(DCI Ford) Interview with Calvin Dunn

of 64 Elderwood Close, Ealing.

Mr Dunn is here voluntarily,

he is free to leave the interview at any time.

The date for the recording is February 11th, 2004.

You're actually recording this?

(DCI Ford) Uh, Home Office pilot scheme.

Recording and filming, belt and braces.

-You don't mind? -I don't mind.

(chuckles)

-Oh, do you mind? -Don't tell my SIO.

(lighter clicks)

(breathes deeply)

Now that we're all comfortable, how can I help?

(uneasy music)

So, just screams, Control?

Did the caller happen to say where in the woods

they heard these screams?

(DCI Ford) We were discussing your whereabouts on the night

of Tuesday, January 22nd, 2004.

Tuesday, um...

Lynn has book group. So it's my night to stay home.

You're not technically allowed to call it babysitting

if they're yours, are you? (scoffs)

(DCI Ford) How many kids have you got, Mr Dunn?

Oh, Calvin, please.

Uh, Lee's eight and Mia's four. My little sweet pea.

(DCI Ford) Can anyone confirm that you were at home that night?

Ask Lee if you want, he'll tell you.

Talk your legs off, that lad.

(DCI Ford) Do you know St Margaret's Church on Pond Lane?

It's barely a mile from your house.

St Mag's? Mm.

It's, um, it's up by High End Woods?

(uneasy music continues)

What the hell is that?

(ominous music)

(DCI Ford) We found dead birds hanging outside St Margaret's.

(scoffs)

Is that funny?

It is to me, love. Yeah.

(DCI Ford) Detective Constable actually.

DC Ford.

Why's that funny?

Well, some mad bastard's killed four people

and you're worried about a few birds?

Whole world's gone mad.

They're cutting off heads in Iraq.

You see that, DC Ford?

They're cutting them off,

and they're sticking them on spikes.

It's just kind of quaint to be worried about

the little birdies, isn't it?

(uneasy music)

(door creaks)

(DCI Ford) Your car was noted by the verger at St Margaret's

on... four occasions this last month.

Yeah. I saw that bald git giving me the evils.

I park there sometimes

when I'm going to Blockbuster for the kids.

The Parade's no stopping now,

and the church parking's always empty.

(DCI Ford) So you didn't go into the church?

No, I did once.

I was feeling a bit low.

(clicks tongue, inhales sharply) I was looking for God, I suppose.

(sniffles)

But God wasn't there.

(uneasy music continues)

(Spencer) Sir?

Are you okay, sir?

(Patel) Sir?

I need you to turn around.

(music swells)

(indistinct chatter)

(phone rings)

-Ford. -(indistinct chatter over phone)

Yeah?

-It's not my concern. It's my-- -(indistinct chatter over phone)

-(Naziri) Where you going, Boss? -Homicide. Just in.

Everyone's coming, it's your send-off.

(DCI Ford) There's been a man found.

At St Margaret's Church. Pond Lane.

St Margaret's? That St Margaret's?

(Jack) You were up with the lark.

The verdict came in on the Harrison case.

I heard it at the coroner's court.

-(Jack) And...? -Guilty. Both of them.

-You did good. -(Nikki) Really?

They were 15 and 16 years old.

The victim was only 14.

I say we skive off for the afternoon, hmm?

Take a long lunch by the river.

Or... we could hop on a plane,

forget about this place for a week or three, hmm?

(soft chuckle)

(Aysha) Lee...

I'm not here to fight.

Have you seen this?

There are police all round St Margaret's Church.

No.

-(Jack) Here he is. -(Velvy) Uh, Dr Alexander.

Is it you or the Professor on call?

Uh, I'll take it.

It's a suspected homicide. Male, 30 to 40 years old.

-Uh, he's in a church in Ealing. -A church?

-Which one? -(Velvy) St Margaret's.

They think he was strangled, the ligature is still in place.

Red PVC clothesline. Knotted.

And the body was found in a kneeling position.

-Kneeling? -(Velvy) Yeah, what is it?

