Rain battered Blackthorn Manor's windows. Guests gathered beneath trembling chandeliers. Colonel Vale arrived precisely midnight. His gloves dripped crimson water. Nobody noticed his missing shadow. Dinner bells rang through darkness. Lady Harrow served poisoned champagne. Then the lights abruptly vanished. A scream shattered every conversation. When candles returned, Vale smiled. A knife bloomed from him. Blood stained the silver centerpiece. Everyone watched nobody move anywhere. Detective Finch counted thirteen footsteps.
