The evidence we have found suggests

that Daniel Hodge
was not killed in Baltegrad.

It was Shen Jia
and a male accomplice...

So she's our suspect? Mm-hm.

I want to show you something.

One of our men took the footage of
the event with a night-vision
camera.

I don't know who that is.

Get me everything you can find
on Mark Cunningham.

GUNSHOT

The Minister for Energy
and Green Transition

has been kidnapped by a man
named Jason Collyer.

He's a very dangerous individual.

The Government has got 24 hours
to publish the truth

about what
they are already doing on Svalbard.

Miss the deadline
and I'll shoot him.

What's Jason done?

He planted a bomb at the university.

Jason is wanted for kidnap
and murder.

Jason's girlfriend is on the move.

Track my location and send a team.

Did you leak details
of your mission to the Russians?

My God - I'm not a traitor,
I'm her boyfriend.

The professor withdrew his support
for the seabed mining

after coming here. Oh, God.

We know there are questions
about the report.

We found traces of explosives
on your sweatshirt.

Chloe...

I saw who moved the man's body.

I saw their face. Very clear.

Under no circumstances
do you leave this room.

They told me no-one would get hurt.

I never meant for this to happen.
Chloe, no!

GUNSHOT

She's been stabbed.

ALARM BLARES

She's dead.

Kirsten, why is she here?

I...

I don't know.

Right, we need to secure the scene
for forensics.

You need to bag that.

Right, everybody needs to leave.

Right, OK, nobody
touch anything. OK?

OK. Come on, let's go.
Out of my way.

Out of my way!

What has happened here?

I don't know.

We...

She was already dead
when we got here.

She shouldn't even be here.

I know.

Korotayev sent me here...

...and he said you had taken her.

Is that true?

Yes, but...

I...

I didn't have anything to do
with this.

I mean, I couldn't have.

You were with me when we found her.

Come on. Director, I didn't do this!

Then why is she here?

Come on. Let's go. Please.

This area needs securing
for forensics.

Come on.

Thanks.

Will she live?

It's too soon to say.

Listen, erm...

We should, er...

You know, we should talk about
what was said in there.

It's not me you have to
explain it to, Minister.

Excuse me.

This DI Kirsten Longacre,
please leave a message.

Hey, love.
Can you call me when you get this?

This doesn't look good.

Another Russian killed.

I can't have murdered Polina.

I was with the director.

Doesn't mean that you weren't part
of a conspiracy to murder her.

You brought her here.
Yeah, because she asked me to.

Polina was scared.

When I was leaving Baltegrad,
she asked - she begged me to...

Begged you? Yeah, she begged me
to bring her back here.

She wanted asylum to the UK

in return for what
she knew about Hodge's killer.

It's not the first time someone has
tried to defect on Svalbard.

Who else knew she was here?

Just my superior back in Scotland.

Who could have told
the British soldiers.

See, why would I want Polina dead?
Hmm?

Why? That's for an investigation
to find.

Can we keep this to ourselves
until then?

I'm afraid it's too late for that.

What do you mean?

Korotayev already informed Moscow
about the situation.

And they insist he deals with this
matter personally.

And they demand you arrest
DI Longacre, now.

♪ Do you want me on your mind?

♪ Or do you want me to go on?

♪ I might be yours, as sure
as I can say

♪ Be gone, be far away

♪ Oo-o-o-oh

♪ Oo-o-o-oh, o-o-o-oh

♪ Mm, mm, mm. ♪

So, Jason's in a cell downstairs.

His lawyer's on the way.

What's going to happen
to the minister?

He's writing his resignation
letter as we speak.

I'm not sure what I'm going to
say to his wife.

Did you know that he was covering up
the seabed mining report?

No, of course not.

It's not in our remit to
investigate our own government.

Maybe it should be.

Gordon has been championing
environmental issues

since he was on a backbencher.

I never thought he'd
compromise on that.

I think there's cause for a criminal
investigation here.

You may be right.

But not until after there's been
a full Parliamentary inquiry.

PHONE VIBRATES

Excuse me.

What's the update on Chloe?

She's stable.

The doctors are keeping her
in a coma until the swelling...

Well, to see IF
the swelling reduces.

They had to take that shot, Amy.

I had it under control.

You were a hostage.

She planted a bomb
that nearly killed you.

That did kill someone else.

Chloe said she didn't want to
hurt anyone.

There's no motive for her
to blow up the lab.

