Excuse me. Hello?

Hi.

- A bit tied up there, mate? - Yeah. Last night was my stag do.

- Looks like it was a good time. - I mean, the golf was fun.

OK.

Let's see.

All right, this, uh... this is gonna hurt a little bit.

I'll be fine.

Actually, I think I'll stay right here.

It's quite a nice view.

You know, this works great for my beauty therapist.

You're just gonna have to handle it.

- Kia ora! - Hey.

- Sorry, a bit of a hairy situation. - Oh, speaking of.

Margo Booth,

promising young scientist;

was the recipient of a prestigious research scholarship;

on the way to the top of her field.

Six weeks ago, she died in the campus chemical science lab.

What a waste. What happened?

Margo was working alone on a Saturday morning

and accidentally started a fire with an unattended Bunsen burner.

She was getting dry ice from the store room at the time.

The sprinklers went off, water plus dry ice equals deadly.

Margo died from asphyxiation, excessive inhalation of carbon dioxide.

Well, that is really awful but seems like an accident.

Yeah, the WorkSafe investigation ruled that too.

But Margo's best friend, Keri-Anne Harker,

is convinced something isn't quite right.

You don't usually reopen cases based on the word of a best friend.

True. Margo's brilliant, apparently.

How does someone like her make a mistake like that?

So what do you think happened?

I can't really have an opinion.

Can't have an opinion or don't have an opinion?

Margo's supervisors are Professor Duncan Lovell...

and...

- ...Professor Virginia Henare. - Uh-huh.

Sister?

No, cousin. No, c, second cousin. Cousin-in-law!

Actually, Virginia is...

my wife.

No.

- Stop. Since when were you married? - It's a long story.

Well, I have quite a lot of questions, actually, Harry,

and only one or two of them are about the case,

but let's just start with why are we here?

Do you want me to prove that Mrs Henare didn't do it?

She definitely didn't do it.

- She said that? - I don't know.

I haven't spoken to her, not for a few years.

Access card to the chemistry building. Just take a look for me?

A once-over to make sure that nothing nuts is going on

before I send a team bowling in?

- Sure. - Really?

What are friends for, Harry?

And you can answer all my other questions...

later.

Harry has a wife?! Who is she?

How did they meet? When did they meet?

How long have they been married? What is she like?

Can you just calm the farm so we can find out?

Here, Margo Booth, brilliant PhD student.

But what has this got to do with Harry's missus?

OK, OK, farm calmed.

So, one morning, Margo's working with carbon dioxide.

She leaves a Bunsen burner unattended.

Before you know it, whoosh, fire, sprinklers, dry ice...

A fatal combination. Poor Margo.

Good morning, lab rats.

I've been using gas chromatography mass spectrometry

to precisely identify and quantify compounds within the sample.

GC-MS is amazing.

It's so specific. It can identify contaminants

like toxins and additives.

But right now, you might be going,

'Margo, what on earth are you talking about?'

- Yeah, a little bit, yeah. - I'm thinking food.

Oh, I'm OK. I just ate.

- It's all about what we eat. - Oh, right.

And what we don't want to eat,

like microplastics. Ew, gross.

And in here, I have 20 everyday foods I've examined using GC-MS.

I mean, clearly a bright kid, right?

Yeah, too bright to leave a fire unattended in a lab.

Exactly.

OK, I feel that I've been very patient, Alexa.

Are we at the bit about Harry's surprise wife yet?

Almost.

Here, Professor Virginia Henare.

Whoa.

- Wait, she was Margo's supervisor? - Yeah, one of them.

You're thinking Margo wasn't alone in the lab that morning.

And I'm not the only one.

Come along.

Oh, amazing. You absolutely look like private detectives.

We're not exactly that. I'm Madison, and this is Alexa.

Keri-Anne, Margo's best friend.

Please, come in.

I'm so glad the police took me seriously

because Margo didn't make mistakes.

