Rain stitched silver threads across the windows of Blackthorn Manor. At midnight, the grandfather clock struck thirteen, then abruptly stopped. Inspector Vale arrived carrying an umbrella and somebody else's invitation. The butler admitted him without asking why his hands trembled. “You're late,” he whispered, glancing toward the locked drawing room. Inside, nine guests sat motionless around a table awaiting dinner. Their host lay beneath it, his white waistcoat soaked crimson. A silver knife protruded neatly between the dead man's ribs. Nobody screamed when Vale knelt beside the body, checking pockets. He found a watch, a key, and his own photograph. On its back, somebody had written tomorrow's date in blood. Behind him, the butler quietly locked the only remaining exit.
