It is 1801, and President Thomas Jefferson has assembled a deep-water navy to fight the growing threat of piracy, as American civilians are regularly kidnapped by Islamist brigands and held for ransom, enslaved, or killed, all at their captors' whim.

Fresh aboard the tall-masted Ariadne, Midshipman Lewrie heads for the war-torn Americas, finding - rather unexpectedly - that he is a born sailor, equally at home with the randy pleasures of the port and the raging battles on the high seas. But in a hail of cannonballs comes a bawdy surprise.

The Naval Service of the Honorable East India Company, popularly known as the Bombay Marine, operated in romantic areas in perilous times.

He must navigate the bustle of the town's narrow streets that are busy with legal, illicit and depraved business flowing from and around the ships at dock. But all does not go well; between Betsey's brother and guardian, Henry Tulkington, prohibiting the match and Brazier marked out for trouble by a local smuggling gang, his plans are in disarray.
