The rain hammered rooftop while detective Miller waited downstairs impatiently. She had never seen a corpse sit so perfectly upright. The victim wore tuxedo, untouched wine, and strange quiet smile. Around him, twelve dinner guests whispered, none dared move closer. Someone had poisoned his drink, Miller knew it almost instantly. But the killer remained seated among them, still sipping champagne.
