Rain battered Blackthorn Manor's windows. Guests whispered beneath crystal chandeliers. Lady Vale raised her champagne. Then darkness swallowed the ballroom. A pistol cracked near midnight. Someone screamed behind velvet curtains. Lights returned, revealing Lord Harrow. He lay bleeding beside roses. His watch had stopped precisely. Detective Morrow entered through thunder. Nobody moved from their places. Everybody claimed they heard nothing.
