Six-gun melody / William Colt MacDonald.

Melody Madigan is a cowpuncher who ordinarily leaves trouble alone. But when it comes in the form of a man with a gun in his hand, looking for him, he's the last man to back away from it - which is usually bad news as far as the troublemaker is concerned. For instance, there's Bull Badgely, one of the surliest gunmen who ever shot an unarmed man. And there's the tough gang led by the Du Sang brothers - slick, conniving rustlers who are trying to starve out their rivals, the Norrises, and run off their cattle. So when Melody meets the lovely Jerry Norris and learns of her family's plight, he reckons he's found a cause to get behind.
