Model response

Moonlight pooled on cobblestones outside Harrowgate Manor, silent tonight.  
Detective Eliza Ward arrived, holding her notebook, eyes alert always.  
Inside, servants whispered softly, fearing the upstairs study's secrets.  
The body lay sprawled near the fireplace, perfectly undisturbed.  
A silver clock had stopped, precisely at midnight, strangely.  
Marble dust marked footsteps, yet no windows showed forced entry.  
Lord Harrowgate’s portrait watched, while candles flickered like nerves.  
Eliza examined the victim’s hands, noting unfamiliar garden soil.
