Rain polished Blackthorn Manor’s windows. At midnight, someone screamed upstairs. Inspector Vale entered without knocking. The grandfather clock had stopped. Lady Harrow lay beneath it. Blood darkened her silver gown. A chess piece touched her. It was the white queen. Seven guests watched from shadows. Each claimed hearing nothing unusual. Vale noticed eight muddy footprints. Only seven approached the body. One continued toward the stairs. Upstairs, someone started laughing softly.
