George Smiley

Alec Leamas is tired. It's the 1960s, he's been out in the cold for years, spying in the shadow of the Berlin Wall for his British masters. He has seen too many good agents murdered for their troubles. Now Control wants to bring him in at last - but only after one final assignment. He must travel deep into the heart of Communist Germany and betray his country, a job that he will do with his usual cynical professionalism. But when George Smiley tries to help a young woman Leamas has befriended, Leamas's mission may prove to be the worst thing he could ever have done.

When the Department - faded since the war and busy only with bureaucratic battles - hears rumours of a missile base near the West German border, it seems the perfect opportunity to regain some standing in the Intelligence world. Desperate for glory and determined to outdo their rivals at the Circus, including George Smiley, they send deactivated agent Fred Leiser back into East Germany, armed only with some schoolboy training and his memories of the war. In the land of eloquent silence that is Communist East Germany, Leiser's fate is no longer his own.

A mole, implanted by Moscow Centre, has infiltrated the highest ranks of the British Intelligence Service, almost destroying it in the process. And so former spymaster George Smiley has been brought out of retirement in order to hunt down the traitor at the very heart of the Circus - even though it may be one of those closest to him.
