Underthe gloomy sky, the grand mansion loomed ominously as the guests arrived one by one on that fateful night. One guest stood out, a woman in black who had arrived late and carried a mysterious aura like a shroud. The butler’s nervous glance toward the study hinted that something was terribly amiss behind closed doors on such a night. Meanwhile, in the lavish drawing room, guests whispered nervously while sipping some drinks from the crystal glasses decorated with gold. The host, a wealthy man known for his generosity, had vanished since the final guest had arrived two hours earlier. The grandfather clock in the hallway struck midnight, its deep toll echoing through the silent mansion like a death knell. Suddenly, a blood-curdling scream pierced the oppressive silence, freezing all conversation in the drawing room in an instant of dread.
