Rain hammered Blackthorn Manor as midnight swallowed the surrounding hills. Inside, thirteen guests waited beneath portraits turned toward the wall. Their host had promised revelations before serving the final course. Instead, his chair stood empty, his wine dark and untouched. Detective Mara Voss noticed the silence before anyone mentioned it. Even the grandfather clock seemed reluctant to announce the hour. Then a scream rose sharply from somewhere beneath their feet. The housekeeper appeared, clutching a brass key against her throat. She pointed downstairs, where candlelight trembled along the cellar steps. Mara descended first, counting muddy footprints crossing the polished stone. Lord Blackthorn lay beside his safe, smiling through bloody teeth. In his hand, a photograph showed Mara entering this house. On its back, someone had written her daughter's home address.
