The ring was for his orange headed ex lover and the book is on the psychotic bastard, like a archived forensic report kikifrancis
Also - SPOILER - the friend died (killed by blonde) so he murders the blond guy after a failed attempt where he ends up kidnapped, but manipulated him into a situation where he stabbed him and set the house on fire to get rid of evidence
Anyone could spoil me a little ( i already read the end but didnt read the whole thing xD)
Why is the ring important? Was it from Clark? And whats inside the book?
