"Hold it now, last one." "Okay, you can relax." "Oh, good." "I didn't know standing still could be so exhausting." "Would you like some coffee?" "Mmm, please." "How long have they been gone?" "Oh, I don't know." "A couple of hours, I suppose." "I hope they're all right." "Oh, of course they are." "Probably got themselves lost or something." "What's so important about these, er, circuit things you were telling me about anyway?" "Well, they're all part of the..." "Well, it's a sort of machine that we travel in." "Oh, you mean..." "You mean a sort of electric car?" "Well, it's a bit more sophisticated than that." "Oh, well, anyway, I hope you're gonna stick around for a bit." "I get sick of photographing myself." "Oh, why don't you always use a model?" "Can't afford it." "I've only just got enough cash to buy all the junk I need for the camera." "It's an expensive business and, well, I'm not good enough to be a professional yet." "Well, I think you're very good." "These photographs of you are splendid." "Oh, yeah, they're great but I didn't take them." "I was just the model." "That's how I earned the loot to pay for all this." "Oh, I see." "You're still worried about your two friends, aren't you?" "Yes, a bit." "They can't have got themselves into any sort of trouble, can they?" "Oh, you wouldn't say that if you knew them." "If there's trouble to be found, the Doctor and Jamie can't miss it." "Well, what do we do now, Doctor?" "Accept the situation, Jamie." "Nothing else we can do." "Well?" "For a Head Research Assistant, Gregory," "I expect a little more coherent a reply than an enigmatic shake of the head." "I'm sorry, Mr Vaughn." "I've never seen anything like these before." "Given time, I might be..." "Then take time, my dear fellow." "Right, Mr Vaughn." "Take one hour." "Packer." "Yes, Mr Vaughn?" "Packer, those two uninvited guests we had this morning," "I assume they were photographed?" "Yes, sir, security cameras will have taken visual recordings, sir." "Have some prints taken and sent up to me." "It's great, isn't it?" "I bought it off a barrow in the Portobello Road." "Oh, yes." "What's the matter?" "Don't..." "Don't you like it?" "Oh, yes, it's fine." "You're still worried about your two friends, aren't you?" "Why?" "Oh, I don't know." "I've just got this feeling that something's happened to them." "Why on earth should it have?" "No reason at all, really." "It's not a logical conclusion, just intuition." "Well, I'll tell you what we'll do, then." "We'll go right out after them, okay?" "Oh, yes, please." "But we'd better leave a note for them, just in case they come back when we're not here." "Okay." "I'll go and get my coat first." "Would you mind telling us what all this is about?" "You'll find out, sir." "Sir?" "All right, Benton, thank you." "Sir." "NAAFI break, sir?" "Very well." "How nice to see you again, Doctor." "It's Colonel Lethbridge-Stewart!" "Ah, Brigadier now." "I've gone up in the world." "Of course, the Yetis." "We met you in the..." "That's right, McCrimmon, in the Underground." "Must be four years ago now." "That long." "It only seems like a couple of weeks ago, doesn't it?" "I've told you over and over again, Jamie." "Time is relative." "Are you still making a nonsense of it, Doctor, in your..." "What was it called?" "Tardis?" "Yes, we're still travelling." "Yes." "Yes, Mr Travers told me all about it." "It's, um..." "Well, it's..." "To say the least, an unbelievable machine." "Any more unbelievable than the Yetis, hmm?" "No, true." "I'm not quite so much of a sceptic as I was since that little escapade." "But what's all this, and why all the cloak and dagger stuff to bring us here?" "Yes, I'm sorry about that, but my chaps have to be a bit melodramatic in their methods." "But I'll explain." "Oh, do sit down." "Thank you." "How nice." "Oh, Sergeant Walters!" "Yes, sir?" "Lay on some tea, will you?" "You'd like some tea, wouldn't you, Doctor?" "Oh, thank you, and a patty cake biscuit." "Thank you." "Yes, well, since the Yeti do, I've been in charge of an independent intelligence group that we call UNIT, that's United Nations Intelligence Taskforce." "You mean you're like a..." "A world secret police?" "Not quite." "We don't actually arrest people, we just investigate them." "What about us?" "I mean, you arrested us." "Not really." "You see, my men were keeping a watch on the International Electromatic Headquarters when you two showed up." "I've been keeping a check on everyone going in that building." "Your photographs were transmitted to this Headquarters and I recognised you." "Well, what's so odd about people going into the building?" "Oh, nothing odd about them going in." "The problem is some of them haven't come out." "Looks like a robot reception." "Yeah." "Yes, this is probably the same idiot machine that answers the telephone when you ring up." "International Electromatic Company." "State your business." "Enquiry." "Reference two persons seeking information concerning the whereabouts of Professor Watkins." "Wait, please." "Has the information been considered?" "The images of the two humans have been analysed and