( indistinct shouting ) RICHARD: Somebody stop him!

( indistinct chatter ) RICHARD: Somebody stop that man!

JOHN: I’ve got to go to work.

No.

JOHN: Yes, I have to, because if I don’t show up, they’re going to wonder why.

We can’t afford that.

The police... are not our biggest worry right now, Toby’s grandmother is.

We have to move his car.

Hey.

Hey.

I know what you’re going through.

I don’t think you do.

Only two things matter right now.

Number one, is this was self-defense, and two, I’ll never let anyone hurt you, ever.

Now, Toby’s car is still downstairs.

I don’t think I can do that.

Jenny, listen to me, when we’re scared, we don’t think straight.

Are you scared?

Yeah.

But if we act like scared people, we’re gonna get caught, and we don’t want that, do we?

No.

JOHN: So I’m gonna need you to help me carve some time to think this thing through.

Yeah?

What about him?

Right.

Listen to me, Jenny.

While I’m gone, you’ve got to clean this place.

Use the stuff in this bucket, okay?

Get rid of the bucket.

And I’ll be back as soon as I can, okay?

( door opens and closes ) ERIN: I know what I saw.

JUSTIN: I’m not saying you don’t.

ERIN: So what was Luther doing?

I don’t know.

ERIN: But you asked him.

I did, yeah.

And what did he say?

"Not to worry, just a misunderstanding."

which what you rolled over and let him tickle your tummy.

It wasn’t like that.

Then what was it like?

You’ve got to help me, Justin.

I’m twisting in the wind here.

I don’t know what to do.

I don’t know which way to turn.

I’m asking for your help, and you’re giving me nothing.

JOHN: How bad?

Three dead, four injured.

Stab wounds and chemical burns.

This is the last known victim, Richard Gardiner.

Younger brother.

Brother’s fiancee among the injured.

Killer?

No sign.

SOCO found this, a few 100 yards down that way.

JUSTIN: The killer dropped his wallet in the chase.

No ID, just cash and a keycard.

JOHN: Do we know to what hotel?

RIPLEY: No.

There’s a lot of myths about those.

I mean, all they contain is a check-in and check-out date.

There’s no way to identify the hotel it came from.

ERIN: So what do you think is going on?

Do you think we’ve got a copycat?

No.

I think we’ve got two killers in competition.

If we could find out the rules to the competition, then we can stop them.

Find out what door that opens.

Sir, show me the other site please.

ERIN: There’s an advert on there.

Got anything I can clean that up with?

I’ll see if Benny can do something with it.

MARTIN: Brothers?

No.

More than that.

They’re twins, twins with a shared psychosis.

Turning one will not be easy.

It might not even be possible without a map into their heads.

We don’t even know what their names are.

I think you’re right.

About what?

It’s a scoring system.

You score a certain amount of points for who you kill, and then you get bonuses for where you kill them and how you kill them.

So it’s a, sort of, a tally of experience points.

Experience points?

JUSTIN: Yeah, a way to measure your progress through a game.

So, these men are killing with hammers, knives, and acid because they have yet to score enough points to graduate to better weapons?

JUSTIN: Ah, that’s definitely a possibility, yeah.

MARTIN: And when this man has bludgeoned and stabbed enough people to death, then he qualifies to kill even more people, with, what, guns?

Bombs?

We’ll catch him before he gets to that point.

MARTIN: Ideas as to how?

JUSTIN: Well, we’ve got this.

We think it’s an encrypted password.

To what?

Well, if we can decode it, we can tell you.

So, what do you need?

BENNY: Well, it’s a non-repeating, randomized sequence.

Like a book code?

BENNY: Exactly, like an old book code.

To break the code we need... RIPLEY: We need to know the book that he’s used to make the encryption.

But not just the right title, we need the exact edition.

So, it’s the password is the way into this.

What you got?

ERIN: Uh, the adverts for the Frangipani Restaurant.

I’m checking with the owners to see if they can remember which hotel advertised them on the keycard.

Well find it, call me and I’ll meet you there.

Will do.

I won’t be long.

Uh, Mr.

Kasemsarn?

This is DS Gray from the Serious and Serial Crimes Unit.

I’m inquiring about an advert you put out on a hotel keycard.

JOHN: You know what you’re doing, where you’re going?

JENNY: I think so.

But, what if I get stopped?

I mean, does this look like it’s my car?

