The names, we sometimes say, have been changed "to protect the innocent". As regards those agents in KGB networks in the U. S. during and following World War II, their presence and their deeds (or misdeeds) were known, but their names were not. The FBI-KGB War is the exciting, true (which often really is stranger than fiction), and authentic story of how those names became known and how the not-so-innocent persons to whom those names belonged were finally called to account. Following World War II, FBI Special Agent Robert J. Lamphere set out to uncover the extensive American networks of the KGB. Lamphere used a large file of secret Russian messages intercepted during the war. The FBI-KGB War is the detailed (but never boring) story of how those messages were finally decoded and made to reveal their secrets, secrets that led to persons with such now-infamous names as Judith Coplon, Klaus Fuchs, Harry Gold, and Ethel and Julius Rosenberg.
