The one where the Marshal wants to rule New Earth...
Dear oh dear oh dear... this story really does go downhill fast, doesn't it? It didn't start out all that promising, but it enjoyed a bit of a peak midway through thanks to the beautifully lit and directed location filming at Chislehurst Caves. But now we're at the end I can't help feeling that The Mutants really does deserve its reputation as one of the poorest Pertwee serials of all. It's certainly the worst I've watched so far on this marathon, although I'm aware there are horrors to come...
The Investigator (played by Peter Howell with, as per Geoffrey Palmer's Administrator, sacks more gravitas and professionalism than the majority of the cast) arrives with his tribunal and guards in an effort to get to the bottom of this debacle once and for all. Dressed in a rather Time Lord-y fashion, the Investigator listens to the reports and statements of various protagonists in an interminable summary of 'the story so far', like it's some kind of intergalactic Poirot mystery. This tribunal is dull, dull, dull, until the Doctor manages to expose the Marshal's true splenetic nature.
