Rain battered Blackthorn's iron gates. Inside, twelve guests dined silently. Lightning exposed the vacant chair. Then the butler screamed upstairs. Everyone froze beside crystal glasses. Professor Vale lay dead upstairs. A silver letter opener protruded. Nobody admitted hearing any struggle. Detective Ives locked every door. Outside, rain erased departing footprints. Inside, someone poured another drink.
