08x05 - Sudden Death

[bunniefuu]

My boss. Samuel Walker.

Unidentified government
agents meeting in Switzerland.

Talk of a new world order.

Harry Pearce has come
to me asking for help.

Some talk of a global conspiracy.

You don't suspect Lucas?

I suspect everyone.

I have something for you. A covert
meeting in Basel, Switzerland.

Be careful who you trust.

I've asked Swiss immigration to
send photographs of all passengers
flying into Basel that week.

I should get the
information tonight.

If you want me to leave... Stay.

I love you so much.

OK?

I can't stop thinking
about Sam's girls.

They're too young to lose a father.

Did they have any idea,
about his illness?

Walker was a fighter, wasn't he?

Fought the odds every day of his
life. It seems odd that he'd
wave the white flag to cancer.

He didn't.

Sam wasn't sick.

We had him under
surveillance for months.

Ten days ago, we found the
smoking g*n, an account in
the Turks and Caicos Islands.

Eight deposits, over 50 grand
at a time. Who from?

The Chinese.

Dear God.

I was supposed to confront him.

Plan was a signed confession
for the archives, followed
by a dignified resignation.

So did he sign?

No, I never got that far. An hour
after I called to meet, he was dead.

He must have known we were on to him.

But it could have been handled
better. I should have handled it.

Listen, Walker made his own choices.

He knew the risks.

Then what the hell am I doing here?

Sorry.

This programme contains
some violent scenes

Yes! Whoo! Whoo!

Champ, champ, champ!

Home run.

Oh! Home run.
Next time, you're dead.

Any time, Mike.
You guys need the bathroom? No.

Double pistachio then, all round.
OK.

The American Embassy
is reeling today

after a memorial service for the
respected diplomat Samuel Walker,

whose career spanned
more than three decades.

Officials at the American
embassy paid tribute to
an outstanding public servant.

It's understood Mr Walker left
a suicide note referring to
a recently diagnosed cancer.


Walker was found, he
phoned me to arrange to meet.

Needless to say, he never made it.
Coincidence? Hardly.

We're leaving.
What? We haven't had our ice creams!

Go to the car, right now.

Hey! What's going on?

Get in!

TYRES SCREECH

CAR HORN BEEPS

Did Walker say what he wanted?
Just that it was about Basel

and went to the heart of the
intelligence services.

Less than an hour later he was dead.

Somebody wanted him silenced, Ruth.

HE COUGHS

Dad? Dad, are you OK?
Dad, what's wrong?

Dad, what's going on? Dad! Dad!

DOOR BUZZES

Got any coffee?

Still can't sleep?

What have you got?
Do you recognise this guy?

Should I? Michael Braydon, comms
expert, ex-Seals, ex-Special Service

and most recently on a covert
joint op with your friends at GCHQ.

Busy bee. Not any more.

He had a heart attack yesterday
after playing softball with his kids.

I'm sorry.

The Agency Fed-Exed his blood
samples back to the States.

Standard practice
in unexpected deaths.

The results came
back a half hour ago.

Turns out he had traces of
oxo-metacaline in his blood stream.

Now you know all about
that one, don't you, Lucas?

MI6's drug of choice when it comes
to promoting unhealthy hearts.

Sarah, you can't seriously
think it was Six...

They found a puncture mark
on Braydon's left thigh.

It was m*rder, no question.

One of our guys, in your city,
with MI6's fingerprints all over it.

Six aren't the only people to
use oxo-metacaline. Not any more.

Well, I sincerely hope not.

Why would they want him dead anyway?

Not everyone was a fan.
Braydon's remit was to look
at security breaches.

God knows what he found.

All right. Leave it with me.

Thanks.

Now, how about some breakfast?

I'm not hungry.

Sarah, I know how close
you were to... I'm fine, OK?

Just...

I'm sorry.

Just give me time.

DOOR CLOSES

'Is your Walker cover holding?'

