"Shh, listen!" "It's coming towards us!" "Stop!" "We're friends!" "Stop!" "Hickman, he's dead!" "They killed him!" "Came from the sea..." "The sea..." "A sea devil!" "Come on, Jo, quick." "Give me a hand." "It's all right, shh." "We've got to get him into that cabin." "Hickman." "Monster..." "Come on." "All right." "Sea devil..." "Now, easy." "The sea monster..." "Yeah, come on, don't worry." "Get yourself down here." "That's right." "Mind your head." "Mind yourself." "That's it." "Hickman..." "Shh." "Where's your radio?" "The radio, where is it?" "Over here?" "Hickman..." "Shh..." "Ripped it out." "Took it away." "Yes, they certainly did." "Yes, it's all right." "Devil..." "Sea monster..." "Shh." "Monster..." "Yes, yes, yes." "Now, listen to me." "Take this swab, Jo." "Swab his arm." "Now, are there are more transmitters on this fort?" "No, nothing..." "Any transistor radios, that sort of thing?" "I think so." "The crew's quarters..." "The crew..." "What do you want to do?" "Listen to Night Ride?" "It is possible to turn a receiver into a transmitter, you know." "It is?" "Yes." "It's simply a matter of modulating the signal." "You connect the output of your loudspeaker into the input of your low frequency amplifier, and you connect the output of your low frequency amplifier into your oscillator." "You use your loudspeaker as a microphone," "and there you are." "Ah." "Now, where exactly are these transistor radios?" "Crew's quarters, down the corridor, next deck." "All right." "Thank you." "Now, don't worry, this is not going to hurt you." "All right?" "Now, you'll soon be all right." "Hickman..." "Soon feel better." "Look after him, will you, Jo?" "Yes." "Shh, come on, now, try and relax." "Come on." "That's it." "Don't be alarmed." "I've no wish to harm you." "Now, wait, we must talk!" "How do you feel now?" "Would you like a nice hot cup of tea with some sugar, hmm?" "What are you doing?" "Wire." "Doctor, what is going on?" "Just as I thought." "Reptiles, like those creatures in the caves." "It's completely hostile." "Here, hang on to this, tight." "Hang on." "Right." "Well, now what are you doing?" "Those creatures can cut through anything." "Rock, metal, anything." "Look!" "Give me a hand." "Where are we going?" "We've got to get after that creature." "Now, come on." "Keep trying." "Morning, Blythe." "Good morning, sir." "Anything in?" "We've had this report from civilian police, sir." "That man who was here yesterday, trying to get over to the fort, seems to have disappeared with the boat he came in." "Oh, no." "He and the girl were seen heading out to sea yesterday afternoon." "There's been no sign of them since." "Well, get onto the fort and see if they've wound up there." "I've already done that, sir." "The fort just wasn't answering." "I can't raise them at all." "Well, we'd better take a look around." "Get me Air Sea Rescue." "How's it going?" "Nearly finished." "Just about to test it." "Hmm, I've seen things like that in a modern art exhibition." "You don't honestly think you can transmit with it, do you?" "Certainly I do." "I'll prove it to you." "Right, here goes." "Hey, there, early birds, we've got a wonderful batch of discs for you this morning!" "So, don't feel isolated and cut off from the world." "Whoever you are, wherever you are, we've got something just for you!" "Hey, that was my favourite DJ!" "I think I must have got me wires crossed somewhere." "Here's your tea." "Thanks." "Doctor?" "Hmm?" "Those things that attacked us, you said you'd seen something like it before." "Something very similar, certainly." "They emerged from some caves in Derbyshire." "The Silurians, wasn't it?" "The Brigadier was telling me." "That's a complete misnomer." "The chap who discovered them must have got the period wrong." "No, properly speaking, they should have been called the Eocenes." "That was that race of super reptiles that had been in hibernation for billions of years, wasn't it?" "That's right, and if you want my opinion, there's another of their colony right here beneath us." "Well, something seems to have woken them up." "Probably the rebuilding of this fort." "But I thought you said they lived in caves?" "Well, this is a different species, completely adapted to life underwater." "And they've been sinking the ships?" "Very likely." "Why?" "I mean, why are they so hostile?" "What have we done to them?" "Well, they still think of Earth as their planet, Jo, and they want it back." "As far as they're concerned, man is just an ape who got above himself." "Right, I think that should do it." "Let's have another go." "Hello, hello, mayday, mayday, mayday!" "This is, er..." "This is..." "What is this?" "What's our call sign?" "Oscar Bravo Tango 7-4." "Hello, mayday, mayday, mayday, this is Oscar Bravo Tango 7-4." "We are stranded on this fort and