Interview with Calvin Dunn
of 64 Elderwood Close, Ealing.
Mr Dunn is here voluntarily.
He is free to leave
the interview at any time.
Date for the recording
is February 11th 2004.
You're actually recording this?
Yeah. Home Office pilot scheme.
Recording and filming.
Belt and braces.
You don't mind?
I don't mind.
Oh, do you mind?
Don't tell my SIO.
Well, now that we're all comfortable,
how can I help?
So just screams, Control?
Did the caller happen to say
where in the woods
they heard these screams?
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?
How many kids have you got, Mr Dunn?
Oh, Calvin, please.
Lee's eight and Mia's four.
My little sweet pea.
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.
Do you know St Margaret's
Church on Pond Lane?
It's barely a mile from your house.
St Mag's?
Hmm. It's, um
It's up by High End Woods.
What the hell is that?
We found dead birds hanging
outside St Margaret's.
It's not funny.
It is to me, love. Yeah.
Detective Constable, actually.
DC Ford.
Why is that funny?
Well some mad bastard's
killed four people
and you're worried about a few birds.
The whole world's gone mad.
They're cutting off heads in Iraq.
Did you see that, DC Ford?
They're cutting them off
and they're sticking them on spikes.
It's kind of quaint
to be worried about
little birdies, isn't it?
Your car was noted by
the verger at St Margaret's
on four occasions this last month.
Hmm. Yeah, I saw that bald git
giving me the evils.
I park there sometimes
when I get a Blockbuster's for the kids.
The Parade's no-stopping now,
and the church parking's always empty.
So you didn't go into the church?
No, I did once.
I was feeling a bit low.
I was looking for God, I suppose.
HE SNIFFS
But God wasn't there.
MALE PC: Sir?
MALE PC: You OK, sir?
FEMALE PC: Sir!
I need you to turn around.

Ford.
Detective Chief Inspector,
a body's been found.
Yeah?
Suspected homicide.
It's not my concern. It's my
The body was found in St Margaret's
Church, Ealing.
- Where are you going, boss?
- Homicide. Just in.
Everyone's coming. It's your send-off.
There's been a man found
in St Margaret's Church, Pond Lane.
St Margaret's?
That St Margaret's?
FOOTSTEPS APPROACH
You were up with the lark.
The verdict came in on the Harrison case.
Heard it at the Coroner's Court.
And?
Guilty.
Both of them.
- You did good.
- Really?
They were 15 and 16 years old.
The victim was only 14.
What do you say we skive off
for the afternoon, huh?
Take a long lunch by the river.
Or we could hop on a plane.
Forget about this place
for a week or three. Hmm?
Lee.
I'm not here to fight.
Have you seen this?
There are police all around
St Margaret's Church.
No
Here he is.
Dr Alexander, is it you
or the professor on call?
I'll take it.
It's a suspected homicide.
Male, 30 to 40 years old.
He's in a church in Ealing.
A church? Which one?
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?
What is it?
Calvin Dunn.
That must be 20 years ago.
Can't be.
Who's Calvin Dunn?
Tell you on the way.
Baruch dayan ha'emet.
The first officers thought
that he was stiff.
Does that help us narrow down
when he died?
Sadly not.
Too many variables for rig or mortis
to give a postmortem interval.
No signs of a 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.
I'll 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 Schur.
You investigated Calvin Dunn?
Four victims - two male, two female -
were found strangled
and placed in churches
in the west London area,
2003 to 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
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?
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.
JACK: No broken nails?
Uneven, but I don't think
from a struggle.
No obvious defence wounds to his hands,
and nothing around the ligature either.
Hands bound before ligature applied?
Likely killed elsewhere, then
brought here.
What does he weigh?
About 70kg?
Yeah? He'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 put him on his shoulder.
Nah. It's too far.
Wouldn't do that.
I can't see him, Nikki.
Got to be a trace. Got to be a trace.
How about this?
His jumper's orange, right?
NIKKI: Yeah.
Come here.
I think he carried him
through here on his shoulder.
There's parchmentation around
the ligature mark here
and all the way across to here.
Generally, that suggests
a perimortem injury.
