I have to wonder how long ago the story, or maybe just its intro, was recorded. Ann says, "It's read for us by Elizabeth Green Musselman, who hosts a monthly podcast on the history of science, medicine and technology, called 'The Missing Link'..."
I thought to myself,
that sounds pretty cool, I should check that out! Happily, as they always say, 'links in this intro can be found on our web page,' so I checked out the (happily) not missing 'Missing Link' link.

Imagine my disappointment when I discovered that the podcast is on indefinite hiatus and has been since October, due to the amount of time Musselman put into the production and her unwillingness to let its quality suffer. (This speaks well of her commitment to quality in the podcast, and I have no complaint with her decision to put her 'cast on hiatus, even if there are only 14 episodes. That's 14 more than I knew about before.)
What surprises me is Ann referring to The Missing Link in the present tense.
Anyway, that being said, I don't want to be just a complainer so I should mention that I quite liked Musselman's reading; she's now up there among my favourite readers on PC, along with M. K. Hobson.
I'm always a little surprised when I come to this forum and read people's complaints about how the story held no 'deep inner meaning' for them, or had no 'purpose' revealed at the end. I mostly just enjoy the stories for themselves without looking for further meaning than just a decent, and decently told, tale. I guess I haven't had enough indoctrination in English classes...
