Virginia Hall is an American from Baltimore, for her France is a second home. Virginia volunteers to work with the SOE and the OSS to coordinate the response of the French Resistance with the Allies, prior to D-Day.
Vicary is a spy catcher – he does his job well until realizing that a small group of German sleeper agents trained by Abwehr officer Kurt Vogel are still in Britain. The threat is that the German agents could discover the secrets to the invasion and allow the Germans to setup a proper defense line (or call the invasion off) and the invasion would fail.
The book simply didn’t speak to me. I couldn’t feel sorry for the author, maybe because the story of her divorce isn’t complete and the missing pieces seem essential to understanding the tragedy (not to mention all the guilt she felt without really explaining why).
