As soon as she emerged into the room, she realized that the structure down which she had been descending was neither a well nor a tower, but an enormous chimney whose upper portion had been removed and on whose hearth she had been standing. She brushed her clothes down as well as she could. She was in a small, low-ceiling’d room whose walls seemed to have been whitewashed fairly recently.
