You begin to look for the way to open the hidden door you know is
there. After spending an hour or two searching every nook and cranny
in the room, you begin to loose hope. With a sigh you slump onto one
of the sofas. Suddenly you hear a *click* and a small crack appears in
one of the shelves. Slowly the crack grows and a small door emerges
from the bookcase. You gasp. You don't know how you did it, but you're
glad you did. Opening the door all the way you look into a dark tunnel
filled with cob-webs. Taking a deep breath and a candle, you walk into
the darkness, not knowing exactly where it goes. Silently the hidden
door closes behind you. There is no going back
now.
You look at the bookcase wall and smile.
"If I were making a castle" you muse to yourself "I
would hide a hidden passage behind a floor-to-ceiling bookcase."
