Book excerpt: The young lawyer Peter Martin is invited by his girlfriend to spend Christmas in the family mansion of her parents in the cold lands of the north of Scotland, on the shores of the famous Loch Ness. What seems to be a pleasant gathering of relatives and friends to celebrate some lovely parties, will unexpectedly turn into a terrible nightmare. Screams of horror and despair will soon echo in the labyrinthine corridors of the house. Some of the most prominent members of the family will suffer the fierce attacks of an unknown hidden murderer. The police are bewildered, without a logical lead to follow, and the inhabitants of the house feel helpless. All the occupants of the old mansion are suspects, servants, relatives and friends, even the local police chief, in charge of the investigation, may have his ulterior motives. These bloody crimes evoke an ancient and sordid legend ... Something emerges from the mist is a story from the Suspense and Intrigue Stories collection, a series of stories written by the author in tribute to the Mistress of suspense Agatha Christie.
