All language subtitles for Silent Witness - 24x06 - Reputations, Part 2.AMZN.NTb.English.C.updated.Addic7ed.com

Victim is Mr Arnie Rahul.
Consultant surgeon. 48 years of age.

Good reputation, though he's fallen
out with a few people recently.

He was about to start an operation.
He gets a phone call.

Walks out, never comes back.

Single puncture wound to
the left chest wall.

- What's that in his hand?
- Looks like a syringe and needle.

It's a Hickman line.
A long-term vascular access device

for people who need chemotherapy
or blood transfusions.

The assailant would have had
extensive cross contamination

with the victim's blood.

Stick that in to a big artery
and blood will flow out

like a high-pressure hose.

Simi Jacobs.

He's denying everything.

Simi Jacobs is not a match

to the blood spatter at the scene.

So, who is it? It's Wilfred Okoye.

The patient?

Arnie Rahul was murdered by a man
who was under general anaesthetic

in a different room?

Blood alcohol level, three times
the legal driving limit.

You said he shouldn't be operating.

Not after the Harry Fletcher incident.

Arrested on the table
during surgery last week.

I want you to do the postmortem.

Technically that would be
a conflict of interest.

Summarising postmortem examination,
Harry Fletcher.

What are you doing?
My colleagues are here.

- Is that Emily Braithwaite?
- She's Adam's godmother.

You'd think he might have
mentioned it.

- Are you going to confront him?
- Not yet.

Your original stem cell work
was brilliant.

But you tried and failed to turn
it into a viable cancer treatment.

Wilfred Okoye, still in the hospital.

What's he going to know?

You won't find out unless you ask him.

Mr Fletcher died because of
surgical error.

Adam! You have no idea what
you've done.

When I applied for this job
I falsified my CV,

and Emily Braithwaite tried to
use this

fact to influence my findings in
the Fletcher Case.

Here's my letter of resignation.

Effective immediately.

Wilfred Okoye, a Beninese
farm worker, was admitted

to St Jude's hospital for the
treatment of leukaemia a week ago.

Although he lost consciousness
briefly during the attack

on his life last night, he seems to
have recovered with no ill effects.

Awaiting toxicology from the syringe
we believe was used in the attack.

Prints? Fibres?

- Nothing conclusive.
- We're interviewing witnesses

but no-one got a good look at
the attacker.

How come he's being treated here
in the UK?

It was set up by a charity,
and then arranged through Rahul.

Here is a man who has lived his
entire life in Benin

up until a week ago, and,
according to our DNA evidence,

murders his surgeon while under
anaesthetic in a different room.

Could the DNA at the murder scene
been a contaminant or planted?

No. The spatter patterns are
too perfect.

It came from someone who
was in the room at the time.

So, how do you explain it?

How do we know Wilfred
was anaesthetised?

I mean, how do we know it was him?

What, he's got an identical twin?

Bit fantastical, Steve.

I don't know.

There's another explanation.

DNA samples got mixed up.

Ah! No way!

Look, I'm just putting it out there.

- Mm-mn.
- We could run the test again.

Those samples were handled correctly.

Jack, shall we just run them again?

Right, yep. Good.

OK.

Let me know when toxicology
comes back.

So, the samples got mixed up,

- did they?
- It's always possible.

Mm-hm.

You know who took the swab from
Simi Jacobs. Adam.

What are you suggesting?

Just saying.

You have reached Dr Adam Yuen.

I am unable to take your call.

Please leave a message after the tone.

Do you know what I don't understand?

It was just a six-month placement,

and his CV is impressive
enough without it.

So, why did he risk his career
and lie about it?

Has he lied about anything else?

Everything else checks out.

Are you sure about that?

You have an injury over your
left eye and a wound on your neck.

How do you account for them, Simi?

Yeah, I got mugged.

- A kid with a knife.
- Really?

And did you report the assault?

- No.
- Why not?

What, are you going to catch him?

He's answered your questions,
so unless you have other evidence?

Tox results from the syringe
used in the attack on Wilfred.

- Here we go.
- Let's have a look.

- That's it?
- Midazolam?

That's a sedative, isn't it?

Yeah.

The full syringe would have had
about five milligrams in it.

