# The Storm House Rain hammered the old mansion. Lights flickered twice, then died. Twelve guests sat in darkness. Someone screamed from the library. Candles cast shadows on walls. The host lay on the floor. Blood pooled beneath his chest. Nobody moved from their seats. The butler dropped his tray. "The killer is among us." Thunder cracked outside the windows. The detective stood up slowly. She counted the guests twice. One person was clearly missing. The clock struck midnight loudly. Nobody dared speak a word. The doors were locked tight. Someone had planned this carefully. The storm trapped them inside. Death had come to dinner.
