The rain fell like knives. Detective Marsh arrived at midnight. The body lay face down. Blood pooled on cold marble. Nobody heard the fatal shot. A candle flickered then died. Marsh knelt beside the victim. Her pearls were all scattered. The window stood wide open. Curtains danced in wet wind. A glass sat half full. Lipstick marked the crystal rim. Marsh pulled his notebook out. Something felt deeply wrong here. The killer had left quickly. Footprints crossed the white rug. They stopped at the fireplace. Ash still glowed faintly orange. A note had been burned. Only one corner remained intact.
