Original subtitles

Today is the first day in the trial of the MI5 officer, Officer X.

You will not deviate from the story that's been agreed.

I understand the stakes.

I'd ask you what's going on, but I know you won't tell me.

I'll contact you when it's over.

Whatever happens tomorrow, whatever the jury decides, I love you.

Do you find the defendant guilty or not guilty? Guilty.

A slapped wrist! The sentence was lenient, given the charges.

You implied there'd be no sentence. This was a show trial.

You've got to convince her now. It's up to you.

Chile's a beautiful country, but I won't do it. Take it. Take the passport.

I'll never see you again.

Gone.

No, Gracie, don't do that.

Graham! Let go of him, I said LET GO!

Everything all right? Yeah.

Sort of. I'm sorry. I've just got the worst headache...

They know just when to strike.

Sometimes I think it's not lice we should be looking for but the three little sixes.

Look I'll deal with them, why don't you go take some paracetamol and get some fresh air.

There's some in the first aid room. Yeah. Thanks.

"Look, said Percy the pig. There's the farmer.

"You go and distract him and I'll make a run for the fence."

Oh, you feeling better?

Yeah, sort of.

I'll be fine. Maybe you should sit down. No, no I'm fine, honestly...

Clare, can you hear me? Clare?

Well, did you see her take the pills? No.

What's her medical history? Is she diabetic? Epileptic? No.

Not that I'm aware of. We'd know...

She just said she had a headache.

The bottle's almost full. It can't be an OD.

All right, I want you to call anybody who you think might have some information...

Stop, stop, stop.

She's arresting. Charge 200. Stand clear.

RADIO: '...died this morning, bringing the number of paracetamol related deaths to seven,

'with eleven more victims still listed in serious condition across the country

'including two children aged seven and nine.

'The health secretary made an urgent plea this morning

'for everyone to avoid taking any form of paracetamol while this matter is being investigated...'

Ruth, Danny, meeting room. Now.

This was faxed in anonymously. Everything else can wait.

We've now got nine people dead after taking the most harmless

and commonly used medicine in the country.

I thought it was a cock-up at the factory.

That's a story we're encouraging.

But according to Pharmavor, the manufacturer,

the pills were tampered with intentionally. Tampered?

The pills were laced with a little added ingredient. Menazorphine.

Rather a potent dose, I'm afraid. The combination's lethal.

It's like drinking acid.

We need to look at this as a potential domestic act of terrorism and the clock is running on this,

I don't need to tell you all how pervasive this is already.

I know I've thrown out all my pills,

and it's not the best time of the month for me to do that.

This saying, "As the walls crumble down, so the hawks will feast on the carcasses of the infidel."

What about it?

Well, it sounds more like a calling card than a statement after the fact. They're not finished.

We should be so lucky.

What's this thing down here? What does it mean?

It's a signature. "Al Saa'iqa".

It means thunderclap.

Not come across them before. I need to know if they're real,

if they actually did this, and how it was done.

It won't be easy to authenticate. A lot of cells like this Al Saa'iqa work independently.

I'll have a look at the wording, see if they've popped up before.

Something like this has to have an insider to make it happen.

We need to go over employee lists, recent firings, anyone who might have a grudge against the manufacturer.

Pharmavor... I think they're involved

in some big controversy over their AIDS drugs pricing policy.

Good, work it with Ruth.

I don't need to tell you all, this is strictly need to know.

Until we know exactly what we're dealing with, we're sticking with the official line.

And let their share price be damned.

Better a few pharmaceutical share prices suffer than we start a mass panic.

Yeah. Danny?

Unusually taciturn. Any thoughts?

No, I think you've pretty much covered all the angles.

That's very gracious of you.

PHONE RINGS What is it?

'I'm sorry, sir. There's a call for you.'

They've been known to wait.

'It's Guy Facer.'

By all means, then. 'Please hold for the Security and Intelligence Coordinator.'

Just what we need. Another useless bureaucrat.

When will the government learn we don't need to replicate every mindless position the Americans

and the Tories create?

'We need to meet.'

Hey. Danny?

How are you?

It's sweet of you to ask.

You know, that's what I love about this business.

You know, people, people care.

Everybody just looks out for everybody else in such a, an amazing way, it just...

it just warms me up inside.

