(READS) 'I may not even answer
at my trial

and it seems to me that there is
so much of this strength in me now

that I shall vanquish everything,
all of the suffering,

only so that I may keep saying to
myself constantly, "I am!"

I may endure a thousand torments,
yet I am.

I may writhe under torture,
but I am.'

I may sit in a tower, but I exist.

I can see the sun,

but even if I cannot see the sun,
I know that it exists.

And to know that the sun is there...

..that is living.

15.

It must be my lucky night.

My eyes are tired.

Maybe I should get an audio book.
They don't complain.

They don't get your medication
either.

Or post your letters.
Or see that you do your exercises.

You do bang on, don't you?

Thanks for the lift.
It's not like it's out of my way.

Still, it's a bit early for you
to go in, isn't it?

I like to pull my weight
now and then.

This is how the last one began.

Call me, will you? I left early
this morning. You were still asleep.

Just let me know you're OK.
Frank!

Pick-up in Wantage.
Again?

Ladies.

Morning. Any mail for me?
Yes, Professor Capstone.

That's great.
There you are.

You've had your hair done?
Yes.

Very chic.
Thank you!

Bomb disposal have given us
the all clear.

Major blast trauma
to the head and torso.

Severe lacerations
from the shrapnel.

Designed to kill, then,
not just maim.

Adam Capstone. 34.

Currently Bridson-Whitereid
Professor of Geometric Topology.

Pure maths, rather than applied. And
not to be confused with topography.

As if.

The secretary confirmed the parcel
arrived in the post this morning.

Find out next of kin and get
Family Liaison on to them. OK.

See if anyone was seen hanging
around prior to the explosion.

Whoever did this might have stayed
to admire their handiwork. Sir.

Excuse me. You have to let me -

Detective Inspector Lewis.
Can I help?

I work here.
They said there was an accident.

Would you like to move back, Mr...?

Capstone. David Capstone.

Are you related to Adam Capstone?

He's my brother.

Would you like to come with me, sir?

How long have you and your brother
worked here?

Erm...we never really left.

I got my double first at 17.

Stayed on to do an MSc.

And then I joined the staff.

Adam was the same.

Only he got his double first at 16.

Two geniuses in one family.

That's an over-used word but erm...

We specialise in knot theory.

Knots have their own theory?

Yeah, there's some of them.

But it's the ones in DNA that
we're particularly interested in.

If the human nucleus
was the size of a basketball,

do you know how long the DNA
inside would be?

150 miles.

Sorry.
It's what Adam tells his students.

Erm...TOLD his students.

Er...for the last few years,
we've erm...

If you can figure out
how DNA coils up, how it's packed,

then you can unpack it.

Modify it. Repair it.
That's what we've been trying to do.

A team.

Any idea who would want to attack
you like this?

Er...our research?
If what we've discovered is correct,

then we're talking about new ways
to fight genetic diseases. Cancer.

New hope. New life.

Why would anyone want to stop that?

Maybe it was more personal.

Erm...

..these came.

Adam wanted to get rid of them.
Said it was a crank.

That if we ignored them,
they'd go away.

Any idea who sent them?

Mr Capstone?

Erm...

Well, there's someone.
But I-I can't believe that she'd...

Kate McMurdoch.

And she is?

She was one of our students.

Got it in her head that she'd made
some major discovery.

Accused us of stealing her research.

And had you?
No. God, no.

It's an inflated sense of her own
importance, I'm afraid.

We had to let her go and...

she wasn't happy.

Open day at the allotments.
Said I'd help on the cake stall.

You haven't got time.
I'll make time.

And the hospice? The day centre?

Checking up on me?

Find out if any groups have got it
in for this kind of research.

Yeah, James is doing that -
Individuals too. Blogs.

Videos where they rant in their
bedrooms. Sir.

And check for any disgruntled
ex-employees. Doing that too.

Right. So where are we
with this Kate McMurdoch?

Well, she's not at home, so Sergeant
Maddox is trying to track her down.

Maybe she's done a runner.

