'An outstanding thriller . . . The pace is beautifully judged, and though there are plenty of twists and turns, the reader never feels left behind'
Undiscovered Scotland

On holiday in the Scottish Highlands, forensic scientist Dr Rhona MacLeod joins a mountain rescue team on Cairngorm summit, where a mysterious plane has crash-landed. Nearby, a climbing expedition has left three young people dead, with a fourth still missing.

Meanwhile in Glasgow, DS Michael McNab's raid on the Delta Club produces far more than just a massive haul of cocaine. Questioning one of the underage girls found partying with the city's elite, he discovers she was smuggled into Scotland via Norway, and that the crashed plane may be linked to the club.

Joined by Norwegian detective Alvis Olsen, who harbours disturbing theories about how the two cases are connected with his homeland, Rhona searches for the missing link. What she uncovers is a group of ruthless people willing to do anything to ensure the investigation dies in the frozen wasteland of the Cairngorms . . .
