Oh, there we go, Paradise Island, guys.

Me and my wife Rose moved out here five years ago.

Best decision we ever made.

Beautiful restaurants down here.

Recommend this one for seafood.

You are going to love it here.

Hey.

Here we are, lovely.

Right, let's get you on to dry land.

That photo was taken of me and the missus the day we got the boat.

New job, new life.

Haven't looked back since.

Thanks for using Jake's Taxi Boat service today.

Yes, madam, thank you, sir.

Thank you so much. This is for you. OK.

Ah. Thanks. Paradise, eh?

OK, have a lovely day, thank you.

Ciao.

Morning.

All right? Yeah, no worries.

I'm going to grab some breakfast and I'll pick you up at 11.

All right.

Rose, l'm back.

Hey, love, there's some chopped mango and yoghurt in the fridge,

I'm going to go get dressed. Wow.

So, l don't even get a quick kiss?

That's your lot, or I'll be late for work.

Right, brekkie time.

I just think it's really bad behaviour.

And l, for one, blame the parents.

She was only five years old, sir, and she did say she was sorry.

Next time the commissioner asks me to give a talk at the local

primary school, l'm telling him no.

I mean, look at it.

One of my favourite ties that was!

Well...

... I guess you could sew it back together.

There should be a law against children that young having scissors.

Afternoon, Inspector.

Afternoon, Darlene, did we miss anything?

Honore has been as quiet as a mouse-

Here's your mail.

Thanks.

So what's the story with his tie?

Er, the less said, the better.

Darlene?

Sir? This definitely came with the post, right?

Yeah, with the rest of the mail, why?

"A murder will be committed today."

That can't be for real, though, do you think?

I don't know.

I suppose it could be some sort of prank?

Well that's some dark sense of humour.

But nobody's reported anything today, have they?

There's not been a peep all morning.

Yeah, but today is not over yet, is it?

Sir, we've got a male late 20s, early 30s.

Paramedics reckon a blunt force trauma to the rear of his head

was the cause of death.

Who discovered the body?

A tourist boat coming in from a reef spotted the victim's body about

half a mile from shore.

And they were able to give us the coordinates?

They did.

But nothing in his pockets to identify him?

Only his phone, but it has water damage.

We'll have to get the pathologist to confirm, but it doesn't look

like he was in the water too long.

OK, so a few of the fishermen recognise the deceased.

His name is Jake Dalton.

How come they know him?

He ran a water taxi service from his home in Anna Bay.

He has a boat?

Could have been an accident.

Could have slipped, hit his head, fallen overboard.

It's possible, but there was no boat in sight where the body was found.

Also, the victim has a wife.

Her name is Rose.

I managed to get hold of her number, so I'm going to make the call.

OK.

Poor woman.

Thank you, sir.

I know this must be hard for you, Mrs Dalton, but could you talk us

through your husband's movements this morning?

He had the same routine most days.

Left for work early.

Came back here for some breakfast at 9:00.

Rose, I'm back. Hey, love.

He was still here when I left for work at quarter past.

And you didn't come back after that?

Not until I got your call.

I was at a client's house all morning.

And what is it that you do?

I work for a cleaning company.

We service a few properties on the island.

And do you know what your husband did after you left this morning?

He mentioned he had a customer up in Park Royal at 11:00,

but I don't know if he took the job or not.

Something the matter?

Eh, oh, no, nothing.

I'm sorry, do you mind if l quickly use your bathroom?

It's through there. Thanks.

So sorry again for your loss.

Goodness, Inspector, what on earth are you doing?

Bleach, Darlene.

This floor has recently been cleaned with bleach.

I could smell it from the living room.

Really? All the way from back there?

I have always had very efficient offactory receptance.

If you say so, honey.

So the victim's boat is still moored here, down at the jetty,

round the back of the house.

Well, that puts paid to the idea that he banged his head

and fell overboard. So, what then?

You think the body was dumped out there?

Look, the thing is, Inspector, the neighbour said that he heard

the victim and his wife having a pretty big row this morning,

not long after 9:00am.