Maybe it's a bit early to tell.

(SIGHS)
Imagine devoting your entire life

to working out
how to unravel knots.

Imagine.

Kate McMurdoch is currently on her
way to the Cheddar Gorge.

Mountaineering Club.
They left this morning.

How long for?
Just for the day.

I'll be waiting for her
when she gets back.

'An explosion ripped through the
prestigious mathematics department

at Oxford University
earlier today.

Police and treating it as suspicious
and believe it to be...'

It's up.
Hardly surprising, is it?

'..one fatality confirmed, though a
dozen students and staff treated...'

Wallet, watch and wedding ring.

You should be able to get a positive
ID from those.

Yeah, we'll get them round to his
wife.

At least her last memory of him
won't be...that.

Thanks, love.
Have you got it?

Present, for the baby?
No...not yet.

Well, you suggested it. Yeah,
well, I've been a bit distracted

with the bomb going off.
You know how it is.

All that way.

We don't want to turn up
empty-handed, do we?

No, I'll get onto it. I promise.

Exciting, isn't it?

Yes. That's his.

It has 'always' engraved
on the inside, see?

'Occasionally'
would've been more accurate.

I want to see him.

That's not a good idea.

We can arrange for someone
to visit you if you'd like.

No need.

And we're going to need access
to some of his things. Of course.

His computer.
His phone records, bank accounts.

Help yourself.
You won't find anything.

Oh, were you going to give
one of these lectures?

We all were.

David, me...Adam.

You're a mathematician too?
No, I'm a chemist.

We do the lectures every year.

Mine are usually demonstrations,

chemical reactions,
that sort of thing.

Adam's were always more flashy.

'Maths and the calculus of coitus'
was a good one.

Who knew maths could be such fun,
right?

And what is
the Lockston Foundation?

Donald. My father. He bankrolled
Adam and David's research.

Adam got to do whatever he liked
and Dad picked up the bill.

Oh, can we continue this outside?

I have a lecture to give.

Surely, in the circumstances -

I prefer it.

Keep busy.
Better than being alone.

Not good at that.

Five years, we were married.
I should've left him long ago.

God knows he gave me enough reason.
He cheated on you?

Forgive me, but...

was your husband seeing anybody
at the moment?

I don't think so.

I was surprised when he went into
work early this morning.

I thought maybe...another student.

I tried leaving him three years ago.

February 7th, my birthday.

He'd gone to Toronto for a symposium
and I packed my bags.

You waited till he was out
of the country?

I've never been very good
at confrontation.

But even then,
I still took him back.

Hopeless.

I tried hating him, especially after
Paula, but that didn't work either.

Hopeless case, really, so...

Who's Paula?
Paula Guitteau.

She was one of his students
and they had a thing.

Had?
They never last long, Inspector.

The last time they met,
Adam said he wanted to end it.

Two days later,
she started yelling rape.

And did your husband rape her?
No, of course he didn't.

I mean, he never denied having sex
with her, but it was consensual.

For old times' sake.

And you believed him?

The girl had...issues.
She was unreliable.

So the charges didn't stick
and the case was dropped.

Where can we find this
Paula Guitteau?

You can't.

She committed suicide.

Mrs Guitteau?

I'm Detective Inspector Lewis.
This is DI Hathaway.

We'd like to talk to you
about Paula.

Paula loved the garden.

She and Frank used to do it
together.

Before Paula died, she went into
the garden to pick some flowers.

Peonies and forget-me-nots.

And she put them in a vase
and she left them here for us.

And she went upstairs.

This was after the rape charges
were dropped?

I found her.

She'd used a belt
and a hook on the back of the door.

It was her word against his,
you see.

She didn't stand a chance.

Not against the maths superstar.

But they'd had a relationship?

Is that what you'd call it?

We're not exciting, Inspector,
you know?

We're just ordinary.

To Paula, someone like Adam Capstone
must have seemed...

She was flattered?
No, she was just a child.

All he had to do was
click his fingers...

It left her feeling...dirty.

