Award-winning author Bob Alexander presents a biography of 20th-century Ranger Captain Jack Dean, who holds the distinction of being one of only five men to serve in both the Officer’s Corps of the Rangers and also as a President-appointed United States Marshal.

Jack Dean’s service in Texas Ranger history occurred at a time when the institution was undergoing a philosophical revamping and restructuring, all hastened by America’s Civil Rights Movement, landmark decisions handed down by the United States Supreme Court, zooming advances in forensic technology, and focused efforts designed to diversify and professionalize the Rangers. His job choice caused him to circulate in the duplicitous underworld of dishonesty and criminality where twisted self-interest overrode compliance with societal norms. His biography is packed with true-crime calamities: double murders, single murders, negligent homicides, suicides, jailbreaks, manhunts, armed robberies and home invasions, kidnappings, public corruption, sexual assaults, illicit gambling, car-theft rings, dope smuggling, and arms trafficking.
