Darkness Knows

In the boundless depths of the Langjökull glacier, the frozen body of a businessman, who mysteriously disappeared thirty years ago, is found. The crime remained unsolved at that time. The police have no choice but to re-arrest the seriously ill suspect Hjálmtalín, whom they were never able to lock up. Konraud, a retired police officer, resumes his own investigation into this case, which has troubled him for decades. Before his death, Hjálmtalín asks Konraud to find the real murderer.
