I thought the Dean Koontz novel "Mr. Murder" was an excellent book. It keeps you wondering what's going to happen next. The story line was great because in the world today you never know when somebody could take over your life like this. The book had the main character Martin Stillwater having his life and everything he had worked for ruined because his "evil twin" claimed he was Martin. The story has Martin's family running for their lives until the dramatic end. The book deserved about a 9 from me. The only problem that I had towards the end of the book is it started to get a little bit too long for me.
