This definitely came with the post, right?
I can see how this looks to you.
It doesn't mean I'd want Jake dead.
It wasn't Rose who killed Jake.
I still refuse to believe that she'd be capable
of something like this.
David Cartwright is loosely connected to the victim's wife.
I hope that doesn't mean I'm a suspect now, Inspector.
You killed an innocent man for no good reason.
How are you going to prove it?
DNA is not going to cut it in court.
He's going to get away with it.
Cartwright, we need to talk.
Neville Parker, I'm arresting you on suspicion of the murder
of David Cartwright.
It's not long now, ma'am, the hotel is just around the bay.
Thank you.
I'm at the hotel. The local force are meeting me here.
Yeah, actually, I think that's them, I have to go.
Detective Inspector Karen Flitcroft, Department of Policing Standards.
Welcome to Saint Marie.
This is Detective Sergeant Naomi Thomas.
It's good to meet you, Inspector.
Commissioner Selwyn Patterson.
Commissioner, just to say it, and with the greatest respect,
obviously, I have no problem with senior officers tagging along.
But let's be clear the situation we're in,
one of your officers has been arrested for murder.
Which means...
..this is my case.
I take it that won't be a problem, sir?
Of course not.
I'm here to help.
So, we...
First up, I'd like to see the hotel CCTV footage you recovered.
Then I'd like to attend the crime scene.
Sure.
He was troubled and anxious, your man.
Well, without the evidence to charge Mr Cartwright for murder,
we were all feeling frustrated.
I've read the case notes, I know why DI Parker looks so agitated.
He then enters Mr Cartwright's room and he leaves...
..20 minutes later, yes?
Yes, ma'am.
Yourself and a uniformed officer arrived 15 minutes
after that and found David Cartwright dead...
Knife wound to his stomach.
That's right.
And no-one else was seen entering the bungalow through that door
in the time between Inspector Parker leaving and the victim's body
being found dead?
Correct.
The victim's body was found there.
And these glass doors, they were locked when you arrived?
We secured the crime scene as soon as we found the body.
I checked those doors and they were locked.
And the key for them?
They were on that dressing table over there.
It was bagged and taken to the station.
The only other copy was locked in the safe behind reception.
So if these doors were locked and all the keys accounted for,
no-one came in this way.
Which means the only person who accessed this room was DI Parker...
..when the victim let him in?
Also correct.
It's looking pretty clear cut, he's ticking every box
for means, motive and...
..opportunity.
I get the feeling his colleagues think he might be innocent,
but from where I'm standing with the evidence
I've seen so far...
..my gut's saying he did it.
Morning, Inspector.
Morning, Darlene.
Morning.
How are you doing?
I'm OK, Darlene.
Here.
Thanks.
Marlon and I were just wondering...
Would you like us to let your mum and sister know
about what's going on?
Not just yet, if that's OK?
I hope you already know this.
We are all on your side.
We know you didn't do this.
We're all going to stand and fight for you.
Whatever it takes.
Sir, the Commissioner called...
They're on their way back.
Oh, snap.
I've got one of those.
Yeah, I'm a big fan of the old Dictaphone myself.
Commencing interview at 11:15 am.
DI Karen Flitcroft present with the suspect...
Oh, er, Detective Inspector Neville Parker.
DI Parker...
Perhaps we should start by you telling me how it is you ended
up going to David Cartwright's hotel room on the night in question?
Yes, well, um...
We were unable to bring charges against Professor Cartwright...
..even though I believed...
I knew he was guilty of Jake Dalton's murder.
You killed an innocent man for no good reason.
You won't get away with that.
Then when I got home...
I found that Professor Cartwright had left me
a signed copy of his book.
And that bothered you?
Yes.
He'd killed an innocent man, and now he was gloating about it.
It was a very good try, though, but...
..no cigar, as they say.
So you drove to the Manda Bay Hotel to confront him about it?
I did.
With what intention?
I don't know.
