Inspector Lewis (2006–2015): Season 6, Episode 4 - The Indelible Stain - full transcript

American academic Paul Yelland faces accusations of racism when he presents his theory on Criminal Dangerousness to an Oxford college and is later found murdered. Married professors Anne and Robert Fraser claim they invited him to raise their department's profile and Robert,who is having an affair with student Nina, points Lewis towards Myra Bennett's anti-fascist group. Yelland also dealt in antiques and had angered two clients with a forgery and furthermore turned out to be the father of a staff member,whose mother he deserted when pregnant. Then Nina is killed after Anne has discovered the affair. Lewis must not only expose a killer whose motive goes back many years but battle with tooth-ache in the light of his fear of dentists.

Come on!
Get him!

Come on, Real Deal!
Come on, Real Deal!

Yes, come on my son!
Come on, Real Deal!

Yes!
Yes!

We now believe
that we have identified...

to protect a citizen...

and wrongful...

I've been asked to let you know -
five minutes, Professor.

Oh, thank you, thank you.

Well, I shouldn't worry.
This audience won't bite.

Ah, ha! They used to.
Times have changed.



Talks at Oxford are a lot more
civilised now, and a lot less fun.

Well, I'll leave you
to compose yourself.

Thank you.

'Plays it wide.
This lad is so fast.'

'So good to see a player take on
the defenders in the modern game.'

'Great skill to the touchline
so it's going for a corner.'

'Can Newcastle make the most
of this opportunity?'

'The centre half has come forward.'

Oh, no!

Dangerousness...
..is the term attributed to people

considered to be a risk
to the public,

but whose behaviour is not
a consequence of mental illness.

In the past, various attempts
have been made to use dangerousness



to try to predict criminal behaviour
before it manifests itself.

But no reliable tool

to measure an individual's
propensity for criminal behaviour

has been available,

until now.

So with the mapping
of the human genome,

it may now be possible
to locate the sequence

responsible for criminal
dangerousness.

And if this is possible,

it could herald a new era
in crime prevention.

And now we believe...

No platform for racists!

No platform for racists!

No platform for racists!
No platform for racists!

Keep my seat warm.
Isn't that a job for Security?

No platform for racists!

No platform for racists!

No platform for racists!
No platform for racists!

No platform for racists!

No platform for racists!

That's your cue, darling.
I hardly need you to tell me.

Ladies and gentlemen,
my mother taught me

the best way to deal
with naughty children

is to ignore them.

They're certainly entitled to their
opinion, incorrect as it may be.

I was ah... just about
to reach my conclusion

and open the floor up for questions.

Are you happy to continue?
Of course.

If you could introduce yourselves,
that would be extremely helpful.

Yes?

Nina Clemens, second year Law.

Given that past theories
of dangerousness

have tended to target
ethnic communities

where poverty
and crime rates are highest,

isn't your proposal
just the latest Trojan horse

by which to introduce racially
motivated social engineering?

I'm merely proposing a new tool,
young lady.

It's up to others
to decide how to use it.

Yes?
Professor Lipton,

senior lecturer in Criminology
and Fellow of Milton Hall.

Professor Yelland, haven't we seen
how others use a similar tool?

Cuba, for example, where the theory
of criminal dangerousness

has been misused to imprison people
before they actually do anything...

mostly, of course,
opponents of the Cuban regime.

Oh.

10, 20... That takes care of food
for a couple of weeks.

I was thinking of a couple
of bottles of good champagne.

Isn't it all good?

You haven't drunk much, have you?
Thank you.

The streets of Catford
aren't awash with the stuff.

Then allow me to educate you.
Ooh. Right.

Would you like another glass?
No, thank you.

What did you think?

Er, of what?
His talk.

Interesting.
As in you think he has a point?

Or interesting as in how can someone
so apparently clever

be so apparently reactionary?

It's not for me to say.
You're allowed an opinion, surely.

I'm just an administrator,
Ms Clemens.

I leave opinions to those qualified
to hold them.

I must say that my reception
here at Oxford

was a bit more robust
than I was expecting.

But... I always hope that
I'm big enough not to take offence.

Professor Yelland, may I introduce

one of our brightest second-year
students, Nina Clemens?

Would the beautiful Miss Clemens
deign to shake the hand

of a racially-motivated
social engineer?

You can't deny,
criminal dangerousness

has always found most favour
amongst those with a racist agenda.

Well, would you hold the Wright
brothers responsible

for the carpet bombing of Dresden?

Or Einstein for Hiroshima?

If they were in a position to
predict how their work would be used

and did nothing to stop it,
then why not?

Professor, would you like
another glass of wine?

Oh, thank you very much.
I've had enough.

Go on. You've earned it.
Well, thank you. Thank you.

It's time Professor Yelland
was taken back to his room.

Why? He seems to be enjoying himself.

I'm very tired, Robert.
And very bored.

It's time to wrap this up.
OK.

It's very kind of you
to walk me back to the college.

Not at all.
The wine was wonderful.

Always a highlight at these things.

I'm afraid I over-indulged.
Isn't that what good wine's for?

- Here he is!
- No platform for racists!

No platform for racists!

No platform for racists!
Ignore them. Come on.

- No platform for racists!
- This isn't over yet, Yelland!

Who said that? Where are you?

No platform for racists!
No platform for racists!

No platform for racists!

No platform for racists!
No platform for racists!

Ta-da!

Just letting Nina know
what a brilliant night she's missing.

Her loss.

I've suggested she meets us
in the college bar after her talk.

If she likes kissing her tutor's
arse so much,

shouldn't we leave her to it?

Focus, William...

on the here and now.

I'm so tired.
You've had a long day.

Yes... yes.

We're nearly there.
I need to sleep.

You shall. You shall.

All those people.

Forget them. Forget them.

They're so angry.
They like being angry.

It makes them feel important.
Come on, nearly there.

Watch this step.

Easy, easy.

OK.

Yelland was furious
about that protest, and the Q and A.

He tried to hide it but he was livid.

Good.

Did you see the local press
scribbling feverishly away?

She almost broke her pencil.

Well, I hope everything
works out as you've planned, Anne.

After all,
you have planned very hard.

I have some work to do. Good night.

