(dramatic violin music) How do I look?

-Uncomfortable.

-Hm.

Beware all enterprise that requires new clothes.

(chuckles) Wasn't that Dr. Goldberg?

And now she is going to think I am getting married.

(upbeat violin music) How was it?

Yeah, it was good.

Fancy another coffee?

Why are we here?

It's not your... No, no, no.

Clean bill of health.

-Oh, good.

I was hoping I might be able to twist your arm.

Police fundraiser?

We'll just do a couple of tunes, it'll be nice.

Dad, we've been over this so many times, alright, I've swapped shifts.

It's done.

Oi!

Dan, I spoke to your boss.

If you don't want to say a few words about Lisa you don't... Dad, just drop it, alright?

(car hoots) (thump, people scream) Oh my God!

(suspenseful music) Okay, call an ambulance.

My phone's on the table.

-Okay.

-Hey, hey, hey...stay back.

-He walked right in front of me.

-Yeah, yeah, yeah, I know, I know, I saw it.

Don't do that, don't do that.

Keep your eyes open.

That's it, look at me.

You're gonna be okay, alright?

I'm a police officer.

Just look at me.

LISA: Dan.

(sorrowful music) I pushed him.

I...

I killed him.

(siren wailing) What?

Who, who, who did you kill?

Who did you kill?

No, no, no, come on, don't do that.

Don't do that, don't do that.

Come on, look at me.

Look at me, look at me.

Don't do that, come on.

(theme music) (doorbell rings) I am not about to be betrothed.

Contrary to what you think you may have witnessed in the window of the gentleman's outfitters, uh, I am not getting married.

Your aunt?

Yes, I...I just heard.

Yes, exactly.

Uh... well, um...

I must go.

Um...

I assume you're here to deliver my invitation... to the wedding.

Oh, uh... No.

Oh, right.

(laughs) Hmm.

Give your aunt my best.

(door closes) Yeah, good.

Oh, Dan, I got some details on that accident that you witnessed.

The driver's record was clean.

There was nothing in his system to suggest impaired judgment.

The deceased was Jay Morgan, a second-year Land Economy student at Cambridge.

DC Highsmith?

I'm okay, Ma'am, I'm just waiting for DS Winters.

Well, he's right here.

Come in.

Drew a blank.

On what?

I, uh, I asked Chloe to check out hospitals, mortuaries, find out if they had any admissions that, um... That there might be signs they were a victim of an, uh, an assault.

Jay Morgan's last words were, I killed him.

Yeah, we've got a murder to investigate with no body.

No, we don't.

If we get a body, then we investigate.

Our stats are just picking up.

Let's not invent work for ourselves, please.

-Sure.

-Okay.

(light music) (sheet swishes) Cause of death, intracerebral hemorrhage.

From the car or the fall?

You were there.

It could have been either.

Most of the samples haven't come back from the lab yet.

(whooshing) The way he was moving, um... (dark music) he seemed absolutely smashed.

MEDICAL EXAMINER: Blood alcohol level was just over the legal limit.

So, he shouldn't have been unsteady on his feet.

Unless he had a very low tolerance.

One sample, which we did get back, indicated raised diuretic levels.

-Is that significant?

-Could be.

Diuretics are a way of masking anabolic steroids.

Professor, I found this in your recycling bin.

I had no idea your duties included scavenging.

It's an invitation to the Science Innovation lecture.

Lyndon Collins is giving a talk on gene editing.

Which is why it was in the bin.

What he's proposing could eradicate violent crime, put you out of a job.

Tell him.

The Dean of Life Sciences thinks Collins has a product that, once approved, would benefit the university.

And this concerns Miss Snares...why?

I believe she's stepping out with Mr. Collins.

-Ah.

-Impressive guest list.

Experts in neurology, psychology, social sciences.

Oh, Dr. Goldberg.

Oh, oh, when is it?

Two o'clock, Wednesday.

Drinks to follow.

Hm.

