Underthe veil of night and torrential rain the grand mansion stood like a fortress shrouded in mystery and uncertainty. The aged butler stood at the grand oak door welcoming each guest with a forced smile upon his weary face. Inside the grand, ornately decorated hall heavy opulent chandeliers flickered casting shadows which danced ominously across the plush velvet walls. A sudden bloodcurdling scream pierced the tense atmosphere making guests freeze in fear momentarily as shadows seemed to whisper warnings.
