Supernatural Fanfic - Dean/Sam..
Sam and Dean investigate a series of murder-suicides in an historic, but crumbling house in a small town in the rural midwest. There's a vengeful spirit in the house, all that's left of a boy who killed his brother before hanging himself in the attic. Sam and Dean get caught up in the same cycle of events that killed eight people over the last decade, and they discover an incestuous affair that led to the boys' deaths. It affects them more than they'd like to admit, raising the question of just why neither of them can ever let the other go.
