12x02 - Episode 12

[bunniefuu]

I wouldn't lie to you, Kit.
Kit, we need you here. We need you.

Listen to me, that's it...
You've gone too far!

It's not what we agreed.
Listen to me, I'm done!

I made it to the bunker.
I'm safe, I'm secure.

No-one else knows I'm here.

But, um, it's the only place
I feel safe right now.

I just need some time to get my head
around what's happened here.

I've been so blind to it all.

But lately, this place has
just become so toxic.

I have to do something.

You got an address for us, honey?

OK. We'll see what we can do.

We've got a no-show at a courthouse.

A guy called Kit Martin.
Man, not that guy again!

You know him?

He's one of those crazies,
up at that weird cult in the hills.

I'm sorry, did you say "cult"?
Yeah, it's like a doomsday cult.

They all think the world's
going to end tomorrow.

I think the term is "preppers", Marlon.

Preppers?
People who make preparations to try

and survive a global disaster
or catastrophe.

Like I said, crazies.

Let's go.

You stupid thing!
Having fun, Charlie?

Not in the least.
Anything I can help with?

You know what? You can get on with
cooking us up a bit of grub.

Roger that.

Morning. Can I help you?

All right. Well, let us know when
you have an arrival date in mind.

Keep in touch. Is that the couple
from London? Yeah. I like them.

They remind me of us.
Or how we used to be.

Fed up and desperate
to do something with our lives.

Do you think they'll come?

The police are here.
They're looking for Kit,

who was supposed to
be at court this morning.

He never mentioned it.
It's just for a minor offence.

Do you know where
Mr Martin is right now?

I haven't seen him all morning.
Me neither.

His pick-up's in the drive,
so he must be here somewhere.

Let me try his mobile.

Text from Sophie.

I thought it might be. She's so funny.
We went to the zoo yesterday

and there was this giant
tortoise and she said

it looked like me. Look!

Sir...
I can't see the resemblance, either.

I do not look like a tortoise.
I never said you did, Sir.

Hi, Marlon. Um...

Er...

I'm up at the preppers' commune

and... we've got a dead body,
Inspector.

So, what do we know?

Well, none of the residents
had seen Kit Martin

since he went to bed last
night at o'clock.

When we arrived, Mr Martin still
was not answering his phone,

so we used a "find your phone"
app to locate him.

And where was his body?

The door was still bolted
shut from the inside.

Had to use that to get it open.

The victim was already dead
when we opened the door.

So, he d*ed in the bunker?

Cool!

Not... not cool that he d*ed, obviously.
That's tragic, but...

...you know.

Bunkers are cool!

Did he just say "bunkers are cool"?

Of course he did.

Paramedics reckon the body had been
lying here a good few hours

before it was found.

Cause of death?
Possible cardiac arrest, but...

...the red lividity on the skin here

could be caused by him
ingesting poison. huh.

I had a good sniff of the body

and there was a definite
waft of almonds...

...which means cyanide, right?

Definite signs of cyanide poisoning.

This mug of coffee could be
a possible source.

Huh.

Let's get all this stuff
to the lab for testing.

Make sure we check for cyanide.

Any other consumables in here
or about his person?

Nope, they've only just finished
constructing it,

so it's not stocked up,
just tea and coffee.

OK. Let's bag up this laptop.

We can start working through it
back at the station.

And we should check his phone
for recent activity.

Sir, looks like our victim

entered the bunker at eight minutes
past midnight last night.

Any other comings or goings since?

No-one else is seen approaching
the entrance until...

...just after one o'clock today
when we arrived. Huh.

So, Kit Martin makes his way
here into the bunker

in the middle of the night...

...locks the door behind him
and then dies of cyanide poisoning.

It's like something out of a spy novel.

Well, it leaves us asking two questions.

Did he take his own life?

Or did someone k*ll him?

What are you thinking, Sir?

I wish I had my own bunker.

Right, um, I meant about the case.

Er, yeah, sorry. Um...
Inspector,

DS Thomas,
I found this on the victim's phone.

No-one else knows I'm here. It's the
only place I feel safe right now.

I just need some time to get my head
around what's happened here.

I've been so blind to it all.

But lately, this place has
just become so toxic.

I have to do something.

I have to act.

It's time to go to the police.

Do any of you know what he's
referring to?

No. Doesn't make any sense.

So, why had it become "toxic" here?

I don't know why he'd say that. Yet,
the next morning he's found dead,

possibly poisoned.

