My, flatmate, she's sort of brilliant.

Would you like a whiskey with your coffee?

- Yeah. - I think I have some somewhere.

Hi. You all right?

Do you…

Do you usually work until 3:00 in the morning?

Different biorhythms.

You what?

I've changed my internal clock. I-I'm doing 21-hour days.

So… I-I don't… …I don't get it.

Term is eight weeks, 56 days.

It's not enough time for me to finish my thesis.

But if I make each day last 21 hours, then I get a whole extra week.

Right.

Means I end up eating breakfast when you're about to go to sleep.

I did warn you.

Okay. Well…

Yeah, good luck with whatever it is you're writing.

Proof of my theorem.

Right.

Night, Safiya.

I need your help.

Are you here alone?

My parents are away.

What happened? You okay?

Listen, I'm gonna need you to run to the store for me, okay?

- You don't want to go home? - I can't.

All right. …

Write me a list and I'll go.

It's bullshit. You're better than that, Safiya.

Hey. It's Stephen.

From the institute.

Just hear me out, will you?

You're a number theorist, right?

It's an important area for us.

Cryptography.

Genus theory.

Look, what happened to Robert Mallinder, it was a tragedy.

It was.

And with Ray Osborne's illness now progressing...

You know Osborne?

Edward, we're a research institute in Cambridge.

We know all the stars.

Past, present, future.

You're gonna need someone new to guide you.

We were rather hoping it might be us.

You won't find a more substantial endowment on either side of the Atlantic.

Kaplar Institute.

Privately funded.

Fostering talent.

Leave the world in a better place than we found it?

You can stay in Cambridge.

Finish your opus, whatever that may be.

We'll look after you.

Take all the time you need.

You got my card.

Come on.

- Soph. Please. - No. No. No, no.

Saf, you have been working on that ridiculous schedule of yours

for months now.

Come on. The work is over. We are celebrating.

Where's Mr. Mallinder?

- Robert has gone. - What do you mean gone?

Gone as in left me.

Gone as in it's over between us.

Bastard. Are you okay?

Yeah.

Is this it?

My finished thesis.

Is there any point in me trying to read this?

No.

What happened?

He didn't like my work.

No, seriously.

That's why.

He thinks I should just stop all of this primes nonsense

and he said that I shouldn't show it to anyone. Let alone publish it.

Why? Why would he do that? He loves you.

He wanted me to abandon it, but he knows I would never do that.

Thanks.

Pleasure.

- Yeah? - Alex, it's Taylah.

Taylah, where are you?

Just listen to me. The unit's been corrupted.

Someone killed Olson and they tried to kill me too.

Okay? It's got to be something that we've seen.

- Wait, T-Taylah... - Someone is wiping out our unit

and I need you to get me access to the files as soon as possible.

I need to know what's going on.

- Someone hacked our communications. - Taylah...

Okay? Someone must have been listening to us.

Hold on, someone's at the door.

No. Do… Alex, don't answer it. Just go around the back.

- Hello? - Alex!

Yeah, who… who are you guys?

I thought you'd want food.

- Real food, I mean. - Thanks.

I don't… I don't want to put you out though.

I, like you, Taylah.

I think you know that.

Yeah, I picked up on it.

Do you want to tell me what happened?

Maybe over a drink?

Yeah. Okay.

Wine?

- Sure. - Okay. Red? White?

Whatever you want.

Okay.

Some Pouilly-Fumé? What do you think?

Taylah?

How can someone like Safiya Zamil make such obvious errors?

Professor.

Safiya Zamil?

Do you remember? You… You gave me permission to look at her old papers.

Her rough work?

In case it would help me retrace my own workings.

The powers of three are never even.

Multiply an odd number by itself, the answer is always odd.

Of course.

Why has she put that the answer's two?

Well, exactly. And-And she's done it again here. Look.

"Two N-squared minus one is square. N equals six."

She's crossed out the right answer and altered it.

It's like… It's like she deliberately wanted it to be wrong.

It happens again, and again, and again.

It's… I made a list of all her mistakes.

A sequence?

I think so, but I can't find it.

Well, we'll just have to ask her.

What is it, Ed?

Safiya's dead, Professor.

A long time ago now.

She took her own life.

No.

But that's awful.

Awful.

Why?

Why, Edward?

… Move it up here.

