The grand ballroom glittered under crystal chandeliers this cold evening. Lady Pemberton's annual charity gala attracted the city's most elite. Distinguished guests sipped champagne while discussing art and recent scandals. Detective Morrison noticed tension crackling between several prominent wealthy families. Lord Ashworth argued quietly with his estranged business partner near. The orchestra played softly as couples danced across polished floors. Suddenly, piercing screams echoed from the mansion's dimly lit library. Lady Pemberton lay motionless beside her overturned mahogany writing desk. A silver letter opener protruded from her silk evening gown. The detective knew this elegant party had become a crime.
