Model response

The moon hung low and heavy over Blackwood Manor, its light slicing through the fog.  
Inside the grand ballroom, guests laughed and danced, unaware of death lurking nearby.  
A sudden scream shattered the music, freezing every soul in a tableau of terror.  
Lord Ashford lay crumpled on the Persian rug, a single red rose upon his chest.  
No one had seen a stranger enter, and no weapon could be found near the body.  
The grandfather clock struck midnight, its chime sounding like a final, mocking farewell to him.
