Dr. Percivale stands and shakes his head. Of course they would think the house was haunted, simple folk always try to simlify the supernatural. "Haunted" indeed. Either they're rationalizing what should be perfectly obvious, or taking it to the opposite extreme and stirring up ghastly folk lore over what is perfectly rational.
At any rate, if there is nothing more to be said, he will help himself back down to the coat closet and get his things (unless a servant does that for him).
