Death In Paradise (2011) s09e06 Episode Script

Murder on Mosquito Island

Listen up, chaps.
Tomorrow morning, I'm leaving you to fend for yourselves for two whole days.
I'm ready to rock and roll, Wolfie.
It's what we're here for, isn't it, love, the full survival experience? UNENTHUSIASTICALLY: Yeah, definitely.
Can't wait.
Malc? Case? Oh, well up for it, Wolfie.
HESITANTLY: Yeah, feeling, you know, ready.
You'll need to work as a team.
You'll need a strong, smart, committed leader.
So drum roll, please.
PATTERING Louder! Brrrr! Your new team leader is .
Oh, no.
Oh, I don't No, I don't think I'm really ready for this.
I Don't doubt yourself, Malcolm.
I have seen your fighting spirit over the last five days and I have absolutely no doubt you'll be fine.
You all know what you have to do, so let's get to it.
It's day five of Desert Island Casey, and things are getting tense out here.
Last night, it all kicked off big style.
WILL: Casey! Coming.
SIGHS Sounds like Major Moody's on the prowl so I'd better say ta-ra! THUD Stay still! Yeah! Yes! Yeah! Bravo! I got it! Ah! Couple of days ago, you wouldn't even touch a dead fish, now look at you.
Yeah, for our next holiday, Dave, you're going to have to make it up to me.
Guys, I'm heading up to check the traps.
Don't you need a pointman? No, won't take long.
I'll be back before lunch.
Aw! Mm! Taste lovely, that did.
Yeah, it was good, that.
It wasn't bad, was it? Shouldn't Will be back by now? I don't know.
I tell you what, I'll go look for him, huh? Hone my tracking skills.
Wolfie! Are you there, mate? What are you doing? Wolfie! Will, you all right? What? I'm not so sure about this, DS Dumas.
Well, we need a senior detective to lead the case.
I know, I know.
BANGING I just wish it didn't have to be that senior detective.
He's pretty good at it, no? Mm HAMMERING Inspector Parker.
What are you doing to my shack? I'm just making a few, er, home improvements, sir.
This place is a bit of a magnet for mosquitoes.
I'd appreciate you seeking my permission before you set about any renovations.
I just have a bit of a hypersensitivity to mozzie bites, sir.
I think it's my Type-O blood.
Um How have you been feeling the last week, after your collapse? OK, sir.
Thedoctor says just carry on as normal, keep wearing the compression socks.
In a few weeks' time, I'll be out of here.
Why? There's been a murder.
A man has been stabbed on one of the smaller islands near here.
Ile Saint Felix.
And we were wondering if you might be OK to take, er, one more case for us.
Actually, yeah.
I'dI'd welcome the distraction.
I'll just pack my stuff.
There's a helicopter waiting to take us over.
Cool! Where is this Ile Saint Felix? Ten miles off the north coast.
The locals call it Mosquito Island.
Very funny, sir.
Afternoon, JP, Ruby.
You ready? The journey shouldn't take long.
The victim is William Arnott, sir.
British ex-Army.
Worked as an instructor for a survival course.
Any witnesses? No, it seems not, sir.
He left camp and his body was found in the jungle.
They are saying the killer must have been an intruder to the island.
Dave Hammond.
It was me who made the call.
Did you find the body? Yeah, but I didn't touch him.
I saw him lying there, I went to check on him It's OK.
Just show us where it is.
Why don't you head back to the camp, Mr Hammond? Right.
Ruby, photos of the body, please.
JP, perimeter search of the crime scene.
I'm on it.
Initial examination shows the weapon used punctured the lower central abdomen .
so I can only assume he must have bled out.
Wound is approximately 1.
5cm in diameter, and almost circular, so it can't have been a flat blade used.
It must have been something else.
Sir! We got something.
Just here The grass has been trampled.
And look.
Footprints, but the sea's washed most of the details away, sir.
We've got one set leading from the sea up into the forest.
And the other one heading back.
So the intruder might have arrived by boat and moored here.
Headed into the forest and then committed the murder.
And then left the way they came.
Yeah, you'd think that's what happened, wouldn't you? Now, we know that, when a foot presses down on a blade of grass, it'll flatten it in the direction of travel.
