No man could handle a gun as well as Wild Bill Hickok, and few men used one as often. That"s why he"s 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 knows he has his work cut out for him. But even if he survives that, he still has a worse danger to face--a jealous Calamity Jane.