Danny, look I know it's hard.

I miss her too,

we all do.

I just want you to know I'm here, if you ever need, you know, to talk.

I think the less said around this place, the better.

You never know when it could come back and bite you on the arse.

But we're nowhere near authenticating the facts.

It doesn't matter. We're releasing it this afternoon.

Ludicrous, irresponsible. Borderline criminal. Recent statements from Al Qaeda have referred

to them targeting infrastructure and financial damage rather than physical damage, haven't they? Yes, but...

The PM believes this to be an act of terrorism. Which it undoubtedly is.

We'd all be on safer ground if we acted more on evidence than beliefs.

Especially where others' lives are concerned, wouldn't you say?

I can see you'll be at the polling station bright and early.

I mean what's next? Are muggings to be brought under this mythical "terrorism" umbrella of yours?

People out there are scared enough.

There's no need to make their lives any more fearful.

And there's no point in pouring all our resources into waging

a war against terrorism when we can't point the finger at what it is we're fighting.

Look, think it through for a minute.

What if it's not them? What if it's some demented crackpot toiling away in a dingy basement in Coventry?

We look like mugs and you could alienate a lot of voters...

something which I know is dear to your heart.

You worry about finding these people, Harry, and leave the spin to us.

I've got three groups that have been very vocal in their criticism of Pharmavor and their whole Aids

drugs pricing policy thing and none of them seem to have any history of violent protest of any kind.

What about their employees?

No, I went over the Met's reports. No hits so far.

They don't have anyone there with so much as an unpaid parking ticket,

no-one with a Middle Eastern background, no messy layoffs...

No-one worth bumping off then.

Shame. Dig deeper.

I did find one thing, though. The signature on the note. Al Saa'iqa.

Thunderclap. Yeah, I ran it through our databases as well as GCHQ's.

It's the first time they've ever come up, there's never

even been any mention of them on any chatter or comms we've picked up.

Maybe it's a typo. Maybe they meant Thunderbirds.

Maybe one of the Tracy boys have gone bad. Danny, enough.

Go on. I did an online meta-search which also came up blank, but,

then I found something in an old book about the Crusades.

Now back in the twelfth century, they were a small group

of ruthless fighters, very devious, sort of like the Sultan's SAS.

The brains behind Al Saa'iqa was a brilliant war strategist called Ali Hassan Al-Mazboudi.

Now he made his name by taking the more advanced inventions of their enemies,

like the catapult for instance, and improving on them before turning back and using them to defeat them.

Bring your enemy down using his own technology.

Medicine. Exactly. This is going to get messy.

We're going to have to talk to the pharmaceuticals. Get them to put everything on hold.

Nothing can leave the factories without being double checked.

We may have to import drugs from abroad until we know what we're dealing with. Danny, pill factory.

Look do you want to talk about it?

Why is everyone so interested in my wellbeing all of a sudden?

I don't know. Could it have something to do with the fact that you've been acting like a total prat all week?

None of us wanted to lose Zoe, Danny. But that's the business we're in.

You want less pain, join an accountancy firm. Hey, don't knock accountants, all right?

My father was an accountant. Look, did you ever stop to think that...

Look let's just drop it, all right?

Forget the pep talk and let's just focus on the task at hand, you know,

defeating the forces of evil and all that.

Fine by me.

You've got to understand something.

We produce over seven million of those pills every year, we have done for over twenty years.

This couldn't have happened here at the factory.

What if someone tampered with them after they were shipped out?

The killer tablets come from different distributors in widespread locations.

It happened here. That's impossible.

This factory is as good as it gets.

The production is completely automated and computerized, it's monitored 24/7. No-one can tamper

with the process without being spotted, you need authorization codes and clearance levels...

The whole process is controlled by computers? Yes, of course.

This is The Control Room.

Colin. We're going to need you here.

This name they're using, Al Saa'iqa, it's very peculiar. It's not the kind of reference we've seen...

Not now, Ruth. We've just had two more deaths, in Portsmouth.

And it's not the same brand of pills.

Pharmavor's production line, the machines that actually combine

and compact the ingredients into tablet form, they're not online.

And no phone line means no way of hacking into them.

However, Adam's theory isn't entirely without merit.

