Negative Positive
Title: remarkable research
Review: Kern has done a remarkable job with this very difficult subject. I have read many books about Soviet spies, but this is by far the best one, in terms of the depth of understanding of the political system in the Soviet Union at the time. The portrait of American leftists and bureaucrats is priceless. This author has brought rigorous logic and impeccable scholarship to this field. All this, and it reads like a mystery.