The ligature abrasions follow
a predictable pattern
of horizontal circumscription
about the neck,
distinguishable from marks
left by, say, hanging.
No discord bruising.
Hands were bound with a cable tie,
presumably prior to
the ligature being applied.
There are petechial
haemorrhages in the eyes,
consistent with an asphyxial death.
Moving to the chest and upper torso.
There's bruising consistent
with a sustained assault.
Any idea yet?
Fingerprints came back negative.
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.
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.
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?
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.
Mmm. And 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.
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.
Did you learn that at school?
Dad says God sees everything.
Do you go to church?
Dad says it's between me and him.
Him? You mean God?
You don't need a church
to know what's right.
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's the "N" in NHS?
What animal is Disney's Donald?
Who picked a peck of pickled peppers?
Is Daddy in trouble?
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?
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?
Then he just starts up again
after that long?
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.
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?
The last time, there was barely
a month between his first
and fourth attack.
I don't have much time.
So where do you start?
The things Calvin left behind.
The abducted woman - Zoe Beck.
The survivor - Dominic.
What about the son?
Lee?
Could he be covering for him?
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.
What else did she say?
- Aysha.
- Well, she didn't have to.
She's showing.
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.
And was the body left there?
You know, like..
Like the others?
Has anything else happened
to suggest your father might be back?
- Oh, my God.
- Lee
Back?!
He never went away.
I've been telling you this for years now.
- All right
- 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.
HE SCOFFS
How's it going?
The ambulances.
I'm not doing crew any more. I'm MRU.
- Motorcycle response.
- Hmm.
On your own?
Prefer it that way.
Once people know who I am
You know, it's not easy being you, Lee.
But I thought you could talk to Aysha.
I never wanted a kid.
I told her that from the off.
You are not your dad, Lee.
You prove that every day.
Every life you save.
And Beck?
You told him?
Not yet.
That poor bastard's
been waiting 20 years.
He has a right to know if Calvin's back.
PHONE VIBRATES
JACK ON PHONE: Remember
what I told you, right?
Consider everything.
- Yes, but test little.
- Yeah, yeah.
Let me know how it goes, all right?
RUSTLING
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's no trace of the Sahara dust
from the rain we had on New Year's Eve.
And the DNA from that glove?
Yeah. Minitaped and sent.
OK.
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
in 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.
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.
I know who he is.
We read Beck at medical school.
And he examined the first
four victims on the Dunn case.
God. And 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.
I wonder what these are for.
Beck convinced himself he could
find Zoe where we couldn't.
Pollen tracking.
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 any more.
I mean, would you?
He's not here.
We should go.
I know where he'll be.
FORD: Hello, Dr Beck.
This is Dr Alexander.
She's from the Lyell Centre.
Thomas Lyell's house of horrors.
I was hoping we could
Heard about the body in
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?
Who was he?
DNA doesn't match
with anyone on
the Missing Persons register
I wasn't asking you. I was
talking to a professional.
Do you think it was his work,
Calvin Andrew Dunn?
I don't know.
It wasn't.
Dunn's dead.
You seem very sure.
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 100ft 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?
BECK: 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.
Oh, I think you can.
You're like me. You live with a lot.
I think you know just how I feel.
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 said his dad used to take him camping
and 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 VIBRATES The little birdies.
Beck's wrong about one thing.
What?
That glove.
"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?
FORD: Oh, 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 a 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,
at least according to Al.
Do I look like him?
It's not real, Lee.
Could you come with me? Come on.
I've been trying to get hold of Mia.
The number on file is disconnected,
and we never had an email for her.
Me and my sister don't talk.
She got married.
There's a baby now.
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.
Him - high above everyone and everything.
Looking down from the clouds
like God himself.
He doesn't have power over you
any more, 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.
Mia?
I'm sorry. You've mistaken me
for someone else.
My name is Jane Ford.
I'm a police officer.
We met when you were much younger.
I'm sorry. The place is a mess.
BOTH LAUGH
I wish my place was this messy.
I like things tidy.
Drives Anton crazy.
Lee said he thought you might
have been working at a nursery.
Oh that.
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.
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,
and we can't rule out
that your father was 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 CRIES
I'm a good mum
I think.
I can see that.
Mia, don't worry about
the police being around.
