Model response

Rain fell on silent streets.  
A shadow moved through fog.  
Old mansion loomed in darkness.  
Emma arrived at midnight hour.  
Door creaked open slowly now.  
Inside, guests waited in tension.  
Clock struck twelve loud times.  
Scream echoed from the hall.  
Body lay on cold floor.  
Blood pooled under pale skin.  
Suspects gathered around the scene.  
Whispers filled the heavy air.  
Detective entered with sharp eyes.  
Mystery began in that room.
