I made a mistake, Dad.

I slept with Rick.

Hiya, love. Sorry, I was just about to call you.

Don't you "love" me. Why didn't you answer your phone all night?!

You're saying that Robbie followed and strangled Mari Quinlan?

And hid her body in the bunker.

He's denying that he killed both nurses.

He's just taking the piss. Yeah, well, he was pretty persuasive.

No trace of Mel's DNA on the scarf.

Why did you tell us it was Harvey at the wheel?

Did someone put pressure on you to say that?

Time's up, Rick.

Who told you to say that it was Harvey? It was Rick!

You made your friend lie in his wife's murder trial!

Both of you conspired to pervert the course of justice!

Why don't I pack off the kids to Mum's tonight,

cook us a nice meal,

take your mind off all this crap at work?

You're one of the best, Rick,

but I have no choice but to suspend you from duty until further notice.

What are you afraid of, love?

DOORBELL

All right!

Have you lost your keys again?

Can I help you?

Argh! Argh!

That someone else is going to die.

I told Vaughan what I did...

..so I've been suspended. What?

Wait.

I didn't mean for you to do that.

You're a brilliant detective, Rick.

Now she tells me. But you messed up.

Big time. Story of my life, eh?

I didn't...

..sleep with you to distract you or...

..keep tabs on you.

I loved you.

Still do.

Me, too.

That's the problem.

Well, I'm home now, so, erm, I've got to go.

Helen?

Shit!

Helen?

Helen!

MOBILE PHONE RINGS

Gail, have you spoken to Helen since she dropped the kids off to you,

or heard from her at all?

I don't want to worry you, but just let me know if she gets in touch.

So, now that you've caught the killer,

do you think you might stay?

Do you want me to? Well, it would be nice for you to see the kids,

rather than sending them vouchers.

Don't worry about your dad.

We've got Jamie now. We can manage.

Not that she exactly helped out.

I love having you home, Ffion, but I wouldn't want to hold you back.

Hey, Pembroke Dock's none too shabby.

Well, there's still work to do.

Loose ends and all that.

Why is Rick here?

Oh, don't tell me he's one of your loose ends.

Her phone was in the kitchen,

her car was...was outside.

She was in the middle of cooking us supper. You've tried her parents?

She dropped the kids off at 5:30pm and that's it. Her mates? Of course!

Did you ring her?

Did you tell her about us?

No. She is a nurse!

And tomorrow's the seventh day. And what if you're right,

what if Mel didn't kill Abbi?

And what if she's just been taken? You need to get a grip.

We will find her.

God, how many times have we said that to people?

OK, OK. So, come on, where do you want to start? The bunker?

You've been suspended, remember?

Call it in, go home, check Helen's phone

and I'm going to keep you updated, OK?

You can't keep thinking like that, Rick.

She might come back.

No. Sorry, Rick. Search teams are starting at first light.

Rick. I know... I know I shouldn't be here.

I'm so very sorry.

Do we know anything about this John Shaw, who he is yet?

Yeah, the prison has supplied the address for the visiting order,

but it was derelict, so he must have provided a fake ID.

OK, well, we know that Mel isn't the killer.

We know that now because the real killer is with my wife.

Rick, sit down.

I have to ask you,

both of you,

does Helen have any reason to want to teach you a lesson?

Could she be hiding out somewhere?

Erm, no, no... Why would she?

Was there any tension because of you two working together?

Look, I know that Helen

wasn't happy to start with, but... She was angry that we'd spent

the night away in a hotel and that I didn't keep in touch with her.

She asked me if anything had happened between us

and I said no, I reassured her, but...

She was fine, she was in the middle of cooking us supper.

I don't... I don't understand. Where is she?!

KNOCK ON DOOR

Just heard from the prison. They're running checks on the CCTV

MOBILE PHONE RINGS

Right, good to go!

Hello, love. Mam, is Jamie there?

No, he's late, and he's not answering his phone.

OK, listen to me, lock the doors. If Jamie comes, don't let him in.

Why not? There are police officers on the way to keep you safe,

but Jamie's dangerous. What? He's a sweetheart.

How exactly did you find him?

Well, I Googled dementia carers, I found the Castledge Agency...

Castledge Agency. What's his surname?

Tilston. Right, I'm off.

