Have read first 100 pages of "The Third Reich in Power." And the truth is indeed more terrifying than fiction. Hitler had at least 85 prominent Germans murdered in 1934 without trial. Included were his predecessor as Reich Chancelor and his wife. And this is what he said after the slaughter:
"If anyone reproaches me and asks why we did not call upon the regular courts for sentencing, my only answer is this: in that hour, I was responsible for the fate of the German nation and was thus the Supreme Justiciar of the German people! ... I gave the order to shoot those parties mainly responsible for this treason."
No evidence of treason was ever offerred against those murdered. So Hitler admitted he alone was judge, jury and executioner. This is the Nazi world if Hitler had won.
