I'm sorry.

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.

They used to.

Times have changed.

Talks at Oxford are a lot more civilized nowadays and a lot less fun.

I'll leave you to compose yourself.

Thank you.

Dangerousness.

is the term attributed to people considered to be a risk to the public,

whose behavior is not a consequence of mental illness.

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

predict future criminal behavior before it manifests itself.

But no reliable tool to measure an individual's propensity for criminal

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 that we have identified...

I hardly need you to tell me.

Ladies and gentlemen, as my mother taught me, the best way to deal with

children is to ignore them.

Well, they're certainly entitled to their opinion, as incorrect as it may

I was 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

communities where poverty and crime rate the 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 already seen how others use a similar tool?

Cuba, for example, where the theory of criminal dangerousness has been misused

to imprison people before they've actually done anything.

Mostly, of course, opponents of the Cuban regime.

That takes care of food for a couple of weeks. I was thinking more along the

lines of a couple of bottles of good champagne.

Isn't it all good?

You haven't drunk much, have you?

I keep.

Streets of Catford aren't exactly washed with the stuff, no.

Then allow me to educate you.

All right.

Do you like another glass?

No, thank you.

What did he think?

Of what?

His talk.

Interesting.

Interesting as in you think he has a point? Or interesting as in how can

so apparently clever be so apparently reactionary? That's not for me to say.

He'll have an opinion, surely.

I'm just the department administrator, Miss Clemens. I leave opinions to those

qualified to hold them.

Well, 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 offense.

Professor Yelland, may I introduce one of our brightest second -year students,

Nina Clemens. And would the beautiful Miss Clemens deign to shake the hand of

racially motivated social engineer?

You can't deny criminal dangerousness has always found most favor amongst

with a racist agenda.

Well, would you hold the Wright brothers responsible for the carpet bombing of

Dresden? Or Einstein?

Or 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 really had enough. Go on.

You've earned it. Well, thank you.

I think it's time Professor Gillan was taken back to his room.

Why? Seems to be enjoying himself.

I'm very tired, Robert.

I'm very bored.

It's time to wrap this up.

I was very kind of you to walk me back to the college. Not at all. That wine

wonderful. Always a highlight of these things.

I'm afraid I overindulged.

Isn't that what good wine's for?

No grapple for racists! No grapple for racists! This isn't over yet,

Yelland. Who said that?

Where are you?

No grapple for racists! No grapple for racists! No grapple for racists! No

grapple for racists! No grapple for racists!

Ta -da!

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

Hello.

Jeffrey meets us in the college bar after a talk.

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.

We're nearly there.

I need to sleep.

You shall.

You shall.

Oh, there's people.

Forget them. Forget them.

They're so angry.

They like being angry. It makes them feel important.

Come on. Nearly there.

Watch this.

Easy,

easy.

Okay.

Yellen was furious about that protest and the Q &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.

How was he?

A little worse for wear, but fine.

Thanks for waiting.

Let me walk you home.

I was going to meet some friends for a drink 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

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 sun pain have you had?

Not nearly enough.

Well, how many 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, there's a visiting academic by the name of Professor Paul

Yelland. Post -mortem will confirm, but I suspect the cause of death will be

strangulation.

He was in Oxford 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 in the local paper and thought it might be

interesting. And was it? Not really.

But the speaker deserved to be strangled would be, in my opinion, a harsh

review.

Any sense at this talk that he was anxious?

No, this wasn't suicide. The door was forcing me outside.

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

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 the bruising around his neck suggests he struggled hard to

stay alive.

And look at this.

All 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? Well, you don't need a master's degree in criminology to tell you that

somebody whacks you over the head and nicks your wallet that he's dangerous.

Little more to it than that, sir.

Crackpot theories about why people do bad things were all the rage when I was

cadet. There's no doubt with the twin innovations of suspects having motives

fingerprints. There was no DNA testing when I started. It just had to be bloody

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

It's all Hogan.