I mean, how could a person with such an OCD

room ignore protocol she'd followed hundreds of times?

Oh, this is where Margo did her science videos.

That's right. I was so stressed about her death.

- Stressed or sad? - Sad.

It was Margo who was stressed.

All she did the month before she died was work, work, work.

That Professor Virginia really cracked the whip.

Are you saying Margo was unhappy about it?

I thought she loved her work.

Unless it was an act in the videos?

No. She was a very genuine person.

Losing her has impacted my studies so much.

Thankfully, I have my creative writing as an outlet.

I'm an English PhD student,

'Head Over Gothic Heels: An Examination of the Interplay

Between Fashion Choice and Emotional Despair

'in Gothic Romantic Literature 1800 to 1850.'

Sounds very specific. Um, tell me more about it.

Well, goth subcultures are born from feelings of otherness.

It's all about diversity, open-mindedness, freedom of expression.

Now, as much as we'd love to hear more,

we've got a case to investigate.

And I am so grateful.

Not knowing what really happened to my best friend is so... disruptive.

You know?

Someone is not sold on Keri-Anne.

Well, if Harry asked us to look into things

just because Keri-Anne thinks we should,

then we wouldn't be looking into them.

But you want to meet Mrs Henare.

- Can I come too? - No. I got another job for you.

Keri-Anne reckons that the professor worked Margo too hard.

I want you to find out if that was a common experience.

Fine. But I want every detail, OK? Every detail.

I love a woman who can handle fire.

Professor Henare, I'm Alexa Crowe.

- I'm a friend of Harry's. - Oh.

Well, that's a name from the past.

Well, sort of. I mean, you do still have a surname.

This is true. So what can I do for you, friend of... Harry's?

Well, I'm looking into the recent death of your student, Margo Booth.

Harry sent you to ask about Margo.

Why didn't he just pick up the phone?

Uh, conflict of interest.

Margo didn't follow safety procedures.

Well, you must have wondered about that. I mean,

Margo was a diligent student,

a star in the making, by all accounts.

Which is why it's a tragedy.

Where is that boy with my sushi? Is he catching the tuna himself?

Oh, hello. I'm Professor Lovell. And you are?

- Alexa Crowe. How do you do? - She's a police detective, Duncan.

Oh, I didn't say that. I'm just a friend of the police.

Apparently, poor Margo's accident is no longer an accident.

Oh gosh. WorkSafe already did a thorough investigation.

Yes, I'm aware of that.

I mean, we had questions ourselves.

Why would someone like Margo break crucial safety rules?

Well, I put it down to unbridled enthusiasm.

Margo threw herself into her research,

which was to be admired, of course.

But she could be impatient, coming in here on a Saturday morning alone.

So it's... as if she was on the verge of a breakthrough

and could not wait for a safety buddy.

A breakthrough? Well, we'll never know, will we?

Look, I'm in the middle of something now,

but we will help you in any way that we can.

Of course we will. You just give us some notice, and we're all yours.

Oh.

And please pass on my regards to Harry.

Riding solo today, huh?

Yeah, Alexa's catching up with Harry's wife.

- Wait. His what? - So you didn't know this either?

- No! - Oh!

Uh, why weren't we invited to his wedding?

No, this isn't recent.

He's had a wife this whole time.

- Nah. - Yeah!

Oh, I got to take this.

Madison speaking.

Thank you so much for calling back.

When was Professor Henare your supervisor?

I wonder how fast a dry ice cloud will grow when water is at it.

I'm pretty sure you can find that info online.

Oh, yes, yes, I know,

but I want to see how quickly things happen in the lab

and why Margo didn't have time to escape.

Remember all of those dry ice deaths we found online,

including the man who used it to store ice cream?

It leaked into his kitchen, and see you later.

Hello, that's why I'm outside.

Alexa!

Oops.

So, the answer is real quick.

You could just believe what people say

rather than proving everything yourself.

