This giant cephalopod—like sea creature

half octopus, half shark

is, many believe, the stuff of fantasy.

The kind of fictional monster Jules Verne might dream up.

But then, there are those more open—minded souls, like myself,

who believe this gigantic cryptid

to be as real as you or I.

I will present to you the evidence I have collated

proving this animal is no mere figment of the imagination.

And it all begins with the first sighting,

off the coast of Saint Marie in 1823, by this man...

...a pirate by the name of Pierre Laffite.

Pierre Laffite was my great—great—great—grandfather.

I tell you no lies still got the journal he had

when he was pirating away,

passed on from generation to generation.

And that's why this is the only boat trip

where you can experience the exact place

my ancestor witnessed the Lusca.

Roll up, roll up!

You know you want to!

And I promise you guys, you will not be disappointed.

So, how was it?

Are you a believer now?

To be honest...

...I think I'm even less of a believer than I was before!

I don't know why you bothered.

Because I want to be prepared.

I'm afraid nothing can prepare you for my ex—husband.

Either that's him,

or we've come to a soup kitchen by mistake.

Hello, Giles. Cara.

It's been a while, hasn't it?

Oh, er...

Stop it.

This is...Rory.

Ah, yes.

Didn't, er, realise you were bringing him.

Nice to meet you, Rory.

It's great to finally meet you, Giles.

Can't wait to hear all your stories about the Lusca.

Absolutely fascinated about it.

Ah.

Um, would you... Would you like a glass of wine?

Just a cup of coffee'll do me, ta.

Um...let me see if can find a waiter.

Sit down?

So, how are you?

] mean, you know, the...

the anniversary.

Feels strange to be back.

Like it was only yesterday.

I'm taking the boat out later to...

to where it happened, if you fancy joining.

You know, remember him together. No, I'd rather stay here.

With Rory.

Poor guy.

Al right, my lad do?

The Lusca!

It's just a bad dream.

Yeah.

Where have you been?

Just went for a walk, that's all.

Thanks.

Morning, sir.

You good? No. I am not good.

What's wrong?

Turns out I am an uncle.

Yes, Mum. Yes, I understand.

But I came to visit Uncle Merv anyway.

That's Eloise.

The niece I didn't know I had.

So you're her Uncle Merv!

No, I'm not.

I mean, yes, I am her uncle, but not Merv.

Never Merv. Understood? OK.

Clearly touched a nerve there.

Well, I kind of miss him.

So she's Solomon's daughter?

I don't know why he couldn't just tell me that

in the first place. He could have just said,

"Well, as it happens, I do have a daughter."

Are he and her mother together?

Not for some time, apparently.

She's supposed to be staying with her Auntie Vondra,

but she doesn't like it there, so she ran away and came here.

We've got a case, I assume?

Oh, my God!

It's not a murder case, is it?

Please let me come on a ride—along, Uncle Merv!

Please!

Right, so, firstly,

you're not coming on any ride—along.

And secondly, it's not Uncle Merv.

It's Mervin. Remember?

Hi.

I'm Naomi, by the way.

I work with your Uncle Merv.

Right.

Go pack your stuff, young lady. You've got a boat to catch.

I am sending you back home to Antigua.

Whatever you say, Uncle Merv.

And it's not...

I like her.

Victim's name is Giles Parry.

58 years of age.

Body was found floating six miles out at sea.

Sergeant Fletcher is with the coastguard now.

A couple of fishermen going out early this morning

came across the body,

but paramedics reckon he'd been in the water since last night.

Thing is, this is already causing a stir around the harbour.

Why's that?

Because of those marks on his body.

They're all over his front and his back.

And the bruising, here.

Some people are saying it was caused by the Lusca,

and that's what killed him.

Sorry, what?

It's a sea monster.

A sea monster?

Like a local legend kind of thing.

Half shark, half octopus.

Wraps its tentacles around you and drags you under.

Hence... A sea monster?

Not everybody believes in this thing.

Most people don't, but... Er, do you?

No, but it's still part of our history,

part of our culture. Right.

Well, we can knock that theory on the head

as a possible cause of death, all right?

