Okay.

Go.

ALL: Oh.

WOMAN: Okay, ready?

MAN: She’s not going to get it ( indistinct ) MAN: Come on.

ALL: Oh.

( cheering ) ( indistinct chatter ) Take care.

Right, see you later.

WOMAN: All right sweetheart, see you later.

Bye guys.

I was gonna say, do you want a lift?

Yeah, yeah, that would be lovely.

Yeah.

Yeah, cool.

Okay.

Well, I’m just parked round here.

MAXINE: Okay, cool.

All right.

( engine revving ) So... So... You took your time.

I was just picking my moment.

For three years?

You know, this thing.

Well, me and you.

It’s not just... ( indistinct shouting ) Just get off!

Move it now like--yeah.

Just ignore them, just ignore them.

It’s going to be all right.

( indistinct chatter ) MAXINE: ( screams ) Come on!

Go on get him out!

( indistinct chatter ) CALLUM: Max, run.

Run, Max.

Run!

MAXINE: Help us.

Help us.

Help me.

Get off me.

Help me!

Hey, help me.

Please, please!

Hey boy!

Hey boy, come and get ( indistinct ) Ah, nah, nah, nah, stay here, stay here, stay here.

Hey, pass me this.

How can I help you?

What is it, bruv?

You gonna do me something, yeah?

What are you deaf?

Hey deal with him, man!

Run!

Run!

Stop!

Put your hoods down.

Hoods down!

Go on run, run!

( gunshot ) Oh, Callum.

Oh, please.

Please, just wake up.

Please, Callum.

Oh, please.

Why?

JUSTIN: Well, you never ask me in.

Not ever.

Mmm.

Mary?

Oh, sorry!

This is my mate, Justin.

Hey there.

Hey.

JOHN: Justin, this is Mary.

All right, Mary.

He’s my mate.

And I love him.

Right.

Work!

You gonna be all right?

MARY: Fine.

Yeah?

Fine, yeah.

Make yourself at home.

Will do.

Totally.

JOHN: Well, come on then, Justin.

Nice to meet you, Mary, briefly.

Yeah.

JOHN: All right, boss.

MARTIN: Victims are Steven Meredith and Shaun Butler.

This is Meredith.

Murdered a young solicitor, six years ago.

It’s in the file.

Who’s the other one?

Over here.

Shooter walks up during the affray, puts the sawn-off to Butler’s chest.

JOHN: Doesn’t hesitate?

Apparently not.

It’s not an easy thing that-- to put a sawn-off to someone’s chest and pull the trigger.

So, who’s Caitlin?

Well, we turned up no "Caitlin" in Meredith and Butler’s ambit.

No family, or known associates.

There’s no Caitlin connection to the solicitor.

That rules out a revenge attack.

And this is way too heavy for a gang beef.

So, what’s up with the web site?

It goes live in two hours.

JOHN: Well, can’t we just pull it down?

Or trace it to the source or whatever you do with websites?

MARTIN: Apparently not.

It’s being hosted from Uzbekistan or Kazakhstan.

One of the Stans, anyway.

The upshot is that there’s no way we can pull it down in time.

Apparently there’s hundreds of these leaflets already in the wild.

People have been tweeting the address since about 5:00 A.M.

( music playing ) ( knocks on door ) Hello, Mary.

( music playing ) JOHN: Maxine, I’m DCI John Luther, you alright?

This man, the killer, he spoke to you?

He did, yeah.

What did he say?

He told me not to be afraid.

Do you remember anything about his voice?

Maybe he had an accent?

It was nice.

In what way?

Kind.

He had a very kind voice.

He had a kind voice.

And then?

He sat and he held Callum’s hand until the ambulance arrived.

Can you describe him?

Sorry?

Describe him.

The killer of these men.

( music playing ) Why?

Maxine, they’re dead.

Now, I know he seemed kind.

But that doesn’t give him the right... MAXINE: What?

To give him the right to save Callum’s life?

Stop me from being gang-raped?

The way I see it, two people were going to die last night.

Thanks to this man, and no thanks to the police by the way, it wasn’t me and it wasn’t Callum.

And now you’re asking me to help you send him to prison?

I would rather go to prison myself.

GEORGE: So, how did you and John meet?

I’m sorry, I’m just not very comfortable having this conversation.

How much do you actually know about John Luther?

I’m not actually sure what that means.

