Here's another post in - ahem - the spirit of the season: a scenario I whipped up for a recent session of Call of Cthulhu: In the deep woods of northern Massachusetts, the PC's (or, since this is CoC, the "investigators") are about to become embroiled in a family's dark and deadly secret... will they survive the "Horror of Halloran House?"
(A few caveats: There are no stats given for the antagonists in this scenario, but you should be able to pull everything you need from the CoC rulebook - I did! Also, I had to pull the floorplans of Halloran House from the document, since they were modified versions of something I took from one of Chaosium's supplements.)