But he said it sounded pretty fierce, loud shouting.

Just trust me, OK?

And it wasn't the first time.

There's been quite a few like it over the last couple of months.

We need to do due diligence, Darlene.

Let's test this floor for traces of blood.

You know, Inspector, it suits you not wearing a tie.

Oh! It makes you look less uptight.

Oh, thanks...

...l think.

Ah.

Now, would you look at that?

We just found our crime scene.

Yeah, all right, I don't deny me and Jake

had an argument this morning, but...

...married couples argue.

It wasn't about anything serious.

It wasn't the first time, though, was it?

Oh, my neighbour, he can't keep his nose out.

It's nothing to do with him.

So what were you arguing about?

Just life stuff.

It's been hard lately.

Jake's business hasn't been making as much money as we'd hoped,

and I've been working extra hours.

We can't afford to go out, so all we see is each other day and night.

But none of this means that I would kill him.

Look, I told you, when I left the house this morning,

Jake was still alive.

And you've no idea who could have done this?

Killed your husband and dumped his body at sea?

No.

You sure about that, Mrs Dalton?

Yeah.

Absolutely sure.

OK, well, this house is now a crime scene, so I'm afraid you're

going to have to find somewhere else to stay for the night.

And as your husband's death is being treated as suspicious,

we're going to need you to stay on the island. Understood?

Yeah.

She's edgy, anxious.

I agree, there's something she's not telling us.

Hmm.

Darlene, we're going to need a thorough search of the house,

please, and can you check Jake's boat for any signs of blood?

OK. Why don't I stay and help her, sir?

I mean, the quicker we figure out what's gone on here, the better.

I'm going to talk to the commissioner.

The commissioner?

Well, this is the only murder I've investigated where I've been

sent a letter announcing it first.

We've sent the originals to the lab for testing.

There are three possible explanations as to why

that letter was sent to you.

The first, as a practical joke.

Poor taste, no doubt, but it is possible someone just wanted to

tease the local police force.

Hell of a coincidence that the day they send it,

a murder actually takes place, though?

The second explanation, whoever wrote it knew

of Jake Dalton's impending fate and wanted to avoid his death

by notifying the police.

But if that were the case, surely they would include more details,

a place, a time, even just a name, would have helped?

It's too vague for us to have done anything about it.

Which leaves us with one remaining option.

The killer sent it as some sort of taunt.

It was addressed to you specifically.

I did wonder if it might be connected

to what happened at the shack.

The break in, you mean?

Oh, my God.

What on earth?

Yeah, we still don't know who did it, or why.

Nothing was taken.

Could be linked?

Have there been any other occurrences since?

No.

But if they were trying to play some sort of game,

toy with me...

...how does Jake Dalton factor into it?

They found Jake's body.

What are we going to do?

I don't know.

We just have to keep quiet, Rose.

That's all we can do right now.

Hey, I'm home.

Hey, I'm out here.

How was your day?

Oh, you know, fine.

Nothing special to report.

How was yours?

Yeah, same. Just had a video call with work.

Boss was so jealous of the view and she met Harry.

Totally fell in love with him.

Where's your tie?

Oh, the talk l did at the school - there was a little girl said

she could do magic tricks.

She couldn't.

I'll get you a beer!

Thanks.

So I was thinking we could invite your team over for dinner one night.

What do you think?

Yeah, sure, why not?

Well, it's just, I hardly know them and they are your friends.

Plus, it'd be nice to host a dinner party together...

Wouldn't it?

We should definitely do it.

So you'll speak to them?

I will speak to them, promise.

Oh, Darlene, good morning.

Oh, you're late.

I most certainly am not, it is bang on 8:30.

I'm just messing with you.

It's a little welcome back joke to start the day.

And what a beautiful day it is.

Well, you're in better spirits than I was expecting.

You feeling better about your exam results?

You know, a few days off work and I tell you, I'm feeling tippity top.

I'm putting the past behind me, and I'm focusing on looking forward.

The future is calling to me, Darlene.

