Silent Witness (1996–…): Season 15, Episode 2 - Death Has No Dominion: Part 2 - full transcript

'My sister Mary, a forensic
scientist, was murdered by
a crack addict at a crime scene

'the police were supposed
to have secured.'

You want us
to take on Chesham's pathology work?

Well in a word, yes.

The way the Buckinghamshire Police
scapegoated Lizzie is appalling.

Lizzie Fraser committed
suicide this afternoon.

It is a bad one. Yeah.
They've entrusted it to a humble DI
who's six months along.

I almost envy her. Her shock.
Ever since Dad I feel...

Numb.

Mick worshipped Jessie.

He would've done everything
to save her.



This is the Wraith inquiry.
It is indeed.

DNA evidence suggests
she likes working with men.

Weak, needy people
she can manipulate.

Was there anyone up there with you,
at the farm? The devil.

The devil was up there with me.

First impressions?

From a pathology angle,
she's strikingly varied.

Strangulation, stabbing,
execution-style shooting.

Have you ever had a good suspect?

Eliminated suspects, A-Z.

Out of 35,000 women,
only nine closely resembled Janet's
profile but DNA ruled them out.

None of them were the Wraith.

Who does Janet think
you're looking for?

She's a thrill seeker of the most
dangerous kind



and the biggest kick of all
is embroiling the weak

and the needy in her crimes.

Killing by remote control.

So the petrol he used to start the
fire - that belonged to Mick, right?

It was an unusual alkylate type
which matched the stuff in Mick's
chainsaw,

so it's probably. Shouldn't you be
sitting down. No, I'm fine.

And the, erm, the bike D-lock
he put around Luke's neck.

We know that belonged to Mick how?

SOCO gave the serial number to the
manufacturers... Who matched it
to Mick's details. Of course.

The burglary was carefully planned,
but the rape was feverishly
improvised.

Why do you think they went to such
lengths to secure Mick and Luke?

Couldn't this woman, the Wraith,

couldn't she have stood guard
over them with a stun gun?

He's a tough guy, ex-SAS.
Why take the risk?

At the postmortem you said
the welts on Mick's wrists

Tough guy, ex-SAS. I don't know...
That makes him shockproof?

I don't know. Look, we don't even
know the Wraith was standing guard.

What, you think she went into the
house with the killer and Jessie?

You think she witnessed the rape?

At the killing of PC Amar
she got in the car with the gunman.

I just can't get my head around
a woman having anything to do
with this.

Do you want to get a drink
or something?

Aye, later would be nice. Later?

I need to make a house call first.
Parents of PC Amar.

I don't want them hearing about
the link to the farm murders
on the news.

What, you want me to...
Only if you've nothing better to do.

My goodness.

So...

there's no question it's her?

We found her DNA.

It'll be all over the news tomorrow.

We wanted you to be prepared.

Thank you, Tom.

So... she's killed a child now?

Yeah.

Why? What does she want?

To get our attention.

But why?!

Hey...

It'll be all right, Nasreen.

It'll be all right.

The victims... at the farm.

Were they...

Were they shot, like Maalik?

We can't get... No.

No, they weren't shot.

They were strangled...

and stabbed.

It's very important that you don't
divulge those details to anyone.

It could jeopardise
a future conviction. Of course.

All our conversations
are in confidence.

Nasreen and Khalid understand that.

Why wouldn't she use the gun?

Why would she change her MO?
Khalid, please, don't.

Stop trying to think like a copper.
It doesn't help.

I've got to do something.
I can't just...

I can't just sit here all day!

I have...

a question... if I may.
Khalid... Please. No.

It's all right. What is it, Khalid?

Are you sure Karl Basharov
didn't kill my son?

Khalid, please, don't.
I'm so sorry.

It's a valid question.

Her DNA was in that car.

DNA doesn't lie.

I'm sorry.

Now, one day soon,
her luck will run out...

and I'll be there.

I give you my word.

Are you OK?

Fine. Sorry.

You've lost someone recently?

My dad.

How long?

A month. Bit more...

And now all the formalities
have come and gone

and you still can't grieve for him.
Yeah.

It's this work.

Dries us up.

Shrivels our hearts
and we don't even know it.

But it will come out in the end,
has to.

When?

My wife died of breast cancer
last year.

I wasn't there...

at the end.

I was in Glasgow tracking down some
woman we were sure was the Wraith.

