"I want to talk to Barbara Wright." "Susan?" "Barbara, they made me call you." "Who, Susan?" "Who?" "Barbara, listen there was... ah!" "Susan?" "Susan?" "Are you there, Susan?" "They're...they're going to kill me." "Su...?" " We must tell Tarron." " No." "Well what else can we do?" "We've got to find her." "Yes, of course we have, but..." "You're thinking of the Doctor?" "He mustn't know anything about this." "He must keep his mind absolutely clear in order to concentrate on Ian." "Anyway, how do we know that Tarron isn't implicated?" "Who'd suspect the Chief Investigator?" "He was next to Aydan in court when he was killed." "What do we do, Barbara?" "We find Susan ourselves." "And remember, whoever is behind this kidnapping is either in league with the murderer or is the murderer." "Trouble is, where to begin?" "Best thing we can do is to go over everything that's happened to us since we landed in Millennius." "There's a link somewhere and it's probably the one and only way to save Ian." "How much longer?" "Execution is set to take place when the pointer reaches the star." "Will I be allowed to see my friends?" "I've got it." "I've got it!" "What?" "What is it?" " Well it's a start anyway." " Go on." "Aydan is the only one we know for certain who was connected with the crime." "He knew all the others though, that's probably why he was killed." "I don't see how that helps." "Well they must have been in contact when they were planning the robbery." "It's just possible that his wife, Kala, might know someone that he was seeing quite frequently." "But if she did do you think she'd tell us?" "Well, of course she would, she'd be as eager as we are to find the man that murdered her husband." "I'm not so sure." "Well it's a chance." "Come on, it's a chance!" "You." "I'm terribly s...sorry to disturb you." "We know what a terrible ordeal you've been through but we think you might be able to help us." "I don't think so, I know nothing." "Oh please, may we come in?" "If you must." "Thank you." "The people who murdered your husband have kidnapped Susan, the young girl who was with us." "They've threatened to kill her too." "We thought it was possible that you might know someone that your husband was seeing quite frequently." "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's 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." "I'm sorry but you see, you're our only help." "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..." "I just can't help you." "I know nothing!" "I'm sorry." "Come on." "Please understand." "We had to try." "Goodbye." "Your friends were here looking for you." "No, don't look hopeful." "They've gone, they won't be back." "They're like all the rest of them." "Stupid!" "Stupid." "Yes?" "The trial has just ended." "Chesterton is to be executed at the beginning of the next zenith." "Good." "The old man didn't say where the key was hidden?" "No." "I'm certain he doesn't know." "I'll get it later then come for you." "Be ready." "I will." "What about the child?" "She's no more use." "Now she can identify you, now." "Kill her." "We cannot delay telling the Doctor now." "Oh, we should have told him long ago." "Sabetha you were right." "If anything happened to Susan I'd never forgive myself." "It was a terrible choice." "She sounded so afraid." "What is it?" "What you just said." "Kala couldn't have known!" "Known?" "Known what?" "What are you talking about?" "Kala said, 'You must have been sick with worry since you spoke to Susan.'" "Well how did she know we'd spoken to Susan?" "We've told no one." "Then Kala must have been with Susan when she telephoned." "Yes!" "Come on, we're going back." "Seems a pity really." "The old man didn't know where the key was hidden after all." "Let me go!" "Let go of me!" "Let me go!" "Don't struggle!" "Oh, Barbara!" "Don't take it so hard." "Oh, ha, it's you." "I just wanted to say what a good job you did on the defence." "Yes." "And you did an even better job on the prosecution, my man." "I'm sorry we couldn't have met under happier circumstances." "Yes, yes." "Goodbye." "Goodbye." "Oh, excuse me." "The exhibits and documents." "Where do you want them?" "In the cupboard, please." "Well." "I don't think there's anything else." "Goodbye." "Goodbye, sir." "It's time to leave, sir." "Leave?" "I can't leave now." "I must find new evidence and reopen the case." "Yes?" "I'd like to speak to Interrogator Tarron." "This is Tarron." "This is Barbara Wright." "Have you had the results yet on the gun that killed Aydan?" "No, not yet." "Well just to save time, I'll tell you what they say" " Aydan was killed by his wife, Kala." "What?" "I'm with her now." "Why don't you come and get her?" "Come on." "...So we realised that Kala couldn't have known we'd talked to Susan." "Yes, and the three of them crept up behind her and wham!" "We shouldn't have taken the chance, though." "I had no right to risk Susan's life." "Perhaps not, perhaps not, however the child is safe and well." "I wish I could say the same thing about Chesterton." "But surely they'll stop the execution now that Kala's confessed?" "I hope so." "I sincerely hope so." "Well?" "Well?" "Kala's made a full statement." "She's