Sense Sonnet - Chiller

Tourist Trap

I am driving through Salem, Mass.
I stop at a filling station.
I go in to pay for the gas,
Then continue my vacation.
I can see in the rear view mirror,
A painting sits on the back seat.
When in the hell did that appear?
I pull to the side of the street.
It shows the burning of a witch,
With her shadow against a tree.
My God, the shadow starts to twitch,
As though it's trying to break free.

The shadow of the witch has spread.
It's hovering above my head.
