The moon casts eerie shadows across the grand estate’s crumbling gardens at midnight. A single candle flickers weakly, casting long, trembling beams on the polished marble floor. Whispers echo through the empty halls, though no one dares to step forward or speak aloud. The butler’s stiff fingers clutch his teacup, his knuckles white as he watches the door swing shut. A faint, metallic clink echoes from upstairs, sending a chill down the spine of every guest present. The air grows thick with tension, as if the very walls are holding their breath in anticipation. Each guest’s eyes dart around, searching for any sign of danger or hidden danger lurking nearby. The last guest enters, her breath visible in the cold night air as she adjusts her gloves. A shadow moves swiftly past the window, leaving no trace behind but a lingering sense of dread. The clock strikes twelve, marking the moment when secrets buried deep inside this house will be revealed. The guests stand frozen, their hearts pounding as they realize they are all trapped within this deadly game.