It's standard in the circumstances.
They're there for you.
FORD: Mmm?
- FORD: Take care.
- MIA: Thank you.
Might we take a little break?
You must be knackered too.
What am I, your tenth interview today?
FORD: Something like that.
Can I get you anything, Calvin?
Tea.
Three lumps.
I get a bit blood-sugary.
FORD: Interview suspended 15.11.
HE MOUTHS
What?
HE MOUTHS
Idiots?
He's calling the police idiots.
Brilliant. Thank you.
She lipread 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.
Cara shouldn't be watching
that stuff, Jack.
Huh? Oh, come on.
I thought she was upstairs.
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 her mum wanted her
to come home, so
I think that would be
a really good idea, don't you?
Yeah.
Hello.
Dr Beck?
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?
I'm from the Lyell Centre.
I did the postmortem on the body we found
at St Margaret's Church.
Nikki, right?
Sorry. I don't get many visitors.
Why don't we go inside?
- After you.
- Thanks.
Old lab habits die hard.
Please, go through.
I heard about your work
in forensic botany.
It's a fascinating field.
I put out 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.
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.
My wife in the water.
"By their works shall you know them.”
NIKKI: What do you know about him?
That's why you're really here, isn't it?
I have no prurient interest in Dunn.
Everybody wants to know
about Calvin eventually.
I just want to understand
the case, as you saw it.
Well, 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?
Because he was here?
He's still here.
You feel him, don't you?
I didn't want to give him
the satisfaction.
Even though he's dead?
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've found a glove
with Dunn's DNA on it.
It was dropped near St Margaret's
in the last few days.
Oh
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.
This would never have happened in my day!
- 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.
The victims weren't his real work.
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.
A psychopath
with narcissistic tendencies.
That was the profilers' wisdom back then.
I understand your anger.
All these years - no justice.
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 adequate punishment?
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.
FORD: What work did you do at
Clearable Systems, Mr Dunn?
Oh, you're going to have to talk to them
about that one, I'm afraid.
I'm not allowed to.
Made me sign an NDA.
Hmm. Clearable do a lot of work
for the Pentagon, don't they?
Do you have a lot of secrets, Calvin?
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: 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 Manitoba.
Any news on the John Doe?
DNA from our guy at St Margaret's
doesn't match to anyone. Nobody's
called to claim him.
Also, they 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.
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?
- Mmm.
- Sorry, ma'am.
- A report of a break-in.
- Look around you.
This is a murder incident room,
not a neighbourhood watch.
It's at 14 South Hill Place.
FORD: That's Mia Dunn's house.
SIRENS WAIL
This the point of entry?
And exit, most likely.
There's CCTV. Let's review the footage.
We're on it.
- This could be Dunn.
- Mmhm.
Come on, Mia.
I'm not going in there.
It's OK. I'm with you.
He's in there.
No, he isn't.
I've been through every room.
Come on.
We don't know it was your father.
I know.
The minute I walked
in the door, I could smell him.
What?
It was him.
FORD: If 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.
Come on.
What's up there?
Nothing.
Mum's stuff.
Right, what do you make of this, then?
Right
It's not opportunistic.
- He's hiding his face, look.
- Uh-huh.
He's done his homework.
He knows where the camera is.
PHONE VIBRATES
Hello?
MAN: Sleep tight, sweet pea.
What is it?
It's him.
Oh, this is This is live.
JACK: See that shadow?
- What?
- There.
He's still here.
Hey!
Where did he go? I lost him.
Velvy, stay there.
Can I get some help over here?
Jack?
Jack!
JACK: Velvy!
Wait!
VELVY GROANS
Velvy!
Jesus, Velvy. Velvy, are you OK?
Let me see you. Argh!
Are you OK?
I think that might be
the most exciting thing
that's ever happened to me.
Just stay there.
Just stay still.
JACK: Ford found these rubber
overshoes in Mia's attic.
Could be Calvin's.
Police always thought he was
wearing something like these.
Never left shoe prints.
Mia identified it as the one
her dad bought for her mum.
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.
Scalpel, please, Doctor.
Thank you.
Bit of light, please?
NIKKI: What is it?
Come on. Come on.