Go on.

In most painkillers, the main ingredient is generic, something companies like Pharmavor

buy in from an outside supplier, in this case, one that also happens to be a major supplier of menazorphine.

And the supplier's machine is online and can be tampered with.

Yes. Whoever did this, simply messed around with the composition of one or two drums.

How stupid is that? Don't they have any firewalls on their system?

They do.

Sadly, their servers are a rather popular model of router which is still set to its default password.

You mean "Password".

And we're meant to protect these people?

Well, normally, I wouldn't complain, it's been a great help in letting us

into systems that we've wanted to sniff around in,

but in this case... rather more unfortunate.

OK, so what you're saying is this wasn't hugely difficult to do.

No. Intermediate to expert level hacker, but not rocket science.

Which should be good news, except that it widens our net.

Let's narrow it down some more. Can you track it?

Well, the IP address it came from hosts hundreds of different users.

Maybe this new attack will give us more data.

So we have a whole new gaggle of suspects. Fundamentalist hackers.

They want to drag us back a couple of thousand years, but they don't mind using technology to do it.

The reference to your chap.

Al-Mazboudi? It's not about using medicine as a weapon.

No. No, it's about turning every computer in the country into a potential killing machine.

All right, we need to look at all the hackers we know of. Any programmers who are capable of doing this.

Cross-reference for anything even remotely linking any of them to Islamist causes.

Check bank accounts, recent travel movements, chatrooms, the works.

And put out an urgent alert to any other morons out there to change their bloody passwords, will you?

Sure.

Oh! Well, this is turning into my lucky night. How'd you get in here? She gave these to me, remember.

Where is she, Danny? We've been through this. I can't tell you.

Well, I want to know. I deserve to know.

It's not my decision.

Oh, and I bet you're all broken up inside about that, aren't you? What's that supposed to mean?

Oh, come on. That whole brooding thing ever since her and I got together.

That's more than just a friend looking out for her, isn't it?

Where is she, Danny?

I'll say this slowly so you can understand, OK? I can't tell you.

Can't, or won't?

Look, it's not up to me, this thing is complicated enough without...

Forgive me for complicating the life of the almighty secret service, but this is my life we're talking about.

I'm not an idiot.

I read the papers. Agent X? Come on.

Zoe disappears the same time as an unnamed female MI5 agent is tried and sent away for ten years?

It was her, wasn't it?

I can't tell...

TEN BLOODY YEARS, DANNY!

Was it her?

Yes.

Where is she?

Just tell me what prison she's in. I just want to talk to her.

You need to leave.

Tell me where.

I can't talk to you about this, don't you understand? You have to go. I'll go to the press. I swear.

Fine. I'll tell them everything, everything I know. I don't care!

TEN YEARS!

Ten years. My Zoe...

Danny...

Just tell me what prison she's in. I only want to talk to her.

She's not in prison.

What?

She's not in prison. They fixed it.

I can't tell you any more than that. But... Just leave, will you?

Talk to them, Danny. Tell them they've got till tomorrow night to let me know where she is,

otherwise this thing hits the headlines.

Yes, I know, I know, I know.

I'm sure every parent is calling you about their child, but I just wanted to check.

'...Paracetamol while this matter is being investigated.'

Ok, very good, very good, thank you.

Wes all right? He's fine.

The headmistress has already told all the teachers and cleared any pills from the school's infirmary.

See? What? I just want to make sure our son was safe.

What's wrong with that?

I see you're bringing out the big guns.

Shock and awe. Works every time.

What is it this time? Spain?

Morocco? Hmm, not even close.

Yeah, but you're going to have a tan when you get back. Maybe.

Then again, even three stars in the Alps have indoor swimming pools.

Damn.

At least I'll be able to call you.

Late. How late?

How many time zones are we talking about?

Less than twenty.

You going to be back on Saturday?

Mmm.

I promised Wes we'd take him to the Science Museum.

And it's the last weekend of that Space Fair thing, he's dying to see it.

You might have to take him yourself.

We haven't done anything with him together for ages.

I'll try, I really will, but you know what it's like.

What?

Adam, he'll be fine.

It's not as though he's not used to it. I know, you know, but...

He's going to be eight in two months.

He's going to start asking questions about stuff.

