Pia and Stefan suspect that Katharina has been spirited away by the supernatural. Their investigation is inspired by the instructive - and cautionary - local legends told to them by their elderly friend Herr Schiller, tales such as that of Unshockable Hans, visited by witches in the form of cats, or of the knight whose son is doomed to hunt forever. Then another girl disappears, and Pia is plunged into a new and unnerving place, one far away from fairy tales - and perilously close to adulthood.
