Spring of 1800, and Captain Alan Lewrie, fresh from victory in the South Atlantic, is reckoned a hero on a par with Nelson in all the papers. Back in England, he's fitting out his new frigate, HMS Savage, the fruits of that victory, the largest and best-armed frigate he's ever commanded. But you can't leave Lewrie ashore too long without trouble arising.
A Jamaica court has tried him in absentia and sentenced him to hang for the theft of a dozen Black slaves to man his old ship, HMS Proteus. A crime, or was it liberation, as his London barrister argues? The vengeful slaveowner, Hugh Beauman, has come to London to seek Lewrie's end . . . with or without the majesty of the Law!
