I have to say I read this book in 2 days (and it isn’t a short book). The story gripped me right from the start and it was great to see the changes in the eponymous main character. Lucien Bernard is a struggling architect in Paris during WWII and is asked by a client to devise a hidden hiding place that could hold a person. He realizes that it is probably for a Jew (he has ambivalent feelings about Jews) but he needs the money so he does it. As the book goes along Lucien comes to realize that he is actually saving people’s lives and it affects him deeply. There are a lot of tense moments in the story that keep one turning the pages. I would highly recommend this book.
