At midnight, thunder shook the windows of Blackthorn Manor violently. Inspector Vale arrived before the household discovered Lady Ashcombe’s body. She lay beside the fireplace, clutching a silver chessman tightly. No blood stained her gown, yet her lips gleamed blue. Every clock downstairs had stopped precisely thirteen minutes before midnight. The family watched silently, except young Clara, who smiled faintly. Vale noticed wet footprints leading nowhere across the dusty carpet. Then someone locked the library door from inside the room.