I was reeling, I wasn't thinking straight.
But it's fair to say you were angry?
Yes.
So you arrived at the hotel and you went and knocked on the door
of David Cartwright?
Come on, open up, I know you're in there.
Hey!
Yes.
What did you say?
I told him that we needed to talk...
That I had some things I wanted to say.
He could see I was worked up.
Inspector, are you all right? You don't seem yourself.
I've had enough of the games, Mr Cartwright.
I told him it was time to drop the act.
It was time to stop playing me.
That we both knew the truth.
Perhaps we should talk about this inside?
You were in there for 20 minutes.
What was said?
Bear in mind, we have a witness that said they heard raised voices
coming from that hotel room.
What kind of psycho just kills someone to show how clever they are?
I put it to him again that I knew he was guilty of Jake Dalton's
murder, that I knew how he'd done it.
He continued to deny it.
What was your response to that?
I just wanted him to explain it to me.
What was he hoping to achieve?
Why was he playing such a...
..weird, sinister game?
And did he?
No, he just continued to insist that I'd got it all wrong,
that I wasn't thinking clearly about it.
He was enjoying it, like he was relishing every moment.
That must have been frustrating.
Yes, it was.
But that doesn't mean I lost all sense and stabbed him.
I didn't do this.
DI Parker, if you didn't kill the victim,
why does all the evidence make it look
very much like you did?
I don't know.
I can see how this all seems to you, but I did not do it.
Can you think of someone else who might want to do that?
No, not yet, no.
But there are some occurrences recently in my life
that might be connected.
Occurrences?
Well, my home was broken into recently, just over a week ago.
What on earth?
It was messed up, but... Oh, my God!
..nothing was taken.
We still don't know who did it, or why.
I'll need to see the crime report.
DI Parker, I've been to the crime scene.
The back doors of that hotel room were clearly locked, and the only
person seen entering through the front door was you.
So if you didn't stab the victim, how did someone else do it?
I don't know.
This is a crime report we filed on the break-in
at the inspector's home.
We dusted for prints, but we found no matches on our database.
No witnesses either.
OK.
Do you have a map of the island lying about this place?
Yeah, I'll dig one out for you.
Is it OK to work at this desk?
Erm...
For now, you can use it.
Inspector?
I wonder, could we talk in private for a moment?
Sir.
I know what you're going to say, sir.
You don't think he did it, do you?
It's understandable.
Colleagues work closely with an officer,
they become blind to his failings.
Find it difficult to think ill of him.
Actually, I often do find myself thinking ill of DI Parker.
Since his arrival on Saint Marie, he has proven himself
a consistently frustrating and annoying person.
Oh, right.
But despite all that, I can also say...
..he's both a good detective and a good man.
I don't doubt you've seen your fair share of corrupt police officers,
but in this instance, DI Parker is not one of them.
Sir, if you really believe DI Parker's been framed,
you need to work out how someone else did this,
because the physical evidence is beyond damning.
You need to find yourselves a suspect.
We have just 48 hours until DI Parker will be charged with murder.
So we must use every second available to prove his innocence.
But, sir, who would do something like this?
Kill a man and then frame an innocent police detective?
The obvious place to start is going through past cases
the inspector has investigated.
Someone who holds a grudge?
Mm-hm. Marlon, you and Darlene could start working through
every case file from the inspector's time on the island.
Yeah, let's go.
I also don't think we should discount the two suspects
from the inspector's most recent case.
Were either of these two aware that David Cartwright
was a suspect in Jake Dalton's murder?
We never told any of them that.
As Jake Dalton's widow, it does give Rose a possible revenge motive.
But why also frame the inspector?
She had no grievance with him.
Let's check their alibis for the time of the murder.
It's close to 24 hours since renowned criminologist and author
David Cartwright was found murdered in his Manda Bay Hotel room.
The police are yet to release any further statement.
So now the guy you work for has been murdered.
What is going on with this?
As far as we are aware, at this stage,
no arrests have been made.
