Stand so the bookshelves are behind you. Exit the sitting room via the door on the opposite wall that leads into a dining area. Walk to the right of the dining table and towards the front door. Stop just before passing through this door with the hat rack on your left.
Walk out of the sitting area and turn right. Wait just inside the front entrance.
Go through the archway on the right, go to the right side of the black table, cross the room and step near the wooden door with the slats and then stop.