Not with Vincent and Jason in it.

Yet she had explosive
residue on her clothes.

I think that Chloe was manipulated

into putting that bomb
into Jason's bag.

She was trying to tell us
that someone had got to her.

Who?

I don't know,

but it's got to be connected with
what's happening on Svalbard.

OK. We'll start going through
her phone, her emails...

Our analysts can help.

If you're right, we'll find them.

Thank you.

What is it?

There's a situation on Svalbard.

It involves Kirsten.

Is Mum all right?

Yeah, she's not hurt or anything
like that, it's...

It's just something went wrong
with work, and...

Well, now she can't leave.

And you're going over
there to sort it?

Yeah.

I'll only be gone a few days,

and your granny's here.

Too big for hug?

Never.

Hey, don't worry.

I'm going to bring Kirsten home.
I promise.

DCI Silva.

Welcome to Svalbard.

You didn't have to come and get me,
Director.

Unfortunately, we don't have a
lot of time

before the Russians
arrive at the hub, and...

...it would be good for us
to talk alone.

You're walking into a bit
of a bear pit.

It's that bad?

Keeping the peace
has to be priority.

If only Kirsten had come to me
before going to Baltegrad, then...

How is she?

As good as can be expected.

I had to confine her to her room to
stop the Russians from complaining.

They've been waiting
for an opportunity like this.

Before the invasion of Ukraine,

Putin claimed Russians were
being killed in the Donbas.

12 years before that, he said
the same thing about Georgia

and sent troops in.

He won't have to lie this time.

You think they'd go to war
over this?

Well, we can't let it get to that.

I mean, if Russia were to
try anything,

then NATO would respond, and, er...

This needs to stay a police matter.

What are you doing to find
the killer?

Well, I've locked down the hub,

so whoever it is will still
be in there,

and my team are establishing
everyone's alibis.

Will I be allowed to investigate?

No. Officially, you're only here

so the Russians can have someone
else to shout at.

And unofficially?

Between us...

...my superiors are happy for your
DI to take the fall

if it'll keep the peace.

Take the fall? She hasn't
done anything illegal. I know.

I know, but if the Russians can't
get her on conspiracy to murder,

they'll... push for kidnap
or false imprisonment.

It could get ugly.

I'll...

I'll buy you some time,

but we need to find
Polina's killer soon.

KNOCK AT DOOR

DOOR OPENS

Amy! DI Longacre.

I have a few things to finalise
before the Russians arrive.

Can I leave you to it? Of course.

Oh, God...

Oh...

God, you took your time.

I missed you too.

How are you?

Never better.

I'm surprised they sent you.

Sir Ian had to pull
a lot of strings.

See, what happened wasn't my fault.
I know...

OK? I did everything
I was supposed to. I know.

Just...

Tell me everything that happened.

The Russians are here -

and it looks like
they've come mob handed.

I don't like it.
They're up to something.

Are the comms ready?

Yeah, Anderson's got 'em.

He's just finishing up
the surveillance.

We stay alert,
but keep a low profile.

We don't break cover
until we have to.

You got your priorities straight?

I need you focused.

You can rely on me, boss.

And that was the last time
you saw Polina? Yeah.

I was gone less than an hour.

You locked the door
when you left her in here?

No. No, I rolled out the red carpet.

It's just that there's no
sign of forced entry -

and if you'd forgotten...

No, I didn't forget.

Polina was the key witness
in the Hodge case.

So, whoever killed her might have
been trying to silence her?

Just how... how did they know
that she was here?

I don't know.

I made sure no-one saw me
bring her in.

OK.

I'm going to sort this, OK?

KNOCK AT DOOR

I'm sorry,
but the Russians are already here.

Stop here.

Arms like this.

Is this really necessary, Director?

Mayor, this is DCI Silva.

I know who she is.

It's good to meet you.

I wish it was under better
circumstances.

If circumstances were better,
we would not be meeting.

Can we get started?

I'm afraid your men will have
to stay here.

Fine.

HE SPEAKS RUSSIAN

Follow me. Follow me.

Watch them like a hawk.

Yeah.

If anybody comes in or out,
we'll know.

DOOR OPENS

What is she doing here?

This was all agreed.

But it is her we are here
to talk about.

Please.

Sit.

HE CLEARS HIS THROAT

DCI Silva, perhaps you could...

Sure.
But I'd like to say something first.