Hmm.
Where's Simone when you need her?
Send it off to forensic botany.
I think I know a man who can help.
BECK: Weissia rostellata.
Beaked beardlessmoss.
It's on the nationally scarce list.
Rare is good.
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 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.
FORD: It doesn't prove anything.
BECK: The moss puts Dunn here.
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 100ft 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?
No, it's all over
the reservoir. Both banks.
That's more than a square mile of water.
And as the good doctor said,
it's 100ft deep.
Even if there were
human remains in there,
they've been there for years.
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.
- 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?
BECK: Every year. Planet's heating up.
Don't know if you heard about it.
So, 20 years ago
The water would have been
six feet higher.
Huh.
So all this would have been underwater.
Over there.
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.
The section of reservoir in front of
the car park
is the deepest part.
He put her there.
She's there.
NIKKI: Charles
You shouldn't be here.
Where else should I be?
This could take days.
Weeks, maybe.
Why don't you wait at home?
And whatever I said to Ford,
we both know the chance
of finding anything
after all this time is
very slim.
BECK: 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 a murder.
There was this young defence barrister -
thought she knew it all.
Took me on.
Totally shredded me
on the physical evidence.
Felt like I'd been 12 rounds
with Mike Tyson.
I was in the bar, drowning my sorrows.
Zoe walked in and 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.
It was three years before
I could get her to marry me.
Being the barrister she was,
she kept raising objections.
She was too young. I was too old.
Marriage was an outdated institution.
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 that 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
the world could do,
that we had to prove
it could be different.
The world could be good
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.
We were together ten years.
Every year seemed to prove
that I was right.
We could grow closer,
the 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.
I told her we'd built a life that was
loving and real.
I told her we were safe.
I was wrong.
NIKKI: Poor Charles.
FORD: Really?
The body was wrapped in a sail
from Charles Beck's boat,
and we had CCTV on Zoe Beck
with bruises all over her face
the day before she disappeared.
What?
We asked him about it.
He claims 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.
FORD: Could the pathologist
have used his knowledge
of Calvin Dunn's killings to get
rid of his own wife?

Interview with Calvin Dunn
of 64 Elderwood Close, Ealing.
Mr Dunn is here voluntarily.
He is free to leave
the interview at any time.
Date for the recording
is February 11th 2004.
You're actually recording this?
Yeah. Home Office pilot scheme.
Recording and filming.
Belt and braces.
You don't mind?
I don't mind.
Oh, do you mind?
Don't tell my SIO.
Well, now that we're all comfortable,
how can I help?
So just screams, Control?
Did the caller happen to say
where in the woods
they heard these screams?
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?
How many kids have you got, Mr Dunn?
Oh, Calvin, please.
Lee's eight and Mia's four.
My little sweet pea.
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.
Do you know St Margaret's
Church on Pond Lane?
It's barely a mile from your house.
St Mag's?
Hmm. It's, um
It's up by High End Woods.
What the hell is that?
We found dead birds hanging
outside St Margaret's.
It's not funny.
It is to me, love. Yeah.
Detective Constable, actually.
DC Ford.
Why is that funny?
Well some mad bastard's
killed four people
and you're worried about a few birds.
The whole world's gone mad.
They're cutting off heads in Iraq.
Did you see that, DC Ford?
They're cutting them off
and they're sticking them on spikes.
It's kind of quaint
to be worried about
little birdies, isn't it?
Your car was noted by
the verger at St Margaret's
on four occasions this last month.
Hmm. Yeah, I saw that bald git
giving me the evils.
I park there sometimes
when I get a Blockbuster's for the kids.
The Parade's no-stopping now,
and the church parking's always empty.
So you didn't go into the church?
No, I did once.
I was feeling a bit low.
I was looking for God, I suppose.
HE SNIFFS
But God wasn't there.
MALE PC: Sir?
MALE PC: You OK, sir?
FEMALE PC: Sir!
I need you to turn around.

Ford.
Detective Chief Inspector,
a body's been found.
Yeah?
Suspected homicide.
It's not my concern. It's my
The body was found in St Margaret's
Church, Ealing.
- Where are you going, boss?
- Homicide. Just in.
Everyone's coming. It's your send-off.