That's not very much.

So, either the assailant
is incompetent,

or this wasn't intended to kill him.

So, what's the aim?

Kidnapping?

The guy's already ill.

You know...

If someone wanted him dead, it's not
going to be that hard, is it?

He's got leukaemia.

It would look like natural causes
if he died of sepsis.

Should I get that syringe tested
again for bacteria?

What's this about Mr Okoye
being moved?

It's for his own safety.

To the Cowley Institute?
And who's paying for that?

Oh, I've been assured that they have
all the facilities required,

and they've offered to do
the treatment free of charge.

I will not allow it.

Someone in your hospital is trying
to kill Mr Okoye.

Quite frankly, Dr Braithwaite,
I don't need your permission.

Haematology lab.

Dr Braithwaite here.

Wilfred Okoye, hospital number
1187266.

I want all his stored blood
and marrow samples sent

to my office immediately.

Finished!

79 needles swabbed and ready to go.

You've got to see this.

Microbiology results from the syringe

used in the attack on Wilfred.

Turns out it is full of bacteria -
E coli.

Well, it was lying around on
the floor.

Could it be a contaminant?

No. It's a pure growth -
just one type of bug in there.

If it was a contaminant
you'd expect to see

lots of different organisms.

It's been created deliberately.

So, what? The killer sneaks into
Wilfred's room pretending

to be a nurse, inoculates him with
the bacteria,

but adds a mild sedative...

..so that when the real nurse comes
in with his medication,

he's asleep and can't tell her that
someone else has already been in.

He gets sepsis, he dies.

Looks like natural causes.

I need to tell DI Cracknell.

You need to tell the doctors
looking after Wilfred.

It's as we expected - extensive
peripheral oedema,

multiple organ failure,
consistent with sepsis.

Yep. Toxicology shows only
medications used for his treatment,

antibiotics, ceftriaxone,
gentamicin present

in therapeutic concentrations.

So, cause of death is consistent
with deliberate inoculation

of the culture of E coli,
on a background

of chemotherapy-induced
immune compromise.

Well, we've got no other
leads on his attacker at present.

We're liaising with
the Beninese Consulate to inform

the family of the deceased.

DNA says Wilfred Okoye was guilty of
Rahul's murder,

but being unconscious,
had the perfect alibi.

When a murder suspect gets murdered,
what does that mean?

Framed by the real murderer?

Why would you frame someone with
the perfect alibi?

Simi Jacobs.

What's his home address?

Erm...

Let's see. Flat 32, Bardwell House,
Lincoln Street.

Thought so. Okoye and Jacobs have
been living together.

Simi Jacobs has already been
released, guv.

- What?
- Yeah. Lack of forensics.

All right.

Might I suggest we pick him up again?

It still doesn't get us anywhere.

It doesn't explain the DNA.

And Simi was in custody
when Wilfred was attacked,

so it doesn't even explain that.

- We're just going round in circles.
- Yep.

When he was interviewed,
Wilfred said his leukaemia

was common in his region.

Doesn't sound right to me.

You have reached Dr Adam Yuen.

I am unable to take your call.

Please leave a message after the tone.

Wait there. He's not in, guv.

And the neighbours haven't seen him.

He's not been seen back at work
at the hospital either.

You two stick around in case
he comes back.

I'm sorry, guv. I should
have spotted the address.

Don't worry about it.

At least you didn't wrongly arrest
a bereaved cancer patient.

I'll do that next time.

Bye.

Nine missed calls.
You're very persistent.

I didn't want to end it like that.

Can I help?

You should have told me that
Emily Braithwaite is your godmother.

Some godmother.

No doubt you've received
the incriminating evidence about me.

What evidence?

She never sent it.
I should have guessed.

If she tried to blackmail you,
then we'll make her answer for that.

She's far too clever.

Why do I think there's more to this
than you're telling me?

No, I just lied to advance my career.

Really? Just to say you had a
fellowship. Why would you do that?

My family are all doctors.

I was always going to be a surgeon.

It was more or less decided for me.

Final year of medical school,
I was walking to uni

and a cyclist is knocked off her
bike, right in front of me.

Now, I was a keen student.

