Rain tapped Blackthorn Manor's windows. Guests whispered beneath crystal chandeliers. Silver gleamed on polished tables. A violin trembled from somewhere. Then darkness swallowed every candle. Someone laughed, thin and frightened. When lights returned, Lady Harrow lay motionless beside the roses. Her pearls were scattered widely. A scarlet stain spread silently. No door had even opened. No servant admitted seeing anything. Only the clock kept ticking. Midnight had just finished striking. Inspector Vale removed his gloves. He studied each startled face. One murderer stood among them. And dinner had just begun.
