Throw a book at the chair.
You snatch a book from the bookshelf and heave it at the chair where
the ghost appeared a second ago. It thuds into what must have been the
ghost, and flaps back and forth with pages flying until it bursts into
a large bright flame. The flames flicker around the surface of what
appears to be a tall, beefy human form. In seconds the book is
consumed in flames while you stand in shock, and the old woman
reapears, standing hunched over her cane in front of the chair. She
stares at you angrily, saying nothing and remaining
still.
