Frances Thorpe’s life as an assistant editor for the books section of a struggling newspaper is neither exhilarating nor remarkable until a chance encounter on a rainy night changes her life forever.
While driving back to London after a weekend at her parents' home in the country, Frances notices a car that has crashed along the side of the road. After calling for an ambulance, Frances comforts the woman in the driver’s seat, and hears her final words. When the family wants to meet and thank her, Frances resists until she learns that the woman was Alys Kyte, wife of a famous English novelist. After easing the minds of the family members with her account of Alys’s last conversation, Frances strikes up an unlikely friendship with Alys’s daughter, the wealthy, careless and exuberant Polly. As the months go by, Frances gains access to the exclusive world of the literary elite, and becomes irrevocably bound to the Kyte family.
