Rain polished Blackwood Manor's windows. At midnight, Clara heard glass. Downstairs, the grandfather clock stopped. Someone whispered behind the library. Clara descended, gripping her candle. Lord Blackwood sprawled beside roses. Blood darkened his dinner jacket. His locked safe stood open. The emerald necklace had vanished. Six guests watched Clara enter. None appeared shocked or frightened. Then Blackwood's corpse softly laughed.
