Model response

Fog cloaked the manor house on the stormy hilltop tonight.  
A piercing scream shattered the silence from an upstairs window.  
Constable Hale sprinted up the gravel path with lantern raised.  
The heavy oak door stood slightly ajar in darkness.  
He pushed it open and called out her name.  
Silence answered as he climbed the creaking wooden staircase.  
Upstairs, Lady Eleanor sprawled lifeless on her silk-sheeted bed.  
Blood pooled around her from a single fatal stab.  
The jeweled dagger lay nearby with fingerprints still fresh.  
Who entered her room to end her life tonight?
