The German Spy in America / The Secret Plotting of German Spies in the United States and the Inside Story of the Sinking of the Lusitania

Investigative reporting and official documents are combined to portray a domestic network of clandestine agents who engaged in espionage, bribery, sabotage, and plots to place explosive devices on ships and industrial targets. The account recounts prosecutions and intercepted schemes, outlines methods of propaganda and covert influence, and connects these activities to intensified submarine warfare and attacks on passenger shipping. Foreword and introductory material frame the evidence as a call for stricter legal measures and greater preparedness to detect and defend against organized secret operations within national borders.
