Rain hammered the tarnished windows of Blackwell Manor relentlessly tonight. Detective Mara Quinn arrived precisely at midnight, her coat dripping. The butler, Silas Crane, waited silently beside the grand entrance. Inside, Lord Alistair lay sprawled across his bloody mahogany desk. A single brass candlestick glistened nearby, stained with fresh blood. No footprints marked the dusty floor beyond the body itself. Someone had locked this study from the inside securely tonight. Mara whispered, "The killer never actually left this cursed room."