We'd never solve anything if we just believe what people say.

So, what's the goss on the wife? What was she like?

Fine.

What do her former students say?

That she's brilliant but a little cold.

They all really love the other supervisor, Duncan, though.

He's the friendly, fun, if a bit absent-minded professor.

So is that code for 'not very good at his job'?

- Kia ora. - Hey.

Hello.

Are we going inside?

Oh, it'll be clear in about 45 minutes.

Which should be enough time to get the full story on your love life.

Have you received the access card records from campus security?

- Did you email them to me? - Uh-huh.

So you just came around to tell Madison that you'd sent an email.

Come on, Harry.

You can run, but you can't hide.

Yeah, OK...

She wants to know why you didn't call her yourself.

Because it's awkward.

10 or 12 years go by, and I just pick up the phone and

ask her about a dead student?

Virginia is not just some ex-girlfriend that you lost touch with.

Evidently, at some point, you married her.

All right, well, she and her colleague

are on the same page about Margo, an accident.

Her colleague, Duncan Lovell.

- Yeah, that's Professor to you. - Ugh, you sound just like him.

Am I detecting a sort of love triangle here?

He was Ginny's supervisor, mentor back in the day.

And now they're both Margo's supervisors, or were.

You want me to focus on Duncan.

I can't let my opinion cloud my judgement.

- Gotcha. You think Duncan did it. - I want it to be Duncan.

Access cards for the lab are encoded with a unique digital ID,

so every entry and exit is logged.

With names?

It's numbers currently, but I'm working on it.

- Who is that? - Oh, this is Professor Duncan Lovell.

Quite the rock star scientist back in the day.

Back when he was Virginia Henare's supervisor, you mean.

Do you think the handsome professor swept her off her feet

and away from Harry?

I think... that we shouldn't gossip about our friends.

Boring.

Hey.

Make sure you know the location of safety showers,

eyewash stations, fire extinguishers,

and today, I've got my safety buddy here

cos we're dealing with carbon dioxide.

Say hi, safety buddy.

I'm getting teacher's pet vibes here.

Which teacher are you thinking, though,

Professor Henare or the science rock star?

Why not both?

Hello.

I hope this is a better time to talk.

I have five minutes before the Chem 303 students show up.

Where were you the morning that Margo died?

Gosh, that's a bit on the nose.

Well, neither of us have time for me to cushion it.

Fair point.

I was... at home when I got the call about the fire.

- Anyone there with you? - My cat.

Did you make any calls, send any emails or receive any deliveries?

I'm not sure.

But what I do know is I wasn't here

watching my best student die of carbon dioxide poisoning.

On the nose.

So, friend of Harry's, is that all that you are?

Oh, sure.

Yes, well, we are close.

- What's he told you about me? - Not very much.

But I do get the feeling

that he's not much of a fan of Professor Duncan Lovell.

Oh, grow up, Harry.

Sensing a story there.

- Not really. - Oh well. I won't ask.

Not you anyway.

- Where can I find Professor Lovell? - In his happy place.

- Gidday, professor. - Alexa.

Hello again.

I just wanted to have another little chat

about Margo Booth, if that's OK.

- And you came all the way out here? - Oh, why not? It's beautiful.

It is.

Do you get out here much?

- A few times a week. - Oh, lucky you can manage it.

Well, it's why I have minions.

Oh, you mean research students?

Yes. Sorry, I shouldn't say things like that, should I?

Margo was working alone at the lab that morning while I was...

- You were...? - Oh, out here, probably.

- Just probably? - No, definitely.

Because when I got back to the car,

there were the messages letting me know.

Were you surfing with anyone that day?

Oh, there's bound to be some others.

No one I can call to verify, if that's what you'reafter.

It is.

I tend to be in the zone.

I can relate to that.

Tell me about Margo.

She was a very promising young lady,

meticulous attention to detail,

the best work ethic I've observed in a student.

