" What's it been like, being Lucas North?" " Get away from me." "You're alive." "And you're suddenly stirred once again to the defence of the realm?" "I want to get clean." "And I encourage your reapplication, Miss Bailey." "Have you told Harry Pearce what we did?" "I need a file." "It's in Five's archive." "It's called Albany." "It's been 15 years, John." "Don't talk to me like you know me." "I'll accept the position of Section Chief." "I want complete clearance on all my operations." "Grade-A access." "Why did you decide to turn up now?" "I had to see you." "This is a security announcement." "Please ensure that your personal baggage is kept with you at all times." "Oh, it's early." " I thought you might need to be getting back." " He's at a conference today." "Work needs me." " I don't even know what you do, John." " Private security consultant." "Makes sense." "Obscure, mysterious." "Yeah, well, it's not as exciting as you think." "Anyway, Dr Lahan, the last time I saw you, you were thinking about opening a tapas bar." "I'd forgotten about that." "It was a long time ago." "Hey." "What are we doing, John?" "We're doing what we were always supposed to do." "The cress is sprouting late this year, Junren." "Very funny." "Listen, we had the best turnout ever at Tuesday's meeting." "Ten 'Free Tibeters'." "Dozen human-rights bods." "Hardly going to topple the party, is it?" "Thanks for coming." "I know this isn't easy for you." "I can't stay long." "I need to get back to the embassy." "Kai, please would you think about actually coming to a meeting?" "Our group campaigns for democracy in China, but it's been years since a member actually set foot in the country." " lf we could get an actual party official..." " No..." "Look, I really feel that we're gaining momentum." "I feel that you could inspire us to the next level..." "You know my position." " I'm with you." "Just not..." " With us?" "Yeah." "Remember something, Clare." "You're asking me to risk everything when you risk nothing at all." "First in for the meeting." "Someone's trying to impress." " I owe them a bit of impressing." " Teacher's pet." "How's your asset?" "He's politically on side." "But still loyal." "Just not quite ready for the next step." "We've had a code-red Border Agency report." "The UKBA database has flagged up three high-level CSS operatives entering the country yesterday on fake British passports." "These three are a Chinese State Security undercover cell." "They're an aggressive unit that specialise in assassinations and high-level industrial espionage." "There's no precedent for this, so we have to assume that it's something important." "And their cover identities are due to leave the country in three days." "So whatever they want, they want it fast." "That's why we need good intel now." "Sorry, my asset's a slow burner." "She needs more time..." "That's not good enough." "Beth?" "Kai is very promising." "Ideologically, he's committed and personally." "His brother protested at Tiananmen and disappeared." "Chinese assets are notoriously hard to turn." "If there's the slightest chance that we can flip a CSS officer inside the embassy, then we have to take it." "If he needs to be pushed, then you push him." "But gently." " I think I can do it." " Think or know?" "I can turn him." "It may just be my epic hangover, but I fail to see the urgency." "Home Secretary, there are a million Chinese spies in the world." "We've spent years trying to just turn just one of them." "Even so, I advise caution." "Our relationship with China remains delicate." "Chinese State Security seem to have no problems sending three high-level field operatives to London." "Oh, we don't even know what they're here for yet, Harry." "No need to be so sabre-rattly about it." "So we should simply roll over for the bigger dog?" "If you roll over, you sometimes get your tummy tickled." "I don't think they put the hazelnut syrup in." "Home Secretary." "Bang!" "Bang!" "Bang!" "Bang!" " Mr Beecher." " Sir Harry." "I love that." "Please, "Harry", "Harry" is fine." "I see you're plunging into the indigenous cuisine." "It's the vinegar." "Who knew?" "I wanted to talk to you about the Chinese." "Any CIA dealings with CSS in London currently?" "CSS, huh?" "No." "I'll ask my people." "Anything I should know about?" "We're not entirely sure what it is we don't know as