Good night, Andrew.

Oh, come on...

How was he?

A little worse for wear, but fine.
Thanks for waiting.

Let me walk you home.

I was meeting some friends
in the bar here.

Right.

I'll try
not to enjoy myself too much.

"They who go
feel not the pain of parting,

"It's they who stay behind
that suffer."

Good night, Professor Fraser.

Night.

Let's not go to the bar.

Nina's already been waiting
over an hour.

Let's find somewhere
to lie down and look at the stars.

How much champagne have you had?
Not nearly enough.

Well, have any more and there'll be
no point looking up at the stars,

because they'll all just be one big
blurry...

What's he looking at?

So what I know is,
he was a visiting academic

by the name
of Professor Paul Yelland.

Postmortem will confirm,

but I suspect cause of death
will be... strangulation.

He was here at the invitation
of the Department of Criminology

to give a public talk.

I was there, actually.
How come?

Well, a friend saw an article
and thought it might be interesting.

And was it?
Not really.

But SPEAKER DESERVES TO BE STRANGLED
is in my opinion a harsh review.

Any sense at this talk
that he was anxious?

No, this wasn't suicide. The door
was forced from the outside.

He'd forgotten his key, and forced
the door in desperation to get in?

The key was in his jacket pocket.

You can do this to yourself.

Apply enough pressure
to the carotid bulbs

and eventually your heart will stop.

But the extent of bruising
around his neck

suggests he struggled hard
to stay alive.

And look at this.

Ah, right. He managed to get
his fingers behind the ligature,

but then the killer was too strong.

What was his talk about?

A potentially new approach
to criminal dangerousness.

Well, right now he must be
the world's leading expert.

Criminal dangerousness.
What?

You don't need a master's degree
in criminology

to tell you somebody who whacks you
and nicks your wallet is dangerous.

Little more to it than that, sir.

Crackpot theories
about why people do bad things

were all the rage when I was a cadet.

As no doubt
were the twin innovations

of suspects having
motives and fingerprints.

There was no DNA testing.
You just had to be bloody good.

But what if good and evil could
be determined at a genetic level?

It's all hokum.

That's what they said
about the earth orbiting the sun.

Bairns aren't born evil.

Given the right circumstances,
people are capable of anything.

That's the second time
you've checked your watch.

Do you have a woman simmering
chez Lewis?

No, I have a dodgy tooth
about to explode chez my gob.

You are aware we have a brilliant
new service now called dentistry?

Yeah. Been there, done that, got the
bloodstained T-shirt. Never again.

When was that?
20 years ago.

You haven't had your teeth checked
in 20 years?

If it ain't broke...
It's probably rotting on the inside.

That's the Tooth Fairy, appalled.

No, it's the Chief Super,

requesting the pleasure of our
company in her office before the...

Too late.

Oh, look, it's Action Man.

Peterson.
Boys.

Ma'am.

DI Peterson and his unit
have been tracking local extremists,

so he may have valuable information
for the investigation.

We've monitored the anti-racist
group that disrupted Yelland's talk.

Myra Barnet.

Figurehead, old school, hardcore.
And other cliches.

We thought they were pretty
harmless, until now.

We still have nothing concrete
to pin on them.

Needless to say, the Vice-Chancellor
was on the phone within minutes.

A guest of the university murdered
on the premises

after giving a talk
where, by all accounts,

university staff and students
tore him apart.

The PR consequences
are obviously horrendous.

The paper are running the headline
LYNCHED, exclamation mark.

From what I saw, he wouldn't
have required much lynching.

What, you were at this talk?
Yeah, with Dr Hobson.

I was just keeping an eye on things.

The university need this wrapped up
quickly. And so do I.

The Director of the Department of
Criminology called me personally

to request some protection for
Professor Yelland during his stay.

I turned it down as unnecessary.
On advice from us.

Our intelligence said no one had
any interest in targeting Yelland.

You couldn't
have got that more wrong.

That's why we think the motive was
personal rather than professional.

Liaise with one another
and let's find who did this quickly.

Yes, ma'am.

Well, why are you sitting there,

looking at me
like dogs being shown a card trick?

Come on, answer the phone.

Come on.

Sorry!

Talking to local radio.
You could have done that in the car.

The acoustics would be terrible.
I needed to sound authoritative.

What did they want to know?
Why Yelland was killed.

The spotlight is upon us, darling.
It's time to dance.

So what did he look like?

We couldn't see much detail,

just his bloated face in the window.
Oh, disgusting.

Will freaked out.
I'm not surprised.

Whenever
we had dissection in Biology,

he always had a note from home
to excuse him.

Weird to think you were listening
to him just an hour earlier.

Not just listening. Accusing
him of being a closet racist.

You probably
pushed him over the edge!

If only I had
that kind of power over men.

You don't do too badly.
What's that supposed to mean?

The hot professor.

Will. To name just two.

Will?
Emily, Will's just a mate from home.

Are you sure that's all he is?

Yes.

How was your run?
Knackering!

I told myself I was being chased by
the dead guy and did a personal best.

I thought you were going to run
again, Nina?

After much deliberation, I concluded
my running days are behind me.

You loved it.
I stopped loving it.

And I stopped loving watching
skinny doggies

run round after a teddy bear
on a trolley.

Are you going to shower now
or can I nip in?

Be my guest.
Thanks.

I've always wanted to learn
how to run.

There's not much to it.
It's like walking, only faster.

Strangled by his own tie.

An advert for dress down Fridays
if ever there was one.

I can confirm cause of death

was asphyxiation
due to strangulation.

He was two and a half times
over the limit when he died,

with the sleeping drug Zolpidem
in his system.

Toxicology puts ingestion at around
the time he was giving his talk

or just after.

Enough to make him more compliant
to kill.

Any amount would have that effect.

This particular brand
activates relatively slowly,

but would synergise with the alcohol
to speed up the conking out process.

The conking out process being...?

An internationally-recognised
medical term.

Ann-Marie.

Is that it?

I've pushed your boat into open
water, Robbie. Get rowing.

You wouldn't have anything
for a bad tooth here, would you?

I can take it out if you like.

Course, you'd have to be dead first.

Julie?

Is this all the evidence from
Yelland's room? Yes, sarge.

