Sergeant Alan Murray's wife Sheila disappeared on Ardnabrone Mountain several years ago and despite several investigations no trace of her was ever found. When DS Lee Sheridan is assigned to revisit the case, Murray is sceptical. The locals will hardly take a city girl, a stranger, into their confidence, he feels. But just as he has convinced himself that Lee is wasting her time, human remains are discovered on Ardnabrone Mountain. Could this be the lead they have all been looking for?
