Model response

Lightning flashed across the sky above the isolated country mansion.  
Inside, the wealthy host entertained his suspicious group of friends.  
Laughter echoed from the parlor until a scream pierced the air.  
Guests rushed toward the study where the door stood ajar.  
There lay the host, lifeless, with a knife in his chest.  
Blood pooled on the Persian rug beneath his cold body.  
Who among them had plunged the blade into his heart?  
The detective arrived soon after to unravel the deadly mystery.
