Although Madame Fourcade seems to have been an admirable character I found this book boring beyond belief. I read only non-fiction including biographies of obscure royal personages. It is exceedingly rare for me to abandon a book one-third of the way through as I did with this book. Unlike other spy stories where there might be some amusing aspects e.g. Macintyre's "A Spy Among Friends" or an element of suspense, this book is as dry as an old bone.
I am always leery too of stories about the French Resistance movement. If one is to believe General de Gaulle France during the war years was replete with thousands of resistance fighters. While there were some, the French by and large found collaboration with the Nazis to be a very comfortable way of life even prior to the occupation. The Nazi occupation removed those old-fashioned ideas and concepts of Liberty, Equality and Fraternity and replaced them in France with a dictatorship that was far worse then was ever seen under the Bourbons and with which the French by and large seemed very comfortable. Social life in Paris went on with French high-society people partying with Nazi bosses like Otto Abetz.
The heroes of that time at least to the French included members of the Vichy government especially Marshal Petain who instituted anti-Jewish measures long before the Nazis even asked him to do so. It took decades for a French government to even acknowledge that the French during the war were highly complicit in the deportation of even children to die in Auschwitz. Madame Fourcade was clearly an exception to the general French complicity with the Nazi occupation. However, the author of this book has not done her any posthumous favors in writing her story.
