I had to call the police.

CASSIE (voiceover): So, obviously, we can't confirm anything until we get a DNA match, but we have good reason to believe that the remains are those of Nicholas Howard Whitmore.

Last seen on December the 30th, 1978, at a Clash concert at the Lyceum in the West End.

At the time of his disappearance, he lived in, in Hammersmith and he was training to be a nurse.

Now, he disappeared about two-and-a-half years after Jimmy, but, crucially, at least two years after the Slaters moved into their house.

Can we assume that the body went in the ground close to the time of death?

We'll assume nothing yet.

Any obvious connections to Arlingham House or to Jimmy?

No, not yet.

But we've made preliminary contact with Nick's family, and I'll be able to speak to them properly later today.

Okay, Murray, the original investigation determined that the, the bank card was last used in a pub in Hampstead.

It was called the, the King George.

And that was on the 31st of December 1978, so in an ideal world, we'd need to place Eric Slater in or around that area on that same evening.

It's, it's a tough one, I know.

Got it.

Okay, Jake, where are you with Mackie?

Seeing him at 6:00.

And is there anything else coming through from the house?

No, no-- nothing more.

From the house, the gardens, or the copse.

Okay, that's good.

CASSIE: That's it for now.

Thank you, everyone.

Guv, surely we've got the wife saying she saw him put the body in the ground.

Actually, it's becoming clear that she has no idea what she saw.

And no jury would ever convict him on her testimony alone.

So... we need more.

The woman...

The girl, Joanna, that I had a relationship with.

(sighs) She got pregnant, and she said that it was by me.

So, obviously, I offered to pay for the termination.

And I thought she'd done what, what she wanted.

Two years later, she rang me and told me that actually she hadn't been able to go through with it.

(sighs) And she'd had the baby.

I was shocked.

And scared.

But I said I would support them, the baby.

And I did so until the child, Thea, was 18.

Thea's now 38, and she's made her way in life.

As her father, I've tried to help out as best I could.

Sometimes with emotional support.

Sometimes with money.

Not fortunes.

A hundred...

Occasionally a thousand.

But always with, with money I didn't have.

So I stole it.

Of course.

And seeing if you can help me out with something that's been troubling me.

Well, if I can help, I will.

Okay, so, I, I now think that the assault on Paul West was actually nothing to do with football, but was, as his sister said, a homophobic attack.

I... Well, I must confess, I couldn't see a link between West's attack and Jimmy's murder.

I mean, Jimmy was... clearly in a long-term heterosexual relationship with Joanna Bridges.

Yes, JoJo.

Exactly.

Hm.

But what I didn't know, until earlier today, when a colleague of mine spoke to an old friend of Jimmy's from the hostel, was that when Jimmy first came to London, he was homeless and broke with no obvious way of making money.

That he did what a lot of young runaways did back then, which was to work as a male prostitute.

Now, in the months before he was killed, we know that Jimmy borrowed 50 pounds from a gang to pay for an abortion for JoJo, and that that money was then stolen.

So he, he desperately needed money.

Another 50 for the abortion and the original 50 to pay back to the gang.

Mm.

Now, he, he tried to sell a car, but like you said, everybody knew it was stolen.

Mm.

So, in his desperation to find the money, we think he went back to selling sex.

How awful.

And you found out about that.

No.

And because I think you had a violent hatred of homosexuals, at some point in July 1976, you murdered him and buried his body in the cellar of Arlingham House.

Absolutely not.

I had absolutely no idea about any of what you've just told me.

Well, that's interesting.

Because Jimmy's friend says not only did you pretty much know everything the residents were up to, but that you told him you'd seen Jimmy servicing a male client down an alley behind a Hampstead queer pub.

What friend?

A resident of Arlingham House called Alan Mackay.

Known as Mackie.

Oh.

(clearing throat): Never, never heard of him.

And listen, half that lot were drug addicts.

The, the rest were alcoholics.

Do you really trust what any of them have to say?

Well, these are the same people you say you invited to your house, Eric.

I don't think I've ever even been to Hampstead.

I had no idea Jimmy was doing what you were saying.

And what the hell this has to do with this other lad... Well, let me tell you.

Because today I've been talking with Nick Whitmore's sister and father.

And that was his name, by the way.

Here's the thing, Eric.

It turns out that Nick was gay.

That Nick often frequented gay bars and pubs and, in particular, a pub called the King George.

In Hampstead.

Like I just said, don't think I've ever been there.

Do you know when the cash dispenser was invented?

No.

