Soph Watches Classic Doctor Who – The Keys of Marinus  (Part 3 of 3)

By Sophie Iles

The end is nigh! The Key of Marinus quest is almost over, but with a slight hitch. Ian’s being framed for murder and the last micro key has been stolen. Welcome my friends, to the final part of this adventure looking at The Sentence of Death and the Keys of Marinus. I like this serial, but I do feel that the end gets slightly rushed, but I feel that a lot with Terry Nation’s stories — at least these few that I’ve seen. Let’s go through this and find out for ourselves?

As per our cliffhanger, Ian has been set up for murder and theft, found knocked on the head on the floor by the body, fingers all over the murder weapon: a mace, locked in a vault, which he can’t have been allowed access to, where the micro key has been stolen. With all these thoughts in hand he must be guilty. It doesn’t help that in the lovely city of Millennius, the legal system is “guilty until proven innocent”. Doesn’t that make you feel a little uneasy? We after all know the truth, our audience hoping that someone will find evidence to prove his innocence

Of course, they’ve yet to reunite with the Doctor who we’ve not seen for two episodes.

Welcome back Doctor!

When he does turn up there is a little bit of fanfare of course, Susan practically tackles him, and once again you can really see there’s been so much development since these characters met, even between Susan and the Doctor, perhaps, dare I say it, having Ian and Barbara around have left him open up to his more sensitive side?

IAN: Doctor!
SUSAN: Grandfather!
BARBARA: How did you get here? ALTOS: We looked everywhere.
SUSAN: I’m just glad we’re back together again.
DOCTOR: Yes, so am I, dear child. So am I. However, we have some important work to attend to. Excuse me. Chesterton, you and I must have a talk.
IAN: We haven’t much time for a talk, Doctor. In a moment I’ve got to go in there and face an accusation of murder. I need a man to defend me.
DOCTOR: I am that man.


Alas, they still have hard work to do, as Ian needs to be proved innocent, even if the poor man who was murdered, Epiram was a friend of Altos’s, also sent to get the key by Arbitan, makes no difference. Concrete evidence is what they need. Which is why the Doctor promotes himself to defend Ian in court.

This episode really does prove how valuable the Doctor is to the team, despite the fact he’s not been around for almost an hour of this serial, here he is using logic to figure out that the murderer was either the relief guard who found Ian — or in cahoots with him. On meeting said relief guard, Aydan, they discover he’s a bit tetchy, doesn’t like them talking to his wife Kala and when they leave they stay by the door to see him hit her.

So, with this information at hand they pull a trick, claiming the fake micro key is the one they found in Aydan’s office when they call Sabetha for a witness. Aydan’s reaction shows his guilt, but before he can implement anyone else in the crime, he is killed in the courtroom by an unknown assassin. As Kala cries over her dead husband, all of this feeling very little like  a Doctor Who story and more like a satire of any court room case I’ve ever seen, they still believe Ian is guilty, with no proof that he isn’t the one who’s in league with Aydan.

Whoever killed the lad too is stirred up by it, because not long later, The Doctor still trying to plead for more time to find evidence, Barbara gets a phone call (though it looks more like a hairbrush but you’ve got to love 60’s predictions of future technology) claiming that they have Susan and are going to kill her. This ends Sentence of Death, which actually on it’s own is a fine episode, showing a lot of strong moments, but sadly, it’s the second part that I feel rushes through to the conclusion.

Barbara gets a distressing phone call from Susan….



The Keys of Marinus shows us, once again as she has done plenty of times this serial, Barbara takes charge of hopeless situations. She decides not to distract the Doctor, but to try and find Susan herself with the help of Altos and Sabetha, tying the link that perhaps Kala might know Susan’s kidnapper if it was someone her husband’s dealt with. On talking to her however, she cries and exclaims she doesn’t know anything…and without realising it implicates herself in the crime!

KALA: I know of no one. My husband was very secretive. He never told me who he saw or where he went. Now, please, Aydan is dead. If he committed a crime, he’s paid for it. He’s dead, but I’ll have to live with the memory of his crime for the rest of my life.
BARBARA: I’m sorry, but you see, you’re our only help.
KALA: Leave me alone. Leave me alone. I do understand and I sympathise with you. You must have been sick with worry since you spoke to Susan, but I just can’t help you. I know nothing.
BARBARA: I’m sorry.
ALTOS: Come on.
BARBARA: Please understand, we had to try. Goodbye.

