The more nuclear power stations we have in this country,

the more dangerous our lives are.

We have other ways of making power and energy.

Let's move towards these and away from nuclear power forever.

Let me finish by quoting last year's Department of Environment white paper.

It asserts one positive trait of radioactivity

that facilitates waste management is that with time comes decay.

This is nonsense!

It is the process of decay that causes the raft of life-threatening dangers

that have brought us here tonight.

Bottom line? We're not muppets. Let's not be treated like muppets.

Thank you, Jackie.

Now, we've got time for some questions.

- That's good 'cause I've got a couple. - Toby!

I'm bored of TV dinners and bored of my right hand.

But you must be bored of whining losers turning personal failure

into righteous fury about causes they really care nothing about!

I mean, come on! You must be missing the store cards, at least.

- Ignore him. - Oh, that's right!

Listen to the Zen master.

Does he get any more excited when he's nailing you?

You know, back at uni, she wore a mink stole to our college ball.

In fact, I've got a picture of her wearing it and nothing else.

Do you want to see it? Yeah, come on!

Let's see what the Zen master's made of, shall we?

- Yeah? You want to fight? - Call the police!

- He's breaking his restraining order! - You're still my wife, you slut!

I don't know what was worse, Toby or the look Penny was giving me.

Yeah, they've really got a lot in common, our two exes, don't they?

Hey, you were really good tonight, you know.

- No, I wasn't. - No, no, you were.

They were really listening.

It was great. It was passionate, you were so informed...

I love you.

That's weird. The lights.

There's somebody in the house.

Hello, police. MAN: Yeah.

You need to send someone to Cherry Tree Farm.

Cherry Tree Farm? MAN: Yeah.

What's your name, caller? MAN: It's near Dunwell, Norfolk.

And your name?

Tom, we're off-site.

Yeah, we are off-site. Go wait in the car.

- Sir? - Yeah, yeah, yeah, yeah, good.

So tell me, why are we giving this woman Penny Coulter an interview?

She called last week claiming to have information that casts doubts

on Toby Holmes's conviction for the Cherry Tree Farm murders.

- Oh, right, yeah. - It seems like...

Yeah. Penny Coulter's estranged husband, Marcus, here,

and his girlfriend, Jackie Holmes, who was married to...

- I gave you that file half an hour ago. - To Toby Holmes. I'm catching up.

I'm catching up, all right?

Spencer was one of the first officers on the scene.

Yeah, along with his partner, Tom McQueen.

Mmm. When he was a PC in the Atomic Energy Constabulary.

Right. So what's happened to Toby Holmes and what's his current status?

Judge handed him a life means life in '89.

- So he's out now, is he? - No, he's on the never-never list.

Last year he was moved to Birch Hill High Security Hospital

for biting a guard's cheek off.

- So why is he on the never-never list? - It says in the file.

No, it doesn't.

- So what's the new evidence? - She wouldn't say.

You could have insisted, couldn't you?

Well, she could have put the phone down and never called back.

These things aren't allowed in there.

One of the key pieces of evidence against Toby Holmes

was a blood-stained sweatshirt found in his incinerator.

But Toby insisted it wasn't his and that it had just been put there

by whoever did the killing, you know, the murderer.

Yes, the first part's true.

For all I know, the second part may be, too.

- This is my husband. - With Jackie Holmes.

That's the burnt sweatshirt.

Ah. So you're telling me that this isn't Toby's sweatshirt,

that it, in fact, belongs to your husband.

In '88, you were asked if you recognised this sweatshirt.

And I said I'd never seen it before.

My husband didn't invite me on his little weekend break with Jackie.

But how come you just got this photo now?

We're talking about how many years ago here?

- Eighteen years. - Eighteen years,

and you walk in with this now.

Last week, I gave my nephew Marcus's old 35mm camera.

I found the film inside.

So until last week you had no doubt in your mind

that Toby had killed your husband and Jackie Holmes?

- No, none. - None. Absolutely no doubt at all.

We were all there when he called her a slut.

You're still my wife, you slut!

That's what the killer wrote on the wall.

- Well, anyone can write... - What do you think now?

I don't know.

- Will you reopen the case? - Why would you want us to do that?

- I don't understand. - Well, let me explain.

This doesn't mean that Toby Holmes is innocent.

But it might be enough to initiate a retrial and get him released,

but it doesn't make him innocent.

Now, do you want to go through all that, are you sure?

