 PC Rowan is stopped by three children, who claim they have seen a witch. And indeed they find an urn with the remains of on of Kate s former patients Amy Dewhurst, which the mysterious woman threw over the church yard fence. The description of the woman matches Nancy Bellow, the housekeeper and companion of the deceased. Now she cooks for Marjorie Salter, the grand niece of her former employer, and her husband, who are renovating her aunt s old house. The following night the Salters are admitted to hospital with symptoms of food poisoning. Inspector Crossley is so convinced that Nancy Bellow has tried to poison her new employers and murdered Amy Dewhurst that he goes to far to get a confession out of her.