Except there's a little more to it than that, sir.

That's why he's here.

I always wondered whether this would come back to haunt me.

Seven years ago yesterday,

Giles Parry's 16—year—old son, Benjamin, drowned at sea.

In the exact same location

as Giles's body was found this morning.

A local fisherman told me that

Mr Parry had sailed out to that spot yesterday

to pay his respects.

Then he ended up dead himself.

Mm-hm.

Was it stormy yesterday?

Called the harbour master.

It was calm for the last 24 hours.

And do we know what time he left the harbour?

Just before seven o'clock, according to the GPS.

Also, there's a boat mechanic who's been fixing Mr Parry's engine.

He saw him leave.

He says there was definitely nobody else on the boat with him.

It arrived at the final destination half an hour later.

Radar shows no other boat near it at any point.

So what happened to him?

How did he end up dead with all those...

weird markings on him?

Unless, you know, it was the Lusca.

Hate to break it to you, Officer Rose,

but sea monsters don't exist.

No, yeah, I know.

But, it would be cool if they did, though, right?

Yeah. What's that?

It's a bullet.

Our victim wasn't shot, right?

No. And there was no gun found on the boat?

Not that I've found so far.

So what is that doing here?

I don't know what happened on that boat,

but the fact that we found this on it means it's suspicious.

I think someone else was there, you know?

I'm going to talk to Catherine.

From what I know, Giles Parry was an isolated figure,

but he did drink at her bar, and he would talk to her.

I'm also going to contact the Guadeloupe police

and request the Benjamin Parry case files.

What, so the search back then

wasn't led by the Saint Marie team?

As it was the Guadeloupe coastguard

who was first contacted when the empty boat was discovered,

they staked their claim.

I bet that rankled.

I did push for us to have a role,

but the senior investigating officer wasn't interested.

There's some people on Saint Marie

who think I should have pressed harder,

especially when they ran into a dead end early on.

It's always been felt more could have been done.

Done by me.

Considering I am already persona non grata,

I would like to do my bit to try and solve this case now,

and win back the community's trust.

I've located the victim's ex—wife.

She and her partner are staying at a hotel just outside town.

We arrived here two days ago,

to mark the anniversary of Cara's son's passing.

And I'm sorry to ask, Miss Smart,

but your son Benjamin,

why did he take the boat out on his own?

Giles had always been into UFOs and aliens, that kind of thing.

Our holidays were spent visiting Loch Ness,

or the Bermuda Triangle.

The Lusca here on Saint Marie?

Ben was getting even more fanatical than his dad.

That's why he snuck out on his own,

and he took the boat we'd hired out

for a last—ditch sighting of the Lusca.

The weather turned bad. The sea was rough.

He never came back.

I kept hoping they'd find him alive,

with a life jacket on, just floating somewhere,

but, as time passed, you have to accept

that he's not coming back.

So you returned home to England?

After ten months.

Giles and I were arguing nonstop by then.

I just needed some space, some time to process it all.

Whereas he...

Giles was convinced the Lusca took their son.

He became obsessed.

That's why he stayed on here

when I left, to try and prove the Lusca exists.

And he really, truly believed in it?

And yesterday, did you see Giles at all?

We had an early dinner at five.

It's great to finally meet you, Giles.

And how was that? How was Giles then?

It was fine. You know, quiet.

Giles was Giles.

Still as delusional as he ever was.

Did Giles ever own a gun at all?

Not while we were together.

And I struggle to believe he bought one

while he was out here. What exactly happened to Giles?

You said that he was found dead at sea.

I assumed it was an accident.

But is there more to it than that?

Well, we're not sure yet.

We're still working on that one.

Yeah, my friend's dad swears he saw the Lusca one time.

OK, Seb, come on.

He was never the same afterwards.

Let's keep our focus on the case.

Auntie Vondra!

I mean, Vondra.

Eloise wasn't on the ferry. Where is she?

I'm worried sick!

Vondra, Vondra. It's all right. She's back at my place. She's safe.

There you go. Thanks.

OK? Look, I'I call you back in a bit.

Merv?

Hey, Uncle Merv.

Hope you're hungry. I ordered lots.

