Such a disappointment! Such a well-written premises and hook but the book is a total letdown. There were tons of sections that added nothing to the story and seemed like filler. Not to mention of the guy's own personal case of his friends go missing to not even be solved and have nothing to do with the other case, it was all a big let down... 
 In addition the guy was a pretty shitty detective and an overall guy.. Man, if he was my employee I would fired him a long time ago. The narrator was just overall sucky and it made the book even worse.