Like so.
So even if our killer used the same route twice, most of the damage would happen on the first trip.
Yes, because on the way back, he would've gone over the ground that he trampled on.
Now, if SNEEZES Bless you.
Bless you.
It's my rhinitis.
It's just the pollen.
So You OK? So, because most of the trampled grass here is pointing towards the beach, that means that whoever created this path stabbed our victim in the clearing, went to the beach first, and then came back.
So the killer didn't arrive by boat? Exactly.
I think someone staged those footprints on the beach to look like there was an intruder when there was no such thing.
We arrived on the island five days ago.
Will's been training us up in preparation for a couple of days here on our own.
He's taught us everything.
How to build shelters, start fires, hunt, fish Yeah, proper back-to-nature, you know.
No phones, no booze, no fun.
Wait, no phones? So, how did you make the emergency call? On Will's satellite phone.
Would you mind walking us through what happened today? Well, this morning, we all split up to go and do our daily tasks, so me and Case were down by the river, getting water.
I was, uh, getting coconuts.
And I was with Wolfie, fishing.
Wolfie? Yeah, it's his nickname.
Got it in the Army.
Once you'd completed all these tasks, what then? Erm, we started to get lunch ready.
Will came back to camp, filled up his water canteen and then set off to check the traps.
WILL: I'll be back before lunch.
He said he'd be back in time to eat, buthe wasn't.
So I went to check he was OK.
That's when I found him.
And between Mr Arnott leaving the camp and you finding his body, Dave, did anyone else leave the group? At all? And did any of you know the victim before you arrived here? No.
How were things between you and Mr Arnott? Any fights or arguments? It was fine.
Yeah, we got on .
really well, didn't we? Yeah.
Why are you asking us that? Are you saying you think one of us did it? Let's just say we're not ruling it out.
SCOFFS But that's impossible! We were all here when it happened.
What are these? Spears for fishing.
One of the first things we learned.
You all made your own? Well, Will knocked us one up, and then we all made our own, yeah.
I don't know if you know this, but Ian Fleming was something of an accomplished spear fisher.
What's that got to do with anything? The tips of these look like they match the wound on Mr Arnott's body.
And there's only four of them.
Anyone know what might have happened to number five? JP HUMS CHEERFULLY JP, what is up with you today? Me? Nothing.
Why? Well, I mean, you just seem so happy.
Listen to you, humming a tune to yourself.
Well, it is mine and Rosey's wedding anniversary.
Ah! Happy anniversary, JP! Thank you.
So, what have you got planned? I've got some home-made rum punch chilling in the fridge.
Mm! And I've made reservations at Rosey's favourite restaurant.
Then we'll see what happens from there.
Oh, no, we need to hurry up to make sure that you can get back on time.
Oh, it's fine.
The reservation ain't till 8pm, so should be good.
But have you left time for the shower, the ironing of the shirt, the cleaning of the shoes and the brushing of the teeth? You know, I didn't think of all of that.
Men seldom do, JP.
But don't worry .
Ruby's got your back.
I've checked the route between here and the camp, and no sign of the missing spear.
I mean, it could be anywhere.
Most probably lost to the sea.
But the fact that they used one of the spears only confirms for me that one of those four must have killed Will.
MOSQUITOES BUZZ So it begins, mosquito witching hour.
HELICOPTER OVERHEAD Are we supposed to be on that? Well, JP and Ruby are heading back to the paramedics.
They are sending a boat for the rest of us.
How long will that take? The sooner I get off this island, the better.
Anything else of interest? Huh? Oh, yeah.
Uh, the sat phone, there were two emergency calls made.
Two? Yeah, one today to report the murder, but there was another one made last night.
What? Mmhm.
If the cops are thinking it's one of us, maybe they're right.
We all saw what happened last night.
If you're with me, I think we should tell the police.
Stick your hand up.
Hmm? The call was made by a man in distress.
The operator said that he sounded frightened, saying he had to leave the island before someone found him.
Then the line went dead.
Why wasn't the call put through to us? Well, when she called back, the same man said it was a joke that got out of hand.
She logged it and left it like that.
