This 1968 / 2018 epic is one of my favourites. The idea behind Salamander may be a blindingly obvious one, the ruthless, powerful megalomaniac who happens to have the exact appearance of our main protagonist, but they really pull this off. They evil high concept villainous plan has a logic to it and an epic sense of scale which we haven't seen since the dreadful The Dalek's Master Plan.

The volcano, blackmail and poison scenes, all in quick succession do a great job of showing off Salamander's evil credentials. I love the idea of someone controlling the world through manipulating weather and natural disasters. Jamie works so well as a character in this scenario, infiltrating the compound by "saving" Salamander's life. He is one of the best character's the show has ever seen.

The secret bunker has to be my favourite element of this story. The radiation suit and secret life is genuinely exciting, you wonder where Salamander could be off to. The fact he has a bunch of scientists locked up through trickery, unwittingly doing his evil dirty work - this is the factor that makes this story genius. You really feel for this band of "survivors" that believe a previous war has left the earth above radiated and ruined.

When the newspaper clipping is found by one of the underground scientists Salamander's lies begin to unravel. Salamander tries to do away with him, but he is discovered by another one of this story's heroes Astrid (who has a brilliant electric flirty moment with The Doctor in episode one that really has to be seen to be believed). She successfully convinces the underground people of Salamander's deceit which sets the dictator's downfall in motion.

Its great to see Patrick Troughton's two characters finally meet in the TARDIS at the end of the final episode. This is an exciting fight to witness, but it is perhaps the only part of the story which feels rushed, if this had been a little longer then the ending could be a little more satisfying.