Or do you just want to forget about this,

take this photograph and walk straight out the door?

I just want the truth to come out, whatever it is.

Do you not hear that a lot in the cold case unit?

All the time.

That's why I ask.

I can get some background from Spence.

No, he doesn't need to know about this now.

- Why not? - Because if it goes anywhere,

he can't be involved, and if it doesn't, there's no point bothering

with something that disturbed him so much in the first place.

- Okay. - Check with the chemist

- where she had that film processed. - Will do.

- Morning, Felix. - Morning.

I want you to order up some evidence. Cherry Tree Farm, 1988.

- Okay. - 1988.

- '88. - '88.

- Thank you. - Okay, sure.

- Spence. Nice of you to join in. - I was in court.

- Who was that? - Who was?

The woman who just walked out, 50-odd.

Oh, she's a witness from that building society robbery I'm working.

It got sent through automatically, part of a batch on the DNA retest list.

- And they tried SGM? - Yeah, in '96.

SGM Plus in 2000. Couldn't get a profile.

- With a low copy number, you might. - Yeah, well done. Yeah.

The 34 cycles yields 16 billion copies of the source DNA.

Plus the mere 250 million with SGM Plus.

- Oh, Boyd. - I know.

So, what is this possible DNA?

It's a partial blood print found on the light fixture

where the female victim was strung up.

No, she was wired up, in fact, wasn't she?

Mmm.

What is this?

Lipstick.

This is the wire.

Oh, my God.

I don't like it when a forensic scientist says, "Oh, my God."

Oh, my God.

So, he lifts her up and binds her hands to the light fixture.

But could one person have done that?

Yeah. It says here he used a stepladder.

If she was alive, she might have been cooperating.

- Cooperate in her own death? - Yeah, well, it's all about hope.

You know, a victim will go along with anything if there's hope around.

- And where's the hope in that scenario? - He hadn't killed her yet,

so she didn't know she was about to get her face cut off.

From the path report, there's hope that she never did.

Hey, you're not in a white coat.

Her neck was broken before her face was cut.

Two neck breaks does seem mighty vicious.

Yeah, well, this man, Holmes, he was an officer in the Marines.

That's what they do, you know. Break necks for a living, kill people.

Her wedding ring was lodged in her gullet.

So that's where the husband as prime suspect comes from.

Mind if I check the manual log-in for today, please?

Sure. SPENCER: Cheers.

Hey.

Yeah, the judge let me off early for good behaviour.

Yeah, I'm good to go.

How about six?

Okay. Laters.

- So, where's the real thing? - Look on the back.

- Central Lab. - Central Lab.

Central Lab, yes...

Central Lab...

- I used to work there. - Of course, you did!

- Mmm. - Right!

Which gives me access to the most power-hungry thermocycler in the land.

- But you can see these marks here. - Yeah, just there.

Why couldn't they get the DNA from them?

Protein decay, caused by the heat from the light socket.

Ah, and you're saying this couldn't be Jackie Holmes's blood because...

Well, it could be, but it was about 13 centimetres above her bound hands.

- Uh-huh. - Plus they also found a shred of latex

from a surgical glove.

Spencer was involved in the original investigation

but he doesn't need to know about any of this.

Right, you don't want him distracted, then?

From what?

- Well, he's in court, isn't he? - Oh, yeah, yeah. Yeah, he is.

- And it's his birthday tomorrow. - Oh, is it?

- Yeah. - Oh.

What are you doing? It's my round.

- Is it? Sorry, I lost track. - Bollocks, you lost track.

Oi, oi, oi, oi, oi. Your money's no good around here, all right?

- Come on, Spence, don't insult me. - I'm not insulting you.

Look, I'm earning, you're not, okay?

Cheers, mate.

Plus you always make the effort to come up to London, so there.

Now, that is true.

I'm still having none of this Spence-benevolent-fund shit.

- All right? - All right.

Seriously, Tom. If you ever think about coming back up to London...

Couldn't afford it, mate.

Come on, I'll give you half board and get you some security work, sorted.

- Well, it's a sweet offer, but... - No, there's no buts, okay?

- Where's the "but"? - Cornwall suits me.

Surfing, straightforward lasses, and nothing to remind me of the job.

- Happy birthday, mate. - Cheers.

Hey, I get it. He's a black cop, I'm a black cop.

Yeah, well it was either that or a steam train.

Nice. STELLA: Blame me.

Come on. No, I got it. Stella, shh. I got it. It's personal.

