Episode 2

ALAN CUMMING: This is "Masterpiece Mystery!"

CASSIE: David Walker died of a single stab wound to the chest We're looking for his killer.

CUMMING: Previously on "Unforgotten"... We didn't row about it, the row didn't get out of hand, and I didn't accidentally kill him.

MARION: Listen I've gotta go, but I'll see you on the ward.

MARION (on phone): Bye love.

TONY (voiceover): Who was that?

Zoe, the girl with Non-Hodgkins.

She got your personal number?

SUNNY: Do you think there's a chance that he was your client when you worked as a prostitute?

If we tell Janet, we could lose Flo.

LINGLEY: He said he'd been abused by a teacher.

CUMMING: "Unforgotten," tonight, on "Masterpiece Mystery!"

Which obviously rules out any of the people we're currently talking to.

SUNNY: Unless the murder was committed on behalf of the abuser.

What, the primary school teacher ordered a hit?

Walker allegedly confronted him 25 years later.

The teacher could have been anything by then.

With everything to lose if David had gone to the police.

Okay, well, look, let's keep an open mind about that.

Okay, so Colin Osborne, now, he worked at Klein Egerton in the late '80s, but then leaves very suddenly, it's only about a month or so before David died.

Now, it's probably a complete coincidence but can you speak to them please?

Yeah.

And then Sara Alazi.

So, she says that she was living in Rome between March and December 1990.

Can you speak to the Border Agency, see if-- how-- we can confirm that?

Yeah.

Well, I think... yeah, that's it.

You let him go to the police.

And then you just deny it.

You're a lawyer.

He's a drug addict who's just had his stepdaughter taken away from him.

Why on earth would the police believe a word he says?

And what if there were CCTV in the supermarket car park?

Or another witness?

We could easily check the CC... No.

Sorry.

But...

This is the simplest way.

Why?

I just think we're none of us in the right frame of mind.

Why would I not be able to relax?

Well, because of what's happening at your work... Work's fine; why would I not be able to relax?

Do you know what he said to her, before we arrived?

About wanting to hurt someone?

Listen, Jason is angry and confused... And I get that, of course I do, and you also have to get how that might spook a 15-year-old.

Well, yeah, maybe, until her dad very quickly reassured her that Jason is simply trying to process an incredibly traumatic event, and that, actually, he is the gentlest, kindest man in the world.

Which you obviously did, yeah?

Sure.

Yeah, good.

And are you okay?

I'm as fine as a woman who's just learned her late husband was murdered is ever gonna be.

Paul, you don't seem to be really understanding that.

Well...

I have to admit you are beginning to ever-so-slightly scare me.

Scare you?

And I'm wondering if there's anything you need to tell me.

No.

Hi.

Hi.

I'm DCI Cassie Stuart.

I'm leading the investigation into your father's death.

Can I just say how sorry I am for your loss?

Um, thank you.

Would-would you like to go and find somewhere a bit more private?

No, I just...

I...

I just wanted to know when I could visit him.

Right.

Are you really sure that's a good idea?

He's my dad.

No, I understand...

Better surely to remember him how he was.

Except I don't, hardly.

Remember him how he was.

I mean my mum made me a memory box after he went.

Lots of stuff of his in it.

And there's a jumper in it that I used to smell, to remind me of him.

Except it's gone now.

The smell.

Used it all up I guess.

(stammering): And I actually need to see him.

I just wanna be with him.

I want to say goodbye.

Will you leave this with me?

Have you got a number I can call you back on?

Yeah, um, use the mobile.

Right, I'll come back to you as soon as I can.

Thank you, DCI Stuart.

Cassie, please.

And, really, there's no need for thanks.

I'll see you.

Um... ♪ ♪ SUNNY: What year would that have been, Mr. Gregory?

From when he was about seven, till when the teacher left, about a year later.

So that would be what, 1958, '59?

Roughly.

Did Mr. Walker give you the teacher's name?

No.

Or if he did tell me, I don't remember it.

Sorry to ask this, but... Did he ever give you any specific details about the abuse?

It was bad.

Proper... rape and stuff.

Did he ever report it, I mean, is there be any record of it?

As far as I know, he told no one.

I mean, kids just didn't then, did they?

Just kept it all in.

Now, you said to a colleague of mine that you often thought it was why he lived his life the way he did.

What did you mean by that?

The women, the drink and drugs.

To blot it all out, all that... shame and guilt.

So he had drug issues?

Yeah, you could say that.

And did he have relationships outside his marriage?

Yes, he... he did have affairs, but mainly I was talking about prostitutes.

Right.

In fact, that's kind of why we stopped seeing each other.

