Billy the Kid--a.k.a. Henry McCarty, Henry Antrim, and William Bonney--was a horse thief, cattle rustler, charismatic rogue, and cold-blooded killer. A superb shot, the Kid gunned down four men single-handedly and five others with the help of cronies. Two of his victims were Lincoln County, New Mexico, deputies killed during the Kid's brazen daylight escape from the courthouse jail on April 28, 1881.

For new sheriff Pat Garrett, an acquaintance of Billy's, the chase was on. . . .

The first dual biography of the Kid and Garrett, To Hell on a Fast Horse re-creates the thrilling manhunt for the Wild West's most iconic outlaw. Mark Lee Gardner digs beneath the myth to take a fresh look at these two men, their relationship, and their epic ride to immortality.