A personal touch, that's nice. I really like that.

- Have you been celebrating all night? - What?

- The whiff! - I don't stink, do I?

Sorry, I'm just... Have you got a minute?

Yeah.

I had a shower. I don't really stink, do I?

Yeah, you do. STELLA: No.

It's not impossible that you put the lid on back to front, though, is it?

No, no, it's not impossible, but the evidence has been packed

nearly but not quite the way I left it last night.

- Uh-huh. - And also there's this.

Okay. Now, keep an eye on the box. I'm just zooming in.

You see the label? It's gone.

So we can see it's been moved but we can't see by whom.

Yeah. And the default recording setting is set at 10 seconds per minute.

There's a bunch of other ratios,

the most infrequent being 30 seconds every half hour.

Now, our intruder changed the setting

and then changed it back again before they left,

which tells us two things.

- They're very smart... - And they got into the system.

Yeah, exactly.

Which is no big surprise. The same access card gets you into both.

Right.

Yeah. Now, the computer stores every access.

Mmm-hmm.

Now, I checked the log of the footage.

There's a free half hour when the box was moved.

Check the name.

- Spence. - Mmm.

Look at the time. Three in the morning.

But nothing was taken.

Maybe he didn't find what he was looking for.

What, the blood trace that was going to Central Lab?

Well, it's possible.

I didn't even think Spence knew we were investigating the case.

He didn't.

He didn't.

You heard the news about Central Lab?

There are things I can't go into,

but I can confirm that there was a suspected arson attempt

at 4:45 this morning and much of the laboratory was destroyed.

Tragically, WPC Kelly Chambers, who was on duty at the time,

lost her life in the fire.

And our thoughts go out to her husband Mark and her young son.

Commissioner Sullivan, Charles Winton, Times.

How much evidence has been destroyed?

That's definitely something I can’t go into. Next.

Miranda Harrison. How many court cases will be affected?

Honest answer? No idea. It's much too early to say.

Commissioner, you've got Commander Drake

of the anti-terrorist operations here.

Does that mean that you suspect terrorists are involved?

Um, no, it doesn't.

As yet, there's nothing to connect this incident with Al-Qaeda

or any other terrorist organisation.

However, the sophistication of the attack and certain evidence

which we found at the lab means that we can't...

Turn it off, please, someone.

I've just spoken to Central Lab.

The blood trace from Cherry Tree Farm was destroyed in the fire.

Have they got a DNA profile?

They were due to submit it this morning to the database for a match.

Oh, shit. Shit.

Well, this can't be a coincidence.

I know you've known Spence for a long time.

It's not a question of loyalty.

If it's not a question of loyalty, then we have to share this

with Central Lab fire investigation.

Just give me a second, will you? Just...

So, Spencer. I need a list of his incoming, outgoing calls

- for the past two weeks. - Okay, with your approval, yes.

- Personal emails. - I need access to his computer.

And I'm going to hold his mobile phone.

Now, if this doesn't turn anything up...

- Go to your superiors at the FSO. - At the FSO, yes.

Yeah, I don't blame you.

I can't, I don't believe Spencer's got anything to do with this.

Maybe his pass was stolen, his access card.

Have you asked him?

- No. - Well, why not?

Because once I show my hand, Grace, I'm committed,

- and then there's no way back from... - Show your hand!

- This is Spence we're talking about. - Mm, mm, mm.

Why didn't you just tell him about the investigation from the off?

Because he was busy. I didn't want to distract him.

If it came to nothing, it would have been a waste of time,

- wouldn't it? - Oh, come on, Boyd!

What are you worrying about? You think he's involved in it?

Are you suspicious of him?

He was a kid in '88, all right? And this case damaged him, you know?

It scarred him. He told me many times.

That's the word he used, he was scarred by it, all right?

Now, when you're in that state of mind, you're crazy,

you do crazy things, you know? You make mistakes, you cover up,

you protect people.

Okay. Yes, okay, I agree, but that was 20 years ago.

- Well... - What are you saying?

That you think Spence is now capable of burning down Central Lab

and killing a policewoman?

The evidence that was destroyed was from Cherry Tree Farm.

He was involved

in Cherry Tree Farm.

I've arranged for you to meet Toby Holmes.

- Have you finished looking at the file? - Yes.

- At Birch Hill Hospital, 11:00 today. - Okay.

I want to know what you make of him,

whether you think he's the kind of man capable of slicing his wife's face off

or having the presence of mind to wear surgical gloves to do it.