-Calvin Dunn? -That must be 20 years ago.

Can't be.

Uh, who's Calvin Dunn?

We'll tell you on the way.

-(uneasy music) -(indistinct chatter)

(camera shutter clicks)

(in Yiddish) Blessed by the true Judge.

(camera shutter clicking)

(in English) Uh, the first officers thought that he was stiff.

Does that help us narrow down when he died?

Sadly not.

Too many variables for rigor mortis

to give a postmortem interval.

No signs of struggle, no scrapes on the floor.

Police found no ID on him.

-(Nikki) What do you make of it? -(Jack) Hmm...

It's a distinctive knot.

We can check the database, see if anything similar comes up.

It's not similar. It's the same.

Same knot, same supplication pose.

-Even the same church. -(Jack) You know this case?

I took these pictures 20 years ago.

Right here.

I was a junior DC on the killings.

I'm DCI now. Jane Ford.

-Dr Alexander, pathologist. -Jack Hodgson, forensics.

This is our colleague Velvy Sheur.

You investigated Calvin Dunn?

Four victims, two male, two female,

were found strangled and placed in churches

in the West London area, 2003-2004.

A fifth woman was presumed abducted,

her body was never found.

There was a sixth attack. Dominic Johnson.

But he managed to get away.

What about Dunn? Didn't he disappear as well?

He was interviewed four times by different teams.

Never arrested.

By the time we matched his DNA to the crime scenes,

he was... (puffs)

...without a trace.

So he was never charged? Never tried?

You can't charge them if you don't have them.

And now you think he's back?

Could it be some sort of copycat?

(DCI Ford) We never released details of the ligature.

The type or the knot.

Well, I get why you're connecting this

to another case, but I can't.

I can only examine what I see here, now.

And I know what I see.

You find me the evidence,

I'll do the rest.

(light suspenseful music)

-(Jack) No broken nails? -Uneven.

But I don't think from the struggle.

No obvious defence wounds to his hands

and nothing around the ligature either.

Hands bound before the ligature applied.

Likely killed elsewhere, then brought here?

What's he weigh? About 70 KG?

Yeah? You'd take him under the arms,

drag him backwards, right?

No drag marks.

There's nothing on the threshold or the front door.

And he's got bare feet

and there are no abrasions on his heels.

Right, so maybe, you put him on your shoulder.

(tense music)

No. Too far.

Wouldn't do that. I can't see him, Nikki.

There's got to be a trace, got to be a trace.

What about this?

(suspenseful music)

-His jumper's orange, right? -(Nikki) Yeah.

(Jack) Come here.

He carried him through here on his shoulder.

(camera shutter clicking)

There's parchmentation around the ligature mark, here...

and all the way across to here.

(Gabriel) Generally, that suggests a peri-mortem injury.

The ligature abrasions follow a predictable pattern

of horizontal circumscription about the neck,

distinguishable from the marks left by, say, hanging.

No discoid bruising.

The hands were bound with a cable tie.

Presumably prior to the ligature being applied.

There are petechial hemorrhages in the eyes,

consistent with an asphyxial death.

Moving to the chest and the upper torso.

There's bruising consistent with a sustained assault.

(camera shutter clicking)

-Any ID yet? -Fingerprints came back negative.

(Nikki) Somewhere out there, people are missing him.

At least I hope so.

Family, friends...

It's like an echo, isn't it?

Down through time, on and on.

-We'll find out who he was. -We don't always.

(Gabriel) Hmm...

That's a bowline.

(Nikki) I didn't have you down as a boy scout.

I'm not. I sail.

The bowline is the king of all knots.

-Was Calvin Dunn ex-Navy? -I don't know.

I don't know or care about Calvin Dunn right now.

And I don't need him in my head.

(DCI Ford) Calvin Dunn.

35 years old in 2004.

Degree in Computer Sciences from Bracknell University,

married Lynn, a nursery school teacher.

Two kids, Lee and Mia.