Look, why don’t-- why don’t we just give him a ring and... GEORGE: Put it this way, try... if you like.

ERIN: Does he ever talk about her?

Well, he doesn’t not talk about her.

Okay.

I’ve actually got to go.

Sit down.

I’m late for work.

Did John ever mention how she died?

Um, I’m not actually sure that’s any of your business.

She left him.

Shacked up with another man.

And not long after she was killed.

Did he mention that?

MARY: I’m sorry.

I’m not sure what’s supposed to be going on here.

I’m... completely lost.

GEORGE: That’s why we’re here.

To help you understand how lost you really are.

( music playing ) JOHN: You all right?

Yeah.

Cut it down to about 14 possibles.

It’s just weird.

Seeing all these terrible things happening to women with the same name.

Caitlin raped, Caitlin stabbed, Caitlin drowned.

It just seems-- I don’t know.

Justin, I think it’s time you moved on, mate.

I mean, you should be doing my job.

Having little Ripleys of your own.

I’ve been meaning to tell you that for a while.

You need to get to Hamlyn Woods.

All right, Guv.

Do we know who he is?

Yeah, Liam Glass.

Why’s that name sound familiar?

For a few months, he was the tabloid’s favorite bogeyman.

Because?

He lived in the spare room of the flat where Lucinda King died.

Ah, the little girl.

Yeah.

Four years old.

Mr.

Glass was her stepfather’s cousin.

Crack cocaine addict, arsonist, career burglar.

Sat by and took no action while her mother and stepfather starved and beat her to death.

Well our boy’s killing predators, isn’t he?

People the justice system spat out.

He’s on a mission.

We better find him, find him fast.

( music playing ) BENNY: It’s going live now boss.

By now, many of you will be wondering who "Caitlin" is.

She was my wife.

This is Caitlin.

Four years ago, she was raped and murdered by a man called Milan Knizac.

Mr.

Knizac had been classified as "medium risk" by probation staff when he was released from prison less than halfway through a nine-year sentence for robbery with violence.

The criminal justice system was created to protect us from people who would do us harm.

But time and again, it fails in that purpose.

For all the Caitlins, and for all their families, it’s time for that failure to end.

Okay.

I think we got a big problem.

( music playing ) ( cell phone chimes ) TOM: ...for all their families, it’s time for that failure to end.

( knocks on door ) JOHN: Come on.

Tom Marwood.

Architect.

Pretty good one, apparently.

Caitlin dies, he’s depressed.

Spends a bit of time in hospital.

Then, all of a sudden, boom!

He’s energized.

Joins a gun club.

Takes lessons in Krav Maga.

Urban survival courses.

It’s like he’s in training for the zombie apocalypse.

Wow.

So before this all kicked off, who was he talking to?

Who was his confidante?

Alan Ramsey.

Caitlin’s brother.

This one.

Yeah.

JOHN: Ramsey.

All right, find him.

I’ve got to talk to him.

Guv.

Marwood’s been planning this for a long time.

He’s well-prepared, he’s off the grid.

And we’re not going to find him where he’s at.

We’ve got to find him where he’s going to be next.

And how are we going to do that?

Say we find the ten most debased scumbags in London, put a surveillance team on them.

See if we can’t get to Marwood before he gets to them.

Yeah, well, how do we narrow down the possibles?

I mean, depravity is hardly in short supply in this city.

We collate nature of offense against the volume of press coverage.

It can definitely be done, Boss.

All right, let’s do it.

( music playing ) ( mobile phone ringing ) MARY: Hey.

Can we meet?

JOHN: Yeah.

Are you all right?

MARY: Some people came round after you’d gone.

What people?

MARY: A man and a woman.

Police.

I can’t--I can’t talk about this on the phone.

I can’t.

I need to see you.

JOHN: Mary, all right.

Listen, just tell me where you are right now.

At work.

JOHN: At work?

All right.

Good, I’ll just come now.

No!

No, don’t do that.

JOHN: Mary?

Hey.

Shall we get a cup of coffee or something?

Yeah, in a minute.

You all right?

Yeah.

How did your wife die?

Zoe.

It’s a long-- it’s a long story.

She was... taken... by a friend of mine.

Someone I knew.

And if I’d have asked you that question this morning... before that... Glaswegian dick had done his dirty business, would you have given me the same answer?

Of course.

Why?

Because it’s the truth.

Hey, listen, whatever they said, they were lying.