Yes, so far. 'Keep it that way.

'We've got a long way to go
with this. No screw ups, OK?'

The American Ambassador's not happy,
Harry, and I can't say I blame him.

Two officers in less than a week.
What the hell is going on?

The honest answer? We don't know.

So far we've made no connection
between Walker and Braydon other
than they both worked for the CIA.

There is one other possibility.

Shortly before he was k*lled,
Walker called me.

Said he had more
on the Basel meeting.

Did he give specifics?
Unfortunately not.

You have to find out, Harry.

If this is connected to Basel,
I want it top priority.

Have you heard any more from your
contact? No, he was terrified
about telling me what he did.

Brief your team now.
If these two deaths have anything
to do with that meeting,

we may already be too late.

The Home Secretary has received
a warning from a highly-placed
source about a meeting in Basel.

Turns out officers from Western
and Chinese intelligence attended,

all off the record, all travelling
under assumed names. Their agenda,

to re-align the geopolitical map
once and for all.

So Darshavin was right?

Why wasn't I briefed about this?
Why did you keep it to yourself?

There was nothing substantive,
it was all rumour.

That's changed with Walker's death.

We need to find out what it was
he was about to tell me.

And why it was worth k*lling for...

twice.

What do we know about the
building where Walker died?

It was being used by the CIA
as an observation post.

When the Met attended, they found
all exits and entrances secure.

They impounded Walker's body so
fast, the Home Office pathologist
was still in his PJs. CCTV?

All feeds conveniently disabled.
Can we get feed from the vicinity?
Shouldn't be a problem.

Traffic in and out, one mile radius,
two hour window. What about Braydon?

He was working with GCHQ on
a suspected security breach and the
CIA are pointing the finger at us.

Six wouldn't use oxo-metacaline,
not now it can be traced.

Assuming it was ever actually in
his body. You think Sarah's lying?

It wouldn't be the first time the
CIA have falsified blood tests.

Sarah could just have
been the messenger.

In which case this whole thing could
go a whole lot higher, and deeper.

PHONE RINGS

Yes? 'Still saving the free world?'

Who is this? 'Coleville.'

Jack Coleville. My God.

How are you? I have something
I think you'll find interesting.

'The old place? Half an hour.'
Jack, I...

Thanks for coming, Ros.
You knew I'd come, Jack.

Are you OK?

Just tired.

Enjoying retirement? No.

You still love the job? No regrets?

Nothing the occasional
vodka can't sort.

I've missed you, Ros.

Did I do right by you?

Getting you involved?
I worry about that sometimes.

No, I wouldn't have it any
other way. You mean that?

No husband? Family?

You said you had something for me?

Always the professional.

You know how it is, Jack.

You're not serious?

Your memoirs?
Just the first few chapters. Why?

When one gets to a certain age,
one thinks of posterity.

You know the scrutiny committee
will never allow this through?

Plenty of foreign publishers
out there.

Yeah. Just don't expect your driving
licence to work, or your passport,
or your credit card.

You know the Service, Jack,
they don't like bright
lights in dark places.

I need to get them published, Ros.

They're all I have left.

I dabbled in some investments,
got out of my depth.
I've been very foolish.

But this... My past is the
only asset they couldn't take.

Please. Read them.

Then give me a call and tell me
what I can get away with.

OK.

I'm flattered. I knew you'd help.

MOBILE PHONE BEEPS

Sorry. Of course, of course.

Oh, you may find chapter three
of particular interest.

It's all about Harry...

and Gibraltar.

Good to see you, Jack.

Her story adds up. Sarah phoned
Walker to arrange a meeting, he got
scared, realised the game was up.

Why didn't she tell us earlier?
No-one likes washing their
dirty linen in public.

Walker was very dirty. For which we
only have Sarah's word. Sorry.

I suppose what it comes down to is
whether we think Walker was the type.

You knew him, Harry.

Walker was a political operator, but
he's also an old-fashioned patriot,
with an old-fashioned sense of duty.

