After a long spell of listening through the missing stories, I have finally arrived at the classic "Fury from the Deep" and was surprised to find it every bit as enjoyable as fan opinion claims it to be (as opposed to "The Web of Fear", which I found slightly disappointing). There are, of course, no episodes of "Fury from the Deep" remaining in video form, which allows the listener's imagination to take over and, as a result, and thanks to a perhaps unusually high standard of sound design, "Fury from the Deep" also benefits from flawless special effects and dramatic sets.
The recurring heartbeat of the weed creature is a genuinely menacing sound. The motives and origin of the creature are never explored in detail, but there would seem to be parallels with Inferno here, as if nature were rebelling against the human race interfering with its darker secrets. The gradual take-over of the refinery personnel is convincing and the performances are effective, particularly that of June Murphy as Maggie Harris. The story has quite a large cast, which can be a problem on audio, but here the script, performances and audio narration by Frazer Hines are sufficiently well constructed that following the story never becomes a problem.
The only significant weakness of the production is, as ever, Deborah Watling's screaming companion, Victoria. Thankfully, this is Victoria's last story, and for once the writers appear to have remembered that, before meeting the Doctor, she spent a great deal of time in the company of an eminent scientist, and for one small scene her character helps to move the plot forwards. As to her eventual role in defeating the weed creature, well, I shan't spoil it for you, but one has to wonder if the production team didn't have a few quiet laughs when they came up with it!
Whilst not all of the lost "classics" live up to their hype, I think that "Fury from the Deep" does. It seldom feels padded and has, at times, a genuinely creepy atmosphere.