yet." "One of your unknown unknowns, I suppose." "I bet it's industrial espionage, and I'm not talking toasters." "Chinese are raising their game." "Any thoughts on potential treasure?" "I'll look into it." "I'd advise you tread on Chinese toes softly right now." "Trade, Taiwan, human rights..." "They're antsy." "You wouldn't wanna upset them." " Not as much as we have, anyway." " Oh, we don't like to upset anybody." "Alpha two, turning this asset could be our only chance of finding out what the CSS want." "Understand Kai as a person, but see him as an asset." "He's just an asset." "Nothing more." "Play whatever emotional cards you've got." "You look... awful." " Listen, I'm really sorry about last night." " Hey, don't apologise." "You know I want change in China more than anything." "But betraying my country..." "You wouldn't be betraying China." "Just the people in power." " Let's walk." " Okay." "I've got something to tell you." "I need you to stay calm." "My name isn't Clare." "Give her a chance." "Oh, no." "I'm dead." "No, no, you're alive and you're brave and you can help your country." "You don't understand." "If I'm seen with a British spy..." " You haven't been." "We've been careful." " Never contact me again." "Never." "If you want true freedom, then you're gonna have to take risks." "You know as well as I do that China is only headed in one direction." "More oppression and more control." "Spare me the rationalisation." "You are not interested in that." "You lied to me." "Pretended to care." "Pretended to share my beliefs." " He's walking." " Shit!" "Alpha two." "I'm not gonna lie to you." "I know that you want to help." "And if you do, I promise you, everything I tell you from now on will be the truth." "Have some professional courtesy." "If you're going to play me, you need a better strategy than this." "This isn't a strategy!" "You're the first agent I've ever tried to turn." "I have no idea how to do this!" "If you're so inexperienced, then why are you my recruiter?" "Because you're not that important." "Look, I'm sorry." "I told you, I'm not gonna lie to you." "Goodbye, Clare." "Exit stage right." "He's gone." "Okay, come home, Alphas." "We need something on what that Chinese team is here for." "We've no idea what they're planning." "There is something else we could do." "Get hold of the CSS data archive." "Ready?" "Okay, Tariq, ready for the trembler switches." "I'm gonna cause a localised power surge to knock out perimeter security systems for a moment." "It'll only be a blip inside the building." "They won't even notice." "A moment?" "When I say go, you'll have 1.8 seconds to open the window." "Ready." "Go!" "Stop!" "Okay." "Breathe in." "What have they got?" "They've found the most recent archive." "Kept offline on 3D optical discs." " Makes it completely unhackable remotely." " Good." "You have no idea how pleased I am to hear..." "KAl:" "You have people in the embassy." "You know I can't tell you anything." "KAl:" "They're about to be caught." "An alarm has been tripped." "Alpha one, I've just received intel from Kai." "The Chinese are onto you." "He came through!" "Copy that." "We're leaving." "Wait." "Alpha two, do you believe him?" "Yes." "Either way, they're onto you." "Get out now!" "If you're caught, there's nothing we can do to protect you." "I've got guards down here." "You need to find a new exit." "Any ideas?" "Alpha two, we have to use Kai." "Your call, Alpha two." "Can you get our people out of the building?" "We'll protect you." "Are you with us?" "KAl:" "Put me through to them." "I'm patching through Kai." "We're in the northwest-corner meeting room on the third floor." "KAl:" "Okay." "There's an interconnecting door opposite the window." "Now turn right." "At the end of the room, there's a concealed door leading to a staircase." "Top of the stairs, turn left." "Above you." "That's the only unalarmed access to the roof." "Okay, I'm hanging up." "Hang on, wait." "We can't both go this way." "They'll know we had inside help." "It's your only escape option." "Use it." "Harry, if Kai's a solid asset, he's too valuable to lose." "It won't take the Chinese long to work out who helped us." "I'll find another way out." "Ruth, alert the police posted outside the embassy." "Anonymously." "You saw someone breaking in." "Going off comms." "Go." "Police, please." "Don't shoot!" "Don't