In his last days, Adolf Hitler raged in his bunker that he had been betrayed by his own people, defeated from the inside. In part, he was right. By 1945, his armies were being crushed on all fronts, his regime collapsing with many fleeing retribution for their crimes. Yet, even before the war started, there were Germans very high in Hitler's command committed to bringing about his death and defeat.

Paddy Ashdown tells, for the first time, the story of those at the very top of Hitler's Germany who tried first to prevent the Second World War and then to deny Hitler victory. Based on newly released files, the repeated attempts of the plotters to warn the Allies about Hitler's plans are revealed.
