Whenever Elliot Norther’s wife was nervous she baked. With the murder of Harriet Mason, her husband’s close colleague at the Faculty, she had been unable to resist a couple of Victoria sponges. During the frenzied press speculation about the identity of the murderer, a Dundee cake had appeared, followed swiftly by a Battenberg and a Lemon Drizzle. Since news of the Wildencrust murder broke, the kitchen, dining room and study had come to resemble the storerooms of an industrial bakery, every surface heaving with the weight of sponge and cream. Yesterday, having at last been overwhelmed by the fear and rumour that swept the town, she had taken herself off to her mother’s house in Hampstead, leaving her husband to soldier on alone. When he had last seen his wife, Elliot Norther noticed that she had been putting the finishing touches to an impressive, triple-tiered wedding cake, beating a batch of royal icing into a sickly paste.
