There was a lot of potential with the setup of this book, but it ended up boring me. If you're familiar with this genre at all, you know exactly who the culprit is from the moment the incident occurs, but there's still some hundred pages of "mystery" as the protagonist tries to piece together the obvious. Plus, much like Girl on the Train, we're subjected to the evil villain monologue once the big reveal happens. That cheap caricature of the baddie is so old, and it's one of my least favorite devices. A quick read, but not a memorable entry into the effed-up-women mystery genre.
