So Lafond, after his first impulse to get away from the scene of his deed had spent itself, jogged along unmolested toward Rapid. His brain was working like lightning, but always on one line. He saw himself alone, standing opposed to this huge black Bad-luck. Everything was against him. But they couldn't get him down. He was Man-who-speaks-Medicine, the Sioux; he was Lafond, the half-breed; he was Black Mike, the pioneer. Let them come on! They thought they could corner him. He would show them. One was gone. There remained the other two. Lafond's mind saw red; he was set on murder. No consideration of reason, probability, or common sense obtruded itself athwart his plan. He could perceive one fact--that three men knew his secret, of whom one was dead and the other two were living. Why Knapp and Buckley should have told Durand; what they expected to gain by going to Rapid; or what benefit the naturalist imagined could accrue to him from his insinuating the state of affairs to the half-breed, the latter did not inquire. He only knew that he wanted to catch Knapp's buckboard before it had left the pine belt. Ambush would then be easier. He lashed his horses unmercifully. Rockerville told him the two men had passed through not half an hour before, and wondered at the wildness of his eye. That was well. They could not escape him now, for their wagon was heavily loaded, and they were travelling leisurely, having no reason for haste. Remembering appearances, he told Rockerville that it did not much matter, he would not try to catch up; and then drove back toward Copper Creek, only to make a detour by a wood road into the Rapid trail again. As he approached the foothills, he could hear occasionally the creak of a brake below him, by which he knew that he was drawing near. He slowed up at once, for he knew of a short cut a mile or so ahead, which the prospectors would not attempt because of their heavy load, but by which he could come out ahead of his victims. Then he would lie in wait. The short cut in question dipped steeply down into the bed of a creek, and as steeply up on the other side; while the main stage-road made a long horseshoe curve around the head of the cañon. Lafond decided to drive rapidly down, to leave his team in the creek bottom, and to climb on foot to the level of the main road on the other side. In the meantime he drew as near to the other wagon as he could without being seen. The minutes seemed to drag.
