A physical altercation with another drinker.

Now, he wasn't charged, so it can't have been that serious, but the reason I mention it is 'cause of the pub it was in-- the Ifield.

Our Ifield?

MURRAY: Hendon Lane.

Now, pretty much everyone who trained at the academy drank at the Ifield.

So I was thinking... What are the chances the ruck he had was with a probationer?

Exactly.

Nice.

(chuckles) He used to play the race card every opportunity, and still does, from what I hear.

SUNNY: When you say "play the race card," what, do you mean, he objects to being called a Paki on a daily basis?

You come from Wales, you get called Taff.

Scotland, Jock-- it's the same difference.

CASSIE: No, it isn't, but let's maybe not go there right now.

So aside from being cocky, what was he like as a person?

Was he good copper material?

Here's the deal-- I always thought Ram would go right to the top or end up in prison.

CASSIE: Prison?

HENDERSON: Listen, the lad was a smart boy.

(chuckling): There's no doubt about that.

He was ambitious, charismatic, very funny-- people liked him.

He was also angry.

Had a massive chip on his shoulder about his color.

You combine that with his risk-taking and his liking power a little too much, well, it makes him dangerous.

But the proof of the pudding, you check his disciplinary record over the years, yeah?

I mean, the guy obviously thought he was untouchable.

And worse still, he had a right to be.

Now, personally, I think if he'd have been white, he'd have been inside by now.

So you think he could have been capable of breaking the law?

And who was that?

HENDERSON: Your fourth name.

CASSIE: Fiona Grayson?

HENDERSON: Yeah, or the Wet Blanket, as we used to call her.

Literally no idea what she was doing there.

I mean, she was a perfectly capable lady, but she clearly hated the whole set-up.

(chuckling) And I wasn't surprised when I heard she quit.

CASSIE: Okay.

Was there any violence in him?

No, the opposite.

No, I really had to push him when we did restraint training.

No, there was nothing violent in Rob.

No, he was a real gentle giant.

And can you think of anything else connected to any of them that sticks in your mind?

Anything you haven't already touched on?

Yeah, the five of them, they formed a little gang.

I was never quite sure what it was.

I mean, they all came from very different backgrounds, had very different personalities, but there was some sort of connection.

Then, on the day of the passing-out parade, I think I saw what it was.

What?

Not one of them had a guest.

Yeah, yeah, exactly right.

(chuckling): I mean, everyone has guests don't they?

Mums, dads, siblings, friends-- someone.

But no.

No, not them.

And I think that's what their connection was.

For whatever reason, they were out on their own.

So you're going to be able to find stuff out, do you think, if it moves forward, keep us ahead of the game?

I'll do what I can.

Whose brother?

Matthew Walsh's.

Turns out he was with Matthew the night he disappeared.

No.

He was having a pee in the bushes when the car pulled up.

Saw everything.

♪ ♪ Yeah.

I remember the case, because of his color.

Whose color?

The probationer involved in the altercation.

So the arrest sheet details that Walsh made a pass at a woman.

Who was also a probie, I think.

And she blanked him, and he got a bit lairy, and then a lad she was having a drink with intervened, and that's when it all kicked off.

After Walsh made racially abusive remarks, I think.

And I'm assuming it was just a bit of handbags, because Walsh only got cautioned.

No, not at all-- Walsh actually gave the lad a bit of a kicking.

So...

So he was let off because my sergeant wanted it buried.

If Walsh had been charged, then there would have been a court case, and the probationer would have got in trouble, and... Obviously, we'd just started recruiting ethnic minorities, so it wouldn't have played out well for anyone.

So the fact there's no other names in this report, apart from Walsh's, that was deliberate.

I didn't write this report, my sergeant did, and he's been dead ten years, but yeah.

I'm guessing he was protecting the witnesses, the girl, and very particularly the Asian lad.

♪ ♪ CLIVE: And as we were walking across Napley Green, I decided to duck into a bush for a pee.