registered." "They are known and are hostile." "Hostile?" "How can that be?" "Have you been on Earth before?" "No, they have been recognised on Planet Fourteen." "They are dangerous and must be destroyed." "Planet Fourteen?" "But how?" "They must be destroyed!" "Yes, I'll deal with them." "Plans for invasion are nearing completion." "Nothing must be allowed to interrupt them." "Don't worry." "Nothing will." "Nothing must be allowed to interrupt them." "Now listen to me, you stupid, primitive machine." "I asked a perfectly simple question and I expect an answer!" "No information available." "It's no good, Zoe." "I will not be beaten by this brainless tin box!" "But you can't do anything about it." "Can't I?" "A little problem in ALGOL, I think." "In what?" "ALGOL." "It's a sort of language you talk to computers in." "Now watch!" "International Electromatic Company." "State your business." "Begin." "Real X sum positive, delete square." "Begin sum two, subscript J." "That's ALGOL?" "Integer compute." "Printout Y to the minus X variable one." "I'm enjoying this." "International Electro..." "Go to finish." "Continue, integrate on inverse sine." "Oh, it seems to be getting a little bit heated." "You bet." "This equation is insoluble." "Zoe, I think you ought to stand back." "Now, continue printout continuous integration." "Packer!" "Yes, sir?" "Reception." "Two young girls." "Bring them to me." "Right, Mr Vaughn." "It'll take more than a soldering iron to put that right." "Hey, don't you think we ought to get out of here before somebody gets annoyed?" "Oh, yes." "I think perhaps you're right." "This is Gordon Jones, lecturer in physics, Churchill College, Cambridge." "Next one's a chap I knew at Sandhurst, old Billy Rutlidge." "He's got himself a very cushy number at the Ministry of Defence." "And all these people went into the building, the IE building, and didn't come out." "No, no, most of them came out again, but there was something definitely odd about them when they did." "Odd?" "Yes, old Billy Rutlidge, for instance." "He was quite co-operative about my investigations of Vaughn initially, but after he'd been to the IE Building, he started getting a bit sticky about it." "Doctor, would you look at that one!" "Do you know this man?" "Yeah, he gave us a lift in his lorry." "When did you last see him?" "This morning." "This man's an agent of ours." "His report is almost twelve hours overdue." "Ah, well, he did say something about some security guards on his tail." "I expect he's all right." "He was all right this morning when we left him." "Um, Brigadier, tell me more about this" "International Electromatics setup." "Well, there isn't much to tell." "The head of the group is a man named Tobias Vaughn." "Oh, yes, we've met him." "A nice man." "He gave me this." "Jamie." "Oh, yes, that's just the small stuff." "Put it away." "They control practically all of the major computer lines." "They made their real breakthrough in micromonolithic circuit designing." "Undercutting practically everyone else on the market." "But what's your interest in this?" "Well, I knew a little about Vaughn before his sudden success." "I put out a routine check on him and we came up with one or two things of interest." "Like the disappearance of Professor Watkins." "Yes." "Ah, see." "I..." "I don't suppose you have any authority to search the building, have you?" "No, Vaughn's too powerful, he's got too many top people on his side." "You see, Doctor, I daren't make a move against him unless I have good reason to do so." "Well, it looks to me, if Jamie and I want to find the Professor, we'll have to do it in our own way." "That's about the sum of it." "However, should you find yourself in any difficulty..." "Sergeant Walters!" "Yes, sir?" "Got a TM-45 handy?" "Yes, sir." "Right here." "Is that a tank?" "Oh, no, no." "My units are on constant alert, so should you find yourselves in any trouble, you can just give us a call." "Jolly good!" "Here you are, sir." "Thank you, Sergeant." "Now, this is a small transceiver, range of about fifty miles on a set frequency." "Just press this button and ask for me." "Oh, yes, that's splendid!" "Yes." "This should come in very handy." "Call me anytime." "I'm usually available." "Now I better lay on transport to get you two back to London." "No." "They must have gone out." "Zoe?" "Isobel?" "Probably gone for a walk." "Look, Jamie, sandwiches." "I'm hungry." "Want one?" "Thank you." "You know, Doctor, that chap Mr Vaughn doesn't seem such a bad man." "Oh, Jamie!" "How can I think when you've got that thing on?" "Hey!" "All right, all right." "Don't break it." "All right!" "I just want to have a look at it, that's all." "Oh, yes." "It's an interesting little piece..." "What?" "Well, well, well." "What have we here?" "What do you mean, "What have we here?"" "There's a micromonolithic circuit in the back plate of this radio." "Well, what's that?" "It's a very complex circuit in miniature." "What's so odd about that, then?" "It has nothing to do with the radio, as far as I can see." "Oh, Doctor, just put it back together again!" "All right." "I don't suppose Zoe would