The returns from his interest in the gang's rustling operations had been far more than Bill had ever secured from his store. In fact, storekeeping was played out. Bill never would have kept it up except for the opportunity it gave him to find out what was going on. To be sure, he should have played safe and kept away from such things as that affair on the Dollar Sign road. But he could have come clear even there if it had not been for the uncanny knowledge possessed by that girl. The thought of what would happen if she took a notion to tell McFann how he had been "double-crossed" by his partner gave Talpers something approaching a chill. The half-breed was docile enough as long as he thought he was being fairly dealt with. But once let him find out that he had been unfairly treated, all the Indian in him would come to the surface with a rush! Fortunately the girl was proving herself to be close-mouthed. She had traveled for hours with the half-breed without telling him of Talpers's perfidy. Now Bill would see to it that she got no chance to talk with McFann. The half-breed was too tender-hearted where women were concerned. That much had been proved when he had fallen down in the matter of the work he had been sent out to do. If she had a chance the girl might even persuade him to let her escape, which was not going to do at all. If anybody was to be left holding the sack at the end of the adventure, it would not be Bill Talpers! With various stratagems being brought to mind, only to be rejected one after another, Talpers watched the tent until midnight, the half-breed sleeping near at hand. Then Bill turned in while McFann kept watch. As for Helen, she slept the sleep of exhaustion until wakened by the touch of daylight on the canvas. With senses preternaturally sharpened, as they generally are during one's first hours in the wilderness, Helen listened. She heard Talpers stirring about among the horses. It was evident that he was alarmed about something, as he was pulling the picket-pins and bringing the animals closer to the center of the glade. McFann had been looking down the valley from the sentinel rock. She did not hear him come into camp, as the half-breed always moved silently through underbrush that would betray the presence of any one less skilled in woodcraft. She heard his monosyllabic answers to Talpers's questions. Then Bill himself pushed his way through the underbrush and climbed the rock. When he returned to the camp he came to the tent. "I don't mind tellin' you that Plenty Buffalo is out there on the trail, with an Injun policeman or two. That young agent don't seem to have had nerve enough to come along," said Talpers, producing a small rope. "I'll have to tie your hands awhile, just to make sure you don't try gittin' away. I'm goin' to tell 'em that at the first sign of rushin' the camp you're goin' to be shot. What's more I'm goin' to mean what I tell 'em."
