I just kinda stumbled into it when I entered... if I recall, it's called "Blood on the Ice", it's a murder mystery thing.
go to the graveyard there, that's where I first remember really starting it... I followed the rumors around town to there if I recall, then did the chain, I think that was what opened up the house.... actually I know it was
Spoiler because the house the murders took place in is the house you end up buying
