You are at the bottom of the cellar ladder when the trapdoor slams shut and you hear a bolt slide across and lock. You hammer on the trapdoor desperately trying to escape, but your captors cover the trapdoor with a heavy oak cask and keep guard in the room above. Four days pass before the lock slides back, but the hands that open the trapdoor are bony and fleshless.
Your life and your mission end here.