And you know what it's saying?

What?

It's saying, "Marlon, you're welcome here."

Come on inside, come.

Officer Pryce, have you been drinking?

I'm just drunk on life, Darlene.

Drunk on life.

Morning, sir.

Oh, Marlon, welcome back.

Happy to be back, Inspector.

Sarge.

So the postmortem is in, and it confirms that Jake Dalton

was killed by a single blow to the head with a heavy object.

And we think we know what it was.

When Darlene and I finished processing the bedroom last night,

we found significant traces of blood on this paperweight.

I sent it to the pathologist, and he's going to confirm

whether it's a match for the wound.

We also checked Jake Daltonts boat and found further traces of blood.

So that's definitely how the killer disposed of the body at sea.

Used the victim's own boat.

And is the wife a suspect, sir?

Well, she's definitely hiding something, but according

to the postmortem, time of death is somewhere between

10:00 and 11:00 yesterday morning.

And Rose Dalton claims that she was working at that time.

She says the client whose house she was cleaning can confirm

she was there from 9:30, but we need to verify that alibi.

Mm-hm. Also, there's this...

Yeah, I saw the letter, sir.

Whoa! Right?

Well, seriously, I mean, whoa!

Yeah, eloquently put, Marlon.

What I'm struggling with is if Rose Dalton did kill her husband,

why the hell would she send a letter saying she was going to do it?

It just, it doesn't fit, it doesn't make sense.

OK, so what do we do, sir?

Well, let's start with what we do know.

Jake Dalton's body was discovered here.

Now, the winds were low yesterday, and the currents were minimal,

so it won't have drifted far from where it was initially dumped.

That means the killer must have travelled

from here, this jetty, to somewhere in this area.

Can you both hit the harbours and marinas and see if anyone

was in this stretch of water yesterday morning? If they were,

they might have seen who was driving Jake's boat.

There's a lot of people that own boats on this island, sir.

I mean, that's going to be a fair bit of asking around.

No, Darlene, that's just being defeatist.

You're better than that.

We will do whatever it takes, Inspector.

Don't worry.

Um...right.

OK. Thanks, Marlon.

While they're doing that, we need to check Rose Dalton's alibi.

Yep.

I don't think he's in, sir.

No. Excuse me.

Can I help at all?

Mr Cartwright?

That's me.

Detective lnspector Neville Parker.

This is Detective Sergeant Thomas.

Nothing wrong, I hope.

We just wanted to ask you a couple of questions about Rose Dalton.

My cleaner?

Perhaps we could go inside?

Yeah, sure.

Is she all right?

Rose, I mean.

We'll explain once we're inside.

What's this all about, then?

Mrs Dalton's husband was found murdered yesterday.

Oh, God, that's just awful.

Poor Rose. She must be heartbroken.

Did you know Mr Dalton at all?

Not really. I'd occasionally see him

when he came to pick Rose up after work, but we never met.

Oh, they seemed so happy together.

What makes you say that?

Just how they were, affectionate with each other.

We need to rule Mrs Dalton out as a suspect.

She claims she was here yesterday morning between 10 and 11.

Is that right?

Same time every week. She got here about 9:30, I think.

Left about one. And she was here the whole time?

You're sure about that? Positive. She was here all morning.

I mean, you can't seriously be thinking

Rose had something to do with this, do you?

We're just covering our bases, Mr Cartwright.

Why don't I give you my phone number?

If you need to get in touch about anything...

That would be great. Thank you.

Thank you.

So if Rose Dalton is not our killer, then who is?

I mean, we're not exactly drowning in suspects at the moment.

Sir?

This envelope.

It's the same kind as the one I received in the post yesterday,

containing the letter. Everyone has envelopes, sir.

Does everyone have cream-coloured envelopes? Er...

lt's just an envelope. Could be anyone's, I guess.

Inspector?

Yes?

I'm sorry. I'm not sure that I should...

It's just, er...

Go on.

I saw this.

That's not Rose's husband.

I mean, it obviously must be,

but that's not the man I've seen with Rose these past few months.