She told him that she wanted
to end it so he er...

Afterwards, she felt so ashamed.

It took me two days to convince her
to tell someone.

"Trust me," I said.

"Tell the truth
and everything will be OK."

So it wasn't Adam Capstone
who wanted to end the relationship?

Nah. No, it was Paula.

She stood up to him
and he wouldn't accept it.

So he made her pay.

How did that make you feel?

How do you think?

I wish only bad things
for Adam Capstone.

What?

Adam Capstone died this morning,
Mrs Guitteau.

Somebody sent him a bomb in the
post.

My God...

Also a number of threatening
letters.

Not from me.

What about your husband?

Frank gardens, Inspector.

Did Paula have other boyfriends?

She never mentioned any.

Well...might have been someone.

(READS) Always remember 060302.

Do those numbers mean anything
to you?

What, like a date or something?

6th March, 2002. Or the 3rd of June
if you're American

but that'd still make her
only about seven.

Sorry. No.

Do you mind if...?

Kate McMurdoch?

DS Maddox.
Have you got a few minutes?

Thanks, Mrs Guitteau.
Right, thanks.

That was forensics.

The bomb was made out of fulminated
mercury packed into a small pipe.

You open the box and...

Boom.
Mmm.

Mercury's not easy stuff to get your
hands on, especially not nowadays.

OK, why don't we check if there have
been any break-ins recently

in warehouses, merchants, labs?

Oh, listen.
I need to make a little detour.

I promised to buy a present
for the baby.

Apparently we're not allowed to turn
up emptyhanded. No, it's bad form.

So, any ideas?
What, me?

Something that says 'Oxford'.
Metaphorically.

Pair of handcuffs?

You know Frank Guitteau's job
is collecting office waste?

Picking up electrical goods
for recycling, that sort of thing.

So? There's mercury
in fluorescent light bulbs.

So, do you want to go back
to the station

and take a closer look
at Frank Guitteau?

What about the present?
Nah, later.

Two years I was on the team.

David invited me to join
after I graduated.

To study knots?

It sounds mad, doesn't it?

But our research -
OUR research?

I still feel a part of it.

And yet you walked away.

Yeah, a couple of months ago.

Adam and David were heading down
a dead end. I steered them away.

And more than that, it was that
study of spiral knot determinants

that led to everything else.

There wouldn't have been
a breakthrough

if it hadn't have been for me.

Afterwards, when Adam and David
presented their findings...

I wasn't even mentioned.

It was like they'd done
all the work themselves.

I'd been photoshopped out.

I went to them.
I told them I thought it was unfair.

And Adam said
all I'd done was the grunt work.

I hadn't made the final connection,

even though it was right there
in front of me.

"Grunt work".

Must have made you very angry.

I yelled a bit, yeah.

Eyewitness said you went...

"batshit in the atrium".

Maybe a little.

Somebody sent David and Adam
Capstone threatening letters.

Not me.

OK. We're done.

As you can see,
I still have some movement.

I've got the full Stephen Hawking
to look forward to.

It's genetic, no known cure.

Is that why you agreed
to fund the Capstones?

To find a cure?

I'm beyond all help.

But if their research can make
a difference after I'm gone,

and I make it possible...

that's got to be worth something,
hasn't it? A legacy.

Better than a blue plaque.

Did you know Adam Capstone?

No. Not very well.

He used to come sometimes with
Elizabeth, Donald's daughter,

but we didn't speak much.

Were either of you aware of the
allegations made by Paula Guitteau?

Well, the... The girl was troubled.

What she did was terrible,
but that was her choice.

Adam was entirely blameless,
is that what you think?

I think it's none of our business.

I suppose you're right.

I should go. Grace'll be hungry.

Grace?
My three-year-old.

She's with the childminder.
She doesn't like to be kept waiting.

Especially when food's involved,
I bet.

You've got kids?
One of each.

A long time since they were three,
mind.

I'll check in later.
We can do some neck stretches.

Gentlemen.

Sarah. She lives in.

Easier to torture me.