shoot!" "Who are you?" "Listen, mate." "I didn't realise this place was..." "Whatever it is." "Chinese buy the burglar act?" "Probably not." "But I've spent enough of my life in cells, so tell me last night wasn't for nothing." "Well, we found something." "It took me a while to translate the files." " You speak Chinese?" " Mandarin and Wu." "My Cantonese is horrible." "But once I'd finished, one key word kept cropping up." "Amphitrite." "Poseidon's wife." "Goddess of the seas." "Amphitrite is the code name for a new desalinisation technology." "It's super-efficient and ultra low-cost." "Water filtration tech." "Would the Chinese really send in a top assassination team just for that?" "This is the global drought map." "Kenya hasn't had a wet season for four years, and it isn't just a third-world problem." "Australia is dry." "California." "This is what it could look like in 30 years." "So whoever can make seawater drinkable gets very rich." "We traced a connection to QMK Technologies." "They're a biotech company." "They're world leaders in desalination technology and they're based in southwest London." "This is about more than money." "It's about the power to control a basic human need." "Empires have been built on less." "I'll brief the home sec and talk to this QMK." "Beth, you seem quiet." "What's on your mind?" "Kai?" "Yeah." "Listen, running an asset's all about psychology and emotion." "You understand that." "I know." "I'm just surprised he turned quite so quickly." "What, now you feel contempt for his disloyalty?" "Use it." "You trust your instincts." "They've got you this far." "The Chinese wouldn't dare launch an operation like this against a British company." "Why not?" "They have to live up to being the world's premier economy." "And all we do is moan about their censorship and nag them to stop building power stations." "No wonder they're ready to steal from us." "This little island's intellectual property may be the last meaningful global currency we have left." "We have to hang on to it." "Whatever it takes." "Whatever happens, whatever you hear, just stand off." "Let me do this my way." " So you decided to help?" " I almost didn't." "How did it feel?" "Purposeful." "I want to do more." "As soon as I took that first step, it felt right." "I'm not sure if I believe you." "Steady." " What?" "Don't spook him now." "Well, last time we met you weren't exactly whistling God Save the Queen." "And then suddenly you risk everything." "If you're lying to me, I'll kill you." "Did you think everything I told you about my brother, my family, my beliefs, that is a lie as well?" "Listen, I think we might have picked up a tail." "I'll meet you at the lock-up." "Come with me." "I need you to do something." "Sorry about that stunt at your house." "Bit dramatic, I know." "You've got 30 seconds before I hang up." "What do you want?" "Okay, okay!" "I need your help badly." "What?" "And you think that blackmailing me is the best way to get it?" "Look, John." "I made silly promises." "I need that Albany file." "No." "I told you, I'm not doing this." "Please." "They won't leave me alone." "Do this for me and I'm gone." "Forever." "You can carry on with whatever life you want." "Are you committed to the cause of your government?" "No." "Does anyone else know about your involvement with Ml5?" "No." " The tail?" " It was nothing." "I was wrong." "Flying colours." "He's on the level." "So, do I still call you Clare?" "Might as well." "Okay." "What do you want me to do?" "Well, QMK just about stopped short of patting me on the head and telling me to run along." "Thankfully." "I warned them about the threat to their Amphitrite project, but apparently they're very confident in their security arrangements." " Anything from our asset?" " Beth's got him looking into them." "Surely they'd want our help if someone's planning to steal their crown jewels?" "Tariq, we really need to get into their system and find out more about Amphitrite." "Their core files are well protected." "Couple of days to crack them remotely." "If we could use a terminal inside their offices, I could upload an instant hack." " Bypass their firewall completely." " So we go in." "Security's tight." "Have you got a list of QMK contractors?" "Because we'll need to borrow an identity." " Got it." "There's cleaners, temps..." " No, someone with higher