Mortimer Stellar, a prolific writer (modeled on somebody who will go nameless but whose initials are Isaac Asimov), is enormously frustrated because an article he written has been bought—but never published. Nor will the publisher let him have it back to publish elsewhere. (This is a frustration, one supposes, that only Asimov or someone like him could truly feel.)
This is a reasonably good Black Widower story, not perhaps the best but not second-rate, either. And, of course, because Asimov himself is, after a fashion, the guest at the banquet, it’s a vaguely interesting poke at himself, too.
