This is adorable:
"Sir Walter started to remove a pile of books from a chair.
"No, no!" cried Strange, "Do not move those! They are in a very particular order."
"But where shall I sit?" asked Sir Walter in some perplexity.
Strange made a small sound of exasperation as if this were a most unreasonable request. Nevertheless he moved the books and only once became distracted in the process and fell to reading one of them. As soon as he had read through the passage twice and made a note of it upon the wallpaper he was able to attend to his guests again."