access." "Translator?" "Starts tomorrow." " Perfect." " Name's Kendra Scott." "Speaks French, German, Arabic and Mandarin." "Alpha two in position." "Ok, Gazelle." "Officer in place." "Got your back." "Picosecond count still one." "Well, it's good enough for a quark!" "Let's take a break." "I need coffee." "This is Gazelle." "I'm on the move." "We haven't got long." "You try remembering the Mandarin for "quark"." "Fourteenth floor." "Grade-one IT lab." "There'll be a priority access terminal, where you can hack into the system." "Okay, well, there's a guard and a very locked-looking door." "Sorry." "There was no indication that would be secured." "Okay." "Okay..." "Um..." "My God, are you all right?" "No, sorry..." "It's hypoglycaemia." "I need to get to a bathroom, take my shot." "Can you let me..." "I'm sorry, I know you're not supposed to..." "I'll get some relief." "I'll check on you in two minutes, okay?" "Thank you." "Thank you." "Come on, come on." " Kai?" " I searched for QMK on our systems." " Like you asked." "There's a bomb." " Where?" "There!" "At QMK." "We've planted it." "You need to be sure about this." "It's going to take out the whole building." "It'll look like an accident." "Alpha two to all units." "I've just received a report from our asset." "The Chinese have a bomb planted inside QMK." "They could detonate at any moment." "Gazelle." "Get out of there immediately!" "One minute." "They don't want to steal the desalinisation tech, they want to destroy it." "Tariq, jam the mobile networks and GPS signal to the area to prevent remote detonation, and red-flash the Bomb Squad." "Alpha two, prepare to evacuate." "I'm in." "It's moot." "Leave immediately." "Please make your way to the nearest exit." "Okay, Home, you need to hear this." "Amphitrite's not the code name for the desalinisation project." "Amphitrite is its creator." "It's a female scientist." "Chinese born." "Jiang Li." "Do you copy, Home?" "And she's in the building." "Lab T15." "It's an assassination." "Agreed." "Gazelle, find that scientist fast and get both of you out safely." "Okay, everybody out!" "Move as quickly as you can!" "Step away from the building!" "Quickly!" "Move!" "Come, come, come." "Quickly, quickly, quickly." "Miss Jiang?" "Miss Jiang?" " Who are you?" " What are you doing?" "Will you please stop pointing that gun at me?" "Let me see your access card." "There's a fire in this building." "There is no fire." "We've done a thermal scan." "Thermal scan?" "Who are these guys?" "Let me see your access card." "Now." "Come clean." "I'm security services." "Protocol mauve six pelican." "CIA!" "Gold nine cormorant." "If you are Five, you'd better tell me what you're doing here." "Now." "Tell them." "We're investigating a possible Chinese operation against Miss Jiang." "We have a credible bomb threat against this building." "Source?" "A trusted asset in the Chinese embassy." "A trusted asset in the Chinese embassy." "You need to get her out of here." "All right, let's go, Miss Jiang." "You had better be right." "Lucas North, Section Chief." "We need to talk." "We secure the package first." "Okay." "Come with me." "Please." "My son will be okay?" "You promise?" "Yes." "The CIA are very, very good." " Where are we headed?" " Nearby safe house." "Randomly assigned location from HQ." "We don't even know." "We can't really call this relationship special if we don't even talk." "Once I know what's going on, we can get all caught up, sweetheart." "Wait." "You said this location was randomly assigned?" "GPS transmission from our base." " When?" " Just now." "But we jammed the signal." "Target on the move!" "We delivered Jiang directly to them!" "The snatch team knew we'd react to a bomb threat by shutting down the networks, enabling them to hijack CIA GPS." " They just had to sit and wait." " There was no bomb." " So the intel from the embassy?" " It was fed to us." "The Chinese let us steal it." "It gave us the only thing that they knew about Jiang, her code name, Amphitrite." "Which leads us to one conclusion about the entire operation..." "Kai's a triple agent." "We've been on the end of their rope from the start." "We've been manipulated by a foreign superpower on our own soil." "Not only ease, but with contempt." "There's no way we could have known." "We may have a small window of opportunity to turn this round." "Bring