Original subtitles

I have information about a major KGB operation.

- It has been named Operation Glass. JOE: - Who's the first agent?

ARKADY: David Hexton.

David, this is an opportunity to be a hero.

- SARAH: - This isn't a conventional war, Jim.

Do the Soviets want to oppress us? Without question!

How are you given the names?

A dead letter drop.

In men's toilets. They put adverts in classified ads.

They say, "Cousin Andrew, please visit us."

If Moscow know he's working for us, it'll be a trap.

- They'll be waiting for him. - Daddy, we need a decision.

DADDY: We assume Moscow don't know about Arkady.

We let Arkady collect the next name.

We endanger the few...

to protect the many.

BIRDS CAW

ARKADY: It could be a trap.

What if they are waiting for me?

What if they shoot me?

Well, that's why I'm here.

Then, I can arrest them.

What?

I'll take up position.

Wait five minutes, then head for the drop.

DRIPPING WATER

What happened?

Sex.

He wanted sex, Joe.

Well, I can always come back later.

LAUGHS

SIGHS

Yeah, this time he was no-one.

- Every conversation we have... - IMITATES GUNSHOT

- Every name I give you... - IMITATES GUNSHOT

We'll protect you.

Is that what you told David Hexton?

I told him it was his chance to be a soldier.

To be a hero.

My father fought in Stalingrad.

He was awarded the Order of the Red Banner.

That was a war that made heroes. Not this.

Would our fathers be proud of us, Joe?

I don't know. My father's dead.

Look, remember what you said -

if Operation Glass is successful, it changes everything.

All the horrors you've seen in your own country,

they'll bring those here.

I don't care about any of that.

And I don't think you do, either.

We join the game for different reasons.

And whether you stay loyal or you betray everything,

only you know why.

So, whatever made you join us in the first place...

..just remember that.

Come on.

BOBBY ON TAPE: I'm worried about Daddy. One more cock-up,

he'll be getting his clock, which will be heartbreaking, blah-blah,

but maybe a blessing. I mean...

the business with the Chinese dancer?

Someone has to mind the shop,

the old man is losing his grip...

As requested, all meetings are recorded for your...reference.

We must have caught this conversation

- by accident, before the tape was stopped. - Has anyone else heard this?

I brought it straight to you.

Bobby Waterhouse.

He really is the limit!

I'm sorry, but I make no apology for my language.

Bobby is who Bobby is.

Thank you, Alan, for bringing this to my attention.

We will say no more about it.

See you on the green.

ENGINE STARTS

SHE SIGHS

What's your name?

Tom.

I'm Alice.

Hey...

We're going to be friends, aren't we?

DADDY: We're getting ahead of ourselves. Who is this man?

Thomas Mallory. Graduated from the Royal Naval College, '44.

Six years on HMS Pioneer,

seven on HMS Eagle, rising to lieutenant.

Desk job at the MoD ever since.

And the message Arkady is to give him?

Arkady has deciphered his instructions with his one-time pad.

He is to greet Tom and hand over the message.

It's merely a name and a phone number.

Valerie Parkwood. 0-1-9-4-6-4-9-8-0.

Who is Valerie Parkwood?

She's, um...

- Secretary to the Prime Minister, Daddy. - Good God!

You don't think she's got snow on her boots, too?

Anyone with that level of access

would have been thoroughly vetted, but we can't rule it out.

It could be that Mallory's task was to reactivate her.

Well, then why not have Arkady contact her directly?

Information about Operation Glass

is released on a need-to-know basis. Why involve someone else?

We'll monitor Tom Mallory from the moment of reactivation,

follow him to Valerie Parkwood and see what they're cooking up.

But that brings us back to our problem.

Tom Mallory is in police custody.

He was arrested last night for beating up a prostitute.

Now, this is something of a habit with him.

But the last three times, he's wangled an acquittal

or it never got to court.

On this occasion, however, the victim

- is determined to press charges. - Sarah, I want you running things.

Use Joe for all face to face.

Sarah? But I was rather hoping...

Alan, we need to put ears in Valerie Parkwood's flat

and on her work telephone.

Um, Whitehall get rather touchy about us tapping their phones.

I'll talk to the Cabinet Secretary.

Joe, return this to Arkady,

let him reactivate Tom Mallory.

Bobby, call the Police Commissioner, get Mallory released on bail.

He can't teach us much about Operation Glass

from inside a police cell.

This is our chance to make amends

for what happened to David Hexton.

No-one else is going to die today.

DOOR CLOSES

Daddy, sorry, quick word. Um...

I'm a little piqued,

truth be told.

