Rain battered Blackthorn Manor gates. Twelve guests watched midnight arrive. Then the lights died abruptly. Someone screamed beside the fireplace. Lord Vale lay dead nearby. Blood darkened Vale's white jacket. His locked study stood empty. Detective Mara Quinn checked windows. Every latch remained firmly bolted. Outside, thunder erased departing footsteps. Nobody admitted knowing Vale's murderer.
