The clock struck midnight as shadows stretched long across the grand ballroom. A single candle flickered weakly, casting eerie light on guests’ faces. Whispers filled the air, though no one dared speak aloud tonight. A woman’s voice trembled as she clutched her glass, her eyes wide with dread. The orchestra played a haunting melody, too soft to mask the tension. A man slipped away unnoticed, his coat blending with the dark. A single footstep echoed softly, then silence returned to the room. The air grew thick with secrets, each guest hiding their true intent. A hidden door creaked open, revealing a narrow staircase below. The last guest vanished without a sound, leaving only silence behind.
