On July 14, 1882, the notorious Texas gunman, John Peters Ringo, was found beneath a blackjack oak tree some distance from Tombstone, Arizona, with a bullet in his head. Colonel Henry Hooker, Billy Breakenridge, Wyatt Earp, and Doc Holliday were all suspected of doing him in, but charges were never brought against anyone. Was this going to be an unsolved mystery? The answer could lie in this blending of fact with fiction woven into the lives of these famous characters of the Old West, and those of the less-well-known Frank Buckskin Leslie, bartender, part-time army scout, and awesome gunfighter; the woman he wanted -- the beautiful and fiercely independent Nell Cashman; and Louis Hancock, a big, black rancher determined to avenge a heinous crime.
