A brilliantly original thriller and "a startling, smart, vivid book" (Tana French, New York Times bestselling author) from the acclaimed author of Three Graves Full--inspired by the real-life unsolved theft of a seventeenth-century painting. Twenty-eight seconds. In less than half a minute, a home-security camera captures the hidden resolve in fourteen-year-old Carly Liddell as she fends off a vicious attack just inside her own front door. The video of her heroic escape appears online and goes viral. As the view count climbs, the lives of four desperate people will be forever changed by what's just barely visible in the corner of the shot. Carly's stepfather is spurred to protect his darkest secret: how a stolen painting--four hundred years old, by a master of the Dutch Golden Age--has come to hang in his suburban foyer. The art dealer, left for dead when the painting vanished, sees a chance to buy back her life. And the double-crossed enforcer renews the hunt to deliver the treasure to his billionaire patrons--even if he has to kill to succeed. But it's Carly herself, hailed as a social-media hero, whose new perspective gives her the courage to uncover the truth as the secrets and lies tear her family apart.