About why we're never here. You mean why I'm never here. Well...

I miss him. I really do.

We chose this life. And what we do matters. Even to Wes.

I know, I know... I'm getting worrie about this new placement of yours. It's as though you like staying put.

No, I just like the idea of being there for him.

In the flesh, you know. At least he' got one of us looking out for him.

That's more than I ever had. Yeah and look how you turned out.

Well, come on what do you think?

Aren't you even curious to know what it would be like to actually live together, like a real family.

A real family... please.

My own son doesn't even know my real name.

Hardly anyone outside Damascus does. It's for your own protection.

And his. Fine but that's not what we were made for is it?

We need more than that, don't we?

Ruth, I tried to get money out this morning and the cash point wouldn't give me any,

it's saying my bank balance is zero which it definitely isn't for a change. You're not the only one.

'Panicked customers have flooded into branches of the bank

'after finding their balances wiped out.

'In Westminster this morning, Security and Intelligence Co-coordinator, Guy Facer.

'had this to say.'

I just want to reassure people out there that everyone's savings are

perfectly safe, nothing's been lost. It's only a temporary problem.

By law, every bank in this country has many safeguards and back-ups

to ensure that no data is ever permanently lost. They have hard drives that are...

He'd be more reassuring if he didn't look like he was enjoying it so much.

Another bank's just been hit. The word is spreading like wildfire,

the FTSE's already down over four hundred points.

This just came through.

Someone tell me their password wasn't set to 'password'.

Take away that which the infidels hold dearest, and watch as they turn on each other like rabid dogs.

They've got such a lovely turn of phrase, don't you think?

But they haven't made any demands.

Isn't it obvious? They want to bankrupt us.

They're doing a good job. About time we did ours.

Colin, tell me something uplifting.

Well, it's shaping up to be the driest autumn on record.

Do you want to be taken out and shot?

Well, I've got six teams here working on tracing the source of the hacking,

and the National High Tech Crime Unit's got all of their programmers working on it.

They're sending over a couple of their people to work from here.

Good. Whatever it takes. I want these techno freaks stopped.

Harry...

I need a minute.

Is he, um...? I don't know.

I think he'll do it. He'll be in breach of the Official Secrets Act.

He could go to prison. I don't think he cares.

He really wants to talk to Zoe.

Tell him to go ahead and do it.

He can hold a live press conference for all I care.

But tell him this -

if he does that, if he breaks this story,

then all he'll have done is make damn sure that Zoe goes to jail, because that's what would happen.

Is that what he wants? Why can't we just tell him where she is?

It's for her own safety, Danny. You can't rely on everyone's discretion.

You saw what his brother did. How many other dodgy friends and relatives has he got?

Who else won't jump at the chance to make a few quid when they find out?

And what happens when Will and Zoe break up? Can you guarantee he won't sell the story then?

I don't want her to go to prison, Danny.

And if that means she's got to find another boyfriend...

They were going to get married, Harry. She trusts him.

It's a human failing she'll have to overcome.

Andrew? What are you doing here?

Hey, Ruth. It's been ages.

Well, I wouldn't go that far. You two know each other?

Yeah I was toiling at GCHQ at the same time as Ruth.

Andrew and John are working with the National High Tech Crime Unit.

They're going to help liaise between Colin's teams and the NHTCU from here. Good.

This way.

Wait wait wait, go back, go back to this one.

Any luck tracing our hackers? This node here.

Look at the time delay.

It looks too close to be just...

Yes! See that?

That's also a Westar downlink.

Which could be...

Stop the presses.

He's routing through the same CMT host as the one from the second bank.

I'll come back later. Of course...

But it's not enough. We can't triangulate

without INTX signature packets from a secondary root server.

But we have one. The first attack, the one on the pill factory.

That's also on INTX. Of course.

We can triangulate back from there.

That should tell us where they're coming from.

We've got them.

Now our scans indicate high emission readings in this area here.

Which correlates with the wiring plans we found.

I'd say that's his computer room.

You sure about that? No.

He could be using a laptop with a wireless connection. He could be anywhere in there.

Great.

Well, we've got no choice. Danny, you and Alpha unit use this access here,

make sure this section's covered, I'll take Charlie unit and cover the main staircase.

