The antique manor creaked as twilight slipped through stained glass windows, casting eerie shadows across the marble floor softly late. Inside, the dining hall was dim, illuminated only by a flickering candle perched precariously atop the grandfather clock silently. The butler, a stern man named Reginald, clutched a silver spoon, his eyes darting nervously through the hallway and silently. At the center, a portrait of the late patriarch stared back, its eyes seeming to follow every movement in silence. Suddenly, a blood-curdling scream echoed, and the lights flickered, plunging the manor into deep darkness for one saw anywhere.