I'm the most senior Cub Scout here,

but you're giving Sarah the keys to the hut.

People are talking, Bobby.

They say, "Old Waterhouse? He's a confirmed bachelor,"

and then they wink and they snigger,

and I'm sure I've even seen a nudge in the past.

Do you know what I take that to mean?

SWALLOWS HARD

I can't imagine.

Work can only ever be a mistress, Bobby.

Mistresses are ravenous.

But a wife puts the world in perspective, makes a fellow rounded.

I bet your mother is desperate for grandchildren.

Well, you've met my mother, haven't you?

Asking you to be selfless is futile,

only an enforced separation will suffice.

I want you to take a more observational role.

Giving you space to find yourself...

..and perhaps...someone else?

But, Daddy, my duty is to the job, to you.

Be assured, I know exactly...

..where your loyalties lie.

Very good, Daddy.

Mr Mallory, I bring greetings from your aunt in Somerset.

What?

I don't have an aunt in...

My aunt?

Well, well, well.

How is the old girl?

Arkady has reactivated Tom Mallory.

We'll wait for him to make contact with Valerie Parkwood

- and see where that leads us. - I'll speak to the prostitute,

get her to drop the charges. Last thing we need is a pending court case

when we're trying to keep him under surveillance.

What?

You.

You're you again.

The agent that was killed in Poland,

the man that killed her, is part of Operation Glass.

He's the man that killed David Hexton.

His code name's Odin.

You've known about this since David Hexton died? Christ, Joe!

This is a major conflict of interest.

- You don't think you should have told us? - How a conflict?

How? We're engaged in a delicate, volatile operation

and you're pursuing a vendetta.

It's the same objective. Find Odin, expose Glass.

Expose Glass, find Odin.

They may be the same objective now, but what, if suddenly, it's not?

How do I know you'll do your job...

instead of pursuing some ridiculous quest for vengeance?

Sarah, please! Let me do this.

I told her I'd look after her.

- YULIA: - What's that?

It's chalk.

- What does it do? - What does it do?

It's chalk.

What does chalk do in Russia?

It's not secret spy chalk?

Oh...I don't think so.

I bought it in WH Smith.

Hmm.

This is how we're going to communicate.

This...this says there's a message in the dead letter drop.

Under the last bench, the last pew of St John's Church.

- Right. - Mm.

If you've left a message there,

you draw a line...here.

If you've picked up that message,

or if I have, you draw another line here.

What will the messages be?

I don't know. It could be anything.

What if you just want to say hello?

Yeah, we don't usually, um...

Look, any messages...

What if I want to recommend a book?

I promise I only use for really good books.

Yulia, this is serious.

I know this is serious.

But you can smile.

You are allowed to enjoy things.

One more signal.

What's that?

Danger.

This means you're in danger.

Alice?

Sorry to bother you. My name is Tim Dawson.

I work for the Government.

I'd like to talk to you about the man who assaulted you.

Wondered when you'd show up.

It would be very beneficial to us if you could drop the charges

against him. I can't give you the details why,

but we need to keep him under surveillance.

SHE SNIFFS

- No. - That isn't to say you

wouldn't be compensated for what you've suffered.

I'd like to give you £150...

I was thinking about it afterwards, I was thinking...

"It won't be easy, Alice.

"He's posh, they won't like it."

- And here you are. - He's part of a process. It is for the good

of the country he remains at liberty, so we can monitor him.

It's nothing to do with class.

Of course, it is.

Everything is.

If I carry on...

If I press charges, what will happen? To me?

- Will you lock me up? - Steps would have to be taken.

SHE SCOFFS

For the good of the country, you say.

Just who are you protecting?

Cos you ain't protecting me.

WOMAN: The top copy goes to the Cabinet Secretary,

the bottom copy goes to me.

Why does this very simple concept continue to elude you?

'Valerie, it's Tom. Tom Mallory.'

Goodness, it's been a while.

Yes, sorry about that.

Something... Something came up.

All very hush-hush, you know how it is.

Erm...

But a day didn't go by that I...

I didn't think of you.

'And...'

'..I was wondering, if we might,

'um, get reacquainted.'

In fact, looking at the old...diary,

I... Yes!

I'm free this evening.

I could pop over? Seven o'clock all right?

VALERIE: 'Well, I...

'suppose I could...

'move a few things around...'

'Well, that's lovely. Listen, must dash. Ta-ta.'

Sarah's gone slightly overboard on the provisions.

I think it's her way of saying you look undernourished.

Um, we're trying to get pregnant,

RECORDER CLACKS

Curtain up.

Hello.

Sit down.

One of the duties of each new Prime Minister...

