Model response

Rain veiled Blackwood's eastern windows.  
At midnight, the bell rang.  
Nobody had touched its rope.  
Vale arrived, soaked, silent, alone.  
The room smelled of blood.  
Ashcombe lay beside cold ashes.  
His watch stopped at midnight.  
Vale noticed one detail immediately.  
Outside, rain battered every pane.  
Then the corpse blinked once.
