This week brings a horror story suggested by Stephen King himself.

Not directly, I hasten to add. I never met the man and would probably be too gobsmacked to say anything if I did. The story comes from a writing prompt in his book “On Writing,” a must-have for any writer that fits very neatly on the shelf next to Strunk and White and the most recent Writer’s Marketplace.

The prompt is a little dated, so the story is a little dated; I doubt I wouldn’t have made the antagonist quite so cartoonishly evil if I’d written it today. The Internet being what it is, there’s always the possibility of unintended interpretations. That’s the gamble you take.

Ask Stephen King.
