This tale begins with Jack Aubrey arriving home from his exploits in the Mediterranean to find England at peace following the Treaty of Amiens. He and his friend Stephen Maturin, surgeon and secret agent, begin to live the lives of country gentlemen, hunting, entertaining, and enjoying amorous adventures. Their comfortable existence, however, is cut short when Jack is overnight reduced to a pauper with enough debts to keep him in prison for life.

H.M.S. Surprise follows the variable fortunes of Captain Jack Aubrey's career in Nelson's navy as he attempts to hold his ground against admirals, colleagues, and the enemy, accepting a commission to convey a British ambassador to the East Indies. The voyage takes him and his friend Stephen Maturin to the strange sights and smells of the Indian subcontinent, and through the archipelago of spice island where the French have a near-overwhelming local superiority.

Captain Jack Aubrey, RN, arrives in the Dutch East Indies to find himself appointed to the command of the fastest and best armed frigate in the Navy. He and his friend Stephen Maturin take passage for England in a despatch vessel. But the war of 1812 breaks out while they are en route. Bloody actions precipitate them both into new and unexpected scenes where Stephen's past activities as a secret agent return on him with a vengeance.

On half-pay and without a command, Captain Jack Aubrey is stranded at home in an over-crowded cottage with his large and frequently bad-tempered family. When Jack has almost given up hope of ever returning to sea, Stephen Maturin, ship's doctor, occasional intelligence agent, and Jack's closest friend, brings secret orders that Jack is to take a frigate to the Cape of Good Hope under a Commodore's pennant.

Commissioned to rescue Governor Bligh of Bounty fame, Captain Jack Aubrey and his friend and surgeon, Stephen Maturin, sail the Leopard to Australia with a hold full of convicts. Among them is a beautiful and dangerous spy...and a treacherous disease which decimates the crew.

Jack Aubrey and Stephen Maturin are ordered home by despatch vessel to bring the news of their latest victory to the government. But Maturin is a marked man for the havoc he has wrought in the French intelligence network in the New World, and the attentions of two privateers soon become menacing.

What was daily life in Nelson's navy really like, for everyone from the captain down to the rawest recruit? What did they eat? What songs did they sing? What was the schedule of watches? How were the officers and crew paid, and what was the division of prize-money? These questions and many more are answered in Patrick O'Brian's elegant narrative, which includes wonderful anecdotal material on the battles and commanders that established Britain's naval supremacy.

Uniquely among authors of naval fiction, Patrick O'Brian's characters develop with experience, and although the Jack Aubrey of Treason's Harbour has a record of successes to equal that of the most brilliant of Nelson's band of brothers, and is no less formidable or decisive in action, he has grown wiser, kinder, and gentler too.

Jack Aubrey's long service is at last rewarded: he is promoted to the rank of Commodore and given a squadron of ships to command. His mission is twofold: to make a large dent in the slave trade off the coast of Africa and, on his return, to intercept a French fleet set for Bantry Bay with a cargo of weapons for the disaffected among the Irish. Invention and surprise follow at every turn in this tale of 19th-century seamanship, as rich, as compelling, and as masterly as any of its predecessors.

Commissioned to rescue Governor Bligh of Bounty fame, Captain Jack Aubrey and his friend and surgeon Stephen Maturin sail the Leopard to Australia with a hold full of convicts. Among them is a beautiful and dangerous spy - and a dangerous disease which decimates the crew.

It is still the War of 1812 and Jack Aubrey - with his tetchy, sardonic friend Stephen Maturin - has set course across the South Atlantic to intercept a powerful American frigate outward bound to play havoc with the British whaling trade. If they do not come up with her before she rounds the Horn, they must follow her into the Great South Sea and as far across the Pacific as she may lead them.

Captain Jack Aubrey, a brilliant and experienced officer, has been struck off the list of post-captains for a crime he did not commit. His old friend Stephen Maturin, usually cast as a ship's surgeon to mask his discreet activities on behalf of British intelligence, has bought for Aubrey his former ship the Surprise to command as a privateer, more politely termed a letter of marque. Together they sail on a desperate mission against the French, which, if successful, may redeem Aubrey from the private hell of his disgrace.

Jack Aubrey and Stephen Maturin, veterans of many battles, return in this novel to the seas where they first sailed as shipmates. But Jack is now a senior Captain commanding a line-of-battle ship sent out to reinforce the squadron blockading Toulon, and this is a longer, harder, colder war than the dashing frigate actions of his early days.
