In 1915, a German U-boat sank the British passenger liner Lusitania. Many Americans, including women and children, were among the 1200 dead, so the crime caused a storm of protest in America and helped plunge the US into World War I. In this gripping novel, an insurance investigator and his fiancée 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.
I enjoyed the book despite its shortcomings. The plot is a bit thin and some shortcuts are made for it all to come together. The characters could also be a bit more alive and not appear as stiff as they do.