I've got an open envelope
with no letter.

That's everything.
OK.

Gurdip, I need your massive geek
brain to crack a laptop password.

It shouldn't be too taxing. Then
you can get back to online poker.

Yes, I've got it.
I'll ask her and get back to you.

Thank you. Bye.

Can I help you?

Inspector Lewis,
Detective Sergeant Hathaway,

to see Professor Rand.

This doesn't have to be a problem.
Whichever way we spin it,

the events may be catastrophic
for the department. I agree.

What happened to Yelland in his room
in your college, Andrew,

had nothing to do with what happened
during his time with us.

Did you get to speak
to Professor Yelland at all?

I served him wine.
But other than that...

Did you notice anyone unfamiliar
hovering around

who might have...
slipped something into his drink?

There were lots of people.
It was a public lecture.

I didn't know everyone.

They're all after Professor Rand
for a soundbite now,

press, local radio.
She's in her element.

Not the shy retiring academic type,
then?

Anne? You must be joking.

I once walked past her office

and heard her on the phone,
shouting at him.

At who?
Yelland. She sounded furious.

About what?
I don't know.

But she was calling him a liar
and a fraud about something.

You won't tell her I told you,
will you?

It could put me
in a very awkward position.

We can't promise anything,
Ms Hunter, but...

Lilian, please.
We're nothing if not discreet.

Come!

Inspector Lewis and Detective
Sergeant Hathaway to see you.

I hope we haven't come
at a difficult time.

Not at all.

Can you tell us
why you felt it necessary

to request police protection
for Professor Yelland?

An academic from
an unknown American university,

pushing an improbable twist
on an old theory...

hardly the ace of spades
in a pack of hate figures.

Actually, he and I were students
here at the same time.

He was a high-flying postgraduate
back then.

I don't think
you're seeing the whole picture.

Perhaps because it hasn't been
framed very well, Professor.

Yelland believed bio-technology

could breathe new life into
predicting criminal dangerousness.

Letter to The New Scientist,
at best.

I think you're underestimating
Yelland's proposition...

unlike the vociferous crowd outside.

Rent-a-mob,
according to our colleagues.

Vocal but harmless.

With all due respect, somebody must
have wanted to do him harm

because somebody did.

Look, the truth is,

we wanted to develop Yelland's talk
into something of an event.

Robert!
An event?

To maintain the profile of the
department within the university.

And beyond. Let's not be coy.

My wife never has less than
one eye on 'beyond'.

I came across an article by Yelland
a few months ago in a minor journal

which gave him a few pages
to lay out his vision.

So you invited him to Oxford
to deliver this talk

with the sole purpose of stoking up
some controversy for your department?

In a nutshell.

There's somewhat more nuance to this
than my husband is presenting.

We invite an academic
with an interesting point of view,

put a few articles in the press
to stir up the locals.

The protesters
outside the lecture building?

That was easy. Robert's involved
with a little anti-racist group.

All white, of course.

Happy to give self-righteous
indignation an airing

once in a blue moon.
Isn't that right, Robert?

Yes, darling. Spot on.

Yelland was well compensated.

I even went to his room to check
if he'd suffered any ill effects.

You went to his room?

I may be many things, Inspector,
but I'm not a monster.

Is it just me, or does the air
smell cleaner out here?

No, it's not you.
Inspector!

I'd like to confess
to murdering my wife.

Sir?
In advance of the inevitable.

In my experience, the ones
who talk about it never do it.

I know she appears combative. She's
just protective of the department.

And her career.
I understand.

Just as you left, I remembered
something shouted from the crowd

as Nina and I walked Yelland
away from the lecture building.

Nina?
One of my students.

"This isn't over yet, Yelland!"

Male or female?
Female.

And even though Yelland was pretty
drunk, it seemed to shake him up.

I thought you should know.
Thank you.

Sure.

The woman who disrupted his talk...
Myra Barnet.

Maybe she was threatening
to finish off what she started...

the humiliation and destruction
of Professor Paul Yelland.

If you're double glazing,
I don't want it.

Jehovah's Witness, I don't need it.

Changing my gas supplier...

you're all as crooked as each other
so it's a general "no, thanks".

We're the police.

Please, have a seat.

Why did you disrupt Yelland's talk
at the university?

To convey the strength of feeling
against his racist proposition.

"We"?
The anti-racist group I belong to.

Is Robert Fraser a member?

You'll have to ask him.
He told me that he is.

Then you have your answer.

Wouldn't it be courteous
to have that thing turned off?

I'm at work, not at the theatre.

Excuse me, sir. Hello?

Do you think it's possible
your group has members

who want to make the message stronger
than mere protest?

You mean do I think any of our
members killed Paul Yelland?

Do you?
Medgar Evers famously said,

you can kill a man
but you can't kill an idea.

I've seen nothing
to make me disagree with that.

When Professor Yelland was
escorted out of the lecture theatre,

somebody shouted,
"This isn't over yet, Yelland!"

Did you hear that
after you were ejected?

No.

Are you willing to give me a list of
names of the members of your group?

Oh, I'm sure your
colleagues have us all on file.

I think you overestimate
your significance.

I have no ambitions
towards significance, inspector.

The struggle, always,
is to stay relevant.

Is that all?

Spare me from armchair lefties
and their cheap disdain.

What was the call?
Gurdip's made a breakthrough.

Yelland has two email accounts.

One for Paul Yelland,
Professor of Criminology,

writing to all and sundry about his
work.

And the second?

An email account
for a small business he was running.

If you collect figurines,
or things of that nature,

and can't find
the last piece to complete the set,

Yelland's your man.
Was your man, Gurdip.

That sandwich is making me hungry.

Hi there.
Robbie.

It's a shame you're too chicken
to get your tooth seen to.

This sausage is delicious.

As will be this soup.
Mm.

So, Yelland had a sideline. Sourcing
and supplying rare collectables.

Mm. He had a couple of pieces in his
suitcase, waiting to be delivered,

but he also had a substantial
sum of cash in his suitcase,

having made a delivery
two days earlier.

Which was?

Applique Palermo vase to a local
couple, Hazel and Brian O'Brien.

Brian O'Brien?
I know.

