Horatia calls upon her brother Pelham and his friend, Mr Pommeroy, to restore the brooch to her before Rule returns from his estate. They are unsuccessful because Rule's jealous cousin, Mr Drelincourt, has found the brooch at Lethbridge's house and has immediately set forth for Rule's country estate to share this news. Lethbridge overtakes Drelincourt on the road and wrests the brooch from him. Drelincourt continues on his journey anyway and Rule is furious at his cousin's insinuation that Horatia and Lethbridge are having an affair. Rule sets off back to London, meets Lethbridge on the way and the two men have a swordfight, which Rule wins. Meanwhile, Pelham and his posse plan to hold up Lethbridge's carriage and steal back the brooch. However, they get the carriages confused and accidentally hold up Rule's carriage instead (Lethbridge still being in the country, recovering from his wounds).
