Rain hammered Blackthorn Manor as guests gathered for dinner. Detective Mara Vale arrived late, carrying an unopened invitation. Inside, candlelight trembled across portraits with watchful, familiar eyes. Lord Blackthorn smiled warmly, though nobody returned his greeting. At midnight, thunder silenced the orchestra beneath the ballroom. Then a scream rose sharply from the locked library upstairs. Guests rushed upward, finding Blackthorn sprawled beside his desk. A silver knife gleamed between scattered letters and broken glass. Mara knelt beside him, noticing mud beneath his fingernails. Outside, the storm erased every footprint leading from manor.
