A train is robbed by masked robbers on its way to the gold-mining region of the Rocky Mountains and a man is murdered ruthlessly in the process. Our hero who is the sole witness of the crime suffers a terrible brain fever and loses his memory including, the name of the murderer. But as fate would have it, the murderer is the leader of the gang but pretends to be a law-abiding citizen of the same town where our hero now lives with a new name and new identity. Will the murder be ever discovered? And will the justice be served in this hostile region?Upon a small station on one of the transcontinental lines winding among the mountains far above the level of the sea, the burning rays of the noonday sun fell so fiercely that the few buildings seemed ready to ignite from the intense heat. A season of unusual drought had added to the natural desolation of the scene. Mountains and foot-hills were blackened by smouldering fires among the timber, while a dense pall of smoke entirely hid the distant ranges from view. Patches of sage-brush and bunch grass, burned sere and brown, alternated with barren stretches of sand from which piles of rubble rose here and there, telling of worked-out and abandoned mines. Occasionally a current of air stole noiselessly down from the canyon above, but its breath scorched the withered vegetation like the blast from a furnace. Not a sound broke the stillness; life itself seemed temporarily suspended, while the very air pulsated and vibrated with the heat, rising in thin, quivering columns.Suddenly the silence was broken by the rapid approach of the stage from a distant mining camp, rattling noisily down the street, followed by a slight stir within the apparently deserted station. Whirling at breakneck pace around a sharp turn, it stopped precipitately, amid a blinding cloud of dust, to deposit its passengers at the depot.One of these, a young man of about five-and-twenty, arose with some difficulty from the cramped position which for seven weary hours he had been forced to maintain, and, with sundry stretchings and shakings of his superb form, seemed at last to pull himself together. Having secured his belongings from out the pile of miscellaneous luggage thrown from the stage upon the platform, he advanced towards the slouching figure of a man just emerging from the baggage-room, his hands thrust deep in his trousers pockets, his mouth stretched in a prodigious yawn, the arrival of the stage having evidently awakened him from his siesta."How's the west-bound-on time?" queried the young man rather shortly, but despite the curtness of his accents there was a musical quality in the ringing tones.Before the cavernous jaws could close sufficiently for reply, two distant whistles sounded almost simultaneously."That's her," drawled the man, with a backward jerk of his thumb over his shoulder in the direction of the sound; "she's at Blind Man's Pass; be here in about fifteen minutes."The young man turned and sauntered to the rear end of the platform, where he paused for a few moments; then, unconscious of the scrutiny of his fellow-passengers, he began silently pacing up and down, being in no mood for conversation with any one. Every bone in his body ached and his head throbbed with a dull pain, but these physical discomforts, which he attributed to his long and wearisome stage ride, caused him less annoyance than did the fact that he had lost several days' time, besides subjecting himself to numerous inconveniences and hardships, on what he now denominated a "fool's errand."
