The rain hammered the old manor's stone façade, casting long shadows across the empty ballroom until midnight's chilling echo still. Inside, the grand chandelier flickered, its crystals rattling like distant thunder over the polished marble floor under the weight of. The host, Sir Reginald Hawthorne, raised his glass, eyes glinting with a secret he could not share until the dawn. A sudden scream pierced the air, and the lights flicked, plunging the hall into darkness as the guests froze silently. When the doors finally opened, a lone figure stood at the threshold, eyes cold as winter's icy breath and silence.