I don't know what I'd do
without her. Wither, I suppose.

Would you excuse me for a minute?

Ms Alderwood?

Adam Capstone...
What about him?

You didn't like him very much,
did you?

Adam was a shit, frankly.

Which is how he treated Elizabeth.

How did Donald feel about that?

Donald spends 90% of his day
just trying to get through it.

A large part of my job
is to help him do that.

Now, if that means avoiding ways of
upsetting him, then fine.

So we pussyfoot around the subject,
pretend that everything's OK.

Can't been easy.

I'd do anything for Donald.

Even if I could, I wouldn't get
involved. It's not my place.

Besides, Elizabeth is tougher
than she thinks.

All that self-doubt
and no confidence on the outside,

but on the inside...

just like her mother.

Pure tungsten.

No break-ins here, I'm happy to say.

Everything's kept under strict lock
and key.

So who normally has access to all of
the chemicals?

Students and members of staff.

We er... We each have a key card

and everything has to be
accounted for.

How hard is it to fulminate mercury?
It's not.

You just mix mercury with
concentrated nitric acid

and add the resulting aqueous
mercury nitrate to ethanol. Simple.

So anyone could do it?
If they have the chemicals.

Ah, Professor Dimmock. You're busy.

That's all right. I'm being grilled
by the police. It's very exciting.

DS Maddox. And you are?

Djimon Adomakoh.

Mr Adomakoh is one of our brightest
stars, all the way from New York.

A postgraduate research fellowship
beckons.

Congratulations.
Thank you.

Were you looking for me?

Er...yes, but it can wait. Sorry.

I'm going to need a list
of all students and staff.

Anyone who has access.
Of course.

You take security seriously here?

Students with unlimited access
to chemicals

and the knowledge to turn them
into something illegal -

asking for trouble, don't you think?

(PANTS)

ELIZABETH: 'Mercury's a real pain.

Especially if you spill it.
So, you know, don't.'

MADDOX: She's got loads of videos
online. Lectures, demos. All sorts.

She wouldn't have any problem
getting hold of mercury.

And she'd know what to do with it.

Plus she said she hates
confrontation.

What, you're saying it's easier to
send a bomb than just have a row?

Well, we know she resented Adam's
behaviour

but couldn't bring herself
to leave him.

Which would make her resent him
even more.

And I've seen a lot of grieving
widows, but never one like her.

Right, I'm gone.

I've got to skype Tony. They've
just offered him another year.

Have you said yes?
We are thinking about it.

Well that's...great, isn't it?

Er...yeah.

Yes.

Better prospects. Better money.
Better pension.

We're dead happy.
See you in a bit.

Right, I'm going to scoot too.

What, is it something I said?

No. I'm just going to go and sit
with Dad.

He seems to like it this time
of day. Toodle pip!

My wife's thinking of getting
a new car. Hatchback.

Card.

I think a bike's better.

Stand.

ANSWERPHONE: 'Hi, it's Adam. I'm
obviously being a genius somewhere,

or, more likely,
I've forgotten my phone,

so leave me a message
and I promise I'll get back

just as soon
as I stop being a genius

or find my phone,
whichever comes first.'

ELIZABETH: '..it's useful to have
a mercury spillage kit,

which contains sulphur and lime...'

Brushing up on your chemistry?

She's good, in a Royal Institute
Christmas Lecture-type way.

And I bet you watched
every one of them.

Highlight of my holidays.

Adam Capstone certainly seems
to be enjoying it.

And so does Paula Guitteau.

I've also been checking up
on Adam Capstone's emails.

I don't suppose his passcode's
060302?

Not that simple, sadly.
Never is.

Oh, hang on.

These, he's deleted off the computer
but they've stayed on the server.

They're emails from his brother.
So why delete them?

(READS) Think of someone else
for a change.

Carry on, and I'll kill you.

I'm guessing that's why.

Yes, we argued.

"Carry on, and I'll kill you"?

I was angry. I said some terrible
things and I wish that erm...

You argued about who would benefit
from your discovery?

