Despite my previous knowledge of her subject thanks to her three previous books as well as those of Giskes and Bleicher, my reading of her pages was quite slow in order to correctly understand her twists and turns. It certainly gave a strong impression of the confusion which no doubt existed both during and after the war when the truth was so hidden and shrouded in lies, deceit, and misunderstanding, both intentional and innocent. Much as I am impressed with her drive, ambition, and unrelenting will to discover the truth and protect Déricourt who she ended up considering a friend, this was too long. She was 74 when it was published and maybe felt it was her last opportunity to set his record straight as she understood it, for posterity. While overall it was an incredible achievement and reflected the many years work she spent trying to ferret out the truth, his and so many others, it fell apart near the end for this reader. As if she lost her perspective in nailing down and presenting the facts but she was significantly older and maybe less wise compared to her younger self writing in the late 1950s when the world was very different. I close the book on J.O.F. and will move on to another author, her friend and colleague I suppose.
