What extraordinary things happened at the inn?

Besides the incident of stealing money from the clergyman's desk, many other extraordinary things happened at the inn. One day Mr. and Mrs. Hall saw the scientist's door open. Usually, it remained closed. They entered the room to investigate. They found the clothes cold which showed that the scientist had been up for some time. The bandages and clothes that the scientist wore were lying about the room. Suddenly Mrs. Hall heard a sniff near her ear. At once the hat from the bed leapt up and dashed itself into her face. In the meanwhile, the chair became alive and threw itself out of the room.