Well, from the cases of facial injuries that I've studied, he might be.

- How come? - Well, it's like love gone sour.

You know how prostitutes traditionally

will do anything and everything but kissing?

Really? No, I didn't know that.

- Oh, didn't you, I... - No.

Thought you might have read about it somewhere.

I might have read about it, yeah. Yes, I suppose.

- Well, it's about the face. - Uh-huh.

It's sacred. It's what we are, it's what defines us.

It might not be our most private place, but it's out most personal.

So the motivation to destroy it is typically personal.

Yes. It takes a special will. I mean, serial killers will rarely go there.

Are there precedents?

Yes, there are. In the late '70s, the wife of an East End gangster,

one Mel Isaacs, gave birth to a mixed-race child.

Mm-hm?

She suffered the same fate as Jackie Holmes with one exception.

- She was alive when he did it. - Oh, God.

And she didn't die.

The neighbours alerted the police and they got there in time.

- We lost an officer at the scene. - Okay.

- Okay. Grace. - Yeah.

Holmes's passport from prison to Birch Hill

was biting a guard's cheek off, by the way.

Great.

What's up?

I found a probable virus on my PC

and as we're on a network, I thought I'd just...

What kind of a virus?

Similar to the W32 Hybris.

And it's bad?

It infects DLL files, so all email messages are...

- Replaced with scrap codes. - Yeah.

Did you tell IT about this?

Yeah, but they were busy, they couldn't find anyone till later

so I thought I'd step in.

I'll check mine, save you the trouble.

Spence?

Spence!

Yeah?

- Hi. - Hi.

One of the jurors dropped dead. Forty-one, heart attack.

All right. Come on in, I want to have a word.

- Take a seat. - Sure.

From now on, it's herbal tea and salad for me.

What's this about?

I'm reopening Cherry Tree Farm.

You had no idea I was going to say that.

No.

There's possible DNA which could confirm Toby Holmes's guilt or not.

Great. When's the test?

Just run it by me why you were there, when as an AEC officer,

your remit was Dunwell Nuclear Power Station.

Sure. AEC had jurisdiction 20 miles around Dunwell,

and Cherry Tree Farm was well within that.

I still don't see why you were called to a domestic crime.

Because local law enforcement was a 20-year-old PC

whose wife was having a baby 50 miles away.

Right, so the fact that you were there and the victims were

these anti-Dunwell protesters is just coincidence.

Well, there are conspiracy websites that say different, but yeah.

If this DNA isn't a match with Toby Holmes...

Sir, forget the DNA.

We found his shirt soaked in his wife's blood.

No, you didn't, Spence.

DC Goodman.

- It's Harry from Central Lab, on one. - Okay, thanks.

Harry, what news?

We've just had the third degree from anti-terrorist operations.

They're convinced it was an inside job.

- You're kidding. - There is a silver lining.

Our computer's pretty burnt up, the hard drive looks okay.

Okay, great. Well, bring it over. I've got a salvage package

I half know a way around.

I don't think ATO are going to be too happy about that,

taking stuff off-site.

- Harry, did you start the fire? - No.

No. So don't feel guilty about it.

It's your computer. You don't want it rotting away

in some evidence room for six months,

at least not until you've saved the data.

Now, hard drives are like kidnap victims.

The first 24 hours are golden.

Christ, Felix, you could sell ice to the Eskimos.

Thank you, Harry.

So, you want the Cherry Tree Farm DNA?

Just bring it over.

Okay, so it wasn't Toby Holmes's sweatshirt.

- It doesn't make him innocent. - It makes him look a lot less guilty

and the theory it was planted a lot more credible.

Why? He borrowed it

because he knew removing his wife's face was going to get messy.

So he goes to that trouble, then he takes the shirt home

and dumps it in the first place that anybody's going to look?

- He tried to burn it. - And makes a very bad job of it.

He shoved her wedding ring down her throat, for God's sake.

Sir, you have no idea how much I wish we hadn't got that call,

that I didn't have that memory of what I saw in that room.

I believe you, Spence, but it doesn't mean that Toby Holmes is guilty.

Why don't you start from the start?

I just ran a sweep. Nothing.

Good.

- Why is it taking you so long? - Almost there.

When we ID'd the bodies, it threw up the restraining order on Toby Holmes.

It turns out he had broken it very publicly the night before.

- At the Dunwell protesters' meeting. - Yeah.

He's breaking his restraining order!