It's one of the reasons she won the doctoral fellowship.

- Were there other applicants? - Of course.

Are they still around?

Yes. Caleb Moore, he lost out to Margo,

but we managed to find him a part-time role.

So when she died, the fellowship transferred to this Caleb Moore?

Look, he's been working really hard to make up for all the time

we lost after the accident.

- Uh-huh. - He didn't benefit from Margo dying,

if that's what you're suggesting.

Apart from receiving the prestigious fellowship he wanted.

Meet Caleb Moore, research assistant, PhD student.

Oh, he's got a weekly slot on student radio talking everyday science.

He's also got Margo's fellowship.

But is that a strong enough motive for murder?

If you're ambitious or jealous or you just need the money.

Isn't he in one of Margo's videos?

Say hi, safety buddy.

Oh, the safety buddy who wasn't very buddy-like.

And Margo's loss is definitely Caleb's gain.

Our research could change the game for plastic pollution.

- Well, that sounds really exciting. - It is.

Especially for you, right? Now that you're the new Margo Booth.

You took over a role, no longer the bridesmaid.

I see what you're saying.

So, for a start, I'm a scientist, not a kids entertainer.

Oh, you're referring to Margo's educational videos?

The life of a PhD student in the chemistry faculty.

Well, I think they're great, aspirational.

I've got a slot in student radio, Everyday Science with Caleb.

All the shows are available online if you're interested.

What interests me

is why you mock Margo's content creation but it's OK for you to do it.

Margo was a great girl.

- Woman. - Woman.

But she ignored the buddy system,

and it nearly lost us all of our research.

It could've been a complete disaster.

A brilliant woman with a big future lost her life, Caleb.

There's no 'could've been' about it.

- I liked Margo. - Not getting that from you.

Because we are working on a project that could

literally change the world.

And you, you're chasing a silly theory about an accidental death.

Well, I best leave you to it, then.

That security log, have you turned numbers into names yet?

I have, but there's no one of interest going in with Margo.

Margo arrived at 8, never left.

Take a look at the day before.

OK, so going all the way back to the Friday morning...

our research students arrive,

professors arrive all around the same time.

And when do they all leave?

Virginia was out of there later that night; Duncan too.

And Caleb...

Let me hazard a guess.

- Wow. - He didn't leave on Friday, did he?

- Hi. - How did you get my address? - I'm a police consultant, Caleb.

And your supervisors are very keen to help me out.

Wait, Virginia and Duncan know you're speaking to me?

Can I come in?

- I already answered your questions. - Oh, but I've got more,

about you swiping into the lab that Friday morning,

the day before Margo died, and never swiping out.

I did so. I left on Friday afternoon.

Without using your card?

I always use my card, you know, in case they're logging out hours.

Caleb, there's no record of you ever leaving that day.

You think I stayed the night in the lab?

And waited for Margo to arrive the next morning? Yeah,

that's exactly what I think.

No. No. Uh...

um... what if, what if my, um, card is defective?

Let's say that it is.

Where were you that Saturday morning?

Here. I was, I was right here.

Alone?

Do you want me to prove it? Is that what you're saying?

Well, I mean, that'd be handy, especially for you.

OK, just stay here. Don't go anywhere. I'll be right back.

Oh... God.

- And that's for you. - Thank you.

My childhood dream, never-ending supply of ice cream

and kids who want to be my friend.

I'm lactose intolerant, and kids are messy and emotional.

I've got goals outside of ice cream.

Did you know one of the fastest selling paperbacks of all time

was developed from fan fiction?

I just need to finish my PhD, then land a full-time academic job.

Then I can use some of my research hours to write and get paid for it.

Did Margo ever mention her colleague Caleb?

Caleb Moore? As in, could you be 'Moore' creepy?

The last time I saw him, we were at this party together.

He wouldn't leave her alone.

Like a stalker?

And then there was that phone call about two days before.

- Yes? - I overheard her. She was upset.

