prisoner, and lest he should escape by night when Barney slept Greystoke set Terkoz to watch over him. But Nu did not seem inclined to wish to escape. His one desire apparently was to master the strange tongue of his captors. For two weeks after he was able to quit his bed he devoted his time to learning English. He had the freedom of the ranch, coming and going as he pleased, but his weapons were kept from him, hidden in Lord Greystoke's study, and Barney, sometimes with others of the household, always accompanied him. Nu was waiting for Nat-ul. He was sure that she would come back again to this cave that his new acquaintances called a bungalow. Barney was waiting for the man to mention his sister. One day Curtiss came upon Nu sitting upon the veranda. Terkoz lay at his feet. Nu was clothed in khaki—an old suit of Greystoke's being the largest that could be found upon the place, and that was none too large. As Curtiss approached, the wolfhound turned his wicked little eyes upon him, without moving his head from where it lay stretched upon his forepaws, and growled. Nu extended a booted foot across the beast's neck to hold him in check. The hound's show of hostility angered Curtiss. He hated the brute, and he hated Nu as cordially—just why, he did not know, for it seemed that his hatred of the stranger was a thing apart from his righteous anger in his belief that the man had guilty knowledge of the fate of Victoria Custer. He halted in front of the caveman. "I want to ask you a question," he said coldly. "I have been wanting to do so for a long time; but there has always been someone else around." Nu nodded. "What can Nu tell you?" he asked. "You can tell me where Miss Custer is," replied Curtiss. "Miss Custer? I do not know what you mean. I never heard of Miss Custer." "You lie!" cried Curtiss, losing control of himself. "Her jacket was found beneath your head in that foul den of yours." Nu came slowly to his feet. "What does 'lie' mean?" he asked. "I do not understand all that people say to me, yet; but I can translate much from the manner and tone of the saying, and I do not like your tone, Curtiss." "Answer my question," cried Curtiss. "Where is Victoria Custer? And when you speak to me remember that I'm Mr. Curtiss—you damned white nigger." "What does 'lie' mean?"