(dog barking distantly) (knocking on door) DS WINTERS: I'm so sorry for your loss.

So, Jay rowed for his college?

Proudest day of my life when he got accepted to Cambridge.

Such a relief.

Why was it a relief?

(sighs) This neighborhood.

Nothing to do.

-Thanks.

Kids get drawn into things.

What sort of things?

Oh... Jay used to drink 'cause he was bored.

Would you say he had a problem?

No, once he got fit, he rarely touched the stuff.

There's a lot of pressure on athletes to bulk up.

Do you know if Jay took anything to help with his physique?

No.

My Jay was totally against all that.

How'd he fit in?

At university?

(exhales) It was hard.

He got a sports scholarship in the first year, but... this year was... financially hard.

And, um... was he close to anyone on the rowing team?

He didn't talk to me about university.

He was there, and... (melancholic music) I was here, and... there was a river between us.

Sorry.

(sobs) -That's alright, don't... -(ironic chuckle) (oars splashing) (dramatic music) COACH: Come on!

Long, fluid strokes!

Long, fluid strokes.

Come on, yes, yes.

DS Winters.

I called your office.

-Nobody told me.

-It's about Jay Morgan.

-I'm busy.

-Do you know about Jay?

-Of course, I know.

I've lost half my team.

This is my priority.

(oars splashing) Did Jay have a problem with alcohol?

What about steroid use, is that an issue at this level?

A day like today, and you come here with rubbish like that.

I'm trying to find out why a young man walked in front of a car.

Well, let me know when you do.

(phone rings) Come on.

Bring it in.

Alright, come on.

-Winters.

DC HIGHSMITH: Tina Northam.

Jay Morgan's rowing instructor.

Yeah, I've just been talking to her.

She was one of the coaches on the US Great Lakes rowing team.

Quit two years ago after she was accused of encouraging some of the team to use performance-enhancing drugs.

Are you gonna bring her in?

I think I'd better run it past DCI Goswami.

Okay.

See you later.

Alright.

Professor.

Two things you should know before you sit in judgment.

Lyndon Collins is developing a product that will be worth millions.

He has refused to take part in any future revenue streams.

Why?

Because he's doing it to honor his brother who was killed following an unprovoked violent assault.

Why are you telling me this?

Lyndon would like to deliver a lecture to your students.

Thus, gaining him credence with the regulatory agency.

The product has already been approved in other countries.

Mr. Collins' reputation precedes him somewhat.

That was 10 years ago.

People change.

-Do they?

The least you could do is listen to what he has to say.

I intend to.

Wednesday at two.

Hmm.

He's fine, by the way... my father, if you're asking.

I'm sorry?

Despite you persuading your aunt not to marry him.

I did nothing of the sort.

(upbeat music) You can tell your aunt I've never seen him happier.

The new manager at his residence has relaxed the rule on dogs.

He's got himself a dandy Dinmont.

I suggested he call it Zelda.

(knocking on door) Ma'am.

Hm-mm.

Oh, never a good sign when you start with Ma'am.

Look, I know you said to drop the Jay Morgan thing, but the preliminary path report said that his diuretic levels were raised.

And why is that significant?

He was on the university rowing team.

And his coach, Tina Northam, she's... she's got a reputation for giving drugs to her teams.

Where's all this coming from?

Oh, you've still got DC Highsmith roped in.

(door closes) In the US, Tina Northam claimed she was using natural products to enhance performance.

But the other coaches said that she was using masking agents.

-Diuretics.

Masking for what?

BOTH: Steroids.

And you think that's why Jay Morgan walked out in front of a car?

Oh, I don't know, but... what I do know is, steroids...

If he was on them.

If he was on them, yes.

Steroids can cause aggression, mood swings, paranoia.

And you're gonna tell me connects to this notion that he thinks he killed someone.

Yes.

Has anyone been reported missing in the last 48 hours?

Not that we're aware of.

Okay, there is no case.

Chloe, I suggest you start focusing on your exam.

It's your last chance.

