex changes are initiated shortly after conception. By the time the child is born the male has become much less aggressive, more attentive and emotionally oriented ward its mate, while its mate is beginning to lose the female characteristics. Following parturition, the process continues, with the father-that-was taking responsibility for the child while progressing to full female mode, and the mother develops all the male characteristics that will enable it to be a father-to-be.

“There is, of course, a time during which both life-mates are emotional neuters,” the Hudlar added, “but this is a period of the pregnancy when physical coupling is contraindicated.”

“Thank you,” the Senior Physician said, but held up a small, hairy hand to indicate that the Hudlar should remain where it was. “Any further comments, questions?”

It was looking at the Kelgian beside her, the one who had asked the original question, but Cha Thrat spoke on impulse.

“It seems to me that the Hudlars are fortunate,” she said, “in that they are not troubled by the situation of the members of one sex considering themselves innately superior to the other, as is the case on Sommaradva …

“And on too many other worlds of the Federation,” the Kelgian interjected, the fur rising into tufts behind itshead.

“… I thank the Hudlar for its explanation,” Cha Thratwent on, “but I was surprised to find that it is presently a male. My first thought, based on observation of what I mistakenly assumed to be cosmetic paint on its body, was that it was female.”

The Hudlar’s speaking membrane began to vibrate, but Cresk-Sar held its hand up for silence and said, “What are your second thoughts?”

Confused, she stared at the hairy little creature, wondering what she was expected to say.

“Come, come,” Cresk-Sar barked. “Tell us what other thoughts, observations, assumptions, mistaken or otherwise, have been going through your Sommaradvan mind regarding this life-form. Think and speak clearly.”

Cha Thrat turned all her eyes on it in a way that, had it been a Sommaradvan, would have elicited an immediate verbal and physical response. She said, “My first thoughts were as described. My second was that it might be Hudlar males rather than females, or perhaps both, who wear decorative paint. Then I observed that the being’s movements were careful, as if it was afraid of injuring nearby people and equipment, the movements of a gentle being of immense physical strength. That taken in conjunction with the low, squat form of the body, with six rather than two or four limbs, suggested that it was a native of a dense, heavy-gravity world with comparable atmospheric pressure, where an accidental fall would be damaging. The very hard but flexible skin, which is unbroken by any permanent body orifices for the intake or elimination of food, suggested that the paint which I had observed the Hudlar spraying onto itself might be a nutrient solution.”

The eyes of Cresk-Sar, and the variegated visual sen-sors of the other trainees, were watching her steadily. Nobody spoke.

Hesitantly she added, “Another thought, wonderful and exciting but, I expect, pure supposition, is that if this heavy-gravity, high-pressure creature can live unprotected in the hospital surroundings, its body must be capable of containing its own very high internal pressures, and an even lower pressure environment should not inconvenience it …

“It might be possible,” she went on, expecting a storm of ridicule from the Nidian Senior, “for it to work unprotected in space. This would mean that—”

“At any moment,” Cresk-Sar said, holding its hand up, “you will give me its physiological classification coding, even though we haven’t covered that yet. Is this the first time you’ve seen a Hudlar?”

“I saw two of them in the dining hall,” she replied, “but at the time I was too confused to know what I was seeing.”

“May your confusion continue to diminish, Cha Thrat,” Cresk-Sar said. Turning its head toward the others, it went on, “This trainee has displayed the qualities of observation and deduction that, when trained and refined, will enable you to live among, understand, and. treat your other-species colleagues and patients. However, I would advise you not to think of a particular life-form as a Nidian, a Hudlar, a Kelgian, a Melfan, or a I Sommaradvan, that is, by their planets of origin, but by their physiological classifications, DBDG, FROB, DBLF, ELNT, or DCNF. That way you will always be; reminded of their pressure, gravity, and atmosphere requirements, basic metabolism and other physiological needs, and know immediately when there is a potential environmental threat to them or to yourselves.”

It continued, “Should a PVSJ, a chlorine-breathingnative of Illensa, accidentally rupture its pressure envelope, the risk to the being concerned and to any oxygen-breathing D, E, and F prefixes in the vicinity would be extreme. And, if you are ever called to a space rescue situation, there may be times when an urgent and accurate identification of the casualty’s physiological classification, and therefore its life-support requirements, may depend on a single limb or small area of body surface glimpsed under shifting wreckage.