That's what they said about the Earth orbiting the Sun.

Well, 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

Shea Lewis?

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

You're aware we have a brilliant new service now called dentistry. Yeah, been

there, done that. Got the blood -stained T -shirt never again.

When was that?

20 years ago.

You haven't had your teeth checked in 20 years? It ain't broke.

It's probably rotting on the inside.

That'll be the tooth fairy appalled.

No, it's the chief super requesting the pleasure of our company and our office

before the...

Too late.

Sir?

Look, it's action, man.

Peterson? Boys?

Uh -huh.

D .I. Peterson and his unit have been tracking local extremists, so he may

valuable information for the investigation.

We've been monitoring the anti -racist group that disrupted Yellen's talk.

Mara Barnett.

Figurehead, old school, hardcore.

And other clichés?

We thought they were pretty harmless until now.

Well, we still don't have anything concrete to pin on them.

Needless to say, the vice -chancellor was on the phone within minutes.

A guest of the university murdered on university premises after giving a talk

where, by all accounts, university staff and students tore him apart.

The PR consequences are obviously horrendous. I phoned the paper. They're

running the headline, lynched!

Well, from what I saw, he wouldn't have required much lynching. You were at his

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

some protection for Professor Yelland during his stay, and I turned it down as

unnecessary. On advice from us.

You see, our intelligence said no one had the slightest interest in targeting

Yelland. 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.

Why are you just sitting there looking at me like dogs being shown a card

Come

on,

answer the phone.

So what did he look like?

We couldn't see much detail from where we were, just his bloated face in the

window.

Will freaked out. I'm not surprised.

Whenever we had dissection and biology, he always had a note from home to excuse

him.

Weird to think you were listening to him just an hour earlier. I'm 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 eat too badly.

What's that supposed to mean?

The hot professor?

Will? To name just two.

Will? Look, Emily will sit the mate from home.

Are you sure that's all he is?

How was your run?

Knackery.

I was worried myself I was being chased by the dead guy and talked to my

personal best.

I thought you were going to start running again, Nina.

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

I used to love it. Yeah, and then I stopped loving it. Same as I stopped

watching skinny doggies run round after a teddy bear on a trolley.

You're going to have a shower now. Can I nip in quickly?

I'll be my guest.

Thanks.

I always wanted to learn how to run.

There's not much to it.

It's like walking, only faster.

Strangler is untied.

An advert for Dress Down Fridays, if ever there was one.

I can confirm cause of death was asphyxiation due to strangulation.

He's two and a half times over the limit when he died.

With the sleeping drug Zolpidem in his system.

Toxicology puts ingestion around 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 it would have

with the alcohol to speed up the conking out process.

The conking out process being? An internationally recognised medical term.

Anne -Marie.

Is that it?

Push your boat out into open water, Robbie. Get rowing.

You wouldn't have anything for a bad... tooth in here, would you? I can take it

out if you like.

Of course, you'd have to be dead first.

Too late.

Is this...

All the evidence from Yellen's room?

Yes, Hodge.

I've got an open envelope here with no letter in it.

That's everything.

Go on, if it's me, I need your massive geek brain to crack a laptop password.

shouldn't be too taxing.

I need to get back to your online poker.

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

Thank you. Bye.

Can I help you?

Inspector Louis, Detective Sergeant Hathaway.

It's a thief, Professor Rand.

This doesn't have to be a problem.

Whichever way we spin it...

The events of last night are potentially 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 association 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 him? I don't know, someone who might have slipped something into his

drink.

There were lots of people milling about. 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.

And he must be joking.

I once walked past her office and I heard her on the phone shouting at him.

who? Professor Yelland.

She sounded furious.

About what?

I don't know.

That 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.

I'm afraid we can't promise anything to the hunter, but... Lillian, 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 necessary to request... Police protection for

Professor Yelland?

An academic from an unknown American university pushing an improbable twist

an old theory.