I know how it looks,
me bringing Polina back here...

...but yesterday,
you called the director

and told him
that I had her in my room.

How did you know that?

I am not here to answer
your questions.

Because this isn't the first time
someone's leaked information to you.

Someone told you about Shen Jia
leaving, as well.

Presumably that came from FSB
intelligence?

Presume what you want.

We need to know who's spying
in this hub.

Are you trying to blame
Polina's death on us?

Director, we need a full
investigation

to establish the facts
of Polina's murder.

I agree.

Colonel Zamorin should be
the one to carry it out.

You know I can't allow that.

Why not?

People from 40 different countries
live in this institute.

And, with respect,
Russia's reputation is not the best.

If I were to give free rein,
then there would be a riot.

My hands are tied.

I understand,
that you're suspicious,

and, although we disagree
on her motives,

my DI was wrong to bring
Polina back here.

But that's not what killed her.

I think we all want the same thing

here - which is to find out whoever
did.

What do you propose?

Well, given the circumstances,

I think it makes sense
that the investigation

is to be led by the Russian police -

but, for the residents of the hub
to accept it,

I assume it needs to look like an
international investigation.

Which is where I can help.

You want to investigate
your own officer?

Well, Colonel Zamorin
will be in charge,

but I'll... observe,

advise.

I'll work with him, not against him.

Of course, there would have to be
a Norwegian officer on the team.

This is our jurisdiction.

OK.

But I'll remain in the hub while
my officer goes about his duties...

We're all agreed. DCI Silva
can shadow the investigation.

In a cold storage room at the far
end of the hub,

Colonel Zamorin will meet you there,
along with my Deputy, Olsdatter.

I need to update Oslo.

I didn't mean what I said in there.
I know.

It's just what they need to hear.
I know.

Stay in your room
until I sort this out.

Jesus!

Oh, Cunningham?

Sorry.

I didn't mean to scare you.

Yeah, well,
you did a shit job at that.

What are you doing here?

The last time I saw you,
you disappeared.

Now there's a dead
Russian in the hub.

I just want to find out
what's going on.

The investigation's ongoing -

and I'm not at liberty to share
anything more with you.

I have been ordered to stay here
in my room, until it's over.

Hodge's killer still
hasn't been found,

and the longer Jia's
out there on her own,

the less chance I've got
of finding her alive.

But if I'm going to help her, I need
to know why the Russians want her.

Is it something Jia was working on?

She wouldn't talk to me about that.

I'm not a scientist.

Right. Well, then I need
to speak to one.

I thought you were to stay here?

I'm here to do a job.
I'm going to see it through.

You can go now.

MUFFLED CHATTER

KNOCK AT DOOR

Do you mind if I come in?

Hi. Hello.

I am Deputy Olsdatter. DCI Silva.

Please. Thanks.

OK.

Ready to observe and advise?

Because of the situation,
a full autopsy was not possible.

But it is clear that she was killed
with one stab wound.

Which you see five, maybe six
centimetres above the navel.

Was the murder weapon found?

Yes.

Right next to her.

The killer was clever
not to leave any prints.

The only ones on it are Polina's,

from when she must have
pulled it out.

There's no defensive wounds
on the hands and arms.

She didn't have time to
defend herself.

There is only one stab wound.

From the position, I'm guessing
the aorta was punctured.

It would explain why she bled out
so quickly.

But to hit the aorta
with only one attempt...

The killer got lucky.

Or highly trained, yes.

Why did she leave Kirsten's room
in the first place?

Because the killer found her?

Well, there's no sign
of forced entry.

DI Longacre left her door unlocked.

She said she didn't.

Junior officers lie
to their superiors all the time.

In Moscow, maybe.

There was no sign
of a struggle in the room...

Because she ran away.

The struggle happened later.

In the lab, where she was killed.

I'll show you. Come on.

Are you all right?

Fine.

It was just a shock,
seeing something like that.

Mm-hm.

I mean, you never get used to it.

I don't think we're meant to.

Thank you.

I'm sorry, but...

Well, I've come to ask a few
more questions.

What about?

Jia.

I was...

Well, I was hoping you could help me
understand about her research.

Jia worked in phycology.

I'm a geologist.
There's not much overlap.

OK, but... well, I don't know
much about phycology,

and I'm guessing it's got
nothing to do with Freud?

Phycology's a type of microbiology.

Hmm - and that's what Vincent Mair
was, wasn't he? A microbiologist?