“You must train yourselves to be aware, instinctively, of all the differences of the people around you,” Cresk-Sar went on, giving a low laugh-bark, “if only to know whom it is safe to jostle in the corridors. And now I will take you to the wards for your initial patient experience before my next class in—”

“What about the classification system?” said the silver-furred Kelgian — the DBLF, Cha Thrat corrected herself — beside her. “If it is as important as you say it is, surely you are lacking in the qualities of a teacher not to have explained it to us.”

Cresk-Sar walked slowly toward the speaker, and she wondered if she could possibly reduce the verbal violence to come by asking the Senior Physician another and more politely worded question. But for some reason the Nidian completely ignored the DBLF and spoke instead to Cha Thrat.

“You will already have observed,” it said, “that these Kelgian DBLF life-forms are outspoken, ill-mannered, rude, and completely lacking in tact …”

You should talk, Cha Thrat thought.

“… But there are good psychophysiological reasons for this,” it went on. “Because of inadequacies in the Kelgian speech organs, their spoken language lacks modulation, inflection, and all emotional expression. But they are compensated by their highly mobile fur that acts, so far as another Kelgian is concerned, as a perfect but uncontrollable mirror to the speaker’s emotional state. As a result the concept of lying, of being diplomatic, tactful, or even polite is completely alien to them. A DBLF says exactly what it means or feels, because the fur reveals its feelings from moment to moment and to do otherwise would be sheer stupidity. The opposite also holds true, because politeness and the verbal circumlocution used by many species confuses and irritates them.

“You will find some of the personalities here as alien as the persons,” it continued. “Considering the fact that you have met only one other-species being before your arrival here, your behavior today makes me sure that you will have not trouble in adapting to—”

“Teacher’s pet,” the DBLF said, its fur tufting into spikes. “I was the one who asked the question, remember?”

“That you did,” Cresk-Sar replied, looking at the wall chronometer. “Tapes covering the life-form physiological classification system will be sent to your quarters sometime today. You must study the visual material they con- | tain, carefully and repeatedly, and use your translators on the spoken commentary. But now I have time only to outline the basics of the system.”

It turned suddenly and resumed its place facing them, > Plainly the answer to the question was being directed,! toward everyone.

“Unless you have already been attached to one of the smaller, multienvironment hospitals,” Cresk-Sar said, “you will normally have encountered off-world patients one species at a time, probably on a short-term basis as a result of a ship accident, and you would refer to them by their planets of origin. But I must stress once again, the rapid and accurate identification of incoming patients isvital, because all too often they are in no condition to furnish the necessary physiological data themselves. Here we have evolved a basic, four-letter physiological classification system that enables us to provide the required life-support and initial treatment pending a more detailed investigation, if that should be necessary, by Pathology. It works like this.

“The first letter denotes the level of physical evolution reached by the species when it acquired intelligence,” it continued. “The second indicates the type and distribution of limbs, sense organs, and body orifices, and the remaining two letters refer to the combination of metabolism and food and air requirements associated with the home planet’s gravity and atmospheric pressure, which in turn gives an indication of the physical mass and protective tegument possessed by the being.”

Cresk-Sar barked softly before saying “Usually I have to remind our other-species trainees at this point that the initial letter of their classification should not be allowed to give them feelings of inferiority, because the degree of physical evolution is controlled by environmental factors and bears little relation to the degree of intelligence …”

Species with the prefix A, B, or C, it went on to explain, were water-breathers. On most worlds, life had originated in the sea, and these beings had developed intelligence without having to leave it. D through F were warm-blooded oxygen-breathers, into which group most of the intelligent races of the Federation fell, and the G and K types were also oxygen breathing, but insectile. The Ls and Ms were light-gravity, winged beings.

Chlorine-breathing life-forms were contained in the O and P groups, and after these came the more exotic, the more highly evolved physically, and the downright weird types. Into these categories fell the radiation-eaters, the ultra-cold-blooded or crystalline beings, and entities ca-pable of modifying their physical structure at will. However, those beings possessing extrasensory powers, telekinesis, or teleportation sufficiently well developed to make ambulatory or manipulatory appendages unnecessary were given the prefix V regardless of their size, shape, or environmental background.

’There are anomalies in the system,” the Senior Physician continued, “and these must be bjamed on the lack of imagination and foresight of the originator. The AACP life-form, for example, has a vegetable metabolism. Normally the A prefix denotes a water-breather, there being nothing lower on our evolutionary coding scale than the piscatorial life-forms. But the double-A prefix, the AACPs, are mobile, intelligent vegetables, and plant life evolved before the fish.