He was trying to take credit for her work or something.

She said she was gonna report him.

- Did she? - Mm-hm. I heard her raise her voice.

She said, 'This isn't fair. I'm going to report you.'

Morena.

- Alexa Crowe, would you like a muffin? - Oh.

- One of my students made them for me. - Greaser.

She's worried that I'm too busy to eat,

but, yes, probably... not that I'm complaining.

So, this, uh, Caleb Moore, he's is odd one, huh?

- Why, are you still interested in him? - Yes, very.

Especially since I visited him at his house.

Plus, he had an argument with Margo in the days before she died.

She was gonna report him for something.

- I don't know anything about that. - Mm.

- Oh. - Hello.

- Hello, Professor Lovell. - Caleb, are you all right?

Yes. Yes, very, very good.

Miss Crowe, Detective Crowe, what do I call you?

Alexa's fine.

- Can we please have a chat? - Yeah, yeah, 'course.

Would you like me to come with you, Caleb?

No. No, no, no.

I'm just, um, helping Alexa to understand our safety protocols.

- Good man. - Yeah.

I'm not entirely sure why you left.

- I looked in your fridge. - OK, yeah, that makes sense.

- Why would you look in my fridge? - Blood on the door.

I can... There's a reason,

...for the treasure trove of body parts?

You're make me sound like a freak.

Now, Caleb, I'm not a newbie.

I know those are animal parts and not human,

but I also know that your kitchen has almost no cooking equipment,

and even if it did, hearts and eyeballs don't make the best cuts.

Oh, jeez.

So tell me, what's the reason for the home horror fest?

Here we go.

Let's do it.

Let's do...

There's more.

You've got this, Caleb. You can do it.

Yeah, I do.

Yeah, I can.

So, what is it, haemophobia? Ommetaphobia?

All of the above.

Vasovagal response 100% of the time.

I only made it through my undergrad studies with hypnotherapy.

Virginia would laugh me out the door if she found out.

Even Duncan, I mean, I don't think he'd be impressed.

What kind of scientist

can't dissect a cow's spleen to identify contamination?

So what is this, exposure therapy?

What's Margo doing there?

It was her suggestion. She wanted to help.

You confided in her?

Well, she guessed.

- So do you believe me now? - Believe you what?

That you wouldn't do anything to hurt the woman

who discovered your humiliating, career-threatening secret?

Apparently, you phoned Margo the Thursday before she died.

- She was upset. - No. No, I didn't.

According to Margo's best friend, you did,

something about wanting to take credit for her work.

She threatened to report you.

Hold on, what best friend? You mean the flatmate?

Keri-Anne thinks you were bothering Margo.

Then why would she come to my place to help me?

That was her idea, not mine.

And Keri-Anne is the weirdo, OK? She's scary.

They weren't friends. Margo, she was obsessed with her research.

Her friends were here in the science faculty.

Her friends were...

me.

I'm in ice cream heaven.

You're still with Keri-Anne Harker?

I've been trying to get info out of her,

but she's a surprisingly popular ice cream girl.

Keep smiling. She was never besties with Margo.

According to Caleb, she's playing up their friendship.

So it's a he said, she said?

Yes, it is. Keri-Anne is a weirdo, he says.

And if the guy with a freezer full of hearts says,

Sorry, what? I'm going with 'she said'.

Keri-Anne's got dry ice here.

OK, keep calm and step away from the murder cart.

- Alexa. - Oh, Duncan. Hello again.

- Is Caleb all right? - Yeah. Actually, he was quite helpful.

Look, I'm just a little uncomfortable

with you pressuring my students like this.

It just seems a bit off.

I'm not pressuring anyone. I'm just asking a few questions.

Still, it's a bit confronting for them.

Caleb wants to find out what really happened to Margo as much as I do.

What really happened? We've lost a divine young woman.

And that is hard enough without you suggesting someone wanted her gone.