OK, so, what,
that's two microbiologists.

One dead, the other missing.

And you met them both
the night before, didn't you?

I met with Vincent to go
through some data,

and Jia came over for, like...

...I don't know, ten seconds.

I don't think we even spoke.

When Vincent went back to Scotland,

he changed his mind
about your report.

Withdrew his endorsement.

I still don't... understand why.

The data on seabed mining is good.

See, my colleague in Scotland
says different.

She followed up on what you told me

about your predecessor -
Siobhan Wilkinson

was forced to resign.

That was for incompetence.

No.

Nah, see, I know it wasn't.

Dr Wilkinson...

...she didn't see the big picture...

...but when you live on Svalbard,
you can't miss it.

This place, it's like...

...having a front-row seat
to climate change.

Every year, it gets worse -
and seabed mining,

however damaging it might be,

was our only chance of stopping it.

So, what, you did what she wouldn't?

You doctored the report.

I omitted some of the outlying data.

I did a little bad
to do a lot of good.

And Vincent found out?

From Jia?

Is that what she discovered?

No. Jia's work didn't have anything
to do with seabed mining.

OK, so, what was she working on?

I don't know. It was something
secret.

She kept her cyanobacteria samples
in a separate cryo freezer,

her research locked in her room.

It was all off the books.

Why?

There were rumours her funding
was from the Chinese military.

Why would the Chinese military
fund a microbiologist?

Could they weaponise her research?

There are thousands of undiscovered
cyanobacteria.

If you can start isolating them,

the applications
are potentially limitless.

Svalbard is one of the best places
to study them,

which is why it's
so hard to get a secondment here.

In fact, one of my students
called me in tears -

they were due to catch the red-eye
but their flight was cancelled

on the day that body was
found in Baltegrad,

and the director closed
the airspace.

The red-eye?
Do you remember what time that was?

5:00, 5:30. Why?

LOCK BEEPS

Does that keep a log
of who comes in and out?

Yes. Thanks.

It has a computer inside
that has all the data.

Do you have access
to that information?

No, I'll go and get Garcia.

Great.

Kirsten,
why are you not in your room?

I need to talk to you.
It's important.

OK.

So, what's this about?

Erm...

How did you know Hodge's body
was in Baltegrad, again?

I told you.

I got a call from
the mayor's office.

You closed the airspace at five.

If the Russians only found
the body after six,

how did you know about it
an hour earlier?

Kirsten, I...I really don't have
time for this.

What aren't you telling me?

It's... It's classified.

Why? What are you protecting?

It's not what, it's... who.

The morning
Hodge's body was found...

...I received this text message.

In Russian, obviously.

It means "British man
dead in Baltegrad."

And this is how you
knew about Hodge?

Yes. Why didn't you tell anyone?

If the Russian authorities knew
that one of their own was leaking

information to me, they would have
found them and killed them.

You should have told me
you got this, Director.

As you should have told me
you brought Polina here.

We both tried to protect someone.

Do you know who sent the text?

I assumed Polina.

She didn't mention anything
when she tried to defect.

And you've called it?

Yes.

It goes straight to voicemail.

VOICEMAIL IN RUSSIAN

Mm.

But how do you know the text
came from Baltegrad?

I...assumed. Ah.

No, we need to trace
where it came from.

Just need you to
look at the computer.

Don't touch anything else, OK?

Yeah.

Yeah.

You were looking for a struggle.

Did forensics find anything?

They dusted for prints,

but could only rule out eight
of the hub's 97 residents.

Could anyone come in through here?

Uh... No.

That only opens from this side,
so...

I mean, they would've needed
a crowbar to get in.

What about here?

No. That's a dead end.

It's the sample store.
Show us, please.

All right, guys.

Oh, I... Sorry,
we keep it at minus 25,

so as to keep the ice core
samples intact.

What do you do with them?

Er... Anything.

If you can name it, ice core samples
can help you study it.

Climatology, zoology, anemology.

I'm pretty sure I made the last
one up, but you get the idea.

Mm-hm!

OK, thank you.

If I want to get cold,
we will go outside. OK.

The last one, please lock
the door behind you.

Wha...

Er, so what time
was that woman found?

16:12.

OK.

OK, so...

Let's see, six minutes before that,
the connection to the door was lost.

Mm. Like I said.

Polina kicked it in.

Except, there's another entry
just before that.

