"Control" is dead, and George has been forced out of the Circus by the younger generation. When a would-be defector surfaces with a shocking revelation that a Soviet mole, code named 'Gerald' has penetrated the highest level of British Intelligence, it is clear that his treachery has already blown some of its most vital operations and its best networks. George Smiley is assigned to identify and destroy him.. Relying only on his wits and a small, loyal group,Smiley recognizes the hand of Karla—his Moscow Centre nemesis—and sets a trap to catch the traitor. Le Carré's writing, in my view is brilliant, his language and ability to convey the inner workings of the spy industry as a profession is without peer. This is a world-class entertainment and an important, enduring novel, one of the few legitimate classics to arise from the espionage genre. Even on the second reading, the experience was just as enthralling.
