The 1979 murder of schoolteacher Libby Bradley who was stabbed to death in a wooded area is reopened when the victim’s bloodstained jacket is found stuffed in a tree trunk with a happy-face key chain in a pocket. The case was originally investigated by Jeffries when he was a rookie detective. The probe reveals the victim died two months after attending a key party she left with a neighbor, a man with whom she had an affair.
The list of suspects includes the victim’s husband, ex-lover and daughter. Now, Jeffries will go back 27 years and retrace his steps, but as a more experienced detective.
