When Alice Hale leaves a career to become a writer and follows her husband to the New York suburbs, she is unaccustomed to filling her days alone in a big, empty house. But when she finds a vintage cookbook buried in the basement, she becomes captivated by its previous owner: 1950s housewife Nellie Murdoch. As Alice cooks her way through the past, she realises that within the pages Nellie left clues about her life.
Soon Alice learns that while a Baked Alaska may seem harmless, Nellie’s secrets may have been anything but. When Alice uncovers a more sinister, even dangerous, side to Nellie’s marriage, and has become increasingly dissatisfied with her own relationship, she begins to take control of her life and protect herself with a few secrets of her own.
