The grand old mansion stood tall against the stormy night sky as thunder echoed loudly through the empty dark halls. Footsteps approached the large wooden door where a mysterious figure waited silently in the deep dark shadows of the night. A chilling scream suddenly broke the eerie silence revealing the terrible crime that had just been committed inside the room.
