This is the penultimate episode in the Missy box set, and like the previous two it has a wickedly dark sense of humour. I chuckled a lot at the narrative's satirical take on crime documentaries, and Missy's takedown of some of this genre's clichés is hilarious to witness. It's all rounded off nicely with the reveal concerning the Master's Grandfather Clock TARDIS, which provides a neat callback to Classic Who.
