What other extraordinary things happen at the inn?

Explanation

The landlord and his wife surprised to see the scientist’s door open. Usually it is shut and locked and he becomes furious if anyone enters his room. The opportunity seems too good to be missed. They peep round the door, see nobody and decide to investigate. The bedclothes were cold, showing that the scientist must have been up for some time. All of a sudden Mrs. Hall heard a sniff close to her ear. A moment later the hat on the bed post leapt up and dashed itself into her face. Then the bedroom chair became alive. Springing into the air it charged straight at her, legs foremost. As she and her husband turned away in terror, the extraordinary chair pushed them both out of the room and then appeared to slam and lock the door after them. Mrs. Hall almost fell down the stairs in hysterics. She was convinced that the room was haunted by sprits and the stranger had somehow caused these to enter into the furniture.
