Thurston of Orchard Valley by Harold Bindloss

These were weighty reasons why Christy Black, whose comrades reversed his name and called him Black Christy instead, remained in Thurston's camp as long as he did. Although a good mechanic, he was by no means fond of manual labor, and he had discovered that profitable occupations were open to an enterprising and not over-scrupulous man. On the memorable night when Thurston fished him out of the river, his rescuer had made it plain that he must earn the liberal wages that were promised to him. As a matter of fact, Black had made the most of his opportunities, and in doing so had brought himself under the ban of the law during an altercation over a disputed mineral claim.

Black, who then called himself by another name, disappeared before an inquiry as to how the body of one of the owners of the claim came into a neighboring river. Only one comrade, and a mine-floating speculator, who stood behind the humbler disputants, knew or guessed at the events which led up the fatality. The comrade shortly afterwards vanished, too, but the richer man, who had connived at Black's disappearance, kept a close hand on him, forcing him as the price of freedom to act as cat's-paw in risky operations, until Black, tired of tyranny, had been glad to tell Thurston part of the truth and to accept his protection. The man from whose grip he hoped he had escaped was the one who had helped Leslie out of a difficulty.