He's hardly the ace of spades in a pack of hate figures.

Actually, he and I were students here together at the same time. He was a high

-flying postgraduate back then.

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

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

Yelland believed biotechnology could breathe new life into the prediction of

criminal dangerousness.

Letter to the new scientist at best.

I think you're underestimating Yellen's proposition.

Unlike the vociferous crowd outside the lecture building.

Rent -a -moth, 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 Yellen's talk into something of an

event. Robert!

An event?

to maintain the profile of the department within the university and

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 and stir up the locals.

The protector is outside the lecture building.

Oh, that was easy.

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

All white, of course.

Happy to give their self -righteous indignation a bit of an airing once in a

blue moon?

Isn't that right, Robert?

Yeah, darling.

Spot on.

Yellander is well compensated.

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

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, it's just she's very 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 yelling 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 really seemed to shake

up. I thought you should know.

Thank you.

The woman who disrupted his talk?

Myra Barnett.

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 all in all,

it's a general no -thanks.

We're the police.

Please, please.

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

We wanted 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 Yellen was escorted out of the lecture theatre, somebody

this isn't over yet, Yellen.

Did you hear that after you were ejected?

No.

Would you be 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 rather overestimate your significance.

I have no ambition towards significance, Inspector.

The struggle, always, is to stay relevant.

Is that all?

Spare me from armchair lefties and their cheap to say.

What was the call?

Gurdip's made a breakthrough.

Yelland has two email accounts.

One for Paul Yelland, professor of criminology, writing tall and sundry

his work.

And the second?

An email account for a small business he was running.

If you collect figurines or anything of that nature and you can't find the last

piece to complete the set, Yelland's your man.

Was your man, Gurdip.

That sandwich is making me hungry.

Robbie?

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

delicious.

As will be this soup.

Mmm.

So, Yelland had a sideline, sourcing and supplying rare collectibles.

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

the point, he had a substantial amount 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 don't know, what were his parents thinking?

Oh, drinking.

It's part of the bizarre range of ceramic, highly colourful, highly

After they met Yelland and paid for the vase, the O 'Briens became convinced

that it was a fake.

They demanded their money back, Yelland refused, at which point Brian O 'Brien

became abusive and then personally threatened.

Return our money forthwith. Who says forthwith anymore?

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, Yellen.

No idea who sent this?

Not the first one.

A few times I've had calls, but it's just silent on the other end.

Look, I can hear breathing.

The number's withheld.

Well, but 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 violent calls.

she had to say would be to your face and it would be extremely scurrying.

Perhaps we should cool things down for a while. Nina, you're beautiful, clever.

You've fought tooth and nail to be here.

Unlike the privileged majority you consider at their birthright, it's bound

cause some resentment.

This isn't just resentment.

It's racist garbage. No, it's just nonsense, Nina.

Ah.

Who is it?

A criminology professor.

Married.

Nina's moving on, William.

Why don't you?

Oh, you follow up on this old Brian lead.

I suppose I should liaise with Peterson's unit.

What do you think Hobson would see in Peterson?

Who knows?

Yeah, Julie.

Yeah?

OK, so two sets of prints on the outside handle of Yellen's door, one of which

belongs to Professor Anne Rand.

Chimes in with what she said about going to Yellen's room after the talk.

Why have we got Rand on our database?

Drink driving two years ago.

Criminologists heal themselves.

Okay, that's great. Thanks, Julie.

So, as well as Yellen's fingerprint, we've got two unknown sets on the

that were found on his floor, one of which matches the unknown print on the

handle, plus one known print on the envelope belonging to an Adam Petal.

I haven't heard of gloves.

So let's start with Mr Petal 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 -globalization. In fact, if there was

being anti about in the last six years, he was there either 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 Yellen'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 Petal an envelope which we recovered from the

scene.

Do you recognise this envelope, Mr Petal?