It's disgraceful, actually.

Professor Lovell was not so friendly today.

Oh, here we go, academic transcripts and records.

- Do not ask how I got in here. - Never.

- Margo's? - Keri-Anne's.

- Mm-hm? - Hmm.

She has had several extensions to her PhD deadline.

The latest one, guess when.

She was supposed to submit her thesis a few weeks after Margo died.

But now it's not due for another six months.

She applied for an extension after Margo's death?

The day after.

And what she officially applied for was bereavement leave.

Without it, she would have had to submit by the original date,

and if she didn't, she was gonna be dropped from the PhD programme.

Now, is that enough motive for murder?

When you've put that many years of your life into the project,

I'd say so.

A+ for you, Madison.

Looks like we gate-crashed the party.

Or a funeral.

Welcome all to my reading.

- I think she saw us. - Yeah. It's hard to miss us.

As I crossed the threshold from student to lover,

'I've never felt so alive

'even though you

'were so very dead.'

'You already taught me so much as my professor.

'But now, in this new role, my body shivered.

'And not because your body was cold,

but because of the hundreds of years...'

- My pleasure. - Thank you so much.

Thank you.

Thank you so much for coming to my reading. What a nice surprise.

Keri-Anne, where were you the morning

that Margo died in the science lab?

Why are you questioning me?

Because you overstated your friendship.

Perhaps to get a bereavement extension on your PhD...

...which you did in fact do.

Oh my goddess. Getting an extension was the last thing on my mind

when I heard what had happened to poor Margo.

BS. You applied the next morning.

If I'm guilty, why did I go to the police?

So you can apply for a further extension due to the stress

of the ongoing investigation.

Look, I loved Margo.

- What was her star sign? - Sorry?

What's your bestie's star sign?

She gives Virgo energy.

- Is Virgo late December? - Alexa.

Margo was a Capricorn.

So I'm gonna ask you again.

Where were you the morning of Margo's accident?

I hosted a paranormal romance write-in.

There was at least a hundred attendees.

I got a whole novella completed.

- Where was this write-in? - Online.

- Was it recorded? - No.

But... I can give you the novella.

Oh.

Chowder, hide your eyes.

It's pretty racy, huh?

Madison, you have to stop me reading this.

This is super quick just to say hi,

and shout out to Archimedes and another one to Marie Curie.

That's all. Stay tuned, lab rats.

Play that again.

This is super quick just to say hi,

and shout out to Archimedes and another one to Marie Curie.

That's all. Stay tuned, lab rats.

And that was that. She went in the next morning, never came back.

Eureka.

What, you solved it? What am I missing?

The Archimedes principle, he was in the bath one morning

when he discovered this

amazing theory about water and, and volume and measurement.

But then he ran through the town shouting, 'Eureka!'

So you think that Margo discovered something?

Well, whatever it was, I think it's in those notebooks.

Which we can't find.

Well, she went to the lab the next morning. Maybe she took them.

So, what we have is a swipe card situation,

a phone call and some missing notebooks.

- Tea and a long black. - Thanks, bro.

So, does your wife know about this?

No? Not funny at all?

- They have an open relationship. - Different strokes and all that.

So, do you? Did you have an open relationship?

No kind of relationship.

All right, I get that. But why the big secret?

You know, Ginny always said back then the hardest part of what she did

was securing the funding.

So she married young Harry for his money? I find that hard to believe.

Well, you're half right.

We were best mates since high school. Never any romance between us.

OK, so how did I know that you'd be a best girl-mate kind of guy,

even in your youth?

Anyway, Ginny was always focused on her study,

her future career, but it was a struggle,

textbooks, course fees, rent... a decent student allowance

wasn't a thing.

Unless...

- you were married. - Harry, you didn't.

She was in need. And I knew even back then that I was probably gonna be

a commitment-phobe for the rest of my life.

So you married your best friend for a student allowance?

I mean, I married my best friend too, but I was in love with him.