Kai in quickly and quietly before he has a chance to disappear." " I'm sorry about your lip." " Don't be." " You couldn't have predicted this." " I couldn't have got it more wrong if I tried." "Tariq, have you got our phone tracking logs from yesterday?" " I can get them." "Is there a problem?" " I'm sure it's just a glitch." "Lucas followed a suspected tail onto the Tube yesterday and he got on at Queensway." "But the Central Line was suspended all afternoon." "Maybe they restarted it when they saw him." "I mean, he's pretty mean-looking." "I need a code-seven protocol." "You couldn't look it up for me, could you?" "Listen, don't worry, I'll do it myself." "Thanks, Stephen." "The CIA operation." "No wonder QMK stonewalled me." " And you didn't think I should be in this loop?" " Part of the deal, I'm afraid." "CIA run Jiang's protection, no Five involvement." " Beecher lied to my face." " That's spying for you." "Look, the US lose 300 billion dollars every year to Chinese industrial espionage." "It occurred to them that some of that filthy lucre could be flowing the other way, with the handy by-product of stemming China's escalating economic clout." "By poaching Chinese scientists?" "We fit in how?" "We house them, we get a share of the spoils." "We're the Guantanamo for boffins?" "Amphitrite made the decision freely." "She's a British citizen now." "Don't underestimate the value of that." "And if her technology works as promised, then our share in it will safeguard our energy supply for decades." "Oil-rich countries do tend to be rather water-poor." "A trade." "Water for oil." "So we can keep the Passat running and they can live." " Harry, the Agency wants Kai." " No." "He betrayed us." "We'll deal with him." "I don't want to jeopardise this deal with the Americans." "Which is why we can afford to piss them off only for a little while longer." "Should you get to Kai before they do." "We already know the truth, so you might as well tell us." "I don't understand." "What happened to the bomb?" " What happens to Jiang now?" " Look, I don't know what you're talking..." "So that story about your brother and Tiananmen, was that just to get me on side?" "Do you even have a brother?" "Everything I told you has been absolutely true." "I don't know what's happened." "I have been a good traitor!" "I want Lucas in there." "Where is he?" "I need you to take over from Beth." "She's too close to this." "I've been calling." "Where are you?" "Just been following up a lead on the red CSS van." "I'm on my way." "Lucas." "I've been digging in the GCHQ archive." "If Kai's a triple agent, then we'll have had a cleaned-up file fed to us at some point." "Kai's brother did disappear after Tiananmen Square." "But look who led the police to his hiding place." "Good work." "You can drop the innocent act now." "Why did you do it, Kai?" "Patriotism?" "I don't know what you're talking about!" "You were the one who informed on your own brother when you were 14 years old?" "Yeah, your little friend here has been a party loyalist all his life." "Tell me." "What kind of fanatic gives up his own brother to a state he knows will imprison or execute him?" " You okay?" " Hmm." "I spent hours and hours with Kai." "Listening to him talk." "Feeling what he felt." "I just can't believe it was all a lie." "You came up against a better opponent." "That's all." " And it could have gone worse." " How exactly?" "Well, in this job, um, every day you make it home in one piece, that's a little victory." "Bloody hell." "I can see why they don't let you write the prospectus." "Your instincts were wrong on this one." "But don't stop trusting them after one mistake." "Beth, where are you?" " Kai's flat." "It's bugged!" " We're not monitoring him." "Neither are the Americans." "They're Chinese bugs." "Why would the CSS spy on one of their loyal officers?" "He's Western-educated, he's emotionally compromised because of his family background." "Beth, he's a triple agent." "Yes, he's the perfect triple agent because he doesn't know it." "They used him." "They knew we were cultivating him, so they let it happen." "And when the time was right, they fed him disinformation that he thought was the truth." "Lucas, he's been on our side all along." "All this time..." "I thought I was being brave." "You were brave." "I was stupid, disloyal and weak." "That's