This was a pretty clean and fun adventure for the First Doctor. I liked the content around Napoleon and the Shape-Shifter. It all feels right in line with the tone of the First Doctor era, perhaps to a fault such that it feels a little average. Still, I had fun listening. I probably wouldn't be eager to revisit any time soon, but Peter Purves is able to carry the story nicely with his narration enough that it was definitely worth listening to at least once (especially because I got this one through the library).