There's been a man found
in St Margaret's Church, Pond Lane.
St Margaret's?
That St Margaret's?
FOOTSTEPS APPROACH
You were up with the lark.
The verdict came in on the Harrison case.
Heard it at the Coroner's Court.
And?
Guilty.
Both of them.
- You did good.
- Really?
They were 15 and 16 years old.
The victim was only 14.
What do you say we skive off
for the afternoon, huh?
Take a long lunch by the river.
Or we could hop on a plane.
Forget about this place
for a week or three. Hmm?
Lee.
I'm not here to fight.
Have you seen this?
There are police all around
St Margaret's Church.
No
Here he is.
Dr Alexander, is it you
or the professor on call?
I'll take it.
It's a suspected homicide.
Male, 30 to 40 years old.
He's in a church in Ealing.
A church? Which one?
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?
What is it?
Calvin Dunn.
That must be 20 years ago.
Can't be.
Who's Calvin Dunn?
Tell you on the way.
Baruch dayan ha'emet.
The first officers thought
that he was stiff.
Does that help us narrow down
when he died?
Sadly not.
Too many variables for rig or mortis
to give a postmortem interval.
No signs of a 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.
I'll 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 Schur.
You investigated Calvin Dunn?
Four victims - two male, two female -
were found strangled
and placed in churches
in the west London area,
2003 to 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
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?
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.
JACK: No broken nails?
Uneven, but I don't think
from a struggle.
No obvious defence wounds to his hands,
and nothing around the ligature either.
Hands bound before ligature applied?
Likely killed elsewhere, then
brought here.
What does he weigh?
About 70kg?
Yeah? He'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 put him on his shoulder.
Nah. It's too far.
Wouldn't do that.
I can't see him, Nikki.
Got to be a trace. Got to be a trace.
How about this?
His jumper's orange, right?
NIKKI: Yeah.
Come here.
I think he carried him
through here on his shoulder.
There's parchmentation around
the ligature mark here
and all the way across to here.
Generally, that suggests
a perimortem injury.
The ligature abrasions follow
a predictable pattern
of horizontal circumscription
about the neck,
distinguishable from marks
left by, say, hanging.
No discord bruising.
Hands were bound with a cable tie,
presumably prior to
the ligature being applied.
There are petechial
haemorrhages in the eyes,
consistent with an asphyxial death.
Moving to the chest and upper torso.
There's bruising consistent
with a sustained assault.
Any idea yet?
Fingerprints came back negative.
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.
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.
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?
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.
Mmm. And 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.
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.
Did you learn that at school?
Dad says God sees everything.
Do you go to church?
Dad says it's between me and him.
Him? You mean God?
You don't need a church
to know what's right.
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's the "N" in NHS?
What animal is Disney's Donald?
Who picked a peck of pickled peppers?
Is Daddy in trouble?
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?
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?
Then he just starts up again
after that long?
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.
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?
The last time, there was barely
a month between his first
and fourth attack.
I don't have much time.
So where do you start?
The things Calvin left behind.
The abducted woman - Zoe Beck.
The survivor - Dominic.
What about the son?
Lee?
Could he be covering for him?
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.
What else did she say?
- Aysha.
- Well, she didn't have to.
She's showing.
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.
And was the body left there?
You know, like..
Like the others?
Has anything else happened
to suggest your father might be back?
- Oh, my God.
- Lee
Back?!
He never went away.
I've been telling you this for years now.
- All right
- 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.
HE SCOFFS
How's it going?
The ambulances.
I'm not doing crew any more. I'm MRU.
- Motorcycle response.
- Hmm.
On your own?
Prefer it that way.
Once people know who I am
You know, it's not easy being you, Lee.
But I thought you could talk to Aysha.
I never wanted a kid.
I told her that from the off.
You are not your dad, Lee.
You prove that every day.
Every life you save.
And Beck?
You told him?
Not yet.
That poor bastard's
been waiting 20 years.
He has a right to know if Calvin's back.
PHONE VIBRATES
JACK ON PHONE: Remember
what I told you, right?
Consider everything.
- Yes, but test little.
- Yeah, yeah.
Let me know how it goes, all right?
