[action music playing] I'm going to send you to a series of checkpoints.

You won't know the final destination until you arrive.

Mark isn’t a part of this.

I need to know that he's walking away.

Do as I say, he gets to go home and watch The One Show.

[Luther] And Alice?

Sorry.

You know how it is.

I still need to know he’s all right.

I need proof.

You have my word.

I said I need proof!

Stay by your phone.

[action music continues] [music intensifies] [phone ringing] Hiya.

Yes, yes I did.

-Organic, yes-- -Excuse me.

And the kitchen roll.

No, no.

I got Braeburns instead.

-Sorry, excuse me!

-In about ten minutes.

Yep, love you.

Yes.

Yeah.

Love you-- -Sorry, excuse me.

-Bye.

I’m so sorry!

I'm afraid you dropped this.

[eerie music playing] [camera shutter clicks] [theme song playing] [Mark] "Stay away from the door," he said.

[Alice] He's not here, is he!

He's out there.

Preparing to kill John, and then you, and then me.

If that's what he wants, why hasn't he done it already?

[Alice] John wouldn't come here without proof of life.

Well, your life anyway.

Mine, not so much.

[groans] You'd make a good bag lady.

Thank you.

Listen, we need any scrap of insulation we can find, or we’ll have frozen to death by the time he gets here.

[dramatic music playing] [grunts] Don’t you give me the runaround.

Don’t you give me the runaround.

[phone ringing] Guv, where are you?

So, it turns out-- Look, Catherine, I need some help.

What sort of help?

I just need you to find someone for me.

His name is Ronald Massey.

He works for a man I need to find.

I mean... Guv, I can't just... I mean who is he?

Look, Catherine, I'll be there as soon as I can.

I'll bring in Jeremy Lake.

But I need you to do this first.

Can you just do it?

-Boss-- - Catherine!

Do it!

[horn honking] [Catherine] Massey.

Ronald Massey.

[labored breathing] [Catherine] The mask’s of Lake's own face, which is new behavior, as far as we know.

But it is consistent with some of the images in the diary.

[Schenk] His condition disinhibiting him?

Yeah, or maybe, he knows we're breathing down his neck and he’s decided to go all Carpe Diem on us.

Do we have the faintest notion where DCI Luther is!?

Sorry, boss.

Vivien Lake knows her husband's mind.

She's the only one who can help us get ahead in this.

Well, she's being treated at the hospital.

Wheel her in on a gurney if needs be!

Hey, guv.

I don't know what your other thing is, but the Big Boss, he’s on his last nerve.

And I don’t feel comfortable lying for you.

Things are really kicking off here.

We need you.

Hello, I'm enquiring about the availability of Illeana this evening.

Overnight for preference.

Good.

Thank you.

[eerie music playing] Yes, hello, King of Plumbers, I have a dreadful smell coming from my drains.

[Schenk] Dr.

Lake.

If you follow me please?

[alarm ringing] [Masey] Boss, we should probably go.

Nah, sod it.

It's just a drill.

[Massey] They usually say when it's a drill.

I will go when the hair on your bollocks starts to sizzle!

-Just let me go and check.

-OK.

-[music intensifies] -[fire alarm blaring] [action music playing] [grunting] Call him off.

[phone ringing] We're on schedule.

Luther should be here soon.

Yeah.

I actually need you to hold off on that for a bit.

Why?

Because that's what I want!

We entered into a contract.

You'll get your money.

Just tell me where they are and take the rest of the day off.

Go to the pictures or something.

It's not that easy.

A police officer is dead.

I can't have that coming back on me.

It won't come back on you.

Just text me the address, pack your sandwiches and go home.

I'll make sure everything is tied off.

He says a copper's dead.

Yeah.

-That’ll be your mate-- -Yes.

For what it's worth, I didn't ask for that.

[gun cocking] I came to off you for Benny.

I'm going to end this.

[tense music playing] All this "eye for an eye."

It's all just a game, isn’t it, George?

You don't want this!

You don't want any of it.

Do ya?

You lost your discipline, George!

You robbed Alice.

She robbed you back.

Now Alistair's dead.

That's not her fault, that’s your fault!

Benny’s dead!

That's not your fault, that’s my fault.

I couldn't shoot you 'cause I made a mistake.

But if you can shoot me, go and do it.

Doesn’t change anything, does it, George?

What I lost was my son!

[sighs] Take it.

Eye for an eye.

You think I won’t do this and piss on your body after?

Go on, George.

Just do it!

That's it.

Go on!

[Palmer] Stop there.

Do you have a gun?

Oh.

So where's Luther?

He’s in the boot.

Dead?

As a dodo's granddad.

How did you find him?

He came to me, as it happens.

And how did he find you?

I'm not entirely sure, to be frank.

