'Brilliant, unforgettable ... a masterpiece' New StatesmanWest Germany in the 1960s is a simmering cauldron of radical protests.Amid the turmoil Leo Harting, a Second Secretary in the British Embassy, has gone missing - along with more than forty Confidential embassy files. Alan Turner of the Foreign Office must travel to Bonn to recover them. As he gets closer to the truth of Harting's disappearance, he will discover that the face of Cold War Europe - and the attentions of the British Ministry itself - are far uglier that he could possibly have imagined. Le Carré's searing Cold War novel creates a world where the lines between right and wrong, good and evil, are horribly blurred.