I can't see him selling out
to the Chinese.

If the suicide's a smokescreen, it
brings Braydon back into the frame.

If Braydon had found a serious
lapse of security, the first
person he'd tell would be Walker.

He'd take a steer from him
before sharing anything with GCHQ.

Braydon gives intel to Walker,
Walker contacts Harry.

And someone feels so threatened
they give him the push, literally.

We need to focus on
the big question.

How deep inside the
CIA does this go?

We need to find out what
went on inside that building.

'The swipe reader is straight ahead.'

Got a package for you, mate.
Place is closed.

Can you sign for it?

No. No packages.
Got to deliver it, mate.

Like I said...
Yeah, yeah, I get the message.

Just gotta make a call.

Mel, I'm at the
Gordon Street drop off.

I've got a jobsworth who won't sign.

Contact made. Starting download.

Dispatch wants to talk to you.
This is City Fast Couriers,

you got a problem with the package
we are trying to deliver to you?

I'm not authorised
to take any packages.

What none at all?
No packages? Not a single package?

None at all.

What am I meant to do with it,
I don't want to bring it back here.

It's not a discussion, OK?
No packages, period.
You're not being very helpful.

It's bloody rude. All I want to do
is deliver a package.

That language is not necessary,
ma'am, you have a good day.

Yeah, you too.

Yeah, what do you want me to do?
Come on.



Er, 20 minutes?
Traffic's not too bad today.

Transfer complete. Bring her home.

On my way.

Thanks a lot, mate. Really helpful.

I pulled details of Walker's mobile
calls 72 hours before he died.

It's nothing out of the ordinary.
His family, the office, one to his
bank, pretty much what you'd expect.

Maybe even too much what
you'd expect. A dummy phone?

His records were surprisingly
easy to access. Any trace of any
other mobiles he may have used?

Not that I could find. And he chose
to use a payphone to call you, which
suggests he didn't trust his mobile.

So maybe it was his real phone.

Cross reference with
numbers he called, see how
far back we can trace it.

Your message said you had something?
More what we haven't got.

The package at the CIA did the
trick... We downloaded data from
the card swipe for the last 14 days,

then bracketed either side of
Walker's death. Nobody in,
nobody out.

So no-one was with him.
He did commit suicide.
He wasn't there either.

According to the database,
no-one went in or out,
not even Walker himself.

We know Walker called Harry
from a payphone near the
Hammersmith flyover at 6.43.

But after that, there's no
record of him swiping back in.

Which means he wasn't in the
building where he k*lled himself.
Kind of existential, isn't it?

So what's the deal?

Somebody wiped the data.

See all those zeros?
That's the intel we wanted.

There's nothing in a 20-minute
window either side of Walker's death.

Professional job?
It looks like it was done in a hurry

Harry, I saw Jack Coleville
this morning.

THE Jack Coleville? How is he?

He didn't look well.
Oh, I'm sorry to hear that.

Never understood why Jack opted out.

We all assumed he'd end up
running the Service.

He told me to ask you
about Gibraltar.

Gibraltar? Never been there.

Really? Really. Give him my best
if you see him again.

MOBILE PHONE RINGS

Yep? What do you think, literary
masterpiece? Shoe-in for the Booker?

Jack, I am so sorry, I've only had
a chance just to flick through it.

Bit of a shocker about
Gibraltar, don't you think?

Should get some media interest.
You got it wrong, Jack.

Harry was never there. You mean
when you asked him, he denied it.

Yes.
Remember interrogation training?

Of course. My little aphorism.

"There is no art to find the
mind's construction in the face."
You know how the rest goes.

"He was a gentleman on whom I built
an absolute trust." Macbeth.

I was there, Ros. I saw what he did
with my own eyes. Check the records.

Harry Pearce, Gibraltar, 1983.
You'll see.

That's three dead officers in a week
and the latest is one of ours.