They had a file on you.

What did you do?

Nothing.

I did nothing.

Whatever they told you, they were lying.

I think you should stay away from me.

Mary, come on.

Please.

( music playing ) ( mobile phone ringing ) Justin.

What?

JUSTIN: We’re down to 263 potentials.

JOHN: Well, we better move faster than that then, eh?

JUSTIN: Yeah, we’ll get there.

Where will you be?

Oh, I’ll be checking out the brother-in-law.

Okay.

( mobile phone ringing ) Hello.

JOHN: George.

John Luther!

How the devil are you?

JOHN: I’m fair to middling.

Have you got two minutes for me?

I’ll put the kettle on.

What?

What are you scared of, Erin?

I’m scared of what this is turning into.

( music playing ) ( doorbell buzzing ) So?

So here’s the thing.

You come for me, I’m fine with that.

But you need to keep away from Mary.

She’s off limits.

But what’s the point of knowing your weak spot if I don’t get a chance to... poke it a bit?

See, here’s the thing, John, this isn’t some pre-match symposium.

There are no rules of play.

George, if you sow these seeds... GEORGE: And what?

I reap the whirlwind, is that right?

You know your problem?

You’ve spent your life thinking you’re the whirlwind.

Well, you’re not.

Because I’m the whirlwind, John.

We’ll see.

( music playing ) A big police search is in underway in London trying to find vigilante suspect Tom Marwood after he posted an online video on the internet at 11:00 this morning.

Marwood made a public announcement... COCHRANE: Oh, no, Marwood.

Please.

( mobile phone ringing ) Hello?

JOHN: Alan Ramsey.

ALAN: Speaking.

This is DCI, John Luther.

This’ll be about, Tom, I take it.

JOHN: Yes it is.

Got a coupleof minutes you can spare for me?

Sure.

I’ll see you then.

Alan Ramsey?

Alan?

DCI John Luther.

Don’t move.

All right.

( music playing ) TOM: Stop!

Stop!

Stop!

Stop!

Well, do me a favor, and throw me your phone and wallet, please.

One out of five murders are committed by men on bail.

You know that?

Every copper knows that.

Then why does nobody do anything about it?

Because it’s complicated.

No, it’s not.

No, it’s not.

You got me there.

Listen.

Detective Chief Inspector John Luther.

All I want is what you want, to have these people locked up, so they can’t do any more harm to anyone else.

Now look me in the eye and tell me you disagree with that.

Not with the motive, maybe.

But I seriously dispute the means.

So you’ve never been tempted?

To administer a bit of personal justice?

I don’t have the right to do that.

Nobody does.

Two days.

Give me two days.

That’s all I need.

For what?

To make things better.

You know, I can’t do that, Tom.

TOM: Yes, you can... if you chose to.

Tom.

You know, they’re going to kill you.

This is how all these things end.

I died the day I came home and found my wife’s corpse stuffed into the airing cupboard.

Don’t make me your enemy, John.

We’re on the same side.

I’m sorry you think that.

Tom listen to me.

Tom!

( indistinct chatter ) DCI Luther?

He’s not here, ma’am.

Oh, okay.

Then I wonder if you could spare me a minute, DS Ripley?

Thank you.

JOHN: It’s alright.

He’s long gone.

I didn’t know he’d be here.

I swear to God.

I didn’t call him, or anything... He cloned your SIM.

He’s a clever boy, your brother-in-law.

Beginning to like him.

You alright?

ALAN: Yeah.

Yeah, I think so.

ERIN: Justin, I think, I may have taken a wrong turn... somewhere along the way.

Surely not.

Well, that wasn’t exactly the disarmingly gallant reaction I was hoping for.

In my heart of hearts.

What were you hoping for?

In your heart of hearts.

( mobile phone rings ) DS Ripley.

Boss?

Yeah.

On my way.

Got to go.

And fight the good fight?

JUSTIN: Listen.

We’ll put it right.

But I really do need to go.

Sure.

Do you want to talk about this properly?

That’s why I’m here.

No, I mean, properly, as actual human beings.

A drink or something?

Oh.

Okay.

JUSTIN: Right well, I’ll give you a bell.

Okay.

( music playing ) JOHN: I know, I know you said to leave you alone, don’t talk to you.

And I will, I just-- I just wanted to say one thing, and then I’m gone.

Say it.

I’m really sorry that you saw what you saw.