Dan, I know you don't want to let this go, but there's nothing to investigate.

I don't know what you mean, I don't want to let this go?

A young person died in your arms, Dan.

Just after being hit by a car.

(dramatic music) I know, but what hap... what happened has got nothing to do... Jay Morgan said, "I killed him."

Alright?

If you're asking me to ignore a dying man's last words, maybe I'm in the wrong job.

(door slams) (wind whistling) Good workout.

-Have you got a minute?

-No.

You told my colleague you lost half your team.

Apart from Jay Morgan, who else did you lose?

They're students, they come and go.

Yeah, but you're very driven.

Got your own methods.

The Americans said you gave your team masking agents.

(suspenseful music) I just need the answer to one question.

Who quit the team?

That was a long lunch.

Where have you been?

(clears throat) I, um... Chloe?

I went to speak to Tina Northam.

Shall we take this in here, considering it concerns you?

Whose idea was it for Chloe to see Tina Northam?

BOTH: Mine.

One of Tina Northam's rowers didn't show up for practice today.

-Has he been reported missing?

-No.

Get back to me when he has, yeah?

(door slams) She's only trying to help, it's not her fault.

I know it wasn't her fault.

Of course she's trying to help.

I'm trying to help, the Professor's trying to help, your dad's trying to help.

Everybody's trying to help, Dan, except you.

(dramatic music) (mouths) I'm sorry.

(soft Italian singing) (music increases in tempo) CHLOE: Sorry.

(door closes with echo) (melancholic music) Jasper.

I need to see you.

I raised my voice at my commanding officer.

You don't do that.

Is that why you're here?

A young guy got...hit by a car.

I tried to save him but, um... he died.

I heard, um...

I heard someone call my name.

In here.

In moments of high stress, auditory hallucinations are not uncommon.

But what it tells me is there may be an underlying cause.

Thought I should be over that by now.

Should you?

Don't we just gradually learn to live with tragedy?

Why is it so hard?

(soft music) Life's complicated.

Contradictory.

It's often absurd.

And sometimes... in order to survive, we just need to accept that.

I've made such a mess.

I can't face Wilfred.

Perhaps you are experiencing first-night nerves.

Adelaide's painting, the one that was damaged, Wilfred had it restored.

He's my sister's loyal companion.

And he will remain so once he is married.

Ever since I told Adelaide that Wilfred had proposed, she hasn't returned a single call.

I have had the same problem.

How could I even think of coming between them?

How could I have been so selfish?

That is a very good question.

Why were you so selfish?

I was selfish because I was in love.

Is that not reason enough?

No.

No, it's not.

Yes, it is.

Love is enough.

How'd it go?

I guess we'll find out tomorrow.

Did you answer all the questions this time?

Nope.

How come?

Chloe?

I was late.

Just got this in from the path lab.

Jay Morgan... he showed low levels of protein C and S. Now, these proteins aid blood clotting, and he died from a cranial bleed.

Which had nothing to do with diuretics.

Nothing to do with steroids.

Well, don't get ahead of yourself, 'cause based on what you told me, I requested some more information.

These steroids can cause blood clots.

So, to counteract that, they add anticoagulants.

Bang on.

So, Tina Northam's still in the frame?

(suspenseful music) You got your case.

Go crack it.

Tina, our information indicates a steroid may have been responsible for Jay Morgan's death.

I never gave anyone I trained anything that could harm them.

Natural supplements, that was all.

Okay.

What was in these natural supplements?

Creatine, hibiscus, caraway seeds.

Hibiscus and caraway seeds are diuretics.

Well done, queen of the internet.

Used to mask the use of steroids.

Hibiscus and caraway boost energy.

Did you get that far?

You told us you lost half your team.

Now, the lads I spoke to at the river, they told me that Alex Healey was the team captain.

-Alex quit.

-Why?

Get a second job.

His student loan wasn't enough to survive on.

Were Jay and Alex friends?

I don't know.

They had a huge row when Alex said he was quitting.

DS WINTERS: It all slots together.

