When struggling ex-copper Terry Coats was discovered in bed with an air hostess, his excuse that he was 'going undercover' cut no ice with the force - or his wife. But now he is brutally killed on Hogmanay night, it seems there may have been more to his plea. Dragged from the new year celebrations, Special Constable Sir Bob Skinner is shocked to find coats' body alongside that of Griff Montell: his erstwhile protege, and former lover of Skinner's own daughter, Alex. Could there be some dark truth under Coats' cock-and-bull story, after all? As the secrets start unravelling, Skinner realizes he has gravely underestimated someone close to him --and the effects will cost him, and those he loves, dear.
