"If they get me, it'll be all off with her," he worried, as he followed the two up the canyon. "Swan would have been a help. But he thinks more of catching Al than he does of helping Raine." He looked up and saw that already Swan was halfway up the canyon's steep side, making his way through the brush with more speed than Lone could have shown on foot in the open, unless he ran. The sight heartened Lone a little. Swan might have some plan of his own,--an ambush, possibly. If he would only keep along within rifle shot and remain hidden, he would show real brains, Lone thought. But Swan, when Lone looked up again, was climbing straight away from the little searching party; and even though he seemed tireless on foot, he could not perform miracles. Swan, however, was not troubling himself over what Lone would think, or even what Warfield was thinking. Contrary to Lone's idea of him, Swan was tired, and he was thinking a great deal about Lorraine, and very little about Al Woodruff, except as Al was concerned with Lorraine's welfare. Swan had made a mistake, and he was humiliated over his blunder. Al had kept himself so successfully in the background while Lone's peculiar actions had held his attention, that Swan had never considered Al Woodruff as the killer. Now he blamed himself for Frank's death. He had been watching Lone, had been baffled by Lone's consistent kindness toward the Quirt, by the force of his personality which held none of the elements of cold-blooded murder. He had believed that he had the Sawtooth killer under observation, and he had been watching and waiting for evidence that would impress a grand jury. And all the while he had let Al Woodruff ride free and unsuspected. The one stupid thing, in Swan's opinion, which he had not done was to let Lone go on holding his tongue. He had forced the issue that morning. He had wanted to make Lone talk, had hoped for a weakening and a confession. Instead he had learned a good deal which he should have known before. As he forged up the slope across the ridged lip of the canyon, his one immediate object was speed. Up the canyon and over the divide on the west shoulder of Bear Top was a trail to the open country beyond. It was perfectly passable, as Swan knew; he had packed in by that trail when he located his homestead on Bear Top. That is why he had his cabin up and was living in it before the Sawtooth discovered his presence. Al, he believed, was making for Bear Top Pass. Once down the other side he would find friends to lend him fresh horses. Swan had learned something of these friends of the Sawtooth, and he could guess pretty accurately how far some of them would go in their service. Fresh horses for Al, food--perhaps even a cabin where he could hide Lorraine away--were to be expected from any one of them, once Al was over the divide.