Just as I did, I heard this shout.

"Oi!

Walshy Boy!"

I turned, and I saw this car about 50 yards away, with a bloke getting out of the front passenger seat, and he was just running at Matty.

And do you remember what he looked like?

Asian guy.

And what did your brother do?

Well, the bloke looked pretty useful, and angry.

And there was others in the car, so he just ran.

And I had just a second or two to decide.

You know, show him that there was two of us, eh?

Except I'd never had to fight in my life.

So I ducked down.

And I hid.

And then the driver got out, tall fella, ran off in the direction of the others.

And then about 30 seconds later, a third man.

And I could still see two others in the back seats.

After about five minutes, they got out, as well, and they all quickly off in the direction the others had gone.

But these two were women.

And that was it.

I never saw them, or my brother, again.

Why did you never say anything about this at the time?

I had a job, in Cyprus, in a club, and I had to fly out the next day to start.

This was before mobile phones, so I didn't even hear that he was missing for weeks.

And then when I did get back, early June, pretty much everyone just reckoned he was lying low, because of the warrants that was out for him.

Everyone reckoned he'd just turn up one day.

(humorless chuckle) Except me.

Because in my gut, I think I knew that he'd died that night.

(breath shudders) And the reason I never said anything, that's because I did not want anyone to know what a sniveling, gutless coward I was.

Thank you.

(tosses papers on table) Okay.

So we now know for sure that they all got out.

And in pursuit of the victim.

Exactly.

Which means, as far as I'm concerned, they're definitely all in the frame now.

JAKE: So here is an allotment.

And if we draw a line up from where the car stopped, up here, up here, and ending somewhere in the allotment, it fits very well with the various witness statements' sightings of the chase.

And if we can identify where exactly on the allotment this plant might have grown, we might find his actual place of death.

Mm.

I mean, my guess is... Look, it would have to have been near the road, to pull the car up to.

Maybe we can even get some boards up.

Might trigger some old memories.

Yeah.

Absolutely.

Okay, very good, thank you.

Kaz.

The only concrete thing I have is on Fiona Grayson.

A 1993 dangerous driving conviction.

Trying to get the original files.

Okay.

But nothing on Elizabeth Baildon.

And nothing on-- well, apart from his internal disciplinary record-- on Ramjeet Sidhu.

Which we're looking into.

Yeah, and Dean Barton, no criminal record.

Although I am having trouble finding a couple of basic documents.

Can't find his birth certificate and I, and I can't find him on the census pre-'91.

Okay.

And something else just to feed in as background, all five of them had no guests at their passing-out parade.

No family, no friends, no nothing.

Yeah, that's one to mull on, maybe.

And definitely a picture is starting to emerge of Ram Sidhu being a person who pushed the envelope, even back then.

We know he was probably first out the car.

So was probably the most likely to catch up with Matthew first, and then this afternoon, Murray slightly struck gold.

So, three weeks before Matthew disappeared, we got pretty good evidence to suggest that, in a pub in Hendon, he committed an ABH on Ram Sidhu.

(chuckling): No... CASSIE: The fight was over a girl.

No names in the arrest sheet, but we know our suspects were a bit of a gang, so there's a fair chance that they were all drinking together that night, and the girl was even Fiona Grayson or Liz Baildon.

For various reasons, Walsh only got a caution, and Murray's trying to track down Suzie Montgomery, the landlady.

But I think alongside opportunity, fairly reasonable now to suggest we also have a possible motive.

Albeit one that, for whatever reason, seems to have escalated from a reciprocal slap to something far more violent and involving four other people.

So I think we pull Sidhu in now, confront him with this, and see what we get.

Thank you, guys.

But an awful person who-- well, at, at least I hope, despite what I have just told you-- you still love.

Well, of course.

So surely, surely, that means you can tell me stuff.

About your past.

About your family, whoever they are.

Things that, that maybe you think will make, make me hate you or fear you or whatever, I don't know, because it just won't.

But what is killing me is the secrets.

