All Patrick O'Brian's strengths are on parade in this novel of action and intrigue, set partly in Malta, partly in the treacherous, pirate-infested waters of the Red Sea. While Captain Aubrey worries about repairs to his ship, Stephen Maturin assumes the center stage for the dockyards and salons of Malta are alive with Napoleon's agents, and the admiralty's intelligence network is compromised. Maturin's cunning is the sole bulwark against sabotage of Aubrey's daring mission.

Captain Jack Aubrey, R. N., ashore after a successful cruise, is persuaded by a casual acquaintance to make certain investments in the City. This innocent decision ensnares him in the London criminal underground and in government espionage the province of his friend Stephen Maturin. Is Aubrey's humiliation and the threatened ruin of his career a deliberate plot? This dark tale is a fitting backdrop to the brilliant characterization and sparkling dialogue which O'Brian's readers have come to expect."
