A wounded man walks into a police station and tells a remarkable story. He was picked up while hitchhiking, drugged, and woke up in chains in a barn. He'd been kidnapped by a man named Heath, who explains he's going to make Gabriel his 55th victim. But Gabriel managed to escape. The next day, a man calling himself Heath walks into the same police station and tells the exact same story. Except in his version, he is the victim. And Gabriel is the killer. A brilliant debut thriller with a shocking ending.