“And now,” it said, looking at the chronometer again, “you will meet some of these weird and wonderful and perhaps horrifying creatures. It is the hospital’s policy to give you the earliest possible opportunity of getting to know and work with the patients and staff members. Regardless of your position or seniority in your home-planet hospitals, your rank here will be that of Junior or Trainee Nurse — until, that is, you can convince me that your professional competence warrants a higher rating.

“I am not easy to convince,” Cresk-Sar added as it began moving toward the exit. “Follow me, please.”

It was not easy to follow the Senior Physician because it moved fast for such a small being, and Cha Thrat had the feeling that the other trainees were more experienced in navigating the hospital corridors than she was. But then she noticed that the Hudlar — the FROB — was falling behind as well.

“For obvious reasons,” the FROB said as they drew level, “the people here give me plenty of room. If youwere to stay directly behind me, together we might significantly increase our speed.”

She had a sudden and shocking feeling of unreality, as if she had been plunged into a nightmare world that was both terrifying and wonderful, a world in which courtesy was being shown by a horrendous beast that was capable of tearing her apart without straining a muscle on one of its six tentacles. But even if this were a dream, the proper response had to be made.

“You are most considerate,” she said. “Thank you.” The being’s membrane vibrated but the sound did not translate. Then it said, “About the nutrient paint you noticed earlier, to complete your information and to show how close your deductions were to the actuality, the paint is not necessary at home. There the atmosphere is so dense and thickly packed with edible, floating organisms that it resembles a semiliquid soup, a food source that, because of our high metabolic rate, is absorbed continuously. As you can see, the last paint application has almost disappeared and is due for renewal.”

Before she could reply, one of the Kelgian DBLFs fell back and said, “I was nearly walked on by a Tralthan just now. This looks like a good idea. There’s room for one more.”

It moved closer to Cha Thrat so that they were both protected by the Hudlar’s massive body. Choosing her words carefully, she said, “I do not wish to give offense, but I cannot tell the difference between one Kelgian and another. Are you the DBLF whose fur I was admiring during the lecture?”

“Admiring, you used the right word!” the Kelgiansaid, its fur running in concentric waves from head totail. “Don’t worry about it. If we had more than oneSommaradvan, I couldn’t tell the difference either.”

Suddenly the Hudlar stopped and, looking past itsspeaking membrane, she saw why. The whole group ofl trainees had halted and Cresk-Sar was beckoning to af Melfan and the other two Kelgians.

“This is a Tralthan post-op recovery ward,” it said.l You two will report here after lectures every day until] instructed otherwise. You don’t need protective suits, the air is breathable, and trace quantities of Tralthan) body odor should be ignored. Go in, you’re expected.”

When the party was on its way again she noticed aJ few of the trainees detaching themselves without being told, and assumed that they had joined the class earlier and had already been assigned wards. One of them was her Hudlar crowd controller. Very soon the group had shrunk until there was only the DBLF and herself left, and Cresk-Sar was pointing at the Kelgian.

“This is a PVSJ medical ward,” it said briskly. “You will be met inside the lock antechamber and instructed in the use of your protective envelope before going through. You will then—”

“But they’re chlorine-breathers in there!” the Kelgian protested, its fur standing out in spikes. “Can’t you give me a ward where I can at least breathe the air? Do you try to make it as difficult as possible for the new people? What happens if I accidentally rupture my suit?”

“To answer your questions in turn,” the Senior Physician replied, “No. You’ve discovered that. And the nearby patients would have their existing injuries complicated by oxygen contamination.”

“What about me, stupid?”

“You,” Cresk-Sar said, “would suffer chlorine poisoning. And what the Charge Nurse would do to you if you recovered doesn’t bear thinking about.”

She had to concentrate so hard on keeping pace with the Senior Physician as they descended three levels, and traversed seemingly endless and overpopulated corri-dors, that there was no chance to ask what she would be expected to do. But then Cresk-Sar stopped at an enormous lock entrance that was visually identified in the Galactic Federation’s principal written languages — but which did not, of course, include Sommaradvan — and answered the unasked question.

“This is the hospital’s AUGL ward,” it said. “You will find that the patients, all natives of the ocean work! of Chalderescol, are among the most visually fearsome beings you are ever likely to encounter. But they are harmless so long as you—”

“The A prefix” Cha Thrat broke in urgently, “denotes water-breathers.”

“Correct,” the Nidian said. “What’s wrong? Is there a problem O’Mara didn’t tell me about? Are you uncomfortable or afraid in water?”

“No,” Cha Thrat said. “1 enjoy swimming, on the surface. The problem is my lack of a protective garment.”

