“How?”

Moru stood waiting while the language he did not understand went to and fro around him.

“I’m no medic.” Jonafer kept his 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 want this means, I suppose,” Jonafer said. “There’ll be no problem to ending the practice. We’ll simply tell 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 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.

“What?” His question was a reflexive noise.

“After I learned about the dipteroid phenomenon,” she said. “All that was necessary was for me to keep silent. Moru, his children, his entire race would go on being prey for centuries, maybe forever. I sat for half an hour, I think, having my revenge.”

“And then?” Jonafer asked.

“I was satisfied and could start thinking about justice,” Evalyth said.

She drew a knife. Moru straightened his back. She stepped behind him and cut his bonds. “Go home,” she said. “Remember him.”