Did she get the caller's name? No.
It was Malcolm.
He made the call.
It was nothing.
Well, it didn't sound like nothing from what Dave just told us.
Well, I was scared.
I didn't know what he was going to do.
Will? SIGHS Look, last night I went to the loo, and mymy torch died on me.
It was pitch-black, I got lost and I guess I freaked out, panicked.
MOSQUITO BUZZES I didn't know where I was, I couldn't I couldn't see anything.
And then Will found me.
And I don't know why, but he just flipped.
You won't even stand up for yourself.
He'd been drinking.
He had a bottle shoved away.
We all knew.
So you stole the sat phone? I just wanted to get off this island.
But he caught you making the call.
And he was angry at first, but then he started fretting about what it was going to look like if people knew what he'd done, so he begged me not to tell anyone, that he really needed this job, it was all he had.
So youyou did as he asked.
Malcolm, are you OK? ANGRILY: He's absolutely fine.
Go back to sleep! Now! My ex-wife always said I was too sensitive.
That's why I came out here, you know, to toughen up.
And still, people treat me badly.
You think I killed him.
Did you? LAUGHS I couldn't defend myself in a fight.
You really think I am capable of murdering another human being? Why would anyone pay good money to send themselves to this hell-hole for a week? No accommodation, no food, no toiletries.
Would you do something like this? Maybe.
To challenge myself.
Then I think you're as barmy as the rest of them.
Not everyone likes to live in their comfort zone.
Well, I MOSQUITO BUZZES PHONE BEEPS Why can't they just leave me alone? JP and Ruby landed safely.
Do you get a signal here? One bar.
Only in this spot.
Let's go.
I'm telling you, Inspector, I haven't got a phone on me.
We had to hand them in.
And yet, you spent a lot of time in the one exact spot on the island where you get a phone signal.
Oh, DS Dumas? Mmhm? Would you search her, please? Of course.
All right! All right! No need for all the drama.
One of those four is the killer, I'm sure of it.
The question is, which one? SIGHS And how they did it.
How did one of them stab Will Arnott in the forest when all four of them were at base camp at the time of the murder? How was Ile Saint Felix? Uh, the body's on its way to the morgue and the first suspects are back on Saint Marie, sir.
Well, keep me abreast of any developments.
Will do, sir.
And enjoy taking your new boat out for a spin.
And, um, what led you to that conclusion, Inspector? Well, sir, first of all, you lookjaunty.
Jaunty? Secondly, those keys you're clutching, they're brand-new.
There's no house or car nearby, and they have a float on them.
And thirdly, I saw you stealing a loving glance at .
Hortense over there.
Party tricks don't impress me, Inspector.
But good, solid policing always does.
He's definitely warming to me.
Bethan, love.
There's something you're not telling me.
Like what? Like what happened on that island.
Something happened, didn't it? Wh? Beth DOOR LOCKS SHOWER STARTS PANTS NERVOUSLY HUMS HAPPILY Wakey, wakey, sleepyhead! LAUGHS Wow.
You really know how to celebrate your wedding anniversary.
SIGHS We had an argument.
Oh, I'm sorry, do you want to talk about it? GRUNTS No.
Oh, this is a serious one.
I just think that you should try to worry less about it all.
I've learned that a Saint Marie way is to relax a little more, to embrace the environment rather than fight it.
Oh, the principle of paranoid behaviourism.
Yeah, you're saying that if I expect to be bitten on every square inch of my body, then that's exactly what'll happen.
Something like that.
Oh, well, thank you for that diagnosis, DS Dumas, but I think I'll stick with the medication and regime already prescribed to me, you know, by actual doctors.
Morning, guys.
Oh, morning, sir.
Morning, Sarge.
How are we getting on? So, the pathologist confirmed that Will Arnott bled to death from a stomach wound.
Plus, the wound matches that of the spearhead we gave him for comparison.
How about his background? Eh, so, the victim is ex-SAS soldier William "Wolfie" Arnott, 44 years old, served in Iraq with the M Squadron.
He was discharged three years ago.
Employed at Trackers Adventure Travel, a company specialising in adventure holidays.
Now, I spoke to the company's HR manager.
