Quick read, the plot is interesting and the bad guy disgusting, but the final twist is not really unexpected. Since this is the first book by Deflo I've read, I had some trouble relating to the characters. The characters have developed in previous books and it felt like I missed some essential background story to be able to really get invested.
So my advice to other readers would be: start with the first books in which the characters (Dirk Deleu, Jos Bosmans, Nadia Mendonck etc) star and then work your way to this one. This might help you enjoy the book more than I did now.
I would read books by this author again though, because the book read like a train!
