Carver lighted his pipe, set about building a fire of the plentiful driftwood, and prepared for the night. He delivered himself of a few choice epithets descriptive of the two Maoris as he realized that his comfortable sleeping bag was gone with the proa, but the fire would serve against the chill of the high Southern latitude. He puffed his pipe reflectively to its end, lay down near his driftwood blaze, and prepared to sleep.

When, seven hours and fifty minutes later, the edge of the sun dented the eastern horizon, he was ready to admit that the night was something other than a success. He was hardened to the tiny, persistent fleas that skipped out of the sand, and his skin had long been toughened to the bloodthirsty night insects of the islands. Yet he had made a decided failure at the attempt to sleep.

Why? It surely couldn't be nervousness over the fact of strange surroundings and loneliness. Alan Carver had spent too many nights in wild and solitary places for that. Yet the night sounds had kept him in a perpetual state of half-wakeful apprehension, and at least a dozen times he had started to full consciousness in a sweat of nervousness. Why?

He knew why. It was the night sounds themselves. Not their loudness nor their menace, but their — well, their variety. He knew what darkness ought to bring forth in the way of noises; he knew every bird call and bat squeak indigenous to these islands. But the noises of night here on Austin Island had refused to conform to his pattern of knowledge. They were strange, unclassified, and far more varied than they should have been; and yet, even through the wildest cry, he fancied a disturbing note of familiarity.
