"Harry Riley and his pal, Dough McLaren, are the type of cowboy that the Old West has always been proud of. Allan Vaughan Elston spins a fine tale of their fighting efforts for the cause of law and order. There's plenty of action as Riley and McLaren start off to capture a gang of train robbers. They fail to recover the stolen loot, but chance to run across an important clue to the mystery of who is blackmailing Jim Hutton. One of Sheridan, Wyoming's leading citizens, Cal Clanton, becomes suspiciously involved, but the evidence is quickly camouflaged by lots of false leads. Hutton, on the brink of losing his ranch, can't help the two cowboys, and they turn to a bright young lawyer, who sees an answer. The thundering climax is filled with gunsmoke as the Clanton gang rides on the Hutton ranch for a showdown. Allan Vaughan Elston's readers have come to appreciate the authenticity with which his books are written. His name has become synonymous with first rate Western fiction."--Back cover.
