Tinker, Tailor, Soldier, Spy

John le Carré's classic novels deftly navigate readers through the intricate shadow worlds of international espionage with unsurpassed skill and knowledge and have earned him -- and his hero, British Secret Service agent George Smiley -- unprecedented worldwide acclaim.
A modern masterpiece in which le Carré expertly creates a total vision of a secret world, Tinker, Tailor, Soldier, Spy begins George Smiley's chess match of wills and wits with Karla, his Soviet counterpart.
It is now beyond doubt that a mole, implanted decades ago by Moscow Centre, has burrowed his way into the highest echelons of British Intelligence. His treachery has already blown some of its most vital operations and its best networks. It is clear that the double agent is one of its own kind. But which one? George Smiley is assigned to identify him. And once identified, the traitor must be destroyed.
