It’s the end. But the moment has been prepared for …
Logopolis is a story I both love and hate all at once. A fitting end to Tom Baker’s seven seasons as the Doctor, I remain unable to watch this story without believing that maybe, just maybe, if I wish hard enough the Doctor won’t die at the end of episode four. But he always does, it’s always heartbreaking, and I am always moved by Baker’s calm implacability as he acknowledges his time has come to a close … and a new season is about to begin.
Tom Baker provided many iconic moments in his time as the Doctor, and it was only fitting that he should be given a truly dramatic sendoff. Having escaped his old nemesis the Master in the previous adventure we find a melancholy and brooding Doctor, possessed of a strong sense of foreboding and deciding that he needs to fix the chameleon circuit on the TARDIS. As he proceeds to source the measurements required to recalibrate the circuit by measuring an earth Police Box, he discovers that the Master has escaped from Traken, and is following every move he makes. More unsettling still, is the presence of a ghostly Watcher, who seems to be just as determined to follow the Doctor.
The story may be entitled Logopolis, but it is not until a good way through episode two that we actually arrive on the titular world. If anything however, this build up makes the climax even tastier, as the Doctor explains to Adric the principle of Block Transfer Computation – creating matter from pure mathematics, and how this ought to restore the chameleon circuit. The Master may make his actions evident throughout the opening two episodes, but it is not until episode three that we see Ainley, channeling the spirit of Roger Delgado, and gloating at his apparent triumph over the Doctor. For ultimately Logopolis is a story of one Timelord chasing another – the Doctor fleeing to Logopolis, hoping to evade the Master, and the Master hiding his TARDIS within the Doctor’s TARDIS so that he can find Logopolis, which he understands to possess a great secret.
The story builds to a dramatic climax, as it is revealed the Logopolitan mathematicians were using their skill for Block Transfer Computation to excise entropy from the universe, and stave off the end of all matter. The Master’s interference brings their project to a halt, and introduces overwhelming entropy that begins to destroy the entire universe. The impending catastrophe forces the Doctor to form an unwilling alliance with his oldest enemy, as they aim to restart the Logopolis programme from a new home on Earth.
Such a dramatic story would be overblown in just about any other context, but as the finale for Tom Baker it is perfection. So grand is the scheme that one easily loses track that this was also the first story to feature Janet Fielding as Tegan, who stumbles into the TARDIS by complete accident. Sarah Sutton also (clumsily) returns in episode 2 after the production team decided to keep Nyssa as a permanent companion, giving a foretaste of the crowded TARDIS that was to undermine Season 19.
The reason they are easily overlooked is entirely valid however – everything is building up to the climax of episode four. Whatever listlessness Baker displayed in the previous two seasons is lost, and he rises marvelously to the occasion of his swansong. To me, his portrayal of a Timelord contemplating regeneration is only bettered by Peter Davison in The Caves of Androzani, as he manages all at once to combine a melancholy foreboding with a stoic acceptance. This anticipation is accentuated through the role of the mysterious “Watcher” – a character all in white who mainly watches from afar, and who is mistaken for “The Master” (Adric) or “A friend of the Doctor” (Nyssa), and is revealed at the very end to be nothing less than the Doctor’s future, unregenerated self.
There is something wonderfully moving about the final five minutes of Logopolis. Baker foils the Master’s plans to hold the universe to ransom, but in so doing falls to his death. As he lies helpless, surrounded by his companions, he sees each of his prior companions from Sarah-Jane to Romana, before smiling, and telling his friends that the moment is prepared for. The music rises to a crescendo, the Watcher merges with the Fourth Doctor, and the bright young face of the Fifth Doctor emerges. I may think that The Caves of Androzani is a better Doctor Who adventure, but Logopolis is nevertheless the best regeneration story.
It was the end. But the moment was prepared for. And it was brilliant.
