Quintus ran in through the closest door and rushed out through that door; the door which is shown in the image. The door opens inward as the hinges and the ring indicates. But the books are lying on the floor in front of the door, which is impossible if the door was opened or closed. The books would have been pushed away from the door. So Quintus felt the librarian had passed the book to the thief and closed the door and then made a mess in the place. or that the librarian himself was the thief.
