In celebration of the bicentennial of the Texas Rangers in 2023, Tom Clavin tells the riveting story of Leander McNelly, the revered and fearless Texas Ranger captain in the 1870s. Although his tenure was short, McNelly made a lasting impression on the frontier justice system and his Rangers became the precursor to the modern federal law enforcement agencies of today. Under McNelly’s leadership, the Rangers waged many dramatic campaigns resulting in cattle thieves, desperadoes, border ruffians and other dangerous criminals going to jail or worse. It is a story of a man who dedicated himself to bringing justice to a wild and thriving western frontier.
