Venona : Decoding Soviet Espionage in America

This extraordinary book is the first to examine the thousands of documents of the super-secret Venona Project -- an American intelligence project that uncovered not only an enormous range of Soviet espionage activities against the United States during World War II but also the Americans who abetted this effort.

The stunning revelations of the Venona papers, only made public in 1995, illuminate in a new way the Stalin era and early Cold War years.
