Ghosts of Honolulu<br /><br />Ghosts of Honolulu: A Japanese Spy, a Japanese American Spy Hunter, and the Untold Story of Pearl Harbor&quot; by Mark Harmon and Leon Carroll, Jr. is a non-fiction book that delves into the world of espionage in Hawaii during World War II.&nbsp;<br /><br />The book highlights the work of the precursor to the Naval Criminal Investigative Service (NCIS) in combating Japanese spies. A significant figure in the narrative is Douglas Wada, the only Japanese-American counterintelligence agent in Hawaii at the time.&nbsp;<br /><br />Wada&#39;s task was to monitor the local Japanese population, although he and his colleagues primarily focused on the Japanese consular agents as the real spies. The book describes the covert activities and challenges faced by Wada and his team, especially after the Pearl Harbor attack, which was facilitated by information from a spy in the Honolulu consulate.&nbsp;<br /><br />Grab a copy and learn more!