They didn't give out details, but from what I gathered, Will suffered from PTSD.
Huh, poor guy.
Hm, and he was getting counselling, sir.
Do you want me to talk with the counsellor? Yes, please.
Did he have any family? No wife or children.
He lived alone in a flat in Brighton, England.
His parents divorced when he was 16, and he joined the Army at 17.
JP, Ruby, when we're done here, will you go and give his villa the once-over, see if that turns anything up? Absolutely.
OK, suspects? We've got David Hammond.
Not much to tell, really.
He's an IT consultant living in Surrey.
And he came to the island with his girlfriend, Bethan Miller.
She's 30 years old, a junior school teacher.
What about this guy? Malcolm Simmons.
He's 42 years old, divorced.
He works as a family law solicitor and he attended Thornmoor School in Worthing and then went to university.
Worthing's near Brighton.
Any chance Will Arnott went to the same school? I already checked, no William Arnotts.
Good work, both of you.
And what about this one, old Bubblegum Betty here? Casey Booth.
She's 22, from Liverpool, and she is a vlogger and influencer.
Yeah, she's got two previous convictions for assault, a fight in a nightclub and a road-rage incident.
So she has a temper.
Well, yes, she does, sir, but, you know, that's part of her appeal.
She says it as it is.
LAUGHS Her vlog is called The Scouse That Roared.
CHUCKLES That's quite good, actually.
I think that is why she had her phone on the island, sir.
To record her vlogs.
Anything of interest on them? Yeah.
A video she made the morning of the murder.
Hi, guys.
It's day five of Desert Island Casey, and things are getting tense out here.
Last night, it all kicked off big style.
WILL: Casey! Coming.
Sounds like Major Moody's on the prowl, so I'd better say ta-ra! LAUGHS Give me the phone now.
No way, it's mine.
Give it here.
Just back off, pal, or I'll show everyone what you've been getting up to here.
Is that what you want me to do? Just give me the bloody phone.
Oi! Just get off me! Look, I admit, Will and I, we had a bit of a barney, got a bit physical.
I don't deny it, but my phone, it's my livelihood.
So you came here to, what, give a review of the place? Not at first, no.
Just thought it'd be fun to film.
But? But as it went on, I felt I had to, you know, give my followers an honest account before any of them wasted their own money.
How do you mean? Well, just all sorts.
Will would get drunk, lose his rag when we couldn't do stuff he'd asked us.
You know, I know he's dead, but the guy had some serious issues.
What troubles me, Casey, is, how did you get the phone back after he took it from you? Well, he had no right to take it in the first place.
You were angry.
Damn right I was angry.
You have two previous convictions, right, both for assault? Look, OK, I had a bit of a short fuse, but that's ancient history.
I'm a different person now.
I lost it with him, but by the time I got back to camp, I'd cooled down, I swear.
How did you get the phone, Casey? When Dave ran back after finding the body, I went to have a look.
And, yeah, got my phone back.
Look, I'm not proud of it, but I didn't murder him to get it.
And more to the point, how could I have? Cos I was with all the others when it happened.
SHE SCOFFS Well, something must've happened.
Look, I don't want to talk about it.
JP, a problem shared is a problem halved.
Come on, JP, just tell me what you and Rosey argued about.
All right.
But if I tell you, it goes no further, OK? Cross my heart, hope to die.
Rosey told me she was pregnant.
Oh! Congratulations! Oh, that's so amazing! Best news ever! Well, how did it end up with you being kicked out of your house? Man, she was so excited.
It was like she was waiting for me to say something.
And? I hesitated.
You hesitated? But it was, like, only for one second.
JP, you should've been down on your knees, praising her for the goddess that she is.
Yes Not stopping to think about if you are happy or not.
Do you not know anything? You know what I don't understand? What? Will Arnott was stabbed here, in the lower central abdomen, right? Mmhm.
No vital organs were hit, he just bled out.
Well, don't they teach you all that stuff in the Army? I've just been on a survival website there, and they've got a whole section devoted to treating wounds using moss to stop the bleeding, what plants to use as antiseptic, improvised field dressings Well, maybe he was drunk, passed out.
