I only gave this book a one star because I could not give it anything lower. I am convinced Patterson does absolutely no research for his books. However, this is one of the worst offenders of his books. Patterson's plots using Cross are getting more and more far-fetched. It is reasonable to have one serial killer obsessed with Alex Cross but four or more get real. I also have a lot of trouble believing that no physical evidence would be found at a crime scene. This book was horrible poorly written and researched. If you like reading tripe this is the book for you.
