Phantom of the Plains

Red Ryder and Little Beaver return to Blue Springs and learn that the Duchess, Red's aunt, is going to sell her stagecoach line and marry a snooty Englishman Talbot Champneys, who is really Fancy Charlie, who has the nasty habit of marrying rich women and then killing them for their fortune. The concerned Red thinks everything is okay until he sees Champneys mistreating Red's horse, Thunder, and he then decides to investigate Champneys.
