Perfect for you if...

You love crime thrillers where the detective's personal demons are as compelling as the case itself.
You want a home invasion story that goes genuinely twisted rather than predictable.
You've read Hayder before and trust her to deliver the psychological dark stuff without flinching.

Maybe not for you if...

You'd rather skip graphic depictions of family trauma and psychological torment.

About this book

Wolf follows Det. Inspector Jack Caffery when the Walking Man—a recurring character in Hayder's fiction—discovers a dog wearing a collar with a note reading "HELP US" attached to it. Believing someone is in danger, the Walking Man contacts Caffery to investigate. Caffery is initially reluctant, but the Walking Man offers information about Caffery's brother, who disappeared during Caffery's childhood. Uncertain of what he is searching for, Caffery realizes he is in a race against time. Meanwhile, the Anchor-Ferrers, a wealthy local family living in a remote home ten miles away, are held hostage and fighting for their lives. As their ordeal becomes increasingly bizarre and humiliating, the family questions whether this is truly a random crime. The novel centers on a home invasion and the interconnected fates of those involved.
