Rain fell hard on Millbrook. The old mansion loomed silently. Blood stained the marble floor. Nobody heard the fatal scream. A candle flickered near midnight. The butler discovered the body. His eyes stared into nothing. Detective Hayes arrived within minutes. She lit a single cigarette. Something felt deeply, terribly wrong.