What were his parents thinking?
Or drinking.

It's part of the "Bizarre"
range of ceramics.

Highly colourful,
highly collectable.

After they met Yelland
and paid for the vase,

the O'Briens believed it was a fake.

They demanded their money back.
Yelland refused.

Brian O'Brien became abusive
and then personally threatening.

"Return our money forthwith."
Who says "forthwith" any more?

I think they're trying to sound
like solicitors with menaces.

"This is your last chance.

Ignoring me is the most stupid thing
you could do. Trust me."

What?
"This isn't over yet, Yelland."

You have no idea who sent this?
It's not the first one.

A few times I've had calls that
are just silent on the other end.

Well, I can hear breathing but...

The number's withheld?
Uh-huh.

Robert, you...

don't think it's your wife, do you?

Anne doesn't know about us.
As far as you're aware.

If she did, she wouldn't hide behind
anonymous texts and silent calls.

Whatever she had to say would be
to your face, and extremely scary.

Perhaps we should cool things
for a while.

Nina. You're beautiful. Clever.

You've fought tooth and nail
to be here,

unlike the privileged majority
who consider it their birthright.

It's bound to cause some resentment.

This isn't just resentment.
It's racist garbage.

No, it's just nonsense, Nina.
Don't let it get to you.

Ah.
Who is he?

Her Criminology professor.

Married.

Nina's moving on, William.

Why don't you?

So you follow up
on this O'Brien lead.

I suppose I should liaise
with Peterson's unit.

What do you think Hobson
would see in Peterson?

Who knows?

Yeah, Julie.

'Sir, the fingerprint results
are in. Have you got a pen?'

Yeah.
'So two sets of fingerprints...'

OK, so two sets of prints on the
outside handle of Yelland's door,

one of which belongs to Professor
Anne Rand.

Fits with what she said about going
to Yelland's room after the talk.

Why is Rand on our database?

Drink driving two years ago.

Criminologist, heal thyself.

OK, that's great. Thanks, Julie.

So, as well as Yelland's
fingerprints,

we've got two unknown sets on
the envelope we found on his floor,

one of which matches
the unknown print on the door handle,

plus one known print on the envelope
belonging to an Adam Pettle.

No one heard of gloves?

So let's start with Mr Pettle
and work our way out.

So what do we know about him?

Local boy. 24.

Convictions for assault and breach
of the peace, all during demos.

Anti-Nazi, anti-war,
anti-globalisation.

In fact, anything worth being
anti about in the last six years,

he was there, hitting someone
or breaking something.

How was he
when your boys picked him up?

Pretty cool.
But then he is an old pro.

Actually, I saw him
at Yelland's talk.

He was almost certainly
put on the inside

to kick off
if Myra couldn't get through.

Maybe he's decided
to step it up a league,

not just to hit this time
but to kill.

For the tape, I'm showing Mr Pettle
an envelope

which we recovered
from the crime scene.

Do you recognise this envelope,
Mr Pettle?

No.

Can you explain why we found a set
of fingerprints on this envelope

which exactly match your own?

No.

Allow me to rephrase the question
to help you focus more clearly on
your answer.

Can you explain why this envelope,
with your fingerprints

and Paul Yelland's fingerprints all
over it,

was found in his room
on the night he was murdered?

What was in the envelope, Adam?

Let's try another one.
Did you kill Paul Yelland?

He's like the three wise monkeys

rolled into one bloody-minded
urban guerrilla.

What's your instinct?

Well, he isn't exactly
sweating like a killer,

but he's holding on to something.

The complete set
of Yelland's business emails, sir.

Thanks, Julie.
Any more on the O'Briens?

No, but the camera footage you
wanted is ready in the CCTV room.

Cheers.

I'm still printing the emails from
Yelland's personal account, sir.

Right, thanks, Julie. Go through them
with a flea comb, fetch me any fleas.

Yes, sir.

Laura! You've managed to pinpoint
the exact time of death

and the person responsible?

'Well, in an ideal world,
my answer would be yes to both.'

I'm calling you to let you know
that I've managed to get you

an appointment with my very very
good, very very popular dentist.

Ah, much as I'd love to, I am in
the middle of a murder investigation.

'Well, the dead can wait.
My dentist can't.'

8:30, Robbie.
Likes his patients to be punctual.

Arrive late and he gets very stabby
with the hypodermic.

'Bye.'

Come in.

Nina...
I just wanted to check you're OK.

Call me.

That your thing, Professor?
Clever, inner city black girls?

Who the hell are you
and why are you in my office?

I'm a friend of Nina's and I'm
here to tell you to leave her alone.

I'm calling security.
Good idea.

We can tell them all about how
you've been abusing your position.

While we're at it,
we could tell your wife.

How dare you come
to my place of work?

Leave... her... alone. From now.

For good.

Stop dipping your wick
into the student body.

Got it?

As an international
centre of excellence,

we attract many leading academics
from around the world.

Nothing like this has ever happened
before.

You can imagine how shocked we are.

Thanks. Goodbye.

Your post, Professor.
Thanks.

In goes Professor Lipton...
And on.

OK, rewind.

Stop.

Can you zoom in on that?

Well, well, well.

Give me your phone!
What?

Before you have a chance
to delete any texts or voicemails.

What are you talking about?
I am assuming this is true.

You're having sexual relations
with a student. Again.

Where did you get this?

I was sent it in the post.
I want your phone, Robert.

Now, please.
Don't do this, darling.

I want your phone.

This is nothing but a malicious lie

designed to slander me
and then humiliate you.

Why, God knows. Maybe the sender is
jealous of the attention you've had.

I want your phone.

There's nothing to find, and I urge
you to resist your desire to look.

Please, don't let them do this.

Trust me.

And the other one.

We know you visited Milton Hall
College after the talk.

We need to know why.

I wanted to give something
to Yelland.

What?
A letter from my mother.

You delivered the letter?

They were both students here
almost 40 years ago.

He pursued my mother while she was
in a relationship with another man.

He managed to split them up
and win her over.

After completing his master's, he
was offered a research scholarship

in a southern university
in the United States.

She followed him. Had to.

Why?
Because she was pregnant with me.

Yelland was your father?

Biologically.

