Upon Heydrich’s death, Hitler had his safe blown open and acquired the documents therein. With incredible anger and agitation, Hitler read Heydrich’s big file named Adolf Hitler. When he was finished, he shouted like a madman and told Bormann, “Heydrich was more dangerous that we thought! He had us all within the grasp of his hands!!! What would have happened to us had he lived!?”