Alex Winchcombe, born 1957,
BA and PhD in Modern Languages.

MoD for eight years, three seconded
to the US Army in the early '90s.

Joined us from GCHQ in '95,
as an expert in Balkan dialects.

He's been on the
fourth floor ever since.

Apparently, he's one of only
two experts in his field.

Was.

How did the police
know he was one of ours?

Someone left a helpful note.

It's a full CV.
Complete with details of every
operation he worked on.

Half this stuff's classified.
He was in Gibraltar?

Yes, he was stationed there for
a couple of years. '83 to '85.

Walker, Braydon, Winchcombe.
Is there a connection?

Get a full breakdown of all
Winchcombe's postings and liaison
officers, including the Americans.

Specifically Samuel Walker
and Michael Braydon.

Ruth, dig up the personal -
relationships, finance,
recent trips abroad, usual stuff.

And get a printout of all
Winchcombe's calls over
the last couple of months.

Whoever compiled this had
full security clearance.

If they can get this level
of detail, what else
have they got access to?

Just about every asset we have.

Contact all serving officers,
increase alert levels across
the board. That includes us.

With this kind of access,
we're all at risk.

We need to stop this before any
more MI5 officers are k*lled.

As I thought, pure fiction.

No element of truth?

Ros, do you really imagine I
m*rder*d an innocent civilian
during interrogation? No.

Thank you. So why write it?

Jack knew it would take me about
five minutes to check the system.

There were rumours after
he left, of a breakdown.
He seemed perfectly rational.

And desperate for cash.
Sensational stories sell and are
almost impossible to disprove.

Of course. I'm sorry, Ros.

I know how important he was to you.

He was a fine officer.

Oh, my God.

Jack.

There must be something, Tariq.

There's something here all right.

Combo Bluetooth/Wi-Fi chip.

It intercepts local Bluetooth traffic
and re-transmits it via
a short-range network.

So it's data, not audio? Yeah. It's
designed to capture keystrokes from
wireless keyboards then pass them on

There should be a relay somewhere
outside the building hooked up to
a mobile.

From there you could send the
information anywhere in the world.

So Coleville could have a record
of every single keystroke I've made?

Yeah. It's a pretty
neat piece of kit.

He knew I'd check
his accusations against your
record and once I did...

He got a copy of your password.
What's the damage?

Can't be sure until I run
a full history check.

We know Coleville accessed
all of Winchcombe's records.

But he didn't give Ros
the folder until after Walker
and Braydon's death,

which suggests he already knew
enough about them. Why would he
take out one of his own?

He was fiercely loyal. He lived and
breathed the Service his whole life.

It just doesn't add up.

What are our options
on data security?

I can do an emergency reset.
Shut the system down,
block all known passwords.

If he tries again and he's locked
out, he'll vanish. But if we don't,
he can access whatever he likes.

I could set up a mirror site
with a time lapse, give us a time
to react if he tries again.

How long would that take?
A bare bones copy, maybe an hour.

Do it.
How does Coleville make contact?

Phone, never the same number twice.
We have to find him.

We have to go through
everything we have on him.

If Coleville tries to access the
database again, can you monitor
what it is he's looking at?

Shouldn't be a problem.
Call me the second he tries.

If he gets too close to classified
files, pull the plug. Shut him out.

Coleville's chip,
is it still transmitting?

I deactivated the battery until
the mirror site's up and running.

Turn it back on.
Isn't that a bit risky?

The Bluetooth hooks up
to a mobile, right? Yeah.

Which then calls another mobile.

Which we can triangulate,

as soon as the call goes through,
and find Coleville. Smart boy.

We've got an address for Jack.
Get on to CO19.

No, Harry, we don't know for sure.
Ros, how much more do you need?

Let me talk to him...please.

I need to find out
why he's doing this.

Take Lucas. And, Ros,
no heroics. Yeah.

The place is empty, Lucas.

Apart from a copy of Macbeth.

