Model response

Rain fell on Darkwood Manor. The clock struck midnight slowly. Nobody heard the sharp scream. Blood stained the marble floor. Lord Hargrove lay perfectly still. His eyes were wide open. A candle flickered and died. The guests sat in silence. Someone among them was guilty. Detective Crane stepped through smoke. She knelt beside the body. A dagger was still missing. The killer had been careful. But not careful enough tonight.
