All Western Winners #2

Young gunman Matthew Masters, the Cactus Kid, wiped out the Davis Gang in a small town in Texas. As a reward, the governor of Texas pardoned him of his previous crimes and helped him become a doctor, abandoning his life as a gunfighter. Years later, now a doctor, Matthew settles in Leadville, Texas. When outlaw Blast Burrows terrorizes local rancher Jim Lathrop and his daughter Marie, Matthew does nothing to help, earning Marie's scorn. Later, when he learns the Lathrops are to be wiped out by Burrows, he disguises himself as the Black Rider, and eliminates the gang, saving Marie from Burrows.