Coleville's favourite play.

Claimed it told you
everything you needed to know
about the rise of evil.

He knew you were coming.

Yeah. One step ahead, as ever.

HIGH-PITCHED BEEP

PHONE RINGS

Yes? 'You all right?'

No! I am not bloody all right!

You shouldn't have broken in, Ros.
An Englishman's home and all that.

Jack. You could have k*lled me.

But I didn't, did I?
I knew you'd be fine.

No, no,
you couldn't have known that.

I taught you, remember?
I know how you think, Ros.

I know everything you're
going to do before you do it.

Jack, what is this about?
What are you trying to achieve?

I'm glad you're safe.

Jack Coleville was one of the
finest officers Six has ever had.

Specialising in covert operations
in pretty much every theatre we've
operated in over the last 25 years.

Smart, courageous, innovative.

The complete package.
He's also the reason I'm here.

He recruited me.

Does Coleville have any association
with Walker?

There's nothing definite.
The only thing linking our victims
so far is an Operation Acorn.

A joint UK/US covert operation in
the Balkans. Shut down in the '90s.

Work on it. Get a full
list of personnel from Six.

Lucas, liaise with Sarah, see
what she can give us from her end.

List of officers involved,
nature of missions,
any unforeseen consequences.

Coleville's accessing the database.

We've got a 20 second
real time lapse.

Want me to close him down?
We'll lose Coleville if you do.

Let him run with it.
He's downloading a file.

He's got it.

What's Roger Maynard to Coleville?

Unless we get to him first,
a dead man walking.

Find him. Throw everything at it.
And pull Sarah Caulfield in.

We need all the help we can get.

We've got a lead on who
k*lled Braydon. And Walker.

So it wasn't suicide?
It doesn't look like it.

Who is he? We think he's responsible
for another m*rder, on our side.

Was I right? Is it Six?

Ex. Jack Coleville.

Coleville? Are you sure?

I thought he retired years ago.

Yeah, so did we.

Lucas, is there something that
I should know? Like is this
another mega Brit screw up?

We need to find Coleville and we'd
appreciate any help you can offer.

What do you need?

For a start, we need
a trace on everyone involved

in a joint UK/US operation,
codenamed Acorn, '91 to '95.

Any personnel still in the UK
need full protection as of now.

How much worse is this going to get?
I don't know.

For what it's worth,
we think his next target is one of
our ex-officers, Roger Maynard.

Lucas.

Sam Walker was a friend.

If you find Coleville...
You'll be the first to know.

Yeah, we just got lucky.

Get me everything you can
on Roger Maynard. 'Sure. Why?'

Because Jack Coleville wants him.

And I need to get to
Coleville before MI5 do.

GATE BUZZES

Yes.

It's Maynard. Ros. Got him.
Where? Right here.

'So far Vladic is refusing to even
acknowledge the International Court
of Human Rights,

'but this doesn't mean
he can't be convicted.
The evidence...'

We have to get there
before Coleville.

Lucas is in the field.
Get him over there now.

And contact Maynard,
give him a liaison point.

Just make the call.

Would you like directions? No.

OK, I'm in.

On my way.

INTERVIEWER: What are the wider
implications of this trial?

MAYNARD: It could prove
embarrassing to the West.

They certainly used
Vladic when it suited them.

He could implicate
several intelligence services,
including our own.

'Maynard's still in the studio,
third floor.'

Thanks, Roger.

MOBILE PHONE VIBRATES

Maynard. Code 378.

Confirmed. Exit 19. Repeat Exit 19.

Copy. Exit 19.

'Intercept from MI5. Target to

'Contact made. Exit 19,

LUCAS: Copy that.

INTERVIEWER: I need
Maynard back here now.

LUCAS: Exit 19, no sign of Maynard.
TARIQ: He's on his way.

I'll intercept.

Roger Maynard? Sarah Caulfield,
Section D.

I'm here to escort you to Exit 19.
This way, please.