Commissioner, DS Thomas, I'd like to organise a police dive team.
The road from the hotel where David Cartwright was murdered,
back to here, it's coastal all the way.
DI Parker could have thrown the knife into the sea...
If he did it, you mean?
The dive team? Can you sort that?
DS Thomas can liaise with the Guadeloupe police force for you.
You are the only people outside the investigation who know
that DI Parker is officially a suspect.
That remains the case until I say otherwise.
If the press do approach you, say nothing and send them my way.
OK. How is Neville?
He's coping admirably, considering the circumstances.
You're going to resolve this, Selwyn?
You're going to get Neville off.
We all know he didn't kill anyone.
We're giving this everything we've got, I promise you.
Actually, are you allowed to give him these?
It's his eczema cream and some antihistamines.
I'm worried being in that cell is going to cause a flare-up.
I'll make sure he gets them.
Thanks.
It's the commissioner, right?
It's Mrs Dalton?
And you are?
I'm Henry Baptiste, Rose's partner.
We're together now.
And how can I help you?
We saw the news about David Cartwright.
We went to the station to speak with Inspector Parker,
but they said he wasn't available.
Look, I don't know what is going on here,
but we need you to know it wasn't us.
You can't drag us into all this as well.
The investigation into Mr Cartwright's murder is ongoing
and remains confidential.
I can say no more than that.
Let's just go, Henry, please.
There's something going on, something off about it all.
And where's DI Parker gone?
Still no progress, sir.
We are struggling to find ourselves a possible suspect.
Most of the people who might have some sort of grievance
are safely behind bars.
So what can we do next?
As well as looking to the past, I want us to keep our focus
on the present, on the crime scene specifically.
The key to finding our killer might well lie there.
Who are the current witnesses from the hotel?
The staff on shift at the time of the murder,
and the residents living close to the victim's bungalow.
Then go back, speak to every single person at the hotel
on the night of the murder.
We'll get right to it, sir.
Commissioner, Inspector, I've got something you should see.
The fingerprints we lifted from the break-in at your home, sir...
I expanded the search field to include the exclusion prints
from all the cases we've investigated
over the last six months.
And you got a match?
Whose fingerprints are they?
Justin West.
From the preppers' commune?
Mr West was very shaken up by the arrest of his wife, Raya West.
Raya, what's happening to her?
She's been charged with manslaughter.
Yeah, he didn't take it well at all.
So might this be the man who trashed your home?
Mr West, are you home?
Commissioner, in here.
Remember me, Mr West?
Detective Sergeant Thomas.
Is it Raya? Has something happened?
No, that's not why we're here.
I'll get you a glass of water.
Mr West, perhaps you can start by explaining why you broke
into DI Parker's home?
I didn't, I don't know what you're talking about.
Your fingerprints were found on a number of items.
So we know for a fact that you were there.
Look, I didn't mean him any harm, OK?
I just...
I just needed some cash, that's all.
All our savings went on legal fees.
No-one wants to know me after what Raya did.
What happened, exactly?
I don't know, I just started...
..following him, your inspector.
Not every day, just...
..when I'd been drinking, when I felt angry.
So you admit you went to his home?
I was just going to take some cash as a sort of...
..recompense.
Once I got inside, I just kind of...
..lost it.
Well, why him?
Because if he'd just left us all alone instead of sticking
his nose in, I'd still have a wife sat here beside me,
instead of this.
And then two days ago, once again...
..your anger got the better of you.
I don't know what you're talking about.
Inspector Parker has been arrested on suspicion of murder.
A murder we believe he didn't commit.
Because someone framed him for it.
Someone very angry.
Very bitter.
No.
Look, I was angry, I admit it, and I shouldn't have done
what I did to his home, but I haven't killed anyone.
That's ridiculous.
Afternoon, Inspector.
Dive team found this quarter mile from the hotel
where the victim was stabbed.
Matches the size of the wound exactly.
