Model response

The old mansion loomed against the bruised November sky, its windows like vacant eyes all watching the winding drive below.  
Detective Inspector Kate Marlow stepped from her unmarked car, pulling her trench coat tight against the suddenly biting coastal wind.  
Gravel crunched under her sensible heels as she approached the massive oak door, which stood slightly ajar and unwelcoming.  
A single yellow light flickered in the foyer beyond, casting long, trembling shadows that danced like nervous, silent specters.  
She pushed the door open with a gloved hand, the hinges groaning in protest as if warning her away immediately.  
The air inside was thick with the metallic scent of fresh blood and the sickly sweet perfume of roses.  
A body lay sprawled on the marble floor, a dark pool spreading slowly beneath the perfectly coiffed silver hair.  
Kate's breath caught in her throat as she immediately recognized the emerald brooch pinned to the lifeless chest.
