It's my second time in the library - trying to find the Monster book. I am able to find it at the top left hand corner of the 2nd room in the library. I have placed the table and the movable bookcase at the top left hand corner of the room as well. I tried many positions for the bookcase and the table but I am unable to get Harry to point the wand at the book. Is there a specific position that the table and bookcase have to be in for Harry to point at the Monster book?
