Be prepared to stay up reading into the wee hours once you get your hands on this book. It held my interest better than any novel, and it filled in all the gaps in my understanding of how Hitler was able to gain so much power so quickly, with so little opposition. Erik Larson used the detailed diaries of William E. Dodd and his daughter Martha to reconstruct "a year in the life" for Americans in Berlin from 1933 to 1934.William Dodd had no idea what he was saying yes to when President Roosevelt offered him the position of ambassador to Germany in 1933. Dodd had fond memories of the Germany of 40 years before, when he'd attended college in Leipzig. Upon arrival in Berlin, he and his family discovered a Germany already in the grip of terror, a mere six months after Hitler had been appointed chancellor. Storm Troopers were attacking people in the streets. Communists and liberals were already being sent to concentration camps without due process. As ambassador, Dodd found he was required to attend diplomatic functions and rub shoulders with the monsters of the new regime. As the horrors worsened, he found this increasingly repugnant, and tried doggedly to convince those in Washington that intervention was necessary. His entreaties fell mostly on deaf ears. Dodd's bosses were more concerned about getting Germany to pay off their huge debt to America, while maintaining an isolationist position with regard to foreign conflicts. While Dodd struggled with his diplomatic duties, his young daughter Martha was treating her time in Berlin as a lark. She dated and consorted with highly placed Nazis, including some of the most abominable of Hitler's minions. At first, she enthusiastically endorsed the Nazi agenda and its effect on the "New Germany." By the winter of 1933-34, however, she too was living in terror. This didn't seem to put much of a damper on her dating life, though, and she gained a reputation as quite a round-heeled girl. In late June of 1934 came "The Night of the Long Knives," in which Hitler orchestrated the rapid execution of hundreds of Storm Troopers and other "enemies," some seemingly at random. That August, President Hindenburg died. Hitler quickly took control and achieved absolute power. William Dodd remained in his position as ambassador for three more years, during which American leaders continued to refuse his requests for intervention in Nazi Germany.This book has already earned a permanent place in my home library. I can't recommend it highly enough. Great care has been taken to provide all the little things that prevent confusion and make a book easier to read and understand. I would give it six stars if I could.
