This book fills in a gap in the annals of Soviet espionage. Clearly, the Cohens contributed much more to the theft of the atomic secret than the Rosenbergs, who were executed. This book was of special interest to me because I got to know Morris and Lona personally while I was in Moscow being prepared by the KGB for undercover work in the United States. The Cohens were absolutely lovely people who were great friends and neighbors. Goes to show you that the old saying ‘Don’t judge a book by its cover’ is very true. Those (honestly) nice people served an evil cause. As much as it might pain one to say that, consequently, they were evil themselves, it is the hard truth.