RUSTLING
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's no trace of the Sahara dust
from the rain we had on New Year's Eve.
And the DNA from that glove?
Yeah. Minitaped and sent.
OK.
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
in 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.
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.
I know who he is.
We read Beck at medical school.
And he examined the first
four victims on the Dunn case.
God. And 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.
I wonder what these are for.
Beck convinced himself he could
find Zoe where we couldn't.
Pollen tracking.
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 any more.
I mean, would you?
He's not here.
We should go.
I know where he'll be.
FORD: Hello, Dr Beck.
This is Dr Alexander.
She's from the Lyell Centre.
Thomas Lyell's house of horrors.
I was hoping we could
Heard about the body in
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?
Who was he?
DNA doesn't match
with anyone on
the Missing Persons register
I wasn't asking you. I was
talking to a professional.
Do you think it was his work,
Calvin Andrew Dunn?
I don't know.
It wasn't.
Dunn's dead.
You seem very sure.
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 100ft 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?
BECK: 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.
Oh, I think you can.
You're like me. You live with a lot.
I think you know just how I feel.
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 said his dad used to take him camping
and 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 VIBRATES The little birdies.
Beck's wrong about one thing.
What?
That glove.
"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?
FORD: Oh, 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 a 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,
at least according to Al.
Do I look like him?
It's not real, Lee.
Could you come with me? Come on.
I've been trying to get hold of Mia.
The number on file is disconnected,
and we never had an email for her.
Me and my sister don't talk.
She got married.
There's a baby now.
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.
Him - high above everyone and everything.
Looking down from the clouds
like God himself.
He doesn't have power over you
any more, 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.
Mia?
I'm sorry. You've mistaken me
for someone else.
My name is Jane Ford.
I'm a police officer.
We met when you were much younger.
I'm sorry. The place is a mess.
BOTH LAUGH
I wish my place was this messy.
I like things tidy.
Drives Anton crazy.
Lee said he thought you might
have been working at a nursery.
Oh that.
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.
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,
and we can't rule out
that your father was 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 CRIES
I'm a good mum
I think.
I can see that.
Mia, don't worry about
the police being around.
It's standard in the circumstances.
They're there for you.
FORD: Mmm?
- FORD: Take care.
- MIA: Thank you.
Might we take a little break?
You must be knackered too.
What am I, your tenth interview today?
FORD: Something like that.
Can I get you anything, Calvin?
Tea.
Three lumps.
I get a bit blood-sugary.
FORD: Interview suspended 15.11.
HE MOUTHS
What?
HE MOUTHS
Idiots?
He's calling the police idiots.
Brilliant. Thank you.
She lipread 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.
Cara shouldn't be watching
that stuff, Jack.
Huh? Oh, come on.
I thought she was upstairs.
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 her mum wanted her
to come home, so
I think that would be
a really good idea, don't you?
Yeah.
Hello.
Dr Beck?
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?
I'm from the Lyell Centre.
I did the postmortem on the body we found
at St Margaret's Church.
Nikki, right?
Sorry. I don't get many visitors.
Why don't we go inside?
- After you.
- Thanks.
Old lab habits die hard.
Please, go through.
I heard about your work
in forensic botany.
It's a fascinating field.
I put out 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.
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.
My wife in the water.
"By their works shall you know them.”
NIKKI: What do you know about him?
That's why you're really here, isn't it?
I have no prurient interest in Dunn.
Everybody wants to know
about Calvin eventually.
I just want to understand
the case, as you saw it.
Well, 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?
Because he was here?
He's still here.
You feel him, don't you?
I didn't want to give him
the satisfaction.
Even though he's dead?
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've found a glove
with Dunn's DNA on it.
It was dropped near St Margaret's
in the last few days.
Oh
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.
This would never have happened in my day!
- 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.
The victims weren't his real work.
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.
A psychopath
with narcissistic tendencies.
That was the profilers' wisdom back then.
I understand your anger.
All these years - no justice.
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 adequate punishment?
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.
FORD: What work did you do at
Clearable Systems, Mr Dunn?
Oh, you're going to have to talk to them
about that one, I'm afraid.
I'm not allowed to.
Made me sign an NDA.