Mrs West?

Could Kit have done this to himself?
Why do you say that?

Because he was prone to mood swings
and paranoia.

Um... He was inclined to...

He was a pothead.

That's what she's trying to say.

Nice lad, don't get me wrong,
but the kid liked a smoke.

He wasn't always clear-minded.

Sir, that's why Mr Martin was
due in court this morning.

Possession of a Class B drug.

Well, I've watched the video
footage twice through,

and I have to say,
he seems lucid and clear-headed.

How did you all know the victim?

We all met online on a preppers'
forum about months ago.

Justin and I were increasingly
concerned with the growing

threats that we're facing in the world,

so we just wanted to make some
significant changes to our lives.

But doing it on this scale,
I mean, setting up a new community,

that was a pipe dream
until Kit came along.

How do you mean? Well,
he had the capital to invest,

get the whole thing up and running.

We've all got so much to thank him for.

We wouldn't be here without him.

Well, I'd like you all to stay here
while we conduct a full

and thorough search of the property.

I'd also like to see the plans
for the bunker.

Marlon, Darlene, you know what to do.

I really am so sorry for your loss,
Mrs Martin.

We'll keep you abreast of any
developments as they happen.

Sir, just spoke to Kit Martin's parents.

They're pretty shaken up,
as you would expect..

Making any sense of it?

I'd say I'm making less and less
sense of it by the minute, Naomi.

I just don't believe this
was su1c1de.

If Kit was planning to
go to the police,

then he had every
intention of leaving this bunker.

Yeah, but if the poison that
k*lled him was, as we suspect,

in the mug of coffee
that he drank...

...how and when did the k*ller manage
to add the fatal dose?

He said himself,
no-one knew he was coming here.

Nobody else knows I'm here.

Yeah, puts paid to the notion
that the poison was

pre-administered in some way.

Then it must have been added during
or after Kit made his mug of coffee.

But we know it can't have been
because the security camera

footage shows that no-one entered
this bunker last night.

So, how did someone get
poison into that coffee?

Is there a secret way in,
or an escape hatch, or...?

Look, this bunker was designed
and built by Charlie Banks, and

he swears blind that the only way in
or out of here is through that door.

Inspector, Sarge,

I found this in a drawer in the
study. The drawer was locked,

but I used some of the old
Marlon Magic to get it open.

Acute toxicity.

These weren't factory-produced.
I spoke to the suspects.

They're cyanide pills
for the... worst-case scenario.

And they all knew about these?

Including Kit,
they were keen to point out.

At least now we know where our
k*ller got their w*apon of choice.

All right. Let's get this stuff
back to the station.

Nothing more we can do now
until the postmortem results

come in tomorrow morning.

No!
I didn't realise that was the time.

You two got plans again?

Yeah, there's this creole restaurant
in the hills that she wants to try.

We're trying to
squeeze in everything

we can before she flies home.

Hello! Hey!

How was your day?
Yeah, it was amazing.

Went to that secret beach Catherine
told me about. How about you?

Equally good. I only
went inside a real-life bunker!

If they already
know about the cyanide,

this doesn't end well for us,
does it?

Morning, Sir. Morning, Naomi.

How was your dinner last night?

It was... all right.

I've never really had much
creole food before,

but I didn't dislike it,
on the whole.

That's great, Sir.
For you, I mean.

It can be really spicy sometimes.

It's just Sophie,
she's so adventurous.

We're actually hiring
jet-skis later.

Well, that's something I thought
I'd never see!

It's a shame she's leaving so soon.

Do you think you guys will
keep in touch?

Maybe visit each other? Honestly?

Probably not.

, miles. It's not exactly
a hop across the Channel, is it?

It's... it's fine. We knew what the
deal was. We're both cool with it.

The, um, postmortem
and lab report were emailed over.

Kit Martin's death was definitely
caused by cyanide poisoning,

between six and seven o'clock
yesterday morning.

And was the poison in his coffee?
Yep.

No-one else's fingerprints
were on the mug

and he hadn't consumed anything else
since dinner the night before.

No traces of cyanide in the coffee
granules or the bottled water,

so the poison had to have been added
after Kit had finished

making his coffee. But how?

He was locked in that
bunker, on his own, all night.

I know there are people who think
preppers are selfish, we're

just looking out for ourselves,
but that's not what we're about.

We're growing our own,
got our own electricity.

By the end, we're going to be
completely self-sufficient.