I'm sorry.

When this is all over...

this case...

it'll hit me. I know it will.

I'm almost looking forward to it.

Daddy!
Hey, little man! Are you all right?

How are you doing?
Are you all right? Yeah...

Still not convinced that the Wraith
was there, are you?

DNA evidence...

Is it infallible?

Properly collected, labelled and
processed, it's pretty bloody close.

You've just listed three areas
where human error could occur.

True. But this DNA was found inside
the pipe in the form of blood,

so... when, how?

Well, no offence,
but sometimes scientists screw up.

Look at the mosque bomber case.

From what I hear that was as much
the fault of over-zealous coppers
as Chesham Lab

and Professor Fraser is no longer
here to defend herself.
OK, I'm sorry. It was a bad example.

But accidental contamination -
it's possible, isn't it?

It's possible. It's always...

What?

The swab I used to lift the blood
off the pipe was...

different.

Different from what? Different
packaging. Different manufacturer,
not the one we normally use.

Is that significant? I don't know.

What?

We inherited these swabs.
From where?

Chesham Labs.

Why's that?
We've been doing their work
while they're under review

and they've been showing
their gratitude by giving us
stocks and supplies

because, well,
they're broke, basically.

The swabs are sealed.
Could someone at Chesham have
contaminated them? Oh, very easily.

These big labs buy swabs wholesale
in their thousands.

They're then re-sterilised
and packed in individual sealed bags

and then boxed, in batches of 24
but there is always a 25th swab

which is never opened
unless contamination's suspected.
The control swab?

We must test the control swab
from the batch which picked up
the Wraith's DNA.

Shouldn't we be testing
all the swabs from Chesham?

That's where Byrne
and the Wraith inquiry have done
all their testing?

Far too expensive. I can order tests
on two batches, maybe three.
That's it.

Then let's hope we get lucky.

Who is Karl Basharov?

I knew you were going
to ask me that.

Like you said,
we don't work in isolation.

PC Amar's death prevented him
testifying at the trial
of a Russian people trafficker.

Basharov?

What was he on trial for?
Murder.

Amar's testimony was critical
in so much as he'd seen Basharov

at a location where we later found
two Estonian girls shot in the head.

Did Basharov beat the charge?

CPS dropped the case
when Amar was killed.

Mission accomplished, then.

Basharov was not behind
Maalik Amar's death.

Maalik's father didn't seem so sure.

Couldn't Basharov have paid
the Wraith to do the hit?

The witness testimony motive
seems very strong.

Basharov only came over from Moscow
three years ago and he brought
his own people with him.

A small-time female drug addict?

Wouldn't even be on his radar.

What so Amar's death was just
a massive stroke of good luck?

For Basharov? So it would seem.

Well, I need to go home,
get some sleep.

The briefing's at 5am, right?

If you can make it. Yeah, of course.

Night. Night.

I was just about to call you.
'Ah, great minds. You OK?'

'Nikki?'

I think we need to talk to Janet.

What's going on?

Long story. Hi, Janet.

The murder of PC Amar
reads like a professional hit.

Two shots to the head,
one shot to the chest,

and all the shell-casings
were removed from the car.

OK? Well, compare that with
the overkill of Ray Carpenter

and the incompetent, almost tentative
nature of the Meg Stiles murder.

Well, Meg Stiles was her
first victim.

Nevertheless... It feels like the
work of three different killers?
From a pathology perspective, yes.

But, I mean, you profiled her,
so I assume you understand her
psychologically?

Hang on, have you all come here
to question Janet's findings?

Leo, it's all right. I can see
where they're coming from.

My profile was based on what
I was told by the police...

that DNA made it a scientific
certainty the same woman

either committed these crimes
or was present at their commission.

So the question for me wasn't,
is this the work of one person,
but only, could I reconcile

such differing crimes?
And you could?

Yes. I profiled her as
an intelligent high-functioning
heroin addict

with extensive criminal connections
who was addicted not only to drugs

but to all forms of risk,
specifically the baiting
of authority.

So the peaks and troughs
of her addiction produced...

correspondingly diverse
crimes in terms of organisation?

And in terms of motive. She killed
Meg Stiles for drug money,

PC Amar to rile the police and the
overkill visited on Ray Carpenter...

that betrayed a gleeful sadism.

So the only commonality was
there was no commonality?

