D&D: Curse of Strahd Pidlwick II

Pidlwick II was kept in a small closet adjacent to one of the guest bedrooms. On the rare occasion when someone stayed there, Pidlwick would sneak out of the closet in the middle of the night, smother the guest with a pillow, and then retreat back to the closet. The castle staff never considered that the effigy might be responsible, instead assuming that the guests had died in their sleep.
