Original subtitles

You okay?

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?

He fought the odds everyday of his life.

It seems odd that he'd waved the white flag to cancer.

He didn't.

Sam wasn't sick.

We had him under surveillance for months.

10 days ago, we found the smoking gun

and 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 to sign 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're onto him,

but it could have been handled better.

I should handled it.

Listen, Walker made his own choices.

He knew the risks.

What the hell am I doing here?

Sorry.

Champ, champ, champ, champ.

Homer.

- Oh. - Homer.

Next time you're dead.

Anytime, Mike.

You guys need the bathroom?

No.

Double pistachio then all around.

Okay.

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 pay tribute

to an outstanding public servant.

It's understood Mr. Walker left a suicide note

referring to a recently diagnosed cancer.

40 minutes before Samuel Walker was found,

he phoned me to arrange to meet.

Needless to say, he never made it.

Coincidence?

Hardly.

Come on, pass it!

Quick! Pass it!

- Leave it. - What?

We haven't had our ice cream.

Go in the car right now!

Go!

Get in.

Dad?

Dad, are you okay?

Dad, what's wrong?

What's going on? Dad!

- Dad! - Dad!

Got any coffee?

Still can't sleep?

What have you got?

Do you recognize this guy?

Should I?

Michael Braden, comms expert, ex Seals,

ex special services, and most recently,

on a covert joint op with your friends at GCHQ.

Busy bee.

Not anymore.

He had a heart attack yesterday

after playing softball with his kids.

I'm sorry.

The agency FedExed his blood samples back to the States.

Standard practice in unexpected deaths.

The results came back half hour ago.

Turns out he had traces of oxometacaline in his bloodstream.

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's Six.

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

It was murder. No question.

One of our guys in your city.

MI6's fingerprints all over it.

Six aren't the only people to use

Oxometacaline, not anymore.

I sincerely hope not.

Why would they want him dead anyway?

Well, not everyone was a fan.

Braden'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-

I'm fine, okay?

Just...

I'm sorry.

Just give me time.

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 Braden

other than they both worked for the CIA.

There is one other possibility.

Shortly before he was killed, 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 anymore 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 traveling under assumed names.

Their agenda, to realign the geopolitical map

once and for all.

So De Chauvin was right.

Why wasn't I briefed about this?

Why did you keep it to yourself?

There was nothing substantive, it was all rumor.

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 killing 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 Braden?

He was working with GCHQ on a suspected security breach,

and the CIA are pointing the finger at us.

Six used oxymetacaline knowing how it can be traced.

Assuming of course it was ever actually in his body.

You think Sarah's lying?

Well, it wouldn't be the first time

the CIA falsified blood tests.

Sarah could just have been the messenger,

in which case this whole thing

could go whole lot higher and deeper.

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. - Jack, I-

Thanks for coming, Ros.

You knew I'd come, Jack.

You okay?

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 a 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 license 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 and gimme a call,

and tell me what I can get away with.

Okay.

I'm flattered.

I knew you'd help.

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, realized 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.

Well, if the suicide's a smoke screen,

it brings Braden back into the frame.

So Braden finds 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.

Braden gives intel to Walker, Walker contacts Harry,

and if 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's straight ahead.

Got a package for you, mate.

Place is closed.

Can you sign for it?

Nah, no packages.

Gotta deliver, mate.

Like I said.

Yeah, yeah, I got the message.

Just gotta make a call.

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

I've got a jobsworth won't sign.

Contact made.

Starting download.

Spouse wants to talk to you.

This is City Fast Couriers.

You've got a problem with the package

we're trying to deliver to you?

I'm not authorized to take any packages.

None at all?

No packages, not a single package?

None at all.

Well, what am I meant to do with it?

I don't wanna bring it back here.

It's not a discussion, okay?

No packages. Period.

Well, you're not being very helpful.

I think it's bloody rude, actually.

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.

80%.

20 minutes, traffic's not too bad today.

Transfer complete.

Bring it 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,

and pretty much what you'd expect.

I mean, maybe even too much what you'd expect.

Dummy phone?

But his records were surprisingly easy to access.

Any trace of any other mobiles he may have used?

No, 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 it 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 building did the trick.

We downloaded data from the card swipe

for the last 14 days,

and 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 killed 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.

Fresh (indistinct)?

It looks like it was done in 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.

Yep.

What do you think, literary masterpiece?

Shoo-in for the Booker?

Jack, I'm 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, Braden, 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 Braden.

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?

Contact all serving officers.

Increase alert levels across the board, that includes us.

This kind of access, we're all at risk.

We need to stop this

before any more MI5 officers are killed.

As I thought, pure fiction.

No element of truth?

Ros, do you really imagine I murdered

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 rumors 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 wifi chip

to intercept local Bluetooth traffic

and retransmit 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.

Coleville could have a record

of every single keystroke I've made.

Yeah, it's a pretty neat piece of kit.

He knew I checked 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 Winchcombe's records

in their entirety, but he didn't give Ros the folder

until after Walker and Braden'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 the system locks him out,

he'll vanish.

But if we don't lock him out,

he can access whatever he likes.

I could set up a mirror site with a time lapse.

Give us 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 CO 19.

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.

Place is empty, Lucas.

Apart from a copy of Macbeth, Coleville's favorite 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.

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've killed 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 gonna 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, specializing in covert operations

in pretty much every theater 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 victim 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.

Who's Rodger Maynard to Coleville?

Unless we get 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 killed Braden and Walker.

So it wasn't suicide?

Doesn't look like it.

Who is he?

We think he's responsible for another murder on our side.

Was I right? Is it Six?

Ex. Jack Coleville.

Coleville? You sure?

I thought he retired years ago.