Don’t get stopped.

All right?

Buy some SIM cards.

Don’t use one SIM card more than once.

And if you do get stopped, don’t say a word, not even your name.

Tell the duty solicitor to call me and I’ll come get you.

Okey-dokey.

Oi, don’t get stopped.

All right, go on then.

Easy on the accelerator.

( gears grind ) All right, go on.

Put your seatbelt on.

( engine revving ) You’re not very good, are you Frank?

No, but apparently, it’s what you do when you get to my age.

So what happened to your pet polecat?

How do you mean?

Where’s Toby?

He didn’t show?

What can I say, the kid’s an embarrassment.

JOHN: Well, do me a favor Frank, you tell him I need more time, more consultation, and way better manners.

JUSTIN: Right.

Good news is we found this laptop.

Oh, yeah.

So what’s the bad news?

We need to find a particular book to break the password, yeah?

Yeah.

Yeah, well, wait till you see this.

It’ll take weeks.

Yeah, but it’s not right though, is it?

Not right, how?

Well, I mean, in order for a book code to work, you need the exact edition, right?

That way, if you lose your book... You get another copy of the exact same edition.

JOHN: Right, but all this, this lot here this is all second-hand, junk shop copies in it?

I mean, how you gonna get an exact copy of that?

Hey or that.

No.

I need to see another room.

Gideon’s Bible.

There’s one of these in every hotel room in the country.

The key to breaking that code is in this book.

Get that and the laptop back to Benny.

Are you--you know, are things all right?

You solve your problem?

I’m on top of it.

I’ll meet you back in the shop.

BABA: Toby’s missing.

What do you mean, he’s missing?

Nobody’s seen him since yesterday.

Well that’s not missing.

That’s late.

Not for Toby.

Well, he’s had an argument with Frank.

So he’s probably embarrassed, had a drink and decided to screw himself into a coma.

What kind of argument with Frank?

You can’t blame Frank.

I mean, he was doing a decent job.

And Toby, Toby is out of control.

Best I can do is keep my ear to the ground and if I hear anything, I’ll let you know.

Yeah, you do that.

JOHN: All right.

( phone ringing ) John?

Uh, listen, I need you to get out of the flat now.

But I haven’t finished.

Finish and get out.

JENNY: Do they know?

Well, they know something’s not right.

What if they find him?

JOHN: They won’t find him.

But what if they do?

Listen, I need you to get out of the flat, keep your head down for a while, okay?

JOHN: Sorry, Toby.

FRANK: What you... Frank, what are you doing here?

Waiting for you.

What are you doing here?

What’s in the boot, John?

It’s none of your business what’s in my boot.

Open it.

So what are you saying?

I open the boot or you shoot me?

FRANK: Don’t make me answer that.

Frank, do you really want to do this?

All right, all right.

You win.

FRANK: Step back.

What’s in that bag?

It’s me work gear!

All right, me stab and me body armor.

Unzip the bag... JOHN: Come on, Frank!

Just do it!

What a performance.

You happy now, Frank?

Hey, listen.

I’m going to go now and before you embarrass yourself with another senior moment, why don’t you do yourself a favor.

Find your boy, slap him, take him back to his nan.

And while you’re at it, you give him a slap from me.

I’m about done with all this.

[...]!

( John sighs ) JENNY: How did I do?

Did I do okay?

You did great.

You did great.

Well done.

All right?

Well, this isn’t over, not yet.

I need you to find a place to hide.

Do you think you can do that?

I think I might want my mum.

Jenny, I don’t think you should go back there, but if it makes you feel better.

You’re so nice.

Why aren’t you married?

You should be, though.

You should be married.

All happy and everything.

No one will have me.

Go on.

Let’s go.

( car door closes ) ( no audio ) When did it happen?

JUSTIN: Six minutes.

Uniform got there two minutes ago.

And the killer?

ERIN: He ran onto Lyntall Street, but he could be north, south, anywhere really.

All right, so how we doing on the rest of it?

Warm off the press.

All right, cool.

Excellent.

Let’s get that other stuff and get in here.

JUSTIN: Okay.

JOHN: Your password is pretty secure.

Cracked it!

Liverpool Street, this happened.

See what he’s done to compensate for a low-scoring weapon.

He’s used a high-scoring strategy.

JOHN: Hmm, then this.

People carrier, broad daylight.

Males, right?