Calvin was working for an American weapons tech company

-since 1998. -(Jack) Weapons tech? Doing what?

(DCI Ford) Never got a clear answer.

There's a theory going that whatever Calvin was doing

was so sensitive that someone made him disappear.

You said he was interviewed four times?

Mm. One of those interviews was with me.

Calvin had an alibi.

-A strong one. -His wife?

An eight-year-old boy.

His son, Lee.

We interviewed him back then too.

(DCI Ford) Do you know the difference

between telling the truth

and telling lies, Lee?

Why is it important to tell the truth?

You have to tell the truth, Miss.

-God wants you to be good. -(DCI Ford chuckles softly)

(DCI Ford) Did you learn that at school?

Dad says God sees everything.

(DCI Ford) Do you go to church?

Dad says it's between me and Him.

(DCI Ford) Him? You mean God?

You don't need a church to know what's right.

(DCI Ford) You were telling me

what you and your Dad were watching.

Millionaire.

First three of them didn't even get the easy questions right.

What is the "N" in NHS?

What animal is Disney's Donald?

Who picked a peck of pickled peppers?

Is... Daddy in trouble?

(DCI Ford) Why do you say that?

-He's helping us. -Find that lady?

I saw her on the news.

(Nikki) There's bruising in the strap muscles.

It's limited but that's not unusual with a ligature.

The larynx was fractured, consistent with strangulation.

Are you any closer to finding out who he was?

(DCI Ford clicks tongue) Calvin didn't have a type.

Men, women, young, old.

He never seemed to care who or what they were.

He seemed to select them for their availability.

Alone, isolated locations, late at night.

His last target was a young sex worker,

Dominic Johnson,

at Hammersmith Bridge.

But...

Dominic got away.

-And Calvin went to ground. -For 20 years.

(Jack) And then he just starts up again?

After that long?

(DCI Ford) They call it "cooling-off periods".

There was one who killed seven times,

stopped for 14 years,

then killed three more before they caught him.

I'm sorry, I've got to go.

Uh, did I say something to upset you?

You have to make assumptions to investigate.

If I make assumptions, I can't help your investigation.

If you're right and this is Calvin Dunn, what can we expect?

Last time, there was barely a month

between his first and fourth attack.

I don't have much time.

(Jack) So, where do you start?

(DCI Ford) Well, the things Calvin left behind.

The abducted woman, Zoe Beck.

-The survivor, Dominic... -(Jack) What about the son?

-Lee? -Could he be covering for him?

(DCI Ford scoffs)

You don't know Lee Dunn.

Hello, Lee.

What took you so long?

I went to the house. Aysha told me you'd moved out.

Yeah.

(door closes)

(Lee) What else did she say? Aysha?

She didn't have to. She's showing. (chuckles softly)

Six months, right?

She knew I didn't want kids.

That body they found at St Margaret's.

He did it, didn't he?

Well, we don't know who's responsible.

Well, was the body left there...

you know, like... (inhales deeply)

...like the others? (exhales deeply)

Has anything else happened

to suggest your father might be back?

-Oh, my God. -Lee?

Back?

He never went away. I--

I've been telling you this for... well, for years now--

-(DCI Ford) All right, Lee-- -No, no. It's not all right.

You haven't returned my calls for months.

I told you. I'm retiring.

From what? You gave up years ago.

(scoffs) Just...

(breathes deeply)

How's it going?

The ambulances?

I'm not doing crew anymore. I'm... MRU.

-(DCI Ford) Motorcycle Response? -Mm.

-On your own? -Prefer it that way.

Once people know who I am...

It's not easy being you, Lee.

I thought you could talk to Aysha.

I never wanted a kid. I told her that from the off.

(sombre music)

You're not your dad, Lee.

You prove that every day.

Every life you save.

(Lee) And Beck?

You told him?

Not yet.

(scoffs)

The poor bastard's been waiting 20 years.

He has a right to know if Calvin's back.

(breathes deeply)

(water boiling)

(phone vibrates)

(sighs)

(uneasy music)

(sighs)

(Jack over phone) Remember what I told you, right?

