Model response

The detective entered the dim room.  
Blood pooled across cold marble.  
Silence hung heavy like fog.  
A single candle flickered weakly.  
Footsteps echoed from distant hall.  
Shadows danced on velvet curtains.  
The victim lay face down.  
His watch had stopped ticking.  
A faint perfume lingered nearby.  
Something felt terribly wrong here.