That’s good, isn’t it, males?

Um, loads of witnesses.

JUSTIN: Again, another high-scoring tactic.

His name’s Nicholas.

You’re name’s Robert.

The Japanese have got a great word for it, "Hikikomori."

It means people that withdraw from the world.

That’s what you and your brother have been doing, right?

Now look at you.

Banged up in here, game over, While Nick... Nicholas.

Nicholas... is out there, making up for all the times he was the quiet one.

What are you asking me?

JOHN: I’m saying that the way Nicholas is racking up a great score, you won’t be winning for much longer, will you?

ROBERT: So?

So, why don’t you help me catch him, before he beats you.

I’ll play you for it.

I can’t do that.

Then it isn’t going to happen.

What are the rules of the game?

It’s a Dilemma Throw.

That makes it a straight 50-50.

Meaning, I roll one to ten, I help you catch my brother.

I roll eleven to twenty, you’re on your own.

JOHN: Go on then.

ROBERT: If you do catch him... JOHN: Yeah?

...tell him I love him.

Sorry.

Don’t be.

This is your home.

You’re welcome here anytime.

Do you want to tell me what’s wrong?

Are you on drugs?

Is it drugs again?

Did he hurt you?

Did that man hurt you?

No.

Then what is it, love?

I really want to tell you, but I can’t.

CAROLINE: Why not?

I just can’t.

So, if Nicholas Millberry believed that his brother had escaped... JOHN: Yeah, this is how he would communicate via the blog.

Run it past me.

Exactly how do they communicate?

Robert and Nicholas set up an everyday blog, okay?

By design, the most boring blog in the world, all but guaranteed to attract no traffic, but if it does attract a passerby... Well, they password protected it.

MARTIN: But you cracked it?

Benny cracked it.

By breaking the book code?

Yeah.

Yeah.

Once you’re in, the blog just consists of boring posts.

And so what, these posts are coded?

Well no, they speak via the comments.

Nicholas have an RSS feed on his phone.

So, as soon as a new comment is posted, he’ll receive an alert.

JOHN: Which means we can control and trace the communications.

Have you got any better ideas?

( voices downstairs ) JENNY: Who’s that?

Oh, God, sorry.

Did I wake you?

No.

So, who was it?

Esther.

Who?

Esther.

Used to live down the road from us on Cavalry Close.

The ginge?

No.

Esther.

The one with all the boobs?

That’s her.

I was supposed to go over and see her but I cancelled for my girl.

Thanks, mum.

John, I think my mom may have done something stupid.

Um, give me two minutes and I’ll call you back as soon as I leave this building.

CAROLINE: Touch a hair on her head and I’ll rip your balls out.

Don’t worry.

You’re doing the right thing.

Now, where is she?

Jen?

Jen?

Genevieve?

Can you come out a minute, please?

Jen?

Where is she?

I don’t know.

I don’t know.

FRANK: What is going on here?

If there is some, kind of, set-up going on here, you are going to be the first to suffer.

Let me tell you now.

Get her for me!

You get her for me!

Where is she?

I don’t know ... Call her!

Call her!

I’ve been trying, I don’t know... Give her a call again!

He’s in there, do I do it now?

JOHN: Yes, do it now, call the police.

Don’t worry about your mom.

JENNY: Promise?

You want to help your mom, you need to keep it together and do as we agreed.

And don’t go back in there, because Frank might not hurt your mom, but he will hurt you, all right?

Okay.

I’ve got to go.

Keep it together.

Do it.

You all right?

Yeah.

It has to come from an anonymous police source.

Police, please.

I’ve just seen a car pull up to this house.

It’s a silver-- how do you say it, Hyundai?

Hyundai, yeah, um... Well, this bloke got out and he was holding this gun or something.

No, yeah, it was definitely a gun.

But, well there’s this other thing, I know this might sound a bit mental... Shut up!

All right, listen, call your daughter, tell her to be back here in 10 minutes or I am going to go to work on you.

You got that?

( phone ringing ) ( siren wailing ) Who called the police?

Is there another way out?

Yeah, up... MAN: Guv, got a body!

John, you clever bastard.

( indistinct chatter ) JOHN: Are we prepped?

Yeah.

Okay.

So I’ve prepared some entries, based on some of Robert’s previous postings.

JOHN: Okay.

What does that say?

Um, "Hello" basically.

Hello?

