In the House there is a Room. In the Room there is a Wall. This is the Wall of Doors. At the center of the Wall is a fireplace, as tall as a man. The ceiling is lost in the dark, away from the glow of firelight and candlelight, but as high up as the eye can see the Wall is covered in doors and windows and picture frames. Each one is different: large, small, ornate, plain. Through some, snatches of music can be heard. Through others comes the smell of earth or sea air. What are you waiting for? Open one.
