Berlin, 1934. Adolf Hitler has been Chancellor of Germany for just over a year. On 30 June 1934, he launches the Night of the Long Knives: Ernst Rohm, leader of the Nazi storm-troopers is struck down, along with scores of his leading officers. But the killing doesn't stop there. The operation is directed by SS-chief Himmler and his deputy, Reinhard Heydrich, and they use these hours of pitiless violence to settle some old scores. Klaus Bruckenstatt is an agent in Heydrich's security service, the SD. His surveillance work draws him into the midst of the bully-boys of the SA, until things go badly wrong and he is hastily transferred. His new subject has far more political cunning than Rohm. On 30 June 1934, Bruckenstatt finds himself a party to the most outrageous of all the killings done during the Nazi purge. In this book he reveals what really happened that day in Potsdam.
