Another novelisation of a TV story scrapped at the last minute, The Ultimate Evil doesn’t have quite as much promise as The Nightmare Fair. And that’s putting it mildly. Even without a hiatus blatting out a whole season, it’s difficult to believe this would ever have reached TV screens.
There are some okay ideas in it. A world is under attack from a “hate ray” which drives people into a murderous rage at whoever they happen to be with. More interesting, and quite funny, is the way they cope with this: everyone voluntarily chains themselves up and the next person along holds the key. When they’re sane again, they let each other out. The routineness of this makes for a fun SF conceit, but that only takes the story so far. The actual people are completely uninteresting, and that’s down to the story: they don’t NEED to be interesting or complex when an external force keeps transforming them into crazy people. Very few characters have actual motivations beyond not wanting to hurt each other, or wanting power.
The Doctor and Peri (the former written about as brusquely as Colin Baker could get on screen, and that’s BEFORE the murderous rages) saunter into this hoping for a holiday, and are immediately in danger. Promptly separated, Peri meets Lorca, a young man who was caught outside during a hate ray attack and pushed his fiancé off a cliff. Peri then goes with him to the same cliff. Guess what happens next. (What was she expecting?) Not the first, or last instance of a character behaving stupidly here.
In general the characters (including the Doctor) just go from place to place having their feelings dictated by the Evil Dwarf Mordant (just “Mordant” would do but we’re reminded he’s a dwarf several times), sometimes in an almost farcical manner where it switches on and off between rooms. None of it says anything about them, despite some half-baked philosophising about there being evil in all of us which the hate ray highlights. Very deep I’m sure, but this actually being sci-fi, it would perhaps have made more sense to add in a line about brain chemistry. It would feel less wishy-washy than just firing random emotions through space.
Another villainous character has a “hypno-gun” which means he can control anybody - as well as being a tedious contrivance, that made me wonder why Mordant bothered with the long-winded scheme at all and didn’t just hypno-gun a few kings. (Or the bloke he’d given the gun to, for starters, whose cooperation is key.) Other characters have the ability to teleport anywhere at will, and a major plot point concerns the impossibility of a character lying - only he’s able to do it anyway, without explanation. Some of these ideas are not inherently stupid, but they are merely thrown in there without any development. See also, the anticlimactic and silly showdown between the Doctor and Mordant, where he basically tells him off and Mordant goes away. To terrorise somewhere else, presumably? Oh yes, very satisfying.
There are some bursts of decent prose, but it’s mostly workmanlike, including plenty of explaining-what-they’re-going-to-say-before-they-say-it just before a bit of dialogue. And the dialogue is generally pretty silly, at one point boiling down the problem to: “Someone, somewhere, has now discovered the key to our cupboard of deep-buried badness.” The whole thing is just a bit embarrassing.
