Wyatt Earp had managed to stay alive in Wichita, Dodge City and Tombstone because he was more intelligent than the gunslingers, outlaws and hoodlums who hated him. But Old Man Clanton, who controlled Cochise County, Arizona, had never really worked at the job of killing him. To slay a John Law, even in Arizona Territory, was a last resort which sensible hoodlums shrank from. Marshal Earp, however, had become an intolerable menace to the Clantons and the Ten Percent Ring in Tucson. The time had come to kill Wyatt Earp and Clanton had no intention of failing.
