The Darkening Sea (Volume 20) (The Bolitho Novels, 20)

Soon after taking part in the dramatic capture of Martinique in the Caribbean, Vice-Admiral Sir Richard Bolitho is next despatched to the African coast to gather a flotilla and stop French attacks on British trade routes. But Bolitho must contend with more than Britain's old enemy—he must also face the hatred of his flag captain and betrayal by a man he once counted on as his friend.
