I bought this book a year ago after hearing the author interviewed on the radio, and finally got around to reading it in the last couple of weeks. It's a big book in so many ways. The early chapters are packed with detail and require concentration, but the work is rewarded on so many levels. The intimacy of the story draws the reader in, the portraits of the real life people are absolutely compelling, and the research is minute and painstaking. The tale of how liars and fantasists came to hold high office, how inept collaborationists ran Vichy France through the war, and how the result was death and persecution on an enormous scale, provides a pertinent warning in this age when the far right is re-emerging across Europe and rewriting its past. Finally, this is the best written use of the English language I have read for a long time. Please read it and learn the lessons. I can't recommend it highly enough.
