The dead ringer

"Clint Adams is playing high-stakes poker when his game is interruptedby a mysterious Mexican woman - who shoots first and asks questions later. After the beauty sinks a slug into the Gunsmith's shoulder, she tells him she's there to settle a score. Her brother is in jail, falsely accused of murder. The real killer, her brother says, is a man named Clint Adams. Someone's been impersonating the Gunsmith, and now an innocent man's life hangs in the balance. Whoever this pistol-packing pretender is, he's about to find out the hard way - the West ain't big enough for two Gunsmiths"-- Cover verso.