1967.

First one ever used in the whole world was in Enfield, by Reg Varney.

Do you remember him-- "On the Buses"?

Vaguely.

So, by 1978, there were hundreds, all around the country.

And there was one at 364 Haverstock Hill, Hampstead.

About 20 yards from the King George.

You're one for keeping records, aren't you, Eric?

(papers rustling) Must be the... the bookkeeper in you, I suppose.

This is a copy of a document.

We found this in your, in your house earlier.

Can you tell me the date of this statement?

December 1978.

CASSIE: And, and look at the entry dated the 31st of December.

What does it detail?

ERIC: A cashpoint withdrawal.

Ten pounds.

And that number by the entry corresponds to a specific machine.

Do you know which one it is?

Well, we rang the bank and we asked them.

It's for a cashpoint on Haverstock Hill.

Number 364.

Right next to the pub.

So we can now place you within 20 yards of the last known whereabouts of Nicholas Whitmore.

So we now have a connection between his murder and Jimmy's.

On top of the numerous connections to you and Jimmy.

If you start asking for other stuff, this dialogue ends, the process continues to trial, and... Trust me.

On the evidence we have, you will be convicted.

(papers rustling) So it is time to talk.

Do you wanna...?

(beeps) CASSIE: Resuming interview with Eric Slater.

Present: DCI Stuart, D.I.

Khan, Duty Solicitor Elise Hughes.

Time is... it's 10:17.

(pen clicks) (softly): It was Claire.

I'm sorry, can you say that again?

Because I didn't hear you.

I said it was Claire, my wife.

It was Claire.

ERIC: I met Claire at Hunter and Regis in, in 1969.

They, they made air conditioning units.

I worked in accounts and she was, she was in the typing pool.

I, I've never been very good with the ladies.

But I always felt very relaxed around her.

We found the same things funny.

Always had plenty to talk about, and one day, she just asked me out.

A bit unconventional, but I didn't mind.

Our first date was at the Locarno in Queen's Park.

We kissed outside and I bought us saveloy and chips from a takeaway in Townmead Road.

Yeah, we courted for a year or so and then got married before we moved to Dollis Hill, where I got the job at Arlingham House, which was-- which was round the corner.

1971, that was.

Yes, she, she wanted... kids, immediately.

Because, you know, we were neither of us spring chickens.

Which, I did, too, very much.

But there was a problem.

Which I think she always knew about in her heart and... hoped would change.

And I wanted it to change.

I wanted it to change, but it wouldn't.

I couldn't.

What problem?

I liked men.

I didn't want to.

I absolutely didn't want to.

Just how I was.

You liked men and women, or just...?

I loved my wife.

I mean, I still do.

Very much.

And obviously, I was able to... you know, we had two boys.

But right from when I was a kid, I just had this thing inside of me that made me... Want to be with men.

Men like Paul West?

I never wanted to hurt West.

He asked me to... rough him up a bit.

Some men seem to like that.

CASSIE: And Jimmy?

And Nicholas?

Well, Jimmy, he just wanted money.

Nicholas, I, I met in the pub.

And how did they die?

I, I would never have hurt Jimmy.

I loved him.

I'd never have hurt him.

(crying): I'm sorry.

I'm so sorry.

(sobbing) ELISE: I think we... might need five minutes.

Five minutes-- no more, please.

We're taking a short break in the interview.

Time is-- it's 10:41.

Would you...?

(clicks) (cell door buzzing) You gotta hand it to the man.

He is smart.

And if you're gonna blame somebody else, then choose a woman whose memory is completely shot and can't even deny it.

His face, though.

What?

It was the same as in his house when we asked him about Paul West.

And last night at the station when we said they were gonna charge him.

When he said it wasn't him.

And now I know why I felt so bad afterwards.

Why?

Because I believed him.

You call the station.

We need to re-arrest Claire Slater.

♪ ♪ KAREN (voiceover): Yeah, but, I, I thought the CPS said that we could...

SUNNY (on phone): Yeah, yeah, DFI.

Which one of the sons took her?

Um...

Uh, I'm not sure.

I'll, I'll call their homes.

Okay.

(hangs up phone) (quietly): Bollocks.

OFFICER: Mr. Wilton?

Yes.

Your wife was pulled out of the river.

A passerby jumped in.

She was unconscious when she came out and was taken immediately to St. Thomas's.

I'm afraid that's all I know.

(softly): Murray?

Have we got mobile numbers for the sons?

Don't know, maybe.

Why, are neither of them at the house?

No.

