Despite the Burgess and Maclean affair, the Americans had decided that co-operation was safe once more, and the tunnel was a joint CIA/MI6 project using British expertise from a prototype in Vienna.
This was a mistake: there was another mole in the British secret services, and the KGB knew about the tunnel even before it was built.
Why the KGB kept the secret to itself is one of the puzzles explored in this book.
Was it inter-service rivalry?
Was the British mole so valuable that the KGB sacrificed Red Army secrets rather than blow his cover?
Or, since the Russians in fact had no plans to attack the West, did the KGB want that information leaked to reduce the risk of surprise strikes the other way?
Spies Beneath Berlin draws on eyewitness interviews and the full range of sources.
Praise for Spies Beneath Berlin:
'A remarkable book . . . which reminds us of something we should never forget - how a few outstanding Britons and Americans helped to preserve the peace, security and freedom of the West in the harshest years of the Cold War' - Oleg Gordievsky
‘Spies Beneath Berlin delivers surprise after surprise and makes all previous accounts of this amazing story quite obsolete.
It's a real page turner too - I read it virtually at a sitting' - Len Deighton
'Impeccably convincing . . . as exciting as a good detective story'
- The Spectator
