A mother calls for her child repeatedly in the soft summer air, her voice rising with panic, her eyes searching the dark waters of the loch. Her only child is missing, and nothing will ever be the same again. The disappearance of a three-year-old girl from her isolated Highland home one summer shook the nation. A massive police search involving divers in the loch and dogs combing the moorland and mountains had failed to find Lily Masterton. Three years later, her grief-stricken parents hire Private Investigator Teàrlach Paterson - an expert in finding missing children - to bring their precious Lily home. As Teàrlach pieces together the secrets at the heart of the Masterton family, tiny bones are found in the loch close to the Masterton's home. Could they be Lily's? Or will Teàrlach unravel a truth even more shocking?
