21 See Haensel Das Gericht vertagt sich. Ulrich von Hassell noted in The Von Hassell Diaries,1938-1944, entry for 27th March 1939, a remark of Frau Goring according to which Heydrich was 'the devil', Himmler, on the other hand, 'entirely unimportant and basically harmless!' In the same vein see also Schellenberg and Hagen; in a different vein but rather implausible, Edward Crankshaw, The Gestapo.