I can only imagine how it made you feel.

MARY: It made me want to throw up, it was how it made me feel.

It made me want to vomit.

None of what they said was true.

None of it.

So you need to tell me what is.

I don’t know if that’s a good idea.

Right, well how am I supposed to trust you if you don’t trust me?

I need to know, John.

Okay.

All of it?

All of it.

Every last drop.

( mobile phone vibrates ) I’ve got to take this.

I’m sorry, I’ve got-- I’ve got to take it.

Yeah.

Boss?

MARTIN: Good news.

The proactive strategy seems to be working in principle.

In principle?

What?

A sex offender, Terence Cochrane, was abducted from his flat a little more than two hours ago.

He’s on the list.

But we were too late.

Oh, I had him.

I had him!

Right in my hands and I just let him go.

Well, he had a gun to your head.

So I think it’s more a case of him letting you go.

JOHN: Right, I know.

Just have Benny send me the... address.

All right.

I’m having a horrible day.

It’s okay.

But... I’m going to be back late tonight.

A bit later than usual, I mean.

I will be back.

You know where everything is.

Yeah, I think so.

I’ll be there.

All right.

( music playing ) You all right?

Cochrane’s a pedophile.

Did 15 years for false imprisonment and rape.

Bit of a tabloid nightmare.

Went on to self-publish poems and essays about "inter-generational love."

Sees himself as a champion of freedom ungoverned by religion or law.

Yeah, I’ve heard that one before.

Lack of conscience, dressed up as philosophy.

It’s not right, is it?

What’s not?

JOHN: Well, Marwood walks up to Butler and Meredith, bam!

Doesn’t do the same with Cochrane?

Why’s that?

We find any keys?

Not that I’m aware of, no.

Why?

Well, it’s what you do, you know.

You walk in.

Big bag of books in one hand, plop them down.

Put your keys on the table, fish out your wallet and your phone.

Yeah.

Okay.

So who took his keys, and why?

My name is Terence Cochrane.

Boss!

I’m a pedophile.

I spent 15 years in prison for the heinous violation of young children.

I’ve shown no contrition because I don’t believe sex between adults and children to be wrong.

But still, the criminal justice system set me free.

So what should be done with me?

Terence: No.

( knocks on door ) If Tom Marwood gets his wish and people vote to hang the pedophile, and they will, for who would suffer a pedophile to live?

Then there’s no telling where this is going to end.

Riots, copy-cat, murders, lynchings, pogroms, gangs of vigilantes kicking to death, people whose faces don’t fit.

Where is your head at?

Well, we’re not going to find Tom Marwood before midnight.

But if you’re right, if he executes Cochrane, this all gets very ugly, very quickly.

But we know he’s monitoring the media.

And you’re right.

There’s nothing more potent than private pain made public.

Please... JOHN: Excuse me, mate, Kiera Mills?

MAN: Over there.

Kiera?

Kiera Mills?

KIERA: Do you know what that man did to me?

Terence Cochrane.

I say "man".

Do you know what he did?

Yes.

I was a little girl.

I was 11!

And he... JOHN: Kiera, I should explain to you that I have no sympathy for Terence Cochrane.

All right, not one bit.

But I don’t get to choose who should live and who should die.

Even if I hate them myself.

This is the hardest thing I’ve ever had to ask someone to do.

What do you want?

( music playing ) I want you to plead for Terence Cochrane’s life.

Benny Boy?

BENNY: So I’ve been trawling a list of Cochrane’s known associates.

Nothing solid but about a month back, a parole officer got a tip-off that a nonce Gordon Murray was in breach of his parole, associating with known sex-offenders.

Cochrane’s not been named, but him and Murray were known to be BFFs.

Right.

Where do we find Murray?

All right, Gordon.

We’re the filth.

Which is funny, really.

Considering who we’re talking to.

Shall we try that again?

I’ll have a lemonade, please.

( music playing ) TERENCE: Help.

What do you want?

WOMAN:...to remain calm and not to respond to the suspected vigilante’s appeal.

They say Marwood could be unpredictable and dangerous.

Everyone wants him dead, your mate Terence Cochrane.

King Nonce.

He’s got less than an hour.

I think you know where he is.

How could I?

JOHN: I think Tom Marwood’s been following you.

I think he’s taken Terence back to your club-house where you and your dirty little mates have your social gatherings.

So where is it?

Back of someone’s pub?

