Hitler's Hangman: The Life of Heydrich by Robert Gerwarth I read it as an Ebook, but since its a pretty recent publication (2011), I imagine you can find it in bookstores. The book is about the life of Reinherd Heydrich, the true person behind the holocaust. It tells you in sometimes general terms and sometimes specifics about both Heydrich's personal and professional life. It was interesting to actually get a feel of him through his childhood, which would never of lead anyone to think he would become what he did. You got a feel of the kind of personality he had, and how the world around him shaped his world view. If you've read other biographies of Reinherd, theres probably not a whole lot new you'll learn from this book. It's not good with specifics, like how how exactly created his concepts of the camps, just generalities. It was an interesting read, and pretty fast. It claims to be the first real biography of him, and in that it falls kinda short, but if your interested in him, you'll learn something.
