Book excerpt: In January 1941, Noel Annan was assigned to Military Intelligence in Whitehall, where he was to be involved for the next four years, at the center of Britain's secret war planning, in the crucial work of interpreting information supplied by a network of agents throughout occupied Europe. When the war in Europe ended, Annan was seconded to the British Zone in defeated Germany to help rebuild its ruined cities. Annan got to know the new generation of German politicians who were to bring about the economic miracle that led from the ashes of defeat to Germany's renaissance as the most powerful nation in Europe. When the future chancellor Konrad Adenauer was placed under house arrest and banned from taking part in politics, Annan helped to get him released. Annan's riveting account of this pivotal period of European history is both fascinating in itself and of considerable importance to our understanding of Europe today.
