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.

The Corvids are fantastically scary, and the atmosphere and location lend wonderfully to the horror, completed with fantastic art work. An underwhelming resolution however, left much to be desired.
