The old manor stood dark. Rain lashed against windows. Inside, silence felt heavy. A sudden crash broke peace. Then a bloodcurdling scream rose. Footsteps pounded down the hall. "He's dead!" someone shrieked loud. Lord Harrington lay on ground. His eyes stared at ceiling. A crimson stain spread wide. Detective Eleanor Vance arrived then. She surveyed the gruesome sight. A chilling puzzle awaited her. The killer remained unknown still. Who ended his life here?
