They finally came to the last living-room of all, and both exclaimed together: "This is the room I like best of all!"

It was an octagon library, lined with mahogany bookcases filled with bound books which looked as though they hadn't been disturbed for fifty years. The wide, fan-shaped window looked out on a formal rose garden.
