Here is a very good adventure that recently appeared in Fudge Factor. Being that it is written for Fudge, it would be pretty easy to adapt. It is well worth checking out.
Fudge Factor: Kilbrandeen House
"Sitting high up on a hill, on the outskirts of Scotland, there sits Kilbrandeen House. This abandoned house has held the town in awe with legends and mysterious happenings for the last 200 years.
Enter, if you dare."
