The storm arrived at midnight. Rain hammered the old manor. Inside, candles flickered with dread. Lord Ashworth lay quite dead. His tea had gone cold. Poison stained his purple lips. The study door was locked. Windows sealed from the inside. Nobody could have entered here. Yet somebody clearly had done. Detective Morgan arrived at dawn. She studied the body silently. A torn letter caught light. It named a secret heir. Somewhere, a killer watched her.
