Booker Prize–winning novelist Penelope Lively’s latest masterpiece opens with a snapshot: Kath, before her death, at an unknown gathering, holding hands with a man who is not her husband. The photograph is in an envelope marked DON’T OPEN— DESTROY.” But Kath’s husband does not heed the warning, embarking on a journey of discovery that reveals a tight web of secrets—within marriages, between sisters, and at the heart of an affair. Kath, with her mesmerizing looks and casual ways, moves like a ghost through the memories of everyone who knew her— and a portrait emerges of a woman whose life cannot be understood without plumbing the emotional depths of the people she touched.Propelled by the author’s signature mastery of narrative and psychology, The Photographis Lively at her very best, the dazzling climax to all she has written before.