Yeah, so did we.

Lucas, is there something 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 gonna get?

I don't know.

For what it's worth, we think his next target

is one of our ex-officers, Rodger Maynard.

Yeah, we just got lucky.

Get me everything you can on Rodger Maynard.

Sure. Why?

Because Jack Coleville wants him,

and I need to get to Coleville before MI5 do.

Yes.

It's Maynard.

Ros, got him.

Where?

Right here.

So far, Vladich is refusing to even acknowledge

the International Court of Human Rights,

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

The evidence against him.

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?

Nope.

Okay, I'm in.

On my way.

What are the wider implications

of this trial?

Well, this trial could also prove

embarrassing to the West.

They certainly used Vladich when it suited them.

If he chose to, he could implicate

several intelligence services, including our own.

Maynard's still in the studio, third floor.

Maynard Code 378.

Confirmed. Exit 19.

Repeat, exit 19.

Copy, exit 19.

Intercept from MI5, target to exit 19.

Check back route.

Okay.

Contact made exit 19 northeast corner,

building three ground level.

Copy that.

Maynard.

Exit 19, no sign of Maynard.

He's on his way.

I'll intercept.

Rodger 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, Rodger.

Stay here.

Tariq, something's wrong.

He's not here.

Make contact again, I'm gonna go look for him.

Maynard.

Where are you?

Your contact's at Exit 19.

I was told there was a change of plan.

Are you with Lucas North?

Hold it right there.

Don't think I'd hesitate.

Drop it.

Kick it.

Hands where I can see 'em.

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 outta jail free card.

Sarah!

Tariq, ambulance.

We're on the third floor.

I tried to stop him.

You're okay, Rodger.

You're gonna be fine.

There's an ambulance on the way.

Look at me. Look at me.

Do you recognize the man who did this to you?

His name's Jack Coleville.

He was with MI6.

How'd you know him, Rodger?

Look at me. Stay with me.

I need to know why Coleville targeted you.

Baronova. Mina Baronova.

Who is she? Is she Russian?

Come on, Rodger. Fight it.

Fight it!

Coleville got away.

That's unfortunate, Sarah.

You better rethink your Walker problem.

I'll deal with it.

I think Maynard made it up.

Nothing's coming up on Mina Baronova.

I've tried alternative spellings,

Cyrillic, Arabic, and Hebrew alphabets.

All drawing a blank.

I've got a Mitko Baronov, Serbian militia.

He's at the International Court of Human Rights.

War crimes?

As a witness.

Get a full transcript of his evidence.

Sarah Caulfield checked out Braden's records.

He was in Bosnia in the '90s

when he was with special services.

What are we missing here?

What's the connection?

Okay, we know Coleville and Braden

were in Bosnia in the early '90s.

Winchcombe was an expert in Serbian Croatian dialects,

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

which leaves Maynard, 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 is through Braden.

He's never posted to the Balkans.

Now he only met Braden in Washington.

I've got something on Mitko Baronov.

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 five years ago,

but I can't find any other reference to her.

She has no medical records, tax records,

no bank accounts, passport application, nothing.

It's as if she never existed.

Well, maybe that's exactly how they want it to look.

Shadow Protection Program.

Created by Six during the Balkans crisis to protect sources.

Informants 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 Baronova's case officer.

Now he was running her as an informer.

She must have been compromised.

He arranged a new life for her.

Yeah, until five years ago, she was living in Greece.

A place called Spata.

And 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 killed 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 'til tomorrow.

Approaching now.

Home sweet home.

Check. Flat's clear.

Alpha team standby, vision on Lima One.

Alpha four. Update.

Lima One approaching property now.

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?

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 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.

It's over, Jack!

Contact made.

Stand by, everyone.

Ros.

Put the gun down, Ros.

Hands where I can see them.

I'm too old for this kind of thing.

Why?

No, 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 realize that.

It's not easy.

Ros.

I dunno myself half the time.

It's all such a mess.

Okay, move!

All units, go, go, go!

Lucas, I've lost Ros's comms.

Ros, where are you?

Ros?

Ros's 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.

Just give me the gun, Ros.

Now just keep going.

Don't look back.

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 Baronova?

You signed her death warrant.

I dunno what you're talking about.

Please.

When you wanted to turn Mitko Baronov, 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 Braden wanted some scrap of information

from her shit 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 war on, Jack.

Not where they caught out with Mitko.

It was all over there.

Do you know what he did?

He burned a lorry load of Muslims to death.

They wanted him on trial for war crimes,

and then some smart young officer in London realized

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.

Didn't take them long to find Mina.

Little help from the Belgrade office,

and Mitko was on his way.

Do you wanna see what your signature did, Ros?

He didn't kill 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 authorization?

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.

Could have been me, it could have been anyone.

Even you, and 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 okay 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 is 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.

It's the last place I wanna be.

What's up?

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

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 meters 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 a hang

of the special relationship.

Yeah, I'd tell you were getting that.

I'm sorry I've been so, you know?

Walker's death threw me.

I understand.

Do you?

Can't have been easy for you.

No.

Being close to someone,

finding out they're not who you thought they were

is painful.

I'm just glad you got the guy who killed him.

We didn't.

Coleville didn't kill Walker.

It was my fault then.

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

told me he'd come by the office later,

and I just stayed home all night,

and he must have known we were onto him.

That's why he jumped.

But I should have insisted

I should have gone to see him right then.

I could have stopped him,

and maybe if I had been there, he'd still be alive.

It's okay.

It's over now.

You can't change the past.

You're sure about this?

She lied. Plain and simple.

Sarah killed Walker?

Yeah, yeah, I think she did.

I've run out of other explanations.

Okay, 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.