I want to see if it's from a set.
So this is where you put them up, is it,
your English detectives?
Huh!
Um, excuse me.
Er... You can go in.
Hello?
Officer Pryce?
What news?
Professor Cartwright had left me a signed copy of his book.
Inspector?
None of the knives match the one you found.
It's a pretty random selection.
OK, I want the knife tested for blood traces and dusted for prints.
And Sergeant, bag that as well.
That was Marlon.
He's had no success finding a witness at the hotel.
No-one saw anyone being suspicious the day of the murder?
There are an awful lot of lotions and potions in the bathroom.
Your DI Parker, a bit of a hypochondriac, is he?
Yes. Yes.
If you could drop me off at the hotel, I'm going to order room
service and hit the sack.
We'll see what the lab results bring us in the morning.
We're going to keep at it.
You know the saying, if it walks like a duck
and quacks like a duck...?
DI Parker is not a murderer.
But you are no closer to working out how someone framed him.
As I say...
We'll keep at it.
Sir, if someone intended to frame DI Parker, then maybe it was them
that sent him this book rather than David Cartwright?
But the book was signed by Mr Cartwright.
It also hasn't been released yet, so they'd have had to visit him
at his home to get it.
We could check with his neighbours, see if they saw any visitors
in the last day or so.
It's worth a try.
Bonsoir. Bonsoir.
We knew you'd be working late, so I brought you some snacks
and soft drinks to keep you going.
It's not a situation that can't be remedied by a cheese
and ham sandwich, eh.
Is there any news?
No.
We brought one for Neville as well.
Is that all right?
Of course.
I'll bring it through to him.
Is there any chance I could see him?
Or, is that against the rules?
That's not really allowed, I'm afraid.
Please, Selwyn, just give them two minutes.
Two minutes, no more.
I'll give you some time alone.
Thanks.
So, do I get a hug?
I know it's not been very long, but I have missed you.
I missed you too.
Sorry, think you just squashed your sandwich.
Ah, it was worth it.
Hey, your skin's flaring up, look.
I know probably anxiety or stress or...
Or both.
You know, when I was a kid, I was allergic to everything.
I was permanently red and itchy.
I hated the fact that I couldn't control it, that it controlled me.
Then I became a detective and I was good at it.
Finally felt like I was the one in control.
I don't want that to be taken away from me, Soph.
Hey, listen to me.
That is not going to happen, OK?
They're going to sort this out.
They're going to work out who's done this to you,
and they're going to get you out of here.
I know they will.
Come here.
There's definitely something going on, Rose.
I'm telling you, they think DI Parker murdered David Cartwright.
Why else would they be taking things from his home like that?
But why would he do that?
I don't know, but this could help us, you know, really help us.
There's newspapers would pay good money for a story like this.
And after the last few days, I'd say we're owed a bit of good fortune.
No, no, Henry, let's just leave it alone.
Stay out of it.
Lab results on the knife confirmed small traces of blood matching
David Cartwright's DNA lodged in the seam of the handle.
And two separate fingerprints found on the handle itself.
Don't tell me they are DI Parker's prints.
But somebody must have taken them from the shack.
I mean, we know it was broken into.
The place is hardly Fort Knox at the best of times.
How are we getting on with the alibis?
I had to confirm that Justin West was at the bar at the time
of the murder, and Rose Dalton and Henry Baptiste were seen together
at a restaurant here in Honore.
Also, sir, I've tried speaking to David Cartwright's neighbours,
but they must be away.
I've left a note for them to call.
Commissioner, I just had a call from my boss and there's
been a serious development and I can't quite believe I'm saying
this, but it could just be the lifeline you looking for.
DI Parker, DPS officers have recently been trying
to get in contact with you as a possible witness.
With me?
I haven't heard anything.
An ex-colleague of yours is under investigation.
A detective constable Andrew Buckley.
Andy? Why?
A case you worked on with him in Manchester in 2018,
evidence has recently come to light of corruption taking place.
