The storm raged outside as the guests arrived reluctantly tonight. Heavy rain pounded against the manor’s ancient windows relentlessly tonight. Candlelight flickered eerily, casting long shadows across the grand hallway tonight. Whispers floated between nervous guests, their faces barely visible tonight. A sharp scream suddenly cut through the tense atmosphere tonight.