I would dispute that. All three
murders evince a sociopathic
narcissist who lives for kicks.

These latest murders
I can't speak for because
I don't know the details.

And you never felt like you were
tailoring the foot to the shoe?

OK, enough. If you're suggesting
the Wraith's crimes were...

It's possible that the DNA
linkage was flawed. Flawed?!

Well, how?

As a result of... long-term
contamination at Chesham Lab.

Tom Byrne.

'Sir, it's me.

I don't know what kind of face
Dr Alexander's putting on for you

but it's not her real one.

And DI James is still
very much on the team.

Go home, Ginny, get some rest.

You see conspiracies
round every corner.

All the physical evidence
suggests Ash Tree Farm

was the work of a lone male killer.

The one thing that doesn't
is DNA found on a swab

we inherited from Chesham Lab,

the same lab where the majority
of these Wraith DNA hits were found.

Hang on. Just back up, will you?

What is there to suggest
exactly that these common female DNA
hits are not genuine?

There was a very strong alternative
suspect for the murder of PC Amar.

And not to speak out of turn
but we do know something went awry

at Chesham with the mosque bomber
forensics.

Control swabs exist precisely to
expose this kind of contamination.

In every case where
the Wraith's DNA was found,

the control would've been tested

and if it'd come up positive
for DNA, anybody's DNA,
we would've known about it.

Agreed?

We don't have an explanation, Leo.
I'm just suggesting that maybe
we dig a little deeper.

OK.

OK, tomorrow I'm taking Lizzie's
husband Greg down to Chesham lab

to clear out her office.

It's not still under review?
The physical inspection was
completed last week.

I've arranged for Simon Avery to let
us in, so while I'm helping Greg,

why don't you have a word,
air your concerns?

Our concerns.

Hello, Greg. Simon, hi.

Simon, hi. Why the entourage?

Detective Inspector James has been
working closely with Harry.

What's going on?
Is this to do with the review?

It's just something
we need to get to the bottom of.

Could you open up Lizzie's office
and we'll have a talk? Yeah, sure.

I'm afraid there's quite
a bit to sort out.

Knowing Lizzie, that's the
understatement of the bloody year.

This sounds redundant now, Leo,
but, erm...

I can't tell you how much Lizzie
appreciated y-you stepping into help.

Of course.

You know, she came back that night,
she was just so relieved, you know.

She was kind of hopeful she'd turned
a corner on the whole...

bloody mess.

She loved this one.

Oh, yes.

I'm sorry, Greg.

I know what you're going through.

We were together for 19 years,
Simon!

We had children!
There is no comparison!

I was offering compassion.

Not comparisons.
Simon, could you rustle up some tea?

Then Harry and DI James
can ask their questions.

Sure...

God!

"I was offering
compassion... not comparisons."

What was all that about?
Ancient history, really.

What did he mean by "no comparison"?

I used to go out with Lizzie's
younger sister Mary.

She was a forensic scientist.
She was murdered at a crime scene.

At a crime scene?

Mm. The police were supposed
to have secured.

I was at the scene.
She died in my arms.

I'm sorry.

It was a long time ago.

And as Greg says
"there's no comparison".

Thanks.

Let me get this straight.

You're seriously positing that
the Wraith's DNA came from the swab
rather than the pipe?

We're exploring that possibility.
Right.

Would you be exploring it
if the swab came from your lab
rather than mine? Course not.

Well, why not?

Because this is where all the Wraith
DNA samples have been detected
since 2000.

Not all. The majority. You take
my point. Yes, I think I do.

You're questioning
the integrity of that detection.

In the light of a case like
Ash Tree Farm we have to, I think.

Well, as you've made a link
with the Wraith Inquiry

I take it you're working
with Detective Superintendent Byrne?

We briefed him already
about Ash Tree Farm.

Right, so he knows you're here.

You're working with his inquiry?
What's your point?

Well, simply that DSI Byrne
and I have discussed the possibility
of contamination before.

You have?

Yes.
Many times, in fact, over the years.

So many crime scenes, so far apart,
so diverse.

The relative scarcity of female
killers. And?

I've always been able to reassure
him on two key points.

One, the control swabs in all
the cases where the Wraith's DNA

has been found have tested
negative for DNA,

if it's the Wraith's or otherwise.

Two, all female staff with access
to the lab have had their DNA

compared with the Wraith's.

No match.

Business or pleasure?

