Taking off his cloak and deprived of his dagger, the former chief of our central Intelligence Agency gives a history of this crafty craft. Although his ain purpose is a frank defense of CIA's activities and general policy, he has also ound room for a chronology of espionage and national security which takes in every py case of importance from the deputation Moses sent into Canaan to the Profumo- vanov-Keeler scandal. Aside from the few terse autobiographical remarks, the sections which readers should find most fascinating deal with clandestine intelligence-gathering as a trade: what types of sources can be trusted, how ""plants"" are ade, and all the ingenious rules of the game. In his final chapters, where he akes brief hold of such touchy questions as just how to maintain security in a ree society and how the CIA relates to our individual freedoms, Mr. Dulles shows hat a professional he really is. There is a categorical denial of CIA interference policy-making (i.e. the Bay of Pigs fiasco) and he warns that ""the last thing we an afford to do today is to put our intelligence in chains""... Both the Dulles' ame and the material should enlist considerable attention and interest.