Consider everything.

-(Jack) Yes. But test little. -Yeah, yeah.

(Jack) Let me know how it goes, all right?

(rustling)

(tense sting)

(sighs)

(DCI Ford) The surviving witness mentioned leather gloves.

-Is it Dunn's? -We don't know yet.

And it hasn't been... lying there for years?

There are no signs of the disintegration you'd expect

from being on the woodland floor for a long period of time.

It's been there two weeks max, I reckon.

There was no trace of the Sahara dust

from the rain we had on New Year's Eve.

-And the DNA from that glove? -(Jack) Yeah. Mini taped and sent.

(DCI Ford) Okay. (inhales deeply)

And what about this?

The PVC ligature from the current victim

matches the clothesline used on the victims back then.

Not only that...

The PVC coating

was marked with an indent at regular intervals.

The shape of the groove on the current lig...

almost identical to the one Dunn used in 2004.

Oh, God.

I thought this was what you'd been waiting for?

It isn't that.

(DCI Ford) I understand

you want to stay out of it, but I need your help.

I have to go and speak to a man called Charles Beck.

-He used to be a pathologist. -Oh, I know who he is.

We read Beck at medical school.

And he examined

the first four victims on the Dunn case.

God, then wasn't his wife the fifth?

He did a lot of media for us

during the course of the investigation.

And then his wife went missing.

And she was never found?

I need to tell him about the new body at the church.

He'll have questions.

Questions that you can answer better than me.

(Nikki) I wonder what these are for.

(DCI Ford) Beck convinced himself

he could find Zoe where we couldn't.

Pollen tracking and hedgerow analysis...

-Forensic Botany? -Yeah.

He's considered quite the expert these days.

He gets calls from forces all over the world.

He doesn't do dead bodies anymore.

I mean, would you?

He's not here. We should go.

I know where he'll be.

(light suspenseful music)

(birds squawking)

(sighs)

(DCI Ford) Hello, Dr Beck.

This is Dr Alexander. She's from the Lyell Centre.

(Charles) Thomas Lyell's house of horrors.

(DCI Ford) I was hoping we could--

(Charles) Heard about the body at St Margaret's. You did the PM?

-That's right. -Birds hanging from the trees?

Ligature strangulation? Red clothesline?

Found posed kneeling towards the altar? Hmm?

(Charles) Who was he?

Well, DNA doesn't match with anyone

on the missing persons register or the--

I wasn't asking you. I was talking to a professional.

(Charles) You think it was his work?

Calvin Andrew Dunn?

I don't know.

It wasn't.

Dunn is dead.

You seem very sure.

(Charles) Why did he do it that way, Dr Alexander?

The churches, the supplication pose?

He wants to desecrate and defile a Holy Place.

So why go back to St Margaret's?

He'd already profaned it.

Even the church thought so, they closed it down.

Dr Beck has been... very generous with his theories.

They flooded this valley in 1973.

At its centre, Fordham is 100 feet deep,

you could hide a Chieftain Tank in there.

And my home is barely a mile away.

Defile, desecrate...

deprive.

You believe that Calvin Dunn put your wife's body

into the water, here?

(Charles) It was all about power with Dunn.

Depriving me of Zoe made him feel powerful.

We dredged the reservoir... several times.

I knew the Assistant Commissioner.

So they sent a couple of hobbyist frogmen to humour me.

I can't imagine how that must feel.

To live with that.

(Charles) Oh, I think you can.

You're like me, you live with a lot.

I think you know just how I feel.

(uneasy music)

If you want my once-expert advice,

you'd stop looking for Calvin Dunn.

He's dead.

I'd know if he wasn't.

Why birds? What's that about?

Lee says his dad used to take him camping.

They'd trap sparrows, just for the fun of it.

Power, like Beck says?

Killers often start with animals, don't they?

It's textbook.

But birds seem to mean something to him.

-(phone vibrating) -The little birdies?

(Nikki) Beck's wrong about one thing.

