TODAY A WOMAN WENT MAD IN THE SUPERMARKET

In December 1926, mystery writer Agatha Christie really did disappear for 11 days. Was it a hoax? Or did her husband resort to foul play?

When Agatha meets Archie on a dance floor in 1912, the obscure yet handsome pilot quickly sweeps her off her feet with his daring. Archie seems smitten with her. Defying her family’s expectations, Agatha consents to marry Archie rather than her intended, the reliable yet boring Reggie Lucy. Although the war keeps them apart, straining their early marriage, Agatha finds meaningful work as a nurse and dispensary assistant, jobs that teach her a lot about poisons, knowledge that helps shape her early short stories and novels. While Agatha’s career flourishes after the war, Archie suffers setback after setback. Determined to keep her man happy, Agatha finds herself cooking elaborate meals, squelching her natural affections for their daughter (after all, Archie must always feel like the most important person in her life), and downplaying her own troubles, including her grief over her mother’s death. Nonetheless, Archie grows increasingly morose. In fact, he is away from home the day Agatha disappears. By the time Detective Chief Constable Kenward arrives, Agatha has already been missing for a day. After discovering—and burning—a mysterious letter from Agatha, Archie is less than eager to help the police. His reluctance and arrogance work against him, and soon the police, the newspapers, the Christies’ staff, and even his daughter’s classmates suspect him of harming his wife. Benedict concocts a worthy mystery of her own, as chapters alternate between Archie’s negotiation of the investigation and Agatha’s recounting of their relationship. She keeps the reader guessing: Which narrator is reliable? Who is the real villain?

A compelling portrait of a marriage gone desperately sour.