Think carefully before answering.
Wrapping up my case.

Which part of "your investigation has
been subsumed into our inquiry"
was ambiguous to you?

Have you not got better things
to do?

You disobeyed an order from a senior
officer and you're obstructing a live
inquiry. Such bullshit! Don't.

Expect a summons from the Borough
Commander's office within 24 hours.

And give your Federation rep
a call if I were you.

Stupid, stupid!

Hello?

Yeah.

Right, thanks.

Negative? Negative.

There's two sets of shoeprints
in the blood.

Mick's and a pair of size 12
Kevlar mine boots. No third set.

She kept her distance.
But that doesn't fit with her blood
being found inside the pipe

that suggests she was in the thick
of the struggle.

So...

where are her shoeprints?

I don't know.

But, as you say,
her blood was found inside the pipe.

She was here.

Inciting the rape of a woman?

Killing a child?

You think someone would do that
just to goad the police?

Why not? She's killed a cop.

So what's left?

How do you up the ante,
raise the stakes?

Same reason she gravitated
from heroin to crack cocaine.

Monstrous escalation.

And to come back down to earth
for a moment...

her DNA was discovered
at two different labs.

Twice in Buckinghamshire
and once in Suffolk.

And there's no one person who has
worked at or who has access to both.

How many other crimes
does DNA suggest she committed
with male accomplices?

A dozen or so, and always guys
lower down the criminal food chain.

And none of them, bar one,
has ever identified her or given you
a description? No.

Why not?

Because they're more afraid of her
than they are of me.

I'm not a cold-blooded killer.

I can't.

Come on, Lee.

You've had fun with Mum.

Now it's time to clean up.

I can't do it.

Do it!

Do it!

Lee, breakfast!

Coming, Mum.

It's my fault.

Don't flatter yourself.

No-one talks me into anything
I don't want to do.

You want to get a coffee
or something? Yeah, OK.

Oh, shit. No, sorry, I can't.
Never mind. Another time.

No. No, no, I, erm...
I've got to be at the hospital.

I decided I should find out
what colour baby-grows to buy.

Fire engines or fairies? Yeah.
I've left it a bit late.

So...

Who's Dad? Yeah, well...
Where's Dad? Yeah.

I wanted a baby too much for it to
be dependent on finding Mr Right.

Good for you. So...?

So I've got a mate with a high IQ
and great cheek bones...

and he was kind enough to oblige.

OK.

What are friends for.

You're shocked. No, I'm not.
Yes you are! I'm not!

My dad had the exact same expression
when I told him. I'm cool.

I am down with it. I mean,
I f-feel a bit for the guy
with the cheekbones

but apart from that...

I'm going to cancel.

Oh, bollocks, you are!
I'll come with you...

if you like. Or maybe not.
Yeah, no...

I'd like that very much.
Right. Good.

I've been looking at
the Ash Tree Farm evidence

and the killer definitely
doesn't fit the profile in terms of
the Wraith's usual male accomplices.

Why not? The stun-gun, the
handcuffs, the Kevlar boots...

they're all top-of-the-range...
Outside a junkie's remit?

Except that I don't think money
was the real motive here.

All the elaborate props,
the clear, advanced planning,

feels like taking a sledgehammer
to crack the proverbial.

Well I don't know about that.

Mick Francis was ex-SAS,
so you'd want to go prepared.

Ah, Leo, that's it.

Overpowering and robbing an
ex-SAS officer - now that would be

a goal worthy of all that
planning and effort.

You mean it wasn't really about
the cash, it was all about
the trophy - a scalp?

As was raping his daughter.

The police should be trawling
for robberies with similarly
disproportionate and elaborate MOs.

I'd better call Byrne.

Mind if I speak to him first?

He can be tricky and I'd like him
to know this came from me.

Yeah. Of course.

Are you sure you want to know?

Sure. It's a boy.

100%?

110%. Pretty well-endowed, I'd say.

Oh, my God!

Congratulations.

Oh, thank you. Look.

Keep me posted.
The Borough Commander.

Will do. And thanks for coming.

Don't be daft. I'm honoured.

Harry.

I worked on a theft case once
in a bank cash centre.

The thief was clever - he stole
one Ј50 note a day for five years

because he knew the counting
machines had a margin of error

of one note over or under and a tiny
shortfall would be put down to this.

He was patient,
but I was more patient.