Masking agent, steroids, aggression, Alex quits, Jay attacks him.

Mm, kills him.

Yeah, gets drunk, hit by a car, confesses.

Is this it?

-No, it's that one down there.

Oh.

You do realize that if Alex is here, that's your theory blown.

DS WINTERS: Excuse me.

Sorry, we're looking for Alex Healey?

He's not in his room.

DC HIGHSMITH: Do you know where he is?

No.

When d'you last see him?

Uh, a couple of days ago.

Why?

-Was he with anyone?

Yeah, a friend came by carrying some beers.

And then I saw the same guy by the river, like an hour later.

Seemed pretty wasted.

Thank you.

(sinister music) (crickets chirping) I'll do the river.

Okay.

(tense music) DS Winters.

Dan!

Hi, uh, this is DS Winters... (birds singing) (students chattering) Good afternoon.

I am Lyndon Collins.

For the past four years, I've been involved in the development of a product called... Topranitzol.

Medication has been used to modify gene expression in the treatment of substance abuse.

The medication I am here to talk about today will use the same methods to prevent individual acts of violence.

(dramatic music) You see, the brains of violent criminals show striking anomalies.

In most cases, parts of the amygdala are underdeveloped.

Through gene editing, we can change this.

Alex Healey, 21-years-old, no marks, no bruises to the face, torso... What about his arms?

Minor bruising on both forearms.

Jay Morgan said he killed someone, said he pushed him.

Someone pushes me, I fall over, that's where I land.

Bruising like this would never cause the death of a young, healthy man.

But because of the Jay Morgan case, I fast-tracked the protein test.

Low levels of protein C and S?

Unusually low.

Much lower than with Jay Morgan.

What's that mean?

With values this low, a minor internal bleed could cause someone to go into shock and die.

Especially if they had a pre-existing condition.

Alex Healey had thrombocytopenia, a low blood platelet count.

Not usually life-threatening.

Unless someone gave him something that made it worse.

Exactly.

Can we hold Tina Northam for another 24 hours?

DSI GOSWAMI: Do we have the grounds?

Yeah, it looks like Jay Morgan and Alex Healey were having a drink, right.

Jay's pushed Alex, he's fallen, gone into shock and died.

And what's this got to do with Tina Northam?

Uh, alcohol had an unusually potent effect on Jay, and, um, Alex has died from bruises he normally wouldn't have even noticed.

And?

They died because their blood had been thinned to an abnormal degree.

I think Tina Northam gave them steroids laced with anticoagulants.

(suspenseful music) (people chattering) No, thank you.

I've just spoken to the Chancellor.

Two of our students have been found dead.

She's wondering what you could find out from the police.

Mm.

I treated those young men like I would my own son.

One of those young men died in my arms.

Everything I did was to help them become the men they could be.

Two of them will never achieve that now, will they?

So, how did blood thinners get in their system?

By the time you admit you've got this wrong, my career will be over.

Jay Morgan died thinking he killed his best friend, and you're worried about your career?

(people chattering) I, I, I really think a further lecture, properly publicized, will help to sway public opinion and expedite approval for the product.

Mr. Collins thinks a talk delivered to your students would be beneficial.

Beneficial to whom?

The problem with this product, of course, is that one cannot prove a negative.

Unless instances of violent crime show a marked decrease.

The same could be achieved by funding community projects.

I spoke with DS Winters, two Land Economy students, Jay Morgan and Alex Healey.

Oh.

Two of our students found dead.

Do the police know what happened?

They have their theories.

They are waiting for the full forensic reports.

MISS SNARES: Oh no, that's awful.

Yes, it is.

But could we discuss the possibility of another lecture?

Properly moderated, I am open to the idea of a further talk.

Moderated by whom?

By myself, perhaps.

In order to undertake such a role, I would, of course, need sight of your research materials.

We could do that now.

Er, I'm afraid that doesn't work for me.

First thing in the morning, come to the lab?

I look forward to it.

