Model response

Rain lashed the mansion's darkened, gothic-style windowpanes.  A single candle flickered, casting dancing shadows across the room.  Lord Ashworth lay sprawled, strangely still upon the Persian rug.  His normally stern face wore a look of abject surprise.  A single crimson stain bloomed on his crisp white shirt.  Detective Harding surveyed the scene with a keen, observant eye.  The heavy oak door stood ajar, inviting the cold night.  No obvious signs of forced entry were immediately apparent.  A faint, cloying scent of almonds hung in the air.  Someone had surely silenced this man this very night.