named her accomplice." "Ah, then you can stay the execution." "No, I can't." "Kala's sworn testimony states that the man she was working with was Ian Chesterton." " Impossible!" " But she's lying!" "Yes, I have doubts myself." "She's a vicious, dangerous woman." "But just doubts aren't enough to s...ask for a stay of execution." "We need positive proof." "What about that man that called her on the phone thing?" "I heard him tell her to kill me." "You didn't recognise the voice?" "No." "What else did he say?" "Oh, nothing much." "Just that he'd collect the key later and...and then pick her up." "Collect the key... ?" "Yes, yes, do you understand?" "The villain that planned all this, the one who planned this whole affair is now planning to collect the key!" "What a wonderful opportunity it gives us to catch him red-handed... and to release Chesterton!" "You!" "Call the prison." "Oh, the key!" "How did you know it was there, Doctor?" "Well it had to be." "I knew it all along." "Until we knew the culprit, the information was no good." "Everyone and everything that went in or out of that vault was checked." "Everything except this mace." "Have you any idea why they did it?" "Oh yes, they've owned up to everything." "Kala and the prosecutor had planned to steal the key and sell it." "And Chesterton here just happened to walk right into the middle of it." "They made him look so guilty I never doubted for a moment that he was the one." "You should read Piro, my boy." "He founded scepticism, a great asset to your business." "Well, thank heaven you remembered reading Piro, Doctor." "Reading?" "What are you talking about?" "I met the man." "Whoopee!" "Now we can go and join Altos and Sabetha." "Have you sent them on ahead, Doctor?" "Well there was no point in keeping them here so I thought it might cheer Arbitan up to know that we'd been successful." " Good idea." " Yes, well it's been lovely for him to see his daughter again." " Oh, yes!" " Well, not only that, you see..." "The Senior Judge has just written this." "Ah, is that the authorisation?" "This gives you permission to take the keys out." "Thank you." "All we need now is the wrist strap you impounded from Chesterton." "Ah, thank you." "I see you're all wearing them." " What are they for?" " Our means of travel." "They do look a bit odd but they work." "They give us movement through space." "I don't believe it." "Show him." "All right." "Now?" "Ready." "Steady." "Go." "Well, one of them might have waited for me." "However, I suppose I'd better join them." "I don't understand." "Where have they gone?" "Goodbye, my friends." "He's gone too." "Yes." "He told us what was going to happen and we saw it." "But nobody else has seen it." "We'd be better off keeping this story to ourselves." "How are you going to complete the report, Tarron?" "I shall say that... that they left." "They left to take the key back to its inventor, Arbitan..." "Arbitan is dead." "You hear me?" "I, Yartek, am in control now!" "What have you done with Sabetha?" "Where is the final key?" "I don't know." "Why are you so stubborn?" "What purpose does it serve?" "I'm going to find out in the end!" "What have you done to Sabetha?" " Sabetha!" " Why have you tied him up?" "He is of no use to you." "He's just a servant." "He knows nothing, I tell you." "He means nothing to you?" "I have no thoughts about him at all." "I told you, he's just one of my servants." "Let him go." " Sabetha!" " Be quiet!" "I did not give you permission to speak." "I tell you, he knows nothing." "In that case, as you think so little of him, as I gather from the way you treat him, it doesn't matter what happens to him." "Of course not." "Send him away." "Yes." "I can do that..." "Or I can have him killed." "After all, he's only a servant." "Kill him!" "No!" "Useless lies!" "Where is the final key?" "I'll never tell you." "Never." "But this man is no servant." "He travelled with you." "He is in love with you." "I think he will tell me." "The man who loves me cannot betray me." "No, that man that loves you cannot condemn you to death." "I can promise you one thing." "If you do not tell me where the final key is, I shall order my creatures to kill her!" "The man who was with us, the Doctor, he has it." "What on Earth are you doing, my dear boy?" "You frightened the life out of me!" "Doctor, I'm sorry." "Is TARDIS all right?" "Yes, the force field's been lifted and I peered in for a moment or two and everything appears to be all right." " Oh good." " Arbitan kept his promise then." "He said he'd remove the force field." "Yes, come along, come along." "You're all running around here like a lot of scared chickens." "We were waiting for you!" "But I'm here!" " My dear Chesterton, sometimes..." " Grandfather!" "...You drive me around the bend." "I don't know why I..." "Even so, it's a bit odd." "You mean Sabetha not being here to meet us?" "Or Altos." "We'd better keep our eyes open." "I have put them in the cell, as ordered." "Keep well out of sight then now, but be within call." "One more." "Just one more." "Well done Doctor." "I was afraid of this." "Yes, and I think it's time now to go...back to the ship." "What about Sabetha