The old Victorian house stood silent beneath moonlight’s pale glow. Rain tapped softly against the windows, echoing through empty halls. A single candle flickered on the mahogany side table’s edge. The air smelled of damp wood and something faintly metallic. Footsteps crunched gravel outside, though no one had arrived. The front door creaked open, revealing a shadowed figure’s silhouette. A letter lay crumpled on the floor near the dead man’s hand. His eyes were wide, frozen in an expression of sheer terror. The clock struck midnight, its chime echoing through the stillness. Something cold pressed against my wrist, pulling me toward the scene.
