In 1915, a German U-Boat sank the British passenger liner Lusitania. Many Americans, including women and children, were among the 1,200 dead, so the crime caused a storm of protest in America, and helped plunge the U.S. into World War I. In this gripping novel, an insurance investigator and his fiancee help a murdered longshoreman's widow who's been unjustly denied her husband's life insurance. Finding themselves in possession of documents detailing the Lusitania's secret cargo, the couple are targeted by German and British spies, Irish republicans, a rogue socialist, and the newly-formed FBI, all wanting to use the suppressed material for their own purposes.
