The surgeon's mate

The Surgeon's Mate is the seventh historical novel in the Aubrey–Maturin series written by Patrick O'Brian, first published in 1980. The story is set during the War of 1812 and the Napoleonic Wars. Buoyed by victory over an American ship, Aubrey, Maturin and Diana Villiers speed to England on a mail packet that is chased for the papers in Maturin's hands, and possibly for Diana herself. The papers, including a copy of the official report of victory over an American ship, thus arrive in England before the originals, as the packet sailed to outrun the American chasers. Aubrey then commands HMS Ariel for a mission on the Danish coast, which ultimately leads him and Maturin once again to being prisoners of war. This novel was part of the reissue of the series, with copies not always available in the original order written. This was a challenge to readers and reviewers of that time (1990–92), who did not fit this novel into its place in the sequence, suggesting each novel can be read on its own. It was praised as part of "O'Brian's superb series on the early-19th-century adventures" of Jack Aubrey and Stephen Maturin, and specifically marked as "Splendid escape. Literate and amusing.", providing a "look at the darker side of Maturin's life: his work in British intelligence."
