An atmospheric and immersive Agatha Christie-style historical crime fiction retelling of the sinking of the RMS Lusitania as it sailed from New York to Liverpool in 1915.

Welcome on board the Lusitania’s final voyage . . .

New York, 1915. RMS Lusitania, one of the world’s most luxurious trans-Atlantic liners, departs for Liverpool and war-torn Europe. Among those on board is Patrick Gallagher, a civil servant in Her Majesty’s government tasked with discreetly escorting a British diplomat back to England in relation to charges of suspected treason.

When a fellow passenger, Jimmy Dowrich, is found shot to death in his cabin, the captain asks Gallagher to investigate. Knowing something of the man’s past, Gallagher realizes that the problem will not be simple; and also, the body was discovered in a locked cabin with the key inside and no gun to be found.

Gallagher believes that one of his fellow passengers is a deadly killer. But many of those on board are harbouring secrets of their own, and his questioning reveals that several had a motive for ending Dowrich’s life. He fears that the killer could strike again to protect their true reasons for being on board and all the while, the ship sails on towards Europe, where deadly submarines patrol the war zone . . .
