The Mind of Evil

The Mind of Evil is a return to the grittier style of story that was typical of the previous season. The Master is back, planning to start a world war by launching a missile at a global peace conference in London. Meanwhile, he has also developed a machine that removes 'evil' impulses from the minds of criminals, but it turns out that the machine, literally, has a mind of its own.

There are two main threats in this story- the Master's plan to cause global chaos and the Keller Machine. The machine, with the malevolent Mind Parasite inside, is a really frightening concept. Visually, it is a very ordinary prop, but what it can do is horrifying. This is very well realised with spooky music (courtesy of Dudley Simpson) and inventive direction. It is a truly terrifying moment when the machine gains the ability to move. The World Peace Conference is depicted as being mired in distrust and the Master's actions will turn that distrust into hostility. One problem is that these two aspects are not integrated together in the story- it is never made clear why the Keller machine was built (plotwise, it's a sci-fi threat in what is otherwise a straight action thriller). However, they are both realised very effectively, which compensates for this. It is interesting to note the very '70s liberal' attitude to Maoism- the Doctor is friendly with Mao Zedong, who caused the deaths of millions of his people in The Great Leap Forward and then turned to destroying their minds in the Cultural Revolution. Don Houghton puts forward an intelligent script, despite the plot problems.

Timothy Combe again shoots action scenes with filmic flair. The storming of Stangmoor Prison is a fantastically lavish set piece and the use of a full sized missile prop gives the story a very glossy feel. Indeed, the prison is a very effective location, giving the story a very grim feel. The supporting cast is great, with Pik Sen Lim being excellent as Chin Lee and Neil McCarthy being very sympathetic as Barnham. Jon Pertwee strikes a balance between the serious, determined Doctor of season 7 and the more light-hearted one of Terror of the Autons perfectly. Katy Manning as Jo manages to be both sweet and an effective UNIT agent. Delgado again effortlessly makes the Master suave yet twisted. Here he is outfitted like a Mafia boss, riding around in a limousine, chomping huge cigars.

The story does repeat itself (especially when it comes to cliffhangers) and contains some padding- again, this would probably have worked better as a 4-parter. However, it is utterly compelling throughout and well worth a look.
