The “prequel” to this weekend’s season finale of Doctor Who.
Of course “prequel” is the wrong word as really a prequel is something that is released after the event that tells the pre-story. This is more of an introduction, but say prequel and people have an understanding of what you mean.
Will be interesting to see how and where the story goes. Of course we know in one way as a Christmas special has been announced!
Spoilers….
