Model response

Rain stitched silver seams across the manor's blackened windows tonight.  
Inside, candles shivered, casting accusations over portraits and polished floors.  
Detective Mara Holt entered last, carrying a notebook and dread.  
The butler stood rigid beside the hearth, hands trembling visibly.  
At midnight, the widow screamed; Lord Vale lay dead upstairs.  
No one had seen the staircase, though everyone heard footsteps.  
Mara noticed mud on the carpet, fresh and leading inward.  
Somewhere in the house, a clock stopped, then someone laughed.