Are you sure it's not the same person? Positive.

And this other man,

he and Mrs Dalton were affectionate with each other, you said?

They looked like a couple.

His name is Henry Baptiste.

He's a teacher at the Adult Education Centre in Honore.

That's where we first met.

Were you working there or studying?

I started a course there about six months ago now.

It was something to get me out of the house.

I'd just got so bored of us arguing.

So was Mr Baptiste your tutor? One evening after class,

we all went for a drink, and Henry came too.

We got chatting, and. . . it became more of a regular thing,

me and him going for a drink after class. Just us.

And after a while, it became more than just a drink.

And the affair's been carrying on ever since?

I can see how this looks to you. And nothing that's happened,

me and Henry, it doesn't mean I'd want Jake dead,

that I'd kill him. Yes, Mrs Dalton.

But in the last 24 hours, since Jake's body was found,

you've lied to us and changed your story twice.

It doesn't look good. I know. I'm sorry.

But the one thing I never lied about is that I didn't kill my husband.

We'll be in touch.

It's the first time she seems like she's actually being honest.

Yeah.

But now we have a secret lover, Henry Baptiste.

Let's see what we can find out about him. I'll do some background, sir.

"A murder will be committed today."

Why let me know that?

Why me?

Sir.

We've got the results from the lab on the letter and envelope.

And? No prints, no DNA,

absolutely nothing they could find to trace this back to the sender.

I guess whoever sent it was very careful about it. Yeah.

They knew exactly what they were doing.

OK, sir. We have been to Honore harbour, Port Royal harbour,

the marina down near Sunny Bay, and the marina up at St Lacroix.

We spoke to fishermen, boatmen, jet skiers.

And I'm afraid, sir, not one of them could help us.

No-one was out near where the victim's body was found

yesterday morning. Well, at least you gave it a good go. Thanks.

However...!

There's a however? There is always a however

when Marlon is on your team, sir.

So, I put out a call

to one of my old associates, Alphonse.

He used to poach turtle eggs back in the day.

You know that's really illegal, right?

I said, used to, sir. He gave up poaching.

Alphonse is a changed man now.

Also, the environmental department installed cameras to monitor

the turtles nesting across this stretch of beach here.

That's right along the route the killer dumped Jake's body.

Exactly.

I've arranged for us to have access to the footage tomorrow morning.

Ah-ah! Get you !

That's some good thinking. Yeah. Very well done, Marlon.

Yeah, well, you know, it's just what I do.

Good evening, everyone! Hey, Catherine.

I hope you don't mind me interrupting,

but I just stopped by to give you this.

Spicy creole fish stew?

Why are you giving me a recipe?

For Sophie!

She wanted to cook something local.

For the dinner party tomorrow? Oh! You're having

a dinner party, sir? Yes. Yeah, and you're all invited.

Oh, thank you, sir.

I can't wait. l was supposed to invite you earlier, but I ...

With the case and everything, I totally forgot.

Can you make it?

Of course I can, sir. It sounds fun.

Marlon? What? Free food? Try stopping me.

Well, I shall look forward to seeing you all there. Great.

Oh! Catherine! Catherine...

Um...exactly how spicy is this spicy fish stew?

Very!

I knew you were going to say that.

Bye!

Bye, Catherine!

So, what exactly went on while you were on leave?

Wasn't expecting you to come back so upbeat after...

...you know, what happened.

I, um, I went to visit JP,

you know, my old boss. Mentor.

I went to spend a few days with him and his family.

Sounds like a good call. What did he have to say about it?

That I wasn't ready to be a sergeant.

But he has no doubts that one day I will be, soon.

In the meantime, just focus on being the best police officer

that I can be.

It sort of made sense, actually. Which is pretty much

what the commissioner said to you in the start.

Yeah, I guess.

Do you think you maybe owe him an apology?

I was kind of hoping it wouldn't need saying, you know?

He's going to have me for breakfast, isn't he?

Yeah.

Night!

Morning, Commissioner. Inspector.

