The church clock struck thirteen. Nobody in Blackthorn noticed immediately. Rain swallowed the final chime. Then someone began to scream. Inspector Vale dropped her cigarette. It hissed against wet cobblestones. Across the square, windows brightened. A woman emerged from shadows. Blood darkened her white gloves. She carried the mayor’s key. His study door stood open. Inside, Mayor Bell lay motionless. A silver knife pinned something. Paper protruded beneath its blade. Vale read the handwritten message. Your sister’s death was deliberate. Vale had buried her yesterday. Behind her, the door clicked. The woman had vanished outside.
