Fog pressed against Blackthorn Manor. Guests whispered beneath crystal chandeliers. A clock coughed midnight, then silence. Lady Voss clutched her pearls. The violinist missed every note. Somewhere upstairs, a door screamed. Footsteps stumbled across marble tiles. A candle guttered beside portraits. Then came the dreadful thud. No one breathed for seconds. Butler Graves dropped the decanter. Red wine bled across rugs. Someone laughed, quickly, then stopped. Inspector Hale had not arrived. Yet murder entered right on time.
