I had really high hopes for this series, but it's not delivering. Sebastian and Ves should maybe leave investigating to someone who's good at it. In this book, they accuse and physically harm two innocent people wrongly, without properly apologizing or anything. Meanwhile the killer is right in front of them but Sebastian dismisses the suspicion.

Also at the end when they

find the third book and immediately put it in with the others... like, Claude literally told them that's a bad idea. This is gonna bit them in the ass.
