An interesting mystery in the vein of Gone Girl and Memento. Maybe I'd have preferred a few less clues so that the culprit would have remained a mystery for longer, but all in all the story was good.
I don't think I liked a single one of the characters, but they definitely conformed to my cynical view of human nature. The insight into an alcoholics mindset was very believable.
All in all, this was a well written and interesting mystery, if not exactly mindblowing. Definitely worth the read.
