Candlelight flickered across marble floors. Lord Pemberton held his glass. Champagne bubbled in crystal flutes. Guests laughed beneath the chandelier. The grandfather clock struck twelve. Lady Margaret watched them dance. Servants glided through the crowd. Music drifted through open windows. Suddenly, Pemberton dropped his champagne. His face turned deathly pale. He clutched at his throat. Gasping, he fell to knees. "Someone help him!" shrieked Margaret. Guests rushed to his side. Doctor Greene checked his pulse. The lord was already dead. Margaret's diamonds caught the light. Her smile seemed oddly cold. The champagne glass lay shattered. Pink foam stained the carpet. Inspector Hayes arrived within minutes. He studied the chaotic scene. Something here wasn't quite right. Murder had visited Pemberton Manor.
