The mansion stood in darkness. Lady Pemberton hosted annual galas. Tonight would be her last. Champagne glasses sparkled like diamonds. Guests arrived in expensive cars. The butler opened heavy doors. Music drifted through marble halls. Everyone wore their finest clothes. Lady Pemberton descended the staircase. Her emerald necklace caught light. "Welcome to Pemberton Manor tonight." Her voice rang with authority. Nobody suspected what would happen. The grandfather clock struck eight. Death would arrive by midnight.