I mean, this place is just...

It's beautiful.

So, what we've got here are some
sweet potatoes... What is this?

It's a yam? A yam. Check that out.
We've got a nice yam. mil.

Fellas, we're going to need a bigger
tape measure. We've got a big yam!

Whatever calamities hit us,

be it a global financial collapse
or an EMP solar flare,

our role will primarily be working
with local communities, helping them

to rebuild society.

It's not about protecting ourselves.

It's about preserving
all our futures.

Wow! He really cared about what
he was doing.

Had a real vision.
What else do we know about him?

He came from a very rich family,
by the looks of it.

They made their money in textiles
back in the UK,

but Kit decided to tread
a different path.

Sold off his stake in
the business to pursue

a more "community-focused"
way of life.

Hence his investment
in the preppers" commune.

And what about his laptop?

Interestingly, Sir, everything,
and I mean everything,

had been wiped from it.

But we've sent it up to the
lab to see what they can recover.

OK, well, let's talk about
his fellow preppers.

Raya West seems to be the driving
force, founding the commune.

In her s, she started working
for an environmental charity.

It says here she was recently
arrested at a fuel protest for

glueing herself
to a traffic bollard

on the Basingstoke turn-off
of the M .

Now that is a woman you
really would not want to mess with.

You know Basingstoke is home
to the

largest banana-ripening
warehouse in Europe?

Why do YOU know that, Sir?

I don't know.
What about her husband, Justin West?

He was a geography
teacher at a school in Reading,

right up until he
and Mrs West left for Saint Marie.

And that just leaves this guy,
Charlie Banks.

Ex-Army, worked across the world on
humanitarian aid projects.

He's the only member of the commune

to have hands-on
experience in real-life disasters.

Also, he's in a lot of Kit's vlogs.

They seemed to be good friends.

They share a real
vision for the commune.

Trainee Officer Darlene Curtis
speaking.

It's Marlon. He's with Jarrell,
the owner of the hardware store

near the harbour.
He's got something for you.

Sir, Sarge,
when we searched the commune,

I found a number of invoices
from Jarrell's shop.

It seems the preppers use it
a lot for their hardware supplies.

The thing is, according to Jarrell,
the day before yesterday, Kit Martin

and Justin West came down to pick up
some timber and, well,

there was a pretty old bust-up.

Between Kit and Justin?
Poor Jarrell had to break it up.

You've got it all wrong.
I know what you're up to.

I wasn't born yesterday!
You're paranoid, mate!

There's nothing going on!

Did he say what it was about?

Justin was warning Kit to
stay away from Raya.

Just keep your hands off her,
all right?!

I... never intended to lash out.

I just wanted to talk about it with
Kit, away from this place.

What led to the argument, Mr West?
His denial of the affair,

the suggestion
I was just being paranoid.

All of which is true.

Look, Kit and I were close.
We were friends,

we spent a lot of time together.
You know, he was a good listener.

But there was absolutely nothing
else going on between us.

Apparently,
you felt differently, Mr West.

Sometimes it's easier to blame
marital problems on an outsider,

rather than to
take responsibility oneself.

Justin doesn't believe in
what we're doing here.

He thinks it's a cop-out.

Those are your words, Raya.
Well, use your own.

To me, it all seems too fatalistic.

We're all going to
hell in a handcart,

so let's just save ourselves.

You know that's not what this is.

So, how did things resolve
themselves? I apologised.

To Kit. After Raya put me straight
about what had been going on,

or not going on.
Still sounds a bit begrudging.

Maybe,
but it doesn't mean I k*lled Kit.

I just didn't, all right?

We got a visit from the farmer

who owns a property
adjacent to the preppers' place.

Mrs Clemenson said
she heard g*nshots being fired over

the commune, intermittently,
over the last month,

in the woods on the east side.

Assumed they were hunting
or sh**ting vermin.

I ran a check and none of our
suspects are licensed to own

firearms, either here on Saint Marie
or back in the UK.

Which means they're potentially
in possession of an illegal w*apon.

Yeah.
We should talk to them about it.

But none of this brings us
any closer to understanding why

one of these three suspects felt it
necessary to k*ll Kit Martin.

Or how they did it. Exactly.

Kit fled to the bunker
and locked himself in.

No-one knew he was going there,
so the poison couldn't have been

already planted, and no-one
visited him while he was inside.

And yet, one of them managed to get
poison into a mug of coffee

Kit made himself while safely
secured inside the bunker.