Yeah METAL CLANKS Hold on, is that empty? Will came back to camp, filled up his water canteen and then set off to check the traps.
PHONE RINGS Hello? We were looking through the victim's e-mails and found this.
When head office sent Will Arnott the list of attendees for this week, what was weird was, when the list came through, he immediately started running a search on Bethan Miller.
It's all here in the history.
Why was he so obsessed with her? Her name obviously meant something to him.
Can we look at this one? "Reigate Resident Leads Tributes To Soldier Brother.
" So her brother was in the Army.
Along with Will.
That's great, thank you.
According to the local register office, the death certificate shows that Liam Miller, Bethan's brother, died at his barracks in Oxfordshire three years ago.
It was recorded as death by misadventure.
Sir, I just spoke to the UK Army Welfare Service.
They were very reluctant to talk to me when I mentioned Will Arnott.
You managed to loosen their lips, though, didn't you, JP? I managed to loosen their lips, sir.
They eventually confirmed that Liam Miller was an officer cadet in M Squadron, under the command of Major Will Arnott.
Death by misadventure.
It makes my brother sounds stupid, his death was his own fault.
You don't think it was? It was all covered up.
But Will Arnott, he targeted my brother.
He thought he was a weak link, so he decided to make an example of him.
What did he do? He ordered two soldiers into his room at night.
They restrained him and beat him with soap bars.
Then just left him.
They hit him so hard that his lung collapsed.
He died there, in the barracks, alone.
I'm sorry.
But Will Arnott was the officer in charge.
That makes him responsible.
So that's why you came here, for revenge.
When I first found out what he was doing now, I just needed to come and ask him what happened, to his face.
And? I watched him for the first couple of days, just trying to work out what kind of man he was.
He was a bit Jekyll and Hyde, depending if he'd been on the booze or not.
But you did eventually confront him? Yeah.
GRUNTS My brother's dead because of you! Liam Miller, do you remember? He wasn't meant to die! SHE SOBS He was pathetic, snivelling like a little child.
Does your boyfriend know why you're here? But I asked him to stay out of it.
Look, I didn't kill him.
In that moment, I wanted to .
but it wasn't going to bring Liam back, was it? Are we done? For now.
She's really convincing.
What do you think of the boyfriend, Dave? A bit of an eager beaver, isn't he? Well, he's nervous, for sure.
Well, love can make you do crazy things.
PARKER GROANS Oh, it's bugging me, it's really bugging me! OK, look, I think I might be able to find a longer ruler somewhere, sir.
No, no, no, not the bites.
It's bugging me how all four suspects can confirm they were together in the camp at the same time as the murder was taking place half a mile away.
Any ideas? Well, I've been looking through the financial records of the victim, and he definitely was strapped for cash, but I can't find any actual debt.
And I've been trying to dig a little deeper into the victim's life prior to him joining the Army.
SIGHS Sir, it's like the man never existed before that.
There's literally no records of a Will Arnott.
Wait, didn't you say his parents got divorced? Yes, at 16.
You don't think he could have just changed his name? That's a point, sir.
I'll check it out.
Well, actually, it's late now, which means it's even later in the UK, so you'll have to wait till the morning, which is probably as good a time as any to call it a night.
So go get some rest.
Thank you.
Night, sir.
Do you need a lift? Oh, no, thank you.
I'm going to go home via the market, pick up a few candles, the lemony ones that mosquitoes hate.
I know you probably think I'm overthinking it again No, I'm not.
I hope it helps.
Night, then.
Anti-mosquito? Yes, of course.
Oh, um, I'll take six.
Just to be sure.
Six? Oh, OK.
Sir Sir? CAR HORN BEEPS Sir, sir! Thank God you're here.
I need to ask a favour.
I'm afraid I'm on my way to the annual yacht club dinner.
I appreciate that, sir, and I'm really sorry, but one of the suspects from our murder inquiry is on the move, and the thing is, sir, I need to, um .
I need to commandeer Hortense.
This is really important.
I think he might be trying to flee Saint Marie.
I really do appreciate this, sir.
Hopefully, we'll have you back in time for your little shindig at the boating club.
It's not a shindig, it's dinner, and it's the yacht club.