I used to carry
a first aid kit around with me.

If I'm honest, I was always waiting
for something like this.

When I think about that it's
actually what I'm most ashamed of.

She had facial injuries.

Heavy, laboured breathing.
She was losing consciousness fast.

So, I thought, "She's suffocating.

"She needs a surgical airway,
a cricothyroidotomy."

So, I made my incision.

Something that I had
practised on mannequins.

What I didn't know is that she had
an abnormal anatomy -

an aberrant subclavian artery,
looping high in the neck.

It's present in 1% of people
and 0% of mannequins.

- How could you have known?
- It was a bloodbath.

The artery retracted back into
her chest.

There was nothing we could do
to save her.

She bled to death in minutes.

My father was furious.

Not because I stupidly tried
a tracheostomy

and killed an innocent young girl.

But because I didn't study hard
enough to do it competently.

So, he used his influence
and arranged for my fellowship

- as cover.
- For what?

For my absence.

It took months of therapy before
I could even leave the house.

The irony in all of this is that
the one who helped me out

the most was Emily Braithwaite.

She visited me more often than
my parents.

She understood.

But there was no way I was going
to be a surgeon.

So, I decided to choose pathology,

and a false narrative was created as
to why I made the switch.

When you start lying,

you have to keep lying.

Jack.

- Mm?
- I need to talk to you.

Sure, what's up...?

Hi.

Are you kidding me?

He doesn't work here any more
because he lied to us, do you

- remember? Do you remember that?
- Adam's got a theory about Wilfred.

- Oh, right.
- Just hear him out.

So, um, I just have to trust him now?

No, you've got to trust me.

Think about it.

Why would someone want Wilfred dead?

What did he know that was such
a threat that someone

had to kill him?

Wilfred was being treated for acute
myeloid leukaemia.

That's rare.

Remember, he said there were
lots of other cases in his small

village in Africa.

What if Wilfred wasn't killed
because of what he knew?

Don't follow.

Wilfred wasn't the witness.

He was the evidence.

This is a trephine biopsy of
the bone marrow.

We take a thin core of bone
with marrow cells in it.

I've already taken an aspirate of
the fluids.

So, the question is, why would so
many people from one place

all get leukaemia?

And that's going to tell you, is it?

To be honest, I've never done
this before.

Not postmortem, anyway.

But you know what? It's crazy
enough for it to work.

Mm-mm.

Thanks.

Oh, look. Here's a billion
DNA results from the needles.

Want to give me a hand going
through these?

Didn't think so.

Nikki? The slide's ready when you
want to have a look.

Good yield of cells.
More than I expected.

Definitely acute myeloid leukaemia.

It's not typical.
Looks more like secondary AML.

- Secondary to what?
- A toxin of some sort.

Some industrial chemical, for example,

or chemotherapy for
a different cancer.

Right. And that can occur years
after the original exposure.

Decades, in some cases.

So, there may be other victims,
all exposed to the same thing?

Makes sense.

Can I help you?

They told me Wilfred is here.

Can I see him, yeah?

- Er, you are?
- Family.

Do you want to take a seat?

Will I be able to sit with him
for a bit or...?

I'll just check.

I've found Rahul's murder weapon.

One DNA profile matching Rahul,
one matching Wilfred,

just like we found at the scene.

But there's a third profile.

Yep. Simi Jacobs.

Simi? He's here!

What do you mean he's here?
He wants to see Wilfred's body.

This places Simi at the scene
of Rahul's murder.

We need to keep him here.

Call DI Cracknell.

So, hang on.

Simi Jacobs just turned up at the lab.

One needle injected into three people.

Better get down here.

Simi had a puncture wound to his neck.

Rahul was stabbed in the chest,
but Wilfred?

And if Simi got in a fight with Rahul,

why is Wilfred's blood spattered?

Wilfred would have to have
been in the room as well.

Maybe he was. Genetically speaking.

What if that needle only stabbed
two people?

Then one of them has two different
types of DNA.

Exactly.

Huh? No, for that to work, it would

mean Simi's walking around with
Wilfred's blood inside him.

- That's ridiculous.
- Is it?

- Bone marrow transplant.
- And Wilfred was the donor.