Let's just leave it till tomorrow,
see what a fresh day brings.

Sir? Are you and Sophie still going
jet-skiing this evening?

I'm sorry, what did you say?

The Inspector
and Sophie hired jet-skis.

Man! This I have to see!

What...?
Why do you say it like that?

Well, you know, Sir, the thought
of you on a jet-ski, it's... What?

It's funny. I mean... Marlon. Yes?

I forgot to mention, the
Commissioner called.

He wants to see you.
But I'm going to miss all the fun.

Sir, I don't suppose you could push
jet-skiing to tomorrow?

Yes?

No? Maybe?

Maybe.

Agh!

Evening, boss man.

"Evening, Commissioner."
Evening, Commissioner.

That's better.

Please... sit down.

So... what can I do for you, Sir?

I received the application
forms you completed.

You've decided you want to apply
to be a Sergeant?

Well, I figured I've got this whole
officer thing pretty much licked,

so let's take this ride
to the next level.

Right?

Is there a problem, Sir?

Did I not fill it in correctly?

You know how impressed I've been
over the last two years

by the way in which you've grown
and developed as a police officer.

But, and I'm going to
speak candidly now...

...I do not think you are ready
to take this next step.

The role of a Sergeant brings with
it much greater responsibility

than I think you anticipate.

But I...
I worked with JP, though, Sir.

And DS Thomas
when she was in uniform.

I know what the job entails.
And the reason they were both

so good at it was that they had
a fair few years' experience

behind them before they did it.

You were still just a trainee
police officer up until a year ago.

I've no doubt, in time,

you will be able to
study for your Sergeant's exam.

But, um...

...not just yet.

I appreciate you speaking to me,
Sir.

Thank you.

Man!
What's the Inspector done now?

Hey. What happened?

Inspector Parker OK?

Neville is fine. Really?

But she's not. Poor dear.

I'm really, really sorry.
I'm so sorry. It's fine.

Don't worry about it. It's all
a part of my Caribbean adventure.

Man!

What happened?

He accidentally reversed
his jet-ski into her jet-ski.

Knocked poor Sophie right off.

Well, is the jet-ski OK?

I... I mean...
How did he manage that?

Neville saw a huge jellyfish.

And he got scared. Of the jellyfish?

Well, he panicked
and tried to swerve away from it.

Hey, Sir. Naomi.

Is Sophie all right?
They've taken her for a scan,

but they're not worried,
so, fingers crossed.

And are you OK?

Am I just, like,
the biggest idiot ever?

Well... not the biggest.

Er, so...

...there's been a development
in the case I thought you'd

want to know about. OK.

We received a call from Kit Martin's
brother, Alex. Right.

And the last time they spoke,
about a week ago, Alex said Kit

and Charlie Banks had been good
friends, but recently fell out.

Why? Over the fact that Charlie had
been bringing firearms into the

commune, and by the sounds of it,
we're not talking for hunting, Sir.

Kit said Charlie had brought in
a number of as*ault r*fles.

That's some serious firepower.

Morning, Inspector.
Hi. How's Sophie?

Better, but they want to keep her
in another night, just to be safe,

which isn't great because it's her
last night on the island.

Inspector...

...with the greatest respect,

you are just the worst boyfriend.

And I should know cos I have dated a
couple of real stinkers in my time.

You know, you've got
some serious making up to do.

Yeah, I know, Darlene.
I'm working on it.

You want to show me the spoils?

Morning, Sir.

Looks like Kit was right.

Found these hidden behind some
junk over there.

I don't understand. I mean,
why would they need g*ns like that?

Because when it's every
man for himself,

I don't intend on
taking any chances.

And what exactly do you envisage
happening that would warrant

arming yourself with that
kind of w*apon?

You just don't get it, do you?

The world if on a Kn*fe edge,

economically, environmentally.

When disaster strikes, there's going
to be serious civil unrest,

but trust me, I know how
desperately ruthless people can get.

So those are for your own
protection?

We're entirely self-sufficient here.

But when the shops run out of food
and the electricity gets turned off,

where do you think everyone's
going to flock?

And when it all hits the fan,

the only people
I'm looking out for

are my people. That's not how
Kit saw it, though, is it?

He had more noble
ambitions for this place.

Kit and I, we were mates,
we shared the same opinions,

but he could also be
naive about certain things.

Is that why
he had to be dispensed with?

Cos he was going to tell
the police about those g*ns?

