is a daughter. As the high level traitor in British intelligence is not yet identified, the time on land raises risks to his friend Jack Aubrey, who agrees to sail immediately. Aubrey, Maturin, and their shipmates prepare for a mission to sail the letter of marque Surprise on a mission to South America. Upon reaching Lisbon, Sir Joseph Blaine intercepts Maturin with news that he and Aubrey are required to carry a diplomat to the Sultan of Pulo Prabang, a piratical Malay state in the South China Sea. Edward Fox is the envoy leading the mission to persuade the Sultan to become an English rather than French ally. The French mission includes the same English traitors - Ledward and Wray - who were responsible for Aubrey's former disgrace. With the Surprise under the command of Captain Pullings, Aubrey and Maturin return with Blaine to England, where Lord Melville, First Lord of the Admiralty, reinstates Aubrey as a Post-Captain in the Royal Navy and gives him command of the recently captured French ship Diane. The voyage south forms the crew, with frequent training on the guns; by the luck of a timely breeze and much hard rowing in the ship's boats, Diane escapes the inshore currents of Inaccessible Island. Sailing through the high forties (south latitude), she first touches land at Java, meeting Lieutenant Governor Raffles near Batavia, where they hear the first word of bank failures in England. Arriving in Pulo Prabang, Maturin meets fellow natural philosopher van Buren and helps the arrogant envoy Fox plot against the French mission.

Returning to town, he learns that Abdul, the Sultan's cupbearer and catamite has been caught in a compromising position with both Ledward and Wray. Abdul is executed and Ledward and Wray are banished from the court for their indiscretions, effectively ending the French mission. Wray and Ledward are eventually assassinated and Maturin and van Buren dissect their bodies. After a feast to celebrate the treaty, at which Fox and his retinue behave without discretion, the Diane makes for Batavia and to rendezvous with the Surprise. Fox behaves with increasing arrogance during the return voyage, the success of the treaty having gone to his head. After missing
