The rain hammered against the narrow windows, casting flickering shadows as Detective Harris entered the dimly lit abandoned mansion swiftly. Footsteps echoed softly on the creaking wooden floorboards, revealing the faint scent of smoke intertwined with lingering fear and despair. A single candle flickered atop a dusty desk, illuminating a blood-stained letter discarded carelessly beside a shattered vase. Outside, the storm raged fiercely, darkness deepening as distant sirens wailed ominously, hinting at chaos hidden within this haunted estate. Inside, silence fell suddenly, broken only by the faint whisper of wind slipping through cracked shutters revealing secrets long buried deep inside.
