For Andrew Davidson, tragedy marks a turning point… He’s a respected G.P. but when his brother is found with his throat cut, his thoughts turn to anger and revenge. Known villains, who have evaded justice thanks to the efforts of Cairnburgh’s cleverest lawyer, begin to disappear. For rape victim Rhona Kirk, getting on with her life means taking control… She starts a new life in Dundee but haking off her past is difficult, and the men she’s connected with also go missing. When the threats start, she accepts help against her better judgment. For DCI Jack Carston, solving the puzzle is a race against time… He searches for the links between these vanished persons, aware all the time of his own darker impulses and sensing the bond between himself and the vigilante. What he finds is beyond his worst imaginings.