and Altos?" "Yes, they may be hiding somewhere." "Yes." "Right." "We split up." "Susan, you go with me." "We'll go in search of Arbitan." "Doctor, you and Barbara, see if you can find Sabetha and Altos." "Give me the key." "Here." "And don't part with it until you're absolutely sure it goes into the right hands!" "Don't worry, I won't." "Come on Susan." "And you'll accompany my...me, my dear." "Yes, all right." " Look, I think we'll take this with us." " Yes, yes." "Just in case." "It's no use!" "Even if we managed to untie ourselves, we'll never break the gates down." "At least I could defend you." "Oh, I can't even do that!" "At least you're with me, Altos." "Huh, I'll never leave you." "Arbitan!" "Thank heaven, we were afraid." "Have you brought the keys?" " Where's Sabetha?" " Where is the old man?" "He is the one who has the key." "I..." "I don't understand you." "We've done all these things for you and all you can do is think about the key." "Forgive me." "The keys have filled my mind for so long," "I have become insensitive to anything else." "Sabetha is safe and well." "Do you realise that the..." "Stop!" "Don't come near me." "Power from my machine escaped." "I am suffering from a deadly disease." "Can we do anything to help?" "Sabetha alone knows the cure." "Where is Altos?" "The young man who attached himself to her while she was away?" "Is he a good man?" "Is he sincere in his feelings for her?" "Well, what is your impression of him?" "There are many races of men on Marinus." "He looks and sounds well enough." "But I don't know..." "Well, naturally we like and admire him." "But since you don't know him you must make up your own mind." "I agree, of course." "But the key - the final key - do you have it?" "Yes." "Ian..." "I have it here." "Throw it down." "Good!" "Now bring the old man to me." "Sabetha will be here and we can enjoy our triumph together!" "All right, I will." "Shall I follow and destroy them?" "No." "The machine will enslave them now." "Bring Sabetha and the young man to me." "I want them here when the final key is inserted and my power is absolute!" "Ian, that man couldn't have been Arbitan." "No." "I thought Arbitan sent Altos for the keys." "This man said he was a stranger." "He never looked at us." "I think there was something funny going on there." "But then why give him the key?" "Ian!" "So when Yarteks gets the final key, his power will be absolute." "Yes, with the aid of the machine he could control us all." "And our impulse to leave this planet would be destroyed." " That is true." " Altos!" "Sabetha!" " Sabetha!" " Altos!" "You heard about Arbtian?" "Yes, we met the man who's usurped his place." "Uh...uh, give me the key and we must have it destroyed." "Well Ian gave it to him." " What?" "!" " What?" "You gave it away?" "I gave him a key." "Sabetha, you remember that fake key?" "Barbara found it on the idol." "I remember." "That was the key I gave him." "This is the genuine key." "My dear boy!" "We must go, quickly!" " Leave the building!" " Why?" "Yartek may put that false key into the machine at any moment." "If he does it will set the machine in motion, but once it feels the full force of the power it...it'll break under the strain." " You mean the machine'll blow up?" " Yes..." " Along that corridor, come on!" " ..." "And everything in this building!" "Through the moving walls!" "About where you are, Susan." "What do you mean, 'about'?" "Don't you know exactly?" "Somewhere here, somewhere here." "It was a small stone, it moved under my hand." "Yes." "Why haven't you obeyed my commands?" "Where is Sabetha?" "The others have set them free." "They are in the corridor near the cell." "She will have told them of her father's death, of course." "But it doesn't matter." "The machine's power will spread through the planet." "There is no escape now, except for us!" "I will bring them back with this." "Everything all right, grandfather?" "Yes, my child, chase the others up will you?" "Right." "I'm glad to have this moment alone with you Sabetha." "I want to speak of your father." "You know, he was a very wise and brilliant man and I know how you felt when you learned of his death." "And his life's work destroyed." "Oh no, no, no, no, I wouldn't say that." "His work will go on only not quite in the same way." "But I don't believe that man was made to be controlled by machines." "Machines can make laws but they cannot preserve justice, only human beings can do that." "Now I only hope that you'll carry on his good work, please?" "Goodbye." "Bless you, my child." "What are you going to do now?" "Well we might well return to the city of Millennius." "We still have our travel dials." "It's a good place to start." "Susan!" "We've got to go now." " Goodbye Sabetha." " Goodbye Susan." " Goodbye Altos." " Goodbye Susan." "What shall I do with this key, the one I didn't give to Yartek?" "Why don't you give it to the Doctor?" "That's a good idea." "All right, I will." " Goodbye Barbara." " Goodbye Altos." "We shall think of you often." "Ian." "Goodbye Altos." " Goodbye Sabetha." " Goodbye Ian." "Take care of her Altos." "You may depend on that." "Oh dear, I shall miss them." "Come on, Barbara."