No, no, Griff, don't leave the house.

Do you know where Jamie lives? Hi. I'm ringing about one of your

dementia carers - Jamie Tilston. With his mum and dad,

in town somewhere. But he's from North Wales.

That's not a crime, is it?

Well... Do you have Jamie's number?

Erm...

Mam, look, this is serious!

We think Jamie might have been involved in Abbi Rayner's murder.

OK. Thank you.

It's a different number to the pay as you go he used to text Harvey.

No, it's switched off.

I'll get in touch with tech, see what they can do.

OK, thanks. Thanks.

He's been a carer for five years.

Castledge, where he's been working

for the last four months, say he's one of their best.

It's not a coincidence that he's ended up at my parents' place.

Mogsy, go to his address, take Uniform, see what you can find.

I'll get his car reg and then run an ANPR search.

16 hours. What?

Between Sian Hinton going missing and her time of death. 16 hours.

The pathologist said that he kept her alive in the bunker

for a few hours before he strangled her.

Helen went missing around seven o'clock last night.

If Jamie is following Harvey's pattern,

that gives us until midday, at best, before Helen is killed,

so there's still time.

Abbi Rayner's murder wasn't the exact same MO.

No, but that was Jamie's first attempt.

This time, he might get it right.

Rick, you shouldn't really be on police premises.

Why not?

Because DS Sheldon is the missing person's husband

and can't be involved in any way.

We'll do everything we can to find Helen.

Rick, before you go, have you got a photo of Helen?

It was right under your nose.

How didn't you know?

Police officers! Police! Police!

Clear.

Clear.

RATTLING

Helen?

Helen?

Hi.

Hi. Have you seen your mother? No. Why?

Gran dropped me off while she went to the shops, so I could pack.

Is everything OK, Dad?

Why am I staying with Gran and Gramps? Erm...

..well, you know, your mother and father are really busy at work,

and we didn't want to put pressure on you to go back to school.

But you thought Mum was here.

Yeah, that's why I was so surprised. HE CHUCKLES

It stinks of bleach here, too.

Er, there's a picture. I'll send it to you now.

MESSAGE ALERT

Could be his mum. God knows.

But there's an address on the back in Llandudno.

He only moved down here recently.

Shall I run some checks in Llandudno?

It's where he is now that matters and whether or not he's got Helen.

There is a tablet here,

but it's locked. We haven't got the time to send it off.

We need to access that information now. Hang on,

I've got his date of birth in front of me.

Mogsy, try 170795 as his passcode.

No luck. Harvey's date of birth?

180358.

No.

What about the date of the first Heart Knot murder? 181111.

We're in. Now look for the last-seen location

and that should show you where the phone was last switched on.

The road to the west of Cleddau Woods, 20 minutes ago.

We've got a location for where Jamie's mobile was last turned on.

It's on the road west of Cleddau Woods. Shit! When?

25 minutes ago. I'm heading over there now.

Rick, he had photos of Abbi and Helen. He was following them.

MOBILE PHONE BEEPS Look, I've got to go. Sit tight.

Sir? The texts we found between Harvey and Jamie

were only the tip of the iceberg.

We've found a lot more messages in Jamie's phone records,

which Harvey must have deleted. What do they say?

We're looking specifically at the lead-up to Abbi's murder.

One week before, Harvey texts this,

"There's no such thing as morality, Jamie. We're all capable of evil,

"but some lack the courage to act on their true desires.

"I know you have it in you to kill.

"This is your time to shine, my boy."

Sounds like Jamie was being groomed.

You know, maybe Rick was right.

Maybe all of this will follow the exact same pattern

as the MO with Sian Hinton. Which gives us 90 minutes, at best.

I want to know where every single bunker is in this fucking woods!

She was going to clock off after the next patient, about 3:30pm,

so she could go food shopping.

Still not heard anything? No.

Listen, you haven't seen this guy hanging about, have you?

Can you not see how busy we are? He's been stalking her.

No.

No. Can you check who her last patient was,

then, please? Come on, Jan.

If it helps.

Anna Jennings.

Nothing in here, boss!

It's 11:45am. We're running out of time.

Are you sure there aren't any other bunkers? No, it's all I've got.

Just the three World War II bunkers that are on the list.

KNOCK ON DOOR

Dad, I need your help.

