Outstanding read. Most books about Hitler start with his acquisition of power (1932) or the beginnings of WWII (1939). This book, written by his closest friend, offers intimate details of a much younger Hitler and starts in 1922 prior to the Beer Hall Putsch, the prison term and his collection of increasingly radical advisors. The author slowly realizes the monster is friend is becoming and tries, but fails, to keep him grounded. Eventually falling out of favor with the more radical elements of the Nazi party, he has a final break with Hitler and is forced to flee Germany under threat of death.