Right, sir.
Well, technically speaking, this isn't a yacht.
Perhaps you should call for backup, Inspector, because it looks to me like your suspect is returning to the scene of the crime.
Oh, Mosquito Island.
At sunset.
JP, I need you and Ruby to head to Mosquito Island ASAP.
In your own time, Inspector.
Sir, it's the forest of 1,000 bites.
If I walk in there, it's like ringing the dinner bell! How are we going to find him? He must have come back because he left something behind.
But where? Now, Dave was always a bit of an eager beaver.
He found the body, he made the call and he was the first person to meet us when we got to the island, alone.
Would you be walking around alone if you thought a killer was on the loose? No.
He chose to be alone on the trail between the camp and the clearing where we first landed.
Why? TWIG SNAPS Cleaning up your mess, Dave? Think very carefully about what you do next.
If I were you, I'd start by telling us EXACTLY what happened to Will Arnott! I've got nothing to say.
THUNDER RUMBLES JP and Ruby should be here by now.
THUNDER RUMBLES Sir, we have a problem.
JP says the harbour master has declared a storm warning.
No boats are allowed at sea.
So we're stuck here, are we? No, no, we can't be.
I'll call JP and get him to send a helicopter.
Oh, it's ringing.
Inspector JP? JP! Inspector! JP! Hold on, I've been cut off, I've been cut off.
JP! Inspector, Inspector What?! We need to go back to the campnow.
You'd understand, sir, I can't stay here.
I have a routine, medications that I need.
If that routine goes out of whack, then so do I.
I'm not asking you, Inspector.
You know, we'll see the storm out here, at least until we hear from the Inspector.
Don't you want to call Rosey, let her know you'll be back late? I sent her a message.
You mean you don't want to speak to her just in case she hasn't calmed down yet.
Shall we have a drink while we wait? Yeah, sure.
SIGHS So When Rosey gave you the good news and you, um .
Mm, that.
Were you not happy to find out that you were going to be a father? Of course I'm happy, Ruby.
I was just It just came out of the blue, and, I don't know, in that moment .
I was just scared.
Scared of what? Look, I'm not even a sergeant yet.
How am I able to give the child everything it needs? I mean, what do children need, JP? Designer shoes, a boat, diamond rings? Children need love, that's all.
Being a father is a big deal, man.
Listen You've looked out for me since day one.
You've been patient, you've put up with my mistakes.
Now, I know there haven't been many, but even so.
You've made me a better police officer, better than I could have ever imagined.
So if ickle JP Junior .
gets half as much kindness and support as you've given me, then he or she will be fine.
So call your wife and make it up.
You're a good friend, Ruby Patterson.
Yes, this I know.
And don't tell her that you're working late with your hot co-worker.
THUNDER CRASHES This rain is really going to bring the mozzies out when it stops.
Water activates the dry eggs that the female mosquitoes lay.
My mum always says, "Take a cagoule with you, whatever the weather.
" She sounds like a wise woman.
SIGHS Lemon bonbon, sir? Sorry about my little outburst earlier.
I've just been rather discombobulated since I arrived in Saint Marie.
You strike me as someone who is rather discombobulated a lot of the time.
I don't choose to be like this, sir.
And however it may appear, I do try my best to just get on with it, manage it.
That's all I want, really, just for my life to function as normally as possible.
I'm not good at much in life .
but solving puzzles, murders, now that I can do.
THUNDER CRACKS I don't doubt that, Inspector.
I just think your various idiosyncrasies may mean you're not suited to being a good detective out here, in the Caribbean.
Goodnight, sir.
Goodnight, Inspector.
THUNDER RUMBLES GROANS EXHALES SHARPLY I found these coconuts down by the beach.
Thank you.
Inspector You've been ravaged! Well, to be honest, it's not as bad as I thought it was going to be.
Really? If I can get some cream on it by lunchtime, I should be able to get it under control.
You all right? Dave? I didn't kill Will Arnott, Inspector.
When Bethan came back from fishing with Will, she was off.
She was really agitated.
I could tell they'd had a bit of a row.
She was still angry.
And a few hours later, you found Will dead? Yeah.