I had no idea that's what
he was planning to do.

I knew Kit
and I weren't getting on any more,

but he never told me
he was going to the police.

And if I didn't know that,
then why would I k*ll him?

We'll be confiscating those weapons.

In due course, you'll be charged
with illegal possession.

He's quite an intense man, isn't he?

Crazies. Each and every one of them.

Morning, Commissioner.

Everything all right?

Morning, DS Thomas.

Um...

I wondered...

...if Marlon mentioned to
you that he'd applied to

take his Sergeant's exam.

He did?.

I did not know that..

I recommended he get a few more
flying hours under his belt first,

which he seemed to take on the chin.

I thought a little pastoral care
from a senior colleague,

and friend, wouldn't go amiss.

I'd hate to dent his confidence.
I hear you, Sir.

I'll keep an eye on him.

Although, Marlon's confidence
is pretty robust.

Morning, Sir.
You looking for me? Nope.

OK.

So, the lab returned the laptop
we found at the crime scene.

The good news is they were able to
recover most of the data wiped

from the hard drive and it turns out
this isn't Kit Martin's laptop.

The administrator name is
registered as Luna Jones.

Luna Jones?
This is her social media page.

Until last year,
she was a student in the UK,

studied global ethics
and graduated last summer.

Email history? Unfortunately,
they weren't able to recover it.

Interestingly, there is

a research and a dissertation
on preppers' communities.

Any connection between her
and the victim? Just this.

A picture taken of her
at the commune.

Is there a time stamp on that photo?
Yes.

Four weeks ago.

So, how did Luna Jones' laptop end
up in Kit Martin's possession

when he was discovered
dead in the bunker?

Luna was a resident
here for a short time.

I mean, she left
just under a week ago.

Before you ask, no, there was
no ill feeling between any of us.

Why did she leave
so soon after she'd arrived?

Just wasn't for her, I think.

In what way?

Well, Luna was years old,
you know,

she had no life experience,

very privileged upbringing.

I think just being here,
the isolation

and the hard graft just wasn't
for her. She struggled with it.

You know
how young people can be these days.

No. But I'd love for you to tell me.

Well, not all of you, I'm sure,

but, you know, snowflakes,

isn't that what they call them?

Look, Luna couldn't hack it
any more, simple as,

so she upped and left,
there's nothing more to be said.

Well,
there's a little more to be said,

specifically about this laptop.

Why did Kit have it?
I've no idea.

Or why he wiped it.

Luna must have forgotten it.

By mistake.

Left it behind. You know.

Yeah,
that's what must have happened.

We'll see ourselves out.

OK, so the firearms are now
with the National Guard.

They said they looked pretty dodgy,
unsafe.

Not entirely surprising. They were
obviously acquired illegally.

Sir, I just spoke
with Luna Jones' mum.

She's not heard from her since
she left the UK over a month ago,

but that's not unusual, apparently.

Sounds like she's quite
the free spirit.

Immigration records show her
arriving on the island

but not leaving,
so she's still here.

There's something they're not
telling us.

OK, I want to put the house under
surveillance, tonight.

Anyone got a problem with that?

Well, I might have a small problem
with that, Inspector Neville Parker.

Are you going to work all night
while that sweet girl of yours

spends her last night
on the island in hospital alone?

I... I hadn't really thought...
I mean, I...

Sir, I think Trainee Officer Curtis
maybe has a point.

You really should be with Sophie.

But I can't ask you all to do this
while I just go and...

Er, yeah, you can.
I reckon we've got this.

Yeah, maybe don't take her
jet-skiing, though.

You know...

Here you go.

Thank you.

Doesn't look very appetising,
does it?

Aren't you supposed to be
investigating a m*rder case?

Yes, I am, but I've been stood
down by my junior officers and given

strict instructions not to leave
your bedside till the night is out.

They're a good lot, your team.
Yeah, they are.

Look, I'm sorry that this is how
we have to

spend our last night together.
Hey, it's fine.

Anyway, we were only going
to Catherine's Bar for a last meal,

it's... I know, but
Catherine's Bar's where we had our

first meal together.

Which is why I thought...

Andreas?

...if we can't go to
Catherine's Bar, I thought

maybe I could bring
Catherine's Bar to you.

She said you might need this.

What's going on?

All done.

You OK? Yeah. I feel fine.

Bonsoir, Sophie. Catherine!

My chef has prepared your favourite.