When it became clear
that having a half-caste child

would be problematic for his career,
he sent us home.

Wasn't it somewhat coincidental,
Ms Hunter,

that your long-lost father
was to give a talk

at the very department
where you now work?

It's best to tell them.

I wanted to confront Yelland
about what he'd done.

I showed Professor Rand a somewhat
controversial article he'd written

and suggested him as a speaker.

When exactly did you find out
that Yelland was your father?

My mother told me a few months ago,

the day before she killed herself...

in a long letter
explaining everything.

The letter you slipped under
Yelland's door?

She never saw him again
after we came back.

She saw herself as trash...
second-rate, disposable.

And then she started to drink.

I wanted Yelland to read what he'd
done to her, in her own words.

We have an envelope from Yelland's
room, Ms Hunter, but no letter.

I'm sorry... I...
I'm not sure I understand.

We believe the killer
must have taken it.

There were four sets of fingerprints
on the envelope.

Yelland's, yours,

and another, belonging to a lad
by the name of... Adam Pettle.

You know him?
Yes.

Adam's my brother.

So Adam Pettle was holding something
back. His sister-in-law.

When you showed him the envelope,

he must have assumed Lilian had put
it in Yelland's room and killed him.

Question is, did she?

What did you make of that story
about her mother?

I was watching her quite carefully.
She seemed genuine.

But why deliver the letter, kill
Yelland and take the letter back?

Maybe she wanted him to read it
and weep, emotional revenge.

Then her and hubby garrotte him,
physical revenge.

She takes the letter back cos it's
the last words of her dead mother.

Leaving the envelope?

What's a clue
but a mistake by another name?

It's so good to see you.
I didn't tell them anything.

Well, there's nothing to tell.

Come on, let's get you home.

They only kept you in that long
to make you sweat.

Miss Clemens?

Professor Rand.

I know my husband has asked you
to meet him this morning.

You're not the first, you know.

He'll try and persuade you that
you can continue to see one another.

I... Look, with...

You can't see him any more, Miss
Clemens. I simply won't allow it.

Excuse me?

I can't have you sent down
over this,

but really believe me
when I say that I can and will

make the remainder of your time
at Oxford extremely difficult.

Are you threatening me?
Of course.

Now, as a bright girl on the make,

I'm sure you'll listen carefully
to what it is I want you to do.

Professor Lipton.

Detective Sergeant Hathaway,
how good to see you.

Have you got a moment?
Yes, of course, come in.

I was wondering how long it would
take you.

How long it would take me
to do what exactly?

I assumed you've been looking at the
security film from the porters' lodge

from the night Yelland was killed.
Yes.

And you will have noted the time
at which I entered the college

and the time I subsequently left.
Yes.

And you'll need to ask what exactly
was I doing here for that hour? Yes.

I wanted to dig out a few papers
in the wake of the Yelland lecture.

I'm ashamed to say that I dropped off
when reading one of them.

It's rather alarming

to realise one's faculties are
showing signs of crumbling away.

What papers, may I ask?

They related
to the theory of dangerousness.

The impossibility of measuring it.
I took them home.

I give tutorials here,
very little else.

Occasional midday snooze.

And reading...
Reading?

A Tale of Two Cities.

Oh, well, in this case, re-reading.

Yes, I like to come here to read.

Robert.
Hi.

Thanks
for agreeing to meet so early.

When you texted at six this morning,

I assumed it must have been
from my rancid little stalker.

I almost deleted it without reading.
Anne knows.

What?
She received an anonymous letter.

At your house?
No, at work.

The same person who was texting me?
Possibly.

God, Robert, what's happening?

What did she do?

She was surprisingly calm.

Perhaps not so surprisingly.

She's the most controlled
person I've ever met.

I denied everything.

It's so good to see you.
I don't...

think this is a good idea
any more, Robert.

What? I've loved the time
we've spent together, but...

I think we should bring it
to an end.

I've been thinking about this...
Nina, please.

You're hurting me.
I need you!

Let go!
Nina, this...

This doesn't have to be
the end of us.

There's no direct line back to you.
I'm careful.

Find someone else
to give you the thrill

of sneaking around
behind your wife's back.

Because that's what really
turns you on, not being with me.

Betraying her.
That's not true!

Goodbye, Robert.

You cold little bitch.

Thanks.

You just made this so much easier.

It's all right.

OK, fine. Keith Poland?

Yeah, that's us.
OK, surgery two.

Come on, let's go.
Lauren... Let's go!

Patricia Hutchison?
That's me.

Upstairs, first door on your left.
Thank you.

Fred Mclintock?
Yes.

The hygienist is ready
if you just want to pop through.

James?

Gurdip has found Yelland's vase
on an online auction website.

It seems the O'Briens
are trying to recoup their losses

by palming off
what they believe to be a fake.

The bids had started to come in

so I bought it outright
and will collect it at 9am.

I'll be right with you.
'I haven't told you where I am yet.'

Wherever you are, I'm on my way.
Pick me up on your way past.

How do you want to play this?

Well, we're collectors.
We establish their identity,

we establish they've got the vase,

and then we show them
our warrant card.

And what if it turns nasty?
You take the biggest one.

What if they're both the same size?
We do paper, scissors, stone.

After you, Mr Hathaway.

Thank you, Mr Lewis.

It can't be them!

The arrangement was to be here
at nine with the vase.

It's nine, and they appear to have
a vase-sized box.

Can you see these two killing
Yelland?

Perhaps very slowly.

Mr Hathaway?
Hazel?

How do you do?
This is my colleague, Mr Lewis.

Hello.
Pleased to meet you.

I presume Brian couldn't make it?

Oh... we use a male name online...

just in case people think they
can take advantage of two old girls.

Her real name is Edna.

Well, my name isn't Mr Lewis,
it's Inspector.

Mr Inspector?
No, Inspector Lewis.

This is my colleague,
Detective Sergeant Hathaway.

Have you got the cash?
We're police officers.

Don't worry, we trade with anyone,
even the rozzers.

No, I don't think
you quite understand.

We are police officers and we'd like
you to accompany us to the station

to answer some questions
about the murder of Paul Yelland.

That man ripped off a lot of people!

And you were about to do the same
to us.

