"Huh?" questioned the sleepy man.

"I will stand watch for you," repeated Nu. "I would meet—" and he mumbled a name that might have been anything, "she said that she would come to me tonight during the second watch."

Nu could hear the man chuckle.

"Give me your robe," said Nu, "that all may think that it is you," and he reached his hand for the horn crowned aurochs skin.

Throk passed it over, only too glad to drop back again into the slumber that his fellow had disturbed. Nu drew the bull's head over his own, the muzzle projecting like a visor, and the whole sitting low upon his head threw his features into shadow. Nu stepped out upon the platform. The other sentry was standing impatiently waiting his coming, at sight of him the fellow turned and walked toward one of the dwellings that stretched further into the lake. There were seven in all that were joined to the shore by this single causeway—Nu had entered the one nearest the land.

In which was the prisoner, and was she even in any of this particular collection of dwellings? It was equally possible that she might be in one of the others of which Nu had counted not less than ten stretching along the shore of the lake for at least a mile or more. But he was sure that they had first brought her to one of the dwellings of this unit—he had seen them cross the causeway with her. Whether they had removed her to some other village later, he could not know. If there was only some way to learn definitely. He thought of the accommodating and sleepy Throk—would he dare venture another assault upon the lunk-head's credulity. Nu shrugged. The chances were more than even that he would not find the girl before dawn without help, and that whether he did or no he never would escape from the village with his life. What was life anyway, but a series of chances, great and small. He had taken chances before—well, he would take this one.

He re-entered the dwelling and walked noisily to Throk's side. Stooping he shook the man by the shoulder. Throk opened his eyes.

"In which place is the prisoner?" asked Nu. He had come near to saying cave, but he had heard Gron speak of the hide and thatch things which protected them from the rains by another name than cave, and so he was bright enough to guess that he might betray himself if he used the word here. For the most part his language and the language of the Lake Dwellers was identical, and so he used a word which meant, roughly, in exactly what spot was the captive secured.

"In the last one, of course," grumbled the sleepy Throk.

Nu did not dare question him further. The last one might mean the last of this unit of dwellings or it might mean that she was in the last village, and Nu did not know which the last village might be, whether north or south of the village where he was. Already he could feel the eyes of the man searching through the darkness toward him. Nu rose and turned toward the doorway. Had the fellow's suspicions been aroused—had Nu gone too far?