We need to test
all the swabs from Chesham Lab

and to hell with the expense.
To hell with the expense.

Leo.

We have an earlier crime that may
have been carried
out by the Ash Tree Farm killer.

Two months ago, a security guard
at an electricity sub-station
was attacked.

He said a young man in
a green Volvo estate pulled up

asking for directions.

Next thing he knew the kid felled
him with a stun gun and robbed him.
Can we match the stun gun burn?

I've requested the file.
Janet says the security guard
is a clear precursor

of Mick's ex-SAS officer status.

Both crimes were challenges...

missions that the thefts prove
he accomplished.

If that's true, then Mick Francis...

Was targeted by someone who knew
he was in the SAS

and who knew he shut up shop
early on a Friday.

A customer seems likely.
Here we go.

Burns on Mick Francis's back.

Burns on the security guard's.

Same burns, same stun gun.

And the model's new, expensive,
and illegal.

And there can't be many in Britain.
Yeah.

The stun gun barbs.

Could they have affected
the security guard's recall?

Only for the ten or so seconds
he was incapacitated. Why?

So there's no way he could've been
mistaken about there only

being one assailant? Unlikely.
Chief!

It's the DVLA.

They've checked Mick's customers...

one green Volvo estate.

Mum?

Mum!

Mum?

Police are on their way.
I'd come with me, if I were you.

I'm your last chance.

Where are you taking me?

Argh!

Is it the model you expected? Yes.

Well, we've two eyewitnesses who
saw Lee going off with

a woman in a hooded top.

Byrne.

Good news?

Maybe. Possible sighting.

Come on! Come on!

Come on!

Ginny!

What the hell are you doing?!

He's seen her face, Guv,
he can tell us who she is!

12 YEARS we've been
waiting for this!

Step away from him!

Please help me, help me!

I don't know what she's talking
about - I don't know any woman!

Please... Don't touch me!

Please! Don't leave me here.

Give me the weapon.

Virginia Gray, I'm arresting
you on suspicion of

causing grievous bodily harm...

Sir, you can't do this!
You can't do this!
You can't do this, sir.

You do not have to say anything,
but it may

harm your defence if you
fail to mention, when questioned...
I did it for you.

Something,
which you later rely on in court.

I did it for you!

Deborah Harding, I'm his brief.
Can you hurry up, please,

we need to take our own
photographs as a matter of urgency.

Hang in there, Lee, we're going to
get you out of here very soon.

Lee, here's how it is.

All the forensics is stacking up.

Your DNA matches blood found inside
the pipe Mick Francis hit you with.

We'll also match your boot prints.
Your knife.

'Your stun gun and the cash
we found in your bedside drawer.'

So, right now, you have one card
left and the sooner you play it,

the better.

You didn't want to hurt anyone,
did you?

You didn't want to rape
that poor woman.

And you certainly didn't want
to kill a child.

'She forced you into it,
didn't she?'

'Made it impossible for you
to say no?'

Who is she, Lee?
Oh, Christ, not again.

What d'you mean "not again"?

The bitch who mashed me up was on
about the same thing. "Who is she?
What does she look like?"

' "How did you meet her?"
I've seen this E-fit before.
The Wraith.

'The woman who shot that copper in
Marlow? That's right.'

It's bullshit
I don't know this woman.

The only woman I know is my mum,

unless you count those
frigid bitches at school and...
Shut up, Lee. Shut up now.

What is the supposed connection
between her and my client?

DNA proves she was there with him
at Ash Tree Farm.

Really? And, er,
where did you find her DNA?

In the pipe.

Sorry - I'm being a bit dim.
So you're saying Mick Francis
hit both of them

'with the same pipe,
causing them both to bleed?

'That's what our evidence tells us.
Or maybe the evidence is telling
you something different'

but you just don't want to hear it.
Such as?

Such as the Wraith
committed these murders

and my client's DNA was planted
after the fact?

Say, by the detective that beat him
to within an inch of his life?

'Such as, DNA means squat if you
can't attach a plausible scenario,

'and you can't.'

The burden's on you to prove
this mentor-protege relationship,

which my client fully denies.

Can you find one person who has ever
seen them together,

'one CCTV image, one e-mail,
one text'

that connects them?

Well, if not, it sounds like a very
large reasonable doubt-shaped hole.

'We'll take a break now.'

I think the brief has this
back-to-front.

