A good read, alhough I disagree with the review on the jacket that says it's "superior to IN COLD BLOOD in almost every way." The two books are apples and oranges. The story is especially meaningful to me because I was born and raised in the locales where it all happened, and I recognize every landmark mentioned between the covers of the book. On the other hand, the story does not dig very deeply into the WHY of the crime even though it claims that is the reason the book exists. It does give you enough to get you thinking, hard.