And somewhat reluctantly,
your chicken and chips. Excellent!

And here is a cocktail
I have created in your honour.

I call it the Kiss of the Jellyfish,

after your encounter last night,
Neville.

And also because it's got
real zing in it. I found this.

Sounds of the Ocean, to get the
full Catherine's Bar experience.

Now, a good hostess always knows

when to give her customers
some space.

So, enjoy your evening.

Thanks, Catherine.

Thank you. My pleasure.

So, am I forgiven?

Just about, yeah.

Darlene, any action on your end?
No, Sarge. Not a peep.

All right, let's stay in contact.
Okey dokey, Sarge.

I mean, received. Sorry, hon!

You're quiet.

Not like you.

Just thinking the case over.

Who did it, how, etc. Right.

Any theories?
It's a work in progress.

So there's nothing you
want to talk about?

Nothing on your mind? Like?

I don't know. You tell me.

The Commissioner spoke to you,
didn't he? He might have.

But only cos he cares about you,
same as me.

You're not too disappointed?

A bit, I guess, but the Commissioner

isn't usually wrong about much,
so...

It just makes me wonder if I'm
doing as well as I thought I was.

Marlon, you mustn't think like that.

You're doing so good

and we're all so proud of you.

You bring skills to this
team that we just don't have.

You're like our wild card.

For real? For real-real.

You know, I've never been called
a wild card before.

I kind of like it. Good!

Wild card.

Sarge, I've got some
movement down here. It's Raya West.

She's left the house and heading
for the pick-up truck.

She's looking for something.

It looks like she's grabbed
a spade and some sort of tarpaulin.

She's coming this way, Sarge!

OK, Darlene, you need to tail her
and stay out of sight.

Lord! Help me now!

I know a short cut that will
get us close. OK.

What's she doing? It looks like
something's already buried there.

Or someone.

Police!

Mrs West, stop what you're
doing and step away! Now!

I said step away, now!

You need to tell me
what's buried there.

Mrs West,

we're going to find out.

You might as well tell us. Now!

It's Luna.

I'm sorry.

It was an accident.

I didn't mean for it to happen!

So, I guess the first thing I'll do

when I get home
is stick the heating on.

I forgot all about central heating.

All right! Don't rub it in!

But I did!

So, when I do go back home to
Manchester,

do you reckon we'll stay in touch?

The elephant in the room, huh?

Well, one of us had to ask.

I've thought about little else,
to be honest.

And I really, really love
spending time with you.

But...?

It wasn't that long ago
I got quite badly b*rned by someone.

You never said.
Something and nothing, really.

She's not even on the island
any more, but...

...I really like you.

But the whole long-distance thing...

...I just wonder if we're
better off saying our goodbyes now,

instead of being hurt
more in the long run.

You know?

I guess living in paradise
does have some drawbacks, hey?

Sorry.

Naomi. Everything all right?

I'd been having target practice.

Charlie was teaching me
how to sh**t.

He headed off
and Luna had heard the g*nshots,

so she came to confront me.

Raya?

About what? She was angry.

This is all wrong!
Things have to change!

She didn't like that we'd
brought weapons in.

She said it wasn't what this place
was supposed to be about.

It wasn't what Kit envisaged.
So you argued?

She said I was clearly having
some sort of midlife crisis.

What are you talking about? Bringing
weapons here! Flirting with Kit!

What?! You're just pathetic, Raya!

She said there was something
missing from my life,

and I wasn't going to find it by
running away to the Caribbean.

And you're dragging this place and
the rest of us down with you! Luna!

I guess she touched a nerve.

Luna!

So, after that, you buried the body?

I knew Kit was digging an irrigation
ditch and I just... I just panicked.

I dragged her body and I...

...I pushed her in.

And what about Luna's possessions?

I drove back to the house,
gathered her things

and dumped them in the skip.

And then, later that evening,

I told everybody that she'd
decided to leave.

Charlie and Justin, they...

...they wasn't surprised,

but Kit thought it was odd that
she left without saying goodbye.

And then he found the laptop.

I wiped it, but in the rush to get
rid of all her things, I left it.

And Kit confronted you about it?

I tried to convince him that there
was nothing suspicious going on,

but he just didn't believe me.

I'm not telling lies! No, you are
lying! I can see it in your eyes!

Luna wouldn't just forget this!

He said he wanted to leave
the commune,

withdraw the funding.

He said that

we'd destroyed something good.