Cresk-Sar barked and said, “There is no problem. The more complex protective equipment for heavy-gravity, high-pressure, and elevated temperature work needs time to produce, but a simple, water-impermeable, contoured envelope with air and communication systems is an easy job for the fabricator. Your suit is waiting for youinside.”

This time the Senior Physician went with her, explaining that, as she was a new life-form to the hospital, it had to ensure that her equipment functioned properly and comfortably. But in the event, it was the being waiting for them in the lock antechamber who immediately took charge and did all the talking.

“Cha Thrat,” it said briskly, “I am Charge Nurse Hredlichli, a PVSJ. Your protective envelope is in two pieces. Climb into the lower half, pulling on one leg at a time, in whichever order you find most convenient,using the heavier arms encircling your waist. Use the same four arms to pull on the top half, inserting the head; and four shoulder-mounted arms first. You will think that the limb end-sections are small, but this is to ensure a tight fit and maximum sensitivity for the digits. Don’t seal the waist joint until you know that your air supply is working. When you are sealed in, I’d show you the systems checks that must be performed at every dressing. Then you will remove the envelope and put it on again, repeating the process until we are both happy with your performance. Please begin.”

Hredlichli circled her, giving advice and directions during the first three dressings, and then seemed to ignore her while it talked to the Senior Physician. The spiney, membraneous body, looking like a haphazard collection of oily, unhealthy vegetation, was obscured by the yellow chlorine fog inside the being’s protective envelope. It was impossible to tell where the Charge Nurse’s attention was directed, because Cha Thrat had been unable to locate its eyes.

“We are seriously understaffed at present,” Hredlichli was saying, “with three of my best nurses on special post-op recovery cases to the exclusion of all else. Are you hungry?”

Cha Thrat felt that the question was for her, but was unsure of the type of answer to give — the subservient, self-negating reply expected by a ruler or the accurate, truthful kind due a warrior-level colleague. Ignorant as she was of Hredlichli’s exact status, she did her best to combine the two.

“I am hungry,” she replied, using the opportunity to test her suit’s communicator, “but the condition is not yet so advanced that it would impair me physically.”

“Good!” said Hredlichli. “As a junior-in-training you will soon discover that practically everyone and every-thing takes precedence over you. If this causes emotional tension, which may be expressed as verbal resentment or anger, try not to release it until you are out of my ward. You will be allowed to visit your dining hall, for a strictly limited period, as soon as someone returns to relieve you. And now I think you know how your suit works …”

Cresk-Sar turned toward the entrance. Lifting one tiny, hairy hand, it said, “Good luck, Cha Thrat.”

“… So we’ll go inside to the Nurses’ Station,” it went on, seeming to ignore the departing Nidian. “Double-check your suit seals and follow me.”

She found herself in a surprisingly small compartment that had one transparent wall giving a view into a dim green world where the difference between the inhabitants and the decorative vegetation designed to make them feel at home was unclear. The other three sides of the room were covered by storage units, monitor screens, and equipment whose purpose she could not even guess at. The entire ceiling was devoted to brightly colored signs and geometrical shapes.

“We have a very good staff and patient safety record in this ward,” the Charge Nurse went on, “and I don’t want you to spoil it. Should you damage your suit and be in danger of drowning, however, mouth-to-mouth resuscitation is not advisable between oxygen- and chlorine-breathers, so you must move quickly to one of the emergency air chambers marked so" — she indicated one of the ceiling designs—"and await rescue. But the accident, or should I say the serious inconvenience, that you must guard against is pollution by patient body wastes. Filtration or replacement of the water volume in a ward this size is a major maintenance operation that would hamper our work and get us talked about in derogatory fashion all over the hospital.”

“I understand,” Cha Thrat said.

Why had she come to this awful place, she wondered,] and could she justify to herself her immediate resignation? In spite of the warnings from O’Mara and Cresk-Sar that she would be starting at the lowest level, this was not work for a Sommaradvan warrior-surgeon. If word of what she was expected to do were to get back to her erstwhile colleagues, she would be forced into the life of a recluse. But these people were not likely to tell her people about it because, to them, such activities were so commonplace as to be unworthy of mention. Perhaps she would be found unsuitable or incompetent and dismissed from the hospital with this demeaning and unpleasant episode secret and her honor intact. But she was dreading what was coming next.

But it was not nearly as bad as she had expected.