All these years of massaging the hearts and minds with these people

and we're about to flush it all down the toilet. I can live with that.

Adam... I think you should see this.

A TV crew? What are they doing here?

Danny, call Harry. Find out what the hell is going on.

What are you doing?

Put that away. What do you think you're doing? Get back in the van and get out of here.

We got a tip off that the mosque was about to be raided. What part of get out of here don't you understand

Is it true the hacker attacks are the work of Islamic cyber-terrorists linked to Al Qaeda? Oh, no!

Is that what you're doing here?

We've been spotted. I repeat, we've been spotted. Keep rolling.

Tell him to abort and stand down.

I repeat, stand down.

We can't do anything with the entire bloody press out there.

Get me Guy Facer now.

Adam... Yeah? Harry wants us to stand down.

We can't do that. They'll wipe out all the evidence.

Screw it. Alpha One to all units. We are go, I repeat...

we are go. Seal all the entrances and somebody

get those reporters out of here! John go!

Stay where you are!

Danny, talk to me... Clear at my end.

Everyone up against the wall with your hands where I can see them. YOU. I said up against the wall NOW.

Hey! The man said up against the wall... do you speak English? Danny!

Stop it, you have no right... Danny! Don't talk to me about rights.

That's enough!

What's yours look like?

I've checked all the caches and so far nothing.

That was unnecessary. So you're squeamish now? The guy was resisting...

He wasn't resisting anything.

One more tap of that keyboard could have triggered another disaster.

Pulling him off his chair is one thing.

Using him as a human punch bag is something else.

What's your problem? We got them, didn't we?

Maybe.

Just go home and think about whether or not you really want to come in tomorrow.

I'll tell you what, Adam. I'll come in tomorrow, and the next day.

But as soon as this thing is over, I am out.

Fine by me!

But as long as we're doing this, I need to know I can count on you.

You don't have to worry about that. Good. Great.

Excuse me.

He's alive.

'Hi, and welcome to the party sex line.

'We have dozens of horny, filthy, dirty housewives...

'Women waiting to talk to you...'

TV: '...causing dozens of collisions, many of them serious.

'At least twenty-one people have been killed and many others critically wounded.

'Hospital officials have confirmed that the death toll would have been lower

'had the emergency services been able to reach the victims sooner,

'but all calls to 999 were routed to sex chat lines...

'while traffic across the city came to a standstill...'

It's staggering.

Nowhere's safe. And all it takes is one person,

someone with a computer and a phone line, doesn't it?

That's a reflection of our times. Everything's pushed to extremes, even that.

FAX MACHINE BEEPS

This isn't about Islamic fundamentalists.

Our hackers have set us up.

It isn't even political. It's just good old fashioned greed.

What is it?

We had a look at the traffic management centre's systems.

Now they've got level five firewalls, rotating SP lines, an RC5-128 cipher packet.

And everything is running the way it should.

There are no sniffers in there,

no back doors. But he still managed to get in.

I mean, we know this was an outsider attack.

Yes.

What are you saying?

I'm saying that there's only one way he could have got in.

The problem with making the internet a reality was always security.

Until you could be sure that no-one could intercept

an e-mail addressed to you or hack in and steal your credit card details, no-one was going to use it.

Then thirteen years ago, two techno freaks in Seattle, Gibson and Joukowsky...

G&J...

came up with something amazing.

An algorithm, a code, which has become the basis of virtually all internet electronic encryption.

The G&J algorithm.

Never heard of it.

Most people haven't. But every time you send an e-mail,

every time you buy a DVD online, you're using it and you don't even know it.

They've made millions from it. So you're saying whoever is doing this has cracked this code? Yes.

You've got to understand something.

We're talking about numbers that are two hundred digits long.

There are competitions with massive cash prizes for people to try and crack this thing.

Hundreds of thousands of dollars for whoever comes up with the key to decoding it.

But not a hundred million.

Maybe someone's decided to go for the jackpot.

We should look at anyone who's participated in these things.

We're getting the lists, but it's a big one.

All the best hackers and programmers from around the world take part in them.

But no-one's managed to do it.

No-one's even come close.

Whoever's behind this, whoever's got this key,

can go through any firewall and hack into any computer he likes.

Imagine what we could do with that.

