Model response

Rain slicked cobblestones as Detective Mara arrived at Alder House.  
A butler whispered, saying the master never woke from dinner.  
Inside, candles burned though morning still blurred through curtains quietly.  
The study smelled of lilacs, and a revolver lay nearby.  
On the desk, a torn letter displayed unfamiliar handwriting alone.  
Mara examined footprints, noting only one pair entered, leaving freshly.  
She asked who served port, and everyone suddenly looked guilty.
