Rain polished Blackthorn Manor’s windows. Inside, twelve guests awaited midnight. Then every candle died together. A pistol cracked upstairs sharply. Silence swallowed the dining room. Detective Mara Vale climbed first. Lord Ashcombe’s door stood locked. Someone whispered, “He deserved this.” Mara broke the silver latch. Ashcombe slumped beside his desk. No weapon marked the carpet. His dead hand gripped rosemary. Behind them, floorboards quietly creaked. One guest had followed Mara. Yet no living figure appeared.
