Fred tells Glossop the Duke is on the train and Glossop can save time by talking with him, and then heading back to London. Fred is not aware that the stranger is Rupert Baxter, now working for the Duke. Arriving at Blandings, they are met by Lord Bosham, who was conned out of his wallet by Uncle Fred the previous day. Baxter is sacked by the Duke because he was seen at a ball in London by Horace, but is taken on again when Fred, as Glossop, persuades Horace and the Duke that Horace is suffering delusions. Horace heads off for a rest-cure, and Baxter is left unable to reveal that he has seen through Fred's disguise, having met the real Glossop before. Baxter is put on his guard, and informs Constance; she in turn wants to hire a detective to deal with these imposters. Bosham remembers Mustard Pott, and calls him to Blandings. Dunstable's scheme to acquire the pig continues apace, and he calls in his strapping nephew to help, but when Gilpin asks for funds to buy an onion soup bar, thus enabling him to marry Polly, the two row and part. Dunstable ropes in Baxter instead. Uncle Fred, meeting Pott just after he has won £250 from Bosham at "Persian Monarchs", takes the money off him, insisting it will help Polly marry wealthy Horace. Pott, meeting Gilpin at The Emsworth Arms, tells him about Polly being engaged to Horace, and the enraged Gilpin chases a fearful Horace back to the Castle. Fred gives the money to Pongo to pass on to Polly for Gilpin's benefit, but Gilpin spurns her and Pongo uses the returned cash to pay off his debts. When Fred reconciles Gilpin and Pongo, another £250 is required. Pott is persuaded to take it from Dunstable at "Persian Monarchs", but the wily peer wins himself £300. Both Fred and Pott try to get it back, but Dunstable has the pig, captured earlier by Baxter, hidden in his bathroom, and is keeping his room under lock and key. Having knocked out the vigilant Baxter with a Mickey Finn, Fred finally gains access to the room shortly after Pott has done the same, Pongo having lured Dunstable away with a rendition of "The Bonnie Banks". Fred is caught by a shotgun-bearing Bosham, just as Pott, having discovered the Empress in the bathroom, drinks a second Mickey destined
