The rain pattered against the windows as shadows stretched long across the dimly lit parlor. A single candle flickered weakly, casting eerie shadows on the antique furniture. A handwritten note lay on the table, its ink smudged with what appeared to be blood. The air smelled faintly of lavender and something metallic, clinging to the room’s stale scent. Each guest arrived with secrets, whispers, and a hunger for the truth that no one dared to voice. The clock ticked loudly, marking the final hour before the killer would strike with precision. A nervous footstep echoed softly through the hallway, followed by a whispered, "I’m not late." The butler adjusted his tie, his expression unreadable, as he watched the guests gather inside. A sudden gust of wind rattled the glass doors, as if nature itself was conspiring to hide the truth. A single tear slipped down the host’s cheek, but she wiped it away before anyone noticed her pain. The guests exchanged glances, each one wondering who among them held the deadly secret. A faint laugh escaped one guest, but it sounded hollow, as if they knew something they weren’t meant to say. The host’s voice trembled slightly as she announced, "Tonight, we play a game—one wrong move could mean death."