No! That can't be right.
Andy's not like that, he's a straight up copper.
We spoke with him recently, he helped us out on another case.
I'm DC Andrew Buckley, by the way.
DS Naomi Thomas, it's good to meet you too.
So what can I do for you, Gov?
And he didn't mention that he was under investigation?
Not when we spoke with him.
He seemed fine, right, sir?
Yeah, except...
..he called me again a couple of nights later.
But, erm...
So now.. He sounded troubled.
What is it?
He said he needed to talk about something.
Sorry, I can't, Nev.
Then he just hung up.
That's what it was.
My colleagues are emailing over the case file, but the thing is,
their intel shows that Andrew Buckley fled the UK
a few weeks ago.
He came here, he came to Saint Marie.
Andy's on the island?
What the hell's he doing here?
It's been a long day, I know we're feeling tired,
but this is for the inspector.
We're bringing this guy in for him.
Understood. Yes, Sarge.
Now let's go.
OK, Marlon, you go around the back in case he tries to make
a run for it.
Let's go this way.
Sarge, suspect had already out the back and getting into a car, over.
Received, stand by, we're on our way.
I'll get the bike, Sarge.
Police!
Get out of the car, Mr Buckley.
Marlon, he's coming your way.
Marlon, do you copy?
Argh!
Hey, man, how's it going?
How did you get in here?
Creepy, right?
So why don't we get out of this car and I can slap these
cuffs on you, hey?
Sarge, the suspect has been successfully apprehended.
Come on, let's go.
Yeah, I remember this case pretty well.
Myself and DC Buckley worked it together.
It seemed pretty cut and dry.
This guy, Darren Biggs, was a known drug dealer back in Manchester.
He was found dead in a disused warehouse in Burnage.
He'd been stabbed.
We found out who did it very quickly.
It was a young woman who was couriering drugs for him.
Yeah, Grace Walmsley.
She claimed it was self-defence.
She'd turned up empty-handed after a rival dealer stole the drugs
she was supposed to be delivering.
Biggs got violent, she stabbed him.
Judge still looked at it pretty harshly.
She ended up with a 25-year sentence.
Why is this case being reviewed now?
The DPS got a tip-off that your colleague,
DC Buckley, was receiving payment from Biggs in exchange
for inside information about what the police were up to.
Now, when Darren Biggs was found murdered, it's believed DC Buckley
removed a significant piece of evidence from the crime scene,
a burner phone with his own name and number on it, obviously,
to avoid his corruption being discovered.
I can't believe this is who he is.
Nev.
I'm so sorry.
Andy, what did you do?
Detective Inspector Parker.
I'll accompany you back to the cells.
Sergeant, process DC Buckley.
The day after the DPS informed me I was being investigated,
Nev... DI Parker got in touch.
He told me about the case you were investigating.
DI Neville Parker, as I live and breathe.
Hello, mate, been a long time.
Too long, Nev.
But just seeing him again brought it all home to me.
I knew that the DPS were going to want to interview him
on the Darren Biggs case, he was the SIO on it.
And that bothered you?
Yeah, Neville's me mate.
So you were worried about his reaction when he found out?
I'd let them down and I knew he'd be hurt by what I'd done.
But why did you do it?
Take money from a drug dealer.
I just found myself in a little bit of debt,
my missus had moved out and I was left with a mortgage
I couldn't afford. Everything just started piling up.
I'm not proud of what I've done.
That's why I came here.
I wanted to tell Neville myself.
I wanted to say sorry to his face.
But since you've been here, you haven't spoken
to DI Parker, have you?
I tried a couple of times.
I just couldn't face it...
..his reaction.
So what? You just stayed here?
Well, yeah, being away from home, away from the DPS investigation,
it felt like it wasn't really happening.
But you knew DI Parker would find out sooner rather than later.
The DPS would have to contact him.
I know, and I thought, if I can do something where I can just delay
it a little bit longer and it somehow works itself out...
