No Texas Ranger memoir has captured the public's imagination like Joaquin Jackson's One Ranger. Readers thrilled to Jackson's stories of catching criminals and keeping the peace across a wide swath of the Texas-Mexico border—and clamored for more. Now in One Ranger Returns, Jackson reopens his case files to tell more unforgettable stories, while also giving readers a deeply personal view of what being a Texas Ranger has meant to him and his family.

Jackson recalls his five-year pursuit of two of America's most notorious serial killers, Henry Lee Lucas and Ottis Toole. He sets the record straight about the role of the Texas Rangers during the United Farm Workers strike in the Rio Grande Valley in 1966-1967. Jackson also describes the frustration of trying to solve a cold case from 1938—the brutal murder of a mother and daughter in the lonely desert east of Van Horn. He presents a rogue's gallery of cattle rustlers, drug smugglers, and a teetotaling bootlegger named Tom Bybee, a modest, likeable man who became an ax murderer. And in an eloquent concluding chapter, Jackson pays tribute to the Rangers who have gone before him, as well as those who keep the peace today.