..is to write a letter of last resort.

It states his decision about whether to retaliate,

in the event of a nuclear strike.

You typed that letter for him, Valerie.

'You know what it says.'

- 'Now you're going to tell me.' - 'How can you ask such a thing?'

This is treason, Tom!

Valerie, Valerie...

ours is not to reason why...

No, Tom.

This will not do. Get out.

Get out of my flat, this minute.

And here was me thinking...

..you were the decent sort.

We can't let him access that information.

We'll lose our advantage. He'll know we're onto him.

She's resisting him. She's not telling him anything.

- VALERIE: - It said...

I was really surprised by this.

It said...

"Piss off, Tom."

- TOM: - 'I had a feeling you'd be like this.

'Luckily, I came prepared.

'Take a seat.'

# TCHAIKOVSKY: Pas De Deux from The Sleeping Beauty

I thought my work would be a privilege.

I thought I would spend my days

in the company of...

gallant and charming men.

But instead, we shovel shit.

And when we get home,

our clothes are stiff with...

blood and sweat and grease.

I miss the war.

The other one.

A chap knew where he stood.

- SARAH: - Why didn't we have someone stationed outside?

- JOE: - For all we knew, it was just a standard reactivation.

There was nothing to make us think that...

So?! Where is he now?

We don't know. We've searched his house, there's nothing.

Let's not panic just yet. What's in the letter?

If the Prime Minister says we'll retaliate,

the stalemate remains intact. It doesn't matter if they know.

Valerie said it's no.

No strike back.

No retaliation.

So, this is it.

My God.

Operation Glass is a pre-emptive nuclear strike on the UK.

Sorry, can we just go back a bit?

The Prime Minister said no?

That, if they attack us, we won't fight back?

Are you serious?

Right, so, we're completely vulnerable.

Everything you... The whole bloody Cold War,

everything, it's nothing! It's...it's bluff!

Which is why that information cannot be allowed to reach Moscow.

Well, Mallory's only point of contact with Moscow is Arkady,

so for the time being, it's contained.

But Arkady wasn't recruiting Tom, he was reactivating him.

He must have been working with someone before.

He could have contacts, handlers, safe houses,

an entire network from back then.

Bobby's right, we need to move on this quickly. Tonight.

If Tom's already passed the information to Moscow, they could

be preparing an attack now.

Bobby, I want you monitoring the situation overnight.

Open lines with 6,

the FO, the MOD.

The Red Army start amassing on borders,

residents start packing, I want to know.

- Well, if you think I'm up to it! - I could help.

I mean, I don't mind. Extra pair of hands and all that.

What do we do about Tom?

Until we hear otherwise, we assume he's still in the country.

We find him, question him.

The time to protect our advantage is past. We need to get him

- and that intel out of circulation. - Interview the prostitute again.

Perhaps Tom mentioned somewhere he was going.

Speak to her, Joe.

Tell her what she needs to hear.

- SARAH: - Thank you, everyone.

Daddy, Bobby, can I have a quick word?

Even if we find Tom before he hands over the intel,

even if we put him in prison,

such a simple piece of information to pass on...

I wouldn't be doing my job if I don't suggest we prepare

- a couple of contingency plans. - Agreed.

But I need to know how absolute you want these plans to be.

Tom Mallory cannot be allowed to contact Moscow.

Your list of options should be comprehensive.

Brief Joe accordingly.

I want him prepared...in every sense.

HE EXHALES

- JOE: - The man who assaulted you has gone missing.

Did he talk about someone? Did he mention any trips he had planned?

If you still want to press charges,

we would now be in a position to help you.

If we could locate him, entice him here, then we could...

- You'd bring him here? - He wouldn't expect us to be here,

then we could arrest him.

He left this.

It's a private club on Piccadilly.

Just a posh strip club, really,

but he wouldn't have this, unless he was a member.

Alice, this is great, thank you. But I've got one more favour to ask.

Go to the club, tell them you've been contacted by two Russians.

They want the information that he got from Valerie Parkwood.

They'll meet him here tonight, at 11 o'clock.

Hi, I'm looking for one of your members. He's Tom Mallory.

- Yeah, lovely. - Can you make sure he gets it? - No problem. - Thanks. - Thanks.

Soviet tanks are carrying out manoeuvres along the Finnish border.

This is a monthly event, so probably nothing to worry about.

And the embassy residents?

We've placed all but five, but the outstanding ones are low level,

so not the sort to be smuggled out first, as a matter of priority.

Should we tell them?

It feels wrong, us knowing

what's about to happen

and not them.

No. I know it's hard, but we can't.

