Rain battered the ancient mansion under ominous moonlight and thunder. Detective Harris arrived, ghostly silhouette framed by flickering chandelier light. A crimson stain spread ominously across the shattered marble floor. Silence hung thickly; only soft sobs betrayed hidden morbid secrets. Inspector’s gloved hand hovered above the lifeless victim’s cold chest. Lightning flashed violently, illuminating elegant portraits and darkened corridors alike. Footsteps echoed ominously from the grand staircase behind whispered warnings. A single candlestick trembled, spilling wax upon bloodstained oak floor.
