The one where Castrovalva folds in on itself...
I really like the idea behind this episode - or rather, behind the idea of Castrovalva as a place - because it plays with time thematically, in keeping with the story as a whole. The Doctor gradually works out that The History of Castrovalva (all 30 volumes of it) consists of books which were bound 500 years ago, but which chronicle the rise of the township up to the present day. Oops! That's a major boob, Master! But I do like the slow realisation that these old books contain new information from after the time they were created, like "time books"! The entire history, and by association the entire existence, of Castrovalva is a fiction!
At first it's considered that Shardovan the librarian has invented the history himself, a further example of writer Christopher H Bidmead trying to distract the viewer by making them think the man in black is the bad guy here. Actually, he's far from the bad guy, he just likes to dress that way.