After they’ve left she has the lightbulb moment, they never even mentioned about the telephone call to the wife, and therefore she’s the culprit behind the kidnapping! The three of them then sneak back in the flat just before she can murder Susan, to the relief of everybody capturing her.

The next sequence is one of my favourites, Ian has been tried for the murder, and he’s waiting on his sentence, and The Doctor can do nothing but sit and try to wrack his brain. He looks rather upset to have failed Ian, and the development of The First Doctor in this moment, is so heart breaking. A man who’s always rushing off to the next adventure, never staying in one place, and up until very recently had no love for the human’s he’s absconded away on his time machine and yet, despite the fact Ian is sentenced to death, he won’t give up on him or in clearing his name. Though Barbara is about to ring, and change the course of this scenario, the reaction of the Doctor being told to leave, still makes me incredibly proud of him.

TARRON: It’s time to leave, sir.
DOCTOR: Leave? I can’t leave now. I must find new evidence and re-open the case…

The Doctor who failed Ian Chesterton…

But with the revelation that Kala murdered her husband, Susan said that her accomplice would be “along to collect the key” and the Doctor finally realises a way to trap the murderer, because he claims he knew all along where the key was hidden, inside the murder weapon itself.

So, when they catch the prosecutor red handed trying to steal it alone with Tarron of Millennius’s police guard. They not only have the key, but they also have Ian safe and sound back with them so they can return to Arbitan.

Whilst Susan, Ian, Barbara and the Doctor say their goodbyes, Sabetha and Altos go on ahead, to find what was their home with Arbitan taken over by the Voord, and by Yarkek, their leader. He is dressed as Arbitan in his robes, and interrogates the pair about the micro key and it’s whereabouts. Sabetha tries to claim that Altos means nothing to her to save him, but it doesn’t work, and Yartek threatens to hurt the other if he doesn’t get any answers.

The Voord at this point really are a great villain, but with only ten minutes left of the episode, it’s clear that everything is going to be summed up fairly quickly and makes them lacking in reality.

Susan, Ian, Barbara and the Doctor arrive back in the building too with their travel dials, and when they reunite in the corridor, (it is one of the sweetest examples of the friendship of this group might i add) they end up splitting up in search of their new friends and for Arbitan after they attacked by a Voord soldier again. Ian takes the key, and has been told explicitly not to give it over unless he’s absolutely sure, but when he and Susan find Yartek, the Voord claims that it really is him but he is dying of a horrid disease and so covers his hood. For a long and rather annoying moment, I am sure that Ian believes the rouse — until he questions Yartek about Altos when he claims to believe Sabetha had picked up the young man on her adventure, when he in fact had been his assistant.

But even with that, Ian makes sure to leave on a good note. He gives over a key alright, but it’s the dummy key. A key that Sabetha warns will disturb the computer and set it to destroy the building, the supercomputer and everyone inside with it. They all get out of the labyrinth of a building just in time, where Altos and Sabetha hand in hand plan to return to Millennius to live together, whilst the Doctor and his companions have places next to visit.

It’s a lovely way to end the serial, Barbara looking off longingly as their new friends go off to start off somewhere new, whilst Ian taps her shoulder gently to join him in the TARDIS. They’ve settled into this life now of danger and adventure, and it shows despite the obvious wishes to return back to home. It’s a nice ending, but it is still incredibly rushed at the end which for me is it’s only downfall.

So, what’s next week? It’s another historical of course! Join us next week to watch the Aztecs, and how Doctor’s first ever real efforts to make sure they don’t meddle with history starts to take shape.

As for this weeks doodle? You have Sabetha standing up to Yartek. Enjoy!

PS: If you like the idea of the Voord, one of my favourite First Doctor Big Finish Stories is Domain of the Voord and I think it’s one of my favourite Big Finish stories, elaborating on Voord history, lifestyle and religion and some very exciting and terrifying adventures with relatives of Yarket involved.
