Model response

Rain polished the alley like black glass under lamplight tonight.  
Detective Mara Venn found the body beside a shuttered florist.  
The victim's smile looked peaceful, which somehow terrified her most.  
No blood stained the cobblestones, only a single white lily.  
Mara crouched, noticing the flower's stem was recently cut cleanly.  
Above her, windows yawned darkly, withholding every useful secret tonight.  
Then she saw the note pinned beneath the victim's wrist.  
It read, "Ask the bell tower," and someone laughed nearby.
