Heinemann, 1st ed., 1989. Viii + 376 pp., diagrams. D.j., 24 x 16cm. Slight lean to front cover o/w FINE. The author of the best-selling book, Most Secret War, draws here on his long experience of intelligence to look at the kinds of problems ' particularly ethical problems ' that intelligence activity can create. He explores each of the topics ' official secrecy, security, deception, command ' in the light of his extensive direct experience in decades when technical developments like radio interception and satellites revolutionised intelligence-gathering. Most Secret War contained an intriguing series of postscripts on intelligence problems raised in that book which could then not fully be explained. Most fascinating of all was the question of who wrote the Oslo Report, the single most important piece of scientific intelligence handed to the British in World War II. This time the author is able to throw important new light on that answer.
