The grandfather clock struck twelve, but no one heard it above the storm’s roar. Rain lashed the manor’s windows like a thousand tiny, frantic fists. Inside, ten guests feasted beneath a chandelier’s trembling, crystalline light. Lord Ashford laughed, his brandy glass raised in a final toast. A sudden scream shattered the warmth, shattering the room’s brittle peace. He crumpled to the Persian rug, a silver dagger buried in his back.
