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 butler locked every door. The host’s laughter echoed strangely before falling into dead silence. Blood seeped slowly across the Persian rug’s intricate golden pattern. Someone screamed, but the sound was swallowed by thunder’s roar. Detective Mercer adjusted his gloves, eyes scanning each suspicious face carefully. The victim’s pocket watch lay shattered near the fireplace’s cold ashes. Footsteps faded down the hallway, leaving only questions behind them. Mercer knelt, noticing a monogrammed handkerchief clutched in stiff fingers.
