The Edgar Award–winning, internationally bestselling author delivers a bone-chilling novel about a family held hostage in their country home. Wolf kicks off when a vagrant—the Walking Man, an enigmatic, recurring character in Hayder's fiction—finds a dog wandering alone with a scrap of paper with the words "HELP US" attached to its collar. He's sure it's a desperate plea from someone in trouble and calls on Det. Inspector Jack Caffery to investigate. Caffery is reluctant to get involved—until the Walking Man promises to exchange new information regarding the childhood disappearance of Caffery's brother. Caffery has no idea who or what he is searching for, but one thing he is sure of: it's a race against time. Meanwhile, the Anchor-Ferrers, a wealthy local family, are fighting for their lives, held hostage in their remote home ten miles away. As their ordeal becomes increasingly bizarre and humiliating, the family begins to wonder: Is this really a random crime? "The home invasion novel to end all home invasion novels . . . Wolf is exceptionally original in premise and nightmarish in its rendering."— BookPage
