angle.”
“How?” the medic would have replied. “You’re a general biologist. No reflection on you, but detailed human physiology is out of your line.”
“Um-m-m… yes and no. My main job is studying species of terrestrial origin and how they’ve adapted to new planets. By a remarkable coincidence, man is included among them.”
But Donli was gone, and no one else was competent to do his work—to be any part of him, but she fled from that thought and from the thought of what she must presently do. She held her mind tightly to the realization that one of Uden’s team had tried to apply Donli’s knowledge. As Jonafer remarked, a living Donli might well have suggested an idea, unorthodox and insightful, that would have led to the discovery of whatever was there to be discovered, if anything was. Uden and his assistants were routineers. They hadn’t even thought to make Donli’s computer ransack its data banks for possibly relevant information. Why should they, when they saw their problem as strictly medical? And, to be sure, they were not cruel. The anguish they were inflicting had made them avoid whatever might lead to ideas demanding further research. Donli would have approached the entire business differently from the outset.
Suddenly the gloom thickened. Evalyth fought for breath. Too hot and silent here; too long a wait; she must do something or her will would desert her and she would be unable to squeeze the trigger.
She stumbled to her feet and into the lab. The fluoro blinded her for a moment when she turned it on. She went to his computer and said: “Activate!”
Nothing responded but the indicator light. The windows were totally black. Clouds outside shut off moon and stars.
“What—” The sound was a curious croak. But that brought a releasing gall:
“Matters of that nature are presumably best explained in terms of psychology and cultural anthropology,” said the voice.
“M-m-maybe,” Evalyth said. “And maybe not.” She marshalled a few thoughts and stood them firm amidst the others roiling in her skull.
“The inhabitants could be degenerate somehow, not really human.”
The machine hummed. Evalyth closed her eyes and clung to the edge of the desk.
At the other end of forever, the voice came to her:
“The sole behavioral element which appears to be not easily explicable by postulates concerning environment and accidental historical developments, is the cannibalistic puberty rite. According to the anthropological computer, this might well have originated as a form of human sacrifice. But that computer notes certain illogicalities in the idea, as follows.
“On Old Earth, sacrificial religion was normally associated with agricultural societies, which were more vitally dependent on continued fertility and good weather than hunters. Even for them, the offering of humans proved disadvantageous in the long run, as the Aztec example most clearly demonstrates. Lokon has rationalized the practice to a degree, making it a part of the slavery system and thus minimizing its impact on the generality. But for the lowlanders it is a powerful evil, a source of perpetual danger, a diversion of effort and resources that are badly needed for survival. It is not plausible that the custom, if ever imitated from Lokon, should persist among every one of those tribes. Nevertheless it does. Therefore it must have some value and the problem is to find what.
“The method of obtaining victims varies widely, but the requirement always appears to be the same. According to the Lokonese, one adult male body is necessary and sufficient for the maturation of four boys. The killer of Donli Sairn was unable to carry off the entire corpse. What he did take of it is suggestive.
“Hence a dipteroid phenomenon may have appeared in man on this planet. Such a thing is unknown among higher animals elsewhere, but is conceivable. A modification of the Y chromosome would produce it. The test for that modification, and thus the test of the hypothesis, is easily made.”
The voice stopped. Evalyth heard the blood slugging in her veins. “What are you talking about?”
“The phenomenon is found among lower animals on several worlds,” the computer told her.
“It is uncommon and so is not widely known. The name derives from the Diptera, a type of dung fly on Old Earth.”
Lightning flickered. “Dung fly—good, yes!”
The machine went on to explain.
Jonafer came along with Moru. The savage’s hands were tied behind his back, and the spaceman loomed enormous over him. Despite that and the bruises he had inflicted on himself, he hobbled along steadily. The clouds were breaking and the moon shone ice-white. Where Evalyth waited, outside her door, she saw the compound reach bare to the saw-topped stockade and a crane stand above like a gibbet. The air was growing cold—the planet spinning toward an autumn—and a small wind had arisen to whimper behind the dust devils that stirred across the earth. Jonafer’s footfalls rang loud.
He noticed her and stopped. Moru did likewise. “What did they learn?” she asked.
The captain nodded. “Uden got right to work when you called,” he said. “The test is more complicated than your computer suggested—but then, it’s for Donli’s kind of skill, not Uden’s. He’d never have thought of it unassisted. Yes, the notion is true.”
“How?”
Moru stood waiting while the language he did not understand went to and fro around him.
“I’m no medic.” Jonafer kept his tone altogether colorless. “But from what Uden told me, the chromosome defect means that the male gonads here can’t mature spontaneously. They need an extra supply of hormones—he mentioned testosterone and androsterone, I forget what else—to start off the series of changes which bring on puberty. Lacking that, you’ll get eunuchism. Uden thinks the surviving population was tiny after the colony was bombed out, and so poor that it resorted to cannibalism for bare survival, the first generation or two. Under those circumstances, a mutation that would otherwise have eliminated itself got established and spread to every descendant.”
Evalyth nodded. “I see.”
“You understand what this means, I suppose,” Jonafer said. “There’ll be no problem to ending the practice. We’ll simply tell them we have a new and better Holy Food, and prove it with a few pills. Terrestrial-type meat animals can be reintroduced later and supply what’s necessary. In the end, no doubt our geneticists can repair that faulty Y chromosome.”
He could not stay contained any longer. His mouth opened, a gash across his half-seen face, and he rasped: “I should praise you for saving a whole people. I can’t. Get your business over with, will you?”
Evalyth trod forward to stand before Moru. He shivered but met her eyes. Astonished, she said: “You haven’t drugged him.”
“No,” Jonafer said. “I wouldn’t help you.” He spat.
“Well, I’m glad.” She addressed Moru in his own language: “You killed my man. Is it right that I should kill you?”
“It is right,” he answered, almost as levelly as she. “I thank you that my woman and my sons are to go free.” He was quiet for a second or two. “I have heard that your folk can preserve food for years without it rotting. I would be glad if you kept my body to give to your sons.”
“Mine will not need it,” Evalyth said. “Nor will the sons of your sons.”
Anxiety tinged his words: “Do you know why I slew your man? He was kind to me, and like a god. But I am lame. I saw no other way to get what my sons must have; and they must have it soon, or it would be too late and they could never become men.”
“He taught me,” Evalyth said, “how much it is to be a man.”
She turned to Jonafer, who stood tense and puzzled. “I had my revenge,” she said in Donli’s tongue.
