At midnight, Inspector Vale arrived at Blackthorn Hall, where every clock had stopped at eleven minutes past nine precisely. In the library, Lord Blackthorn lay beneath a shattered chandelier, his white gloves folded neatly beside his untouched wineglass. The household insisted they heard no crash, though fresh plaster dust still floated through the warm, strangely fragrant air. Vale noticed a single wet footprint near the hearth, pointing toward a fireplace that had not burned in years. Then the dead man's watch began ticking inside his locked desk, and someone upstairs quietly turned another key twice.