But there you are.

He was a clever old sausage.

But not bullet-proof, as it turns out.

-Open the boot.

-[George] Oh, come on!

Now if you will.

Open the boot.

All right.

All right.

As you speak, so shall it be.

Oi!

I don't get it.

Peace in our time.

I'm Adolf.

He’s Neville.

You're the Sudetenland.

You’ll go down, go to prison for killing my friend.

Do you understand that?

And if I don't agree?

I shoot you dead right now and tell a story to my boss.

[tense music playing] No!

What did I tell ya?

You're going to jail.

And you're gonna hate it-- [Cornelius] Sorry, old bean.

Couldn't take the risk.

-[camera shutter clicks] -There we are.

You, smoking gun, damning evidence and what not.

All in the cloud.

Whatever that actually is.

I’ll have the gun.

I think it's one of mine anyway.

You're a clever one, ain’t you, George?

You would have been a good copper.

No.

I'm too honest to have been a copper.

Schenk came to me, John.

He knows something's not right between me and you.

I’ll sell this to Schenk.

He trusts me.

And so do I, but only 'cause I’ve got this.

[object clattering] [Luther] Alice?

[eerie music playing] [Mark] Is your friend in there?

Yeah.

[Mark] Aren't you going to call someone?

They'll find him.

We can't just leave him here.

[Luther] We have to.

[Mark] For God's sake!

He's your friend.

Do you think I want to be doing this?

Mark, do you think I wanna be doing this?

Benny's dead.

The man who killed him is dead.

All I'm trying to do is handle it so that your name is clear!

What time does your wife get back?

I don't know.

Half-seven.

Quarter past?

I think we need to get back and clean the scene.

What’s happened to you, John?

[car door closes] [Alice] What about the George Cornelius problem?

Have you dealt with it?

Yeah.

Let's not be coy.

Is he dead, John?

Yeah.

Because it's the only way.

He'll kill us both.

You do know that.

Alice, it's done.

You wouldn't lie to me, would you, John?

Not about something this important.

[dramatic music playing] No.

Because you're the only person I ever knew who always told me the truth.

Come what may, you never lied to me.

It's done.

[phone beeps] That'll be your fancy lady calling you in for tea.

[Luther] Oh, why don't you just give it a rest.

I've got to deal with this thing.

Deal with it then!

Just go home.

And we’ll talk later?

[Alice] Good luck with your whatnot.

[engine starting] [phone ringing] [George] Hello?

Hello?

Who's this?

Hello?

[Luther grunts] [Schenk] We know your husband is gravely ill, Vivien.

Jeremy doesn't have long.

One more Christmas, perhaps.

But he'll never see another summer.

Now, if we can find and detain him, his case will never get to court.

He'll never go to prison.

The worst he can expect is a few months in a secure hospital.

But he will stop.

This will stop.

This... will stop.

[eerie music playing] It will stop!

[sighs] I have no idea about Jeremy's activities.

I'm as horrified as you are.

Oh, I doubt if you have the capacity.

And to be fair, we did catch you in a plastic-lined room, getting ready to disarticulate Penny Leyton with surgical tools.

I'm afraid you misinterpreted that situation.

Actually, I was there to rescue her.

Get her out of there.

Poor thing.

But you were wearing the surgical scrubs and were attacking her with a hammer.

I was defending myself from a very confused and frightened young woman, who understandably, given her state of delirium, misread the situation and believed, incorrectly, that I was there to do her ill.

[Schenk] I have to make a call.

We’ve had some urgent news.

Let's hope it's the news we all want, eh?

DS Halliday, if you would hold the fort, please.

Where have you been?

I got called away to something that didn’t pan out, boss.

Any news from Benny?

No.

No, he called in sick.

I've been called away.

I want you in there with Vivien Lake.

On my way.

[Schenk] What do I need to know?

Sir.

We were investigating reported gunshots.

You might want to get somewhere private.

[Schenk] I am somewhere private.

Go ahead.

[peaceful music playing] We found a disposable phone in the glove box.

Most likely any calls were made to another burner.

[Schenk] Fine.

So I will need you to determine where that phone was last used.

See if you can find any CCTV footage corresponding with the time and place of that usage.

Absolutely.

I want this now.

And this stays schtum.

Are we clear?

Nobody says a word.

Sorry I'm late.

I’ve had a very busy day.

So, where did you meet, you and Jeremy?

Is that relevant?

I dunno.

We struck up a conversation at a dinner party talking about Tony Blair, over baked brie and raspberry jam.

That's not true.

You met at a "Play Party."

Basically, a fetish club.

You really are bourgeois little prudes, aren't you?

Thought police.

Sex police.

Erecting an edifice of speculation on a foundation of puritanical distaste.

No.

