Did Pat Garrett kill the wrong man in 1881 in Fort Sumner, New Mexico, or did the outlaw known as Billy the Kid live on as William Henry Roberts until 1948? W. C. Jameson analyzes the evidence, including use of new technology to produce a compelling case for Billy's survival. Heralded by Booklist as an enjoyable reexamination of a legendary piece of Americana, this book traces the life of the famous desperado and the controversy that still is debated today.