Which reminds me, I borrowed your credit card this morning.

Needed it to pay for the boat to get back to Saint Marie,

and dinner.

You really are your father's daughter, aren't you?

I know, right?

What's going on, Eloise? Why are you back here?

Because we need to talk about Dad.

We could have done that this morning.

Why didn't you mention it then?

I was waiting for the right moment.

And before I know it, you're shoving me on a boat back home.

All right.

What about your dad?

We need to work out a plan, Uncle Merv.

A plan for what?

To get him out of prison.

To find evidence that proves he's innocent.

OK, um...

what exactly did your dad tell you about him being arrested?

Just that he was set up and shouldn't be in jail.

That it's a mis...

...carri—something. A miscarriage of justice?

So, we need to help him.

Right?

Why don't you go and get some plates and cutlery, yeah?

Sol, you idiot.

Solomon clearly hasn't told her about the scam he got caught up in

that he as good as shot someone,

and held me hostage.

He's dressed it up like he was the victim.

And she obviously idolises him.

What are you going to do?

I should just tell her the truth, right?

Just...tell her in a nice way, not in a...

your kind of way.

What is a my kind of way?

You know... Sometimes you can be

a tiny bit insensitive.

Insensitive?

Me, insensitive? That is rubbish.

I mean, if anything,

it's everyone else who is too sensitive.

Sure.

That's totally what it is.

Eloise!

Right, um...

I'm off to work now.

So we can have dinner later, yeah? And we'll, um...

we'll talk. OK, Uncle Merv.

Old—school. I like it.

Right, where are we at with the case?

Anything from the lab yet?

Postmortem's estimating time of death

between 7:30 and 8pm.

So, the victim leaves the harbour at seven.

Dies between 7.30 and 8, out at sea,

just after he drops anchor.

And cause of death was internal bleeding

due to a ruptured spleen, which, in theory,

could have been caused by something gripping him tightly,

like the tentacles of the Lusca.

Or, more likely, something else.

Same with the red markings.

Kind of like friction burns. But there's nothing

at the scene to suggest what might have caused it.

What about the search at the victim's house?

Er, Mattie and Seb are just starting.

Sarge! You have to see this!

Ten—year—old Seb would be losing his mind right now.

It's like Sea Monster Central in here.

This is going to be the best search ever.

All right, Officer Rose.

You start on the computer. I'll hit the cabinets.

All right. Cool.

You all right, Sarge?

Yeah, it's just my old boss from Jamaica.

I'll call him once we're done with this.

So, what do we know about our victim?

Giles Parry worked as a paramedic back in the UK,

until he moved out here seven years ago.

Spent all his savings buying a boat

and earned a small income giving talks about the legend

of the Lusca. What about these two?

Any sniff of a motive yet? We're still waiting

on Mr Lyons's background and financial checks,

but he and Cara have been together just over a year.

Met on a dating app.

Now, as he only met the victim for the first time yesterday,

I'm struggling to find a reason for him wanting Mr Parry dead.

But she's a different story.

Miss Smart previously worked as a teacher

before giving that up to write a book a few years ago

a memoir about losing her son.

I skim—read it

and she's very honest about how hurt and angry she felt

about Giles's behaviour.

"When I needed my husband's love the most,

"he disappeared down the rabbit hole of fantasy,

"casting me aside for his futile belief

"in a mythical beast."

I mean, the guy had gone full-on loony tunes, hadn't he?

What was that you said earlier about not being insensitive?

Look, I'm not... Where it gets interesting

is the book's no longer bringing in any money.

She's basically broke.

I spoke to her literary agent in the UK, and apparently

a US TV production company has offered to make

a documentary about her and Giles's son going missing.

It's worth a quarter of a million dollars.

Ah. I'm sensing a "but".

It going ahead was dependent

on Mr Parry agreeing to appear in the documentary too.

Don't tell me.

He didn't want to.

So, we spoke to the staff here.

Well, that dinner you had with Giles?

It wasn't as sedate as you said it was.

According to them, you got quite worked up, Miss Smart.

Angry that your ex—husband was refusing

to agree to the documentary.

