The rain fell relentlessly over Blackwood Manor that October evening, washing away secrets that had remained buried for thirty years. Detective Sarah Chen stepped from her car, adjusting her coat against the wind while studying the mansion's cold dark windows. Inside the library, Lord Ashworth lay slumped beside the cold stone fireplace, a silver letter opener protruding from his chest. His wife Eleanor stood trembling near the window, her silk gown stained with dark blood that was not her own. The butler had discovered the body at precisely eleven o'clock, when he brought the traditional brandy that his master requested. Sarah noticed the shattered clock on the marble mantel, its hands frozen forever at a moment that seemed strangely significant. Someone had scrawled a single word upon the polished desk in red ink, though the strange message made no sense. The single word was "confession," written in a very shaky hand that clearly suggested the killer had been interrupted somehow. Outside, thunder rumbled across the moors as Sarah pulled slowly on her gloves and carefully prepared to question every guest. Six people waited nervously in the drawing room below, and she knew one of them was definitely hiding something terrible.