Is that Jia?

Can you print that out?

But go back a week. Sure.

Kirsten did say
she was hiding out in the hub.

Yeah, but we found the evidence
she was gone

by the time Polina got here.

She might have come back.

Or someone else had her pass.

Chen, Jia's colleague,

did take Jia's belongings
after she disappeared.

Let's go talk to him.

If you have the map,

we can triangulate
where the phone was

when the message to you, Director,
was sent, by using the cell towers.

At what time did you receive it?

Er, 4:53am.

Are you ready to receive
the co-ordinates?

Er, yes.

78.47 latitude.

Yeah.

78.40...

Yeah. ..by 15.31...

Yeah.

...and 78.40 by 14.44.

OK.

It won't give you the exact
location,

but where those circles intersect
is where the message was sent from.

And you're sure this is right?

Without a doubt.

But that means...

...the text came from inside the hub.

It wasn't from a Russian
in Baltegrad.

It was somebody using
a Russian phone.

Someone who...

...who must have known Hodge was dead
and where his body was dumped.

His killer.

From the logs,

it looks like Shen Jia was
practically living in that lab.

Svalbard attracts a certain...

...obsessive type.

Now, Chen does not like talking
to police.

I doubt the three of us
will change that.

Hi, Chen.

Can we come in for a chat?

Er, we can talk here.

When Jia disappeared,
you cleared her room, right?

Yeah.

So, you took all her papers
and files?

Mm.

Was her ID in there?

No.

Can we check?

Do you have a warrant?

We can get one.

Then get one.

Shen Jia's research
belongs to the CCP,

and I'm under orders to keep
it secure.

Why? What was she working on?

Ah, Chief. Just the man who...
Ikke na.

What's going on? Kirsten?

Why isn't DI Longacre in her room,
Director?

Because she's under my supervision.

I'm afraid you will have to
wait here, Colonel.

Olsdatter.

So, whoever killed Hodge, text you?

From a Russian number
inside the hub.

Someone's been manipulating
this from the start.

Texting him about Hodge's body,

leaking Jia's extraction
to the Russians...

The only men who knew about Jia's
extraction

were the ones who were involved.
Yeah, exactly.

The British Special Forces.

We'll start with Cunningham.

What's going on?
Stay where you are.

Can this not wait? No. It can't.

Oi, look, if you tell me what you're
looking for, then maybe I can...

What? Lie to me again?

Is this about the woman
that was killed?

If it is, it wasn't any of us.

For a start, I was with her
when it happened.

Pickford was in the cafeteria,
he's got plenty of witnesses,

Anderson wasn't even in the hub.

You can check all this.

Amy.

Look at this.

This is Hodge's bed, right?

Yes, we bunked together.

Did you know about this?

No Russian burner, though.

What are those?

They're, er...
They're tactical maps.

Records of our unit's movements.

Dan shouldn't have kept these.
Could be yours.

No, look at the dates.

I wasn't even on Svalbard then.

These all match Hodge's deployments.

Then maybe he was planning on
sharing them with someone.

The Russians.

We need to speak to Fyodor.

How did Russia know Jia was being
extracted that night?

Well, what... What is this?

Just answer the question, Colonel.

Well, I can't.

Cos I was not told.

Only that the FSB found out
it was happening

and ordered Korotayev to stop it.

It was Hodge that told the FSB,

because he was the Russian spy,
wasn't he?

This is proof that he was keeping
records of his unit's movements,

so that he could share them.

But Hodge was already dead
when Polina defected.

He can't have told Korotayev
she was here.

Someone else must have sent that
text from the Russian phone.

So, who did?

You were the only person
who knew that Polina was here,

and there was no sign of forced
entry into your room,

meaning that she chose
to head to the lab.

Her fingerprints were the only
ones that were on that knife.

She didn't come here to defect,
did she?

Nobody needed to tell Korotayev
she was here.

So, how did he know?

You sent Polina here!

Were you going to tell us?

Polina never wanted asylum.

She just wanted to
get inside the hub.

What was she?

FSB?

Polina Kurkova worked
in administrative...

Enough with the lies, Yakov.

You sent her in here -

but when it went wrong, and she
died, you blamed me to cover it up.

You engineered this whole situation.

You've gone too far this time.

And what about you, Director?

What?

Covering for the British soldiers?

Hmm!

Knowing about Hodge's death
before we told you.

Your predecessor, at least...

Power cut.

