Model response

Rain slicked the city street.
A body lay still there.
Blood bloomed on the cold ground.
Detective Miles approached the scene slowly.
His breath made a pale cloud.
A chill wind bit his face.
Sergeant Miller stood by the corpse.
“It’s a nasty one, sir.”
The victim wore a fine suit.
His eyes stared at the sky.
A single ornate pen lay.
It was clutched in his hand.
Miles knelt, examining the object.
This was more than robbery.
This was a clear message.
