The grand estate loomed under storm clouds, shadows stretching long. Rain tapped against the windows while guests whispered nervously inside. A single candle flickered as the power suddenly died. Footsteps echoed down the hall before stopping abruptly near study. The butler’s hand trembled while holding a silver tray. Blood dripped slowly from the doorknob onto polished mahogany floors. Someone gasped, then screamed—her voice shattered the heavy silence. Detective Mercer adjusted his coat, eyes scanning every suspicious face. The body lay sprawled beside the fireplace, one hand outstretched. A broken pocket watch ticked its final seconds on cold marble.