Daddy's just promoted me,

so it would be absolutely rotten luck if it was the end of the world.

Daddy's promoted you?

I'm assistant to his permanent secretary.

No, hang on, that's a political thing, isn't it?

I'm assistant to his permanent secretar...

- Oh, I said it again! - When did this happen? - Yesterday.

I'm just mucking in, while Joyce has her baby. You know,

I'm not sure I even get a rise, just some Luncheon Vouchers,

but I'm jolly thrilled.

Least surprising thing I've heard all day.

But if this is close of play, should I call anyone?

I wouldn't tell them anything, obviously.

I just want to hear their voices.

My little brother,

my nana.

Well, I'm sure they'd be very happy to hear from you.

Because of the threat of radiation,

you and your family may need to live in the fallout room

So, you must make it as safe as you can

and equip it for your survival.

If you are at work, or elsewhere, and cannot reach home

If a death occurs while you're confined to the fallout room,

place the body in another room and cover it as securely as possible.

We'll go ourselves.

What? We can't do that! He's a protected source.

Besides, I want Joe interrogating Tom Mallory.

Please!

This is so important, it's so terrifying.

Moscow want to meet Tom tomorrow morning,

Grand Union Canal, under the Westway at 6am.

If Moscow are still passing messages to Tom through Arkady,

that would suggest they don't know where he is either.

And that they don't have the intel.

Good, but we still need to decide what to do with him

when he turns up here. If he turns up here.

We'll question him.

Find out everything he knows about Glass.

Then what? He still has the intel.

We can't let him out of our sight.

Throw him in prison or throw him in the Thames, I say.

Either way, Moscow will know that we're onto him.

- We'll lose our advantage. - Well, better that than them finding out

we've got our knickers permanently round our ankles! Come along, Wendy.

What did you tell Alice?

She might ask me. We need to be consistent.

I told her we'd help her press charges.

What will you say when she realises we can't?

I don't know.

Lie to her.

I've got pretty good at that.

This isn't about... No, no!

This is not something like that.

I just thought it would be pleasant.

No, no, it would.

But...it's awkward.

This would cost you nothing. But for me...

You can't court your boss and expect people to respect you.

So, we have to choose.

Well, at least I do.

And I choose work.

- You're ambitious. - That's not a crime.

No.

No, it certainly is not.

Let me make amends. Now, you're having trouble with your flat.

Well, there's a room going in my house.

It's just me and the mother-ship there,

rattling around and she's a...sweet, gentle old soul.

That's very kind, but doesn't it leave us with the same problem?

A single chap and a single girl lodging together,

people will talk.

Oh, I'm sure they won't.

So...

This is what we know, Tom.

You've been spying for the Soviet Union,

and through violence and coercion,

you managed to obtain the contents of the letter of last resort

from Valerie Parkwood.

Now, that, right there, is life in prison.

Now, people in prison for treason,

they exist outside of the legal system.

It's...

endless.

It's maddening.

You'll wish you'd never been born.

You'd be amazed at the rumours that start up

about prisoners in solitary...

..that they killed their own children and molested the bodies.

How fast can you run?

Tom, is the Soviet Union planning a pre-emptive nuclear strike?

Or is the letter of last resort part of a bigger operation, then?

You like it rough, yeah?

Yes, Tom.

The rougher the better.

How will Moscow use the contents of that letter?

HE CHUCKLES

Mm, you look the sort.

I bet we'd have an absolute scream.

I'm happily married, thank you,

but it's nice to know one can still turn heads.

Answer the question.

Do you know what the comrades have promised me for helping them?

A statue in Gorky Park,

a national holiday in my name...

..and a procession of pliant, yet motherless, girls

who bruise easily...

..but don't fight back.

All that's null and void if I cooperate with you.

Jim, can you step in a moment?

- Give me your belt. - What are you...what are you doing?

The light fitting's not strong enough, but there's a decent drop

from the banisters, so we'll use the stairwell.

What...what are you doing?

Well, the official version will be

that you came here to plead with Alice to drop the charges.

She refused and fled.

You couldn't deal with the inevitable disgrace,

so you decided to take your own life. Jim, will you get his legs?

Get his legs.

No, no, no, no, no, no! Christ! Christ, no, stop!

Christ, stop!

God! All right! All right! All right, all right, I'll talk!

I'll talk!

HE GROANS

Shall we start again?

Who have you told about the letter of last resort?

No-one.

Before you were approached the other day, when was the last time

- you had any contact with Moscow? - About a year ago. - Why so long?

They were putting a lot of their UK networks on ice.

They had an idea, they said...

..for something,

um, but they needed to get certain things...

in place first.

