Model response

Rain worried the mansion windows.  
Inside, candles trembled beside portraits.  
Lord Harrow lay beneath roses.  
His smile seemed recently borrowed.  
Guests circled silently, clutching alibis.  
The clock confessed midnight softly.  
Then someone noticed blood drying.  
Not wine, but murder's signature.  
Detective Vale removed her gloves.  
Nobody breathed when she knelt.  
Outside, thunder rehearsed its verdict.
