The fog swallowed Blackthorn Manor. At midnight, the clocks stopped. A scream shattered the silence. Inspector Vale arrived before dawn. Rain polished the gravel drive. Inside, seven guests waited downstairs. None would meet his eyes. The butler led him upstairs. Lord Blackthorn lay facedown, motionless. Blood darkened the Persian rug. His fingers clutched a key. The study had been locked. Its only window was barred. Vale studied the empty hearth. Someone had recently burned papers. One corner escaped the flames. Upon it, his name appeared. He recognized his mother’s handwriting.
