The spies who loved us?

This article appraises the book "The Haunted Wood: Soviet Espionage in America --The Stalin Era," by Allen Weinstein and Alexander Vassiliev. In 1993 Weinstein's publisher paid an organization of former KGB agents an unknown sum of money to grant Weinstein and his collaborator Alexander Vassiliev substantial and exclusive access to Stalin-era operational files of the KGB and its predecessors. Vassiliev, a former KGB man himself, then hunkered down in the reading room of Russia's Foreign Intelligence Service, the KGB's successor organization, to analyze and take notes on whatever tidbits his ex-colleagues decided to proffer.