Well, that's an exaggeration if ever I heard one.

No, it's not. It's the truth.

Giles, please. I need this.

Why are you being so stubborn?

Because I know what they'll do.

Make me out to look like some mad conspiracy theorist.

I hate you, Giles, so much.

I didn't just lose a son seven years ago.

I lost my husband as well.

He never once thought of me —

that maybe he needed to be there for me.

And even now, years later, I ask for his help,

because, yes, I need the money.

I thought at least he owed me that one favour, but...

no.

Not even that. Thing is, Miss Smart,

we checked with the production company,

and that documentary has officially got the go—ahead.

So now with Giles dying in suspicious circumstances,

and even the locals saying it was the Lusca that did it,

well, it's an even more tantalising proposition

than it was before. You get exactly what you wanted.

No, you're wrong.

I didn't kill Giles to get some documentary made.

I'm not that desperate.

I'd better take this.

So, you want to tell me where you were

two nights ago between 7.30 and 8?

We were here at the hotel.

We were together in our room.

It wasn't me. It just wasn't.

Sir?

That was Mattie. She's with the Commissioner.

They've got something.

This is the closest I've come to actually seeing it —

the Lusca.

I'm still shaking from what happened.

If ever there was proof she's out there, this is it.

I'd moored my boat a few miles out.

The co—ordinates are 16 degrees, 32 minutes, 29.8 seconds north,

61 degrees, 55 minutes, 01.8 seconds west.

There's a sinkhole on the seabed there I previously identified

as a possible home for the creature.

Amazing!

It was just getting dark, when I heard it.

Felt it.

A thud as it hit the bow of the boat, and again,

and then again. I could hear it dragging itself along

as it tried to pull away.

It was her. I know it was.

The Lusca.

I'm going to go back again tonight.

Totally amazing.

Just to confirm no—one here actually thinks

it was the Lusca that was underneath Giles Parry's boat?

Well, I'm not ruling it out, Inspector.

Apart from Officer Rose.

No, of course we don't.

But there is more to it.

Giles Parry uploaded this vlog to his website

two days before his death.

We checked his GPS, and he went back

to the same exact location the next night.

Here.

And this isn't the same location

Giles's body was found?

Where his son Benjamin went missing?

No, that was two miles away, here. But the thing is,

when Giles got back, he deleted this video straight away.

So why? Catherine spoke to him shortly after.

And he seemed troubled.

Everything all right, Giles?

Mm.

He asked me about the Commissioner.

Knew I was friends with him and said he might need to speak with him.

Is it to do with Benjamin's disappearance?

I don't know.

Maybe.

Hang on, these are the same co—ordinates

he talked about in his vlog.

I don't know what happened there,

but it's clearly of significance.

We should go out there.

Do a re—enactment, yeah?

Same time, same place, same boat.

Find out what this X is all about.

I was so hoping you would say that, Inspector.

I can't believe we're going on a monster hunt!

That's not what we're doing.

That's not what YOU'RE doing.

I don't understand.

If you're going on a boat trip, why can't I come?

Because it might be dangerous.

Well, then I really want to come.

Well, you can't. You're staying with Catherine tonight

and we're getting you home first thing in the morning, all right?

But we need to talk about Dad still.

OK.

Look, about your dad.

I don't know what he told you, but it certainly wasn't factual.

What he was arrested for, it's serious.

And I should know cos I was there when it happened.

What are you saying?

Eloise...

Listen, there was no miscarriage of justice.

All right? He wasn't falsely accused.

Your dad is guilty.

So, no, I can't help you find new evidence.

And he'll be in prison for a while.

I'm sorry.

So what happens now?

I just go back home in the morning?

Yeah, course. I mean, that's where your mum is, right?

You don't want to stay with me, do you?

Course I don't.

I've got a life to get on with.

So what's your problem?

This must be Eloise.

It's nice to meet you.

Hey.

Thanks for looking after me.

See you around, Mervin.

So, my chef will cook you anything you want...

Hey, Inspector. Ready for me to cast off?

Uh-huh.

You know, sir,

this isn't exactly the safest boat I've been on.

