A murder on the high seas. A remarkable detective duo. A demon who may or may not exist.



The extraordinary new novel from Stuart Turton, author of the bestselling The 7½ Deaths of Evelyn Hardcastle, winner of the Costa Best First Novel Award.



It's 1634 and Samuel Pipps, the world's greatest detective, is being transported to Amsterdam to be executed for a crime he may, or may not, have committed. Traveling with him is his loyal bodyguard, Arent Hayes, who is determined to prove his friend innocent.



But no sooner are they out to sea than devilry begins to blight the voyage. A twice-dead leper stalks the decks. Strange symbols appear on the sails. Livestock is slaughtered.



And then three passengers are marked for death, including Samuel.



Could a demon be responsible for their misfortunes?



With Pipps imprisoned, only Arent can solve a mystery that connects every passenger. A mystery that stretches back into their past and now threatens to sink the ship, killing everybody on board.
