"I can sense them all around us now." "Doctor!" "Doctor..." "Steady Chesterton, steady...the calmer you are, the stronger." "Doctor, look at these two." "Maitland?" "Maitland!" "Can you hear me?" "Fear my boy." "It's loosened his mind and it gives the Sensorites the chance to control it." "Doctor, that thing's still out there." "Oh ignore it!" "Maitland!" " Yes..." "I hear you." " There's work to be done my boy!" " Work, understand?" " Work..." "He's responding!" "There's a door to be opened, remember?" "A...door, er yes!" "Danger on the other side." "John, ah yes..." "We must get the two girls out!" "Good, good, good!" "All we want you to do is to open the door." "No!" "I'll protect you." "But our friends are out there." "They're dead, all dead." "But we were just with them" "Just a few minutes ago." "What is it?" "They're here." "Inside here!" "John, open the door." "Frighten them?" "No, I can't do it!" "No...no!" "Somebody's talking to him - inside his mind." "No, don't force me. ..." "You can't!" "I won't do it!" "My head!" "Pain!" "Why is this, why is this, why is this?" "Somebody's ordering him to do something I know they are." "Something to harm us!" "I'll have to use the cutter." "Oh not again!" "How long will this take?" "It's the only way." "Yes, I know..." "Just that I'm so worried about Barbara and Susan." "Now-now-now, try and contain your emotions; use self-control." "Otherwise it confuses the brain and leaves it wide open to an attack by the Sensorites." "Look at Maitland here - fear and inertia has left him vulnerable!" "Yes that's true enough Doctor." "The Sensorites are in the ship now." "What?" "How did they get here?" "Through the loading bay." "But that can't be where Barbara and Susan are now..." "No, but we must get to them as soon as possible." "Oh nobody's arguing about that!" "But that man John's with them, and..." "The Sensorites have control over John's mind, they may force him to obey their orders." " How's it coming?" " Slowly, but it's working." "If I only knew what was happening on on the other side of this door!" "Barbara!" "Susan!" "Listen." "It's coming from the outside." "Yes, I can just hear it." "It must be Ian trying to get through." "Yes." "Give me your hand." "They want me to frighten you, I mustn't give way." "Oh he's so tense Barbara, can't we help him." "John, we're not afraid." "Not afraid?" "Not while we have you to protect us." "It's quiet and peaceful here." "There-there's no real danger." "The Sensorites..." "We're you're friends John." "Friends..." "No, they are my friends!" "Barbara I've got an idea." "Yes?" "He's quiet now, but we can't be sure that the Sensorites won't make him help them." "Look, if they can use their brains, why can't we use ours?" "To defend him?" "Yes, and ourselves." "Look, Grandfather and I landed on a planet once called Esto, the plants there used though transference." "If you stood in between two of the plants they set up a sort of screeching noise;" "Grandfather said it was because they were aware of another mind." "...Breaking in on their communications." "Yes exactly!" "I thought if we both tried together..." "Well anything's better than just sitting here." "Sensorites!" "They're nearer now." "You see, if we both think of the same thing at the same time." "Well what do you mean?" ""We defy you", something like that?" "Yes, yes "We defy you"." "Alright." "Now we must both picture the words very clearly in our minds." "We must both concentrate very hard." "Ready?" "Yes." "When I count to five." "One..." "Four...five!" "Oh, it's jammed, we'll have to cut the whole section out!" "We can't wait." "I'll give you a hand." "Wait a minute." "That's it..." "It's going..." "Yes it might be possible for Susan's thoughts to reach out to the Sensorites." "So we really can resist them?" "Yes, and there's that friend of yours, John." "We must look after him." "Aah, let me see now..." "Oh course er they have a hold on his mind you know..." "Oh, he's sleeping peacefully now." "Ah, Yes." "I wonder...did Susan relieve the pressure?" "I-I heard hundreds of voices in my mind Grandfather." "Oh yes, and that was a stupid thing to do Susan!" "Because you were strong-willed and without fear they didn't harm you." "He's resting now." "Did you know his hair was almost white?" "Ah, there's nothing wrong with that." "In a man of thirty, Doctor?" "And he looked so old!" "Why have the Sensorites done this?" "What do they want from us?" " I..." " Doctor?" "John muttered something before he passed out." ""The dreams of avarice."" "Now on Earth we have a saying: "Rich beyond the dreams of avarice."" "I think he's discovered something." "It would explain why he's had the worst of it