have a wounded man here." "Can you send immediate assistance?" "Can you hear me?" "Can you hear me?" "Over." "Doctor, you don't think you'll get through to anybody on that old lash-up, do you?" "Hello, Oscar Bravo Tango, I am receiving you loud and clear." "I am about to land." "Over." "It works!" "Hello, Oscar Bravo Tango speaking." "Who are you?" "Who are you?" "Over." "It's a helicopter!" "Yes." "Well, though I say so myself," "I think that's a remarkably efficient piece of work." "Right, put it over there." "Here we are, then." "Splendid." "None too easy getting hold of something like this at a moment's notice." "Had to send one of my chaps to the mainland." "Said it was for theatricals." "How very ingenious." "Nothing to it." "Just have to use the old loaf, you know." "When do we leave?" "As soon as possible." "How can I go to the Admiralty with a story like that?" "Sea devils!" "If only you had some proof." "What about the two men on the fort?" "One of them was killed, but the other one saw the creature." "Yes, get on to sickbay, will you?" "See if he's conscious yet." "Sickbay, please." "Oh, hello, Captain Hart's secretary..." "Even you must admit that something happened on that fort." "Well, perhaps one of them went berserk and attacked the other one." "But we saw it, too, remember?" "You may..." "Well, Blythe?" "He's still delirious, and he's babbling something about sea devils." "You can go to the petty officers' mess." "I'll send for you later." "Very good, sir." "Squad, eyes right!" "Eyes front!" "About turn!" "Squad, halt!" "Well, did he say why he wanted to see me?" "Oh, all right, you'd better send him up." "All right then, Doctor, let's assume that" "I accept the existence of these sea devils." "What do you want me to do?" "To begin with, we must make every effort to make contact with them." "But you claim that they're responsible for sinking the ships." "It may still be possible to find a peaceful solution." "We're not dealing with animals, Captain Hart, we're dealing with intelligent beings." "Have you got a minute, old chap?" "Thanks so much." "Want a word with you about the golf tournament." "Good heavens." "Colonel Trenchard." "Doctor." "Miss Grant." "Thought you two had left the island yesterday?" "Well, we didn't quite manage to get away." "Taking a look round the island?" "Charming spot, isn't it?" "Sorry to bother you, John, old man, but it's about the weekend." "We are rather relying on you, you know." "Well, of course, I'll do my best, but if we get a bit of a flap on, then..." "That's just what I was thinking, so perhaps it would be as well if I arranged to have a reserve standing by." "Yes, why don't you do that, Colonel!" "Captain Hart is likely to be very busy from now on." "Yes, life is rather full at the moment, George." "Exactly." "So as I was passing, I just thought, old John's going to pretty tied up with all these ships sinking." "Is it fair to ask him to play golf in the middle of something like this?" "So, I said to myself, "What I'll do is, I'll just drop by and sound him out. "" "You see, time's getting short, and I've got to get cracking." "I'm sorry, sir, but should I know you?" "You certainly should, Chief." "Had you not been warned of my coming?" "No, I'm afraid not, sir." "Special audit, Ministry of Defence." "Special audit, sir?" "Yes, the items in this bag here are defective." "Did you realise that you were carrying defective supplies here, Chief?" "Look, I'm sorry, sir, but do you mind if I see your pass, please?" "Captain Hart's preparing it right now." "He'll be bringing it down right away." "I see, sir." "Well, then, you won't mind if I just phone and double check then, will you?" "What exactly are you suggesting, Chief?" "I'm not suggesting anything, sir." "I'm just obeying orders." "You will obey my order, Chief Petty Officer!" "Your order, sir?" "You will obey me." "You have seen my pass and it is quite correct." "Your pass..." "You have seen my pass." "No, I've got to phone and check." "Now, don't worry, George." "If I can't make the tournament, I'll let you know in plenty of time." "But you do understand?" "I don't want you to feel under any pressure about this." "If you want to drop out, I suppose I could rope in old Harry, eh?" "Well, perhaps that's for the best." "Now, if you don't mind, George..." "At the same time, I don't want you to miss the game." "I mean, we'd much rather have you if you can manage it." "Well, I'll do my best." "Now, goodbye, George." "Yes, yes, of course, I see how busy you are." "Yes." "Staying down here much longer, Doctor?" "It entirely depends how long it takes me to conclude my business." "Good day, Colonel." "Yes, yes, of course," "I mustn't hold you up." "Uh, goodbye, Miss Grant." "It's been a great pleasure to see you again." "Goodbye, Colonel." "Well, I'll..." "I'll