Yes. Adam was all,
it belongs to the world.

And you disagree?

Why shouldn't we make some money?
We've worked hard enough.

So you agreed to sell
to AKGC Pharmaceutical?

Who have the wherewithal
to develop a product

that will change the world.

What we've discovered is the first
step. The toolbox, if you like.

There's still a long way before
there's a drug on the market.

And if they want to pay us for that,
where's the harm?

Adam didn't seem to think
that money was the issue.

You never do when you have it.

Do you need money, Mr Capstone?

No, as it happens.

Besides, Adam was being a bit
disingenuous.

There's still money to be had.

Recognition. Tenure at a nice,
rich college in the States.

Did like your brother, Mr Capstone?

How can you even ask that?

Yes, we rowed.

Yes, I disagreed with some of the
things he did.

But...Adam knew me better than
anyone,

and I him.

My whole life, there hasn't been
a day that he wasn't a part of.

He was my brother, so never make
the mistake, Inspector,

of thinking that I didn't love him.

How well did you know
Paula Guitteau?

I didn't. I never taught her.
Adam looked after her.

You stood by your brother even
after she accused him of raping her.

Yes.

And after she...did what she did.

Which sort of answers
your earlier question, doesn't it?

Sort of.

Look, I know the emails look bad.

It's the last thing I said
to my brother

and I never got the chance
to put it right.

The deal still going through with
AKGC?

Yes. It always was.

Now, if you'll excuse me,
I have a fundraiser to attend.

It's not that I really feel like it
but, you know, duty calls.

Ah, Inspector.
I didn't see you on the guest list.

Yeah, I'm sorry.
I realise this isn't very
convenient,

but I do have a couple of questions
I need to ask you if that's OK?

Perfectly. Professor Dimmock here
was just about to leave anyway.

Let's go and find somewhere
a bit quieter.

Give my smile muscles
a bit of a rest.

About the only ones I've got left.

Come this way.

Did you know that David was hoping
to sell their research

to AKGC Pharmaceutical?

Yes.

And Adam disagreed?

It was his right.

It wasn't meant to be about getting
rich quick.

So you didn't approve?

Well, the money didn't come
with any strings, Inspector,

but, no, I didn't like it.

And now there's nothing stopping it
from happening.

David had it hard growing up.

In what way?

Whatever David did,
Adam did quicker. And younger.

A levels. Oxbridge entry.

David is brilliant,
but Adam was the truly gifted one.

He could see connections.
Make leaps that others...

..that David couldn't.

On the other hand,
David could do all the groundwork.

Put in the hours,
build the foundations.

And then Adam would come along...

..and steal all the glory?

Well, make all the difference.

And was David jealous?

He understood.

They complemented each other.

Singly, they were remarkable
mathematicians, but flawed.

Together, they were extraordinary.

(SIGHS)
David loved his brother, Inspector.

He'd never harm him.

Not David.

Would you like me to...?

Yes, Thank you.

Came for a top-up.
Help yourself.

This not your thing?

Rubbish at all the glad-handing.

Besides, she likes my full attention
when she's eating.

That's the thing about
three-year-olds.

So set in their ways.

Oh, I've always wanted to go there.

I saw those when I was in Toronto.

It was winter.
They were frozen solid.

Amazing.

Oh, try to keep hold of it,
munchkin.

Always more useful that way.

When did you say that was?
What?

That you were in Canada.
Three years ago.

February, was it?

The same time that Adam Capstone
was there.

How old did you say she is?

It began soon after I started here.

I was vulnerable and Adam sensed it.
Easy pickings.

Vulnerable?
I was lonely.

I'd lost my job at the hospital and
I was going through a rough patch.

My husband divorced me.
I was a mess.

But coming here
was the first step back.

Adam was funny and attentive...

and I...

I adored him.

Or at least I thought I did.

So, what happened when you found out
you were pregnant?

I told him I was going to keep her.

And he made me promise not
to tell anyone who the father was.

Promise? In return for what?

Money?
For a while.

Then Elizabeth found out
about the payments.