This was going to be a one-off
for us.

But he made a business out of it.

Did you go to the university
the night he died?

It's a free country
last time I looked.

Did you call,
"This isn't over yet, Yelland"?

Free country, with free speech!

What wasn't "over"?

We wanted to try and scare him
into giving back our money.

And that's all?
Do I look like a killer?

Well, you don't look like a "Brian".
Appearances can be deceptive.

Come on.

It's Nina.
I'm very sorry to bother you,

but I really need to see you.

If Yelland was ripping off
a lot of people,

that's a lot of
potential motives for killing him.

But why take Lilian's mother's
letter?

Sir?
Yes, Julie.

I've gone through Yelland's personal
emails.

There's a correspondence
you might be interested in.

Between him and who?
Professor Anne Rand.

Why didn't you say you had
private correspondence with Yelland

when you were questioned?
I didn't think it was relevant.

Surely you can do better than that.

I was embarrassed that
I was asking the man for a favour.

To help find you a position
in America?

So were you, like he says,
stringing him along,

pretending to find him
a position in Oxford,

while he was actively trying to find
you a professorship in the States?

I was only surprised
it took him so long to realise.

And when he did, he threatened to
cause you a great deal of trouble.

You think I invited him over
to kill him?

Well, say I had killed him.

Why go to all the trouble
of garrotting him with his own tie?

It's a little self-indulgent

compared to the more clinical
alternatives, wouldn't you say?

I wouldn't know.
I've never killed anyone.

The emails suggest you had a great
deal to gain from Yelland's death.

And now he can no longer obstruct
your American ambitions.

It's an interesting theory.

But I assume that's all it is,
or you'd have arrested me.

The emails give you motive.

CCTV places you around the scene
at the time Yelland was killed.

Around but not in.

Purely circumstantial.

If there is any evidence
linking you to Yelland's death,

it will eventually be found.

So this is what? An opportunity to
confess and save the taxpayer money?

Yes, if you're guilty.
IF guilty.

If, Detective Sergeant.

Only two letters,
but a very big word.

Laura, before you tell me
how very, very busy your dentist is,

let me explain.

'Hathaway called me
as I was about to go in.'

'We have a new lead...'

I'd like to hear it, Robbie.
Just not right now.

We really appreciate
you coming in to do this.

We are trying to contact her family,

but they're in the West Indies
visiting relatives,

proving difficult to locate.

Ready?

Yeah.

Yeah, that's Nina.

How?
Severe blow to the back of the head.

Professor Lipton was Nina's tutor.

Have a word with him, also the
university counselling service.

See if there's anything
we ought to know about there.

Black, working class girl
trying to make her way

in the most rarefied, elitist
environment in the country.

Did she feel alienated,

marginalised, ostracised enough
to fall in with bad company?

Sir. Also, any possible link
to the Yelland case?

She was at that talk and walked
Yelland home from the college

with Robert Fraser.

We shouldn't rule out tit for tat
by the far right.

'No, we don't rule anything out.
Let me know how you get on.' OK.

There's something I didn't
want to mention in front of them.

The blow to Nina's head would have
caused massive external haemorrhage.

And yet...
There's little blood with the body.

A very small amount of coagulant.

She wasn't attacked there?
No.

Just stop it!

Take a seat, Emily.

I need you to think really hard.

Is there anything you know of
in Nina's life

that might have led
to this happening to her?

Anything at all?

I don't think so.

Will seems devastated.

They've known each other
since childhood.

Well, at least he has a friend
like you to support him.

That's not all you want him to be,
though, is it?

He barely sees me.
Not how I want him to.

How does that make you feel?

Emily?

It's my fault.
What is? What's your fault?

She was so beautiful.

And clever.

I just wanted him to notice me.

What did you do, Emily?

I just wanted her to go.

I wanted her to feel
she didn't belong here,

so she'd leave...
and I'd have Will to myself.

What did you do?

I sent her texts.

Horrible, anonymous texts.
And silent calls to her mobile.

Anything else?

I sent an anonymous letter

to the wife of a professor
she's been having an affair with.

Which professor?

Emily, I have to ask you this.

Which professor was Nina Clemens
having an affair with?

Robert Fraser.

Come in.

Shocking events, Detective Sergeant.

Our little world has gone mad.

Please take a seat.
Thank you.

Brilliant young girl...
taken like that.

I have devoted my career to trying
to understand the competing forces

that lie behind what we call
criminal behaviour...

well... as, of course, have you
from your side of the fence...

what it is that makes somebody
cross that line, when others don't.

It's not always clear.

Even I find I can't better
Jean Renoir's observation

that "the real hell of life
is that everyone has his reasons".

But what reason would anyone have
to kill Nina? You're her tutor.

Did she say anything to you
in the days before her death

that would shine any light on that?

She did call and ask to come and
see me, just hours before she died.

She confessed that she was having
an affair with Robert Fraser,

and that his wife had warned her off.

She was also receiving
anonymous text messages.

Vile, racist stuff.

She suspected that
Anne was sending them

to frighten her into leaving Oxford.

Oh, but how rude of me.
I haven't offered you a cup of tea.

No, I'm fine.

I'm making one for myself.
Just as easy to make two.

In that case, thank you.

Good man.

"It was the best of times,
it was the worst of times,

it was the age of wisdom,
it was the age of foolishness..."

"..it was the spring of hope,
it was the winter of despair..."

"..we had everything before us,
we had nothing before us,

we were all going direct to Heaven,

we are all going direct
the other way."

Darkness and light.
Death and resurrection.

Social revolution and the brutality
of the mob. No book has more.

Sugar?
One, please.

Will?

So we have two independent reports

of a relationship between
Nina Clemens and Robert Fraser.

Nina told Emily
and Professor Lipton.

Emily was motivated by love for a boy
who only had eyes for Nina.

Whoever killed Nina
was motivated by what?

Love spurned?

Jealousy?

Hatred? Revenge?

We shouldn't rule out
a racist assault.

Nor a link to Yelland's death.

No.

God, what a mess
these kids have got themselves into.

OK. Bring them all in.

The adulterous husband, the
humiliated wife, the unrequited boy.

Sir!

We have a report of a disturbance
at Robert Fraser's residence.

