Stranded after the loss of Diane, Aubrey and Maturin build a small vessel and survive an attack before reaching British-held Batavia. Stamford Raffles supplies Jack with a captured ship, renamed Nutmeg of Consolation, for the voyage toward Australia.
Pursuit by a French frigate gives way to the penal colony of New South Wales, where Stephen investigates abuses of authority and Jack confronts colonial politics. The novel links East Indies warfare with transportation, punishment and the growing British presence in Australia.
