... from the earliest use of the word "spy" to the latest revelations of the Aldrich Ames case and the post-Cold War reorganization of Russian intelligence apparatus, Spy Book provides the most comprehensive single volume ever published, covering intelligence, espionage, and cryptography. More than 2,000 entries on people, agencies, operations, tradecraft, and tools uncover the secrets of this underground world. The entries include 27 starred (*) "master entries" that cover major spy rings, articles about major countries outlining national intelligence services and activities, and all categories of tradecraft. For example, the entry *Cambridge Spy Ring is cross referenced with entries on the five members of the ring, their principal Soviet handler, and the principal British mole hunter. There are also over 60 illustrations, many published for the first time.