Another nurse is missing.

Yeah, it took me a while to put my scarf back on. I'm sorry about that.

Have you come about the assault? No.

Er, I'm sorry, Mrs Jennings... Call me Anna.

How can I help?

Erm, you were the last person to see my wife in the hospital.

She's a nurse, erm, and she's missing.

You didn't happen to see this man,

did you, hanging about?

No. Sorry.

Who is he?

Oh, you look exhausted. Why don't you come in?

We've found three World War II bunkers,

but I'm sure that you said that there was another one.

Do you remember that case that you worked on when I was a baby?

Erm... Er...

Oh, erm... Dewi Osborne! Swansea Crown Court.

I acted as his defence.

He'd trapped his wife and kids in a bunker, in the woods,

and...and held them down there for...three weeks.

Where was it, Dad? Because it's not on our list.

You're asking something now, Ffion.

Erm, it was a Cold War bunker.

Poor man was terrified that there was going to be a nuclear attack.

The court decided he was unfit to plead,

but I thought his...his fears were well-founded.

Oh, there's really no need.

Please.

I rarely have visitors.

Thank you.

Oh...

She was kind, your wife. Er...

Helen.

Insisted on waiting for the taxi to arrive,

even though she was in a rush.

"Date night with my hubs," she said. "An excuse to glam up."

Right, erm...

The, erm... The bunker was built

in 1982.

Do you have the location, Dad?

I've got the exact coordinates here.

51.5113 degrees north.

Yeah.

4.5522 degrees west

Dad, did you tell Jamie about this bunker?

WHISPERS: Who's Jamie?

Never mind. Mam, thanks.

And, Dad...

..you're my hero.

How are you, by the way?

Dying.

Those biscuits might well outlast me.

Brain metastasis from lung cancer.

It's why I came forward.

Sorry if I messed things up for you. Oh, no, I...

I did that all by myself.

Erm, would you, erm...

Would you mind if I use your bathroom before I leave?

Ffion, I just wondered if...

..if there was any news. I mean, it's... It's nearly midday.

I mean, fuck, why wasn't I with her? KNOCK ON DOOR

Background on Jamie Tilston.

Might be worth a glance before we start.

Interview with Jamie Tilston. DI Lloyd, DS Howells present.

Where's Helen Sheldon, Jamie?

The nurse who's missing.

I read all your text exchanges with Paul Harvey.

I can see that you were in awe of him.

Star-struck, even.

Is that why you strangled Abbi Rayner?

Is that why you abducted Helen Sheldon?

Paul Harvey is very persuasive,

even more so in person, and you met up with him, didn't you? On the...

Er...

..October 17th.

How was it to meet your hero in person, Jamie?

You wouldn't be the first young person to become obsessed with

a charismatic serial killer.

It's grooming, really...

..and, in your defence, you were manipulated.

I wasn't. But it's not too late to help yourself, Jamie,

so tell me, where have you hidden Helen Sheldon?

It won't work, Ffion. I won't tell you where she is.

I also know that you cared for your mum, Mandy...

..since you were a boy.

Till she died of a fentanyl overdose four months ago.

Leave Mam out of this, please. You moved here shortly after that

and then you wrote to Paul Harvey.

Now, deep down, I think you're a good man, Jamie, who, in the depths

of grief, got reality and fantasy mixed up and just became

another one of Paul Harvey's victims. I approached him.

I wrote to him. And did he ask for your help?

Did he ask you to copy his killings, so he could launch an appeal?

I'm not his victim. I chose to kill the nurses.

Are you saying that Helen Sheldon is dead, Jamie?

Yeah.

Where's her body?

Help us understand.

Why visit Harvey now, when your mum had just died?

Were you looking for a father figure?

No, Ffion.

Paul Harvey is my dad.

I didn't know Paul Harvey had biological children.

Run Jamie Tilston's DNA through the system

and see if there's a match with Paul Harvey.

Mam's from here, they had a fling,

and by the time she found out she was pregnant,

he'd already met Anna, and so he gave Mam money to move away.

So he chose Anna over your mum?

That can't have been easy for her.

Yeah, like how Rick chose Helen over you.

Sucks, doesn't it?

Mam didn't want me to contact him

but, years ago, before he went to prison, I came back and saw him.

