Model response

Detective Mara Quinn found bodies at dawn.  
Rain hissed, cloaking the manor courtyard.  
Inside, candles flickered beside shattered mirrors.  
The victim lay still, eyes closed.  
Guests gathered silently, watching Mara carefully.  
Constable Holt noted muddy bootprints leading.  
A silver locket sat near.  
The butler swore he heard nothing.  
Mara questioned everyone beneath drifting mist.  
From upstairs, a scream suddenly echoed.
