The clock struck midnight as shadows stretched long across the grand ballroom. A single candle flickered weakly, casting eerie light on the guests gathered tight. Whispers slithered through the crowd, each voice carrying secrets no one should know. A woman’s laughter echoed strangely, too bright against the tension thick in air. The butler stood rigid, his eyes fixed on the door where footsteps had paused. A knife glinted in the dim glow, its edge sharp enough to cut through lies. Someone had been poisoned, but who left behind such a chilling, deliberate trace? The guests turned as one, their gazes darting toward the figure standing alone. A whispered name was spoken, then vanished like smoke in the drafty hall. The air hummed with dread, each breath a warning of what was about to fall. The game had begun, and no one would walk away from this deadly hall.
