James Patterson is an interesting writer. This is an interesting book by this author. Two serial killer's link two officers together to find out who is the Joh O'Hara serial killer, (A serial killer goes around murdering people called John O'Hara). Another serial killer kills newlyweds on their honeymoon The honeymoon killer is kind of twisted but interesting. This book was hard to put down. It was a page turner with its twist and turns and James Patterson did a good job. The book gets confusing at first but it makes sense later on.
