For four long years, Derwent Conniston has chased outlaw John Keith across the Canadian Arctic. Conniston, a member of the Royal Northwest Mounted Police, falls gravely ill in the course of his dogged pursuit, and to his amazement the accused murderer comes to his rescue. Although they're on opposite sides of the law, the two men find they have a remarkable lot in common, including an uncanny physical resemblance. By the time Conniston realizes that his sickness is fatal, he has come to believe in Keith's professed innocence. The unlikely friends and virtual twins devise a daring plot in which they swap identities in order to give Keith a chance to redeem himself. Upon his return to the scene of the crime in Prince Albert, Saskatchewan, Keith assumes his new role as a Mountie and begins an investigation to clear his name — only to fall into a plot involving blackmail, murder, and forbidden love. James Oliver Curwood's firsthand knowledge of the Canadian Northwest adds a rugged realism to this bestselling novel of action and romance. Readers with a taste for stories in the robust style of Jack London and Zane Grey will savor this frontier adventure.
