The grand ballroom shimmered with a thousand tiny lights. Whispers of champagne and laughter filled the air. Suddenly, the music stopped with a jarring, sharp chord. Emerald eyes stared at the fallen maestro on the stage. A crimson stain bloomed on his immaculate white shirt there. Gasping, guests edged away from the shocking, still scene. The velvet rope lay discarded, just a broken, loose strand. Fear replaced the joyful music, spreading like cold fire. Someone screamed, a high, piercing, terrible sound then. This opulent party immediately transformed into a nightmare.
