On October 17, 1995, I was invited to the post-modern London headquarters of the Secret Intelligence Service (better known as SIS or MI6) at Vauxhall Cross on the banks of the Thames to be briefed on one of the most remarkable intelligence coups of the late twentieth century. SIS told me how in 1992 it had exfiltrated from Russia a retired senior KGB archivist, Vasili Mitrokhin, his family and six large cases of top-secret material from the KGB’s foreign intelligence archive. Mitrokhin’s staggering feat in noting KGB files almost every working day for a period of twelve years and smuggling his notes out of its foreign intelligence headquarters at enormous personal risk is probably unique in intelligence history. When I first saw Mitrokhin’s archive a few weeks after the briefing, both its scope and secrecy took my breath away. It contained important new material on KGB operations around the world. The only European countries absent from the archive were the pocket states of Andorra, Monaco and Liechtenstein. (There was, however, some interesting material on San Marino.) It was clear that Mitrokhin had had access to even the most highly classified KGB files — among them those which gave the real identities and “legends” of the Soviet “illegals” living under deep cover abroad disguised as foreign nationals.[1]
Soon after my first examination of the archive, I met Vasili Mitrokhin over tea in a conference room at SIS headquarters and discussed collaborating with him in a history based on his material. Mitrokhin said little about himself. Indeed it later required some persuasion to convince him that it was worth including his own story at the beginning of our book. But Mitrokhin was passionate about his archive and anxious that as much of it as possible be used to expose the record of the KGB.
Early in 1996 Mitrokhin and his family paid their first visit to Cambridge University, where I am Professor of Modern and Contemporary History. I met them outside the Porters’ Lodge at Corpus Christi College, of which I’m a Fellow, and we had lunch together in a private room overlooking the medieval Old Court (the oldest complete court in Cambridge). After lunch we went to the College Hall to look at what is believed to be the only surviving portrait of the College’s first spy and greatest writer — the Elizabethan dramatist Christopher Marlowe, who had been killed in a pub brawl in 1593 at the age of only twenty-nine, probably while working for the secret service of Queen Elizabeth I. Then we walked along the Backs through King’s and Clare colleges to visit Trinity and Trinity Hall, the colleges of the KGB’s best-known British recruits, the “Magnificent Five,” some of whose files Mitrokhin had noted.[2] Mitrokhin had long ago mastered the art of being inconspicuous. The friends and colleagues whom we met as we walked round Cambridge did not give him a second glance.
In March 1996 the then Foreign Secretary, Malcolm Rifkind, gave approval in principle (later confirmed by his successor, Robin Cook) for me to write a book based on Mitrokhin’s extraordinary archive.[3] For the next three and a half years, because the archive was still classified, I was able to discuss none of it with colleagues in Corpus Christi College and the Cambridge History Faculty-or even to reveal the nature of the book that I was writing. In Britain at least, the secret of the Mitrokhin archive was remarkably well kept. Until
The secret of the Mitrokhin archive was less rigorously preserved by some of Britain’s allies. But though there were a few partial leaks by foreign governments and intelligence agencies which had been given access to parts of the archive, none had much resonance in Britain. In December 1998, I received out of the blue a phone call from a German journalist who had discovered both the codename by which Mitrokhin was known in Germany and the contents of some fragments of Mitrokhin’s German material. He told me he knew I was completing a first volume based on the Mitrokhin archive and had already planned a second. For the next few months I expected the story to break in the British press. Somewhat to my surprise, it did not do so.