I thought I'd check in with you regarding Jake Dalton's murder.

We've got a few potential leads, but nothing definitive.

Mm-hm. And the letter?

Have you made any more sense of that?

Not really, sir.

Less sense, if anything.

Mm. There is one thing, actually, while I 've got you here.

I wondered if you'd ever come across

David Cartwright.

Lives on Saint Marie. He's loosely connected

with the victim's wife. She cleans for him.

Should I have? Well...

...it's just that he was a criminologist back in the UK.

Very respected in his field.

Helped out the Met with a few high-profile cases

before he stepped back from it all a couple of years ago.

He actually had this book published in the early 2000s.

I only found out when I looked him up.

I just... l just find it odd that he didn't mention

any of this, himseff, you know?

So are you suggesting we seek his advice on this case? No!

No, no, I'm saying...

l don't really know what l'm saying, to be honest, it just...

lt just doesn't sit right with me, that's all.

I couldn't really tell you why.

Go with your instincts, Inspector.

But... I don't think you needed me to tell you that.

Thank you, sir.

Morning, Naomi. Everything OK?

OK. I'm on my way.

Darlene and I spoke to a couple of Rose's classmates at the college.

Turns out everyone knew what was going on with her and Henry.

And apparently he was getting impatient, wanted her to leave Jake.

Hated the fact that she still had feelings for Jake.

So Henry was jealous.

So, this beach is rigged for surveillance.

It's got motion-sensing cameras on the ground over there.

They're dotted all along the coastline.

That security camera is used to deter poaching.

And the good news is, sir, it's rolling 24�7.

Hmm.

We've gone through the footage, sir.

This was taken between 10am and 1pm on the day of the murder.

Fortunately for us, whoever was disposing of Jakets body

came close enough to the shoreline to be caught on camera.

What time was this? Just gone 12.

Oh, so it fits with our timeline. Fits perfectly.

And sir, it's Jake Daltonts boat.

Sir.

That's Henry Baptiste.

I didn't kill him. I swear.

It's. . . It's really not how it looks.

We've heard you were getting frustrated with Rose

because she wouldn't leave Jake for you.

Who told you that?

Because she still loved him.

No.

No. The man was a loser.

Earned nothing from that boat of his.

Gambled away any money he made.

She deserved better than him.

And I could give her that - a better life.

And with Jake dead, you'd get exactly that.

Exactly what you want.

Look, I didn't kill him, OK?

But. . . I was there that morning.

I went to their home.

I was worried. Worried about what?

I got a message from Rose

saying that she and Jake had had a massive row.

She sounded so...

. . intense.

It's me.

I've done it.

I've ended it, once and for all.

I'm not sorry.

I didn't know what she'd done.

And that's what led you to their house?

I went to check, make sure she was OK.

But when I arrived,

Rose wasn't there, and...

And Jake was already dead.

I saw a paperweight lying on the floor,

and there was blood.

And I thought...

. .what has she done?

So what did you do?

I can't explain it.

I've never done anything bad in my life.

But I just wanted to help her.

Protect her. So...

. . I moved the body.

Outside, and into the boat.

So you took the boat out, disposed of the body,

and came back and cleaned the place up?

But there's something else you need to know.

And I need you to believe me.

I got it wrong. I got it all wrong.

Got what wrong? It wasn't Rose who killed Jake.

I went to see her at work that same day,

and when I told her what I'd done...

It really wasn't you?

. . I could see in her eyes she was shocked, shaken.

On both our lives, she didn't do it.

This way, please.

Henry? It's me.

I've done it.

I've ended it, once and for all.

And I'm not sorry.

We need to talk to Rose ourselves.

Find out what she claims happened that morning.

Thank you.

Inspector. Yeah.

That was David Cartwright on the phone.

He wondered if he could have a meeting with you.

What did HE want?

Said he wanted to talk to you again about Rose Daltonts alibi.

Said it was important.

OK, well, why don't l go and speak with him

and you go talk to Rose? Sure.

You wanted to see me?

