"Spy Book" is the definitive reference to the secret world of dead drops, code names, double agents, and black boxes. With access to previously unavailable archival data, the authors have selected the most fascinating and important people, agencies, operations, terms, and tradecraft.
With more than 2,500 entries, "Spy Book" is a compendium that informs on the informers, from "A-2" (the intelligence staff of the U.S. Army Air Corps) to "Zelle, Margaretha" (Mata Hari's real name). More than 2,000 entries deliver the scoop on agencies, operations, jargon, technology, and even such fictional figures as James Bond.