Take a two.

Multiply.

- Six… - Saf, what…

- Six… - This is a solicitor's letter.

Sounds very threatening.

- What do they want from you? - What do you think?

They want my thesis.

They're not gonna have it.

Put it there. Or there. Yeah. Two.

- Two... - Is this thing playing up?

Why've you ripped the cover off?

- Hey, give me that. - Jesus.

Saf, what's wrong?

What are you trying to say, Safiya?

- Just writing shit. - Talking to yourself again?

Tragic.

My round?

Do you know, I think I'd rather just get out of here.

Okay.

I need to tell my dad about college.

Hey, if you take this money from the institute,

you can just tell him that instead.

"Yeah, I-I got kicked out of university

but it's okay because someone else wants to make me rich."

Yeah, he wouldn't care.

What?

Don't your parents want you to do well?

My mum did. But he

he's just always wanted me to be more like him.

We don't really communicate or connect.

He's not a bad guy. We just…

We don't intersect.

What about your mum?

She died when I was 16.

Jesus, Ed. I'm… I'm so sorry.

The universe is cruel.

Dad's got two boys now.

Decent kids.

Maybe he tried harder the second time.

They're watching me.

Following me.

Who?

Kaplar.

The people whose money you think I should take.

Dr. Nathoo?

- Hey. - Akram Nizar.

Baghdad Department of Culture and Antiquities.

Yeah.

Andrea said to expect you.

Yeah. Look, she sends her best.

Obviously she would have loved to be here. But…

Yeah.

- Tragedy for her. - Awful. Awful.

- Hey. - Hassan Kasem. Structural engineer.

Okay. So you're here to make sure the place doesn't fall down on top of us.

Well, I can't promise.

But… But yes, I'm here for everyone's safety.

- Okay. - Bogdan.

Head of security.

Right.

- Shall we? - Yeah, sure.

Follow me, please.

Doctor, watch your step.

You can leave it here.

So what do you think?

Magnificent, isn't it?

I have to tell Andrea. It's incredible.

Amen.

Amen.

Professor,

- would you like to slip along to the end… - Yes.

- So that I can invite… - Yes, of course.

Over here. Sit with me.

How about in English?

Horace.

Commending the brave.

I'm not sure, because…

Honestly, the madness of the act itself aside

there's not a moment since he died that I don't feel he was a mystery.

I mean, you weren't worried about him, were you?

Being a master of college, everyone assumes you're some sort of guru.

I'm as confused as everybody.

Sometimes there are no answers.

The dean was thinking of having a little college memorial service.

Not a wake, of course.

A celebration.

Well, it will have to wait until I'm back from Baghdad.

I love my work, James.

And this might actually be the House of Wisdom.

If I don't go see it for myself, I will end up a very bitter woman.

And none of us want that, do we?

No.

Of course not.

You know how much I admire your work. You must go.

Grab the bag.

- No! Get off me! - Give me the bag.

Hey. Look at that.

It could almost be an act of God.

The damage from the explosion, I mean.

If the explosion had been just inches from where it was,

the whole structure might have come down.

But here it is.

Almost untouched.

It's remarkable, really.

Yeah.

Perhaps it wanted to be found.

Nizar.

Do you wanna kiss?

Queerboy.

Hey.

Brave of you to come.

Well, it's brave of you to ask me.

You don't know what this meeting is about yet.

Something dangerous is happening.

What?

I need to show you something.

I don't know who to trust with this, but something is going on at the site.

Excuse me, but if you're not gonna drink, can you go and not drink somewhere else?

I'll get another one.

- Same again. - Yeah, sure.

Thanks.

So what have you tried? Differences, ratios?

It's okay.

Got it all right here.

You need to delete that.

I may.

- What's the work, Ed? - Don't call me Ed.

How do you know my name?

You'd be surprised with what I know.

Like, I know you got mugged the other night.

Now sit.

So what'd those guys take off you?

It wasn't money, was it? It wasn't your phone.

I need to know what work you're doing because that's what they wanted,

and that's what they took from you.

It wasn't my work they took.

Who are you?

The same people who came after you came after me.

They tried to kill me. So they're not playing around.

And until I work out what's going on, you're all I've got.

- Hey, I want to help you. - I don't need help.

Yes, you do.

Trust me, you do.

Now, what is this?

