Bill's recent experiences had caused him to regard the agent with new hatred, not unmixed with fear. The obvious thing for Lowell to have done was to have rushed more men on the trail and captured Talpers and McFann before they crossed the reservation line. It could have been done, with Fire Bear doing the trailing. Even the half-breed admitted that much. But, instead of carrying out such a programme, the agent had sent Fire Bear and Plenty Buffalo with word that the trader might come back--that no prosecution was intended. Clearly enough such an unusual proceeding indicated that the girl was still afraid on account of the letter, and had persuaded the agent to abandon the chase. There was the key to the whole situation--the letter! Bill determined to guard it more closely than ever. He opened his safe frequently to see that it was there. As a whole, then, things were not breaking so badly, Bill figured. To be sure, it would have cleared things permanently if Jim McFann had done as he had been told, instead of weakening in such unexpected and absurd fashion. Bringing that girl into camp, as Jim had done, had given Talpers the most unpleasant surprise of his life. He had come out of the affair luckily. The letter was what had done it all. He would lie low and keep an eye on affairs from now on. McFann would have no difficulty in shifting for himself out in the sagebrush, now that he was alone. Bill would see that he got grub and even a little whiskey occasionally, but there would be no more assignments for him in which women were concerned, for the half-breed had too tender a heart for his own good! The Indian agent stopped at Bill's store occasionally, on his way to and from the Greek Letter Ranch. Their conversation ran mostly to trade and minor affairs of life in general. Even the weather was fallen back upon in case some one happened to be within earshot, which was usually the case, as Bill's store was seldom empty. No one who heard them would suspect that the men were watching, weighing, and fathoming each other with all the nicety at individual command. Talpers was always wondering just how much the Indian agent knew, and Lowell was saying to himself: "This scoundrel has some knowledge in his possession which vitally affects the young woman I love. Also he is concerned, perhaps deeply, in the murder on the Dollar Sign road. Yet he has fortified himself so well in his villainy that he feels secure." For all his increased feeling of security, Talpers was wise enough to let the bottle alone and also to do no boasting. Likewise he stuck faithfully to his store--so faithfully that it became a matter of public comment.
