- Go to the Southern side of the room and then look to the West.
- Crouch and head through the short opening in the wall there.
- This will lead you into Monty's Den.
- Continue to the West into the next room of the Den.
- Nothing looks important in here, so go to the North into the hallway that leads to the next room, a bedroom.
