This episode doesn't have much happen, but there's quite a bit of Troughton flexing his mental muscles; he works out a complicated formula regarding the gas and he also tries to work out the purpose of the gas. He, Jamie, and Polly have been sent to work in the mines, which pump a huge amount of gas for an unknown purpose. Ben is still working for the colony under hypnosis, but he's starting to break free of their influence a bit. And Jamie manages to find a way out of the mine into a disused shaft, where he encounters some Macra. And that's basically it; it doesn't sound like much, but it is an entertaining episode -- hearing Troughton at work is a delight, and you wish you could see it. Here, more than anything that's come before, is the first real instance of Troughton's Doctor as we know him, where he finds the right balance between quiet humor and quiet investigation. No slamming heads on tables or dressing up as old beggars here.

Still, this is a story that seems very visual -- there are lots of sequences of throbbing heartbeats and quiet music with no dialogue to illuminate what's going on, which suggests that this is another one of those stories that we really need to see to evaluate. But unlike, say, The Celestial Toymaker, what we have on the soundtrack inspires confidence. In a story about paranoia and possession that's also about giant crabs, there's an element of subtlety that's rather lacking, but what we get instead sounds like a solid, entertaining tale.
