Soft-spoken, cheerful, handsome, and well dressed, George West Musgrave ""looked more like a senator than a cattle rustler."" Yet he was a cattle rustler as well as a bandit, robber, and killer, ""guilty of more crimes than Billy the Kid was ever accused of."" In Last of the Old-Time Outlaws, Karen Holliday Tanner and John D. Tanner, Jr., recount the colorful life of Musgrave (1877-1947), enduring badman of the American Southwest.

Musgrave was a charter member of the High Five/Black Jack gang, which was responsible for Arizona's first bank hold-up, numerous post office and stagecoach robberies, and the largest Santa Fe Railroad heist in history. Following a decade-long hunt, he was captured and acquitted of killing a former Texas Ranger. After this near brush with prison or execution, he headed for South America, where he gained fame as the leading Gringo rustler. It wasn't until the 1940s that Musgrave's age and poor health brought an end to a criminal career that had spanned two continents and two centuries.

Incorporating previously unknown facts about the career of this frontier outlaw, the Tanners thoroughly document Musgrave's half-century of crime, from his childhood in the Texas brush country to his final days in Paraguay.
