Model response

Rain hammered Blackwater Manor as guests gathered beneath crystal chandeliers.  
At midnight, Lord Vale raised his glass and smiled broadly.  
Then every candle died, leaving the ballroom breathless and blind.  
A pistol cracked upstairs, sharp enough to silence thunder outside.  
When lamps returned, Vale lay sprawled beside the locked library.  
Blood darkened his cuff, while a silver key gleamed nearby.  
Detective Mara Quinn studied the key, then counted thirteen footprints.  
Only twelve guests had entered, and nobody admitted leaving early.