Imagine what people like Guy Facer could do with it.

Right, I want a wide sweep.

Every programmer, every hacker we've been watching.

I want them dragged in, I want them throttled till they spit out a name.

That's a lot of people. The more, the merrier.

Guy, this is not about Islamic terrorism.

You know that and I know that, but we don't need to let everyone in our little secret just yet, do we?

Let the people out there have a good night's sleep, Harry.

I don't know what's more terrifying.

The idea that it's a group of deranged zealots trying to do this

to us, or the fact that it could just be one man and his laptop.

It doesn't matter much.

We're prepared to pay. But there is a caveat.

We want the G&J key.

You sure about this? Absolutely.

Look at this one. It's also slanted the wrong way.

Whoever wrote this doesn't really know how to write Arabic.

They're just copying it from a book. OK, stay on it.

What? You think I'm wasting my time?

Well, we already know he's faking it. So...

Have you ever read Flaubert?

No.

"God is in the details".

The answer's right there in front of us.

It always is. We just have to keep looking till we see it.

If you say so, Ruth.

Andrew.

Ruth. Tell me something.

When was the last time you went to a book shop?

Why? Humour me.

Well, I browse through one almost every day. Really? Which one?

The biggest one in the world. Online, of course.

Take me to your lair.

They want the G&J key. Why am I not surprised?

I'm sure they'll make a judicious use of it.

Cross-reference the search patterns for the historical background with book searches on Arabic writing.

See if we can find out where our pseudo-fundamentalist is getting all his nifty lines from. Not a problem.

I'm impressed.

Well, spend a few years sitting at a computer with

no-one around to distract you with the trivial things in life, you'd be surprised at what you can do.

Trivial things? Well, friendship. Family.

Open spaces, sunny skies.

You know... all the things we never have time for.

What about you?

How's life been treating you since GCHQ?

Ah, I suppose I have my health.

Oh, that good, huh?

Oh, come on. Look around you.

Could you possibly conceive of a better, fuller way to live one's life? Oh, yes.

So what's stopping you?

Probably the same thing that's stopping you. Fear of change.

Habit.

My cat.

Yeah, I shouldn't complain really.

I suppose I also have my health...

though I can't remember the last time I had a full medical.

I dread to think of what they might find. What's that?

No sign of life.

You should go home. Tomorrow's going to be a long day.

I'll be fine.

OK.

Look, I'm... I'm sorry.

You know, about before.

It's just I... I know.

It's OK.

Are you going to be all right?

The flat's so quiet.

She was going to be leaving soon anyway.

Yeah, I know, I know...

I suppose her being there all this time was just delaying the inevitable. She was in love, Danny.

But what you and Zoe shared...

It doesn't just disappear because there's an ocean, or another man between you.

You're lucky.

I don't feel lucky. You should.

A bond like that, knowing you can absolutely count on someone,

anytime, anywhere, to be there for you,

to do the right thing...

I envy that.

Don't you ever wonder...

about this path we've chosen?

Every night.

I think you need to brush up on a little concept called sleep.

Yeah, I vaguely recall the notion. Is it all it's cracked up to be? It's actually mandatory.

Check your user's manual.

Any hits yet? No, but there's always tomorrow.

Another day, another manhunt.

There's something else we can throw into the mix.

The more I think about this guy, about the choices he's made, the way his mind works...

he really likes his history, it's not just something he's casually picked up.

And I'm pretty sure it's not the first time he's used such references in his work.

He'll have used them before, references from the same period,

maybe even from Muslim history or literature.

Like the poetry he quoted in the faxes.

He loves this stuff.

We need to cross reference our search with user names, domain names, software titles.

The personal touch...

It's always hard to hide.

What do you think?

I think we should definitely look into that...

tomorrow. You're right.

I know it's late, but... have you had dinner yet?

Can't imagine who would feed us at this hour.

Well, if I may be so bold... I make a pretty decent carbonara.

Why not?

I'll find us a taxi. Meet you outside?

OK.

KNOCK AT DOOR

Come in.

Did you talk to them? Yeah.

And? No deal.

What? No, your...

They wouldn't risk it.

You really have no idea who you're dealing with.

Fine.

You had to sign a piece of paper after you started seeing Zoe.