So what did you do?
I took his phone.
The inspector thought he lost it.
I can't find my phone anywhere, I must have lost it.
And then found it in his rucksack.
I'm sure I checked in here.
I put it back after I'd cloned it.
You cloned DI Parker's phone?
That's why my colleagues weren't getting any response from him.
You were intercepting his emails, his voicemails.
I was just trying to stop what was happening.
I know it was stupid because I knew it was all going to catch up on me,
but I was running from something and I couldn't stop.
I admit to all this.
And I'm deeply ashamed of every single part of it.
But this murder you're talking about, it wasn't me.
Why would I kill someone I've never even met and then try and frame
me mate for it? Why would I do that?
Maybe because you were trying to discredit DI Parker as a witness
in your own investigation. No.
Maybe you thought with your old boss languishing in prison for murder,
you could make it look like he was the corrupt officer back in 2018?
I'm not a killer.
I would never, ever do that to Neville, ever.
Where were you between five and six o'clock two nights ago?
Erm...
The supermarket up on Port Royal.
Think I stocked up for the week, so I should be on their CCTV.
Sir, we just finished searching Andrew Buckley's apartment...
Nothing there.
We've got the phone he used to access the inspector's emails.
Sergeant.
Commissioner.
I've just watched the CCTV footage from the supermarket in Port Royal.
It confirms Buckley's story.
So as it stands, the only person who could feasibly have murdered
David Cartwright... Is DI Parker.
We are officially out of time, sir.
I have enough evidence to charge him.
So unless you've suddenly worked out how someone else managed
to magic their way into Cartwright's hotel room and murder him?
Sir, did we get this wrong the entire time?
No.
No, we did not.
Detective Inspector Neville Parker.
I am formally charging you with the murder of David Cartwright.
Do you understand what that means?
I'm sorry, sir.
It's OK, Marlon.
It's OK.
Neville.
Mrs Parker, this is Commissioner Selwyn Patterson
from the Saint Marie Police.
Your son, Neville...
..has asked me to call you.
Commissioner, I'm heading back to the hotel.
I'll finish my report there.
I will email you a copy when it's done.
You go on and write up your report, convince yourself
you've done a good job.
But I believe policing is about doing more than the bare minimum.
That is not fair, sir.
You sort of do nothing more than prove a man's guilt.
Uninterested in the possibility of his innocence.
But I don't doubt that very soon your DCI will call
you into their office to tell you you've got the DI Parker
case seriously wrong.
I suggest you spend some time preparing your excuses.
I'll get that.
Saint Marie Police, officer Pryce speaking.
Good evening, sir.
Ah, yes, thank you for calling back.
OK, thank you.
Commissioner, sarge.
That was David Cartwright's neighbour on the phone.
OK.
The afternoon of the murder, she was passing by his house
and she saw a woman leaving, she got him to write something
into a book, and then she went.
Any more of a description?
Fair-headed, in her late 20s.
There's only one person on our board who fits that description.
Rose Dalton. But sir...
She has a verified alibi for the time of the murder.
Thank you.
Are you going somewhere, Mrs Dalton?
Home, to England.
I just want to go home.
Me and Henry, we're not...
I can't be with anyone right now.
I know things were rough between me and Jake, but he was my husband
and I loved him.
Everything that's happened since, it's just...
It's too much.
It's all been too much.
The afternoon before David Cartwright was murdered,
we understand a fair haired woman around your age
was seen leaving his house.
Was it you?
No.
I didn't go back to Mr Cartwright's at all after Jake was found dead.
I'm sorry, I don't know who this woman is,
but I promise you, it wasn't me.
How are you doing?
It will get sorted, all this.
Neville will be free again soon.
I just know it.
I'm going to head home.
Will you be all right alone?
Of course.
Night, Catherine.
It was the wrong key.
Why does it matter that it was the wrong key?
We go over everything again.
We need to know who that young woman was who sent that book to DI Parker.
