DNF at 20%: the author constantly does things that he thinks makes him sound cool and makes everyone else think he’s a douchebag. I started to get the feeling that this book is more about his own life than about a possible crime, and also that he would not solve the case by the end of the book. After reading other reviews, I decided to not finish this book because my suspicions were correct. Read some of the 1-starred reviews to get a sense of this nonsense.