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

Can you explain why this envelope, with your fingerprints and Paul Yellen'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 gorilla.

What's your instinct?

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

He's holding on to something.

The complete set of Yellen's business emails, sir. Thanks, Julie. Any more on

the O 'Brien?

No, but the camera footage you've been waiting for is ready in the CCTV room.

Cheers.

I'm still printing the email from Yellen's personal account, sir.

Right, thanks, Julie. Go through them with a flea comb.

Fetch me any fleas.

Yes, sir.

Laura managed to pinpoint the exact time of death and the person responsible.

My answer would be yes to both.

Calling you to let you know that I've managed to get you an emergency

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.

Nina, I just wanted to check you're okay.

Is that your thing, Professor?

Clever inner -city black girl? Who the hell are you, and what the hell are you

doing 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 could 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 into 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, many

academics from around the world.

Nothing like this has ever happened before. You can imagine how shocked we

Thanks. Goodbye.

Thank you.

There's Professor Lipton.

And on.

Okay, rewind.

Dot.

You zoom in on that.

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... It's nothing but a malicious lie designed to slander me and humiliate

you.

Why? God only knows. I mean, maybe the person who sent it is jealous of the

attention you've been receiving. 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.

the other one.

We know that 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.

Yellen 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, Miss Hunter, that your long -lost father was

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 Yellen'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 Yellen to read what he'd done to her in her own words.

We recovered an envelope from Yellen's room as Hunter, but no letter.

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

We believe the killer must have taken it.

There were four sets of fingerprints on the envelope.

Yellen's, yours, and another belonging to a young lad by the name of... Adam

Petal.

You know him?

Yes.

Adam's my brother.

Oh, Adam Petal was holding something back. His sister -in -law.

When you showed him the envelope, he must have assumed that Lillian had put

in Yelland's room and then killed him. The question is, did she?

What did you make of that story about her mother?

I was watching her quite carefully. She seemed genuine.

Why would she deliver the letter, kill Yelland and then take the letter back?

Maybe she wanted him to read it and weep. Emotional revenge. And then her

hubby garrot him. Physical revenge. She takes the letter back because it's

the... Last words of her dead mother?

Leaving the envelope.

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

I didn't tell him anything.

Well, there's nothing to tell.

Come on.

Get me on.

I 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's going to try and persuade you that you can continue to see one another.

I... Look, you can't see him anymore, Miss Clements. 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 very carefully to

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.

Well, I was wondering how long it would take you.

How long have you been telling me to do what, exactly?

Well, I assume that you've been looking at the security film from the porter's

lodge from the night that Yellen was killed.

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

time that I subsequently left.

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

Yes.

Well, I wanted to dig out a couple of papers in the wake of the Yellen

I'm ashamed to say that I...

Dropped off when reading one of them. It's rather alarming to realize that

faculties are showing the first signs of crumbling away.

What papers, may I ask?

They're 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.

I'm reading.

Reading?

A pair of two cities.

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

Yes.

I like to come here to read.

Muffet?

Hi.

Thanks for agreeing to meet so early.

When your text came through at six this morning, I assumed it must have been

from my rancid little stalker.

They almost deleted it without reading it. Anne knows.

What? She received an anonymous letter.

At your house? No, at work.

The same person who's been texting me?

Possibly. God.

Robert, what's happening?

What does she do?

She's 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 anymore, 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 for a while. Nina, please, please.

You're hurting me. I need you. Let go.

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

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

Find someone else to give you the thrill you get from 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, you're fine.

Okay, fine.

Keith Poland?

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

Lauren?

Let's go.

Patricia Hutchison?

Oh, that's me.

Upstairs, first door on your left.

Thank you.

Fred McClintock?

Yes. Hygienist is ready if you just want to pop through.

James.

Good. has found Yellen'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.

And the bids have started to come in, so I bought it outright and arranged to

collect it at nine this morning.

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.

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.

Can't be them.