Um... don't you have a wedding to attend?

Oh.

Yes.

So, he came and knocked on your door to tell you he wasn't getting married?

Yeah.

Doesn't that seem rather telling?

No.

I think it's rather him.

You signed him off?

Yes.

How did you feel?

Felt rather odd.

He made some remark, which I took to be about his drum therapist, and left.

-Drum therapist?

-Yes.

You said he didn't have a sense of humor.

He doesn't.

He never smiles.

Well, he did smile... on that occasion.

(soft music) (laughs) The smile you're mirroring.

Helena, it would seem that you have genuine feelings for this man.

No.

No, I...I, uh... no, I, I...I refuse to allow it.

-Why?

Because I have a professional reputation to think of.

Is that all?

No.

There's also, and I can't emphasize this enough, the ick factor.

The idea of a therapist and a client in a relationship.

He's no longer a client.

Former client.

So, embarrassment and professional probity is preventing you from doing something that could bring you happiness.

(sighs) (soft music continues) (tuts) I can't do it.

And I'm not going to.

(clears throat) -Dan?

-Yeah?

Young lad there.

On the rowing team.

Tina Northam spoke to him about taking steroids.

Really?

(suspenseful music) He said he'll make a statement.

We've got her.

(exhales loudly) (bell tolls) (upbeat music) (taxi engine rumbles) (taxi door opens) (door closes) I thought Cambridge was supposed to be safe.

Your car?

Two laptops, my phone, slides, half a dozen USBs all gone.

My life's work stolen.

Hm.

Is there any material at the lab that I could look at?

It was all in there.

Everything.

Hm.

Have you reported it to the police?

No, not yet.

(car door closes) In that case, allow me to give you a lift.

I insist.

(taxi engine starts) (background chatter) Professor, you wanted to see us?

A colleague of mine, Professor Lyndon Collins, has been trialing a new drug called Topranitzol.

Collins has been testing the drug on student volunteers.

I believe Jay and Alex were amongst them, and it proved fatal to them.

This Topranitzol has been sold in... nine countries.

On prescription, with strict warnings.

What are the warnings?

That it must not be taken with alcohol and contains anticoagulants.

Jay was drunk, and Alex Healey had a low blood platelet count.

Okay, let's get him in.

PROFESSOR T: He is already here.

I thought it best not to waste time.

It is an important day.

(chuckles) This is preposterous.

The back window of my car was smashed.

You used Jay Morgan and Alex Healey as subjects for your experiments.

I used many students.

(dramatic music) I would check my records, but as... DC HIGHSMITH: Those have been stolen.

It's convenient.

(DS Winters clears his throat) Alex Healey... he suffered from a, uh, from a... from a...from a condition that slows clotting, you know, so he should, uh... he should never have been a part of the trial.

And, uh, Jay Morgan was... was, um... was mowed down by a car.

(loud hooting) (brakes squealing) Oh, God.

(panicked breathing) Don't do that.

Don't do that.

Come on, look at me.

Look at me, look at me.

Don't do that.

Come on.

(dramatic music) (panicked breathing) Dan.

(clattering) (door closes) Interview terminated.

(distant siren wailing) Let me take over the interview.

No, no.

I've got to do this.

Maybe this has just got too much.

If I don't go back in there, I might as well give up.

Okay.

Alright.

You need to go.

You have obligations of your own.

The fundraiser.

No, I'm not doing it.

Collins, he's too confident.

It's like... it's like we've got nothing.

When he heard that Jay and Alex were dead, I could detect in his reaction echoes of guilt, shame, possibly even remorse.

(dramatic music) Lyndon Collins knows the impact of a sudden, unexpected tragedy.

(door opens) My solicitor is not here.

That's okay, um...

I'm here to...to chat.

Uh, informally, um...

I'll sit here.

(chair scrapes) A year ago, um...

I lost someone I was close to.

And I'm telling you this because...

I know what happened to your brother.

Pressure on you... to fill that void.

