Query: Without Mercy, murders in Homestead, Florida

This is an excellent book, could not put it down. I live in Homestead, I have never heard of this crime. Everyone I talk to wants to read this book. They have said to me, I can't put this thing down, it is so interesting. Of all the places they describe in the book, landmarks, people and place of business, I know them all. All of these places actually exist. You really need to read this book. I would like to get my hands on the re-trial book !
