Return to Paradise

And our ground - breaking shark research

is at the very centre of that vision.

I am extremely proud to announce that Sharktech -

formerly a part of South Coast University -

has begun to attract the attention...

I'm way behind. I'll see you back at the lab.

You don't want to stay for the pitch?

I wrote the pitch.

This is a monumental moment for us.

For that, I would now like to hand over

to one of the world's leading shark experts,

Associate Professor Brian Chandler.

Uh, thank you, Asher.

We've been carrying out genetic research

into how white sharks stabilise and adapt their DNA.

We've also been tracking them to...

Why don't you just leave them alone?

I'm sorry, you're from? You know who I am.

Can you explain how trapping sharks on drum lines

is impacting on fish populations? It's not.

Well, that's not what the fishermen are saying.

Thank you. The...

If we could please bring it back to Sharktech's research.

Clementine, a follow- up?

I'm charging you double on the way back.

Course you are.

Good morning.

Why didn't you ask him to leave?

I'm operations mate, not your personal security guard.

He made us look like idiots.

Brian, forget about it. It went well.

And tomorrow morning there's going to be

articles everywhere about the amazing work

going on at Sharktech. Yeah?

Our work, which continues.

Are you going out on the boat?

Yeah, I've got to check the drum lines.

I'll drop you down there. Yeah.

I've got an idea I want to pick your brain about.

All right, Brian's out and away.

Well, thank you both so much for this morning.

Shame about what's- his- name interrupting.

Right, ten minutes to catch up on the rest of the day.

Mm- hm.

It's illegal without a licence, you know?

She's a pet.

Mm? What's her name? Caroline.

How old?

14 months.

Date of birth? 31st of July, 2024.

Mm.

Cancer? Leo.

Well, make sure she's on a lead.

Will do.

It's a surprise for daisy's mum's birthday,

she loves them.

Sorry if this is a stupid question,

but aren't you meant to be in London?

Yes.

So, why aren't you?

Well, it sort of involves... Stop.

No, let me say it.

No, Mack. Stop! Hey!

He looks too far gone.

Here.

Oh.

J ust watch out for the... Mm- hm.

What do you think? Out fishing?

No.

No rods, no lines.

Hm.

"Brian Chandler."

Works for Sharktech.

Looks like a heart attack or stroke.

There's not much we can do for him.

The morgue, they can come and, uh...

He's wearing a silver chain.

Only a crime against fashion.

No, it's discoloured.

Rotten eggs.

No way. Yes way.

Tarnished metal, rotten eggs. Hydrogen sulphide gas.

But how could he be gassed?

We're outside on a boat.

There's faint skin irritation around the nose and mouth.

What if it was held to his face?

That'd make sure he inhaled enough of it to kill him.

This is murder. It might be murder.

I'll know more when I autopsy him.

No, it's murder.

See what else you can find on the body.

Colin?

Get dressed.

He was my right- hand man.

He's been researching sharks his entire career,

even before we met.

This is awful. Here you go, hon.

Thanks. You OK?

My husband.

Craig Park. Operations.

Did you see Brian this morning?

He spoke at the press conference.

We're on the brink of some significant breakthroughs

so we've spun off from the university.

And more chance of selling out to cosmetic companies

who are desperate to break anti -ageing? Mm?

Good pitch.

Yeah, well, the science is bigger than just a pitch, detective.

What happened after the press conference?

I've got it all here.

Susie Huen.

She's one of our team.

A Phd in marine biology and a wonderful scientist.

Sorry.

The press conference was at 9 a.m.

out the front of the lab.

Then Asher dropped Brian at the boat.

He had to check the drum lines.

When was this? Uh, I don't know exactly.

From here to the dock, about 10:30?

Then what?

Well, we came back here, and we... We got on with our day.

11.

Just us.

Is there CCTV at the dock?

Yeah, I can help you with that.

Out in the shed.

Oh, what do you know about hydrogen sulphide?

Why?

We think it may have been a factor in Brian's death.

Well, we're scientists.

Even first year chemistry students

know everything there is to know about H2S.

I wouldn't know anything about gas.

I left school when I was 16, so...

You're a boatman, aren't you?

Don't all boatmen know about hydrogen sulphide in confined spaces?

Say, when you're cleaning the head, for example.

I suppose so, yeah. Ah.

Probably got what you need to make it in this room.

Yeah, well, I hardly knew the guy, so...

Yeah, but Brian was too big - brained to talk to me.

OK, so that is the last 24 hours.

That's all we've got.

I'll leave you to it, then.

OK, OK.

Here we go.

10:38...

...which fits with Asher driving him down there

at around 10:30.

She's on her way back to the lab now to meet the others.

Brian gets on the boat,

and now we're just waiting for our killer.

What?

No, that's not possible. Where's our killer?

No. As far as we can tell, the only people that knew

he was going to be on that boat were the Sharktech crew

and they were all back at the lab by 11.

That's not enough time to get down there,

murder him and get back.

How could any of them murder Brian

when he was on a boat in the middle of the water?

Oh, hey, hey, hey! dead bloke alone on a boat,

is that right?

Oh, that's a new one.

Hey, mind you, I nearly choked on an oyster

on Mick Michael's tinny, New Year's, '99, the Y2K.

Admittedly, I had had a few chardies,

so I was not at my best, but still,

there, but for the grace of God, like...

They've sent through the footage of the press conference.

I've been scanning through it a bit, and I also got the photos

of the victim and the lab team right here.

How do you want to run it? You want the board?

Yeah, I cleaned it up, got it ready for you.

Hey, mate, mate, mate.

Don't be shy. You're the boss now. Yeah.

About what?

Brian Chandler, murdered in the middle of the ocean.

Senior scientist at Sharktech found dead alone

on board Hakari, the research vessel for Sharktech.

He got on board alive at 10:38 a.m., according to the CCTV.

He sailed out to sea while the only people

who knew where he was - the Sharktech crew -

were all back at the lab.

Somewhere out there, he was gassed with hydrogen sulphide,

we think held to his face on a cloth.

And he comes ashore dead to me and Glenn at 11:30.

Any questions so far?

Just the one, love.

What the heck are you doing back here?

Yes, Mackenzie. What the heck are you doing back here?

Mm- hm. Mm. Mm- hm. It is a good question.

It is a fair question.

But a man is dead

and we have work to do.

Detective Sergeant Clarke...

...we're gonna have to have a conversation about this.

You understand?

Yes, Boss.
