Heavy rain battered the tall windows of Blackwood Manor tonight. Lord Arthur lay motionless upon the expensive Persian library rug. Dark crimson blood slowly pooled beneath his silver silk vest. One antique brass candlestick rested very close to his hand. Detective Clara Vance stepped carefully inside the cold, quiet room. She noticed the heavy oak door had been locked tight. Nobody had heard a single scream during the entire evening. Every dinner guest downstairs held a motive for this crime. Clara knelt down and spotted a torn green velvet ribbon. The killer was definitely still hiding somewhere inside this house.
