First he became a killer. Then he became a legend. John Wesley Hardin was fifteen when he killed his first man. Before his murderous ways ended, he'd killed forty-two men in cold blood -- one, the legend goes, for snoring. From then on, Hardin stayed true to his calling, living a fever dream of lightning fast draws and flying lead. By seventeen, Hardin had a deadly reputation for killing that drew traitors, backstabbers, and wannabe gunslingers -- all for a chance to gun down the man who had turned killing into an all-American legend.