If it was the wrong key, then it can't have opened the door.
Which means the killer had to have the right key.
But when was it put back? That's the question.
When?
Neville Parker...
I'm arresting you on suspicion of the murder of David Cartwright.
It has to be at the police station.
No, no, no, no, no, no.
It can't be.
Could that be it? Sir?
Grace Wilmslow took her own life a year into her prison sentence.
Grace Wilmslow killed herself.
DI Parker arrested Grace and charged her with murder.
Is it possible someone might hold DI Parker responsible for her death?
A close friend, a family member?
We've been working through DI Parker's past cases on the island.
But what if it's a past case from his time in Manchester?
Grace Wilmslow grew up in a care home with her older
sister, Rebecca Wilmslow.
She was her only relative.
A sister.
Hello.
I need to talk to somebody now, please.
I know who the killer is, you have to let me out.
Please.
Commissioner.
You already know.
I am so very sorry, Inspector.
I need some time, Catherine.
I just, I just need some time, Catherine.
Just need some time, Catherine, to get my head around all of this.
So I'm going back home to Manchester.
Go away, you stupid lizard.
You moving out.
Neville?
What are you... What are doing out...?
Oh, I've been released.
There's evidence come through that proves
I didn't kill David Cartwright.
That's great, it's fantastic.
So good to see you.
I know it was you, Sophie.
Sorry.
I know it was you that stabbed David Cartwright and then tried
to frame me for his murder.
What are you talking about, that's...
That's crazy. All right, stop.
Just stop.
All right, all the pretending, all the lies,
Just stop, it's over.
I know that you are not Sophie Chambers.
This is Grace Walmslow, a young woman who I arrested and charged
with murder back in 2018.
A year later, when she was 19 years old,
she took her own life in prison.
This is a photo from Grace's social media account.
Here she is with a big sister, Becca Walmslow.
That's you, isn't it?
You've been playing a game with me ever since you arrived
on the island, it wasn't an accident that we bumped into each other
at the airport at Christmas.
You contrived the whole thing?
Oh, no, I'm sorry.
I assume you even swapped our suitcases when I wasn't looking.
Just so you'd have to come and swap them back.
Then you can start worming your way into my life.
Oh, can I help you?
Just one big ruse.
What, one big con, right from the start.
All waiting for an opportunity to destroy me.
So, when I was unable to arrest David Cartwright for a crime
I knew he'd committed, you saw an opportunity to stage a murder
I had clear motive for.
Because I was frustrated that I hadn't been able to get
justice for the poor man whose life he'd taken.
And then...
..this book with David Cartwright's dedication,
"to my number one fan."
You made out like it had been delivered here.
But it hadn't... had it.
You went and got the book yourself.
You were the fair-haired woman David Cartwright's neighbour saw.
I saw your Q&A online.
You couldn't spare me a couple of minutes, could you?
You got David to sign it.
How about, "to my number one fan?"
Knowing if I thought it had come from him, the effect
it would have on me.
So when I left that evening to confront him at his hotel,
you followed me.
Neville, stop, wait.
You waited around the back of his room,
watching, as we argued.
You all right, Inspector? You don't seem quite yourself.
I've had enough of the games, Mr Cartwright.
You bided your time until I'd gone.
Then you knocked on the glass doors.
Sophie.
What a nice surprise.
Come in.
Once inside, you murdered him.
Oh.
But you then have to seal the crime scene.
You had to make it seems impossible that anyone could have entered
through the back door.
So you took the hotel key off its fob...
..and you replaced it for a similar key.
It didn't have to be identical, just close enough.
So that it could pass at first glance.
This key, right?
You then left the room.
Closed the back doors and locked them.
When my officers arrived at the crime scene, they found
the doors closed and locked and the fake key
still inside the room.
They had no reason to assume that a key on the hotel fob
wouldn't be able to open the back doors.
Plus, their own DI was quickly being identified as the prime
suspect, so they had no choice but to lock down the crime
scene immediately anyway.