So, like any good boyfriend, you covered her tracks for her.
Well, I tried to.
But she had no idea what I was doing.
I went back to the place where they'd been fishing and I found the broken spear washed up on the beach.
And, yeah, yeah, I buried it.
But then I panicked.
I thought what if your lot had come back and found it, what if it had fingerprints on it? So I decided to come back and get rid of it properly.
I think it's time we went home.
COMMISSIONER GASPS She's She's My boat! She's gone! I told you to tie her up! I did, sir! I did, but the storm.
I'll call JP and I'll get him to send another boat over.
And we'll call the coastguard.
I'm sure we'll find Hortense.
Argh! Oh.
Look, my cagoule.
Nearly forgot it.
Huh, what would my mum say? Well, that's a thought, though, isn't it? RECORDER BEEPS Initial examination shows the weapon used punctured the lower central abdomen, so I can only assume he must have bled out.
No vital organs were hit, he just bled out.
Don't they teach you all that stuff in the Army? I'm heading up to check the traps.
I'll be back before lunch.
Hold on, is that empty? I mean, that would turn everything we know on its head! Um, you've solved it, Inspector? In the process of, sir.
I'll chase our boat back.
Oh, Inspector, you're back.
Yes, I am! Morning, all.
Your face, what happened? Mosquito Island, Madeleine, that's what happened.
You should see the rest of my body.
It's like join-the-dots under these clothes.
Anyone have a torch I could borrow? Uh, yep, I do.
Here we go.
Thank you.
Ha, ha, ha, ha! Yes! Madeleine, do we have the case notes from the victim's counsellor? We do.
Now, if this all played out like I think it did, it's all a question of geography.
I found these coconuts down by the beach.
I found the broken spear washed up on the beach.
So, me and Case were down by the river, getting water.
I was out getting coconuts.
I was with Wolfie.
The question is why.
Why, Ruby, why?! JP, how did you get on looking into Will's parents' divorce? Oh, yes, sir.
I just came off the phone to his local records office, and you were right.
Up until the age of 16, Will's surname was Wainwright, not Arnott.
Now, I haven't checked it out, sir, but this is his medical and educational records.
Yes! Ha-ha! Here are the notes of the counsellor.
Thank you, Madeleine.
CHUCKLES So, you know what happened? I do now, yeah.
Do you want us to gather everyone, sir? I can't speak to everyone looking like this! Well, don't worry, sir, I used to be a beautician and I can work wonders with a concealer.
Thanks, Ruby.
Oh, JP, I need one more thing.
What's that, sir? Chopsticks.
Chopsticks? Hello.
There's a line in Robinson Crusoe, "Redemption from sin is greater than redemption from affliction.
" Redemption from sin is exactly what Will Arnott was looking for.
He was a castaway, too.
A loner, washed up on that island, hiding from a past filled with violence and anger.
But no matter what he tried, the old demons would resurface.
He'd drink, he'd lose his temper, he'd lash out.
He couldn't escape his very worst self, which must have brought back awful memories for you, Malcolm.
You were sick of people pushing you around.
You came out here to toughen up.
But instead, you became a murderer.
CHUCKLES NERVOUSLY Because you killed Will Arnott, didn't you? Or should I say you killed Billy Wainwright, your old school bully? What do you mean? I'm sorry, Malcolm, but itit's all in here.
Thornmoor School.
You were the year below him.
We missed it at first because Will changed his surname when his father left, took on his mother's maiden name, Arnott.
But he used to be Billy Wainwright, didn't he? I can only imagine Malcolm's shock to discover that the very man whose ghost he was trying to exorcise was the same one running the survival course he'd just come on.
And yet, I'm willing to bet that, when you arrived, he didn't even recognise you.
You must be my new group.
This is Dave.
Hi, Dave.
Casey, hello.
Er, Malcolm.
Malcolm? Welcome, everyone.
Welcome to paradise.
And then, when Will started drinking, after being reminded of his brutal past by the appearance of Bethan, whose brother was killed at the hands of bullies under his command, well, then he did what all bullies do.
He took out all his rage and anger on the weakest member of the group.
You won't even stand up for yourself.
Suddenly, it was all happening again.
