"I went into lots of fights by myself, and I came out by myself, too!" said Captain Manuel T. "Lone Wolf" Gonzaullas of the Texas Rangers. In this lively biography, Brownson Malsch describes Gonzaullas's career, first as a major in the Mexican Army and then as an agent of the U.S. Treasury Department, before he joined the Rangers in 1920.

Although trained as an "old-style" Texas Ranger, Gonzaullas was an early advocate of scientific crime-detection methods and was instrumental in setting up the state's first modern crime-detection facility. His many cases included the Santa Claus bank robbery in Cisco, the famous courtroom burning and lynching in Sherman, the race riots in Beaumont, and the Phantom Killer episode near Texarkana. Following his retirement in 1951, Gonzaullas developed a career as a Hollywood technical adviser.

Illustrated with many photographs of Gonzaullas, his associates, and his weaponry, this edition also includes a new introduction by Texas Ranger historian Harold J. Weiss, Jr.