Hmm. Clearable do a lot of work
for the Pentagon, don't they?
Do you have a lot of secrets, Calvin?
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: 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 Manitoba.
Any news on the John Doe?
DNA from our guy at St Margaret's
doesn't match to anyone. Nobody's
called to claim him.
Also, they 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.
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?
- Mmm.
- Sorry, ma'am.
- A report of a break-in.
- Look around you.
This is a murder incident room,
not a neighbourhood watch.
It's at 14 South Hill Place.
FORD: That's Mia Dunn's house.
SIRENS WAIL
This the point of entry?
And exit, most likely.
There's CCTV. Let's review the footage.
We're on it.
- This could be Dunn.
- Mmhm.
Come on, Mia.
I'm not going in there.
It's OK. I'm with you.
He's in there.
No, he isn't.
I've been through every room.
Come on.
We don't know it was your father.
I know.
The minute I walked
in the door, I could smell him.
What?
It was him.
FORD: If 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.
Come on.
What's up there?
Nothing.
Mum's stuff.
Right, what do you make of this, then?
Right
It's not opportunistic.
- He's hiding his face, look.
- Uh-huh.
He's done his homework.
He knows where the camera is.
PHONE VIBRATES
Hello?
MAN: Sleep tight, sweet pea.
What is it?
It's him.
Oh, this is This is live.
JACK: See that shadow?
- What?
- There.
He's still here.
Hey!
Where did he go? I lost him.
Velvy, stay there.
Can I get some help over here?
Jack?
Jack!
JACK: Velvy!
Wait!
VELVY GROANS
Velvy!
Jesus, Velvy. Velvy, are you OK?
Let me see you. Argh!
Are you OK?
I think that might be
the most exciting thing
that's ever happened to me.
Just stay there.
Just stay still.
JACK: Ford found these rubber
overshoes in Mia's attic.
Could be Calvin's.
Police always thought he was
wearing something like these.
Never left shoe prints.
Mia identified it as the one
her dad bought for her mum.
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.
Scalpel, please, Doctor.
Thank you.
Bit of light, please?
NIKKI: What is it?
Come on. Come on.
Hmm.
Where's Simone when you need her?
Send it off to forensic botany.
I think I know a man who can help.
BECK: Weissia rostellata.
Beaked beardlessmoss.
It's on the nationally scarce list.
Rare is good.
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 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.
FORD: It doesn't prove anything.
BECK: The moss puts Dunn here.
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 100ft 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?
No, it's all over
the reservoir. Both banks.
That's more than a square mile of water.
And as the good doctor said,
it's 100ft deep.
Even if there were
human remains in there,
they've been there for years.
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.
- 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?
BECK: Every year. Planet's heating up.
Don't know if you heard about it.
So, 20 years ago
The water would have been
six feet higher.
Huh.
So all this would have been underwater.
Over there.
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.
The section of reservoir in front of
the car park
is the deepest part.
He put her there.
She's there.
NIKKI: Charles
You shouldn't be here.
Where else should I be?
This could take days.
Weeks, maybe.
Why don't you wait at home?
And whatever I said to Ford,
we both know the chance
of finding anything
after all this time is
very slim.
BECK: 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 a murder.
There was this young defence barrister -
thought she knew it all.
Took me on.
Totally shredded me
on the physical evidence.
Felt like I'd been 12 rounds
with Mike Tyson.
I was in the bar, drowning my sorrows.
Zoe walked in and 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.
It was three years before
I could get her to marry me.
Being the barrister she was,
she kept raising objections.
She was too young. I was too old.
Marriage was an outdated institution.
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 that 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
the world could do,
that we had to prove
it could be different.
The world could be good
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.
We were together ten years.
Every year seemed to prove
that I was right.
We could grow closer,
the 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.
I told her we'd built a life that was
loving and real.
I told her we were safe.
I was wrong.
NIKKI: Poor Charles.
FORD: Really?
The body was wrapped in a sail
from Charles Beck's boat,
and we had CCTV on Zoe Beck
with bruises all over her face
the day before she disappeared.
What?
We asked him about it.
He claims 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.
FORD: Could the pathologist
have used his knowledge
of Calvin Dunn's killings to get
rid of his own wife?