Yes. Please come through.

I'm so sorry to be troubling you like this, Inspector.

I appreciate how busy you must be, especially with a murder to solve.

It's fine. How can l help?

I've, er, been a little remiss

in what I told you and your colleague.

In what way?

I said that Rose was here all of yesterday morning.

But if I'm being honest, I can't 100% say that that's the case.

You mean she left the premises? I don't think so,

but I can't wholly be sure.

Between 10 and 11, I was on a video conference call

and I assumed she was still here cleaning.

But... You didn't actually have eyes on her? No.

I can only think the best of Rose, and I ...

I wrongly put that ahead of giving you the honest facts.

I still refuse to believe

that she'd be capable of something like this.

Killing her own husband.

It makes no sense at all.

Well, l guess you would know.

Right?

This is your area of expertise, isn't it?

Ah.

Someone's been busy Googling.

I was hoping I could keep that to myself.

Yes, l have to say, l did find it a little odd you didn't mention it.

Well, there was no offence intended. It didn't seem relevant, really.

It's not like I can consult on a case like this,

not with me being involved in it.

Involved in it? You know, providing an alibi for Rose.

Or not, as it turns out.

Anyway, I don't consult on active cases any more.

I've stepped back from all that.

It's why I moved out here a couple of years ago.

I needed a change of perspective.

Right.

Well, look, I won't take up any more of your time.

And apologies again for not being straight up about Rose.

It's fine.

Really. I'm sure we can still get to the bottom of it all.

Let's hope so, eh?

What is your game, Mr Cartwright?

Oh! Oh! Oh, sorry, sir.

I was just heading off to get ready.

Get ready?

For your dinner party, remember?

Yeah, of course.

You go. How'd it go with David Cartwright?

Well, it seems he can no longer alibi Rose Dalton

for the time of the murder. That's strange. Yeah.

It's a bit of a U-turn. You would think he'd know better,

having worked on cases himself.

You would.

Hmm. Well, Rose Dalton admitted she told Jake she was leaving him

the morning he was murdered.

That's why she left that voicemail.

You've taken it all, Jake.

She discovered he'd helped himself to her savings,

blew it all in a poker game. Look, I'll get it back, all right?

I'm going to get it back. You promised !

That's what the argument was about.

But she still insists she didn't kill him.

I'm not sure she did.

Really?

So who do you think did it?

Let me get back to you on that one.

I'm still processing.

I'll see you at dinner.

No prints, no DNA,

absolutely nothing they could find to trace this back to the sender.

They knew exactly what they were doing.

He was a criminologist back in the UK,

helped out the Met with a number of high-profile cases.

He'd know exactly what he was doing.

Thank you.

Oh! Commissioner.

Good evening, sir. It's a pleasure to see you.

How are you keeping yourself these days?

Good evening, Officer Pryce.

And...this is for you, sir.

It's vintage. The second most expensive rum on the menu.

The one above was a touch out of my price range.

So, here we are.

Just me and the big man himself.

Do get on with it, Marlon.

Right. Um...

... I 've invited you here because there's something I want to say.

Something I need to say. You're sorry.

Good. So you should be.

Glad to see you've seen the error of your ways.

That was much easier than I expected. However...

I knew that was coming.

...the growing trust I had in you as an officer has been damaged,

and it's going to take more than a glass of vintage rum to repair it.

You don't trust me any more, sir?

When you revert to the kind of cocky teenage arrogance

you displayed when you first joined us,

it feels as if we are going backwards.

Not forwards.

A good police officer needs to be consistent

in their performance, and dependable.

After three years, I'm sorry to say,

you still seem to be lacking both those qualities.

Good evening, Officer Pryce.

Wait, Commissioner.

You're right.

You're right. And I really, really am sorry, sir,

but I am going to do everything I can to earn your trust back.

You'll see.

Hmm.

Hey.

Evening.

Did he have you for breakfast?

And lunch and dinner as well.

Are you OK? Yeah.

I reckon I will be.

Here.

You need it more than me.

OK? Yeah.