NERVOUS CHATTER

They've not moved.

If they do, we need to be ready.

SHE SPEAKS NORWEGIAN

That's not right.

The power should be back by now.

My phone's got no signal. Yeah.

Neither does mine.

Without power,
the cell tower will be down.

Did you do this?
No, Director, this is not us.

Let's just fix it, all right?

I think it's best you leave
until this is fixed.

Nyet.

Evgeni.

What did he say?

What's going on?

Hey.

We're on!

Stay where you are.

Drop it! Drop it!
SHOUTING

Hey! Hey, drop the weapons!

HE SPEAKS RUSSIAN

This was never about finding
Polina's killer.

You just wanted another excuse
to get inside the hub.

Watch them!

ALL SHOUT
Drop the guns! Now!

HE SPEAKS RUSSIAN

Sjef?

This is not a fight you can win.

HE GIVES COMMAND

Anderson, sit-rep.

They're taking the southern
service corridor.

They're headed towards the main lab.

Anderson, meet us at corridor B.

Copy that.

They're inside the building.

I know - they'll be heading
to the lab.

Helvete. If they start firing...

I know.
I'm going to try and stop them.

Everyone needs to
gather in the cafeteria.

Come on!

To the cafeteria,
you know the drill. Get out!

Everyone, yes! Yes! Yes! Yes!

Come on. Come on! Hurry up!

Get down to the cafeteria now, please.

Thank you.
To the cafeteria, come on.

Quickly, this way.

To the cafeteria, come on.
Go, go, go, go...

Evgeni?
HE SPEAKS RUSSIAN

You need to get those men
out of here.

We've had intel on Jia's discovery -

and it's dangerous. Do it now.

Director!

Director, the Russians
are after what Jia discovered.

Fine. Then everyone is safe in here.

She was working with cyanobacteria.

Her research was being funded
by the Chinese military.

What if Jia discovered
some sort of bioweapon?

What if that's what
everyone's been after?

Sir, bad news.

Someone's taken the backup
generator offline.

What will that do to the labs?

Uh, samples will start to defrost,
some will become airborne...

And what if some of them
were dangerous?

No-one should be in the labs
right now.

Right. With me.

THEY SPEAK NORWEGIAN

DCI Silva, don't shoot!

You need to get out of here.

If they're already in there,
then you have to fall back.

Anderson.

Stay with me.

Clear.

Anderson, secure the door.

DOOR BANGS

SHOUTING
Weapons down!

Weapons down!

Stay back, or we will shoot!

Stay back!

Amy!

Unarmed! Police unarmed!

Amy, everyone needs to get
out of there.

How do we contain it? Um...

Evacuate the building.

Decontaminate second.

I need to put on a hazmat suit
and get in there!

Sergei. Dimitri. Stay where you are!

You are outnumbered.

You shoot, you die.

We think Jia discovered
a new type of biological weapon.

The samples could become airborne -

and you're all risking exposure
being in there.

Garcia needs to come in.

Anyone entering will be shot.

We are not leaving without
Jia's discovery.

Then you are not leaving.

Jia wouldn't have left without it, either.

What do you mean by that?

The thing you're looking for
is already gone.

Jia took it.

She would never have left it,
it was too important to her.

How can you be sure?

I have... I have records
of the lab entry log...

Hands! Hands! Hands!
Keep your hands up!

Yeah, yeah. So, let me show you.

Amy, no!

It's the only way to stop this.

Not armed. Not a threat.
Let me show you.

Listen whatever you do,
do not touch any of the samples.

Oh, God...

It's gloves...

Open it.

Slowly.

Empty.

Where is it?
Where is Shen Jia's discovery?

We don't have it.

Of course you do.
That is why you cut the power.

That wasn't us.

No. We thought that was you.

If they're telling the truth,

then whoever cut the power
did it for a reason.

What would usually happen?

Nothing that didn't. Yeah.

Any emergency that isn't a fire,
everyone goes to the cafeteria.

So, someone wanted everyone
out of their rooms.

Oh, my God.

It's too late.

It's done.

We've read you your rights.

Are you certain you don't want
your solicitor on speaker phone?

I'm sure.

OK.

It was you who cut the power,
wasn't it?

I had to.

Because you knew what would happen.

Knew everybody would be
evacuated to the cafeteria.

Including Chen.

It worked even better than
I thought, thanks to the Russians.

After what happened to Polina,
Chen was never leaving that room.

