Two days before Christmas, a young woman is found dead beneath the cliffs of the deserted village of Kalfshamarvik.

Did she jump, or did something more sinister take place beneath the lighthouse and the abandoned old house on the remote rocky outcrop? With winter closing in and the snow falling relentlessly, Ari Thor Arason discovers that the victim’s mother and young sister also lost their lives in this same spot, 25 years earlier.

As the dark history and its secrets of the village are unveiled, and the death toll begins to rise, the Siglufjordur detectives must race against the clock to find the killer, before another tragedy takes place.