Stop. What?

Change of plan. We're to wait. Wait?

It's not safe to proceed.
Our instructions are to wait here.

This is crazy, we're sitting ducks!

You'll be safe, Roger. Stay here.

Tariq, something's wrong.
He's not here. Make contact again.
I'm gonna go look for him.

MOBILE PHONE VIBRATES

Maynard. Where are you?
Your contact is at exit 19.

I was told there was a change of
plan. Are you with Lucas North?

DOOR OPENS

g*n SHOT

Hold it right there.
Don't think I'd hesitate.

Drop it.

Kick it.

Hands where I can see them.

You're making a mistake.
I doubt it.

CIA? Shut up. I have no argument
with you. Nor me, you.

Unlucky, I guess. You just happen to
be my get out of jail free card.

Sarah!

g*n SHOT

Tariq, ambulance,
we're on the third floor!

I tried to stop him.

You're OK, Roger,
you're gonna be fine.
There's an ambulance on the way.

Look at me, look at me.

Do you recognise the
man who did this to you?

His name's Jack Coleville,
he was with MI6.

How do you know him, Roger?
Look at me, stay with me.

I need to know why
Coleville targeted you.

Baranova.

Mina Baranova.
Who is she? Is she Russian?

Come on, Roger, fight it. Fight it!

Coleville got away.
'That's unfortunate, Sarah.

'You better rethink
your Walker cover.'

I'll deal with it.

I think Maynard made it up.
Nothing's coming up
on Mina Baranova.

I've tried alternative spellings,
Cyrillic, Arabic and Hebrew
alphabets. All drawing a blank.

I've got a Mitko Baranov.
Serbian militia.

He's at the International
Court of Human Rights.

w*r crimes? As a witness.

Get a full transcript of his
evidence. Sarah Caulfield
checked out Braydon's records.

He was in Bosnia in the '90s
when he was with Special Services.

What are we missing?
What's the connection?

OK. We know Coleville and Braydon
were in Bosnia in the early '90s.

Winchcombe was an expert
on Serbo-Croatian dialects,

but there's no record of him
having met either of them.

Which leaves Maynard,
the most recent victim, he used to
be MI6 station head in Belgrade,

but not until 13 years later,
that's long after the others left.

What about Walker? His only
connection's through Braydon.

He was never posted to the Balkans.
He only met Braydon in Washington.

Which brings us back to
Mina Baranova.

Who doesn't seem to exist.

Maynard could have got her name
wrong. Or given us a false one.

Maybe there's no pattern, maybe
we just want there to be one.

We've circulated Coleville's details
to every major police force -
Interpol, FBI.

All serving and recently
retired officers are
already put on alert.

It won't be enough.

And the alternative?
We can't pull everyone in,

it'll cr*pple the service.
Which is what Coleville wants.

Jack Coleville is murdering
our intelligence officers.

We'll have to shut the system down.

We can't allow him access to any
more files. I've got something
on Mitko Baranov, he had a sister.

Mina? It's buried in his evidence
to the International Court.

Where is she now? In his evidence,
he says she died at the hands
of Muslim extremists.

But I can't find any other reference
to her. She has no medical records,

bank accounts, passport application,
nothing. It's like she never existed.

Maybe that's exactly
how they want it to look.

The Shadow Protection Programme.

Created by Six during the
Balkans crisis to protect sources.

Informers were offered
new identities, new life abroad.

Their past lives
completely obliterated.

Can we get access to those files?

We'll have to.

Coleville was
Mina Baranova's case officer.
He was running her as an informer.

She must have been compromised.
He arranged a new life for her.

Until five years ago, she was
in Greece, place called Skourta.

Then? File closed.
"Participant Deceased."

Who was the last officer to make
an entry? Maynard. Roger Maynard.

Search for Winchcombe.

He was her translator.

He's getting revenge.

Coleville's getting revenge.

It's Coleville,
he's trying to access the system.

