Query: Wonderful Mystery

I have to say that I enjoyed this book from the beginning to the end. I was with Joe the entire time. I loved the way the book evolved and the fact that I was unable to predict who did it until I read it. I have never read a book so fast before...I finished this book in one day. Vincent keep up the good work and I can't wait for the new book to come out.
