The author, a well-known male researcher, opens up a new perspective on Hitler. Every testimony that exists on the private person Adolf Hitler and his sexuality is scrutinised. The result: Hitler was split into the young Hitler 1 and the world politician Hitler 2, aged between 30 and 56. The latter fulfilled all the criteria of a serial killer - a trait that had remained repressed in Hitler 1. But in November 1918, a military psychiatrist made a malpractice mistake - Hitler's "lust for murder" was ignited and Hitler 2, a commanding serial killer, was born.