Come out, you murdering bastard!
Please come quick!

Just hurry up! Just hurry up!

If you're not gonna come out,
I'm just gonna have to come in.

Did you tell your husband to break
off his affair with Nina Clemens?

Robert doesn't do "affairs".

He does periodic infatuation

with girls too starstruck
to see the wood for the trees.

So you helped Nina Clemens
see the wood...

I knew Robert wouldn't finish it.

He only knows how to initiate.

So I go directly to the girls and I
explain the situation very clearly.

And the smarter ones get it
and comply.

And the less smart?
I kill them.

Do you think this is a joke?

I think it's embarrassing
and humiliating

that an academic of my standing
should be put through this indignity

by a man she's stood by and nurtured
for 20 years.

You repeatedly insist
that you're an unlikely suspect

because of your standing.

Now, in the cases of Paul Yelland
and Nina Clemens,

you actually have
very strong motive.

At this moment my instinct
is to reach across this table,

shake you by the lapels, and demand
that you stop being so ridiculous.

But despite my "very strong motive",
I'm quite able to control myself.

All this... death...
All these murders.

First Paul Yelland
and now Nina Clemens.

You admit the affair
between yourself and Nina Clemens?

Yes. Which she broke off
the day she was found dead.

I know this might look...
How might it?

That I may have killed her
in a rage for rejecting me.

And did you?

I...

loved her.

I can't tell you how many murderers
I've heard saying those words,

in exactly the same way.
And you know what?

They all meant it.

I didn't kill her.

When you asked Nina
to end her affair with your husband,

how confident were you
that she'd comply?

I didn't take her word for it.

I followed her to where I knew
she was due to meet Robert.

She ended it all right.

How was your husband left?
Upset.

It bothers you, doesn't it,

that he had feelings for her,
that he might have loved her.

First and foremost,
Robert loves himself!

First and foremost, that may very
well be true, but after that...

do you think he loves you?

I don't think you do.
You can think what you like.

Thank you very much. I tend to.

Let me ask you another question.

Do you think your wife killed Nina?
Murderous rage isn't her style.

Isn't it possible
that she killed Nina

to make it look like
the murderous rage of someone else?

Like... you.

Me?

Why in God's name
would she want to frame me?

Did you know she was trying to find
a position in America?

What are you talking about?
Without you.

What?
I'll take that as a no.

She was using Paul Yelland
to explore the possibilities.

We have their email exchanges.

She wanted to open a new chapter
in her career.

New college,
new position, new country.

You're not mentioned.

I don't believe you.
Try, because you should.

No, she wouldn't.

Perhaps the idea of fitting you up
for Nina's murder

appealed to her sense of justice

after all you've put her through
over the years.

Anne would never do that.

How well do any of us know anyone,
Professor? Really?

Do you think
her husband killed Nina Clemens?

Robert Fraser's a philanderer,
not a killer.

Anne Rand, on the other hand,
must rank

as one of the most ruthlessly
ambitious people I've ever met.

What about the boy? Will?
According to Emily,

he's carried a torch for Nina
since they were at school together.

He sees her with another man, older,
more powerful. He can't compete.

If Will can't have her, nobody can.

Apparently he hasn't
said a word in the cell.

He just stares at the floor
in silence.

Emily coughed to the texts and the
anonymous letter to Professor Rand.

What if she confessed
to the lesser crimes

so as to distract us
from her greater one?

They are smart kids.

If she did kill Nina Clemens, she'll
be thinking she's got away with it.

Surprise her. Push her harder.

Excuse me... Dr Hobson.

Laura.

Robbie, I need you
to come and see me. Now.

Hello, Emily.

May I, please?

Yeah...

Thanks, Laura.
No problem.

Speak later?

He came to discuss
some forensic results.

And to invite me to dinner.

Ah, right. When?

Never. Not my type.

So... talk me through these.

Well, these red and blue fibres
are wool,

and they were found
all over Nina's body.

Head to toe. Front and back.

There were fibres in her nostrils
and nasal passage,

suggesting she fell face
down onto a rug,

and was alive long enough
to inhale a few.

So Nina was hit on the back of the
head and put on the rug still alive?

Then rolled up in it and transported
to where she was dumped.

But no rug by the body.

No.

And the thin mustard-coloured fibres?
From the head wound.

Cotton, from book cloth apparently.

Book cloth?
Yeah.

Not used so much now, due to cost.
But in the past,

textbooks, volumes of reference,
compendia etc,

were all covered with book cloth.
Right.

Sorry...

I messed your dentist around.

Forgiven.

You must think I'm horrible,
sending all those things.

It's not my place to judge.
If you'd asked me six months ago

if I'd be the sort of person to
send disgusting texts and letters,

I'd have said you were mad.

Emily, is there something else you
want, or need, to tell me

in relation to this?
Like what?

Like exactly
how far you were willing to go

to get Nina out of the way so
you could have Will to yourself?

You think I killed her?

How could you possibly think that?
You and Will have strong motives.

Will loved her!
That was the whole problem!

Did he love her too much?

He had an explosive temper.

He couldn't have hurt Nina.

You don't know him.
And you do?

These belong to Nina's tutor.
I'm going to return them to him.

Yep.

'Where are you?'
Just finished with Emily.

She's shaken up.
I think she's told us everything.

Either that
or she's a damn good actress. You?

I'm on my way to catch up
with the SOCOs

in that woodland
where they found Nina's body.

We reckon she must have
been dumped there

rolled up in a carpet
or a rug of some kind.

I'm going to drop off some
of Nina's tutor's old papers,

see if he can remember
anything else of use,

and then I'll come and join you.

I remembered
this was in the kitchen.

It's Professor Lipton's as well.

One of a set, I think, but I
could only find this one. Thanks.

Ms Hunter?

Detective Inspector Hathaway.

Still just a sergeant.

Um, I'm returning a couple
of Professor Lipton's papers

and a book that was in
Nina Clemens's possession when...

Very good of you. Come in.

I'll tell Professor Lipton
you're here. Thanks.

Sir! Sir!

Sir.
'James?'

We've found the rug,

about a mile away
from where the body was.

The size is...
About five foot by eight.

