Model response

Rain stitched the manor windows shut as midnight gathered itself.  
Inside, the chandelier trembled, though no wind touched the house.  
Inspector Vale arrived late, carrying mud, silence, and dread.  
Mrs. Hallow greeted him, her smile strained like brittle lace.  
The guests clustered in the library, avoiding the locked study.  
Someone had screamed earlier; now only the fire crackled.  
Vale noticed blood beneath the door, dark as spilled ink.  
When he turned the handle, the room held one body.