-What? -(Nikki) That glove...

(suspenseful music)

"Calvin Dunn's DNA was on the glove.

And his fingerprints in the lining."

Maybe he's not so dead.

You're interested now, aren't you?

Is it a sex thing? Do you think?

I mean, he's...

he's killing boys as well as girls, right?

(DCI Ford) Well, we're keeping an open mind

as to what the motive is behind the killing.

We're interviewing anyone

who was in the vicinity of St Margaret's, and...

asking for voluntary DNA.

But he leaves them in a church.

Do you go to church?

I'm sorry, Lee. You weren't supposed to see this.

Is that him?

That's what your father looks like now.

(DCI Ford) At least... according to AI.

Do I look like him?

(DCI Ford) It's not real, Lee.

Could you come with me? Come on.

I've been trying to get a hold of Mia.

The number on file is disconnected, and...

we never had an email for her.

Me and my sister don't talk.

Heard she got married. Has a baby now.

-(Lee scoffs) -But I need to talk to her.

What happens if your father tries to make contact?

He was never that bothered with Mia.

Lucky for her.

She was... too young to do what he said.

He used to tell me about this dream he had.

(uneasy music)

Him...

high above everyone and everything,

looking down from the clouds, like...

God Himself.

He doesn't have power over you anymore, Lee.

You don't have to be afraid.

You're bigger than him.

Stronger than he ever was.

I will never be free until you find him.

Please.

(kids chattering and laughing)

(uneasy music)

Mia?

I'm sorry, you've mistaken me for someone else.

My name's Jane Ford, I'm a police officer.

We met when you were much younger.

(soft sigh)

(Mia) I'm sorry.

-The place is a mess. -(chuckles)

I wish my place was this messy.

I like things tidy.

It drives Anton crazy.

(DCI Ford) Lee said he thought

you might have been working at a nursery?

(Mia) Oh. That...

(inhales deeply)

We decided I should leave.

Mia, if you ever need anyone to vouch for you--

We're very happy. Anton says we're blessed.

You are. Your baby's beautiful.

Thanks.

Is that why you're here?

-To... check on me and Emily. -What?

No, it's nothing like that...

It makes sense.

I mean, how do you know I'm not like him?

Like Calvin?

Lee was asking after you.

(DCI Ford) You might have heard the news...

I don't watch news, it's all bad.

Don't even have it on my phone.

Anton tells me if there's anything I need to know.

There was a body found at St Margaret's Church.

We can't rule out that your father is involved.

I don't have a father.

We don't talk about that man in this house.

I understand.

But I have to ask you.

Can you think of anywhere that he might be?

Did your mum ever talk about--

She never talked about him either.

I'm sorry about Lynn.

She did her best for us.

(baby crying)

I'm a good mum. I think.

I can see that.

(DCI Ford) Mia, don't worry about the police being around.

It's standard in the circumstances.

They're there for you.

Hmm?

-(DCI Ford) Take care. -(Mia) Thank you.

(light suspenseful music)

(sighs) Mind if we take a little break?

You must be knackered too.

What am I? Your tenth interview today?

(DCI Ford on video) Mm. Something like that.

Can I get you anything, Calvin?

Tea.

Three lumps. I get a bit of blood sugary.

(DCI Ford on video) Interview suspended 15:11.

(mouths)

(light tense music)

(startled grunt)

(mouths)

-(Jack) What? -(mouths)

(mouths)

(light suspenseful music)

(mouths)

-(mouths) -(Jack) Idiots.

He's calling the police idiots. (chuckles)

Brilliant. Thank you.

She lip-read it. He's calling the police idiots.

He's playing with them. He still is.

Maybe he left that glove on purpose.

Yeah.

Maybe he wants us to know he's back.

(Nikki) Cara shouldn't be watching that stuff, Jack.

-(Jack) Huh? -(keys jangling)

Ah, come on. I thought she was upstairs.

(Nikki) She shouldn't be around any of this.

Calvin Dunn targeted the pathologist's family.

