The Spycraft Manual
(2005)The Insider's Guide to Espionage Techniques.
A non fiction book by Barry Davies, Oleg Gordievsky and Richard Tomlinson
The Spycraft Manual is unique. There has never been a book that reveals the secret tradecraft techniques used by spies the world over. Until now. Intelligence in the field of counter-terrorism is a different and, in many aspects, arduous and dangerous task. The lives of many agents are in continuous danger. The rules of the game are cruel - as moral and ethical considerations are negated by the bullet. There is no honor between rivals on the streets of Beirut or Baghdad - only the most quickwitted survive. A modern spy must blend in, live among the enemy, speak the language, befriend, and exploit the enemy at very opportunity. They are required to be streetwise, rough, tough, and ruthless.