That's not what I'm doing.

I’m basically trying to establish whether you would lie to protect your privacy.

And the answer turns out to be yes, which I find very interesting.

Did you know that Jeremy kept a diary?

Bit of a leap to conclude that's a "diary."

It looks more like a sketchbook to me.

Okay.

What about these?

These are actual drawings of murder scenes, which makes me think about these other sketches too, which were, well, I don’t know.

Are these real too?

Clearly not!

It’s an explication of Jeremy's fantasy life, an outlet.

A masturbatory aid, nothing more.

Yeah, possibly, could be, but it's not just the drawings, is it?

I mean, it’s the text.

[Vivien] That'll be a cipher-text of Jeremy's own construction.

Well, God knows what it says.

Do you think you could decipher it for us?

I'd love to.

But very much doubt I'd be able.

You have to get rid of this stuff properly.

No throwing it away in your own bin.

Thank heavens I'm here with a criminal mastermind.

Otherwise, whatever would I have done?

I have to go, Mark.

I promise you won’t see me again.

That would be a shame.

Some valedictory advice.

Don't let John Luther back through your door.

He’s not what you think he is.

You have to stop.

God knows you are what you are.

But you're not a psychopath.

You're not... I know.

Do you need help?

Is there something I-- Hello!

[Luther] I had a boss, once.

Her name was Rose Teller, really good cop.

She used to say, "An assumption is something you don't know you're making."

Do you know the assumption you're making, Vivien?

I might be able help to answer that?

You're assuming that Jeremy doesn't want people to read what he's written.

Then why employ a cipher-text in the first place?

Because he doesn't want you to know what he's written.

He doesn't want you to know that he's written it all down.

Everything that you've done.

Together.

Dates.

Times.

Places.

'Cause that's the difference between you and him.

You are very private, don't want anyone to know the truth about you.

Not ever.

And he is very proud of what he's done.

He's done with being anonymous.

He's done with someone else taking the credit.

And where does that leave you?

-I don't know what you-- -Yes, you do!

You do Vivien, don’t ya!

You know exactly where that leaves you, if Jeremy has implicated you as an accessory to murder.

You know exactly what that means.

Obviously, he wouldn't do that.

Are you willing to bet the rest of your life on that?

[Luther] No.

Course you’re not.

Because he has been letting you down recently, hasn't he?

Come on, Vivien.

Help us and we can help you.

You are going to prison, Vivien.

But for how long is really up to you.

May I have a glass of water, please?

No, you may not!

[tense music playing] Jeremy's most outré fantasy, and I have to stress to the best of my knowledge, it was just a fantasy, was to play a game of what he called Happy Families.

To sit in a house and summon people to him.

Have them turn up at the door.

Lambs to the slaughter.

[doorbell rings] [DCI Woodgate] Sir.

The phone was used here.

He arrives alone.

George Cornelius.

All right, George.

You wanted it old school.

[doorbell rings] [Jeremy] Thanks for coming so quickly!

Yeah, no worries.

So what're we looking at?

Through there.

[Halliday] So, Jeremy Lake's gone to ground.

He's holed up somewhere getting people to come to him.

How are we supposed to find him?

There are like 60,000 streets in London.

And previous murders, they don't tell us anything.

There's no pattern.

They're random.

They’re not disorganized, are they?

[eerie music playing] I mean, everything he’s doing, he's doing to tell himself how clever he is, and, oh, the audacity of that... I mean... He can take out whoever he wants, whenever he wants.

He can have the police run around in circles.

He can make the police blame the wrong man.

And then he’s come to an end.

Which means he's gone somewhere, significant with meaning.

-To who?

-To us.

To him.

And if you were him, where's the most audacious place you could go?

[sighs] If I were him, I would go home.

[Luther] No, too big a police presence.

Where's the next best equivalent?

Well, if I couldn't go to where the police are, -I'd go to where they just left.

-Left.

Right, yes.

Ballarat Street, the school teacher!

Should we tell someone?

No.

Not until we've checked it out.

-Are you sure?

-[Luther] I am sure, come on.

[suspenseful music playing] [music continues to play] [doorbell rings] [Jeremy] Illeana?

Wow!

You look lovely!

Please.

["I'll be seeing you" playing] [action music playing] [shouting indistinctly] Move to the counter!

Do not move!

[George] I think it’s time maybe we discuss getting me some legal protection.

I can't put it together, George.

I've tried.

But I can't work out what happened.

I need a show of goodwill, an upfront payment, right now.

[tense music building] [George] Now I told you Martin, your lad’s a wrong un.

[phone ringing] -Hey, boss.

-[Schenk] DS Halliday.

Are you with DCI Luther?

Yeah, I am.

Now, I need you to listen to me very carefully.

