"On December 7, 1941, even as Japanese carrier-launched aircraft flew toward Pearl Harbor, a small American cargo ship chartered by the Army reported that it was under attack from a submarine halfway between Seattle and Honolulu. After that one cryptic message, the humble lumber carrier Cynthia Olson and her crew vanished without a trace, sparking one of the most enduring nautical mysteries of the war. What happened to the ill-fated ship? What happened to her crew? And was she Japan's first American victim of the Pacific War?"--Amazon.com.
