This is a big book for scholarly study. It is not an easy read, and it is crammed with facts and very detailed information about the organisation of the SS, the Gestapo, the German Police, and about Himmler's rise and acquisition of more and more power within the Third Reich, yet it sometimes skirts over significant events (like the faked attack at Gleiwitz which precipitated the invasion of Poland). Himmler comes across as a boring sycophantic little pedant - albeit extremely powerful and exceptionally evil, with a pathological hatred of Bolshevism and Jews (which he equated together as the joint evils of the World responsible for the War). It is claimed he was a great organiser, but he spent much of his time organising and re-organising his evil empire with the intention of maintaining and augmenting his own sphere of power, not to make his organisation more efficient. None of his so-called resettlement plans came to anything, and his warped world view condemned millions to death, whilst he showed himself to be a coward by attempting to secure an armistice with the Allies on the Western Front to save his own skin when Germany's fate was sealed. Overall, a well researched and impressive biography about this bizarre little man who became the greatest mass murderer in history. A must read for scholars of Third Reich history. Helpful additional reading "The Himmler Brothers" by Katrin Himmler - this gives a more personal view of Himmler.
