What happened later that morning?

Later that morning,the landlord and his wife found the door of the scientist's room wide open.They couldn't miss the opportunity of investigating his room. They found that the bedclothes were cold, which showed that the scientist had already woken up. In addition to that, the clothes and bandages that he always wore were lying about the room. While Mrs hall was searching the room, she heard a sniff close to her ear. A moment later the hat on the bedpost leapt up and dashed itself into her face. Then the bedroom chair sprung into the air and charged straight at her legs foremost. Pushing them both out of the room, it slammed and locked the door after them.