from the Sensorites." "Yes, er..what were John's duties?" "W-he's our mineralogist." "You see, makes sense." "John mumbling something about riches" " I think he must have discovered something that the Sensorites wanted to keep secret." "So they silenced him, and kept all of you prisoners about their planet." "I see." "And now they're trying to do the same thing to us." "We must get the lock of the TARDIS back." "Have you tried talking to them?" "Talking to them?" "!" "Yes, we must try - we must!" "The First-Elder is communicating, be alert while I listen." "Yes, the First-Elder is interested in human voice which said "we defy you"." "The human creatures that are newly arrived seem to possess more intelligence than the others." "The First-Elder said they have less fear of us." "We are to stay here and watch and listen to them closely;" "if they try to attack us with force we are to summon our warriors to destroy them." "One spectroscope Doctor." "I do remember that he was beginning" " ...to take a reading of the minerals in the vicinity." " And then what happened?" "Well that was the first time that the Sensorites attacked us." "Would you like to look at that graph for a moment?" "Yes." "Oh, there's nothing much here..." "Pretty ordinary collection of things:" " Oxygen, hydrogen, sodium..." " Oh what's that?" "Oh, it's a spectrograph Susan." "You see those lines, they represent the emission wavelengths that..." "Oh yes, course." "Mm..." "No there certainly isn't anything special indicated on this." "You're very strange people." "Are we?" "Well you come from nowhere and you seem to be going nowhere." "Oh we're very dependent on the Doctor - he leads and we follow." "Travel without a purpose?" "Oh no, there's a purpose in it." "He's trying to get us back to our own time on Earth." "Oh I see." "Isn't it better to travel hopefully than arrive?" "Oh anything's better than circling around a planet forever and being kept alive." "Alive..." "It's been more like a living-death." "I just don't understand, there must be a clue here somewhere, there must be." "Well I dunno Doctor." "Certainly isn't much here." "Well I studied it whenever I could, but it didn't look like anything that would cause much excitement." "The Sense-Sphere is just an ordinary planet with a slightly bigger land mass than usual; but er, that's all." " Yes, that's very interesting." "Er, may I?" " Certainly." "Excuse me." "We know that the Sensorites have discovered thought transference." "And when John discovered something, he became so excited that his mind opened up and he broadcast it to the Sensorites." "And it was something they wanted kept a secret." "What...what is this?" "What was it Chesterton said?" ""Rich beyond the dreams of avarice."" "Yes, of course, of course." "I know what he found!" "Molybdenum!" "It's all here in the graph, but it's all mixed up with the lines so it doesn't make obvious reading." " Molybdenum?" " Yes." "It resists very high temperatures." "Yes, it's used in an alloy in steel, in fact this machine would be useless without it." "Now let me see, iron melts at er... 1539 degrees centigrade;" "and molybdenum melts at 2622 degrees centigrade." "So you know, that er, will give you some idea." "Yes I see now just what John found, no wonder he was so excited." "That planet must be full of it - full of it!" "Yes, a veritable goldmine!" "Sensorites!" "They're here, on this ship!" "Come on Barbara, let's find them." "Where do you suppose this leads?" "I dunno." "Let's find out shall we?" "You needn't come if you don't want to." "Nonsense!" "Open the door." "Go and find Maitland, ask him how to lock this door." " But Ian, you..." " Go on, don't worry about me!" "Go on!" "Tell me how do we lock the doors?" "Please try and concentrate!" "The sick member of the crew, try him." "Oh, he'll be in no condition to help." "Do as I say!" "John, show me how to lock the doors." "The Sensorites are on the ship, we must stop them." "Ian, no!" "Why not?" "How else am I supposed to keep these creatures off?" "Well do you need to keep them off?" "Have they actually attacked you?" "Come on John, lock the door." "It can't open now." "It's strange, they didn't harm you?" "No, I think that they were as frightened of me as I was of them." "Then they're not very aggressive are they?" "No." "Come on, let's get back to the others." "The others...the other way!" "The Sensorites can get through that way!" "It's beginning to clear now." "Bolt the door John, bolt it." "Now we'll see what the Sensorites can do." "This is all very well, but I think that one of us should try to contact them." "Are you feeling better now?" "Much better." "Oh I don't know what happened, but I'm