Marshal, gunfighter, stage driver, and scout, Wild Bill Hickok had a legend as big and untamed as the West itself. No man was as good with a gun as Wild Bill, and few men used one as often. From Abilene to Deadwood, his name was known by all—and feared by many. That's why he was hired by Allan Pinkerton's new detective agency to protect an eccentric inventor on a train ride through the worst badlands of the West. With hired thugs out to kill him and angry Sioux out for his scalp, Bill knew he had his work cut out for him. But even if he survived that, he had a still worse danger to face—a jealous Calamity Jane.
