The second book in the Frost series brings up the Inspectors tragic past. His sisters killer is released due to planted evidence. Not only is he released but Frost is the one that discovered the dodgy evidence. It then becomes a race against time to find new evidence to lock him up before he kills again.

This book is a bit different because we know who the guilty party is. You get to experience the stress of trying to find new evidence and stop him killing again. We all know it's inevitable that he will kill. I kind of expected one of the murders but it still broke my heart a little bit. The ending is also pretty sad and the action keeps going until the very last chapter. I really like the main characters and I am definitely invested in their lives.