- How long have you been working on this? - Tell me about the arrest.

Toby Holmes lived in the original mansion on the hill.

We couldn't get an answer so we had a poke around

and found the blood-stained sweatshirt in his incinerator.

Who found the sweatshirt, you or Tom McQueen?

Me. I smelt the smoke.

Then we saw movement in the house, so we put the door in.

We arrested him, questioned him,

and by lunchtime, CID officers from Norwich had taken over.

So you never doubted Toby Holmes's guilt?

- No. - Yeah...

- Hi. - Yesterday morning,

Spence got an email from a McQueen Security, which he deleted.

Must be his old AEC partner, Tom McQueen.

And it looks like they hooked up last night.

Okay, thanks.

So, tell me about Tom McQueen.

You and he were friends after he left the force.

He didn't leave, he was pushed, as you well know.

Yeah, he killed a kid while undercover, right?

He killed a crack addict who tried to stab him with a vial

while his drug dealer brother held him down.

From what I hear, he could've got clear without killing either of them.

Says who, hm?

Some bloke in a suit from the Police Complaints Commission?

Are you still in touch or not?

He lives in Cornwall now, has done for the last five, six years.

- When did you last see him? - Why?

Answer the question.

Not lately, all right?

Okay, Dr Foley. We'll need you to check your bag in,

plus any jewellery, keys, loose change,

and, sorry, we'd better have your shoes as well.

Okay.

- What size are you? - Five.

This is Stella Goodman from the Cold Case Unit.

I just wanted to check if you'd heard reports

of a virus similar to the W32 Hybris on the Met networks.

Probably just my colleague being paranoid. Thanks.

Thanks.

Hello, Dr Grace Foley, Cold Case squad.

Your lawyer did tell you I was coming?

I'm not saying anything in front of him.

Don't listen to him.

Okay, could you take the handcuffs off and leave us alone?

- Sorry? - You heard.

I'm not actually allowed to leave you alone with the prisoner.

Well, you are, 'cause I'm a mental health professional,

so I’ll just sign a disclaimer on the way out.

Can I speak to you for a minute?

This man bit the face off a colleague of mine.

- Why do you want to take the risk? - I want him to talk to me.

Then you'll have to sign the disclaimer up front.

Okay, well, let's rustle one up, shall we?

Take a look at the log.

At three o'clock this morning, your access card was used

to gain entry to the evidence room.

- What? - Do you have any recollection of that?

No.

Could anyone have borrowed your access card?

No.

You started celebrating your birthday last night a little early.

- Who were you partying with? - None of your business.

I'm trying to help, Spence.

I'm trying to help.

Where's your access card now?

This may cheer you up a little bit.

The DNA profile may yet still be salvageable.

Good.

- Let me know. - Will do.

Thank you.

He wants revenge

because he was friends with the guard I hurt.

The rapist.

Oh, the face-biting was just self-defence?

Or would have been if it'd done any good.

It just made him more angry.

Sometimes I curse my good looks.

- Did you file a complaint? - Yes.

Home Secretary's reading it now. Can I borrow your pen?

I like doodling when I'm talking.

No, I'm sorry, I may need it for notes.

How about a paper clip?

I've got papers all over my room.

You know very well I can't give you anything.

The privacy and the handcuffs is all I can do.

Privacy?

Actually, now you mention it,

it does seem very private in here all of a sudden.

I bet I could do something truly unspeakable and no one would know!

Oh, you really pissed him off.

He's gone on his tea break.

I'm not afraid of you.

Good for you.

You loved her, didn't you?

Well, you must have done, because you broke your restraining order

in front of everyone.

- Yeah, you want to fight? - Please, call the police!

Yes, you were drunk and you called her a slut,

but I think what you really meant to say was, "I miss you and I want you back."

That was an insulting gear change, Grace.

Not as insulting as a subtle one.

I'll tell you what else is insulting. You've been here five minutes

and you haven't mentioned my affidavit yet.

- My lawyer didn't give you a copy? - No, he didn't.

I don't believe you. I explicitly asked him to.

Well, he didn't. I'm sorry.

If you've read it and you're trying to trip me up...

I haven't seen an affidavit, all right?

That little shit.

That little shit.

Why don't you just give me a gist of what it contains?

Why don't you do your research before you come here wasting my time?

Don't blame me because you've got a bad lawyer.

For what it's worth, he didn't want me to come here today.

So don't give him the satisfaction of sending me away empty-handed.

