I am a mystery novel addict. I had heard from the members of my book club just how great this book really is. I bought it and figured that I had just an hour available to begin reading it. Eight hours later I put the book down after reading it from cover to cover. (I rescheduled an appointment with a client until the next day because I refused to stop turning the pages.) And this is from a guy who has been feeling that there are no new literary twists out there for me anymore. Was I in for a great surprise. On a scale of 1 to 5, this one is a 6.
