Itinerant journalist Ash Upson was a true "rolling stone" of the western frontier, first kicking around New York with Edgar Allen Poe and then tutoring the children of Mormon leader Brigham Young in Utah before making his way to New Mexico. There he befriended two of the Wild West's greatest legends: outlaw Billy the Kid and the man who slayed him, Sheriff Pat Garrett. Told mostly through Upson's own letters to his family back East, learn the history of the Lincoln County War, Billy the Kid, and Pat Garrett firsthand from the very man who knew them best: Ash Upson.