So, Simi's blood has Wilfred's DNA.

Do you want to come this way? Yeah.

Just there.

Can I get you a tea?
A glass of water or...?

Oh, no, no!

Thanks.

You said that Wilfred was family?

That's right.

Was he a close relative?

You ask a lot of questions.

Remember me?

I examined you at the station.

I saw a scar on your chest.

That's a Hickman line scar.

Did you have a bone marrow
transplant as a kid?

Yeah, I'm going to go.

Simi, we found your blood at
the scene of Rahul's murder.

Did you kill him?

No, no, no. He... He came at me!
He was insane!

It was an accident!

I just wanted to protect Wilfred.

Wilfred saved my life
when I was a kid.

But you know what? He could only do
that because he was a match.

People have transplants from their
brothers or mothers or whatever

because they're a match. I had no-one.

How did you find him?

There's this charity
attached to our church.

They helped us get
the transplant records.

Only it turns out Wilfred was sick.

- Were there others?
- Yeah.

I mean, loads of people in his
village died from the same thing.

We found Wilfred in time.

So we thought.

What?

You're not going to let me see him?

Simi.

There he is.

Ah, afternoon! Present from
DI Cracknell -

all the rubbish from
Simi Jacobs' address.

Thought you might want to take a look

in case you find anything relevant.

Joy.

Can I introduce Reverend Kanu?
You've already met Jack.

This is Dr Nikki Alexander...

- Hello.
- And Dr Adam Yuen.

Reverend Kanu runs the charitable
organisation that was responsible

for bringing Wilfred to the UK.

I have some photos from our trip.

Sergeant Galloway thinks
they might help you.

Thank you.

I have to warn you,
they're not pretty.

Tell me how Mr Okoye came to be here.

My church runs a charity that helps
arrange treatment in the UK.

They raise money, get doctors to
volunteer, whatever.

Wilfred's case was kind of special.

I mean, he helped me years ago,
and now he needed my help.

The local newspaper picked up
the story,

it got a lot of publicity.

So, the hospital agreed to treat him.

- And he stayed at your flat?
- Yeah.

Nobody told me he don't speak English.

I couldn't tell him anything.

He didn't know who I was,
what he did for me.

Then I learnt that he's under
the care of this Rahul guy.

I have travelled widely in Africa
as part of my ministry,

and yet nothing could have prepared
me for what we found in Bwendora.

The town is remote, even by
African standards.

There is only very basic health care.

It became clear there was a
lot of sickness.

This man died within hours of
our arrival.

The illness causes bleeding
and rashes. Fever sometimes.

What do the people think it's
caused by?

There's a large pesticide factory
in the town.

Many people think the water has
been contaminated.

They organised protests.

People think there has been
a cover-up.

But the factory provides
a lot of employment.

It is a very divisive issue.

The illness has ripped the heart
out of the community.

There are very few families it has
left untouched.

And they've had no outside help?

There is one western charity
which runs a clinic,

but they only visit every few months.

Some charity.

Oh, Lord.

Enlighten our minds with your truth.

Give us the strength and the wisdom
to seek justice.

Shine your everlasting light into
our darkness.

There's a lot of talk about Rahul,
all around the hospital.

How the hospital is protecting him.

How he messed up an operation
and no-one wants to work with him.

And you thought he shouldn't operate
on Wilfred.

The night before, I heard him
arguing with this woman,

Dr Braithwaite.

She told Rahul not to do the operation

and he just told her that
she couldn't stop him.

The bag of rubbish that we
found at your home address.

Was it from one of the offices?

- Yeah.
- Which one?

All of them.

I was looking for something, anything,

I could use against Rahul.

And on the morning of the operation?

I saw Wilfred getting prepared for
theatre and I panicked.

I phoned Rahul.

What did you say?

I told him I had some information
on him.

I thought I could threaten to reveal
what I knew if he did the operation.

What information?

I was bluffing. But I had to stop him.

Well, you certainly managed that.

How's it going?

Oh, I'm in my element rummaging
through the trash. You know me.

Nothing much here, apart from
a criminally lax attitude

to recycling.

Adam's still here, is he?

We wouldn't have got this far
without him.

I want to trust him.

