内容简介：
During World War II, Ben Hartley, a brilliant young electronics design engineer, is suddenly drafted by the Corps of Engineers to design surveillance systems for their counterintelligence group. Ben is taken from a quiet life of research and thrown into a world of espionage, violence and beautiful women. His new job will require not only his genius for design, but also his stubborn tenacity and sharp wit, to thwart a German spy network trying to steal information on the new low light vision equipment. While doing that he must also find a rogue colonel selling secret information to the Germans and uncover a German surveillance post that is actually operating on the military base. His life hangs in the balance as enemy agents attempt to prevent him from finding a solution.