- Hello? - Tom, it's me.

- Fancy some lunch? - Yeah, why not?

- Come by to pick me up? - Sure.

Meet me in Caplan Street

so you don't have to come through security, okay?

- Okay. - All right, see you in a bit.

Right.

I did love her. I loved... that face.

I could never have hurt that face.

I did two stupid things that evening. I made a scene.

And then I tried to say sorry for making a scene.

To Jackie?

I drove up there.

When you say there, you mean Cherry Tree Farm?

Is this the affidavit your lawyer is sitting on?

He only thinks I'm digging myself in deeper.

Okay. Well, let's just forget about your lawyer for a moment.

He was lying in the passage behind the front door.

And Jackie?

In the sitting room.

Stretched across the floor.

Her...

Her head was at a strange angle, but she...

- She looked peaceful. - Peaceful?

Like she could wake up any second, except she was cold.

So cold.

So her face...

No, he must have done that later. Either he came back or...

or he was hiding in the house, I didn't hang around.

- You didn't call the police? - Well, they were dead.

But you loved her.

- Are you calling me a coward? - No, I'm just saying

I think you should have called somebody.

Look, I was under a restraining order

which I had already broken once that evening.

I've called her a slut in public, for Christ's sake.

Yes, and there it was, written up on the wall, "slut".

No, it wasn't.

But nice try, Grace.

No, they were just lying there.

And you're right, I was a coward

and a terrible husband

and I deserve my fate.

Did you hear what I said?

I deserve my...

Yeah. Got some ID?

Cheers.

Will you take your helmet off, please?

- All right? - Yeah, it's all right.

Cheers.

Spence?

Anytime you want to talk about this, you know...

Yeah.

- You want to grab some lunch? - No, no, no, I'm fine.

- Are you sure? - Yeah, yeah, yeah, I'm cool.

All right, Spence?

- All right. - How's it going?

Good, good.

- You want one of these? - Yeah, sure.

So Tom, was it a coincidence you turning up on my doorstep last night?

- It was your birthday, you berk. - It's my birthday today.

Obviously I'm missing something.

Well, I was definitely missing something at three o'clock this morning.

What are you on about?

Someone used this to access our evidence store at CCU.

Specifically, evidence from Cherry Tree Farm.

- Cherry Tree Farm? - Yeah.

- You're not opening it up again? - My boss is.

And you think I knew that?

I think someone used my card this morning and it wasn't me.

Let's have a look at it.

Yeah, this is crap. This is bollocks.

The only entry systems worth shit are fingerprint and voice.

This is just a bar code.

Somewhere there's a directory and someone's got your number.

I couldn't find your toilet last night, let alone navigate half of West London.

But if I was minded to break into your office, believe me,

you wouldn't know I'd been.

I don't believe this.

Jesus, how long have we known each other?

Don't, I'm gonna cry.

Spence, I'm not lying to you.

If you want me to believe you, I need some answers.

To what?

To things I was too stupid, naive, or too intimidated to ask back in '88.

No, first we sort this out.

Do you believe me or not? It's important.

Shit.

The anonymous caller who found the bodies,

why was that never looked into?

Who was it?

For God's sakes, Tom, we were partners.

They were under surveillance, Security Services.

Why?

They had half the woolly hats under ops. Maggie just didn't like them.

- How did you know? - Because they tried to recruit me.

Bill Drake had me in for tea and biscuits with a paunch in a raincoat.

Was I interested in any extra curricular activities, cash in hand.

- Drake was on the news this morning. - Was he?

What, has he finally caught a terrorist?

Yeah, right.

You were always a star pupil.

Fuck of a lot of good it did in the end.

Who was the raincoat? MI5?

He asked the questions.

Was I a communist? Were my friends communists?

Had I ever met a communist? It was priceless.

I guess you had to be there.

- Spence... - Did they want to infiltrate?

They already had a mole in Shut Down Dunwell,

so they wanted me to set up an anti-Dunwell group

and cross-contaminate.

I couldn't see myself spying on innocent people,

no matter how cranky and deluded.

How did Drake take you knocking him back?

Said he respected my decision.

When I got the axe, he didn't exactly come to my rescue.

- Hi. - Hi.

Did I hear you say your colleague's bringing his damaged hard drive over?

Yeah.

- When is he coming? - Any minute. Why?

Well, if you need a hand salvaging it, let me know.

So, MI5 had Marcus Coulter and Jackie Holmes under surveillance

at the time of the murders?