I'm not sure they will be for a few days.

I thought we were done with her, and I, I kind of told them they might want to lie low for a week or so.

(phones ringing) (clicks, beeps) ERIC: I, I'd stayed late to, to see him-- Jimmy.

Again.

And she must've just guessed.

I think she always knew when I was... Well, this, this one time, she, she came to find me.

And what you need to know is that she wasn't well mentally.

We'd just had Leslie, and ever since she'd been... Oh, well...

Very... very sick.

And, of course, in those days, the doctors, they, they just told you to pull yourself together.

You know, so, she never, never got any... any help.

And I never...

I never saw her coming down.

It was dark.

Well, she, she saw us.

She, she hit him with... with a hammer she'd found on a workbench.

Just once.

But I, I knew from the sound it made that... Ooh, and then she was screaming at me, calling me all the names under the sun.

I was trying to get my hand over her mouth to keep her quiet and by the time I'd sorted her out, Jimmy, well...

I, I think he was dead before he hit the floor.

So...

I locked the cellar, took Claire home, came back later.

Of course, I, I couldn't risk carrying him outside, so...

I buried him there later that night.

Will you tell his mother, please, that I said prayers... (sobbing) I said prayers for him.

I, I looked after him.

And of course, I, I assumed that, you know, we'd be caught.

He'd be found.

But he never was.

And, oh, that night.

I vowed to stop all of that for good.

And we moved up to Ely.

Yeah, to get away from London.

It worked.

Yes, it worked.

Yeah, two, two years later, we had little Matty, and it was all... You know, but it was the '70s.

There was no work, and...

I ended up having to get a job back in London, two days a week in Camden.

And I started to... stay out late again.

So one night, she left the kids with a friend, came down to London, followed me... (clears throat) From work up to Hampstead and found me with Nicholas in my car.

Of course, she went for him.

Pulled him out, punching...

Kicking and then he was on the ground...

Blood everywhere.

She, she always said that it was him who'd drawn it.

The, the knife.

But she was... Ill.

Very ill again after, after Matty.

So, I...

I pulled him back, back into the car.

(sighs) I, I want you to know that I stood outside police stations dozens of times.

Dozens of times after Jimmy.

And... What did she feel?

Well, when she got better, of course, she was devastated by what she'd done.

But, you know, we had a little boy.

I mean, if we'd both gone to prison... And after Nicholas Whitmore?

I, I drove my car into a tree two weeks after Nicholas.

I wanted to die.

But actually, in the end, I think...

This, this... was a fairer punishment.

I'm sure Jimmy and Nicholas's families... wouldn't agree.

Hello?

THEA (on phone): Hi, Ellie, you don't know me.

My name's Thea.

I'm your half-sister.

(traffic humming) ELISE (voiceover): And how bad is it?

I spoke to her GP earlier.

I mean, obviously we'd have to get our own assessment done, but, yeah it's, it's fairly advanced.

She first presented four years ago, but the decline in the last few months has been particularly rapid, apparently.

ELISE: Right.

Well, you know what I'm going to say.

Could she properly remember what she's been accused of?

Could she tell her solicitor her side of things?

Could she challenge what witnesses say in court?

And, if she can't do any of those things, she's unfit to plead.

Okay, so... Well, there are a number of questions here.

I mean, if he's worked all this out, why would he not say it was her?

Assisting an offender carries a maximum sentence of ten years.

Now, given his age he might get, I don't know, eight, out in four.

For double murder, he's gonna die in prison.

Yeah.

What's your gut feeling?

That all of it is true.

To admit what he did, my feeling is that, that was actually harder for him than saying he killed them.

Which might sound unbelievable, until you think that for the first 30 years of his life, what he was, what he did was illegal, and utterly disgusting to 99% of the population.

I think that shame absolutely remains.

Then why did he admit it, then?

Because in the end, he knew that his boys were gonna lose their, their mother pretty soon, anyway.

I mean, already had to a degree.

So telling us what he did, I think his reasoning was that that meant at least they didn't lose both.

And is there any evidence to corroborate his version?

I think we'll find evidence that he had multiple homosexual relationships.

We might find medical records confirming she had some form of post-partum psychosis.

Maybe even we'll be able to place her at the hostel on the, on the night Jimmy died.

And then if we do, then his narrative is better than ours.

(knock at door, door opens) We've got a mobile number for Matthew Slater's work.

No answer from him yet, but his work have told us where he is.

Local police are on their way.

And what happens to her?

Well, she'd just get a supervision order.