That was a long time ago, Nikki.

Yeah.

Well, she's got a reading week coming up, and, uh...

her mum wanted her to come home, so...

I think that would be a really good idea. Don't you?

Yeah.

Hello?

Dr Beck?

(Charles) Whatever you're selling, I don't need it. Please go away.

-Oh. Sorry, Dr Beck... -You don't have an appointment.

I'd know if you had an appointment.

Now please, go away.

I'm Dr Alexander.

We met yesterday?

(Nikki) I'm from the Lyell Centre.

I did the postmortem on the body we found at St Margaret's Church.

Nikki, right?

Ah. Sorry. I don't get many visitors.

Why don't we go inside?

-(Charles) After you. -(Nikki) Thanks.

Old lab habits die hard. Please go through.

(Nikki) I heard about your work in Forensic Botany.

It's a fascinating field.

(Charles) I put up acres of netting,

but the buggers still get through.

Stomach contents create a map of how specific species

are digested at a cellular level.

Leaves, seeds, pollen.

(sighs)

You've come to talk to me about the body they found?

Why are you so convinced Calvin Dunn is dead?

Because I've studied him.

Four bodies on the table.

(Charles) A wife in the water.

"By their works, shall ye know them."

(Nikki) What do you know about him?

(Charles) That's why you're really here, isn't it?

I've no prurient interest in Dunn.

Everybody wants to know about Calvin, eventually.

I just want to understand the case as you saw it.

Uh, nobody found out much about him anyway.

He worked for the Americans,

something connected to the military.

At one point, the papers said that the Russians swooped in

to extract their key serial killer asset.

You've never thought of leaving this house?

(Charles) Because he was here?

He's still here.

You feel him, don't you?

I didn't want to give him the satisfaction.

-(Nikki) Even though he's dead. -(scoffs)

You want to know why I know he's dead?

He's dead because we haven't heard from him in 20 years.

A man like that can't stay silent.

We found a glove... with Dunn's DNA on it.

It was dropped near St Margaret's in the last few days.

(Charles) That's not possible.

You don't want it to be him, I understand that.

But we've made huge advances in forensics and DNA analysis

in the last 20 years.

(Charles) This would never have happened in my day.

-(Nikki) Sorry? -You've made a mistake.

Cross-contaminated evidence.

You outsource everything these days, don't you?

Listen, Charles.

Maybe there's a real chance of getting him this time.

That's what I thought then.

We spent so much time trying to understand him back then.

Every other cop was a profiler in 2004.

(Charles sighs)

(Charles) But the victims weren't his real work.

(Nikki) What do you mean?

It was us.

Me. The other families. Ford, even.

Then there's his own... car wreck of a family.

And now we're all talking about Calvin again.

A narcissist's fever dream.

"Psychopath with narcissistic tendencies".

That was the profiler's wisdom back then.

I understand your anger.

-(scoffs) -All these years, and no justice.

(Charles) Justice?

What's that then?

I don't know. Some sort of balance?

Punishing the perpetrator to acknowledge

the pain they've caused.

Restoring the moral order.

All with the bang of a judge's gavel?

Or an eye for an eye.

I can understand why you'd want that.

How can you ever extract a price

from someone who can never feel your pain?

How many years in a cage would be an adequate punishment?

(pensive music)

I sometimes think she's still here.

I don't want to forget.

I understand him really well.

And look what it's done to me.

(DCI Ford) What work did you do at Clearable Systems, Mr Dunn?

Ah, you're going to have to talk to them about that one I'm afraid.

Not allowed to. Made me sign an NDA.

(DCI Ford) And Clearable do a lot of work for the Pentagon.

Don't they?

(Calvin) Hmm.

(DCI Ford) Do you have a lot of secrets, Calvin?

Well, you're only as sick as your secrets, right?

You know, I worry about that sometimes.

My agreement means that...

I just can't even talk to my own family about what I do.

Do you talk to your boyfriend about your work?

DC Ford?

(Jack over phone) Any updates on Dunn?

