[A] destined-to-be classic … Hayder’s work and characters are worth the unending nightmares they will inspire. –The New York Times Book Review Edgar Award winner and international best-seller Mo Hayder is known for her nightmarishly dark, impeccably-plotted thrillers. In Wolf, now in paperback, Hayder ratchets up the terror yet another notch with a bone-chilling novel about a family held hostage in their country home. When a vagrant–the Walking Man, a 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 Detective Inspector Jack Caffery to investigate. Caffery is reluctant to get involved–until the Walking Man promises in exchange new information regarding the childhood disappearance of Caffery’s brother. Meanwhile, the Anchor-Ferrers, a wealthy local family, are fighting for their lives 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, or have they been chosen for a reason?

The home invasion novel to end all home invasion novels … Not unlike John Connolly’s Charlie Parker novels or T. Jefferson Parker’s Charlie Hood books. Wolf is exceptionally original in premise and nightmarish in its rendering. –BookPage

Mo Hayder is a master of ratcheting up tension throughout a book–to the point that one must simply finish it before doing anything else. Such is the case with Wolf. –Deadly Pleasures (Rating: A-)

Mo Hayder’s books featuring Jack Caffery are always an entertaining and engaging read, and this one doesn’t disappoint. –Euro Crime
