Terror Of The Master Part One: A suspenseful introduction to this epic UNIT adventure. This instalment does a great job at exploring the Doctor's sadness following Jo's exit, and we even get an origin story for the Whomobile. This first part also ends in spectacular fashion, with the Doctor and the Master chased by a hit squad, supposedly sent by the Master.

Terror Of The Master Part Two: An excellent second episode, as the story really kicks into gear. It feels like the Master is on the backfoot here, as his latest alien ally turns against him. Also great hearing the moment between the Third Doctor and the Brigadier, after the Doctor is poisoned. Their friendship is easily one of the biggest highlights of the Pertwee era.

The final part acts as a fitting conclusion for Roger Delgado's Master, as he begrudgingly teams up with Jon Pertwee's Doctor. Jon Culshaw's impressions are as ever on point, and his narration is as great as in the other two parts.

Overall, Terror of the Master is definitely a story worth a listen.
