Bruce Wayne is invited to the ancestral castle of the Waynes in England, where he meets several distant relatives and encounters a ghostly knight bent on centuries-old vengeance. When a recently divorced socialite is mysteriously killed by something that literally crushed her head, Barbara Gordon decides to investigate. She soon becomes interested in a wig maker named Vazly and goes to purchase a wig, little knowing that it was Vazly who was responsible for the murder, and that he implanted devices into his wigs in order to extort money from the rich.