No. I'm on my third day of live facial recognition.

When was the last reported sighting of him?

Calvin Dunn's been seen once a week

for the last 20 years.

From Moorgate to Manatoba.

(DCI Ford) Any news on the John Doe?

DNA from our guy at St Margaret's doesn't match

to anyone and nobody's called Clayman.

(Jack) Also, they've sent over the evidence boxes

from the historic crime scenes.

-I'll let you know what we find. -Yeah, thanks.

Let's go through the sightings again.

(groans) Crackpots and conspiracists?

It's like you've always told me.

If you can't find what you're looking for,

look again with your eyes open.

-Do I actually say that shit? -Mm.

Sorry, ma'am, a report of a break-in.

Look around you. This is a murder incident room.

Not Neighbourhood Watch.

It's at 14 South Hill Place.

(DCI Ford) That's Mia Dunn's house.

-(tense music) -(sirens blaring)

-This the point of entry? -And exit, most likely. Mm.

(DCI Ford) There's CCTV, let's review the footage.

-We're on it. -(DCI Ford) This could be Dunn.

(Jack) Mm-hmm.

(indistinct chatter over radio)

Come on, Mia.

I'm not going in there.

(DCI Ford) It's okay. I'm with you.

-He's in there. -No, he isn't.

I've been through every room.

-(DCI Ford) Come on. -(inhales sharply)

We don't know it was your father.

(Mia) I know.

The minute I walked in the door, I could smell him.

What?

It was him.

We start at the top, go through room by room,

and you just tell me if anything's moved

or if anything's missing.

-I don't want to. -It's all right.

(DCI Ford) Come on.

(uneasy music)

What's up there?

Nothing.

Mum's stuff.

(Jack) Right. What do you make of this then?

All right.

It's not opportunistic.

He's hiding his face, yeah?

(Velvy) Uh-huh.

He's done his homework, he knows where the camera is.

(phone vibrating)

Hello?

(man over phone) Sleep tight, sweet pea.

(ominous music)

What is it?

It's him.

Well, this is... this is live.

-(Jack) See that shadow? -(Velvy) What?

(Jack) There!

He's still here!

(suspenseful music)

(Jack) Hey!

Where did he go? I lost him.

Velvy, stay there. Can I get some help over here?

(man grunts)

-(suspenseful music continues) -Jack! Jack!

(Jack) Velvy! Wait!

(Velvy grunts)

-(Velvy groans) -(Jack) Velvy!

Jesus, Velvy...

-Velvy, are you okay? -(Velvy groans)

(Jack) Let me see you. Argh!

You okay?

I think that might be the most exciting thing

that's ever happened to me.

(Jack) Just stay there. Just stay still.

(Jack) Ford found these rubber overshoes

in Mia's attic.

Could be Calvin's.

The police always thought he was wearing

something like these.

He never left shoeprints.

Mia identified it as the one her dad bought for her mum.

The doting husband.

She killed herself, right? Lynn Dunn?

Yeah. Ford said...

she held it together until the kids left home.

Another victim of Calvin Dunn.

Velvy was lucky.

Don't look at me.

I didn't tell him to go haring after a killer.

No. He went haring after you haring after a killer.

(camera shutter clicks)

Scalpel, please, Doctor.

(Jack) Thank you.

Bit of light, please.

(Nikki) What is it?

(Jack) Come on.

Come on.

Where's Simone when you need her?

(Jack) I'll send it off to Forensic Botany.

I think I know a man who can help.

(Charles) Weissia rostellata. Beaked Beardless Moss.

It's on the Nationally Scarce list.

Rare is good.

(Charles) It's only ever been recorded

in one area of Greater London.

Why am I looking at this?

The moss was found in an overshoe belonging to Calvin Dunn.

(Nikki) From 20 years ago.

(Jack) Where in London? Where was the moss recorded?

She knows.

Fordham Reservoir.

I told you, he put her in the water

so that I'd never see her again.

(DCI Ford) It doesn't prove anything.

