Тьма знает

In the immense depths of the Langjökull glacier, the frozen body of a businessman, who disappeared without a trace 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 Hjalttalin, who was never able to be imprisoned. Konraud, a retired policeman, resumes his own investigation into this case, which has haunted him for decades. Before his death, Hjalttalin asks Konraud to find the real murderer and avenge all the suffering that torments his soul. One night, a drunken woman comes to Konraud with strange, frightening information obtained from her tragically deceased brother, and finally, a new lead emerges that could lead to the real criminal. But will Konraud have the strength to uncover the terrible secrets that have accumulated over the decades and the brutal truth that could destroy many lives?
