Charlie's back! Lizbet Lange, who'd forgotten all about him, is abruptly reminded of their past escapade with Charlie's bones when Charlie appears in Lizbet's bedroom at an inappropriate moment. Charlie explains to Lizbet that he needs her help in exposing ten-year-old Rachel Wright's killer back in 1973. Abducted on Halloween, the little girl's body was discovered three days later, but the murderer was never found. It's Halloween again...and Charlie believes that another child might be murdered if Lizbet doesn't step in. Reluctantly, and to her peril, Lizbet agrees.