(Charles) The moss puts Dunn here.

(DCI Ford) My mum was here.

She had a picnic with her sewing circle.

What does that prove? Half of west London's been here.

We searched the reservoir as you insisted

and we found nothing.

Two divers, four days.

The water's 100 feet at its deepest,

you barely gave it a chance.

-The moss. Is that all you've got? -So far.

Is the species localised to this part of the shoreline?

(Charles) No, it's all over the reservoir, both banks.

(DCI Ford scoffs)

(DCI Ford) That's more than a square mile of water.

And as the good doctor said, it's 100 feet deep.

(DCI Ford) Even if there were human remains in there,

they've been there for years.

(Charles) And I've been telling you for years.

If the remains were wrapped and weighted,

they could still be intact.

-I've been telling her that too. -(DCI Ford) That's not the point.

No Chief Super is going to sign off

on the cost of a search of this scale based on a...

fragment of moss on a 20-year-old shoe.

The water level's dropped, hasn't it?

(Charles) Every year. The planet's heating up.

Don't know if you've heard about it.

So, 20 years ago...

The water would have been six feet higher.

Huh.

(pensive music)

So all this would have been underwater.

Over there.

(DCI Ford) What's over there?

In 2004, that's the only place

you'd have found Weissia rostellata.

It stretches all the way to the car park.

(Charles) The section of reservoir in front of the car park,

it's the deepest part.

He put her there. She's there.

(sighs)

(suspenseful music)

(Nikki) Charles?

You shouldn't be here.

(clicks tongue) Where else should I be?

(Nikki) This could take days. Weeks maybe.

-Why don't you wait at home? -(soft scoff)

And whatever I said to Ford,

we both know the chance of finding anything

after all this time is...

very slim.

(Charles) We used to sail here on the lake.

(Nikki) It must be hard to spend time here.

I was...

I was in court. A double murder.

At least I believed it was, uh, murder.

There was this young defence barrister,

thought she knew it all.

Took me on, totally shredded me on the physical evidence.

I felt like I'd been 12 rounds with Mike Tyson.

(sighs)

I was in the bar, drowning my sorrows.

Zoe walked in. She sat on the stool next to me.

She said, "You look like you need a drink."

I did.

So we did.

I was six Jamesons in before I realised

she was the QC that had mugged me.

She looked different without the lawyer's wig

and the terrifying snarl.

Three years before I could get her to marry me.

(Charles) Being the barrister she was,

she kept raising objections.

She was too young, I was too old.

Marriage was an outdated institution.

(sombre music)

She said we'd both seen too much to believe in human connection,

to believe that love could last in a world like this.

With all we'd borne witness to,

in court, in the mortuary...

I said it was because of that,

because of what we knew,

because we'd seen the worst of what the world could do that...

we had to prove it could be different.

That the world could be good.

It could be love.

That we could grow

without taking the air from each other.

I told her if we didn't believe in anything else,

we could believe in us.

(indistinct chatter)

(Charles) We were together ten years.

Every year seemed to prove that I was right.

(indistinct chatter)

(Charles) That you could grow closer,

that love could... get deeper.

And that...

even though we would have to deal with a world

that was... violent...

a world that was cruel, we could try and make it better.

(dramatic music)

I told her we'd... we'd built a life that was...

loving and real.

(dramatic music continues)

I told her we were safe.

(music stops)

I was wrong.

(gloomy music)

(siren blaring in distance)

(Nikki) Poor Charles.

(DCI Ford) Really?

The body was wrapped in the sail from Charles Beck's boat.

We had CCTV on Zoe Beck with bruises all over her face.

-The day before she disappeared. -What?

We asked him about it. He claimed she got them sailing.

But plenty of people told us it was stormy between them.

You think he was violent towards her?

The rest of Dunn's victims were posed and presented.

Only Zoe's body was hidden.

Are you serious?

I'm not the only one who thought it.

(DCI Ford) Could the pathologist have used his knowledge

of Calvin Dunn's killings to get rid of his own wife?