I think that's when he must have
gone back to the bunker.

So, in the interim,

to stop Kit from going to the police
with his suspicions about what

happened to Luna, you m*rder*d him?

No.

It wasn't me.

Why should we believe you, Mrs West,

after everything that's happened,
after all the lies you've told us?

Because seeing Luna's body there,
I could never do that to anybody.

It was an accident!

I don't know about you, but I just
feel like Mrs West is telling

the truth when she says
she didn't poison Kit Martin.

Yeah. I kind of agree with you, Sir,

which means that leaves us
with just two suspects -

Charlie Banks... and Justin West.

Neither of whom had any idea that
Kit was going to be

in the bunker that night.

Or, according to security camera
footage, made any attempt to

enter it after he'd gone in.

And yet, somehow, one of them
managed to poison him, despite

the fact that he was locked in
there, supposedly safe and sound.

But which one was it?
And how did they do it?

Something wrong with your coffee,
Sir? Is it the milk?

Has it gone off?

It tastes all right.
No, it's not the coffee, Naomi.

We've been thinking about this
all wrong!

That explains it!
You think you've got it? Yes!

No, some of it, but we need to get
back to the crime scene. OK.

Er, Sir? Yeah?

Maybe I should take that.
erm, yeah. Yeah. Yeah. Thanks.

Sarge, Luna Jones'
body is on its way to the mortuary.

At first glance, the b*llet wound
tallies with Raya West's account.

Thanks, Marlon.

What's he doing down there?

Not really sure.

Er...

He keeps checking
the security camera,

then every few seconds, pops inside
and then pops back outside again.

See? There he goes.

Maybe we should go inside and
see if he needs a hand.

And he's back out again.

The only way to get poison into
this bunker is through the door.

So that's what must have happened.

Of course!

Of course, of course, of course!

That's how it was done!

Had to use that to get it open.

No-one else is seen
approaching the entrance

until just after one o'clock today
when we arrived.

We'll keep you abreast of any
developments as they happen.

Sounds like you've got it,
Inspector.

Yes, I have, but we're going to need
to do some dusting for fingerprints.

I'll get the crime kit, Sir. Marlon,
I'm going to need one more thing.

What's that? A cup of tea -
milk, two sugars, nice big mug.

They're waiting for you inside,
gentlemen.

Gentlemen, please, take a seat.

Now, one of you two
m*rder*d Kit Martin

by adding a fatal dose of cyanide
to a mug of coffee he drank

while he was locked inside this
bunker, alone, only a few days ago.

The question we've been asking
ourselves ever since is,

just how did you manage to
spike his coffee with poison

when we know from the security
camera footage no-one else

entered the bunker during the time
he was down here?

And nor could you have
pre-administered the poison

so it was there waiting for him

because Kit's visit to the bunker
was spontaneous, so you

couldn't possibly have known he
would end up locked inside.

So, how did one of you manage to add
that fatal dose of cyanide

to his drink?

Well, don't look at me.

Charlie?

You think it was me?

This, I can't wait to hear.

OK. Er,
perception is a curious thing.

When we first entered the
crime scene and found Kit with a

half-drunk mug of coffee,

we assumed that he must have made
it here in the bunker, himself.

But what if Kit didn't make
the coffee himself at all?

What if it was brought to him
with the poison already added?

We know that you designed
and built this bunker, Mr Banks,

so, of everyone, you know
it inside and out.

And that's why you
knew that there was a

blind-spot in the view
from this security camera.

Because the camera is mounted
above the door and points outwards,

it does not actually show
whether or not the door,

which swings inwards,

is open or shut.

Marlon, you ready? Ready, Sir.

And if someone should lay on top of
the bunker, above the entrance, they

could pass something down to whoever
is inside without it being

caught on camera, just like that.

So, that explains how you k*lled
Kit Martin,

but it doesn't explain why.

On the night that Kit
entered the bunker,

you must have overheard him arguing
with Raya.

I'm not telling lies!

No, you are lying!
I can see it in your eyes!

We know Kit told Raya
he was done with the commune

and he was withdrawing his funding.

Listen to me! I'm done!

That's it! I'm phoning the bank
and I'm closing down our account!

I'm taking my money back! Kit!

And that's when you
started to worry, big time,

because without Kit's money,
this place shuts down.

And the commune mattered
more to you than to anyone else

because despite that tough
demeanour, you are scared.

You're terrified -
about the world, about the future,

about what could very possibly
happen to this planet.

