"Deception" is a fascinating look into espionage and counterintelligence during the Cold War. Epstein writes in an engaging style and does a good job of explaining esoteric terms and relating a coherent narrative, while sticking to the sources he has on subjects where the truth is inherently difficult to ascertain. The book also has philosophical and psychological bent; it makes one realize how much of spycraft relies on simple personal relationships and the manipulation of them—trust turning to blind faith, confidence becoming blackmail, little whites lies becoming treason. By this paradigm , the deceived is an active participant in their own deception.
The story is a fascinating one that I was only dimly aware of. The book is very much seen through the eyes of Epstein's key source, CIA counterintelligence chief James Jesus Angleton, who fervently believed that the KGB had deceived, misled, and outfoxed the CIA in throughout the 1960s and up to the present day (in this case, the mid-1980s). All the evidence presented and a bit of common sense leads one to believe that he was right, though hubris led the CIA to believe it could not be deceived. There are several vignettes of Soviet defectors and moles that make compelling reading and support the thesis.
Some of the chapters in the second half of the book expose how hollow the intelligence community's claims that new technology like spy satellites and radio interception made it impossible for them to be tricked by the Soviets—sobering thoughts given the more recent revelations about how the US conducts its electronic surveillance today. The later chapters, which are more forward-looking, have not aged as well, written as they were from the perspective of someone in 1988 who assumed who believed Gorbachev's glasnost and perestroika were merely the latest in a perpetual disinformation campaign by a still-formidable USSR. On the other hand, a quarter-century later, Russia is ruled autocratically by a former KGB officer.
I would recommend the book to anyone with a nostalgic hankering for some Cold War spy intrigue.
