Model response

Rain polished the courthouse windows.  
Inspector Vale arrived without knocking.  
Inside, midnight smelled faintly floral.  
A body waited beneath chandeliers.  
Someone had arranged its hands.  
Both palms faced the ceiling.  
Vale noticed crimson beneath nails.  
Then the dead man blinked.  
Vale drew his revolver immediately.  
The witnesses screamed from upstairs.  
No witnesses had entered yet.  
Footprints crossed the dusty carpet.  
They ended beside Vale’s shoes.  
Behind him, the door locked.  
The corpse whispered Vale’s name.
