capable of interstellar travel? The being is a herbivore. It does not even have the fingernails that are the evolutionary legacy of claws, and it appears to be completely defenseless.”
“How about concealed natural weapons?” O’Mara asked. But before Conway could reply, Murchison answered for him.
“No evidence of any, sir,” she said. “I paid particular attention to the furless, brownish area of skin at the base of the spine, since this was the only feature of the being’s physiology that we did not understand. Both male and female cadavers possessed them. They are small mounds or swellings, four to five inches in diameter and composed of dry, porous tissue. They do not secrete anything and give the appearance of a gland or organ that is inactive or has atrophied. The patches were a uniform pale brown color on the adults. The survivor, who is a female adolescent or preadolescent, as far as we can judge, had a pale pink mound, which had been painted to match the coloration of the adult patches.”
“Did you analyze the paint?” asked O’Mara.
“Yes, sir,” said Murchison. “Some of it had already cracked and flaked off, probably at the time the survivor received its injuries, and we removed the rest of it while we were giving the patient a preoperative cleanup before moving it to the hospital. The paint was organically inert and chemically non-toxic. Giving regard to the patient’s age, I assumed that it was a decorative paint applied for cosmetic purposes. Perhaps the young DBPK was trying to appear more adult than it actually was.
“Seems a reasonable assumption,” said O’Mara. “So, we have a beastie with natural vanity and no natural weapons.
Paint, Conway thought suddenly. An idea was stirring at the back of his mind, but he could not make it take form. Something about paint, or the uses of paint, perhaps. Decoration, insulation, protection, warning … That must be it-the coating of inert, nontoxic, harmless paint!
He moved quickly to the instrument rack and withdrew one of the sprayers which a number of e-ts used to coat their manipulators instead of wearing surgical gloves. He tested it briefly, because its actuator had not been designed for DBDG fingers. When he was sure that he could direct the sprayer with accuracy, he moved across to the soft, furry and apparently defenseless DBPK patient.
“What the blazes are you doing, Conway?” asked O’Mara.
“In these circumstances the color of the paint should not worry the patient too much,” Conway said, thinking aloud and ignoring the Chief Psychologist for the moment. He went on, “Prilicla, will you move closer to the patient, please. I feel sure there will be a marked change in its emotional radiation over the next few minutes.”
“I am aware of your feelings, friend Conway,” said Prilicla.
Conway laughed nervously. “In that case, friend Prilicla, I feel fairly sure that I have the answer. But what about the patient’s feelings?”
“Unchanged, friend Conway,” said the empath. “There is a general feeling of concern. It is the same feeling I detected shortly after it regained consciousness and recovered from its initial fear and confusion. There is deep concern, sadness, helplessness and … and guilt. Perhaps it is thinking about its friends who died.”
“Its friends, yes,” said Conway, switching on the sprayer and beginning to paint the bare area above the patient’s tail with the bright red inert pigment. “It is worried about its friends who are alive.”
The paint dried rapidly and set in a strong, flexible film. By the time Conway had finished spraying on a second layer the patient withdrew its head from underneath its furry tail to look at the repainted patch of bare skin; then it turned its face to Conway and regarded him steadily with its two large, soft eyes. Conway restrained an impulse to stroke its head.
Prilicla made an excited trilling noise, which did not translate, then said, “The patient’s emotional radiation shows a marked change, friend Conway. Instead of deep concern and sadness, the predominant emotion is one of intense relief.”
That, thought Conway with great feeling, is my own predominant feeling at the moment. Aloud, he announced, “That’s it, everyone. The contamination emergency is over.”
They were all staring at him, and their feelings were so intense and mixed that Prilicla was clinging to the ceiling and shaking as if caught in an emotional gale. Colonel Skempton’s face had disappeared from the screen, so it was the craggy features of O’Mara alone glaring out at him.
“Conway,” said the Chief Psychologist harshly, “explain.”
He began his explanation by requesting a playback of the sound and vision record of the DBPK’s treatment from the point a few minutes before it fully regained consciousness. While they were watching Thornnastor, the Kelgian theater nurse and the Melfan Edanelt, who had moved back a short distance to check the patient’s air line, Conway said, “The reason why nobody on board the Rhabwar was affected during the trip here was that at no time was the patient conscious. Now, the three attending physicians may or may not be handsome to other members of their respective species, but a being, an immature being at that, confronted with them for the first time might well find them visually quite horrendous. Under the circumstances the patient’s fear and panic reaction are understandable, but pay particular attention to the physical response to what, for a few seconds, it regarded as a physical threat.
“The eyes opened wide,” he continued as the scene unfolded on the main screen, “the body stiffened and the chest expanded. A fairly normal reaction, you’ll agree. An initial moment of paralysis followed by hyperventilation so that as much oxygen as possible is available in the lungs either to scream for help or to drive the muscles for a quick getaway. But our attention was concentrated on what was happening to the three attending physicians and the affected team-member, so that we did not notice that the patient’s chest remained expanded for several minutes, that it was, in fact, holding its breath.”
On the screen Thornnastor toppled heavily to the floor, the Kelgian nurse collapsed into a limp heap of fur, Edanelt’s bony undershell clicked loudly against the floor, the transfer team-member also collapsed and everyone else who was unprotected headed for the pressure litter or the breathing masks. “The effects of this socalled bug,” Conway went on, “were sudden and dramatic. Respiratory failure or partial failure and collapse, and clear indications that the voluntary and involuntary muscle systems had been affected. But there was no rise in body temperature, which would be expected if the beings concerned were fighting an infection. If infection is ruled out, then the DBPK life-form was not as defenseless as it looked …”
To be the dominant life-form on its planet, the DBPKs had to have some means of defending themselves, Conway explained. Or more accurately, the beings who really needed it had a means of defense. Probably the adult DBPKs were mentally agile enough to avoid trouble and to protect their young when they were small and easily carried. But when the children grew too large for their parents to protect and were as yet too inexperienced to protect themselves, they had evolved a means of defense that was effective against everything that lived and breathed.
When threatened by natural enemies, the young DBPKs released a gas-which resembled in its effects the old Earth-snake venom curare, with the rapidity of action of some of the later nerve gases- so that the enemy’s breathing stopped and it was no longer a threat. But it was a two-edged weapon in that it was capable of knocking out everything that breathed oxygen, including the DBPKs themselves. However, the event that triggered the release of the gas also caused the being concerned to hold its breath, which indicated that the toxic material had a complex and unstable molecular structure that broke down and became harmless within a few moments of release, although by that time the natural enemy was no longer a threat.
“With the rise of civilization and the coming of cities, leading to large numbers of the beings of all age groups living closely together, the defense mechanism of the DBPK children became a dangerous embarrassment. A suddenly frightened child, reacting instinctively, could inadvertently kill members of its own family, passers-by in the street or classmates in school. So the organ that released the gas was painted over and sealed until the child reached maturity and the organ became inactive.” There were probably psychological or sociological reasons, Conway thought, why the active organs were painted to resemble those of a ‘safe’ adult.
“But the patient is a preadolescent of a race that has star travel, and it would expect to see alien life forms,” Conway continued, turning away from the screen as the recording flicked off. “It reacted instinctively because of weakness and physical injury, and almost immediately realized what it had done. Judging by Prilicla’s emotion readings, it felt guilty; was desperately sorry for what it had done to some of the friends who had rescued it, and was helpless because it could not warn us of the continuing danger. Now it has been rendered safe again and it is relieved, and judging by its emotional reaction to this situation, I would say that these are nice people—”
Conway broke off as the screen lit again to show the faces of both Colonel Skempton and Major O’Mara.
