When I was a kid Norwegian Broadcasting used to send mini series of suspense, criminal mysteries and thrills during Easter, and I remember Maelstrom as one of them. I do not recall much of the plot and so on, but I have memories of single scenes that left me terrified and afraid of the dark for months. One of the most disturbing happened when a man went over to the solitary house on the island to investigate, and upon entering the room with all the dolls there was a woman standing behind the door. This woman was very scary. I do not know what here agenda was, but I do remember the whole house being burnt down. I am guessing that the insane female character did that. Although I was very young when I watched this, I do think it was quality TV.