'Yeah. How did you know that?'
Because I'm in Lipton's front room,

looking down at where -
Detective Sergeant?

Let me take those.

Come through.
He won't be a minute.

Damn you!

I understand you've brought
some of my papers back.

Yes. And a book. I gave them to...
Lilian, yes.

Yes, well, I'm afraid
I've gradually taken the liberty

of extending her administrative
remit to include me.

Are you married?

No, well, then as a fellow bachelor,

you understand I need all the help I
can get on the domestic front.

Inspector Lewis.
Ms Hunter.

And duster!

Oh, whenever I'm here,
I give the place a quick once over.

Andrew's... Professor Lipton's
a confirmed bachelor.

I think he stopped noticing
the gathering dust years ago.

Sergeant Hathaway's just inside.

I'll let them know you're here.
Thanks.

Inspector Lewis!

I feel honoured to be the focus
of so much police attention.

Do you have some unreturned papers
for me too?

I'm afraid not.
Just a couple of questions.

We found the rug

that Nina Clemens's body was rolled
up in prior to being dumped.

I see. Well, that is good news.

For us. Less so for you.

You see, the size of the rug

perfectly matches
this discoloured patch.

And its colour matches these fibres
which I've just found on your floor.

Well, the world is full of rugs,
Inspector.

Of standard size and colour.

We also suspect that Nina was
bludgeoned to death with a book,

covered in old-fashioned
mustard cloth.

And I have so many books.

Ipso facto...

as a rug owner and a voracious
reader, I killed Nina Clemens.

Where's the missing volume,
Professor?

I can't keep track of everything
I leave lying around.

Lilian just told me
that she's been clearing up.

What has Lilian been clearing up,
Professor?

Your house?
Or the scene of a murder?

Why did you kill Nina Clemens,
Professor?

Were you jealous of her relationship
with Robert Fraser? Did you want her?

I do not prey upon undergraduates
for sex!

So, again, what has Lilian been
clearing up?

Lilian comes here every now and then
out of the goodness of her heart.

Leave her out of it.
She is entirely innocent.

Well, not entirely, surely.

She served Yelland wine
at the reception.

Ample opportunity
to slip him a sedative.

She's on CCTV going into the college
later that night.

And here she is two days after
Nina Clemens is murdered

giving your place
a good old clean.

Andrew, what's going on?

At our first meeting, you said
you and Yelland met at Oxford.

Coincidentally, Lilian's mother was
studying at Oxford at the same time.

Did you know her, too?
I did.

So, Lilian knows all about you, and
her mother, and Yelland? Doesn't she?

Lilian knows nothing.

If she knew that you were the
undergraduate in love with her mother

at the time
that Paul Yelland showed up,

then she knows or strongly suspects
that you killed him.

What?

Or perhaps not.

Andrew?

I didn't fight hard enough for
your mother when I had the chance.

I have borne my cowardice
all my life

like an indelible stain.
Don't say that.

Would the outcome have been different
if you'd fought harder?

The entire universe
would have been different!

But she chose Yelland.
He stole her!

He stole her and he destroyed her!

When I heard about the suicide...

I tracked him down.

I persuaded Anne to invite him as
the department's next guest speaker.

So his article that you gave me
to show Anne...

was all part of a murder plot?

I wanted him here to confront him,
not to have him killed!

You orchestrated his visit.

And then, after murdering him,
you saw the letter

that Lilian had left earlier
and you took it.

Where is the letter, Professor?

"We had everything before us,

we had nothing before us,
we were all going direct to heaven,

we are all going direct
the other way."

It should remain in the past tense.

"We WERE all going direct
the other way."

Intentionally or not,
you changed the tense.

Did I?
Why don't we check?

I killed Paul Yelland...

because he destroyed the life of
the only woman I have ever loved.

"I made a terrible,
terrible mistake.

"Though he tried, I don't think
Andrew was ever able to forgive me."

"Andrew Lipton is the best man
I've ever known."

And Nina Clemens, Professor?

Whose life did she destroy?

Nina?

Your mother's
letter was on the table.

I left the room just for a moment,
and when I came back it was gone.

I confronted Nina about it,
but she denied taking it.

I don't understand.

She tried to leave. I... I
grabbed her coat, I pulled her back.

She slipped on the rug,
hit her head on that step.

But she was still alive on the floor.

You could have saved her.

You chose instead to finish her off
with one of your beloved books.

Many of the mistakes we make in life
can be rectified.

Sometimes we make a mistake which
can't be remedied, can't be fixed.

We just can't go back
to that moment before.

We're propelled forward.
What do you mean?

Nina had the power to destroy me.

Who'd have taken care of you?

My darling girl...

I couldn't let that happen.

But despite your best efforts,
it will.

And so you needlessly
ended her life.

He is a good man.

He looked after us
when Yelland abandoned us.

He helped me get my job
at the department,

helped me cope when my mother...

He treated me like his own.

Professor Lipton,

I'm arresting you for the murders
of Paul Yelland and Nina Clemens.

You do not have to say anything,

but you may harm your defence
if you do not mention when questioned

something
you later rely on in court.

Anything you do say
may be given in evidence.

Please.

It's all I have left of her.

I'm sorry, Professor.

It's evidence now.

Hear that?
What?

The flapping of chickens
coming home to roost.

If he hadn't killed Nina, we would
never have got him for Yelland.

Now he's going to die in prison.

I've got a strong feeling
he died years ago.

It's poor Lilian who's going to
end up serving that life sentence.

Aargh! Damn it!

You know, Lipton reminds me of you.

Stubborn. Stuck in the past.
Come again?

He allowed his life to be marred
by an experience 40 years ago.

You're allowing yours to be marred

by a dental appointment in 1992.
Hardly comparable.

Well, I've booked you an appointment
with my dentist tomorrow morning.

She's opening up especially.
I'll pick you up at eight.

I'll be going for a jog at eight.
You don't jog.

I just started.

You fancy a pint later? Big match,

stupid-sized telly in a sweaty pub?
I've got a book to finish.

Have you learned nothing
from this case?

Books are bad for your health.
Not if you just read them.

Why don't you invite Dr Hobson?

Get in there quickly
before someone whisks her away.

You said it yourself.

Stuck in the past, me.
