It's not the same book, but two different people see it in different ways. One person sees it as a circle that's swallowed people, while the other sees the book as a book of witchy diagrams. The two of them draw a circle around the book and draw an apple over it. They're not sure what's going on, but they're pretty sure that it's a witch's book. They draw another circle around it and draw another apple over the top of it. It looks like someone's been messing around in the library. The librarian is the one who messed it up, and he's the only one who can see the contents of the book. He's supposed to be able to see everything, but he can't, because the book is so weird. He tells the librarian to take care of himself, because if he catches him again, he'll make sure that he gets punished.
