The World Was Going Our Way: The KGB and the Battle for The Third World

In 1992 the British Secret Intelligence Service exfiltrated from Russia a defector whose presence in the West remained a secret until the publication of The Sword and the Shield in 1999. That man was Vasili Mitrokhin, the KGB's most senior archivist. Unknown to his superiors, Mitrokhin had spent over a decade making notes and transcripts of highly classified files which, at enormous personal risk, he smuggled out of the KGB archives. The FBI described the archive as "the greatest single cache of intelligence every received by the West."
