The U.S. State Department thinks Russia has a spy army of 300,000 in its world-wide operations. It is not unreasonable to guess that between 75,000 and 100,000 them are operating inside the U.S. or along its borders. Mentioned in this series are (L-R): Col, Stig Wennerstroem, Col. Rudolf Abel, Harry Gold, Herbert W, Boekenhaupt and capt. Nikolai Khokhlov.