“The patients usually know in advance when they need to evacuate,” Hredlichli went on, “and will call the nurse with time to spare. Should you be called for this purpose, the equipment you require is stored in the compartment with its door marked like this.” A frondlike arm appeared inside its protective envelope, pointing to another distinctively marked panel on the ceiling, then to its distant, brightly lit twin that shone through the green dimness of,the ward. It went on, “But don’t worry, the patient will know all about the operation of the equipment and will prefer to help itself. Most of them dislike using the thing, you’ll find that Chalders embarrass easily, and any who are not immobilized will prefer to use the room marked with that symbol. It is a long, narrow compartment barely large enough to contain one Chalder and is operated by the user. Extraction and filtration of the wastes is automatic, and if anything goes wrong it is a Maintenance problem.”

Hredlichli’s appendage rose again to point toward theconfusion of shapes at the other end of the ward. “If you need help with a patient, ask Nurse Towan. Most of its time is being spent with a seriously ill patient, so don’t distract it unnecessarily. Later today I shall instruct you on the Chalder optimum pulse rate, pressure, and body temperature, and how and where to obtain them. The vital signs are taken and recorded at regular intervals, the frequency depending on the condition of the patient. You will also be shown how to sterilize and dress surgical wounds, which is not a simple job on a water-breather, and in a few days you may be allowed to do it yourself. But first you must get to know your patients.”

The appendage was pointing at a doorless opening into the main ward. A sudden paralysis seemed to be affecting all twelve of Cha Thrat’s limbs, and she tried desperately to delay any movement by asking questions. “Nurse Towan,” she said. “What species is it?” “An AMSL,” the Charge Nurse replied. “A Creppel-lian octopoid, and Sector General qualified, so you have nothing to worry about. The patients know that we are being assigned a new-species trainee and are expecting you. Your body configuration is well suited to the water medium, so I suggest that you go in and begin by teaching yourself how to move about the ward.”

“Please, a further question,” Cha Thrat said desperately. “The AMSL is a water-breather. Why aren’t all of the medical attendants here water-breathers? Wouldn’t it be simpler if they were Chalders, the same species astheir patients?”

“You haven’t even met a patient and already you’re trying to reorganize the ward!” Hredlichli said, producing another appendage from somewhere and gesticulating with them both. “There are two reasons why we don’t do as you suggest. One is that very large patients can be effectively treated by small medics, and SectorGeneral was designed with precisely that situation in mind. The second is structural. Personnel accommodation and recreation space is at a premium here, and can you imagine how much of it would be taken up by the life-support requirements of, say, a basic medical and nursing staff of one hundred water-breathing Chalders?" But enough of this,” the Charge Nurse said impatiently. “Go into the ward and act as if you know what you’re doing. We’ll talk later. If I don’t go for lunch this instant, they’ll find me in a corridor dead from malnutrition …”

It seemed like a very long time before she was able to venture into the green immensity of the ward, and then she swam only as far as a structural support less than five body-lengths from the entrance. The harsh, angular contours of the metal had been visually softened by irregular areas of paint and the attachment of artificial foliage, Cha Thrat saw as she swam around it, no doubt to make it resemble the vegetation of the home world.

Hredlichli had been right; she was able to adapt quickly to movement in water. When she kicked out with her feet and simultaneously swept the four mid-arms downward, she spurted forward and coasted for three body-lengths. When one or two of the mid-arms were held steady and the hands angled, quite delicate directional and positional control was possible. Previously she had never been able to remain under water for more than a few moments, and she was beginning to really enjoy the sensation. She continued to circle the structural member, moving up and down its entire length and examining the artificial vegetation even more closely. There were clusters of what could have been underwater fruit, which glowed with multihued light at her approach, revealing themselves to be a part of the ward lighting system. But the pleasures of discovery were short-lived.

One of the long, dark-green, motionless shadows lying along the floor of the ward had detached itself and was rushing silently toward her. It slowed, took monstrous, terrifying, three-dimensional form and began to circle her slowly as she had been circling the structuralsupport.

The creature was like an enormous, armored fish with a heavy, knife-edged tail, a seemingly haphazard arrangement of stubby fins, and a thick ring of ribbon tentacles projecting from the few gaps in its organic body-armor. The tentacles lay flat along its sides when it was moving forward, but they were long enough to reach beyond the thick, blunt wedge of the head. One tiny, lidless eye watched her as it circled closer.

Suddenly the head divided to reveal a vast pink cavern of a mouth edged with row upon row of enormous white teeth. It drifted closer, so that she could even see the periodic fogging of the water around its gills. The mouth opened even wider. “Hello, Nurse,” it said shyly.