Lee's DNA was on that pipe,
no question,
but the Wraith is another matter.

We have to consider
the possibility of contamination.

If Lee carried out the assault
on the substation guard alone,
then why not Ash Tree Farm?

She's the reason he escalated
from a stun gun to rape and murder.

Then why is there no evidence
she was there except the DNA?

Look. I understand you don't want to
consider the possibility
of alternative scenarios.

Alternative scenarios?
Tunnel vision.

It's why you didn't notice that
DI Gray had gone completely
round the bend

until it was too late.

That's a low blow, Nikki.

So is the fact we can't use
the pipe injury on Lee's face

as evidence because DI Gray has
made a total bloody mess of it!

I don't believe for a moment
this is contamination -
not for a second.

If I did, if it was, we'd both lose.

The CPS would rule the pipe
and the blood unsafe

and we couldn't retest because it's
the fruit of a poisoned tree.

Lee Ness will walk if there's any
suggestion the DNA from the pipe
was contaminated. Probably.

So how hard should we
be trying to prove it?

I didn't mean it.

I think you did.

Look, even if it is contamination -
that DNA must belong to some woman.

So?

Well, that has to
be our biggest clue.

How? It's been run against
the national database - no matches.

We have got the Wraith's DNA on
another swab sterilized and bagged
at Chesham Lab. You're kidding!

I think all the swabs that picked up
the Wraith's DNA were
pre-contaminated. How?

But I thought Byrne was guarding
against contamination by using
other labs.

But where did
they get their stocks from?

Look, I'm sorry, Leo, I know that's
woefully inadequate but I really am,
especially after you reached out.

Why didn't you tell Byrne you
supplied swabs to the other labs
he used?

Because I didn't know he was using
other labs until relatively
recently. And when you did?

Well, I suppose
I didn't think it mattered.

You'll have to explain that.

Look, he was worried
about contamination, I wasn't.

I never doubted this woman existed
or that it was her DNA

we were detecting.

Who else has worked consistently
at Chesham labs since 2000,

apart from yourself and Lizzie?
Nobody.

But Lizzie is a pathologist.
If the contamination's accidental -
a handling issue or mishandling...

If she was responsible it would have
to be deliberate?

Yes. Which is unthinkable.

But you've thought about it?

Only since her suicide. Why?

I don't think we need to explore
this avenue any further.
I think we do, Leo.

Look, I loved Mary, Lizzie's sister,
and I believe she was in love
with me.

But the person she loved most in
all the world was her big sister,

and vice-versa.

And? I fully expected her to lead
the charge in blaming the police
for their role in Mary's murder.

But she didn't?

No. That fell to me.
Lizzie, well, appeared to forgive...

if not forget.

Well, that was her nature.

Yes.

But you're saying that in fact,
she never forgave the police
but created the Wraith

to send them
on a 12-year wild goose chase?!

Look, Leo's right - this isn't
something we need to explore

because Lizzie's DNA
doesn't even match.

That doesn't prove anything.

She was a pathologist, she could've
used any Jane Doe's DNA to
contaminate those swabs, she could.

What happened to Mary's killer?

He died in prison before the case
even came to court.

How?

Drug-related heart failure, I think.
You'd have to ask Byrne.

What's Byrne got to do with it?

Well he was, he was the ranking
detective at the scene
when Mary died.

What? You didn't know that?

Hello, Nikki.

'What does the name
Mary Fraser mean to you?'

Mary Fraser's murder was a tragedy,

what could it possibly have to do
with this inquiry?

I'm not sure, but within months of
her death you found the Wraith's DNA
at the Stiles murder.

Coincidence. I don't think so.

I don't think her DNA was even there.

The swab that detected it was
already contaminated.

What about the control swabs?

This wasn't an accident,
this was sabotage.

Come on Nikki!
When we absorbed Chesham's work
they offered us their stocks.

Out of 2,000 swabs, we've
found the Wraith's DNA on five.

Never on the control swab,
never more than one per batch.

No, no, it's not possible.

I'm sorry. I know what you've
given to this case.
No, you really don't

But Meg Stiles,
Ray Carpenter, PC Amar,

all these cases are unrelated crimes
carried out by different people.

We found a syringe of her blood
at the Stiles house.

We sent that blood to at least two
other labs, not just Chesham.

Chesham supplied those labs
with swabs.

Is it possible that the syringe
was planted at the scene?

