“There was a grumpy librarian in the library. I could tell that he was the librarian because he seemed to be made of books. I told him that we needed information, and he got us some butterfly nets and sent us up to the top floor of the library. I wondered why we were carrying nets. Valentine didn't know. The book I wanted was pretty obvious. It was called A History of Everything. Finding it was easy. Catching it, however, was not. The moment I reached for it, the whole shelfful of books took off into the air, fluttering like pigeons, and suddenly I knew what the butterfly nets were for. I waved the net about and eventually I caught A History of Everything. As soon as I'd got it, all the rest of the books flapped back to their shelf, all except one, a little red-covered book, which fluttered over my head happily.”