Official Secrets Act.

Ring any bells? I don't care.

Look, just forget about her.

She's better off anyway... away from this insanity.

Is that what you're going to do, is it?

Just forget about her?

Look, you're just going to ruin your life. And hers.

Talk to the press and all you'll do is make sure Zoe spends the rest of her life in some grotty prison cell.

Is that what you want?

I wonder what gives you more pleasure?

Telling Zoe about those stolen photographs,

or watching me here like this?

Now, if you really loved her Danny, if you had any feelings for her, at all, you'd want her to be happy.

But that kind of selflessness is way beyond you people, isn't it?

You know I really don't know how you sleep at night.

Call sign, please.

Foxtrot Echo Lima 699. How should I direct your call?

Life Desk, please.

Adam? Is she OK?

She said that she wasn't going in deep this time and I haven't heard from for two days.

Has anything changed?

We've had a small problem.

She's had to go under.

Well, is she all right? Well, she isn't due to come up for air for another seventeen hours.

Well, let me know when you hear from her, all right?

Is anything wrong, Adam? No, no, no.

Just, just let me know, will you?

That was just heavenly, Andrew.

Thank you. It's a pleasure.

I have to say...

this house, perfect carbonara...

How is it you're still...

unattached? I could ask you the same thing.

You haven't tried my pasta.

Seriously.

How'd you end up at GCHQ?

Someone with your talent.

I've imagined you cruising to your third flotation by now.

Nah. Unfortunately, I suppose I'm, er...

I'm not enough of an entrepreneur.

Didn't have the killer instinct, you see.

Anyway, that's all in the past.

I prefer to look ahead.

I'm leaving the service.

Really?

Yeah, it's something I've thought a lot about,

and talking to you...

What... what are you going to do?

I don't know. See the world.

Find somewhere warm and slow.

Just enjoy my life, for a change. Sounds wonderful.

Yeah, the world... it's all about greed now, it's all about lies and spin and corruption...

I don't want to have to think about that any more.

Well, when you find the spot,

let me know.

"Ready am I to go,

"the sails of my eagerness await the wind..."

"And then I shall come to you, a boundless drop to a boundless ocean."

Don't you just love Abu Nuwwass?

I need to, er... Ruth.

Andrew, no! Please...

Why do you have to be so good at what you do, huh?

Anything? No.

Is Ruth not here yet?

No, I don't think she's coming in today. She texted me to say she was feeling horrible.

Well, drag her in even if she's got pneumonia. I want everyone here.

Get Colin in here now.

He's here. Online. Messaging me.

Can you trace him? Keep him talking.

What's going on? Take a look.

Colin? I'm working on it!

The bastard has a sense of humour.

Colin! Almost there!

He's nearby.

He's going to sign off... COLIN!

He signed off. Did you get him?

Yes. The messages were coming from Sam's computer.

He was using it as a slave.

I feel very Gollum-esque.

I don't know what to do about Ruth.

I sent a car around to her house but she's not there...

Are those the diamonds?

DON'T TOUCH THEM! Really, Malcolm.

I'm just looking. It's not that.

They've been tinkered with.

Genetically modified cobra venom.

Goes in through the skin. Kills in under one minute. Heart failure.

We've got to stop him in his tracks.

And there's Mr Frodo. And Sam.

Anything? No. Is everything in place? The car's tracking device is online, all Met squads within

a hundred mile radius on standby as well as two choppers ready for lift off.

We'll get him. Have you seen Ruth?

I don't know where she is.

She said she was sick, but... MOBILE RINGS

'Go up to the roof, alone. Now!

'You have one minute.'

He's given me a minute to get on to the roof alone.

I want all exits to the building sealed now.

Where's the back-up? Get the back-up generator on.

Can't. Everything's down.

It's a chopper.

They're using a helicopter.

It can't be. Radar hasn't picked up anything.

No, it's too small for a radar. It's a model. A remote controlled model.

MOBILE RINGS

Put the diamonds on the hook. And no tricks. I'm watching.

The helicopter's gone! It's taken the diamonds with it.

Joukowsky... "J"... We were at Cambridge together.

Him and Gibson... Their fabulous key...

It's all based on my work.

I practically invented it.

Only they were smarter. They took a patent out on it.

