Gunman's Reckoning by Max Brand

But Donnegan had leaped clear of the roadbed, and he struck almost to the knees in a drift of sand. Otherwise, he might well have broken his legs with that foolhardy chance. As it was, the fall whirled him over and over, and by the time he had picked himself up the lighted caboose of the train was rocking past him. Donnegan watched it grow small in the distance, and then, when it was only a red, uncertain star far down the track, he turned to the vast country around him.

The mountains were to his right, not far away, but caught up behind the shadows so that it seemed a great distance. Like all huge, half-seen things they seemed in motion toward him. For the rest, he was in bare, rolling country. The sky line everywhere was clean; there was hardly a sign of a tree. He knew, by a little reflection, that this must be cattle country, for the brakie had intimated as much in their talk just before dusk. Now it was early night, and a wind began to rise, blowing down the valley with a keen motion and a rapidly lessening temperature, so that Donnegan saw he must get to a shelter. He could, if necessary, endure any privation, but his tastes were for luxurious comfort. Accordingly he considered the landscape with gloomy disapproval. He was almost inclined to regret his plunge from the lumbering freight train. Two things had governed him in making that move. First, when he discovered that the long trail he followed was definitely fruitless, he was filled with a great desire to cut himself away from his past and make a new start. Secondly, when he learned that Rusty Dick had been killed by Joe, he wanted desperately to get the throttle of the latter under his thumb. If ever a man risked his life to avoid a sin, it was Donnegan jumping from the train to keep from murder.
