At midnight, the manor clock stopped before the final chime. Inspector Vale found the study locked, its window wide open. Lord Ashcombe lay beside a cold, untouched cup of tea. Rain tapped the glass, though no footprints crossed the gardens. On the desk, someone had written Vale’s name in red. His partner whispered, “That message definitely wasn’t there yesterday evening.” Vale smiled, then noticed the ink still glistening beneath lamplight. Someone inside the house had watched him arrive alone tonight.