Is everyone all right for drinks?

Mm-hm. Yes, thanks. All good.

Right, well, just help yourselves.

Food's nearly ready.

Just...

. .waiting for Neville to arrive.

Oh, why don't I phone and chase him?

Well, I have text him.

He just hasn't got back. Oh, leave it with me.

No, no. I know Professor Cartwright

doesn't work there any more. I'm just trying to reach out

to one of his ex-colleagues, a Professor Karen Wilson.

Yes, l know. l understand it's late. I'm sorry.

Just please pass her my number.

Thank you. Bye.

Knock, knock.

Mr Cartwright. Oh, David, please.

I brought you this.

Must have fallen out of your pocket at my house. Oh!

Well, I'm sorry you had to come all the way over here.

Oh, no problem at all. I was passing.

Well, I hope that doesn't mean I'm a suspect now, Inspector.

No comment.

Actually, maybe there's something you should take a look at,

since you're here. Might interest you.

We received this in the mail on the day Jake Dalton was killed.

"A murder will be committed today."

Not unprecedented. There is a history of murderers

who make themselves known to the police. Mm.

What kind of person would send such a thing, do you think?

As I already told you, I don't consult on cases any more.

Mmm. But tell me what you think.

Oh, l reckon the killer would be, er...

...intelligent.

Forensically aware.

Probably enjoys being in control.

Dominant. Hmm. Not bad.

Problem, of course, Mr Cartwright,

is the only person on my incident board

who fits that profile is, er...

Well, it's you.

Yes, I can see that.

But I hate to have to point it out - I have an alibi.

I was at home.

Ah, yes. The video conference call.

Well, it was more of an online O&A with some students.

Might interest you, actually. I'll send you a link.

Thank you.

You look a little tired, Inspector. Are you coping all right?

Why wouldn't l be?

Well, case like this, receiving a letter like that,

it can take its toll. Mentally, emotionally.

I'm fine, thanks.

Well, I'll leave you to it, then. I can see you have...

...lots to be getting on with.

Oh, I meant to say, there's some missed calls.

I think someone's trying to get hold of you.

Oh, no. I'm in so much trouble.

Hey, Sophie, I'm so sorry. I got held up at work.

Is everyone still there?

OK, I'm leaving now. OK, bye.

I'm just curious, Professor Cartwright.

What first drew you to a career in criminology?

As with so many things in life, there was no single defining moment.

I suppose from a young age, I was fascinated with why people

choose to do bad things.

Is that him?

I know he did it, Soph. l know it.

But every corner l turn, it's like there's a trap laid for me.

Look at this alibi. It's perfect.

He's live online at the exact time of the murder. Hey!

Hey.

I'm worried he's getting to you.

I've never seen you like this before.

I'm sorry.

Dl Parker.

Professor Wilson! Yes. Yes, I did leave a message for you.

Thank you so much for calling me back. Um...

Yeah, look, l just wondered if I could maybe ask you

a couple of questions about an ex-colleague of yours.

Mr Baptiste has been taken to the courthouse

and will be released on bail. Thanks, Darlene.

So this guy is a suspect now?

Yep.

Makes sense, right?

Got two suspects here, both up to their necks

in means, motives and opportunities. But no, the inspector thinks

it must be the respected criminologist that did it.

I know what it looks like.

And l understand your doubts. Both Rose Dalton and Henry Baptiste

had good reason to want Jake Dalton dead,

and their alibis are weak. But...

...what they didn't have good reason for was to send me a letter first,

announcing their intent to murder.

Whoever wrote that letter wanted to play a game

with us. And from the moment David Cartwright crossed our path,

he has continued to tease and toy with us,

dropping hints and clues

and at the same time obfuscating and misdirecting us.

She got here about 9:30, I think.

But if I'm being honest,

I can't 100% say that that's the case.

Leaving a trail of breadcrumbs that could only lead to one conclusion.

Only person on my incident board who fits that profile is...

Well, it's you.

He murdered Jake Dalton. But, Inspector,

you're saying that he wants us to know that he did it?

