Model response

The clock stopped at midnight.  
Rain stitched silver across windows.  
Inspector Vale entered without knocking.  
Lord Ashcombe lay beneath portraits.  
His teacup remained perfectly untouched.  
One gloved hand clutched something.  
Vale knelt, revealing a button.  
Not his, the inspector realized.  
Someone had locked every door.  
Yet mud crossed the carpet.  
Vale followed it toward curtains.  
Behind them, breathing suddenly stopped.  
Then the clock struck twelve.