Without alerting DCI Luther to this order, I need you to bring him back to the station as soon as possible.

Okay, yeah.

If you alert him to this, there is every chance that he will run.

Do you understand me?

[Halliday] Yeah.

Got it.

[Schenk] Good.

Now get him back to the station.

Tell him I have some interesting news that I want to give him, face to face.

Schenk has asked you to bring me back in, hasn’t he?

Oh, yeah.

Yeah.

He said he’s got some news?

Something to tell you?

Fair do’s.

[calm music playing] I'm not going anywhere until this is dealt with.

You think he's in there?

-I know he is.

-How?

Plumber's van.

Pest control.

Food delivery.

All people that will come to you.

We can get back-up in nine, ten minutes?

We’ve got no evidence.

If we call it in, we'll have to go through due process.

Get a warrant.

It'll go on and on.

And what does that mean for anyone alive in there now?

If you found out tomorrow, that if we went in there today, you could've saved someone’s life, would you be okay with that?

Boss.

That's not fair.

Right.

Do what you have to do.

[cellphone vibrating] [thuds] [tense music playing] [music continues to play] [doorbell ringing] [man] Pizza delivery.

-[doorbell ringing] -[knocking on door] [Luther] Catherine.

Get rid of him.

But what about you?

[man] Pizza.

[doorbell ringing] [knocks on door] [tense music playing] Catherine!

Catherine!

[grunting] [Halliday] Stop, boss.

-[Luther grunts] -Boss.

[laughing] What did you think?

Did you like it?

[grunting] [handcuffs snapping] You okay?

Yeah, yeah.

You should know.

Schenk's on his way.

[Luther] You called it in, didn’t ya?

-You know they're coming for me?

-Yeah.

What did you do?

Nothing I can't fix.

I just need time.

Are you asking me to let you go?

Catherine, I have to go, okay?

It's a mess.

But it's not what it looks like.

I promise you that.

Can I stop you from leaving?

No.

Then I won't try.

John.

Did you use me as bait in there?

Send me downstairs to lure him out?

No.

I think you did.

I think you dragged me here and threw me in front of him so that you could be the man to stop him.

That is not what happened.

[gunshot] [suspenseful music playing] So what did happen?

Why are you making such a fuss?

I mean, this is what happens, isn't it?

To those of us who are no longer useful.

Who's next?

Could it be me, I wonder?

No.

I won’t let that happen, John.

I can’t allow it.

She did nothing to you, Alice!

Neither my parents, really, or Henry Madsen, or Ian Reed.

You never seemed to mind really though, did you?

What are you going to do this time, DCI Luther?

Arrest me?

Well, yes, you should.

But you won’t, will you?

You'll let me go.

Because think of the tales I could tell.

But how are you going to cover this up, I wonder?

What lies can you tell?

Quick, John!

Think of a lie!

Come on!

Think of a lie!

Put it down.

Make me!

Liar.

Liar!

Liar!

Next one's in your mouth.

Put it down, Alice.

In a minute, liar.

In a minute.

-[groans] -Oh?

Oops!

[police siren wailing] [dramatic music building] [tires screeches] [panting] [tense music playing] [gunshot] How many more bullets, Alice?

[Alice] Come and see, John.

Honestly, I'm embarrassed.

I can't believe it took me so long to see that Zoe was right about you.

You don't care about anyone, John.

Not unless they can feed your compulsions.

Friends.

Enemies.

It’s all the same to you.

It doesn't matter.

Even Zoe, you loved her so much more when she was dead-- You need to stop!

It gave you an excuse to behave exactly how you wanted.

[Luther] You need help!

It's just words, isn’t it, Alice?

It’s just words, trying to justify what you really came here to do.

And what's that please, do tell me?

Free yourself.

From this.

From me and you.

You’re never gonna get what you want, Alice, never.

I ain't coming back.

Because what I want doesn't exist.

[Luther] No.

So how many more bullets, Alice?

Yeah, I’ve got enough.

Enough!

[Luther] How many more!

[both groan] [suspenseful music playing] [breathes heavily] [panting] [laughs] What now, John?

Alice Morgan, I'm arresting you for the murder of... For the murder of Sergeant Catherine Halliday.

[continues laughing] Of course you are.

You have the right to remain-- [groans] [Alice] The thing is, John, you don't understand love.

You know, you can mimic it, you can recognize it in others.

But you can never understand it.

Is this it?

Is this it, love?

Yes.

Guess what?

I lied too.

There's one bullet left.

I just needed us to be really close.

[dramatic music playing] Good night, John.

[grunts] [Luther] Alice.

You need to help me.

No!

Alice.

[groans] [grunts] [officers] Armed police!

Stay where you are!

Armed police!

Show me your hands, or I will shoot!

Not like that.