certainly feeling better now." "I'm sure it's no coincidence that the Sensorites attacked as soon as you discovered the molybdenum." "Yes, but they won't agree to that." "...Agree?" "To what?" "What are you talking about child?" "I-I'm sure they'll talk to you about it..." "Susan, what is it?" "Alright, I'll ask them. ..." "I'll tell you later." "The Sensorites want to know if it's alright for them to talk to you." "Are you saying that you're in tou..." "Do you mean to say that you've made contact with them?" "Yes." "Well of course we shall see them, but they must agree not to harm us." " Right." " If they try to harm us then I shall fight them." "Which one is the Doctor?" "The one with the white hair." "Speak up, I can't hear you." "We have been speaking to each other." "What is it you want of us?" "Why won't you let these space-people go back to their Earth, mm?" "None of you can ever again can ever leave the area of the Sense-Sphere." " Why not?" " You know the answer to that!" "Because of molybdenum." "We are not interested in it!" "So you say, but once before we trusted Earthmen - to our cost!" "So Earthmen have visited the Sense-Sphere?" "Yes." "And they caused us a fearful affliction." "We shall not allow it to happen again." "What do you expect us to do, drift around forever?" "No, you will all come back with us." "A special area has been prepared for you on the sense-Sphere." "There you will live and there you will be looked after." "These people cannot possibly accede to your request, it's out of the question!" "You will do exactly as we tell you because you have no choice;" "none of you!" "My party does have a choice, and I assure we have no intention of spending the rest of our lives with you!" "Well you have our answer." "What do you propose to do?" "We intend taking you down to the Sense-Sphere, but we do not wish to harm you in any way." "Since we've met you we have no wish to harm you." "But you must get off this ship." "What if we refuse?" "We will attack you." "The other Earth people will not be able to help you." "Surely we've proved that we don't need help." "You have only proved that you can lock doors." "We can unlock them!" "Now listen to me both of you." "You've taken the lock of my ship and I want it returned immediately." "You are in no position to threaten us." "I don't make threats, but I do keep promises" " and I promise you I shall cause more trouble than you bargained for..." "If you don't return my property!" "We must decide what we shall do." "What did they mean decide?" "I dunno, sounds as though there's something else they can do to us." "Oh they might have been referring to Susan." "The Sensorites only spoke to me." "Next time - if there is an next time" " they might try and control your mind child." "Like they have to these two people." "Doctor, is there no way you can get into your ship?" "No, not unless they return what they stole from my ship." "But will they'll never give it back to you!" "Oh my dear, they're not invincible, no-no-no." "Did any of you notice the peculiarity in their eyes?" "No I can't say I did." "It's a fallacy of course that cats can see in the dark, they can't;" "but they can see better than we humans because the iris of their eyes dilates at night." "Yes..." "What are you driving at Doctor?" "Oh, it's all perfectly simple Chesterton, you see the Sensorites eyes are the exact opposite to that of a cats." "The Sensorites eyes were completely dilated, that is enormous in light." "Conclusion, is that they would contract in darkness." "Exactly, and that is our best weapon!" "The Sensorites will be frightened in the dark." "But you can't be sure of that." "You're only sure that they can't see in the dark." "I very much doubt, my child, that they can see in the semi-darkness." "But Doctor, assuming you're right..." "Which he is of course." "Naturally." "Then how can you be sure that the Sensorites will be frightened of the dark?" "My dear Barbara, wouldn't you be afraid if you couldn't see your enemies, mm?" "Thank you for your admiration my dear boy, thank you." "Well I never said a word!" "Ha-ha, telepathy!" "You know telepathy isn't only a prerequisite of the Sensorites." "I know sometimes what you're thinking!" "I don't want to go." "My dear what..?" "They're talking to her again." "What are they saying?" "Ssh!" "I-I can't hear them very well." "Oh that's better, there-there's just one voice a long way away." "What's the message child?" "Oh..." "Oh alright." "But none of the others must be harmed." "Don't move any of you." "Grandfather it was the only way, they knew I'd agree." "Agree?" "To what?" "To go down with them to their planet." "Otherwise we'll all be killed."
