The storm raged outside Blackwood Manor, its thunderous growls echoing through the ancient halls like a warning. Rain lashed violently against the stained-glass windows, casting eerie red and blue hues across the grand foyer’s marble floor. A single candelabra flickered in the draft, its dim light illuminating the shadowy portraits lining the walls. A faint scent of aged wood and something metallic lingered in the air, unsettling the guests already gathered. The butler, impeccably dressed, stood frozen near the oak door, his knuckles white around a silver tray. Murmurs of unease rippled through the company as whispers of a figure seen in the west wing spread. The grandfather clock struck midnight, its chime resonating with an ominous finality no one could ignore.