We have to let him back in.
And risk another officer's life?

We have to, Harry. It's the only
way we can find out what he's after.

The moment I say,
be ready to cut him off.

He's drilling down.
He's accessing Mina's file.

He's after someone called
the signature officer.

That's the lead officer on her case.
Change the name to mine.

What? You've got 20 seconds,
Tariq, just do it!

Ros, it's too dangerous.
Tariq, just do it!

He may not come after you.
This could all be for nothing.

In all other cases, he k*lled within
hours of accessing their files.

This time it won't be any different.

Either in the street, in my flat...

He won't wait till tomorrow.

You don't have to do this, Ros.
I know. I mean it.

I want to, Harry.

I need to.

Approaching now. Home sweet home.
Check. Flat's clear.

Hope they've polished the floor.

Alpha team, stand by.
Visual on Lima One.

Alpha Four update.
Lima One, approaching property now.

MOBILE PHONE RINGS

Get a trace of the caller.
It's not her phone.

Yes. 'Hello, Ros.'

What the hell are
you playing at, Jack?

Where's he calling from?

I've always respected you, Ros.

Can we meet somewhere and talk?

I think it's a little bit
late for that, don't you? No.

I never think it's too late to talk.

'In that case you'd
better come and find me.'

Goodbye, Ros.

I thought this place was clean?

It was. Well, how the hell
did he get a phone in here?

Did you get a trace?
Not possible. He used a Skype
account registered in Croatia.

'Routed it through an off-the-shelf
pay-as-you-go. He's good.'

'He's nearby, Harry, I can feel it.'

Get out of there, Ros. No.

The place has been compromised.
Get out of the building now.

Don't you think he would
have known that, Harry?

We have to see this through.

I need to talk to him.

Harry?

Five minutes and
I'm pulling you out.

Any news? Still no sign of him.

'Ros is on the move.'

It's over, Jack!

Contact made. Stand by, everyone.

METAL CLINKING

Ros?

Put the g*n down, Ros.
Hands where I can see them.

I'm too old for this kind of thing.

Why?

I think you owe me more than that.

I don't know what to say, Ros.

Try the truth.

If anyone deserves the truth,
it's you.

I realise that. It's not easy.

Ros?

I don't know myself half the time.
It's all such a mess.

g*n SHOT

OK, move. All units, go, go, go!

GLASS SHATTERING

'Lucas, I've lost Ros' comms.'

Ros, where are you? Ros?

'Ros' comms are still down, Lucas,
I'm working on it.'

Still no answer. Keep trying her.

Lucas, I want to know the moment
you see her. Right now, Jack
Coleville is capable of anything.

She could be anywhere.

'Keep looking, Lucas.'

DISTANT BANG

g*n CLICKS

Just give me the g*n, Ros.

Now just keep going. Don't look back.

LIGHT SWITCH CLICKS

Thinking of calling the cavalry?

I wouldn't bother.
No-one can reach us here.

Why, Jack?

Why did you do it?
Someone had to pay.

For what?

Mina.

Do you remember her? Mina Baranova.

You signed her death warrant.

I don't know what you're
talking about. Please.

When you wanted to turn
Mitko Baranov, he had a price -

the whereabouts of his sister,
the "informer".

And you gave it to him,

without blinking an eyelid.

What was she to you, Jack?

Everything.
You were in love with her?

Not very professional, was it?

But we were careful. And it worked.

Until Braydon wanted some
scrap of information from
her sh*t of a brother.

So he told him that his sister
was seeing a British
intelligence officer,

purely for operational reasons,
you understand.

But she got a new identity.

Sure. New name, new papers,
different country.

Even I didn't know where she was.

But it was the price for her safety.

We would be apart,
but she would be safe, forever.

That was the promise.

And you broke it.

There was a w*r on, Jack.

Not when they caught up with Mitko.
It was all over then.

Do you know what he did?

He burnt a lorry-load
of Muslims to death.

