When the tracks of the Santa Fe Railroad reached southern Colorado, Modoc City, like many another sleepy little hamlet, overnight became a boom town. But along with progress came hard-faced ex-convicts determined to wrest quick fortunes from the strongboxes carried in the trains that were beginning to travel over the newly laid tracks.

       The first inkling of one of the most daring of all such attempts came from a frightened little Mexican tramp who, hiding in a boxcar in the Santa Fe yard one night, overheard two men plotting. Sheriff Holland paid with his life because he did not believe what little Pedro repeated. Three desperate criminals made an amazing jailbreak because Judge Pickett did not understand what Pedro told him––but the Lone Ranger and Tonto both believed and understood.

       How the masked man and his faithful Indian friend risked death over and over in their attempt to foil a three-hundred-thousand-dollar train robbery and bring Slim Norton and his band of thugs to justice makes one of the most exciting railroad adventure yarns you'll read in a long time.
