"A lifeless man, lying outstretched on a certain hearthstone, might be found once in a house and awaken no special comment; but when this same discovery has been made twice, if not thrice, during the history of a single dwelling, one might surely be pardoned a distrust of its seemingly home-like appointments, and discern in its slowly darkening walls the presence of an evil which if left to itself might perish in the natural decay of the place, but which, if met and challenged, might strike again and make another blot on its thrice-crimsoned hearthstone."
