Territorial marshals Virgil Cole and Everett Hitch thought things had finally calmed down in Appaloosa when Boston Bill Black's murder charge was dropped. But all that changed when Augustus Nobel Driggs rolled into town. Square-jawed, handsome, and built like a muscled thoroughbred stallion, Driggs intimidates even his guards from inside his prison cell. In a haunting twist of fate, Driggs and a pack of cold-blooded convicts are suddenly on the loose--and it's up to any and all territorial lawmen, including Cole and Hitch, to capture the fugitives and rescue the woman kidnapped during their escape. But nothing is ever quite what it seems with the ever-elusive Driggs. Finally free, he's quickly on his own furious hunt for a hidden cache of gold and the men who double-crossed him. With an unlikely and unconventional Yankee detective by their side, Cole and Hitch set off on a massive manhunt. As horses blaze and guns echo deafening reports, Driggs discovers one of the lawmen on his trail is none other than a fellow West Point graduate and one of the very men who betrayed him and left him for dead. Ruthless and willing to leave a bloody path of destruction in his wake, Driggs seeks vengeance at any cost.
