Thecandlelight flickered ominously as guests quietly arrived. Murmurs of excitement buzzed through the lavishly decorated room. The host, a wealthy industrialist, greeted each guest warmly. A sudden crash from the study shattered the evening’s tranquility. All heads turned toward the study as frightened whispers filled the air. The host’s valet stood frozen in the doorway, pale-faced and trembling. "Something terrible has happened in the study," he managed to stammer. Guests exchanged nervous glances, their cheerful demeanor suddenly vanished without trace. Within moments, the valet led the group toward the forbidden chamber.
