Kate going to social services

has nothing to do with her childhood,

or Caitlin's wellbeing.

It's about Carl.

A couple of weeks ago,

he came round to fix one of our windows.

We had pizza, Caitlin helped out.

It weirdly felt like being a family again.

Well, he was supposed to be home by eight.

Turns out, it was more like ten,

and he said the next day he'd got it in the neck.

Apparently, Kate was livid. Screaming at him.

And how was Kate with you?

Fine. Her usually friendly self.

Though she was just biding her time.

Cos she filmed that footage of me and Caitlin two days later.

And you don't think that was a coincidence?

No.

I think it was revenge.

Kate is pathologically jealous,

possessive, if you will, when it comes to Carl.

She just can't help herself.

Any threat to the relationship is a threat to her.

The only difference between Anna and now

is she's learnt to conceal it. To plan for it, to bide her time.

Exhibit A - Find the Gemma campaign.

She's left nothing to chance this time.

Which is why we can't find Gemma's body.

And why Anna's still potentially the weak spot.

...finding out about your affair?

If Kate knew about you and Gemma, maybe she did something about it?

No. Detective...

...Kate is a passionate, emotional person, OK?

But she's not violent.

I hear you, Carl.

But I also appreciate that she's your wife

and the mother of your child, so what I'm suggesting...

What you're suggesting is crazy, and I'm being polite now.

It's completely crazy, OK?

DCI Conroy joining the interview.

I wanna go back to your first wife for a moment.

In the weeks before Anna disappeared,

a woman was harassing her.

Could that woman have been Kate, and not the barmaid you were seeing?

No.

So, just to be clear, based on Anna's description,

there's no way it was Kate bothering her.

OK, just to be clear, Kate never came to Westport.

Plus our relationship, fling,

ended months before Anna disappeared.

Is that how Kate saw it?

- What? - A fling?

Oh, my God!

- OK... - Are you really gonna tell us

that Janice's presence in Westport

on the day that Anna disappeared, vanished,

has nothing to do with Kate?

Our working theory is that she was down there

cleaning up Kate's mess.

And making Anna disappear.

What Gemma and Anna had in common is very clear.

They were a threat - obstacles to be removed,

so Kate could have you all to herself.

I made a promise once.

Twas the night before we left for England,

when Anna's parents invited us over.

Her dad, he said he couldn't blame us for going, but...

...he made me and Pavel promise to always take care of Anna.

I did. I did promise.

Whatever the precise details of their deaths,

the common factor here is Kate.

Yeah, I want to talk to my lawyer.

Interview suspended, 14:16.

We need firm evidence against Kate.

Which Carl is in a unique position to get.

He's the only person that she can't hide from.

How does any of this help us?

It doesn't, unless we exploit his position.

We need to put a wire on him.

And use him to get a confession from Kate.

No way. Forget it.

Just from a legal and safeguarding standpoint.

OK, ma'am...

Legally, it's unorthodox, but it's not unprecedented.

And as for the risk, Carl has a cool head,

a world-class poker face, and on top of that, he's motivated.

What else have we got?

I'm DC Martin Young.

I work in Surveillance, and I have a proposition for you.

We need your help.

It will involve you wearing a recording device

and returning to your family home.

We need to know what happened to Anna and Gemma.

And frankly, you're in the best position

to help Kate tell her side of the story.

To get the truth out of her.

Of betraying her?

If she's innocent, you can prove us wrong.

I don't recommend you co-operate with this.

I've done a boiler-plate risk assessment,

but it needs some love.

The ACC's a details man, so bury him in minutiae,

or we'll never get it past him.

I called Jim Owens at Firearms.

So, this is "dangerous, but not that dangerous".

So, no snipers.

But he's gonna make sure there's a couple of ARVs patrolling nearby.

I want everything in the street kept as normal as possible, OK?

No interruptions.

You OK with all that, Stella?

Be happier if certain interested parties

were detained elsewhere, boss.

Greg?

And Janice. To name but two.

Everything all right between you two?

- Fine, boss. - Good.

CID can yank Greg on a dozen different pretexts,

and Janice must figure in some cold case files?

What about Carl?

What about him?

What's the contingency plan?

If he gets cold feet?

The first thing I wanna say is thank you.

We understand the magnitude of what we're asking.

So, we'll be able to hear you via an earpiece,

and you'll be able to hear us.

I want you to, loosely, follow this script,

which has been tailor-made to elicit a confession.

Try not to change the subject.

And try not to ask questions that are too specific or loaded.

And if you do ask questions...

...try not to make them consecutive.

Stay away from the windows, but if you...

Huh. It's Kate.

OK, let's just treat this as a rehearsal, OK?

A what? What do I say?

The police made a mistake, they've let you go,

you'll see her at home. Short and sweet.

Hi, babe.

Where are you? Are you OK?

Hey, everything's fine.

Stupid police made a mistake, now they've released me.

What... What happened?

We'll talk about it at home, OK? I've got to go now.

OK, I-I-I'm just dropping Chloe at the pool,

so, I'll see you at home...

- I love you. - Love you too, babe.

Good.

- OK, say something for me. - Hello?

OK, great.

When you get home, I want you to open your back door,

put your front door on the latch,

and open a ground floor window about two inches.

Something we learned from the more experienced house-breakers.

It's good to have multiple points of exit

- in case anything goes wrong. - "Goes wrong"?

It's just a precaution.

You OK?

My friend, this is Kate we're talking about. Just look at me...

- Yeah. - Hey. Hey!

The love of my life,

- the mother of my daughter. - I understand that...

- OK? - Yes.

- OK. - Uh-uh.

Kurwa... Tell me, how am I supposed to...

Kurwa!

I can't do it. No.

Carl, I understand your feelings.

I understand your feelings, I don't blame you.

- But this is a way we can find out... - Martin...

- ...what happened to Anna. - ..Martin...

- You, know, it's not... - Hey, hey, hey, hey...

It's no.

Bring him in.

I want you to keep your promise.

Yeah, that's great. Uniform has Janice.

Copy, team in place.

Should be ship-shape in the next 10-15, over.

Kate's still at the pool.

We'll give you a heads-up when she's leaving.

Roly's gonna be the welcome party at CID.

You guys all right down there?

Keep Greg occupied till we're done and dusted, over.

All set.

The ARV's incoming,

but they know to keep their distance.

OK, feed's up and they're back.

Here.

Oh, cheers.

Can I have a word - now.

Sure.

Vic, you'll let me know if anything happens?

Yeah, I will do.

What is this about?

She has to go - now.

- Why? - Don't make me spell this out.

To you, or to anyone else.

I see.

Don't put me in this position, mate.

Sort it out.
