is an historical novel by Dudley Pope, set during the French Revolutionary Wars.

Ramage's ship, HMS Triton, is performing guard duty to a merchant convoy travelling from Britain to Jamaica.

An otherwise routine assignment is complicated by his being under the orders of Rear Admiral Goddard, his family's sworn enemy.

A side-plot occurs when Triton is wrecked on a remote island, Isla Culebra.

Successfully taking the Spanish forces prisoner, Ramage turns his wits to solving the puzzle and eventually triumphs through a combination of clear thinking and good fortune, recovering a large quantity of gold and precious stones which he delivers to the British authorities on leaving the island.
