A woman swims in a remote, milky-blue lagoon. Steam rises from the water and as it clears, a body is revealed in the ghostly light. Miles away, a vast aircraft hangar rises behind the perimeter fence of the US military base. A sickening thud is heard as a man's body falls from a high platform. Many years before, a schoolgirl went missing. The world has forgotten her. But Erlendur has not.
