This was my first Michael Connelly book and I found the story and the characters very intriguing. One thing that I found refreshing was the prose detailed the criminal investigation. Several items were pursued in detail and found out to be dead ends. This made the twists and turns that more engaging as not all the information presented was relevant. The story revolves around retired detective Harry Bosch who returns to the force to help close cold cases. The case he starts with recently recieved a DNA match that was not possible when the case first presented itself. I enjoyed the book and look forward to reading more Connelly novels.