What's that?

Oh, my God.

This was in that rubbish bag you
found at Simi Jacobs' place.

It's Harry Fletcher's ECG,
taken the day of his operation.

It's normal.

And this is the ECG that
appeared in Fletcher's notes.

Same date and time,
but grossly abnormal.

We believe they were switched
to deflect blame from Rahul

after the operation went wrong.

So, there was a cover-up?

Well, what's this got to do with
the murder investigation?

Yeah, Simi Jacobs admitted to
the attack on Arnie Rahul.

I mean, he claims it was an accident
as a result of self-defence.

That fits with the
crime scene findings.

So, how does this transplant fit in?

Well, Simi was born with
sickle cell disease,

and was treated with a bone marrow
transplant at St Jude's as a child.

Wilfred donated his stem cells
for Simi's transplant.

20 years later,
Wilfred gets leukaemia.

We don't think this is a coincidence.

He had a type of leukaemia
that can be caused by over-exposure

to certain drugs.

There's a technique known as
mobilisation,

which is designed to increase
production of stem cells.

Normally, stem cell donation
involves giving a perfectly safe

bone marrow stimulant.

But whoever did this also gave
Wilfred high levels of chemotherapy,

and did so repeatedly.

They gave chemo? To a volunteer?

To yield even more stem cells.

What for? More transplants?

Stem cells have the ability to
develop into any type of body cell.

Brain, heart, blood - you name it.

So there's a huge range
of potential therapies

in which they can be used,
one of which is transplantation.

About ten years ago, Braithwaite
and her team identified stem cells

that were very special indeed,

capable of being turned into
what are called killer T-cells,

part of the immune system, which can
be made to attack malignant tumours.

The potential for this discovery
was enormous.

These magic cells
all had the same gene,

a gene we think might be common
in Wilfred's town.

They went looking for transplant
donors to treat people like Simi,

but what they discovered
was something much bigger,

so they went back for more, and more.

Basically they were flogging him
for every last stem cell

- he could produce.
- Him and all the others.

Wilfred's town was basically
a stem cell farm.

Can you prove Wilfred
was given the stimulating drugs?

It may be possible,
but that's way out of my league.

Sounds like we need a second opinion.

Thank you, Professor.

Not at all. It's very good to see you.

- Thank you.
- Oh, he's away!

- Adam, hello again.
- Hello. This is Dr Nikki Alexander.

- Hello.
- How do you do?

And you've already met DI Cracknell.

Yes, of course. This way.

That was Alfie.

He's one of our early trial patients
osteosarcoma.

When he was referred to us,
he was in a hospice

on palliative treatment,
expected to die within weeks.

Please. That was two years ago.

He's now disease-free.

We wanted to show you some
bone marrow samples from Mr Okoye.

He was moved from St Jude's
to be treated here.

Hmm.

Secondary leukaemia.

They look very unusual.

Mr Okoye was a stem cell donor.

Was he?

We were wondering
if it might be stimulated.

You mean Cyclo-G?

Oh, dear.

Yes, it's possible.

Is there any way we can confirm it?

You would need to look into
the genetics of his blood cells.

There are some telltale signs.

We have several world experts
in cytogenetics here.

They'd be happy to help.

Your cancer therapies are based
on Braithwaite's stem cell research,

- are they not?
- Yes. Yes. I've never denied it.

Hers was an extraordinary
piece of work.

She tried for years to turn it into
a practical treatment,

but, in the end, she was stumped
by the obvious problem.

The limited supply of donors.

Precisely.

So, what we brought to the party
is called gene editing.

We found a way of inserting
the special gene

into any old stem cell,
and the result is...

Well, you met Alfie.

What is your relationship
to Emily Braithwaite?

Yes.

Well, I suppose you'd say
we're rivals.

She's never forgiven me
for succeeding where she failed.

But I'm afraid her star
has been waning for some time.

What makes you say that?

She came to ask for my help.

Believe me,
that alone suggests desperation.

She had just lost a very large
research grant.

Is it possible that Braithwaite
poisoned Mr Okoye

and everyone else in his town
to get more stem cells?

That's a serious accusation.

Everything's falling apart.

