A maritime mystery from Edward Marston, author of the bestselling Railway Detective series.

November 1907. George Dillman and Genevieve Masefield sail from Liverpool on the maiden voyage of the Mauretania. While posing as a passenger George is in fact an undercover detective hired by the Cunard Line. Dillman and Genevieve endure a nightmare voyage during which severe weather batters the vessel relentlessly and keeps the passengers away from the decks. Dillman is instrumental in rescuing a crew member from being washed overboard but he is too late to save one of the First Class passengers from the same fate. At first, it looks like a case of death by misadventure. But Dillman and Genevieve come to realise that it was an act of calculated murder, connected with the presence on board of a record shipment of gold bullion - twelve tons in all - sent from the Bank of England.

At the time of her launch, the Mauretania was the largest moving structure ever built. She would later serve as a WWI hospital and troop ship. After returning to civilian service, Mauretania was retired and scrapped in the mid-1930s.

Previously published under the name Conrad Allen, the Ocean Liner series is relaunched for a new generation of readers.
