The setting of Highgate Cemetery in the 70s is a fascinating choice, a very spooky setting for an atmospheric and well realised vision. Given it’s her last story it’s, quite rightly, the Clara show - she gets to be the person who the plot hinges off of. I will miss her.

I enjoyed all the character interactions, including the distinct lead guest characters (paranormal activist vs. cult leader) both of which are very well drawn.

It is let down by a surprisingly flimsy resolution which does not live up to the rest of the story.
