The old Victorian house stood silent beneath moonlight’s cold, pale glow. Rain tapped rhythmically against the peeling paint on weathered wooden siding. A single candle flickered weakly, casting long shadows across the dusty floor. The front door creaked open, revealing a figure wrapped in a dark coat. Footsteps echoed hollowly through the empty, drafty hallway stretching ahead. Whispers drifted from the upstairs room where no one dared to go. A key turned slowly in the lock, its metallic click sharp in the silence. The intruder’s breath came ragged as they stepped into the dimly lit parlor. A figure lay motionless on the velvet sofa, one hand still clutching a knife. The killer’s reflection flickered wildly in the mirror’s cracked, warped surface. Blood pooled silently beneath the victim’s outstretched, lifeless fingers. The clock’s hands moved forward, each tick a slow, unfeeling judgment. Outside, the wind howled like a voice demanding answers no one could give.