why they chose me." "I didn't disappoint." "I'm so sorry." "I was trying to help." "I was really trying to help." "You still can." "Your flat was bugged." "They would have one on your person, but we scanned you on the way in, so it's not with you now." "Do you have a coat, a phone?" "My briefcase." "They're always taking it away for security sweeps." "I know we have no right to ask for your help." "You have every right." "I betrayed you." "Just tell me what to do." " You okay?" " Yeah." "Fine." "Good." "So there's a woman at your embassy." "A scientist called Jiang Li." "Her code name is Amphitrite." "We need her." "Right now, the home secretary is drafting an emergency law which means that we can legally enter and take her back." "All I need you to do is make sure that she doesn't leave before tomorrow." "I'll see what I can do." "Still a vodka man, I take it, huh?" "Come on, you don't need to be so unfriendly." "Hope you covered your tracks." "Did you use a fall guy?" "Course you did." "Didn't have to do that, of course." "You could have taken a risk." "Talked your way out of it." "Harry Pearce would have believed you." "Still, better to be safe than sorry." "Best to set someone up." "Whose life did you ruin today, John?" "Look, I did what you asked." "I helped you." "Now you and I are done." "You didn't do this for me." "You did this for you." "Maya!" "What are you doing?" "You shouldn't be here!" "Listen, I've done it." "You've done what?" "I've fixed things." "Everything's clear." " We can be together." "Do anything." " John, you need to slow down." "Sorry, I just had to tell you." "I don't want to waste another moment." "Okay." "Okay." "It's gotta be forever this time, John." "We're on." "Looks like it worked." "They're taking Jiang out of the embassy." "Get CO 19 into position." "They're loading her into a blue Transit van." "Reg, Victor, two nine six." "Oh, my God, Kai's with them." "They're taking him, too." "Maintain eyeball." "I'm on my way." "Armed Police!" "Jiang, Kai, out of the car!" " Harry Pearce." " This is Shao." "You are interfering with the rightful repatriation of Chinese citizens." "I'm outside Thames House right now." "I've just had a call from the Chinese section chief." "Tell Lucas to hold his position." "Hold position, Alpha one." "Hold." "Awaiting further orders." " It's been a few months, Mr Shao." " I have no interest in playing spies." "You can pretend it's still the Cold War if you want." " In fact, it suits us perfectly." " Down to brass tacks, then." "If you think I'll let you walk away with Miss Jiang, you are making a catastrophic mistake." "We were planning to destroy her research in an explosion at QMK tonight." "A truck, loaded with industrial gases, in the underground car park." "But your act of aggression has forced us to abandon the truck elsewhere." "We will detonate if you don't give her back." "There'll be many casualties." "That would be an act of war, Mr Shao." "Jiang was removed from China on an operation that killed two civilians." "So let us not talk acts of war." "Stand-by, Alphas." " What the hell is going on?" " No idea." "Stay sharp." " I'll talk to the home secretary." " You have 10 minutes." "Ruth, there's a truck bomb somewhere in London." "The Chinese are threatening to detonate it unless we let them have Jiang and Kai." "Harry, it's another bluff." "I don't think so." "Not this time." "Now, QMK would never let a truck into their car park unless it was from an approved contractor." "Get a list." "See if any of them have had a vehicle stolen." "Right." "16 companies." "Only one with any vehicle unaccounted for." "Check out CCTV on the way to QMK." "Find that vehicle." "Last camera pinpointed it approaching Elephant and Castle 15 minutes ago." "Bomb squad will never get there on time." "Dimitri, are you thinking what I'm thinking?" " Clare, what's going on?" " It's okay." "Just stay calm." "The Yanks will crucify us." "Annoy the Americans or risk British lives." "There's no decision here, Home Secretary." "I need you to be sure about this, Harry." "Take it down to the wire." "Confirm the bomb is real." "If it is... give her back to the Chinese." "Got it!" "I've found the van!" "South side of Borough Market." " We need to be sure." "How far is Dimitri?" " Still two minutes." "You are late." "The home secretary is currently over the Atlantic." "Getting