Anything's possible

But was there anything
unusual about its discovery?

We didn't find it
until the following morning.

Who was the pathologist
that attended? Bear with me.

Professor Lizzie Fraser.

'My sister Mary was murdered
by a crack addict

'at a crime scene the police were
supposed to have secured.

'Now, I did not sue for dismissals,

'I did not seek to apportion blame

'and I urged my colleagues

'in the Forensic Science Service to
pull together with the police to
ensure her killer was convicted.'

What about Simon Avery?
He used to be a forensic scientist.
Did he attend?

No. Avery never worked in the field
after Mary was killed.

Too traumatised.

Besides there were question marks
over his conduct the day.

His conduct?
I thought it was all your fault?

Well we weren't exactly
blameless either.

OK. We've got a deceased, as yet
unidentified female through there.

Looks like she's been
stabbed to death.

Now we've secured this floor
but not the next,

so confine your work
to down here only.

'We hadn't cleared the upstairs.'

That was our fault - the whole
building should have been cleared.

'But Avery had
years of experience in the field...

'he should've known better.'

Mary!

Mary! No! Mary!

YELLS: Mary!

If he knows that it was
more his fault than yours,

then taking revenge on you
is his way of re-writing history.

Simon? Simon Avery? No.

Could he have planted that syringe
overnight at Meg Stiles' house?

Theoretically - scientists
from his lab processed the scene.

Who was the murdered woman
in the crack house?

We never identified her.
Was she an addict?

Aye, riddled with it. Why?

The blood you found at the Stiles
scene tested positive for crack

and heroin, didn't it? What else
did you find out about this woman?

Some of the drug addicts
said she was Canadian,

'but she had a tattoo
of Australia on her arm so...'

Well, either makes sense.

Not to me it doesn't...

The Wraith's DNA never even
scored a partial match
against the UK database...

not a parent, not a sibling,
not a cousin.

Hold on, Nikki.

We found one of her hairs
in the Amar car two years ago.

At the scene or at the lab?

At the lab, but the follicle was
complete, we got DNA from it!

Well, then he's preserved her body
and he is keeping it close by.

The body of the Jane Doe
was lost in transit

between Chesham Lab
and the crematorium.

I don't know. She didn't have
many friends or family so there
wasn't much of a fuss,

I suppose, but the paperwork

'releasing the body
to the crematorium was signed by
Simon Avery.'

And what about the DNA?

I don't know. He must have removed
it from the database somehow.

You can rest easy about Lizzie.

Thanks, Harry.

Simon Avery, we have a warrant to
search your property.

Enter. The scene's secure.

No knife-wielding crackheads
on the premises.

Avery!

Stop! Stop!

No, stop!
That's exactly what he wants!

The subject - a still unidentified
female - has been dead

for a number of years but the body
has been preserved in a freezer.

The body has sustained significant
injuries post-mortem.

Quantities of flesh, and hair
and, apparently, blood

have been removed and stored frozen
it seems in a variety
of vials and syringes.

There are some signs of early
stage decomposition...

which would suggest the body
has been thawed and re-frozen

at least once, perhaps for
extraction of further blood
and tissue samples.

There is extensive evidence
of long-term intravenous drug use

and severe trauma to the chest
consistent with stabbing...

both of which...

both of which were comprehensively
documented at the original
postmortem in 2000.

Small quantities of Hydroquinone
were found at Avery's house.

That's the chemical that appeared
then disappeared in the mosque
bomber case.

Sorry, so what are you saying?
That he set Lizzie up?

Did he bear any
kind of grudge against Lizzie?

No, I don't think so. I mean
they worked together for years.

What about before Mary's death?

What did Lizzie make of him then?

You mean, did she approve?

Mm?

Well she thought that Mary
could do better.

And did she tell her that?

Come on,
you know what big sisters are like.

Might she have tried to talk her
out of the relationship?

Probably. I don't know.
Does this really matter now?!

It may have mattered to Avery.

What was it you said?
"There's no comparison."

You may have been wrong there.

What is it you are so scared of
Shannon? He's going to find me.

Make sure she knows I'm worried.
Shannon Kelly is 15 years old,

and we suspect she was sexually
abused. The death last night,
body collapsed in the street.

He wouldn't have felt ill
until he died where he dropped

DI Vickers. I need Professor Dalton
to attend a crime scene now.

In a suitcase?
She could be from anywhere.