The same man who ruined your childhood was ruining this, victimising you yet again.
By your own admission, you never fully recovered from what Will did to you as a kid.
You told me yourself, you'd grown into someone who just put up with people treating you badly.
That's why I came out here, you know, to toughen up.
And yet, you still tried to quell those feelings you had towards Will, all that resentment, all that anger.
You even succeeded for a while, until that morning, when you went out to get provisions for the camp, and you saw Bethan confront Will about her brother.
Liam Miller, do you remember? I'm so sorry.
You made his life hell! Hearing again about another poor soul victimised by your old school bully, something just took over, an instinctive, primal desire for revenge.
Hey, Will.
You don't remember me, do you? Malcolm Simmons.
You ruined my life.
Wait, wait Oh! GASPS Well, it wasn't the most sophisticated murder, Malcolm, but we didn't catch you for a while because you had an accessory.
Will Arnott himself.
Because now we get to the point where even you don't fully know what happened next.
These are the case notes from Will Arnott's counsellor back in the UK.
And as we now all know, he was a very troubled man.
And the notes are very clear.
When sober, Will Arnott was filled with self-loathing.
In these sessions, he talks constantly about how his death would provide comfort to those whose lives he'd ruined by his actions.
So .
this is what I think happened.
After pulling out the spear, he could have cried out for help.
He could have used the skills he'd acquired over the years to treat the wound, maybe even survive.
Or he could have done what he really wanted to do.
He could have died.
But he knew that, in doing so, he'd be sending you to prison for the rest of your life, a life he'd already ruined.
So he staged it.
He staged an entirely different kind of murder to protect you and, in doing so, hoped to find some sort of redemption, his redemption from sin.
He packed the wound with moss, an old survival technique to prevent bleeding out.
And then he used the belt from his rucksack to put pressure on the packed wound and, crucially, to disguise it.
And then, well .
I can only imagine the surprise on your face, Malcolm, when he sauntered back into camp.
Guys, I'm heading out to check the traps.
I'll be back before lunch.
But it was the only way he could give you a cast-iron alibi for the murder.
Then he made his way to a different beach, and he left a series of footprints to give the impression that someone had come to the island by boat and then left the same way.
Then he headed to the clearing, where he cleaned the wound, meticulously removed all the moss using the water from his canteen.
In his dying moments, he knew he had to get rid of one last piece of evidence, the blood-soaked moss.
He couldn't just throw it on the floor, because he knew that we'd find it.
So he thought on the spot and he hid it in plain sight.
JP, the chopsticks, please.
Thank you.
Will packed the moss into his canteen, shoving it down to the bottom, where it would stay safely jammed in.
So .
having hidden that final piece of evidence safely from view .
Will Arnott laid down .
and died.
I hated him so much.
You didn't need to kill him.
Um, I thought his death would, um, bring me some peace.
But I was wrong.
Officer Hooper, Patterson, please.
JP! I hear congratulations are in order.
Thank you, sir.
I'm so excited.
Really? I'd be terrified.
Ignore Neville, JP.
Having children is the most wonderful thing.
I'd better get this.
Inspector, I'd like to congratulate you on a job well done.
Thank you, sir.
I couldn't have done it without your help.
No, you could not.
And I'm sure you'll be pleased to know that the coastguard found Hortense.
Great news! Off the coast of Montserrat.
If there's any damage to her, I'll expect full compensation.
Just send me an itemised breakdown of the receipts, and RUBY CLEARS THROA Just tell me what I owe you, sir.
What is wrong with you, JP? You look ill.
Are you OK? Twins.
ALL GIGGLE We're having twins.
Felicitations! Double the fun! Yes, JP.
I never thought you had it in you, boy! Well, if I may, a toast to JP and his wife, Rosey, and to neither of them ever sleeping again.
Twins! No sleep! Twins! Traditionally, the groom was supposed to remove this with his teeth.
Of all the days to commit murder, the killer chose to do it on the day the victim's niece was supposed to be getting married.
Ruby? Did Ruby say anything to you about her and Henri? Keep an eye on her.
Well, I guess I have no choice but to deal with the little green monster.
Deal? Here, Harry, Harry, Harry.
