The clock struck midnight as shadows stretched long across the grand ballroom. Glowing chandeliers cast eerie light on guests in their finest evening attire. A whispered conversation halted abruptly when a single gunshot echoed through the air. Silence fell heavy, broken only by the distant sound of a woman’s wailing. Someone had been shot dead in the middle of this lavish, glittering celebration. The butler stood frozen, clutching his side, as the crowd began to scatter. A bloodstained handkerchief lay near the body, its edges damp with crimson. The victim’s last words were barely audible, lost in the chaos of the event. A single key was found near the corpse, its lock unlatched and rusted. The killer’s identity hid beneath layers of deceit and carefully planned deceit. Every guest had motive, but none could explain why they’d chosen this night.
