West Germany, a simmering cauldron of radical protests, has produced a new danger to Britain: Karfeld, menacing leader of the opposition. At the same time 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, facing riots, Nazi secrets and the delicate machinations of an unstable Europe in the throes of the Cold War. As Turner gets closer to the truth of Harting's disappearance, he will discover that the face of International relations — and the attentions of the British Ministry itself — is uglier that he could possibly have imagined.