Nothing wrong with saying "Hello."

Were you never young?

LINDA: DS Gray?

If you wouldn’t mind?

ERIN: Yes, ma’am.

LINDA: DS Gray, you apprised me that DCI Luther used the fire alarm the other day, as a pretext to gain access to Detective Superintendent Schenk’s personal computer.

Yes, ma’am, I did.

LINDA: I had I.T.

run a report on Schenk’s computer.

It shows no activity during the fire alarm.

What angle are you trying to work, Erin?

Is there a plan?

And I hope you’ve got a plan.

This isn’t just random game playing.

Ma’am, I’m confused.

I don’t... If you’re so keen to smear a superior officer, you’re gonna have to be smarter than that, a lot smarter.

Now get out of my sight.

Go for a walk.

Do some serious thinking about your future in this department... in this service.

BENNY: Once we’ve posted a comment, his alert comes in on RSS feed on his laptop or his mobile.

As soon as he responds, I could trace his connection.

How did you do it?

How did I do what?

Guv, come on!

JOHN: No, DS Gray, you come on.

Was it you?

Did you do it for him?

Um, sorry, what he says, Erin, you lost me at hello.

JOHN: Erin, what is going on?

ERIN: "The creatures outside looked from pig to man, "and from man to pig, "and still it was impossible "to tell... which was which."

What was that about?

BENNY: Not sure.

I do know that Carroway had I.T.

crawl all over Schenk’s computer archives earlier.

Yeah?

BENNY: Yeah.

What do you think he’s been up to?

I don’t know.

I expect we’ll find out soon enough.

Right.

Let’s get started.

Type in "Hello."

Robert Millberry was arrested and taken into custody, in connection with two brutal attacks in London two days ago.

Police have refused to comment on reports that Robert Millberry escaped from custody today and is currently at large in the capital.

The story has appeared in several internet news sites, but no official report has yet been published by the metropolitan police.

Millberry allegedly escaped from a prisoner transfer van after overpowering a guard.

Fears are growing that there’s a link between Robert Millberry and the violent massacre that took place on a London underground station the night of his arrest.

I did it.

You did what, Justin?

JUSTIN: Hacked into the database, cleared all the history on Schenk’s computer.

So when Carroway went digging, there was nothing to find.

Oh.

She was only trying to do the right thing.

She doesn’t deserve to be punished for it.

It’s wrong.

JOHN: Yeah, it’s wrong.

JUSTIN: I need to make it right.

JOHN: Justin, I will.

Not you, me.

I did it.

So, I need to make it right.

( indistinct chatter ) Right, he’s answering.

He’s live.

JOHN: All right, Benny.

What we got?

BENNY: Just give me a moment.

He’s connected to the blog, I’m tracing his ISP.

Got him.

Aye, he’s at the Enspire Coffee Bar, Endymion Way.

MARTIN: John, we’re closer than you.

I’ll see you there.

JOHN: All right.

Gotcha!

JOHN: All right, what’s he saying?

He’s joking, he’s saying Robert should’ve stuck to the "no capture zone."

Benny is asking him what his next move is.

He’s typed S-E-A-L.

"Slaying everyone and laughing."

JOHN: Stay with him Benny.

What’s he saying now?

JUSTIN: Benny’s asking him to be more specific.

Okay, "Grinding Mobs."

So, he’s talking about a massacre.

( indistinct chatter ) JUSTIN: Boss, something’s wrong, he stopped responding.

Benny, we’re almost there.

( indistinct chatter ) ( tires screeching ) I don’t think he’s talking about knives and hammers, Guv.

He’s talking about carnage.

We’ve got to stand these men down.

MARTIN: It’s too late.

SHEPHERD ON MEGAPHONE: Nicholas Milberry.

Do not move.

Police marksmen have you in their sights.

Please stand, placing your hands slowly on your head.

He’s got something under his coat.

It’s not right, is it?

SHEPHERD: All right.

Stand down!

Hold your fire!

Hold fire!

Right.

That’s a dead man’s switch.

We take a shot, his hand loosens on the trigger, the vest detonates.

How big of a blast are we looking at?

SHEPHERD: Given the bulk of that vest, we’re looking at a hundred foot kill radius.

ERIN: Boss.

Setting up.

( helicopter blades whirring ) SHEPHERD: Assuming he maintains general bearing we need road blocks here, here, here.

