I ordered a new novel, The Patient Ecstasy of Fraulein Braun,” out of horrible fascination and am reading it for the same reason. I knew Eva Braun was Hitler’s niece and companion and imagined the relationship was asexual. Not so, according to Lavonne Mueller’s book. What is true, I don’t know, but there is enough weird perversion to make Fifty Shades readers queasy. We knew the Fifty Shades books were fiction; Braun, Hitler, the Goebbels’ children and all the rest in the bunker are historical. Creepy.
