In 1892, or thereabouts, John Wesley Hardin drifted into Greentree, Wyoming, and rented an upstairs room in a hotel. During the night men broke in with blazing guns. One of the bullets glanced off his head and he fell through the window to the alley below. Before his assailants could reach him to make sure he was dead, a pretty girl (who was also being hunted by thugs in this town) came along and rescued him. He could not remember his name or where he was from. In time he learned that he was fast with a gun and knew more about horses than he did about cattle. But from the clothes he was wearing he might have been a gambler or perhaps a bounty hunter. In one of his pockets was a wanted poster of Bill Longley, a gunslinger from Texas, and a letter addressed to a "J. W. Hard--". The last part of the name was obscured. The girl, heir to a large cattle ranch in the Wind River Range, took a shine to this man, whom she called 'Slim', and because of her he ended up in a range war and deeply in love. Nothing since Louie L'Amour comes close to this rollicking comedy/romance/tragedy in terms of pure dee ole Western savvy and realism.
