Model response

Rain slicked the manor steps as Inspector Vale arrived alone.  
Inside, candles trembled, and every portrait seemed to watch.  
The host lay dead beneath the chandelier, face perfectly calm.  
No blood marred the carpet, only a silver key.  
Guests whispered behind fans, alibis fraying in the smoky air.  
Vale noted thirteen clocks, each marking a different time.  
Then someone screamed upstairs, and footsteps vanished into silence.