Me, I, I just...

I didn't think that far ahead.

I was just in it for the challenge.

Didn't they ever offer you anything in return?

Not so much as a mention in one of the hundred cover stories about them.

Nothing.

So what happens now?

Our munificent government wants to buy it from me.

For these.

And are you going to give it to them?

Oh, please. Something like this in their hands... no, I think it's something everyone should enjoy.

You're going to release it?

Why not?

You can't do that, Andrew. You can't release it.

It'll wreak havoc.

The internet, bank systems, the stock market, all compromised.

You'll devastate the markets, the economy...

The world will be a better place.

Bring things back to a saner level.

Andrew, listen to yourself. You can't really want this.

You'll ruin millions of lives.

So be it.

It'll be the great G&J legacy.

What better way for the world to remember them?

What am I going to do with you, Ruth?

A toy!

They've screwed us with a bloody toy! What are we dealing with here, a teenager?

They're hardly toys. We use them for surveillance in Afghanistan.

Well, they can't sell them in many shops. Can they? We're on it.

What do we do now? We wait.

And hope the venom does its trick.

It could be days before someone finds the body. Weeks even.

As long as those days are nice and quiet, I don't mind.

Let's hope he can't delete the G&J key before he snuffs it.

I'm sure Facer and his boffins will find a way to retrieve it.

I wouldn't entrust politicians with that much power.

The G&J key is dangerous.

They won't let a small detail like a delete button stand between them and their magical key.

Where's Ruth? Sick. Poor girl.

She couldn't even call in. What are you talking about?

She sent a text message. A text? Ruth? Are you sure?

She sent a text message to Sam.

What's so strange about that? Ruth doesn't even know how to change ring tones. Danny...

Come on Harry. When was the last time Ruth took a day off sick?

Who was the last person to see her last night?

I left around ten thirty, Ruth was still here. What was she working on?

She was profiling our hacker, trying to trace him by cross referencing

online search patterns and purchases. What if she got lucky?

What if she found him? Is there any way he could know Ruth was onto him?

Well, yes, with keystroke monitoring. But...

What if he's lifted her? He knew how to get onto your screen.

He had Adam's mobile number, he seems to know everything about what goes on in here.

Check the CCTV footage.

Finish what she was doing. If she spooked him, we can't be that far off.

Stop there, looks like Andrew was working late too.

Get onto him, see if he knows anything. I'm on it.

What are we missing?

Details. God is in the details.

Danny, we've been through this...

We're missing something, all right, otherwise she'd be here.

It's happening here.

The G&J key...

Gibson & Joukowsky are based in Seattle, but this isn't happening in America. Why?

Why only here? Let's pull up everything we know about these guys.

Have they ever lived here? Worked here?

Joukowsky spent a year as an Amherst scholar at Cambridge.

Cambridge. Lots of techno freaks there.

Maybe our guy and Joukowsky crossed paths.

Let's get into the university's database.

We need to know what courses he did, who his classmates were. Easy.

Forrestal. A Forrestal. Forrestal?

I've just spoken to the NHTCU. They haven't seen Andrew all day.

It's Andrew. He's got Ruth.

Ruth? Danny!

Ruth.

You OK? I knew you'd find me. I just knew it...

You OK?

We're fine.

Harry! Andrew's dead, Ruth's fine.

It's such a waste.

He could have done so much.

It's all right Ruth.

He was just so...

alone. It's all right. It's all over now.

Careful.

Promise me... you promise me that we'll never end up as broken...

or as bitter. I promise.

I promise, Ruth.

Yes, I understand.

OK.

Yeah, I'm listening, OK, yeah, yeah.

I'll be right back.

Looks like the G&J key will die with Andrew.

Will, it's Danny... we need to talk about Zoe.

And there's absolutely no sign of that program?

None whatsoever.

Pity.

'...Paracetamol is safe for use, it's finally being allowed back.'

Everything all right? Absolutely.

What's this?

What d'you think?

My officers tangled up in a sordid cocaine-fuelled fantasy of the sick and rich!

You've got to stop this! I can handle it!

I want my wife out of that house.

Riff! Someone's taken him!

I want to see him! I want to see my son!

The nation's awash with emotion over Riff and Bea's little baby. It must end well.
