The rain drummed against the windows as shadows stretched long across the dimly lit parlor. A single candle flickered weakly, casting eerie light on the faces of guests gathered in tense silence. Eleanor’s sharp laugh echoed through the room, startling the nervous attendees gathered there tonight. Each guest held a drink, their eyes darting toward the door, sensing something amiss in this strange gathering. The air smelled faintly of old books and something metallic, hinting at secrets buried deep within these walls. A clock ticked loudly, its hands moving slowly, as if time itself had paused to witness this gathering’s dark purpose. The host, an enigmatic figure in a tailored suit, stood near the fireplace, his voice dripping with calculated charm. His words were laced with promises of wealth and power, but beneath them lay a hidden, deadly threat. Eleanor’s smile never wavered, though her fingers tightened around her glass, her pulse racing with hidden dread. The guests whispered among themselves, their conversations growing increasingly hushed and suspicious. A sudden knock at the door sent a chill down everyone’s spine, making them all turn toward the sound. The host’s smile widened, revealing teeth too white, as he stepped forward to answer the mysterious visitor’s call.
