Model response

Fog shrouded the old mansion on the hill that night.  
Detective Jane Harrow arrived just as rain began to fall.  
She stepped inside, her boots echoing on marble floors.  
The host lay lifeless in the grand dining room.  
Guests gathered around, their faces pale with shock and fear.  
A bloody knife rested beside the victim's cold hand.  
Jane scanned the room for any signs of struggle.  
Suspects whispered among themselves, eyes darting suspiciously around.  
Thunder crashed outside, heightening the tension in the air.  
Who among them held the secret to this crime?