The two life—rings there are missing their ropes,

so let's hope no—one goes overboard.

Is that the Benjamin Parry case file?

Ah! Just arrived from Guadeloupe.

Commissioner's making a start going through it all.

Can I speak to you for a minute

about a private matter, Commissioner?

Of course.

I got a couple of missed calls

from my old boss in Jamaica today,

and I haven't called him back,

because I think I know what it's to do with.

He phoned me as well, actually.

Damone Dyer was acquitted on all counts.

He's a free man.

I'm sorry.

Have you told any of the team?

Er...

Seb knows I had a boyfriend that I broke up with

before I came here, and...

I told him that I had messed up on a case.

But not that the two were connected.

That my ex is a criminal.

I think I'd rather keep it that way for now.

Nearing the destination now, Commissioner.

Dropping the anchor soon.

Thank you, Officer Rose.

Aye—aye, Captain. Aye—aye.

Must have been frustrating, not having oversight of that case.

The Lusca?

It can't be. Whatever it is,

it's the same sound Giles Parry heard.

You hear that?

Yeah, we heard it.

Can you see anything?

I know it's not the Lusca, but sure sounds like it is.

Can you see anything your side?

No, nothing. Me neither.

Anything now?

Over here! There's something moving.

Where? DS Thomas!

There's something down there. I can see it moving.

Sergeant Fletcher. What are you doing?

That ain't no sea monster.

Mattie!

Stupid woman! You cut my air supply!

That's Kelvin Mason.

He runs a boat excursion business in the harbour.

There's some sort of box under there.

It looks like it's tied to a weight to stop it moving.

Inspector, here's the box we salvaged from the sea.

Your gun. We found it on your jet ski, Mr Mason.

Your keys.

Let's see if one of these fits, shall we?

Your box.

Cocaine, I'm guessing.

Around two kilos.

You'll be charged for this.

Look, I'm just a middleman, all right?

I don't sell it, I don't buy it.

I just make some extra money moving it from A to B.

Giles Parry was onto you, wasn't he?

At first he thought it was the Lusca

making those noises beneath his boat.

I didn't know he'd moored above me.

Couldn't stop myself from hitting it when I came back up.

That's what he heard —

me banging against the bottom of his boat.

And when he went to the same location a second time

to try and catch sight of it...

The Lusca!

I'm going to go back again tonight.

...he discovered what you were up to.

That's why he was talking about going to the police.

Said he might need to speak with him.

I didn't know he'd seen me.

When I went back to the harbour...

I know what you're up to, Kelvin.

...I pleaded with him not to say anything to the police.

Got to know Giles quite a bit over the years.

Helped him with his research a couple of times,

so I thought he might give me a chance.

And?

He told me he'd think about it,

but didn't reckon he could ignore it.

And next thing he's found floating six miles out at sea, dead.

I didn't do that to him, I swear!

This gun of yours. What calibre is it?

It's a 9mm.

Why? Cos we found a 9mm bullet on Giles Parry's boat.

Is that a coincidence, Mr Mason?

Yes, it is.

I wasn't anywhere near his boat when he died.

Mr Mason, you were questioned seven years ago

when Giles's son disappeared, as a witness.

Everybody around the harbour was.

What's that got to do with anything?

So, that also is just a coincidence?

Yes, it is.

Look, if it wasn't you,

then where were you at 7:30 the night Giles Parry

was murdered? Um...

I was taking a drink with a guy who works for me.

Um, a fella named Jackson.

You fancy another?

Call him. Ask him. He'll tell you. I swear.

But...there's something else you all need to know.

Something that happened before Giles took his boat out.

Poor guy. I went to speak with him...

I'll be back in a minute, yeah?

...to see if he'd changed his mind

about talking with the police.

When I turned the corner, he was arguing with someone.

Giles called him Rory.

I know your game, Rory.

Giles said he had evidence of some kind.

I didn't hear what.

But he took out this folder and he gave it to him.

Now, the Rory fella, he didn't seem too happy.

Got a bit physical.

He shoved Giles. Giles fell over and hurt himself.

Then what did you do?

I turned and left.

Right, let's get over to the hotel.

