Through the dark, icy streets of London flits a man on a mission: he's looking for people to save. So far he's found four - stripped them naked, slit their throats and carefully arranged their bodies so that the arms form the sign of the cross. As the hunt for the killer intensifies, Robert Harvey, the detective assigned to the murder investigation, hides his own sinister secret - one that threatens to surface if the culprit is caught. Part thriller, part detective story, Vengeance is an utterly compelling novel about the nature of revenge. It examines the way our past shapes us, weaving together memory, betrayal and loss.
