Paul Mazarelle is a police investigator that has his work cut out for him. Not only is he working a case but he's trying to solve his own problems as well.
I found this book with all of it's twists and turns to be a refreshing change from some of the other.
The world building in my opinion was amazing, I could see in my mind the catacombs.... not that that's something I want to see but the descriptions were so vivid and detailed that I could imagine the locations that were being written about.
I do question quite a few of the Mazarelles decisions, like becoming friends with one of the suspects, I mean ok so he wasn't sure who was who at that point but that's kind of the point.
I will say I didn't see the identity of the murderer, it snuck up on me but once the true sequence of events was revealed it made all of the pieces fall into place and that in my opinion is the best kind of mystery. When all the pieces click and you just sit back and think wow how did I miss all of that.
