XPD

XPD is a spy novel by Len Deighton, published in 1981, and set in 1979, roughly contemporaneous with the time it was written. It concerns a plan by a group of former SS officers to seize power in West Germany, in which they intend to publish some wartime documents about a (fictional) secret meeting between Winston Churchill and Adolf Hitler in June 1940, and the efforts of a British agent, Boyd Stuart, to prevent the documents becoming public.
