While in the Mexican badlands, Arizona Ranger Sam Burrack teams up with a young Secret Service agent to stop Desmond Prew and his band of American mercenaries from stealing weapons from U.S. Army supply trains. Original.
Very descriptive. The first western novel I've read. Ralph Cotton is obviously very good at it. Guns, outlaws, attractive women all the good stuff. It did still however seem a little shy in story depth. Still would recommend.
