What’s ironic is that very few in the Nazi hierarchy, save Hitler, shed tears over Heydrich’s demise. Himmler despised him, but was scared of him.
My information was the Himmler kept the rumor of Heydrich’s Jewish blood as a way to keep him ardent in his work.
A “make him prove his is not” by being “extra zealous.” Hitler used that tactic too, on some of his “justice ministers.”
So I have been told.
