At midnight, the clocks inside Blackthorn Manor stopped together silently. Then every window brightened, though no lamp had been lit. Inspector Vale found the front door standing wide open, unlocked. Inside, Lord Ashcombe lay beneath the shattered chandelier, smiling faintly. A silver key rested carefully upon his still, bloodied tongue. No footprints crossed the dust, except Vale’s own muddy tracks. Behind him, someone softly applauded from the darkened staircase above. Vale turned, but only his reflection faced him there alone. The dead man’s eyes followed him across the room silently. Then the clocks began ticking backward, one by one again.
