Ramage and the Freebooters (Lord Ramage Series #3)

Ramage is summoned by the Admiralty and given command of the brig Triton. But like the rest of the navy, Triton's crew has mutinied. Sympathizing with some of their complaints, Ramage also knows that if he fails to deliver three sealed dispatches to admirals off Brest and Cadiz and in the Caribbean, he will become a convenient scapegoat.