He told me never to contact him again because his bitch wife, Anna,

could only have stillborn babies and wasn't right in the head.

She made him choose his foster son over me.

A boy the same age, living my life.

When did you visit them, Jamie?

When I was 16.

12 years ago.

So, around about the time of the Heart Knot Murders?

Just before.

And so, when your mum died, you contacted your dad again?

I could reach him in prison and I wanted to say sorry.

For what?

For killing the nurses back then, too,

and letting him take the rap.

I thought you'd blame the foster kid.

I heard him and Dad argue.

I used to spy on them like I did with you, Ffion.

And you put Dad away.

So why not come forward, Jamie, and confess,

if you wanted to do the right thing by your dad?

How is it that a 16-year-old boy abducts, drugs and strangles

two nurses and dumps their bodies,

without us even knowing that he existed?!

I mean, I'm impressed.

I'm waiting!

Talk me through it!

Can I have a solicitor now?

Interview suspended at 12:40.

I did do it, Ffion.

I killed them all.

DCI VAUGHAN: The DNA is a match.

He's Paul Harvey's son.

The duty solicitor can be here in two hours.

MOBILE PHONE RINGS

Hey, Mogsy.

I don't know what he's playing at, but I don't believe he committed

the historical murders.

Trying to get his dad off the hook?

Maybe he killed Abbi and Helen to convince us we'd got the wrong man.

But if he's making false confessions about the past,

how can we believe him now?! He was in the bunker, Ffion.

Yeah, OK. Thanks.

They found Jamie's car parked in the woods.

There was nothing inside.

Then we keep searching, even if we're now looking for a body.

Do you want me to update Rick?

No. I'll do it.

Better start with your wife, then.

The best thing for you to do is just to let us go.

I'll explain how you're still in your husband's thrall, even now.

He abused you. He never laid a finger on me.

That was a story we made up.

He hit Mel. Robbie?

That was for his own good. To make him a proper man.

I always thought Robbie was a war hero.

He never wrote to me, he never visited.

Then he turned up here a drunk loser.

So, what, you decided to frame him for Abbi's murder?

That whingeing bastard Jamie was meant to do it, but he bottled it.

I told him to get Robbie's DNA on the scarf,

but he messed that up, too, so when there were doubts about

Robbie being the murderer,

we decided to frame Jamie instead. SHE LAUGHS

I mean, he wanted to be part of the family.

I was about to take your wife to the bunker

for Jamie to have his first kill, when you turned up here.

But Paul killed the nurses, right? Nurses let my babies die...

..then kept me on a ward

by an empty cot,

while all the other mothers nursed their newborns.

Demons!

Do you think I'd have let Mari Quinlan take my boy away?

I took her for a cup of tea...

..drugged her...

..while I confided in her about the abuse,

and then I strangled her.

We hid her body in the bunker, till it was quiet in the woods.

What about Sian Hinton? She was asking questions

in the hospital, so...Paul abducted her for me.

We kept her alive longer to find out who else knew.

You killed her? And dumped her body.

You were all over Paul, so it seemed like the right plan.

And then he was picked out in an ID parade...

..and he offered to take the rap.

That's true love, that is, Rick. Something you know nothing about.

Jamie told me...

..you slept with Ffion

when you were visiting my husband.

How could you do that to the mother of your children?!

No, please... Wait!

HELEN GROANS

Wait!

What do you expect to gain from all this?! Revenge.

You stopped me from reuniting with my husband.

It's my last chance. I'm dying.

No!

Right... Please...

Please don't kill her. Kill me. She didn't do anything wrong.

I was the one that put Harvey away! Please!

Any last words, Rick? Please, Anna, I beg you...!

Police officers! Help!

Argh!

OK... Helen!

Helen?

She's not breathing.

Ffion! Aargh...!

When Jamie couldn't strangle Abbi Rayner...

..Anna Harvey, who was keeping watch, stepped in.

She hid the body, carved a heart knot in a tree

and Jamie planted the scarf in Mel's den.

That couple spared no-one, in their bid to re-unite.

So far, Jamie's been arrested and bailed for aiding and abetting

and perverting the course of justice.

I suppose he was nothing more than a scapegoat, really.

If I hadn't pushed Alex to lie...

If we'd have known that Anna Harvey was driving the van...