The world is on a Kn*fe edge.

It was you who persuaded everyone
else that you needed g*ns.

It was you that built the bunker.

This commune was your haven,
and no-one was going to take it

away from you. That's why
when Kit locked himself in here,

you realised if the commune
was going to keep going

that he could never leave this
bunker alive.

And so, early the next morning,
you made a mug of coffee

and added poison to it.

Now, we know that despite the
thick steel door which keeps

whoever may be inside here
away from the outside world, it is

still possible to communicate.

And that is what you did.

You spoke to him.

You reassured him.

Even though we can't possibly
know what was said,

you will have persuaded him that you
were on his side.

I get it, mate.
Things have got out of hand here.

I'm as worried as you
are about Luna.

Kit was in a... in a state.

He suspected Raya was lying to him,

he was fearful about what might
have happened to Luna,

he was tired, isolated,
desperately in need of a friend.

And that's what you
convinced him you were.

Things should never have
come to this.

You're right about us messing it all
up. I'm so sorry, Kit, I really am.

I made you some coffee.
You must be shattered in there.

Get some caffeine in you, mate,
and you'll feel much better.

Then we can sit down
and talk about this properly,

face to face, sort it out,
get things back to how they were.

Kit, open the door.

OK, but don't come in, all right?

I'm going to open the door.
Do not come down the stairs, OK?

Here you go, mate.
Careful, it's hot.

Kit brought the
coffee back inside...

...removed the spoon,
placed it on the table...

...and drank it.

You knew
when we arrived at the crime scene,

with nothing to suggest otherwise,
we'd assume that Kit made

the mug of coffee himself and then
therefore think it was su1c1de.

Could Kit have done this to himself?

You can't prove any of this.

You're very nearly
right on that score,

Mr Banks, except, once we figured
out exactly how the m*rder was

carried out, we were able to
dust for fingerprints

in places we would have
otherwise not thought of.

The door frame
by the security camera.

And we found only
one set of prints with

residual traces of a white
substance, cyanide.

Your fingerprints, Mr Banks.

Charles Banks, I'm arresting you
for the m*rder of Kit Martin.

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

if you do not mention
when questioned...

Inspector?

Is there any word on Raya?

What's happening to her?

She's been charged
with manslaughter.

I'm afraid you'll have to speak
to her solicitor

if you want any further information.

I'm sorry.

Good day, Mr West.

Out of the jeep, please, Mr Banks.

Inspector, I was just passing,

I wanted to congratulate you on
solving the case. Thank you, Sir.

I couldn't have done it without
these guys' help.

They've been particularly supportive
these last few days.

I've had a few things going on.

Yes, I heard there was an incident
with a jellyfish?

Yes, Sir. There... there was.

On which note, Sophie's boat
leaves in, like, two minutes.

Do you guys mind if I...?
Of course. Thank you.

Commissioner, Sarge.

You OK to take it from here? Yeah.

Um...

I just wanted to thank you
both for giving me some advice.

I know it might have
come as a bit of a surprise,

me applying to be Sergeant.

Your ambition is admirable,
Officer Pryce,

if a little premature.

Yeah, the thing is,
though, about that, um,

I've been doing some
thinking about the whole thing.

And I'm still going to do it.

It was actually something that

DS Thomas said that got me thinking.

She said that I'm a wild card, and
she's right. I always have been.

Hustling on the streets, taking
any chance where I can get them.

I know that I can knock the
Sergeant's exam

right out of the park, so...

Wild card.

Hey! You made it!

Well, I couldn't not see you off.

Not that I'm particularly good at
this sort of thing.

Well, me neither.

Listen...

...thank you for making the last
few weeks so much more lovely

and special than I thought
they could be.

I've had the best time with you.

Right. And thank you for your
general sense of...

...patience and tolerance,

which was particularly tested

when I ended up literally
hospitalising you.

It's all part of the adventure,
right? Yeah.

Bye, Neville.

Bye, Sophie.

St Agatha's Cove is
a local beauty spot.

It can't be for sale,
I'm sure of it.

They were being conned. Have we any
idea why one of them was m*rder*d?

You've got your Sergeant's
training manual!

Who has ever read
a book that is pages?!

You're missing Sophie.
I think that ship has sailed.

We have three suspects,
all of whom have credible motives,

but each of them
also has a credible alibi.

They know nothing!

Darlene, he's heading out the back!

We have eyeball on our target.
Go, go, go!
