The candle flickered beside tea. A scream shattered the quiet. Lord Ashworth lay on carpet. Blood pooled beneath his waistcoat. Inspector Hale checked for pulse. No breath came from lips. A single clue caught attention. The window latch was open. Outside thunder rumbled over hills. No footprints marked the ground. This murder seemed utterly impossible. Someone had locked every door. Then why did she feel? A shadow moved behind drapes. The killer was still here.
