Model response

Rain tapped windows as Detective Hale arrived at Graymarsh Manor.  
Inside, candles burned low, illuminating cobwebbed halls and silent servants.  
Master Wycliffe lay sprawled near the library door, unmoving tonight.  
A silver key glinted beside him, still warm from use.  
Hale knelt, noticing no blood, only faint frost patterns there.  
Lady Marianne wept softly, insisting the house stayed locked always.  
Her brother Theo swore he heard nothing through thick walls.  
Somewhere upstairs, a clock chimed thirteen, then abruptly stopped there.
