The Lusitania Murders — Max Allan Collins

On May 7, 1915, the luxury liner Lusitania was struck by-a German torpedo. Sinking within eighteen minutes--and claiming the lives of twelve hundred people--it was a pivotal event of the First World War that has been shrouded in mystery...

Critic and journalist Willard Wright could hardly refuse an undercover assignment aboard the Lusitania. The one proviso: He would have to travel incognito, using the pseudonym S.S. Van Dine. Ostensibly, his job was to interview the ship's rich and famous passengers. But, unbeknownst to one of his employers, Van Dine had been sent to investigate the possible transportation of munitions for the war effort. And when six of the passengers receive telegrams warning them that the liner was about to be targeted, Van Dine sensed this would be no ordinary voyage but a passage into the pages of history.
