XPD
June 11, 1940 -- where is Winston Churchill? A private aircraft takes off from a small town in central France, while Adolf Hitler, the would-be conqueror of Europe, prepares for a clandestine meeting near the Belgian border. For more than forty years the events of this day have been Britain's most closely guarded secret. Anyone who learns of them must die -- with their file stamped: XPD - expedient demise