So, like a gambler,
she risks more and more,

desperate for that big win
to get herself back on top.

- Now what?
- Excuse me?

- You do realise my career is over?
- And that's my fault?

There's got to be a way out of this.

You owe me that at least.

You want Auntie Emily
to make it better?

All those years I stuck up for you
with your father.

You messed up. Again.

For once in your life, own it.

I don't get it.

You and Rahul.

You go to all these lengths
to protect his reputation,

yet you show no interest
in who might have killed him.

You don't even seem to even care
that he's dead!

Maybe I've learnt to bury my emotions.

You should try it.

You know they're onto you,

and I'm not going to help you
this time.

Oh, please.

This is so painful.

So, all roads lead to Braithwaite.

Yes, but it's all circumstantial.

There's nothing directly
connecting her to Wilfred.

If you can find me something
concrete, I'll bring her in,

but until then, it's just speculation.

Adam, where did you get to?

Rahul's conduct during
Fletcher's operation amounted to

criminal negligence.

He could have been charged
for manslaughter.

Well, he's dead.

What if Braithwaite covered it up?

That's attempting to pervert
the course of justice.

Which means you can arrest her.

Oh, and how do we know that
Braithwaite swaps the ECG?

We can't. There are several
sets of prints on the trace,

one of which could be Braithwaite's.

Exactly, so we can't just arrest her
on the off-chance that

- her prints are on there.
- I know.

I met her for a drink.

Her prints are on this glass.

When you find that they are
the same as the sets on the ECG,

- then you can arrest her.
- That's not admissible as evidence!

It doesn't have to be.

How do we know for sure
she touched this glass?

Well, you're just going to
have to trust me.

You two go round the back.

Her car's here. Looks like she's home.

No letterbox.

Dr Braithwaite?

DS Galloway.
Could you open the door, please?

- Police!
- Dr Braithwaite?

Shit.

No sign of external injury.

Both front and back doors
were locked from the inside.

There's no signs of forced entry.

Everything's neat and tidy.

Sudden chest pain, maybe?

Or suicide.

Nikki. Adam. Look at these.

Two samples
with Wilfred Okoye's name on.

Look at this.

The boiler's locked out.

Yeah. Mine does that all the time.

Bloody things.

Heart weighs 380g.

Evidence of left ventricular
hypertrophy.

Valves unremarkable.

Left anterior descending
coronary artery.

Moderate stenosis,
no evidence of thrombus.

The toxicology was entirely negative,

apart from a modest level of alcohol.

No paracetamol,
no benzodiazepines, nothing.

So this, together with the absence
of pills and containers

at the address, and the absence
of any needle marks on the body,

leads me to conclude that death
was not as a result

of suicide or poisoning.

In fact, the only significant
finding from the postmortem

examination is moderate ischaemic
heart disease,

together with hypertrophy of the
septum and left ventricular wall.

But no evidence of
coronary thrombosis?

The ventricular wall thickness...

- Heart attack.
- ..and the degree

of myocardial disarray on microscopy
are borderline

for a diagnosis of HCM.

- What's that?
- Hypertrophic cardiomyopathy.

It's an inherited heart condition
that can lead to sudden death.

- Fabrice Muamba.
- Yes.

Bolton Wanderers versus Tottenham.
FA Cup quarterfinal, 2012.

He collapsed on the pitch.
Nearly died.

Well, technically he did.

In cases of high stress or exercise,

the heart can lead into an abnormal
rhythm, which can be fatal.

And Emily Braithwaite
was under a lot of stress.

So it is possible that this caused
a dysrhythmic event...

- Heart attack.
- Heart attack.

..that led to her death,
don't you think?

How come she didn't have a letterbox?

It's a passive house.
It's so well-insulated,

it doesn't need heating.
You heat it up just by living in it.

But it has to be really airtight.

It's like living in a bubble.

All the air goes in and out through
a single ventilation system.

But why would the boiler lock out?

What if it was faulty and produced
a lot of carbon monoxide?

No carbon monoxide in the toxicology.

She's a suspect in a murder case.
She conveniently dies.

What if others were involved?

If you can tell me how they did it,
I'll believe you,

but until then,
it's looking like natural causes.

