Spycraft

From two men who know how espionage really works, an unprecedented history--heavily illustrated with never-before-seen images--of the CIA's most secretive operations and the gadgets that made them possible. What is an invisible photo used for? What does it take to build a quiet helicopter? How does one embed a listening device in a cat? These may sound like challenges for James Bond's fictional gadget-master Q, but they're all real-life devices created by the CIA's Office of Technical Service. Now, in the first book ever written about this office, the former director of OTS teams up with an internationally renowned intelligence historian to take readers into the laboratory of espionage.--From publisher description.
