勒卡雷一生得奖无数，包括1965年美国推理作家协会的爱伦坡奖，1964年的英国毛姆奖、James Tait Black纪念奖，1988年获颁英国犯罪推理作家协会（CWA）终身成就奖，即钻石匕首奖（另外在1963年与1977年两次获颁匕首奖），以及意大利Malaparte Prize等等。2005年，CWA更是将其最高荣誉“金匕首奖中之奖”授予勒卡雷。至今已出版20部作品，已有11部被改编为电影和电视剧。

John le Carre'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 Carre 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.
