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. The chase that follows through the fogs and shallows of the Grand Banks is as thrilling, as tense and as unexpected in its culmination as anything Patrick O'Brian has written. Then, among other things, follows a shipwreck and a particularly sinister internment in the notorious Temple Prison in Paris.