Dirty little shop somewhere?

Come on?

No, you’ve got it wrong, mate.

I’m not your mate.

I’m far from your mate.

The sight of you makes me want to wash my skin with Domestos.

The terms of my parole forbid me from using the internet or mixing with other sex offenders.

JOHN: Is that right?

Boss.

Can you turn that up please, love?

MARTIN: Thank you very much, ladies and gentleman.

I know you are all aware of how urgent this situation is.

So Kiera, will now make a short statement.

My name is Kiera Mills.

You don’t know me, because I was never named in the press.

But 18 years ago, when I was a little girl, Terence Cochrane stole me from the back of my mum’s car.

She’d just popped to the shops to get some milk.

Terence Cochrane kidnapped me and raped me.

He ruined my life.

This morning, a man kidnapped Terence Cochrane and threatened to kill him for all the terrible things he has done, not just to me, but to other little boys and girls.

Help!

So I have come here today to send a message to the man who has Terence Cochrane in his keeping.

And that message-- that message is kill him.

( indistinct chatter ) TERENCE: ( grunting ) Help!

JOHN: Right.

You tell me where he is or when they come for you, I’ll let you just hang.

Don’t look at me, mate.

JOHN: Come on!

All right!

There’s a lock up.

A lock up?

Where is it?

We use it for meetings.

Socializing.

You disgust me!

Come on.

GORDON: If I tell you, you might find some materials... Shut up, shut up, shut up!

Where is it?

GORDON: None of it’s mine!

I want that in writing.

Where is it?

GORDON: None of it’s mine!

Tell me now.

Horsemonger Lane.

The railway arches.

You just-- all you do is cross the estate.

JOHN: Benny!

Cochrane’s got a lock-up, railway arches, Horsemonger Lane.

Scramble ARV now!

( music playing ) No.

No.

No.

Please.

Oh, God, oh, oh!

No.

Please just... Please.

No.

No.

Oh, God.

Oh, God.

BENNY: CO19 are en route.

ETA 13 minutes.

Local units should be there in nine.

Wait boss, he’s tweeting the address!

We’re on our way.

We’ll be there in two, three minutes.

( music playing ) Watch out!

( indistinct chatter ) JOHN: Move!

Move!

Move!

( indistinct chatter ) Quiet now!

( cheering ) ( indistinct chatter ) Stop right now!

Thomas Marwood!

Enough!

( cheering ) Move!

Ah, come on!

Oh!

( indistinct chatter ) Get back!

Get back!

Go!

Get Marwood!

Get him off!

( music playing ) ( indistinct shouting ) ( sirens wailing ) ( indistinct chatter ) He’s still alive, not dead!

( music playing ) JUSTIN: Tom Marwood!

Stop!

Okay.

Enough.

We’re done, Tom, all right?

What’s your name?

DS Ripley.

Justin.

What I need you to do, Justin, I need you to back away.

I can’t do it.

Of course you can.

No, I can’t.

Sorry.

You’ve already done enough tonight.

I saw how you waded into that mob.

That was brave.

Nobody could ask any more of you.

So just... back off.

Let me go.

Say I did that, yeah, and all this carries on.

Someone innocent gets hurt.

How am I supposed to live with that?

It won’t happen.

It’ll happen.

You’ve made your point, Tom.

People are talking.

You’re all over the internet.

All over TV.

You’ve done what you needed to do.

I don’t want to do this.

( music playing ) I’m a copper.

We’re on the same side.

I don’t think you’re gonna shoot me.

Now please.

Just back off.

I’d love to.

Please!

No.

( music playing ) ( music playing ) JOHN: Justin!

Justin!

Ripley!

Hey.

Hey!

Hey!

No.

Don’t you-- don’t you--hey.

Get up!

Justin!

No!

Get up.

No.

No, mate.

Get up.

Get up!

WOMAN:...several people including some police officers have been hurt after a crowd in east London turned violent.

The police had intervened in what vigilante, Tom Marwood... JOHN: It’s John.

Leave a message.

TOM: I asked you nicely.

Now look-- now look what happens!

This is your fault.

This is on your head.

I warned you not to make me your enemy!

I warned you!

( music playing ) The public execution of sex offender Dennis Cochrane.

Marwood’s whereabouts are currently unknown.

Police say the suspect he is armed, and extremely dangerous.

They say anyone who believes they’ve seen Marwood should...