have left a note, do you?" "No, I can't see anything." "Well, you might at least help me look for it." "I suggest we try the wall." "Eh?" "Isobel never writes anything on paper." "You can't lose a wall, remember?" "Oh." "Ah! "Tired of waiting." ""Gone to IE offices to look for you." "Zoe and Isobel. "" "Jamie!" "We better go after them." "You and your friend, the Doctor, have caused me some considerable trouble today." "First he breaks into this building, and then you ruin a very expensive device." "Only because the stupid thing wouldn't tell us what we wanted to know." "Ah, yes, Miss Watkins." "You're concerned about your uncle, aren't you?" "I'd like to know where he is, yes." "He's perfectly well, I assure you, although a little, uh... uncooperative at the moment." "Your visit here is most opportune." "I think that you can be very useful to me." "Me?" "But..." "But how?" "Your uncle needs to be "persuaded" to continue his work for me." "But I can't do anything about that." "No." "But I can." "Now..." "Packer, I'd like you to take care of these two young ladies, please." "Take them!" "Thought that we were going in there to look for Zoe and Isobel." "There's no one in there except that stupid computer, and that won't tell us anything." "But how are we going to find out if they're in there?" "Well, if the Brigadier's men are still around, they should have seen them go in." "Hello?" "UNIT to operations, over." "Hello, could I speak to the Brigadier?" "Stand by, out." "What a splendid little toy this is, Jamie." "Aye, but it doesn't play tunes like mine." "Yes, Doctor." "I've got a report here on two girls." "About 1 9 or so." "One of them dark, one of them fair." "One of them was wearing very distinctive clothes." "Zoe." "Doctor, that could've been Zoe." "Jamie,just a minute, please." "Brigadier..." "Yes?" "These clothes..." "Did they include a rather brightly coloured feather boa?" "Yes, the little dark one was wearing that." "They friends of yours?" "Yes, I'm afraid they are." "Doctor, come on, let's get after them." "All right, all right,Jamie." "Brigadier, uh, we're going to try and get into the building and try and find them." "Yes, well, be careful." "You may not be so lucky this time." "Call me if you get into trouble." "Thanks." "Right, over and out." "Is it wise to let them go in alone, sir?" "I mean, they don't exactly sound like professionals to me." "Don't underestimate them, Jimmy." "They may look like amateurs, but that man has an incredible knack of being one jump ahead of everyone." "If there is a safe way into that place, he'll be the one to find it." "You were right, you know." "This does lead into the back of the place." "Yes, of course, Jamie." "Come on." "I'm sorry, sir, but these circuits don't make sense." "The material isn't any known metal alloy." "In fact, the structure's more that of a plastic." "What's more, the connections seem to be completely illogical." "Hmm." "How very interesting." "This strange Doctor intrigues me more and more." "I can do some more tests on the circuits if you like, sir, but..." "No, I think I know the answer, Gregory." "You can go." "Yes, sir." "I need more data about this man you say you recognise." "This Doctor." "It is enough that you know he is hostile." "He must be destroyed." "You said you recognised him on Planet Fourteen." "How is this possible?" "These questions are unnecessary." "He must be destroyed." "That is for me to decide." "You will obey." "You forget I control the operation from Earth!" "Unless that's clearly understood, our partnership will cease." "Tell that to your leader." "It has been agreed." "I felt sure you'd be reasonable." "Now, you say you recognise this Doctor on Planet Fourteen." "How did he get there?" "He has a machine." "What sort of machine?" "We have no more information." "But he must be destroyed." "The invasion must succeed." "It will." "The Doctor will be taken care of." "I shall see to that personally." "That's incredible!" "What?" "The ease with which that man carried that crate." "Probably empty." "Let's go and see." "That man must be a superman." "It's odd, Jamie, it's distinctly odd." "There's someone coming!" "It's amazing." "Yes." "Come on, let's find Zoe and Isobel and get out of here." "These fellas are giving me the creeps." "Yes." "Yes?" "They're back again, Mr Vaughn." "The Doctor and the boy." "Security eye has picked them up in the warehouse." "That's rather unfortunate for them, isn't it, Packer?" "Shall I put a full security alert on, sir?" "No, Packer." "We don't want to frighten them off, do we?" "Just close off the area and we'll flush them out." "Have you dealt with the two young ladies yet?" "No, sir." "I was about to when this new alert happened." "How fortunate." "We need a sprat to catch our mackerel." "Take them down to the warehouse area." "This place is like a maze." "Doctor, I think we're lost." "There must be a door to the main building somewhere." "Zoe and Isobel!" "Come on." "Right!" "Put them inside!" "Load it onto the return van." "Come on!" "No, Jamie." "Wait." "Guards!" "Guards!" "The guards!" "Come on." "Like rats in a trap."