I wasn't remotely interested in that sort of thing and we just kind of drifted apart.

And this was when?

Mid-'80s, I guess?

But then in about '87, he rang me, out of the blue, and we hooked up again.

We went out for a beer a few times.

Which was when he told me about Firdown, the school where it all happened.

Do you happen to know if he ever told his wife about the things that happened to him there?

He told me he'd never been able to.

For whatever reason, the only people he ever spoke to about it were me and, when he tracked him down, the teacher himself.

So you know for a fact that he actually spoke to him?

He found out where he lived, went to his house.

And what did the teacher say?

Denied it all, of course.

Then got abusive, then threatened him.

♪ ♪ CASSIE: This was him about a year before he died.

No, I don't recognize him, I'm afraid.

Sorry.

So can you think of any reason, um, why this address might've been written on a travel card found in his office desk?

Absolutely no idea.

When did you say he died?

We think some time about early May 1990.

Well, maybe the person that wrote this, just wrote down the wrong address.

Well, that's certainly a very real possibility.

So, can I just check if anyone else was living here in 1990?

Oh, it would've been just me and my husband.

He's passed away now.

Hang on-- when was that time Daddy and I were in America, and Marion broke in?

♪ ♪ Mum was winding me up, and I knew it would annoy the ass off her to tell her that you meant more to me than her.

So I did.

Which is very sweet of you, Zoe, and you mean an awful lot to me too, but all I'm saying, all anyone is saying, is we just need to keep that relationship professional, and within the boundaries of the hospital.

Soz.

(siren blaring in distance) (phone ringing) I owe you an apology.

TONY (on phone): What for?

It was Zoe who told her parents about the phone conversation.

Oh, right, not a problem.

Uh, listen, that's not why I'm calling.

A police officer's just been round here.

Sorry?

TONY (on phone): Yeah, she'd already been round to your mum's, and then Elise gave her our address.

What did she want?

She said she was investigating an historic crime and that she wanted to ask you a couple of questions.

TONY (on phone): She didn't tell me anything more than that, so I rang Elise.

She said she'd been trying to get hold of you, but your mobile went straight to voicemail...

I was on the ward.

TONY (on phone): But Elise said she'd told her that it was about a murder, dating back to 1990.

They've only just found the body apparently.

♪ ♪ CASSIE (voiceover): So her married name is Kelsey, but she was single in 1990, so, can you run a check under her maiden name, which is that Marion Dunphy?

Right, okay.

And how did it go with James Gregory?

Interesting.

According to him, David definitely did use prostitutes, and on a fairly industrial level.

Jesus.

Do you know, I just... met his son this morning?

What a nightmare this is going to be for him.

It's going to get worse.

Walker was into some really weird stuff.

Like?

Violent kind of weird.

Tying up, S and M stuff.

And did Gregory think his wife knew about it?

No, he thinks not.

So the other possibility is that he went too far with Sara Mahmoud, and she attacked him back, and then he died as she tried to defend herself somehow?

Okay, okay can we just be very careful how we share this information for now.

Yeah, of course.

And obviously we'll need to speak to Sara Mahmoud again and Tessa Nixon.

Yeah, I'll set up both.

Oh, and what about Firdown, David's school?

I spoke to the current head.

And?

She-she was suitably appalled, I mean without a name, she wasn't sure how she could help us.

This is abuse that is alleged to have occurred about ten years before pretty much the oldest current teacher, was even born.

Right.

I mean even identifying a possible suspect is going to be as good as impossible.

On top of that, there's a really good chance that whoever David Walker was talking about is already dead.

Right, okay.

I'll see you later.

I'd come straight from Cambridge, Colin from Kingston.

They recruited from a Poly?

Oh, they took Colin.

Because?

He got the highest marks in the aptitude test anyone had ever scored.

And then he went on to do well here?

If he'd stayed, he'd have ended up running the place.

Did you get any sense of why he did leave so suddenly?

No, I mean, I worked with him and I liked him, but I didn't really know him well.

He was quite a reserved man.

One day he was here, the next he was just gone?

Have you spoken to Colin about this?

Hello.

DCI Cassie Stuart.

Have you got five minutes for a quick chat?

Oh, yes.

Yeah, sure.

No, sorry.

Who is he?

His name was David Walker.

He ran a small chain of clubs in the '80s.

Never been a clubber myself.

No, me neither.

Music's always too loud for me.

Mmm.

Well, obviously, as you know, we've spoken to your mum and sister.

And she seemed to think that you might have been living in her house at some point in early 1990?

Did she say I broke in?

Well, she did, yes, actually.

My father was on a lecture tour of America for three months and I was temporarily homeless, so, I had a key, let myself in, stayed there for a few days.

