Book excerpt: A killer is on the loose in the Arizona Territory. One by one, Tonto Basin ranchers are being murdered for their livestock. And the Cattle Raisers Association has hired two range detectives to catch the culprit. From the looks of them, Stovepipe Stewart and Wilbur Coleman are just another pair of high plains drifters. But with their razor-sharp detective skills and rare talent for trouble, they're the last remaining hope for one young cowboy who's been arrested for the murders.
