Heavy rain lashed relentlessly against the tall dark library windows. Lord Harrington lay motionless upon the Persian rug in blood. A sharp silver letter opener protruded from his cold chest. The grandfather clock chimed midnight across the silent eerie room. Detective Miller carefully stepped inside and examined the gruesome scene. An unfinished glass of expensive scotch sat near the body. Fresh muddy footprints led directly toward the open balcony door. Someone in this grand house was clearly a ruthless killer. Miller put on his leather gloves to begin his investigation.
