I read the first book of this series and cannot remember one single thing about it except a vague recollection of meh. I picked this up at the library and found it choppy and slow going at first - but perhaps it's the translation. About halfway through, I found myself becoming more interested and zoomed through in one sitting. That being said, I found the mystery aspect boring and totally uneventful, but I really enjoyed the setting and the description of the time period. Also, I kept envisioning Tom Hiddleston as Mathurin, which made the whole thing a lot nicer and gave me the idea for a new series featuring Loki, a struggling playwright who solves mysteries in Belle Époque France.
