It seemed in the end that the only thing he could do was to wait and hope that Uncle Andrew and the Witch would come back. If they did, he must rush out and get hold of the Witch and put on his yellow Ring before she had a chance to get into the house. This meant that he must watch the front door like a cat watching a mouse’s hole; he dared not leave his post for a moment. So he went into the dining.room and “glued his face” as they say, to the window. It was a bow.window from which you could see the steps up to the front door and see up and down the street, so that no one could reach the front door without your knowing. “I wonder what Polly‘s doing?” thought Digory.
