At midnight, the chapel bell rang beneath a moonless sky. Inspector Vale arrived before the trembling servants found their courage. Inside, Lord Harrow lay smiling beside the cold stone altar. A silver key protruded strangely from his pale, bloodless throat. No wound appeared, though crimson stained his white evening gloves. The locked doors remained bolted, watched by two frightened footmen. On dusty tiles, wet footprints ended beneath Harrow’s motionless body. Then the dead man’s pocket watch began ticking backwards softly. Vale listened, while thunder whispered across the dark, empty moor. Someone upstairs laughed once, then carefully locked another door nearby.