Yeah, I assume not at the exact time.

'Cause they would've done something about it, right?

- Yeah. - So what happened, then?

Did they have the night off? Toby Holmes let their tyres down?

Look, I just got a call. I didn't know any details.

You knew a lot more than me, considering we were supposed to be partners.

Hey, come on, Spence, lighten up.

So, they told you where to find the bodies, yeah?

What about the sweatshirt in Toby Holmes's incinerator?

You found that, remember?

Anyway, fast-forward 18 years and you're scaling a greasy pole

and I'm on green-jumper-security-work- when-I-can-get-it street.

Maybe you had more to do with that than you'd like to think.

You're right to be pissed off, Spence.

But we both know we got our man.

We smelt it on him.

- Hey, birthday boy. - Hey.

Yeah, Jordan.

Spence, can you come in here for a minute, please?

- Hi. - Hi.

Where have you been?

- You're following me. - You lied to me.

You said you hadn't seen McQueen lately.

What did you tell Stella to do?

I saw Penny Coulter on her way out but Stella said no, I'm mistaken,

she's a witness to a robbery she's working on.

It's my decision when I tell you about a case, isn't it?

You kept me in the dark in case I had something to hide.

- And do you? - No, I do not.

- You should have consulted me first. - Why?

Respect. Loyalty.

- Professional courtesy. - Yeah, okay, okay, okay.

But this is a double murder inquiry.

You think whoever came in here went on to Central Lab

because they didn't find what they were looking for?

A light fixture with a bloodstain on it, yeah,

got the address on the back, all they needed was the directions,

it was in the evidence room.

- Tom McQueen? - What about him?

Would he be worried if any new evidence came to light?

No, not to my knowledge.

He wouldn't do that. He wouldn't destroy evidence, no.

Spence, I've delayed notifying the Central Lab investigation team

about what happened here. Did you know about it?

- No. - Because I believe McQueen did it.

But if he didn't do it,

then you did or the two of you did it together.

Or someone with an override pass who knew my number

and keyed it in manually.

Like who? Like who? Like who? Come on.

If I don't get to the bottom of what happened here, the truth,

then the pair of you are going to be turned over to Commander Drake.

Drake was our boss at AEC.

- Your boss? - Tom McQueen was his blue-eyed boy.

McQueen did tell me a couple of things I didn't know.

MI5 had Jackie Holmes and Marcus Coulter under surveillance

and they also had a mole in the Shut Down Dunwell group.

Toby Holmes admits to being at the crime scene?

Around 11:30. They were both dead.

He insists that Jackie Holmes's face was intact, not even a scratch.

Felix is going to get the path report.

And what do you think?

Well, I can't see any reason he had to lie.

Why wait so long?

Well, after he was sentenced, he mounted three separate appeals.

If he'd admitted belatedly that he was at the scene...

Yeah, it would have jeopardised his appeal. Yeah, I understand that.

He only signed the affidavit after he was transferred to Birch Hill.

- For biting the guard's cheek off. - Yeah.

I suppose he felt he had nothing to lose.

Cheek, face? What about it?

Well, there could be a connection, yes,

but I feel it's more to do with a man who's very angry

because he's been sentenced for a crime he never committed.

Yeah, there'd be no reason to break in,

try and get the light fixture with the bloodstain,

- if he's guilty. - No.

Did he mention anything about making an anonymous phone call?

He mentioned not making any.

So that must have been made by the surveillance team

who were watching the protesters' group, MI5.

- MI5? - Yeah, I know, I know.

Spencer just told me MI5 had a team

watching the anti-Dunwell protesters' group,

and there was also a mole that they'd put inside,

right? An informer.

What I don't understand is

if this surveillance team were watching the group,

how come they didn't see who killed Jackie Holmes and Marcus Coulter?

I don't know.

But...

maybe the informer made the anonymous call

and maybe it's the informer we should be looking for.

- Hi. - Hi. I'm looking for Felix.

I'll walk you through.

Okay. Right.

To prevent any additional damage

the first step is to create an image of the drive using an imaging tool.

Sorry, is the damaged drive the drive containing the operating system?

Yes, I think it is.

In that case, it's best not to boot the drive up

but replace it with a fresh one.

Really?

Install a new operating system and reconnect the old drive as a slave unit.

Well, sounds like you know more than the IT guys.

I learned a few tricks on secondment in the Fraud Squad.

