Preamble: This week's story, Gitchy Manitou's Bang, is such a peculiar specimen that I'd rather save my preamble for past the post. That is to say instead of saying things about the story up front I'm going to tuck them in back behind.
After the end of the story when everything goes all italicky again you'll know the fiction is over and the post-post preamble has begun. Or resumed. Whatever. Clear?
(The words of the story are arranged sequentially beneath the fold.)
