I'm a sucker for a murder mystery and psychological thriller. But this was longer than it needed to be. I think this could have been a book half the length. There was so much prattling on, usually Hannah's inner monologue. Which became repetitive. I was wrong about whom the killer was; that is to say there was great misdirection as is customary for stories of this kind. I really wish it wasn't such a slow pace until the last 5% of the book. I listened to the audiobook at 3x speed and it still took me much too long to finish.
