The Uncharmed Life

The townsfolk spread rumors about Mercy Polk and her use of magic charms, potions, and wands in unusual rituals.
She was arrested and dragged before the town magistrate, and ordered to demonstrate her supposed magic powers.
She dipped her finger into a bowl of water, and turned it into wine.
“What is that in your other hand?” asked the magistrate.
“A stone!” shouted the bailiff. “The rumors are true! She has no powers whatsoever!”
The magistrate found her guilty and sentenced her to exile in Boston.
(And kept the stone for himself, since good wine is so hard to find.)
