The grand ballroom sparkled with crystal chandeliers and elegant guests. Lady Pemberton adjusted her emerald necklace before greeting arriving visitors. Distinguished citizens from across the county filled the ornate hall. Orchestra music drifted through conversations about politics and recent scandals. Lord Ashworth stood near the fireplace, discussing business with associates. His wife Margaret mingled gracefully among the wealthy social elite. The evening promised to be another successful charity fundraising event. Thunder rumbled outside as rain began pelting the mansion windows. A sudden scream pierced through the cheerful chatter and music. Lady Pemberton's body lay crumpled beside the marble grand staircase. Blood pooled beneath her head on the polished marble floor. Her emerald necklace had vanished, leaving only a broken clasp. The guests gathered around, whispering in shock and growing fear. Inspector Davies arrived within the hour to begin his investigation.
