One-sentence summary: Police inspector fights conspiracies within police, Paris, personal life.Did I routinely stay up after midnight to keep reading?: Yes.Did this book make me wish my commute were longer?: Yes.Did I nurture a crush on one or more of the characters: Yes. (Roch and Alexandrine, of course!)Trivia gleaned: Sodomy was decriminalized post Revolution!Review: I stayed up until about 3am to finish this book because I was dying to find out how things concluded. Delors has written my favorite kind of historical: rich in detail with interesting characters and a detailed plot that is engrossing. I particularly loved the police procedural angle -- I adore all things Napoleonic, but haven't read a novel that was really set with the citizens. Our hero, Roch Miquel, is maddening and dreamy, which felt very real for me: his youth and experience helped and hindered him through his investigation. Tidbit not relevant to novel but still fun: Author Catherine Delors (@catherinedelors) tweets and she kindly tweeted back with every breathless squee of mine.
