Thunder crashed as the old mansion loomed atop the hill. Detective Harris arrived precisely at midnight, boots crunching on gravel. Candles flickered in the parlor, casting uneasy shadows on faces. A scream erupted from upstairs, splitting the thick, anxious silence. Guests gathered swiftly, eyes wild, trembling with fear and suspicion. On the grand staircase, a crimson stain bloomed beneath footsteps. The butler stammered, pointing shakily at the closed bedroom door. No one dared move until Detective Harris finally approached cautiously. Her hand hovered over the brass knob, breath caught tight. Behind the door, someone wept softly in the oppressive dark.
