The only thing I remember about this nailbiter was the fire described by the other poster, I think Freya was the one who set her house on fire and perished, maybe this is a spoiler but I'm pretty sure she was the murderess all along. This was probably the scariest easter whodunit ever to air on Norwegian TV, maybe except for "Rød Snø" (Red Snow). I was literally screaming while hiding under the coffee table. Watching either of these scarefests made parental assistance necessary in even the most mundane of tasks, such as entering dimly lit rooms or walking home from a friend's house at night. Pretty lame by today's standards but hey, I was eight.
