The storm raged outside as Detective Morrison entered the mansion, her coat dripping onto the Persian rug. Twelve guests sat around the dining table, their faces illuminated by candlelight flickering ominously. "Ladies and gentlemen," she announced, her voice cutting through the tension like a knife. "One among you has committed murder, and I intend to discover who." The butler stepped forward, his hands shaking as he spoke. "Detective, the victim was found in the library just moments before your arrival." Morrison's eyes scanned each face methodically, noting the fear and guilt etched into every expression. "The killer is still here," she continued, "and they will remain until justice demands their confession."
