Rain hammered Blackthorn Manor's windows. Midnight silenced the gathered heirs. Lady Voss raised trembling champagne. Then lights died without warning. A scream split the darkness. Matches flared beside marble stairs. Lord Voss lay horribly still. Blood darkened his silver waistcoat. Detective Mara Vale noticed footprints. They led toward locked doors. Every heir denied leaving dinner. The grandfather clock began laughing.