Whatever it is, it's valuable to someone.

- It's from a student. - Great.

- Do they have a name? - They're dead.

Well, are you sure it's math?

It's a sequence of numbers. Of course it's maths.

Well, can't a number just be a number?

Like, I don't know… Like a… a menu in a Chinese restaurant?

It's 11 digits long.

It could be a long menu.

Long menu.

- Thanks. - I'm coming with you.

There's our sequence.

Got it.

Dr. Nathoo.

Everything all right?

Well, actually, no.

No, I'm-I'm concerned about the stability of the site.

The department have signed off on it.

Right, okay. But, I mean, where is Hassan?

You know, where's… where is the structural engineer?

'Cause there's meant to be someone here at all times, so…

You know, I heard that there's been some disagreement

about the source of the explosion.

Okay, okay.

Doctor, you listen to me carefully.

If our assurances mean nothing to you, then perhaps you need to leave.

Then I'll follow up on this myself.

I-I'm-I'm looking for Hassan Kasem.

Do you speak English?

We work together.

My name's Charan.

The office gave me his address.

What do you want?

Well, I was hoping to speak to him. He didn't come to work yesterday.

He hasn't been here. I don't know where he is.

When he comes home, could you ask him… I… Sor…

There's nothing here. There's no notes. No clues, nothing.

What? Wait, let me see.

Not until you tell me what you do.

NSA.

The US National Security Agency.

Surveillance.

Bullshit.

Wait, so where have you looked?

Everywhere. The whole thing.

Okay.

That's her handwriting.

Whose?

Safiya Zamil.

The girl whose work those guys stole.

"Proof is the idol before whom we all kneel."

Proof is everything in life.

- "Proof that we are loved." - Proof that we are loved.

That we're desired.

"Needed."

"So here's mine."

Proof of what is happening

"to me."

What?

Is that a test?

I don't think so.

But… How often does that happen?

Never. Why?

Never is not good.

Let's go then.

Here. Take this.

Don't run.

Clear the building now, please.

…to rush.

Wait.

Look, I'm sorry, but you can't get in.

Let's go.

Sirs! Wait.

We've gotta split up.

Look, they only care about you. I'll circle back.

Go!

Okay, what's the work, Ed?

Your work that Robert Mallinder destroyed. What is it?

- You know about that? - Yes, I was watching.

That was my job at the NSA. To watch him.

Why?

We watch a lot of mathematicians. He was just one of them.

Ed, I think Robert's suicide was faked.

I think he was murdered.

When I reported it to my boss, he was killed and I just barely escaped.

So I'm gonna ask you again. What's the work?

Look, Ed, I'm the person that you tell.

Okay?

Help me figure this out.

Number patterns. Prime numbers.

Patterns in primes?

- That's what you're looking for? - Yeah.

My work's abstract. It's-It's pure mathematics.

Yeah, but coincidentally the-the

the cornerstone to all digital security.

You should know that if you, Safiya,

or anyone for that matter, found a pattern in the primes,

that they could crack any digital code.

Look, all digital locks are based on randomly selecting primes.

If you prove they're not random,

then do you know how valuable, how dangerous you become?

I'm talking about bank accounts, defense systems,

government records, classified reports.

Everything is left wide open. Nothing stays hidden.

So would that be such a bad thing?

You don't get out much, do you?

Look…

Taylah.

Taylah, whatever. A-A prime finder.

A ru… A rule for finding primes. It's a theory.

Like capturing sunlight, it's not meant to be possible.

But you think you found a way?

That Safiya found a way?

I don't know. I don't know. Maybe.

I can't know for sure until I see her thesis.

What else was in the book?

"Cambridge doesn't feel safe anymore."

- "I am surrounded by a kind of…" - …a kind of dark geometry.

- Saf! - Hello! Safiya.

Something that I thought was impossible,

might actually be possible.

If you're reading this, then what I feared most has happened.

And although it's too late for me, you must

- shine a light on what's going on. - "…a light on what's going on."

It's an abstract. It's a summary of her thesis.

And?

And it's the exact same area as mine.

What's this?

Kaplar Institute.

It's a research institute in Cambridge.

They asked me to join, but…

But… Ed, what?

Her work could be there!

I don't want any part of this.

No, Ed. Kaplar could be our key.

Don't you see?

It's the only way we figure all of this out.
