The Wild Gun — Jory Sherman

When ranchers have a problem with horse thieves or claim jumpers, they send for the Wild Gun--Cordwainer "Cord" Wild. A loner seldom seen in town, Cord always tries to apprehend his charges peaceably, but more often than not he is forced to bring them in boots first...

When Cord tracks down a pair of horse thieves and kills them in self-defense, he finds himself facing down a powerful enemy from his past. The two men worked for Horace Weatherall, an outlaw closely tied to the murder of Cord's father. And after seeing the bodies of his men, Horace is determined to see Cord go the same way.