I had to force him out.

Why? Just so that you could
destroy Jia's research?

Is that what you were trying to do
in the lab?

I found Jia's pass
when she first disappeared.

I used it to cover my tracks
when I went inside.

But you didn't destroy
Jia's discovery?

It was already gone
when I got there.

Jia took it on the night
of the extraction.

I just focused on destroying
the rest of her research.

But then Polina broke in.

And you killed her?

I didn't mean to.

What happened?

She screamed at me to give her
the door code for the sample store,

and just attacked.

I tried to run
but she threw me to the ground,

and took out this knife, and...

Well, you know the rest.

I was just trying to protect myself.

But if it was self-defence

then why did you let DI Longacre
take the blame?

A little bad for a lot of good, right?

I was going to come forward...

...but I had to make sure that all
of Jia's research was gone first.

I had to get into Chen's room.

You did all this just to stop
Jia's discovery

getting into the wrong hands?

No, to stop it
getting into anyone's hands.

It's too dangerous.

Is that why you killed Daniel Hodge?

No, I had nothing to do
with that.

I didn't want anyone to die.

That's why I couldn't let anyone
get Jia's research.

No matter what it cost me.

We've arrested and charged someone
with Polina's death.

You mean murder.

She's claiming it was self-defence.

And she has a pretty strong case,
considering Polina was FSB.

When can I interview her?

You'll have to wait.

That is not what we agreed.

But it is what I have decided.

What happened last night,
what nearly happened,

it can never get out.

Not even to our superiors.

Of course not.

HE SPEAKS RUSSIAN

Lorna didn't kill Hodge.

That means I'm going to have to
re-examine his body,

and interview any witnesses
that aren't FSB.

You won't be doing any of this,
DI Longacre.

Your co-operation is required.

We will co-operate with
the investigation.

Just not with her.

Kirsten, I think we should...
That's not up to you.

You are right.

This comes from your government.

What?

Why else would they send another
police officer,

if it was not to replace you?

DOOR CLOSES

It wasn't my decision.

But you went along with it.

I had to. No, you didn't.

After what happened with Polina,

the Russians were never going to
let you stay,

so Sir Ian had to appease them.

But you could've told me.

I was trying to protect you.

By taking my job?
It's not like that.

It's exactly like that.

Is this because you don't think
I'm up to it?

No, of course not!

I just didn't want to see you
get hurt again.

Ah! This isn't about that.

No? Well, why don't you tell me
what is it about?

I shouldn't have to, Amy.

OK.

Look, I've got to update
Sir Ian, so...

...we'll talk about this
when I get home.

I promise.

Just know that I love you.

Even when I'm not very
good at it sometimes.

Director!

Kirsten. Come to say goodbye?

I need to speak to Lorna.

Well, I'm afraid she's being
held at the station.

It's important. Please.

She's lying.

About what happened to Polina,
or...? No, no.

About WHY it happened.

You can have five minutes.

Any longer
and we'll both be in trouble.

Thank you.

Apparently, I'm stuck in here

until three different embassies
can agree what to do with me.

Still, it could be worse.

Not sure how, but...

Polina wasn't looking for what Jia
discovered, was she?

No, she was after something else.

Someone else.

She had your photo in her coat,
and she went to that lab,

because that's where you were.

Because you know where Jia is,
don't you?

DOOR OPENS

We need to talk.

Follow me.

Jia didn't want Russia, China -
anyone -

to be able to recreate
what she found.

Is that why you destroyed
her research?

She asked me to.

She came to me for help,

once she realised
what she'd created.

After what happened to Vincent...

...I felt I owed her.

Where is she hiding?

I'm not going to tell you.

She's in danger, Lorna.

Now her research has gone,

she's the only one who can
recreate her discovery.

Everyone will be trying
to find her -

and they will.

You need to make sure somebody you
trust gets to her first.

So, you told me the Russian phone
that Hodge was using

to contact the FSB has gone
missing, right?

We think someone's taken it.

Yeah. Hodge's killer.

The FSB, they load
all their phones with malware

so they can remotely wipe the data,
in case they're stolen.

But they can use that same malware
to turn the phone back on.

So you can call it?

Yeah. I already have.

PHONE RINGS
The Russian phone.

Henrik?

He must have found out Hodge
was a spy and killed him for it.

Lorna said we'd find Jia
a few miles north.

We're close.

Lead the way.
