Here is a fascinating account of America's most sensational spy cases--told bythe FBI agent who helped crack them. The book offers the high drama behind the FBI's efforts to combat German and Soviet espionage in this country, and "reveals much about the inner workings of the Bureau during an era when . . . 'the FBI agent was king'".--Publishers Weekly.
It is simply amazing to me the amount of espionage the Soviet Union had in the 40’s and 50’s, both in the US and worldwide, and the level of high level positions they held in the both England and the US.
