Lightning crashed as the old mansion loomed behind thick fog. Footsteps echoed softly across ancient, creaking wooden ballroom floors. A blood-stained glove lay beside an overturned candelabra nearby. The clock struck midnight, sending shivers down every guest’s spine. Detective Harper entered quietly, his sharp eyes scanning each face. Rain rattled the windowpanes, masking the hush of dread. A pale maid screamed, pointing to the shadows behind curtains. Someone gasped; the butler’s cold body sprawled on plush carpet. The room froze, suspicion weaving quickly between glances and whispered accusations. Detective Harper drew closer, determined to uncover every hidden secret.