They wanted him on
trial for w*r crimes.

And then some smart young officer in
London realised that maybe there are

bigger fish to fry, maybe Mitko
could be persuaded to testify.

Mina was Mitko's price.

But of course a decision like that
had to be referred up.

Someone in London had
to sign the death warrant.

Yes.

It didn't take them long
to find Mina.

A little help from the Belgrade
office and Mitko was on his way.

Do you want to see what
your signature did, Ros?

He didn't k*ll her immediately,
as you can see.

Reap as you sow, Ros,

reap as you sow.

Tell me,

did you know about Mina and me
and just decide to do it anyway?

Or was it just another name,

another anonymous victim,
signed to oblivion from your
air-conditioned office?

I didn't sign anything.

Please, not the denial.
I expected more of you, really.

When we found the chip,

we inserted my name on the database.

You have the wrong person, Jack.

That's not possible.

Who did it?
Who signed the authorisation? Does
it make a difference who did it?

It makes a difference to me!

I don't know who signed it.

The officer who happened to be
on duty on that desk that day.

It could've been me
or anyone, even you. No, no...
We'd have all done the same.

No, no, no, no.

It was the right thing to do.

The intelligence that Mitko
gave was invaluable.

The information...

put away not only the guilty,

but it saved lives, Jack.

Hundreds of lives. And that
makes it OK to sacrifice Mina?

Yes. Yes, it does.

You want revenge?
You go ahead and take it.

Maybe I deserve it, if not for this
then for the other decisions

I've made where innocent people
have got hurt.

That's what the job's about, Jack.

Don't make a decision
you can't live with.

That's what you taught me.

There has to be a reckoning.

Goodbye, Ros.

There's something
you need to know, Lucas.

You shouldn't be here. Why not?

Go home. Get some rest.
That's the last place I want to be.

What's up?

Ruth's been going through
Walker's phone records.

Erm, I wasn't getting
anything useful.

So I requested records from
the nearest relay tower to the
building where Walker died.

I got a full list of
mobile phones active in the same cell
around the time of his death.

And?

One of them was Sarah Caulfield's.

She was in the building
where Walker died...

when he died.

Are you sure about this?

Sarah was no more than
five metres away when he fell.

Lucas, she may not be responsible.

There could be any number
of reasons why she was there.

There's only one way
to find out for sure.

I think I'm beginning to get the
hang of the special relationship.

Yeah, I'd say you were
getting there.

I'm sorry I've been so...

..you know.

Walker's death...

threw me.

I understand. Do you?

It can't have been easy for you.

No.

Being close to someone,

finding out they're not
who you thought they were.

It's painful.

I'm just glad you got the guy
who k*lled him. We didn't.

Coleville didn't k*ll Walker.

He told Ros before he died.

It was my fault, then.

When I called Sam to meet...
he fobbed me off,

told me he'd come
by the office later.

I just stayed home all night.

He must have known we were on
to him, that's why he jumped.

I should've insisted, I should've
gone to see him right then.

I could have stopped him.

Maybe if I...had been there,
he'd still be alive. It's OK.

It's over now.

We can't change the past.

'You're sure about this?'
She lied, plain and simple.

Sarah k*lled Walker.

Yeah.

Yeah, I think she did.

We've run out of other explanations.

OK, well then I suppose
the question is,

was she working for the Agency
or had she gone freelance?

I really don't know.

'Then I suggest we find out.'

Why did you k*ll your boss?

We know you threw him from
the seventh floor balcony.

The country's on the brink.
We've borrowed, we've issued gilts.

The UK is bankrupt until


So we need the bank's money.

What I have is clear evidence
of tax evasion in the billions!

What do you think
they're going to want to do to you,

when they discover that you
have been recording their names?

I'm going to do a deal. They're not!
They're not going to let you walk!

g*nf*re

This is bad, Lucas.
These guys are not going to stop.

My life is over now. Baisley! Duck!