The arrangement must be here at nine with the vase.

It's nine, and they appear to have a vase at the side of the 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. I need 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, 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 Rossers.

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.

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 out, this isn't over yet, Yellen? 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?

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 Yellen was ripping off a lot of people, that's a lot of potential

killing him. But why is it Lillian's mother's letter?

Sir?

Yes, Julie? I've been going through Yellen's personal emails.

There's a correspondence you might be interested in.

Between him and who?

Professor Anne Rand.

Why didn't you tell us you'd had a private correspondence with Yellen when

were first 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 United 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.

Do 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

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 email seemed to suggest that you had a great deal to gain from Yellen's

death. And now he can no longer obstruct your American ambitions.

It's an interesting theory, but I'm assuming that's all it is or you'd have

already arrested me.

The emails give you motive. The CCTV places you around the crime scene about

time Yellen was killed.

Around, but not in.

Purely circumstantial.

If there is any evidence linking you to Yellen's death, it will eventually be

found. Oh, so this is what? An opportunity to confess and save the

some money?

Yes, if you're guilty.

If guilty.

If. Detective Sargent.

Only two letters, but a very big word.

Laura, before you tell me how very, very busy your dad is too, let me explain.

Half the way he caught me as I was about to go in.

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, that's Nina.

How?

There's a bit of blood in the back of the head.

Professor Lipton was Nina's tutor.

Have a word with him.

Also the university counselling service.

If there's anything we ought to know about there.

Young 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 Yellen case?

She was at that talk and she walked Professor Yellen home from the college

Robert Fraser.

Well, we shouldn't rule out tip for tap by the far right.

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

Something I didn't want to mention in front of them.

A blow to Nina's head would have resulted in a massive external

yet... There was very little blood with the body. A very small amount of

coagulant. She wasn't attacked there.

No.

Take a seat, Emma.

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.

At least he has a friend like you to support him.

It'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 Clements having an affair with?

Robert Fraser.

I'm in.

Shocking events, Detective Sargent.

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 behavior.

As, of course, of you, from your side of the fence.

But it is to make somebody cross that line when others don't.

It's not always clear.

I find I can't better Jean Renoir's observation that the real hell of life

that everyone has his reasons.

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

she say anything to you in the days leading up to her death that would shine

light on that?

She did call and asked to come and see me.

just hours before she died.

She confessed that she was having an affair with Robert Fraser and that his

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, too.

Exactly. 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 directly 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?

I shouldn't rule out a racist assault.

Nor a link to Yellen's death.

No.

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

Okay, bring them all in.

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

We've just taken a report of a disturbance at Robert Fraser's

Come out, you merry bastard! Please, come quick, come quick.

Hurry up, hurry up!

You're not going to come out.

I'm just going to have to come in.

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

Robert doesn't do affairs.

He does periodic infatuation with girls too starstruck to see the wood for the

trees.

So you helped Nina Clements 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 to

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

be put through this indignity by a man she stood by and nurtured for 20 years.

You repeatedly insist that you're an unlikely suspect because of your

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 the table, shake you by the

lapels and demand that you stop being so ridiculous.

But look, despite my very strong motive, I'm perfectly 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... I don't mind it.

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

Did you?

I... loved her.

I can't tell you how many murderers I've heard saying exactly the same words in

exactly the same way.

And you know what?

They all meant it.

I didn't kill her.

When you asked Nina Clemens to break off 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 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

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 Yellen 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.

Well, try, because you should.

No, she wouldn't. Perhaps the idea of fitting you up for Nina's murder

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 think I've ever met.

What about the boy, Will?

According to Emily, he carried a torch for Nina when they were at school

together.

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

If Will can't have her, nobody can.

Apparently he hasn't said a word in a holding cell, he just stares at the

in silence.

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

What if she confessed to the lesser crimes so as to distract us from her

one? They are smart kids.

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

Surprise her. Push her harder.

Excuse me.

