Model response

Rain drummed softly as Detective Hale entered the silent townhouse.  
A single lamp glowed, illuminating scattered keys and broken glass.  
Inside, Dr. Mercer knelt beside the victim, whispering prayers quietly.  
Hale noted blood patterns, then glanced at the clock nearby.  
The wall clock stopped precisely at midnight, no second hand.  
Neighbors gathered behind curtains, trading rumors of vanished heirlooms today.  
Detective Hale requested everyone speak, starting with the butler first.  
The butler smiled nervously, yet his gloves smelled of bleach.