The years of secrets, the writing of a Mothers' Day card to a mother you told me that died.

And going to Calais when we were supposed to have given up all that crap years ago.

I mean, you weren't lying about where you were today?

Just, I, I can't take it anymore, I just...

I can't take the secrets and lies, not when we've got so much else to deal with.

So, please, just talk to me, Dean.

You're tired, Marne.

I am, too.

No, Dean.

We will do this, but not now.

Please.

Dean...

Please.

MAN: He's just down there at the end with the white beard.

JAKE: Okay, cheers, mate.

♪ ♪ KAREN: So those are the original files connected to Fiona Grayson's driving conviction in '93.

And it turns out that a child died during this incident, in the car that she collided with.

Wow.

One of the officers attending smelt alcohol on Fiona's breath and so obviously tried to give her a test at the time.

But she was so upset, crying hysterically, that they were unable to successfully give her one at the scene, so she was arrested and taken to the local nick where a blood test was taken there instead.

And?

It was lost.

CASSIE: Lost?

Lost where, the lab or the nick?

The nick, before it got sent to the lab.

Which nick was this?

Kingston.

Are you heading where I think you're heading?

KAREN: So, I checked where both Ram Sidhu and Liz Baildon worked at the time.

And?

Baildon worked at Kingston nick from '91 to '94.

Oh, man.

Yep, and in the '91 census, it details Liz and Fiona as living at the same address in Thames Ditton, about a mile or so from Kingston town center.

But at the time of this offense, they're living at separate addresses, but both are still in the same area.

SUNNY: And if that blood test had come back positive, Fiona Grayson would be in jail.

(inhales sharply): Definitely.

Okay, so there are three explanations here.

One, this was just a coincidence.

Two, they were an item and she contrived to have the blood sample lost for personal reasons.

And then three.

They weren't an item, but Liz Baildon was blackmailed, Fiona Grayson using whatever happened with Matthew Walsh as some kind of leverage.

I know what my money's on.

Mm.

(cellphone ringing) (ringing stops) Leanne.

Hey, Cass, any chance you could pop in for five minutes when you have a chance?

(rain pouring) RAM: What can I say?

Just now.

We found out, just now.

It's actually happened.

(sigh trembles) I feel differently.

(crying): Jesus, Ram.

I know.

I'm sorry, but...

I've just spent the last seven days slightly killing myself mentally to get to where you were.

(voice breaking): Trying somehow to find a way of thinking that maybe we didn't have to do this thing.

This brutal, really horrible thing.

You just changed your mind.

No, I...

I just, um... (exhales) What if something happened to me?

What if I got ill, or I...

I don't know, anything, that meant you had to do it all on your own?

You know, I just started to think how, how difficult that would be for you.

I mean, I'm not definitely saying we do go for a termination; I'm not saying that yet.

I'm just saying, can we keep thinking?

For a bit longer?

♪ ♪ (softly): Okay.

CASSIE: Okay, am I seeing what I think I'm seeing?

LEANNE: So, I'm seeing a sharp-ended object approximately ten centimeters long, maybe three-quarters of a centimeter wide, inside the skull cavity.

And what do we think that is?

No idea.

I need to open the skull up now.

It got in pre- or post-mortem?

Again, I, I don't know until I open it up.

But best guess?

From its position, you'd logically assume it entered through the temporal bone fracture, which, when I examined it properly, actually contained remnants of brick dust.

So two theories.

Firstly, he was being chased, and at some point, he tripped and fell, hitting his head on a wall which maybe had a metal spike of some sort-- an old bolt from some railings or whatever-- and this is what killed him, breaking off inside the skull.

Or he tripped and fell, hitting his head, which rendered him unconscious, and whilst unconscious, he was basically stabbed through the head wound with this object.

Jesus.

(whispers): Yeah.

So, first theory, a chase that went tragically but accidentally wrong.

Second theory...

This was no accident.

This was a very violent and very deliberate murder.

Correct.