I don't know... People, I think.

Who told you this?

It was a phone call.

Someone I hadn't dealt with before.

He told me to imagine a constellation of stars.

The axis had to shift slightly and...

..stars had to be lined up in a certain way

- before they could proceed. - What was his name?

They don't trade in real names any more than you do.

He told me he was called Odin.

SARAH: The letter of last resort...

is that the endgame?

I don't know.

Look, I mean, I really...

I really... I don't know!

They haven't told me.

The information you were given was just a name and a telephone number.

If you'd had no contact with Moscow, how did you know what to do?

The last task they gave me, before it went quiet,

was to get the letter of last resort from Valerie.

I sought her out, I screwed her...

They told me to stand down.

- How did they recruit you? - They said Britain didn't appreciate me.

TOM LAUGHS

Said warming a seat at the MOD was a...

criminal waste of my skills and intellect.

So, this isn't about an ideology, this is about...

..recognition.

I won't get so much as a bloody MBE from you lot.

Christ, they give those to lollipop ladies now!

So, if we made you a better offer...

..you'd consider coming back on side?

- What? - What?

- What? - What?

Well, not threatening to kill me would be a start.

Come and work for us and you'd be surprised how generous we can be.

Jim, will you pop in for a moment?

In return, all you have to do is meet with the Soviets

and gather intelligence on the wider operation and on Odin.

Step outside.

Now.

He can't contact the Soviets.

He'll tell them about the letter, they'll attack straight away.

Arkady said the history of counterintelligence

will be split into before and after Operation Glass.

That, to me, suggests a sequence of events,

- not just bombs flattening London. - Then why did they want the letter?

Well, wouldn't we? If they had an equivalent? It's just a fail-safe

in case the wider operation goes wrong.

They went to a hell of a lot of trouble for a fail-safe.

Christ, I said this would happen! You are putting your personal agenda

- ahead of the mission. - It has nothing to do...

Look,

if we arrest him, if we silence him and throw him in prison,

Moscow will know that we're onto them.

They'll retreat into the shadows,

the operation will still go ahead as planned,

but it'll be too late for us to know anything about it.

Look, Tom will be wired, we'll have shadows on him. OK?

We won't let him out of our sight. Please, Sarah...

..let me do this.

He can lead us to the heart of it,

then he can lead me to Odin.

SARAH: And if you're wrong? If he tries to escape?

Then I know what I have to do.

- OVER RADIO: - The bridge is covered.

I just need to test the levels. Could you say something?

You...have...

egg...on...your...tie.

JIM OVER RADIO: I'm in position. Over.

Right, it's time. Whatever it said in that letter, you tell them

that the plan is that the UK would retaliate.

FOOTSTEPS

CRACKLING

Joe, make sure it's pointed at Mr Mallory.

DOG PANTS

All right?

I think he's spotted someone.

OK, curtain up.

All units, stand by.

'They know everything.'

Shit!

Hey!

Jim, watch the door.

You, check there's no other way out.

Don't come inside.

Joe?

I've got a family.

You can't trust him.

Do what you have to do.

GRUNTING AND GASPING

GROANS

Please!

I'm unarmed.

Turn around.

HE GASPS

Please...

You're better than this!

Apparently not.

Close your eyes.

HE HYPERVENTILATES

I've met Odin.

CONTINUES GASPING

I met him. Last year.

I can tell you everything you need to know.

What's his real name?

Why is he here?

Come on,

let's not rush things.

Hmm? I tell you all that,

you won't need me any more.

No, let's think of this

as the beginning of our relationship.

Hmm?

HE PANTS

How can I trust you?

Double-crossing you was a mistake,

I can see that now.

But we're starting again.

Hmm? Next time, I'll lead you right to the man himself.

And the letter of last resort?

Oh, don't worry about that.

My lips are sealed.

Scout's honour.

You've got a thing going with Odin, haven't you?

I bet there's a woman involved somewhere.

Don't worry, I won't pry.

But what do you say?

You scratch my back?

Hmm?

(It'll be our little secret.)

That's the ticket.

GUNSHOT

- ECHOING: - You've got a thing going with Odin, haven't you?

I bet there's a woman involved somewhere.

INAUDIBLE

- BOBBY: - Kate Wilkinson, 36, unmarried, no living relatives.

Arkady's message meant something to Kate.

It triggered a new stage in the operation.

- JIM: - What makes a girl like that turn on her country?

She's so...normal looking.

If we don't secure her tonight, it's over.

- She's doing a runner. - DADDY: Turn her double agent, Joe.

Talk to her, charm her.

Whatever it is you do to them.
