"I heard this story from my late friend Shelby Weinberg. Like myself, Shel was a science fiction writer. If his byline doesn’t ring any bells, though, don’t feel ignorant; not many SF fans knew him by that name. Even the pseudonym he used, Hamilton Yale, has become obscure; his novels went out of print years ago, and his short fiction is seldom anthologized any more."
Quasar links out; the story lives on Analog, where the author gets the click.
