Rain hammered Blackthorn Manor as guests arrived for supper. At midnight, the library clock stopped beside Colonel Ashcombe's corpse. Detective Mara Venn noticed mud beneath the locked window. No one admitted hearing screams during the thunderous storm. Lady Ashcombe calmly poured tea, her gloves still spotless. The butler whispered that everyone hated the colonel deeply.