You know, it wasn't like that for me.

It did not stop me getting pissed off when

Professor Duncan turned up on the scene.

All of a sudden, we couldn't have a conversation

without his name coming up.

One day, I pointed out that she was always fetching coffee for him,

running around, doing his chores.

- Like a minion. - Ginny got defensive, we argued...

and then we just never made up.

- A best friend break-up. - Yep.

- That's rough. - Yeah.

So rough that I am not going to tease you

about marrying for a student allowance, though it is illegal.

That thing you said about securing funding, though.

Yeah, what about it?

It's probably the same issue today no matter how successful you are.

Where are you going with this, Alexa?

Towards a motive for murder.

Should I be flattered that you're stalking me out here?

I'm just impressed that you manage to spend so much time on the ocean

instead of working on that multi-million-dollar research project.

Work-life balance is important, Alexa.

- Do you mind? - Sure.

I suppose that eureka moment might come to you

when you're catching a wave.

Exactly.

Except that you already said you get in the zone when you're surfing.

What's this about? Do you have any actual questions for me?

Oh, yes, yes. It's about your minions, as you call them.

I've noticed that you have co-authored a lot of research papers

during your career.

- Of course. - And a lot of those are collaborations

with your PhD students

going all the way back to Virginia Henare.

So forgive me if I'm a little blunt, Professor Lovell.

Please, please don't stop now.

But are they riding on your coattails, or is it the other way round?

What are you accusing me of?

Well, it's obvious that you whack your name

on your students' research papers, and your academic output is massive.

It's not uncommon.

To the extent you do it?

You must be so busy, it's amazing that you find time to get out here.

Do you have any idea at all how a faculty works?

I am trying to, professor.

- That's why I've come to you. - If you'll excuse me.

Eureka.

Nice work, Madison, very nice.

Hmm.

- We might need a translator. - Luckily, I know just the person.

Caleb, my friend. I need your big science-y brain.

- Wait, those are Margo's. - Full marks!

I think these show what she was working on at the lab.

Look here. Now, the dates in the columns coincide with weekends,

but there's a lot of question marks,

so whatever she was trying to figure out was really challenging.

- Do you think you're up to the task? - Of course.

This might take a bit of time.

Oh, that's fine. I've got something really important to do while I wait.

Margo, she did it.

She worked it out.

- Oh, a eureka moment? - God, she was so good.

I mean, how can she suddenly just go,

- 'Why not rumen?' - Rumen?

You know, the largest part of a cow's stomach.

- Oh. - Think, like, a 55-gallon rubbish bin.

And cattle already have these natural plant polyesters

in their diet, so if you think about it, it makes sense.

And, hey, we're in New Zealand. We're not short of a cow

so upscaling would be so easy.

What's the matter?

She never got to do anything about it. She never got to tell anyone.

Actually, Caleb...

I think maybe she did.

Morning, lab rats!

Have you met Madison? She's my...

- Wait, what are you? - Well, you're my mentor.

And that's kind of what you two were to Margo, right?

Alexa, I normally admire a tenacious woman,

but this is too much. Back off.

Hello, you must be Harry's wife. I've heard next to nothing about you.

Virginia's right, Alexa. You're pushing this too far.

She keeps coming out to the surf beach.

Now, I'm glad you mentioned that cos that's where you said you were

the Saturday morning that Margo died, surfing.

- I believe so. - I don't.

Alexa's been listening to Caleb Moore's slots on student radio,

and she noticed that the show he's on also does a daily surf report.

So just out of interest, I went back to that Saturday

and listened to the podcast, and guess what I'm gonna say, Duncan.

Can you guess?

Call security, will you, Virginia? Get these bloody women out of here.

What she was gonna say is there was no surf that day.

Student FM's surf girl gave the West Coast a zero out of 10.

So somebody's telling fibs.

Uh, so you're suggesting that Duncan was here with Margo?