We designate this area The Hot Zone.

Evacuate buildings outside The Hot Zone only, minimize bodies on the streets.

Clear a space, take him out.

Take him out?

What about the bomb?

We’re clearing the streets as best we can.

JOHN: What about the buildings?

I mean, look at all these buildings around here.

MARTIN: Everybody in the shops and offices inside this Hot Zone, they just fend for themselves?

SHEPHERD: Well, what’s the alternative, Martin?

Cross your fingers and hope he walks right out of London?

Much more likely, he’s got a target in mind.

They usually do.

Say, he’s en route to a hospital or planning to blow himself up in a primary school, what do we do then?

JOHN: If you shoot him, people die.

SHEPHERD: The question I have to live with is, how can I keep that number as small as possible?

MAN: ( indistinct ) MAN: Get out of here as fast as you can.

Move it.

No, leave it, leave it.

( helicopter blades whirring ) MARTIN: John, I can’t intervene.

It’s not my call and part of me thanks God that it’s not because I don’t know what I would do differently.

Look, um, whatever you got in mind, we got to do it quickly.

( helicopter blades whirring ) MAN: I got a shot, I got a shot.

MAN: All right, just stand down, watch the blast radius.

MAN: No, just keep moving him back.

Just move him back.

( helicopter blades whirring ) ERIN: What’s the plan then?

There is a plan, right?

( helicopter blades whirring ) Watch you.

I’m John.

Do you wanna play a game?

I already am.

JOHN: Oh, I know.

He’s wired.

Did he know he was wired?

What have you done?

JOHN: In order to get to the next level, you need a lot more points.

And correct me if I’m wrong, but you need a boss, I mean, to kill a boss.

Well, I’m the man at the end of that level, aren’t I?

I’m the man that’s chasing you.

I’m that boss.

If you beat me, you get to play on.

You’re gonna like this.

Check it out.

Now you roll the dice.

I guess the number, I beat you, you disarm that switch.

But if I lose... You’re not serious.

( John laughs ) Look at me.

Do I look like I’m joking?

Okay.

( helicopter blades whirring ) Let’s play in there.

( helicopter blades whirring ) Joe, those men are going to have to come down from that roof because they have to have a clear line of fire.

Joe, I need you to issue that order.

Bring five shooters down from the roof, make a perimeter around that truck and wait.

Have I just authorized the death of a police officer?

You know, I used to do this thing.

I used to-- I used to play Russian Roulette.

And why was that?

I don’t know.

I guess it’s because I was scared, you know.

I had control of my actions, but not the consequences of my actions.

Does that make any sense to you?

A few weeks ago, I realized that nobody can-- nobody can control that.

An action leads to a reaction that leads to a reaction, and it all becomes one chaotic system.

That’s why I can see how you and your brother made it simple, turned it into a game.

Right?

I can-- I can see that, makes sense to me, leave it to fate, to God, to a roll of the dice.

The rest of that fuel... on you.

I mean, it’s tiny in here.

Just do it.

Yeah.

Roll it.

Well, why don’t you put the detonator down?

Oh, no.

I can’t do that.

Yes, you can.

Listen to me.

You’re at that end, I’m at this end.

I’m covered in fuel and you have a lighter.

Okay.

Close your eyes.

Ready?

JOHN: Come on!

Okay, go.

One guess.

Are you scared?

No, I’m not scared.

Are you scared?

No.

So... what do you say?

What do you say?

All right.

Here’s what I say.

The A, between the L and R, aim low.

What?

You heard the man.

( guns firing ) ( helicopter blades whirring ) He hated the boy, but he wouldn’t kill him.

I want you to find him.

Find Frank and bring him to me.

No.

No, this is done.

We’re done.

That’s not for you to say.

You see, you made a mistake coming to me, ’cause I’m not Frank.

I never was Frank and I’ll never be Frank.

What are you then?

This is what I am.

Now, I spoke to a good friend of mine last night.

Now, if anything happens to Jenny, or anything happens to me, she is going to come for you with the wrath of God.

She’ll take whatever you’ve got left to love and make you regret the day you ever came across my path.

Are we done?

We’re done.

You didn’t really do that, did you?

Do what?

Like call up some totally psycho killer girl.

Her name’s Alice.

Whatever.

I don’t know.

What do you think?

I don’t know.

I do know you were totally epic though.

Totally.

So, now what?