- Would you like me to have bash? Felix? - Yeah, be my guest.

I'll be a few minutes.

Okay, right, we'll leave you to it. Should we get a coffee?

Penny Coulter's here.

I thought Grace was taking the interview?

Yeah, she's starting, then I want you to join us, okay?

Why?

Because she's your witness... I don't need to say anything.

- Just get there. - Can you give me five minutes?

- I'm just salvaging the drive. - Now!

You know there were a dozen witness statements

about the Shut Down Dunwell meeting at the plant in June 1988.

As you would expect,

their focus was on the confrontation between Toby Holmes and his wife

and your husband.

But we have three witness statements

which mention the looks you were giving Jackie Holmes during her speech.

She took everything that meant anything to me.

She did it so bloody

innocently.

So you were wearing your heart on your sleeve?

Yes, I suppose so.

And what's a political cause next to a broken heart?

It's nothing, is it, Penny?

Did somebody notice what you were going through?

Did they use it to their advantage?

What?

Penny, we know there was a mole inside the organisation.

We know Marcus Coulter and Jackie Holmes were under surveillance.

- Well, you're not suggesting... - Yes.

That is what I'm suggesting.

Who would ever suspect the founder of the organisation?

I'm sorry.

And you had the perfect cover, didn't you?

- This is ridiculous. - When you were called,

all you had to do was play the role of the jealous wife.

- I'm not listening to this. - Excuse me, Grace.

This is one big guilt trip for you, isn't it?

While you were watching these people, while you were spying on them,

you saw who actually killed them. Isn't that what happened?

Is that what all this is about?

Okay, you're in.

Any idea where we'll find the Cherry Tree Farm profile?

Oh, God. Without an operating system...

- Were you working on it last night? - Yeah.

Okay, right, well, we'll sort by date order.

There's our profile.

Okay, right. Well, before I open it, I need to save it to the hard drive.

And can we print a command history, just in case it dies on us?

Yeah, good idea.

I was recruited by a private detective called Clifford Day,

a horrible, weaselly little man.

Said he worked for MI5 and that he'd seen intelligence that proved

Marcus was planning something with some Spanish eco-terrorists.

- So what was this something? - Tunnelling into Dunwell.

Strictly against our anything- as-long-as-it's-legal mantra.

So the way Clifford Day sold it to you,

it would be them that was betraying the organisation, not you.

Even then, I'm not sure I really believed that.

I still had a front door key.

I'd go in and poke about while they were out.

Yes!

- You got a match? - What?

I've spoken to Boyd, everything's cool.

Well, he didn't pass that on.

He didn't have time, he's in an interview.

He said you were trying to pull the Cherry Tree Farm DNA

from a damaged hard drive. Is this it?

I'm not discussing this with you until I've spoken to Boyd.

Felix, I did not break into your evidence store last night, okay?

I'll see for myself. Excuse me.

Clifford Day.

Thanks.

You didn't mention a break-in last night, Felix.

It was more like an unauthorised access.

Yeah, but the same night Central Lab burns down?

How did you communicate with Day?

I'd phone in reports of significant events to Day's office.

What, like meetings of the anti-Dunwell group?

Yeah. The last one I ever made was the night of the murders.

So you spoke to him that night?

Yeah. I eventually got hold of him on his car phone.

- What time was it? - Eleven, eleven-thirty.

I think there was someone else with him.

I'm sure I could hear another voice in the background.

Man or woman?

- A man. - Could have been the radio.

So, you told Day everything that happened at that meeting that night,

about the confrontation, about him calling Jackie a slut?

Yes.

Yes, I did.

- Felix? - Hmm?

Look at this.

"Temp recovery now? No."

Just looks like someone's trying to corrupt this.

Yeah, Spence.

Felix has got a match on the Cherry Tree Farm DNA.

- And? - It's a Clifford Day, 50 years old.

He got done for drink driving five years ago. I'm picking him up now.

- You got the address from the DVLA? - Yeah.

And I checked back to '88 as well.

He lived in Norwich, only 30 miles from the Cherry Tree Farm.

I don't want you going in there unaccompanied, okay? Do you hear me?

We know who Clifford Day is. Penny Coulter was a mole

and he was her handler.

Spence, you're not going in there alone. Spence?

- Shit. - What?

Sorry, it's my mum.

Felix. Felix.

Get some water! Get some water!

It's the book!

There's been a chemical attack. I need a team of paramedics now.

Yeah, right now.

One, two, three, lift.
