Model response

Rain lashed the old manor windows.  
Lightning cracked the midnight sky open.  
Guests mingled in the smoky parlor.  
Laughter masked the growing tension inside.  
A scream pierced the festive clamor.  
They rushed toward the library door.  
Lord Blackwood lay dead on carpet.  
Blood stained the antique Persian rug.  
Knife protruded from his lifeless chest.  
Inspector Hale surveyed the gruesome scene.