Adam fessed up. That was that.

So Elizabeth knew?

Where are we with the grieving dad?

Frank Guitteau? Still digging.
You think he could make a bomb?

Fulminating mercury is not that hard
if you've got the right kit.

Even so, it's a bit specialised,
isn't it?

It's hardly your basic weapon of
choice.

Then there's the hate mail.

That's a major line of enquiry.
So it is.

Professor Dimmock
from the chemistry lab

has given me a list of those who
have access to the supplies.

Start with them.

Maybe one has links to the maths
department we don't know about.

(MOBILE PHONE RINGS)

(SIGHS)

(TUTS)

'This is a message
for Mr Djimon Adomakoh

to call Sergeant Maddox
at Oxford Police. Thank you.'

Police want to see me.

It's not enough.
It's what we agreed.

I need more.
That's all there is.

You owe me.
I owe you what's in there.

I'm calling it a day.
What?

It's too dangerous.
We're not doing anything illegal.

Tell that to the pit boss.

Please, David.

A few more games.
Don't I deserve that?

No, we quit while we're ahead.

And you just get to decide?

That's right.

They'll find out.
You don't know that.

If the police are asking questions,
they will find out.

It's gonna be OK.
We just wait it out.

What else can we do?

Come on.

So the wife knew about the baby?
According to Sarah Alderwood, yeah.

Plus, money from the pharmaceutical
deal her husband opposed.

With him out the way,
it's sure to go through.

And as his widow,
she stands to benefit bigtime.

So that's two motives and
unlimited access to mercury, right?

I think I've got something.

We know that the letters sent
to Adam Capstone

were processed through
these sorting offices -

Wallingford...Thame...

and Kidlington.

And this is a copy of
Frank Guitteau's pick-up itinerary

for the whole of the last month.

On the day the letters were sent,

he had pick-ups
in Thame, Kidlington...

Wallingford.

It's a coincidence, that's all!

Yes, I was in those places.

So what? So were a lot of people.
Hey, it's my job.

Do you handle a lot
of fluorescent bulbs here?

A fair amount.

Do you know how to extract mercury
from them? Of course I don't. Why?

The bomb that killed Adam Capstone
was made from mercury.

And you hold Adam Capstone
responsible

for the death of your daughter.
He was responsible.

You wanted to make him pay
for what he'd done?

I wanted him to be scared.
I didn't want to kill him.

Look...

They were just letters.

OK? Nothing else.

He'd got off scot-free. Like nothing
had ever happened. Whereas we...

Do you know my wife spends
her waking hours

volunteering for every
bloody charity you can think of?

She's more interested in strangers
than she is me.

We just live in this...fog.

I couldn't save my girl
and now I can't save my wife.

I wanted to make him hurt a little.

I could do that, at least.

I'm sorry, Frank, we're going to
have to take you down the station.

16.

Card.

Too many.

Is this necessary?

Your husband didn't say anything
to you about what he was doing?

No!
You had no idea?

Since Paula died, we don't say much
to each other about anything.

David Capstone said he didn't know
Paula.

He obviously gave her tutorials too.

Look, he marked some of her papers.

Yes, Mr Capstone, it's DI Hathaway.

Erm...I need to ask you
a few more questions.

Clarify a few things.

Yeah, see you in half an hour.

David.

We've been through this.

After everything I've done for you?

Go home, Andrew.

What did you get in the end?

Sorry?
For the baby.

Nothing. Yet.

I haven't found the right thing.

Go on.

You should probably tell Laura,
you know.

What?
That you don't want to go.

Look, I just haven't got around
to buying anything, that's all.

Right.

I forgot.

And that's not symbolic.

(CLASSICAL MUSIC BLASTS)
Mr Capstone!

(RINGS DOORBELL)

David Capstone!

Help me!

David!

(SWITCHES MUSIC OFF)

What do I do?

Give me bomb disposal.

David, look at me.

Just put it down very slowly.

I don't wanna die.

Nobody's gonna die.

There's been another explosion.
