The Shanghai Operation

Jake Greenberg, an ex-pat who lived in Shanghai before the Japanese Army marched in, is now a major in the US Army Air Corps serving in China. He is ordered to go behind the lines into the occupied city. Some thing has gone wrong with the escape line that has saved downed American airmen. He is to find out what happened and fix it fast. To do it, Jake and his people must deal with murder, a fractious underground, traitors, and the Kempeitai, the Japanese Gestapo.