Let's interview our new suspect.

Sir, with respect,

shouldn't we just focus on

solving the Giles Parry case right now?

This isn't a cold case investigation,

and we've got a new lead now.

I just have this feeling the answer

lies right here in front of me.

If only I knew what it was.

OK.

I admit we argued, Giles and I.

It was more than an argument, Mr Lyons,

from what we were told.

Things might have got a bit physical,

but what he was saying upset me.

Which was what, exactly?

That I was only with Cara for her money.

Rory only told me about this last night.

Giles had scrabbled together enough money

to pay a private investigator to look into Rory and his ex.

That's what he found.

So your previous partner invested in your business,

which went bankrupt.

She's still chasing you for money.

It was a total mess I made, financially.

And personally.

Everything in that file, it's all true

apart from the suggestion that I'm doing the same again

with Cara, because I'm not.

I think that's why Giles wouldn't agree to the documentary.

He thought that Rory would take the money.

But I don't... I don't want a penny.

I just want to be with Cara.

So why did you follow Mr Parry down to the harbour

after dinner? Because he was being so unforgiving towards Cara,

saying that she was using

their son's tragedy to line her own pockets.

I wanted him to know the truth.

We're adopting a baby.

Starting a family.

And it's taken all the courage in the world

for her to do this. And you told him?

All Cara wants is to be a family.

I think it threw him.

Then he picked up his things and got on his boat.

And that's the last time you saw him?

Mr Lyons? Rory?

He phoned me...

when I got back to the hotel, about half an hour later.

He was out at sea.

What did he say?

He asked if I loved Cara.

Like he needed to get it confirmed.

And you said?

Yes, I do.

So very much.

Then he just hung up.

So a few minutes before he dies,

Giles Parry phones his ex—wife's new partner

to ask if he loves her.

That doesn't sound like he was being attacked by a sea monster

or murdered. Nope.

It sounds to me like a guy

who'd finally made his peace with the world.

Which kind of makes me wonder, you know...

Did Giles Parry take his own life?

But then try to make it look like it was the Lusca that did it

to prove to everyone that he was right all along?

That doesn't feel right.

Anyway, that doesn't explain the bullet.

Why was that there?

So what happened?

He was alone on that boat, six miles out at sea,

and our three suspects were all on dry land when he died.

How and why did he end up dead?

Maybe these two have the answer.

Just come straight from the lab.

Please tell me it's good news.

There are no striation marks on the bullet.

So they can't match it to Kelvin Mason's gun.

Same make, same calibre, but...

Hang on. No striation marks at all?

Said they've been worn away

by "encrustation of marine organisms".

Corrosion patterns suggest that bullet has been on the seabed

for six to eight years.

Basically, they're just saying the bullet is some sea debris.

But that doesn't explain

how it ended up on the boat in the first place.

Did Giles Parry take his own life?

The two life—rings there are missing their ropes.

Giles Parry worked as a paramedic back in the UK

until he moved out here seven years ago.

Now, the Rory fella, he didn't seem too happy.

Got a bit physical.

Is it to do with Benjamin's disappearance?

I don't know.

He asked if I loved Cara.

Bingo.

I know what happened to Giles, and how he ended up dead like that.

Sir, we've cracked the case.

Benjamin Parry's disappearance.

I think I know what happened.

Spot the difference.

We have a lot to thank this little bullet for.

It's helped us make sense of the present and the past.

In the present, it's what solved the mystery

of your ex—husband's death,

Miss Smart, leading me to finally understand

why and how Giles Parry's body was found dead in the water,

looking like the Lusca, the legendary sea monster

he'd spent seven years searching for,

had finally caught up with him.

And in terms of the past?

We'll come to that shortly.

Throughout this case, we've worked on the basis

that whatever happened to Mr Parry,

it all happened at the same time, while he was out at sea.

But we've now realised that his injuries

were actually sustained in two separate locations.

The first injury the bruising to his stomach

and the rupturing of his spleen

that happened on dry land, down by the harbour,

when you and he tussled, Rory.

You're saying it was me?

You will be charged with involuntary manslaughter.

We know you didn't mean to kill Giles. Far from it.

