Biography of a secret agent who was careful to leave few traces behind. The main thing I learned about Virginia Hall is that she was a consummate spook. One of the things that struck me about Hall's undercover work in occupied France was how vital the passive & unorganized resistance of so many of the French people were to the resistance movement. While the danger of informers was ever present & real, the resistance was constantly helped by strangers (even including Vichy police!) either turning a blind eye to their activities or warning them of danger. This is apart from all the people who were willing to actively work for the resistance either for patriotism or money (again, even including Vichy officials & police). I've seen mentions of a possible movie about Hall, but I'm not sure how well her life would translate into the biopic format. Her pre-war foreign service career would be enough for movie in itself. Her wartime service alone would probably take 2 movies to do it justice. I don't like to think of the montage most directors would use for her post-war career doldrums. Overall, a great read!
