In the realm of human behavior, sex can be the catalyst for risky or reckless conduct. The A to Z of Sexspionage explores this behavior through a chronology, an introduction, a bibliography, and hundreds of cross-referenced dictionary entries on the secret agencies, operations, and events. From Delilah's seduction of Samson in 1161 BC to State Department official Donald Keyser's conviction of passing secrets to Isabelle Cheng, a Taiwanese intelligence officer, in 2007, Nigel West recounts the history of sexspionage.