However, his subsequent fall from your push

caused a serious internal injury.

He just didn't know it at the time.

Oh, my God.

Giles was totally unaware that his life was slipping away.

That's why he walked away from you,

got on his boat and went out to sea.

He was probably already a few miles out

when he started to feel ill.

Initially some discomfort in his abdomen,

feeling faint, feverish.

But it was only by the time he reached his destination,

six miles from land,

that he fully comprehended what was happening.

We know Giles used to be a paramedic,

so it's safe to assume

he worked out what was wrong — that he had minutes left to live.

I'm so sorry.

And if his imminent death

wasn't a grim enough prospect,

Mr Parry also realised that if his body was found on deck,

we would start to question how he was fatally injured,

and the postmortem would more than likely

lead back to the altercation he had with you, Mr Lyons,

and subsequently, some time in prison.

And knowing what you told him about yourself and Cara

wanting to start a family,

well, he didn't want to inflict any further suffering on you both.

That's why he phoned, and asked Rory if he loved me.

That's why he needed to know.

To be sure.

Do you love her?

He could protect you both by making it look like

he killed himself.

It was DS Thomas here who noticed the ropes

were missing from the life—rings on Giles's boat.

The two life—rings there are missing their ropes,

so let's hope no—one goes overboard.

I didn't think anything of it at first,

but then when I started to understand

what happened that day,

that's when I realised why those ropes weren't there.

And hopefully this call will confirm it.

Yeah?

They found the ropes,

tied to the boat's spare battery on the seabed.

OK. Thank you, Sergeant Fletcher.

So, we think Giles knew

that if he tied those ropes around his body tightly enough,

they'd leave red markings, friction burns,

and therefore when his body was found,

he hoped this would also explain his internal injuries.

The bruising.

All so it would misdirect from you, Mr Lyons.

Any similarities to the Lusca was a coincidence.

If that's what happened,

why was his body found floating on the surface?

Because of this.

As Giles sank to the seabed,

by some quirk of fate, he saw this bullet.

Maybe it got caught under a rock,

or wedged in some coral.

We can't be sure, but there it was.

A single bullet, in the same spot his son went missing.

And after his recent discovery of the smuggling

that was going on out at sea not far from the same spot,

Giles was already beginning to suspect that his son's -

your son's — disappearance

might have been for more sinister reasons.

Is it to do with Benjamin's disappearance?

Maybe.

So we believe he loosened the rope,

grabbed the bullet, and allowed himself

to float to the surface,

determined to cling to life

as long as possible.

But by then, it was already too late

for him to climb back onboard his boat,

so with his life ebbing away,

Giles did one last thing.

One final attempt to let everyone know

what he'd discovered on the seabed.

He threw this bullet onto the deck.

A message from him to us to not give up on his son.

That maybe Ben's killer was still out there.

That's what you meant about the bullet helping with the past.

My son's case.

And has it?

That bullet we found.

It turns out it's been sat on the seabed

for the last seven years,

in the exact same location

Giles and Cara's son went missing.

It was fired from your gun to kill Benjamin Parry.

But he drowned at sea.

Why are you now saying he was shot?

This photograph was taken the day before Benjamin went missing.

It's of him and his father outside your office.

And this was taken by one of the Guadeloupe police officers

the day after he disappeared.

Your witness statement is unremarkable in every way,

apart from this photograph.

I had to get a magnifying glass out to really notice,

but in this photograph of Benjamin and his father,

the wall behind your desk is set farther back from the window

than it is in this photograph of you,

where it appears 40 or 50cm closer to it.

Which left me wondering why, less than 48 hours later,

your office had seemingly shrunk.

The only conclusion I could draw was because

a new wall had been built.

Leaving Benjamin's body at sea

would have meant there was a possibility

he could be found,

and if he was,

then it would be discovered that he'd been shot.

Whereas, if you hid his body,

and everybody assumed he drowned at sea,

then maybe you'd get away with it.

But where to hide it?

We have a team at your office as we speak,

about to tear down that wall.

So, if I'm wrong about what's been hidden behind it

the last seven years, you have nothing to worry about.

But if I am right...

