While relaxing at Brighton's country estate, Carol is contacted by the hippy woman and agrees to meet with them at a secret rendezvous, at the Alexandra Palace in North London. Once there, Carol is attacked by the hippy man in the cellar and chased through the building where she gets attacked by bats in the attic and gets brutally stabbed as the hippy catches up to her on the rooftop. But Carol is rescued by the police, forcing the hippy man to flee. Another red herring emerges when Joan meets with the hippy woman concerning her stepmother's wellbeing and agreeing to meet. The next day, Joan is found murdered in a field with her throat cut. Inspector Corvin meets with Carol recovering at her father's estate to ask about the hippie couple and of the blackmail that Julia Durer may have been planning for Frank. Corvin finally tracks down and arrests the hippie couple, Hubert and Jenny, whom he takes to the scene of the crime to interrogate them about the Durer murder. Although Hubert admits to have stalked Carol and murdered Joan, they protest their innocence claiming not to remember anything about that night except for recalling "a lizard in a woman's skin". Then a phone call comes informing the police that Brighton has been found dead at his estate, the victim of a suicide, and leaving behind a note confessing to the murder of Julia Durer which seems to wrap up the case.
