Model response

The mansion stood in darkness. Rain hammered against the windows. Detective Cole crossed the threshold. A body lay face down. Blood pooled on cold marble. The victim wore expensive clothes. No one heard the scream. Candles flickered in the hallway. Someone had killed Lord Ashworth. Cole knelt beside the corpse. A knife wound seemed fatal. The butler stood nearby trembling. Every guest became a suspect. This night would be long. Death had visited Ashworth Manor.