...now is your chance to start talking.

That morning, seven years ago...

...it was real early.

But when I got back up with the day's delivery...

he was there recording me on his phone.

For evidence.

I mean, stupid idiot.

Why would you do that? He left me no choice!

I had to act fast.

So I got the lock—box.

Which you moved to a new location, two miles away,

where your smuggling continued

until Giles Parry discovered what you were doing

all these years.

And Benjamin Parry's body?

I took it ashore.

I put him in one of the cases we store all the diving gear.

It's airtight, so...

I spent the whole day

getting everything I needed for that wall.

I spent the whole night building it.

And I have lived with it every day since.

Mind how you go!

And you'll all let me know how it went, huh?

You're with real pirate royalty now, huh?

Knowing that poor boy is stuck behind that wall

will haunt me forever.

Kelvin Mason,

I'm arresting you for the murder of Benjamin Parry.

You do not have to say anything, but it may harm

your defence if you do not mention when questioned

something which you later...

Tis call is from a person currently in prison in Antigua.

Solomon?

Mervin.

I know you said you didn't want anything to do with me no more,

but this isn't about me.

It's about Eloise?

I know she ran away from her aunt and came to you

cos she doesn't like it there.

No, it's because you told her

you were innocent and I'd get you out.

You lied to her.

Maybe I was a bit free and easy with the truth, but...

she's there because she needs you.

She doesn't even know me.

She does, a bit.

I told her some things,

that you were...a good man.

Solomon, I can't... Because you are, man.

I know I'm not.

I have made a mess of pretty much everything in my life,

but that's why I'm asking you this one thing.

This one favour.

Her mum and aunt are cool,

but she's her dad's girl, you know?

Me and her...

There's something special.

And her stupid father's got himself stuck in prison, so...

...she really needs her uncle in her life right now.

Cos you're the closest thing she's got to me.

So, that's the queen.

She's the one to keep your eye on.

All you have to do is find the lady.

This one.

Wrong again.

Was here all along.

I've had people arrested in Covent Garden for that, you know.

Your dad taught you, I assume?

Look, um...

...I'm not good at this kind of thing. OK?

Maybe cos I've never been an uncle before.

What I'm trying to tell you...

You don't know what you're doing.

When you haven't had a proper family in your life,

like I haven't,

you kind of grow up assuming people don't want you,

or need you.

But when you came to me, I should have been there for you,

and I'm sorry that I wasn't.

But if you're up for giving your Uncle Merv a second chance,

then maybe we can try again?

And I can get to know my niece properly?

Because however it might have looked...

...I would really, really like that.

You want to shake on it?

We can do better than that.

After all this time I'd given up any hope

of my son's body being returned to me.

So, to stand here, knowing my boy will be returned home to England,

it means the world to me.

So I'd like to thank the Saint Marie Police Force

for all their hard work...

...in achieving this.

It's a divert from the station.

When all hope was lost,

and it seemed like we might never get the answers...

Yeah.

But I'd especially like to thank Commissioner Selwyn Patterson

for uncovering a truth that no—one else was able to.

I will be forever grateful.

What's going on? It's for you.

You're the man.

You deserve it.

So, er, that divert.

It's for you.

Some guy named Damon?

He said to give him a call when you get a chance.

Thank you.

We're going to go eat, Inspector,

Sarge, Inspector's niece.

Catherine invited us all.

It feels like there's a lot to celebrate.

And you can build up a hunger when you're hunting sea monsters,

you know? Sea monsters? Mmm!

You didn't tell me you were hunting sea monsters!

That's cos we weren't. Well, not all of us, anyway.

Ah, Eloise, this is Commissioner Patterson, my boss.

It's a pleasure to meet you.

You too.

Right, let's go. Come on.

You like playing card games, Commissioner Patterson?

All right, let's not start going down that road, young lady.

Let the man speak for himself.

As it happens, I do like playing cards.

Yeah, but not the kind of cards she wants to play.

Honestly, Commissioner... In fact, everyone,

do not play cards with this girl.

Uncle Merv!

Was she just trying to hustle the Commissioner?

Yeah.

Welcome to my family.