You really are clutching at straws.

Except that I'm not, cos you were here, right, Duncan?

Now, hear me out.

No one could understand why swotty Margo would break the rules

to work alone without a safety buddy, so that's what we focused on.

And then Madison figured out...

...that someone in this faculty swiped in on the Friday morning

but didn't leave that night.

Why are you both looking at me?

As if Duncan would allow a student to come to harm.

- He elevates people. He doesn't, - I'm gonna have to stop you there.

You see, two days before Margo died, she discovered something,

and she brought it to her professor, her mentor,

who she looked up to, who she was expecting to impress.

But you weren't impressed. You were pissed off

because this baby scientist was gonna be a star.

She was gonna take all the glory, all the money.

What did Margo discover, Duncan?

Well, whatever it was,

she'd written it all down in her little pink notebooks,

which, unfortunately, are missing from her house.

And we thought if we located those notebooks,

things might become clearer.

So Madison came here yesterday, and she took a little look around.

- Sorry, what? - Oh, we have an access card.

Speaking of cards,

that was brilliant how you swapped yours out for Caleb's,

cos it looked like you left when you didn't.

He swiped out on your card on the Friday night

while you stayed in and got comfy.

Well, Madison could not find the notebooks in your office,

but she found something else.

- Your sleeping bag. - And then so did I.

Margo's notebooks.

What, What did Margo discover, Duncan?

No idea. Nothing. Those notebooks that you're so interested in, Alexa,

they're just full of undergraduate musings.

Well, that's not what Caleb Moore thinks.

He's taken copies, and he's writing up Margo's work as we speak.

What's the matter, prof? You've already written it up, haven't you?

Because that's the other thing that Madison found in your office

on your computer.

You're about to publish Margo's work,

but you forgot to put her name on it.

Duncan...

what did you do?

You said that you'd go to the next stage

but with you at the helm, controlling the work, the money.

But Margo wasn't gonna have that.

No, she's from this new generation that's not gonna let any man

take credit for her work.

So when you put the pressure on, she threatened to go public.

She was gonna tell everybody that you've been exploiting students,

accepting gifts,

and that you're hardly ever here

except to put your name on someone else's work.

And if all that came out in this day and age, you'd be cancelled, mate.

Oh, for pity's sake.

So you talked Margo down,

said you'd meet her, test her theory, run some experiments.

You asked her not to tell anyone,

and she didn't because she believed you.

And that was Margo's fatal mistake.

Because you already knew what you were going to do.

You weren't going to let Margo run off with your retirement plan.

So you decided that this brilliant student and her discovery

needed to go away.

Oh my God.

The work always comes first, Virginia. You know that.

Yeah, whose work?

You would've been happy with that child running the next stage?

You and I, working under her?

- Because that's what would've happened. - Oh.

- That's what she wanted. - Oh God, that poor...

- Ginny, wait, please, don't hate me. - My God.

I could've lost everything.

Thank you, friend of Harry's.

You're welcome.

- Divorce papers. - Oh, eh?

Is she keeping her name?

Actually, no. Ginny thinks it's time to be herself.

You know what she is doing?

The Margo Booth scholarship?

Financial support for young women

starting out in the study of chemical science.

So they don't have to marry young men like you.

Seriously, that's a really nice tribute to Margo.

Yeah.

she must be a good woman, your ex-wife/best friend.

- She's OK. - But you like your new bestie best.

Sure do.

Cos what's not to love?

- Alexa is taking a vacation. - Yeah, right.

She's in Fiji.

50 bucks says she's working on more than just her suntan.

It's like the universe just put us together at the same time,

so justice can finally be served.

The universe didn't put me here. You did.

What on earth are you doing here, Alexa Crowe?

I go after creeps like you for fun.

You having fun yet?

Who was that? Do you have a bloke with you?

I just have a thing for... unavailable women.

Make up your mind, Alexa.

Can't just take a vacation, can you?
