I loved this book! The banter between ten and Martha is really fun, and I thought the author did a great with their characterization. There were a lot of little lines in this book, both between Martha and the Doctor and just in general, that made me smile. The first few chapters I thought it was going to be a fairly paint by numbers mystery that I’d have to sit through just for the sake of watching the Doctor and Martha interact with it, but it started to change and pick up speed. I genuinely found it really fun. This story probably wouldn’t have worked for TV, since a lot of it is just moving around one location, but it’s phenomenal as a book. An overall solid and fun ten and Martha adventure!
