Rain worried the mansion windows. Inside, dinner cooled beside silence. Lady Harrow lay beneath candles. Her pearls drank the moonlight. No one touched their soup. Somewhere, a clock swallowed midnight. Then the butler screamed upstairs. Footsteps gathered like guilty birds. Detective Vale removed wet gloves. He smelled roses and cordite. Everyone else smelled only fear.
