The River's End by James Oliver Curwood — Read

Keith lost no time in heading for Shan Tung's. He was like a man playing chess, and the moves were becoming so swift and so intricate that his mind had no rest. Each hour brought forth its fresh necessities and its new alternatives. It was McDowell who had given him his last cue, perhaps the surest and safest method of all for winning his game. The iron man, that disciple of the Law who was merciless in his demand of an eye for an eye and a tooth for a tooth, had let him understand that the world would be better off without Shan Tung. This man, who never in his life had found an excuse for the killer, now maneuvered subtly the suggestion for a killing.

Keith was both shocked and amazed. "If anything happens, let it be in the open and not on Shan Tung's premises," he had warned him. That implied in McDowell's mind a cool and calculating premeditation, the assumption that if Shan Tung was killed it would be in self-defense. And Keith's blood leaped to the thrill of it. He had not only found the depths of McDowell's personal interest in Miriam Kirkstone, but a last weapon had been placed in his hands, a weapon which he could use this day if it became necessary. Cornered, with no other hope of saving himself, he could as a last resort kill Shan Tung -- and McDowell would stand behind him!
