The rain pattered against the window, casting shadows long and dark upon the crumbling mansion’s walls. A single candle flickered weakly, casting eerie light on the dusty floor where footprints led nowhere. The clock struck midnight, its chime echoing hollowly through the silent, suffocating air. A shadow moved swiftly past the open door, leaving no trace behind in the dimly lit hallway. Whispers slithered through the cracks, though no one dared to speak aloud in fear of what might hear. The air smelled of decay and something faintly metallic, clinging to the damp stone walls. A single key turned in the lock with a creak that seemed to scream its own secrets. The door swung open, revealing a figure cloaked in black, standing motionless in the moonlight’s pale glow. No one had been seen entering or leaving for days, yet here they stood, unnoticed and unseen. The house held its breath as the figure stepped inside, leaving behind only silence and dread. A faint, unnatural hum filled the air, like a heartbeat too fast to be human’s own. The last thing anyone saw before the lights went out was the figure’s cold, unblinking eyes.