Right, then, provisional assumption
is that Braithwaite

was guilty of conspiracy
to murder Wilfred Okoye,

as well as perverting the course
of justice in the Fletcher case.

What about Simi?

That's up to the CPS, whether
they buy a self-defence plea.

I'll keep you posted.

So this is where you've been hiding.

Adam told you, then?

Oh, yeah. He told me everything.

I don't get it.

How could someone like Braithwaite
justify it to herself,

let alone anyone else?

They get fixated on the prize,
don't they?

The breakthrough, and all
the acclaim that goes with it.

Mm.

Did you ever want to do something
like that? Fancy research job?

I think you'd be really good at that.

I don't know.

- It's more Adam's world.
- Mm.

Not any more.

You can see how liberated he's been.

He's carried that secret around
for so long.

Well, he's stopped trying to
be all things to all men.

And I'll tell you,
he loves beating himself up.

Hi. I'm working on the case
of Wilfred Okoye.

I was wondering if I could get
his microbiology results

from his stay here.

Date of birth is 9/7/66.

I just need to, er,
speak to my supervisor.

OK. Thank you.

It's Adam.

"We were wrong about everything.

- "At Cowley Institute. Come quickly."
- What?

What are we looking at?

Wilfred's blood cultures.
Microbiology report.

Hang on.

The antibiotic sensitivities
have been reversed.

Who's done that? Braithwaite?

Couldn't be. These are from
the Cowley institute.

Adam needs us. Come on.

Oh, great. We were supposed to
go left back at the lights.

Dr Yuen?

You know Emily Braithwaite
died yesterday?

What? Uh, no. How did it happen?

Unknown. Found dead in a house
that was bolted from the inside.

Oh, look, an oxygen analyser.

Do you always keep one of those
in your car?

I use it for various things.

So Emily died just as
you convinced us she was guilty.

Her work was based on exploitation.

Well, she can't deny that now,
can she?

Well, whatever happened,

I'm sure forensic science
will find the answer.

Mm. Then I realised just how much
liquid nitrogen you go through here.

Two deliveries in three days?

I mean,
that is some evil genius stuff.

Pretty quick and very clean.

Except the pilot light in the boiler
went out at Braithwaite's house.

Otherwise, the perfect crime.

Are you insane?

- Oh, sorry. That's forensic science.
- Get out.

Braithwaite had Wilfred's
blood samples. She was onto you.

My research is changing lives.

She never made the crucial
breakthrough,

but then again, neither did you.

You reckon you'll crack it
any minute now, don't you?

You just have to keep going,
keep blasting innocent men

and women with poisonous drugs,
and then you'll get there.

- You know nothing.
- There's no gene editing going on here.

Your magic treatments are all
from stem cells that you get

from killing people like Wilfred.

When childhood cancer is
a thing of the past thanks to me,

no-one will care.

That's what it's all about, isn't it?

It's not about the money or the power.

It's about the prestige.

So what are you going to do
about it, Adam?

Mm? You're discredited.

You're getting struck off.

Of course I know!

I know everything.

You've no idea
who you're dealing with.

Adam?

Adam!

Adam? What's happening?

Cowley's the one exploiting Wilfred
and the rest of the donors.

And he killed Braithwaite
with liquid nitrogen.

He poured it in the vent
of her airtight house,

turning it into a gas chamber.
She suffocated.

Cowley did a deal with Rahul
to kill Wilfred during surgery.

And when that failed, he attacked
Wilfred with the bacteria...

..to make sure he switched
the micro reports

so that the antibiotics wouldn't work.

Adam?

Adam!

- I'm sure that's Cowley.
- Really? Call Cracknell.

- But...
- Get after him. I'll find Adam.

Yeah, I'm heading north
on Colbridge Road.

It's a black Mercedes.

Adam?

Adam!

Oh, Jesus.

Ambulance.

Can you hear me? Adam?

You took your time, mate.

Come to take all the credit?

Oh, man.

The ambulance is on its way.
What happened?

I messed up.

You trusted me.

That means a lot.

Adam. Adam, stay with me.

Adam. Come on, man. Stay with me.
Stay with me.

Come on! Adam!

Adam!

Oh, God.

Oh, no.