through is proving quite difficult." "I'm here." "I can see the van." "You are delaying me to find the truck." "I assure you, I'm trying to get you an answer." "I'm sorry, Mr Pearce." "But with no decision, you leave me with no option." "It's here." "The bomb is real." "Okay, Mr Shao." "You win." "Alpha one and two, stand down." "Alpha three, evacuate the area and liaise with the Bomb Squad." "Guys, I need you to clear this area immediately." "Move away from the area!" "Please!" "Drop it!" "Kai's got a gun." "It's a stand-off." "We may have time to defuse that bomb." "You heard him, Alpha three." "Doesn't look too bad." "The electronics will be hidden, though, near the centre." "Should tell you up front, this is my first time." "Be gentle with me." "Beth, talk him down." "Slow and calm." "Triggers and failsafes will be routed through that circuit board." "You see the chip that's bigger than the others?" " Yeah." " You need to melt it." "Sounds like you just told me to melt the enormous bomb." "It will kill the transmitter and the bomb won't be able to detonate." "Kai!" "Please, just listen to me." "Calm down." "Just take some deep breaths." "Just put the gun down." "There's nothing you can do." " No!" " There's something I can do." " She's innocent." " That's why you can't kill her." "But I can." "Then at least they don't get her." "Be careful not to burn the other components." "Yeah, thanks." "Look, I know they killed your brother, but this is no way to seek revenge." "No, no, I killed my brother!" "He must have triggered the failsafe." " Get out now!" " Just a minute." "I'm nearly there." "What kind of fanatic gives his brother away?" "A boy impressed by words and ideas and lies." "One who, every single day since, has tried to make up for what he did." "This is the only way that we can win." "Don't you dare close your eyes!" "If you're going to shoot that woman, you damn well look her in the face!" "Bomb safe, bomb safe!" "It's over." "The bomb's defused." " Okay." " Thank you, Ruth." "For what it's worth..." "Handing you over to the CIA like a piece of meat..." "None of us want that." "I'm a commodity." "If you're valuable enough to someone, you can never be free." "Still, I have my son." "Do you have children?" "No." " Harry..." " If you don't start knocking," "I'll have to have you fitted with a cowbell." "Everything all right?" "The CIA are picking up Jiang, but Beth asked to take Kai to them personally." "I hate the way we're just handing them over." "Like they're just things to be exchanged and moved around." "Well, we're all being moved around by someone, Ruth." "But I agree with you." "Kai deserves better." "Wish there was something we could do." "Hello?" "If there is anywhere Mr Kai would like to stop off on the way, do make sure he gets there safely." "Okay." "What's wrong?" "Where are we going?" "You tell me." "Take a right up here." "Then the next left." " You can't be serious?" " Just here." "No, Kai, they'll take you back to China." "This is insane." "No, I figured out what my purpose is." " To betray." " Listen to me." "I didn't realise until now, but that's what I do." "I betrayed my brother, my country, your country." "Every ideal I've ever had." "Stop!" "You know what they'll do to you." "Maybe." "But I need to see my parents." " Tell them the truth." "Try and explain." " Their forgiveness is not worth your life!" " Please, Clare." " I can't let you do this." "Just let me have this little bit of control over my life." " Just for once." "Just for today." " This is suicide!" "Don't remember me too poorly, eh?" "Tariq, any news from the Border Agency?" "Three known aliases of the CSS snatch team left the country an hour ago." "They've gone." "Does anyone know Stephen Owen?" "G Section?" "He's been arrested." "He crashed the mainframe and diverted £24,000 from one of our slush funds into his personal bank account." "That's not possible, is it?"

"All Section D operations are now suspended and all resources dedicated to finding this man." "Muatt Hutri." "Commands his own Islamist paramilitary group." "We treat this as a priority-one threat to the talks." "Dimitri, have you heard from Beth?" "Not for a couple of hours." "She's missing." " No, please!" "If the leader of the free world dies on a London street..." "I don't need you to paint me the bloody picture!" "Find this man!"