If that's breaking in... Sure.

Well, as you say, it-it couldn't have been her that gave that address out, because she was abroad, so could it have been you?

Sure.

Oh, okay, um... but you don't have any recollection of doing so?

From some time in 1990?

No, sorry.

Okay, no problem.

So your mum said you left home in about 1985?

Yup.

And you stayed in London?

Yeah.

Whereabouts?

Various places.

And was 32 Smoke Lane one of them?

I was there for a while, yeah.

This was the address, in fact, that you gave after you were arrested in 1988 for assaulting a police officer...

I never assaulted anyone.

...at a demonstration in North London.

A policeman attacked me, I was defending myself.

For which you were found guilty at Horseferry Road Magistrate's court and fined 100 pounds.

You look like a smart woman to me.

I'm sure you couldn't be so spectacularly dim as to suggest that a police officer from the '80s-- well from any point in the last 50 years actually, couldn't have lied?

I'm not sure why you're being so defensive, Marion.

I'm being defensive because I was on a perfectly legal march, exercising my right to protest, and I was assaulted by a police officer.

And you're now trying to imply that I have some kind of violent past, and that therefore I must be connected in some way to this unfortunate man's tragic death.

And I find that annoying, I'm sorry.

Are we done, because I have a very busy ward.

Sure.

Great, nice to meet you.

And you, and if we need to speak to you again..... (door opens, closes) ...we'll be in touch.

LINGLEY: So there are no records that can confirm whether Sara Mahmoud-Alazi was or wasn't in the U.K. We're checking with all the main airlines for flights to Rome in March 1990, but I've been told not to hold my breath.

Okay, keep pushing them.

we do need to be able to confirm where she was at the time of David Walker's death.

Absolutely.

I've left her a message to call us back.

Okay.

Jake, where are we with the photos?

I went through to Tessa Nixon's.

Unfortunately she said she chucked out most of the ones of her husband about 15 years ago.

Why?

Trying to lay ghosts to rest, she said.

Or bury them.

JAKE: And I'm still waiting to hear back from the Tory offices about their photo archive.

Okay-- Murray?

I spoke to a senior guy at Klein Egerton today and there's definitely something odd about Colin Osborne's departure, I don't know what it is yet, but my guess is that they're going to close ranks.

I'm on it.

Right, good stuff.

Okay, following my rather prickly chat with Marion Kelsey earlier, we ran a tenancy check on the, uh, Smoke Lane address and we found, yes, one rather interesting result.

So this is Sinead Mary Quinn.

She lived at Smoke Lane from 1988 to 1991.

And then in 1992, Ms. Quinn was in prison for ten years, for her role in suspected IRA activities.

(all murmuring) SUNNY: So we then went back to Marion Kelsey's arrest sheet, and discovered that the march she was on, was actually a protest march campaigning for the release of the Guilford Four.

So we have one IRA activist, we have the murder of a Tory Party fundraiser.

And linking them both... ...we have Marion Kelsey.

♪ ♪ So as of today, we are now splitting the investigation into two strands.

The first will follow our existing line of inquiry, that one of our persons of interest murdered David Walker because of some connection around the time of his death.

Sara Mahmoud's as a prostitute.

We're looking at a possible I.R.A.

motive with Marion Kelsey.

And his wife remains of interest, that's for obvious reasons.

And then Colin Osborne, the only person so far that we've conclusively proved actually met David Walker.

Murray, I want you to focus all your attention now on finding the Klein Egerton temp, Maria Gonzalez.

And Fran, we really need to speak to Sinead Quinn.

And any news yet on Colin and Sara's alibis for May the 8th?

Still waiting on both, I'm afraid.

Okay, we keep on that.

And then we move into... very different territory.

We already know that David Walker had a lot of secrets, and now it seems we've just found another.

So myself, Jake, and DI Khan are starting a second line of inquiry, to investigate if David Walker was murdered not because he was going to expose what happened to him 30 years before his death, and not because of any of these reasons, but maybe as retribution for sexual abuse he committed himself.

Now, two of these, at least-- Colin Osborne and Sara Mahmoud-- have dysfunction in their lives very consistent with a childhood trauma.

Now, all of them seem to have had some sort of connection with David Walker in the months before he died.

I think we have to consider the possibility that one and... maybe all of them, were victims of David Walker as children, and then years later took their revenge.

So I want to interrogate every single aspect of David Walker's adult life, from when he left school to when he died.

But most importantly, they were also regularly attended by children from local care homes, local borstals, and from the streets.

Now, these vulnerable kids were plied with drink and often drugs, and then on a number of occasions, sexually assaulted.
