 When Bertie is instructed by Aunt Agatha to break up his uncle s engagement to a young waitress, he arranges a luncheon for his uncle and the girl s aunt, a common, gaudy woman -- who turns out to be the uncle s long-lost barmaid love. To escape Aunt Agatha s wrath, Bertie and Jeeves travel to the country residence of a friend to enjoy the local fair, where the bookie manages to handicap all the entrants on which Bertie and his friends bet.