When my colleague, um... colleague... she was the woman I was gonna marry, I can't even say her name.

(voice breaks) When she was killed, I tried to do the job the way she did, but...

I put people in danger.

I spoke to Jay Morgan's mother, she sacrificed... so much... just to give him the chance to go to university.

You know, she... she needs to know what happened.

Alex Healey's parents too, you know, they... they need closure.

We all need closure.

Jay and Alex were the same age as your brother.

(melancholic music) 20.

The button's right there, if you choose to go on the record.

You paid Jay and Alex, as soon as we connect their bank accounts to yours, it's over.

I'm not a bad person.

I know.

Say her name.

Lisa.

(sobs) I wanted to make the world a safer place.

(dramatic music) Full confession.

You know, Lisa would have been really impressed.

Maybe.

(sniffs) Ah, yeah.

Is that your result?

Oh, mate, I'm sorry.

(light music) (sobbing) Dan, I passed.

-You passed?

-Yeah.

(laughs) Oh, hey.

Oh.

Well done.

Thank you.

It's alright.

(laughs, sobs) For once, I seem to lack the appropriate words.

What does one say to a colleague whose paramour has been charged with murder?

(scoffs) You know what Collins said to me?

He told me his work comes first.

I told him this dame plays second fiddle to no one.

He was history long before the unpleasantness.

(applause) (car toots) (joyous music) -Dan.

-Hi, Dad.

Oh, I'm glad you decided to come.

I solemnly declare that I know of no lawful impediment why I, Zelda Radclyffe, may not be joined in matrimony to Wilfred James Hamilton.

Would you like now to exchange rings.

And if you wish, you may kiss.

(applause) (cheering) Ooh.

Aunt, I will see you at the reception.

Where are you going?

I cannot believe I'm doing this.

Try not to crash.

WILFRED: Uh, Mrs. Hamilton, the bouquet.

Uh, sorry, say that again?

-The bouquet.

-Not that bit.

-Mrs. Hamilton.

-Mm.

Oh wow.

(applause) As many of you know, a year ago we lost one of our most valued, respected, and loved colleagues in the line of duty.

And so, I'd like to dedicate this event to the memory of Detective Inspector Lisa Donckers.

-To Lisa.

-ALL: To Lisa.

And now the band will play one of Lisa's favorite tunes.

(applause) I think maybe you... you should do this.

Would you take one of your students' exams for them?

-No.

-You've got this.

(dramatic music) Mate, feel it.

(somber music) (band performs) (cheering & applause) (light music) (guests chattering) Oh, he's here.

Yes.

Jasper.

Your aunt was wondering if you'd care to make the inaugural speech.

Hm.

Ladies and... (microphone feedback) ah, the traditional burst of feedback.

Ladies and gentlemen, as the first person to speak, I believe it behooves me to welcome you all.

Of course, an occasion such as this could not be complete unless blessed by one unique woman.

Surprise!

(laughs) Zelda, the only reason I exposed my plants to the dubious ministrations of Wilfred is because I knew you'd be there.

I was playing Cupid.

(laughter) I first took notice of Zelda when I was six.

I was upset about something, and this little thing sat down next to me and took my hand.

Since that day, I've always felt Zelda's hand in mine.

Growing up, I was amazed by her sense of adventure, and the talent that took her around the world.

She showed me a different way to live, which is why I'm here.

And Wilfred, you watering my plants is why you're there.

To my beloved sister and my dearest, dearest friend all my love.

From a place I've always wanted to visit... Adelaide.

(laughter, applause) Chin-chin.

Ladies and gentlemen, would you please charge your glasses as I propose the first toast to Zelda and Wilfred.

Zelda and Wilfred.

(applause) Thank you so much.

Thank you.

(dance music) You received my invitation.

Mm.

(romantic music) Are you gonna ask me to dance?

-Dr. Goldberg... -Helena, I think, don't you?

Helena, may I have the pleasure?

Oh, goodness.

How do you feel?

I feel rather wonderful.

(romantic Italian song)
