This new, in-depth life of Henry McCarty, alias Billy Bonney, alias Billy the Kid, offers fresh perspectives, not only on the Lincoln County War and his boyhood in Silver City, New Mexico, but also on his Irish mother's origins and immigration to Indiana, his public-school education in Indianapolis, the McCarty family moves to Wichita, Kansas, and Santa Fe, and his two-year outlaw adventures in Arizona. This work gives us, for the first time, the whole person. It brings together a huge amount of material, much of it made available to researchers only in recent years. The result is an original, authoritative, and provocative portrait of Billy the Kid as both outlaw and frontier fighter against the infamously corrupt Santa Fe Ring.