Dr Holton.

Laura! Robbie, I need you to come and see me.

Now.

Hello, Emily.

May I?

Please.

Thanks, Laura.

No problem.

Speak later.

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.

What about the thin, mustard -coloured fibres? From the head wound.

Cotton from bookcloth, apparently.

Bookcloth? No, not used so much these days due to cost, but in the past,

textbooks... Volumes of reference, compendia, etc.

were all covered with bookcloth.

Right.

Sorry.

I've 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, anonymous 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 that

you could have will to yourself.

You think I killed her?

possibly think that? Both you and Will have strong motives.

Will loved her. That was the whole problem.

Did he love her too much?

Oh.

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 will return them to her.

Yeah? Where are you?

Just finished up with Emily. She's pretty shaken up. I think she's told us

everything. Either that or she's a damn good actress to you.

I'm on my way to catch up with the Sockos in that woodland where they found

Nina's body.

I reckon she must have been dumped there, rolled up in a carpet or a rug of

kind. I'm going to drop off some of Nina's tutor's old papers, see if he can

remember anything else of you, 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.

Miss Hunter.

Detective Inspector Hathaway.

Still just a sergeant.

And I'm returning a couple of Professor Lipton's papers in a book that was in

Nina Clements' possession when... Very good of you.

Come in.

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

Thanks.

Sir! Sir!

Sir?

James?

We found the rug.

About a mile away from where the body was.

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

Yeah, how did you know that?

Because I'm dead in Lipton's front room looking down at where... Sergeant.

Let me take those.

I'll come through.

Wait a minute.

Tom, you!

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

Yes. And a book. I gave them to, um... Lillian.

Yes.

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

administrative remit to include me.

Are you married?

Oh, well, then, as a fellow bachelor, you'll understand.

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

Wait a minute.

Unfunter.

And duster.

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

Andrew, Professor Lipton's a confirmed bachelor.

I think he stopped noticing the gathering dust years ago.

Sergeant Hathaway's just been signed.

I'll let them know you're here.

Thanks.

Inspector Lewis.

Well, 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' 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.

This coloured patch and its colour matches these fibres, which I've just

on your floor.

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

mustard cloth.

And I have so many books, ipso facto.

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

Where's the methane volume, Professor?

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

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

What has Lillian 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 it for yourself?

I do not pray upon undergraduates for sex.

So, again, what has Lillian been clearing up?

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

leave her out of it.

She is entirely innocent.

Well, not entirely, surely.

She served yellow wine at the reception.

Ample opportunity to slip him a sedative.

We've got her on CCTV going into the college later that night. And here she

Two days after Nina Clements is murdered, giving your place a good old

Andrew, what's going on?

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

Now, coincidentally, Lillian's mother was studying at Oxford at the same time.

Did you know her, too?

I did.

So... Lillian knows all about you and her mother and Yellen, doesn't she?

Lillian knows nothing. If she knew that you were the undergraduate in love with

her mother at the time that Paul Yellen 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 any different if he'd fought harder? The

universe would have been different. But she chose Yelland.

He stole her.

He stole her and he destroyed her.

Well, I heard about the suicide.

I tracked him down.

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

So the article appears that you gave me to show Anne.

It 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 Lillian had left earlier that night, 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.

I should have remained in the past tense. We were all going direct the

way, whether 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.

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.

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 grabbed her coat, I pulled her back.

She stepped 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, it 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 would have taken care of you?

Oh, my darling girl.

I couldn't let that happen. But despite your best efforts, it will.

Until 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 with 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 which you later rely on in court.

Anything you do say may be given in evidence.

Please.

Professor.

It's evidence now.

Hear that?

What? A flapping of chickens coming home to roost.

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

Now he's going to die in prison.

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

Poor Lillian's going to end up serving that life sentence.

Ah, 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 a specialty. 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 celly in a sweaty pub.

Got a book to finish.

You learn 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.