You just had to wait for a convenient moment to swap
the keys back.
You were at the police station that night I was arrested.
No, wait...
..it can't be right.
My colleagues were shocked, confused...
..distracted.
You just have to brazen it out.
Until the opportunity presented itself to switch the keys back.
When the detective from the DPS visited the crime scene and tried
the key in the back doors, it worked perfectly because with your fake key
back in your possession, nothing appeared to be awry.
Ten out of ten.
Impressive stuff.
You know...
It's just a shame...
..It's a shame you weren't as meticulous when it came to solving
the Darren Biggs murder case.
Your sister stabbed him.
Are you saying that's not what happened?
I know she claimed self-defence, I did all I could.
Yeah?
How about the fact there was a corrupt officer,
your mate working on it?
You didn't pick up on that, did you? Hmm?
You know about that?
I have a few connections in Manchester.
Word gets around.
Well, so what? Is that what this is all about?
That I didn't realise my colleague was corrupt.
Wouldn't have changed the end result anyway.
Yes, it would.
She stabbed Darren Biggs.
The burner phone.
The one that was taken from the crime scene.
The one that belonged to Darren Biggs.
It would have helped Grace. How?
Because it would have shown she wasn't even meant
to be there that night.
She'd never done a drugs pick-up in her life.
She'd have got a shorter sentence.
If the judge had just realised she was an innocent girl who got
caught up in something her sister should have protected her from.
I don't understand.
It was me.
It was me who was supposed to be there that night...
..couriering those drugs.
It's what I did, it was my life.
It's how I kept me and Grace fed and clothed and a roof
over our heads.
It was never meant to be her life.
And that one night...
I was ill in bed, and Grace...
..she said she'd go in my place, and I let her.
That burner phone, there were months...
..years' worth of texts showing it was me working with Biggs,
not Grace.
If that's the truth, then why didn't you just say something?
Why don't you just come forward?
You could have cleared her name.
Because I didn't have it in me.
Because I'm a coward, and I always have been.
I'm her big sister and I sat there and I said nothing.
I let her go through all that.
And you, if you'd have just done your job properly,
if you'd have done what you were supposed to,
I would be in prison now and Grace, she'd still be here
and she'd still be alive.
I hate you, Neville Parker.
I hate you.
Inspector?
All right.
Rebecca Walmslow, I'm arresting you on suspicion of the murder
of David Cartwright.
You don't have to say anything, but it may harm your defence
if you do not mention many questioned,
something which you need to rely on in court.
Anything you do say may be given in evidence.
I've updated my boss, and he's happy for your team to continue
without us from here.
They also told him that maybe I should take some time
away from work.
Have a rethink.
Thank you.
Sometimes it doesn't hurt to put ourselves first.
This job I do, seeing bad people day in, day out.
You stop noticing the good ones.
Good luck, DI Flitcroft.
How is he doing?
He's confused, hurt.
But most of all, he feels like he let everyone down.
How did the silly man work that one out?
But none of us saw this coming.
She had everybody fooled.
Because he says he didn't see what was right in front of him.
If he had, he could have stopped it all.
Sir?
Mind if we join you?
Sure.
I'm sorry for not...
You don't need to apologise, sir.
Not to anyone, especially not us.
You've done nothing wrong, Inspector.
You got to know that.
You must all think I'm just such a fool.
No, we don't.
Not in the slightest, sir.
At least no more than usual.
You know?
Thanks for that, Marlon.
Any time, sir.
Welcome to Babette's.
The best music and vibes on the island.
Is that the 30-year-old?
Bet it's pretty tasty, eh?
A murder took place right under my nose and I didn't notice anything.
It turns out Darlene is a big-time calypso fan.
She won't stop singing, sir.
What if my instincts let me down again on a case, on this case?
So the poison was definitely added after the rum was poured.
I have no idea how or when anyone could have done that.
I think maybe it's time to call it a day.
You want to leave Saint Marie?