be pushing off, then." "Oh, thanks very much." "I'll be in touch, George." "Yes." "Now, then, Doctor, where were we?" "Where were we indeed?" "Ships must be kept away from this area." "Doctor, those are major shipping lanes." "We'd have protests from all over the world." "You'll have even bigger protests if ships go on sinking." "And even if we do declare it a prohibited area, how are we going to enforce it?" "You know what happens in the English Channel," "Trinity House marker buoys are ignored half the time." "You'll just have to patrol the area, won't you?" "What are we supposed to do..." "You don't seem to realise how dangerous..." "Doctor!" "What?" "Doctor, come here." "Jo, please!" "Not now!" "Doctor, it's the Master!" "What?" "Where?" "Down..." "But it was him." "Look, I know it was." "Captain Hart, I suggest that you order a full security alert immediately." "Would you mind telling me what this is all about?" "Miss Grant has just seen a very dangerous criminal in your base!" "Doctor, I've been very patient with you, but if I thought..." "Sir, someone's been found unconscious in the sonar stores." "Come on." "I don't know." "He was taking equipment, sir." "Said he was doing some special audit." "Well, I went to phone up to check, and that's when he hit me." "What did this officer look like?" "About my height, he was dark and he had a short beard." "You see?" "The Master." "Who is the Master?" "How did he get in here?" "He's supposed to be locked up." "Trenchard." "What?" "Well, don't you see?" "He arrived just before this happened, and he left a few moments ago." "Of course." "All that silly talk about a golf tournament." "Are you suggesting that George Trenchard is mixed up in all this?" "Yes, I certainly am." "Captain Hart, can you lend me some transport?" "Well, of course I can, but what's it all about?" "No time to explain now." "Come on, Jo." "In conference." "Colonel Trenchard." "Hello, old chap." "What are you doing here?" "I have reason to believe that your prisoner has escaped." "Nonsense!" "Is it?" "See for yourself." "There you are, you see?" "Safe and sound." "Well, he may be here now, but half-an-hour ago he was at the naval base." "Impossible." "Must be a case of mistaken identity." "I'll tell you what, though, I'll go and check the guards myself." "Yes, you do that." "Yes." "All clear." "Try and get an outside line." "No, they're both completely dead." "Now, listen, Jo," "I want you to take the Jeep, go down to the naval base and call UNIT." "Tell them that Colonel Trenchard and his entire staff" "are to be replaced immediately." "But, Doctor..." "No buts, Jo, just do as I ask." "What about you?" "Now, don't worry about me." "I'll stay here and keep an eye on him." "Now, you hurry." "But the girl saw you!" "Oh, it could only have been a fleeting glimpse." "Convince her that she was mistaken." "I tell you, they don't believe me." "The Doctor knows." "Very well." "In that case, suggest to the Doctor that he come down here and see me for himself." "What's the good of that?" "I'll tell him exactly what we're doing." "I'll convince him to keep quiet." "Could you?" "Yes, yes." "But I must see him alone." "I don't want any guards." "You leave everything to me." "I'll put the Doctor's mind at rest." "All right." "I suppose it's worth a try." "Ah, I think there's something wrong with the air-conditioning in here." "Now, that grille seems to be blocked." "I've seen the guards." "Everything's in perfect order..." "Fore!" "Bless my soul." "You were saying, Colonel?" "Yes." "Where's Miss Grant?" "Oh, she's gone back to the naval base." "Oh, I see." "Look here, old chap, if you're worried, I suggest you go and see the prisoner yourself." "Oh, I've just seen him." "What?" "Yes, on there." "Oh!" "Yes, quite." "But if you're in any doubt," "I'd sooner you interrogated the man yourself." "You know the way, don't you?" "If you insist." "Trenchard here." "There is a Miss Grant on her way down to you." "She is not to leave!" "Why, Doctor, so you came for a chat." "Been out for a little jaunt, have you?" "I beg your pardon?" "Why did you go to the naval stores and steal those electronic spares?" "How could I possibly go anywhere?" "You know very well that I'm a prisoner." "You've got some sort of hold over Colonel Trenchard." "What's going on?" "I can see that I shall have to tell you everything." "Good afternoon!" "Like that, is it?" "I wouldn't do that if I were you." "That's government property." "I always find that violent exercise makes me hungry." "Don't you agree?" "Then you'd better enjoy your meal, Doctor, because it might be your last." "Oh, you think so?" "You're good, Doctor, but you're not good enough!" "Ah, but you haven't seen the quality of my footwork yet!" "How many times have I told you?" "Violence will never get you anywhere."
