PANTING
DISTORTED VOICES
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. Oh, 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. "Oh!"
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.
Oh, 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.
INTERNAL RINGTONE
MOBILE VIBRATES
CHUCKLING
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!
Oh!
Sir... I can't see the resemblance, either.
MOBILE VIBRATES
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 11 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 died in the bunker?
Cool!
Not...not cool that he died, 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. Uh-huh.
I had a good sniff of the body
and there was a definite waft of almonds...
HE SNIFFS ..which means cyanide, right?
Definite signs of cyanide poisoning.
This mug of coffee could be a possible source.
SNIFFS 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 kill him?
What are you thinking, Sir?
I wish I had my own bunker.
Right, um, I meant about the case.
Oh, 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 18 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. Mm.
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 suicide.
If Kit was planning to go to the police,
then he had every intention of leaving this bunker.
Yeah, but if the poison that killed him was, as we suspect,
in the mug of coffee that he drank...
SNIFFS
..how and when did the killer 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.
HE SIGHS
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 killer got their weapon 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.
Oh, 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.
5,000 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.
INDISTINCT CHATTER
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. 60 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 30s, 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 M3.
Mm-mm, 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.
PHONE RINGS
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?!
SHOUTING OVER EACH OTHER
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.
HE SIGHS 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 killed Kit.
I just didn't, all right?
MARLON: We got a visit from the farmer
who owns a property adjacent to the preppers' place.
Mrs Clemenson said she heard gunshots being fired over
the commune, intermittently, over the last month,
in the woods on the east side.
Assumed they were hunting or shooting 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 weapon.
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 kill 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.
Oh, 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! Ah...
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.
HE SIGHS
I appreciate you speaking to me, Sir.
Thank you.
# Bam-bam ba-ba-da-ba da-bam-bam
# Bam-bam ba-ba-da-ba da-bam-bam... #
Oh, 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.
Oh, man!
What happened?
NAOMI: 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 assault rifles.
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 guns 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 weapon?
You just don't get it, do you?
The world if on a knife 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 guns?
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 kill 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.
HE CLEARS THROAT
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? Mm-hm.
I did not know that. Mm.
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 20 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.
Oh? 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 murder 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.
OCEAN SOUNDS PLAY 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.
Ah, 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.
Hm!
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.
Oh, 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!
SHE GASPS
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.
Oh, 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 burned 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?
MOBILE RINGS AND VIBRATES
Sorry.
Naomi. Everything all right?
Uh, I'd been having target practice.
Charlie was teaching me how to shoot.
He headed off and Luna had heard the gunshots,
so she came to confront me. GUNSHOT
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! GUNSHOT
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 murdered 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?
HE SNIFFS
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. Oh, erm, yeah. Yeah. Yeah. Thanks.
Sarge, Luna Jones' body is on its way to the mortuary.
At first glance, the bullet 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.
Ah... 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 murdered 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 killed Kit Martin,
but it doesn't explain why.
Mm!
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 knife edge.
It was you who persuaded everyone else that you needed guns.
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 suicide.
Could Kit have done this to himself?
You can't prove any of this.
Oh, you're very nearly right on that score,
Mr Banks, except, once we figured out exactly how the murder 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 murder 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.
HE SOBS
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.
Uh, 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 CLEARS THROAT
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...
WHISPERS: Wild card. HE CHUCKLES
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.
RUMBLE OF THUNDER
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 murdered?
Oh, you've got your Sergeant's training manual!
Who has ever read a book that is 482 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!
