I can only assume this story's been in a drawer for years, and they dusted it off to fill space. All the characters are ciphers; if not for the art - bad as it is - and expository captions, there'd be no way to tell who's meant to be in this story.
I'm putting McMurray on my list of writers to avoid. She seems to mostly get bit work like this, but the other stories have to work that much harder to make the full package worth buying.
