3.75/5 stars
I'll start by saying I read The Amateurs about a year ago, so I don't remember every single detail. However, the little details they mentioned/remembered throughout this book were enough to help me understand what they were talking about.

I enjoyed this book, not as much as I did the first one, but enjoyed it anyway. It's a light, quick read.
It's obviously a filler: Now the characters (the 'detectives') know who the killer is, and the whole plot revolves around them following up said killer's clues in order to find him and stopping him from killing again. Still, the mistery and feeling of... restlessness, for a lack of a better term, were good enough.

While I don't think this is Shepard's best book or story, I enjoyed it and I'm looking forward to reading the next one(s) and finally learn the killer's motives and how this whole story finally wraps.
