Model response

Fog cloaked the ancient mansion tonight.  
Guests arrived for the gala.  
Host greeted them with smiles.  
Candlelight flickered in grand hall.  
Dinner served on silver platters.  
Laughter echoed through shadowed rooms.  
Sudden scream pierced the silence.  
Guests froze in stunned horror.  
Host dashed upstairs alone now.  
Door slammed shut behind him.  
Minutes dragged in tense quiet.  
Another cry rent the air.  
They raced up creaking stairs.  
Locked door barred their entry.  
Shoulder smashed wood to splinters.  
Body sprawled on bloodied rug.  
Knife protruded from his back.  
Eyes stared blankly at ceiling.
