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 because, as he tells Little Beaver, no true Englishman would mistreat a horse. Realizing that he doesn’t have much time with Red snooping around, the western Bluebeard persuades the Duchess to return to England with him, meet him at the railroad station to be married and, oh yes, bring her money with her.
