"His own tragedy? What do you mean?"
"Well, Callan was a biologist, not an expert in radiation. I don't know exactly what happened. Exposure to X-rays for long periods produces burns, ulcers, malignancies. Maybe Callan didn't take proper precautions to shield his device, or maybe he was using a radiation of peculiarly irritating quality. Anyway, his wife sickened first — an ulcer that turned cancerous.
"He had a radio — a wireless, rather, in 1921 — and he summoned his sloop from the Chathams. It sank off that coral spit, and Callan, growing desperate, succeeded somehow in breaking his wireless. He was no electrician, you see.
"Those were troubled days, after the close of the War. With Callan's sloop sunk, no one knew exactly what had become of him, and after a while he was forgotten. When his wife died, he buried her; but when he died there was no one to bury him. The descendants of what had been his cats took care of him, and that was that."
"Yeah? What about Lilith?"
"Yes," said Carver soberly. "What about her? When I began to suspect the secret of Austin Island, that worried me. Was Lilith really quite human? Was she, too, infected by the taint of variation, so that her children might vary as widely as the offspring of the — cats? She spoke not a word of any language I knew — or I thought so, anyway — and I simply couldn't fit her in. But Callan's diary and notes did it for me."
"How?"
"She's the daughter of the captain of Callan's sloop, whom he rescued when it was wrecked on the coral point. She was five years old then, which makes her almost twenty now. As for language — well, perhaps I should have recognized the few halting words she recalled. C'm on , for instance, was comment — that is, 'how?' And pah bo was simply pas bon , not good. That's what she said about the poisonous fruit. And lay shot was les chats , for somehow she remembered, or sensed, that the creatures from the eastern end were cats.
"About her, for fifteen years, centered the dog creatures, who despite their form were, after all, dogs by nature, and loyal to their mistress. And between the two groups was eternal warfare."
"But are you sure Lilith escaped the taint?"
"Her name's Lucienne," mused Carver, "but I think I prefer Lilith." He smiled at the slim figure clad in a pair of Jameson's trousers and his own shirt, standing there in the stern looking back at Austin. "Yes, I'm sure. When she was cast on the island, Callan had already destroyed the device that had slain his wife and was about to kill him. He wrecked his equipment completely, knowing that in the course of time the freaks he had created were doomed."
"Doomed?"
"Yes. The normal strains, hardened by evolution, are stronger. They're already appearing around the edges of the island, and some day Austin will betray no more peculiarities than any other remote islet. Nature always reclaims her own."