Mm-hm. That's crazy, sir.

Why would he want to get caught?

Oh, he doesn't want to be caught.

He doesn't believe he will get caught.

That's why he's doing all this, relishing every moment,

because he so profoundly believes that we will not catch him.

But why Jake Dalton? I don't understand.

What's the point in killing him? He's never even met the man.

We never met.

He has no motive to kill him.

There is no motive. That's the point.

He has no reason to kill a total stranger.

It's just murder for murder's sake.

So you're saying that he murdered

another human being just for kicks?

Yep. Because he wanted to prove that he could.

To who?

Well, l think the answer to that

lies in David Cartwright's past, before he came to Saint Marie.

I spoke with an ex-colleague of his and asked why he gave up

his professorship, why he gave up his gilded status

as one of the UK's top criminologists.

What did they say?

That they were worried about him, a couple of years ago.

His peers and associates.

They'd noticed a change in him, said he'd become

overly focused on a particular case, a series of murders.

The killer had been arrested, and David felt that the only way

to truly understand what had happened was to

spend as much time as possible interviewing the perpetrator.

So, what happened?

He got too close.

The lines blurred.

In trying to empathise with the killer

and understand what he'd done,

Cartwright kind of lost his bearings.

It was suggested that he seek counselling, but he never did it.

He didn't see a problem. But he was forced

to step down from his professorship and consulting jobs,

and he did not like that one bit.

Didn't like being told what to do, felt demeaned.

And so he came to Saint Marie bitter, resentful, and vengeful.

I just can't find the final piece of the puzzle -

how he did it. Because between 10 and 11 o'clock,

while Jake Dalton was being murdered,

David Cartwright was being recorded at home for the whole world to see.

Because, of course, there's a clear distinction between those who murder

in the heat of the moment

and the more ruthless, cold-blooded, premeditated killer.

And that needs to be considered when profiling a suspect.

There needs to be a considerable change of perspective.

He's said that before.

Sorry, sir?

...profiling a suspect.

There needs to be a considerable change of perspective.

A change of perspective.

Needed a change of perspective.

Why's he saying that?

I hate to have to point it out - I have an alibi. I was at home.

We just found our crime scene.

That's it. That is exactly it.

You know how he did it?

I've found it. The final piece.

So, what do you want us to do, sir?

We need to get a search warrant for David Cartwright's house.

Let's see if we can turn the tables on him.

Beat him at his own game.

Inspector?

What are you doing in my house, Inspector?

You know, l always thought it was impossible

to be in two places at once, Mr Cartwright,

but now l realise l was entirely wrong on that count.

Because you see, while it may appear that I'm sitting in your study,

l am, in fact, in the room right next door to you.

In Mr and Mrs Dalton's bedroom.

See?

Just like you were the other day, when you murdered Jake Dalton.

So am I officially a suspect now?

Oh, l'd go so far as to say you're our prime suspect, Mr Cartwright.

Because l know you did it.

Oh, goodie.

Let the fun begin, eh?

It was a brilliant illusion.

Simple, like all the best magic tricks.

And it was executed with precision timing.

Bravo.

On the morning of the murder, Rose Dalton came to clean your house

at 9:30am, like she did every week.

Morning, Mr Cartwright.

Morning, Rose.

Now, from previous conversations with Rose,

you'll have got some idea of her husband's routine.

He had the same routine most days.

That he liked to pop home for breakfast most days.

Came back here for some breakfast at nine.

So you knew that while Rose was busy cleaning your house,

Jake would be home alone.

Having told Rose that you'd be busy in your study on a video call,

so knowing she wouldn't disturb you,

you headed over here to their house,

and at around one or two minutes to ten o'clock,

you entered this bedroom...

...and you murdered Jake Dalton.

You then dropped the murder weapon

and quickly prepared the room for your video call,

so that everyone who was watching

the live question-and-answer session

would assume that you were in your study.

As with so many things in life, there was no single defining moment.

Whereas in fact,

you were still right here at the crime scene,

with Jake Dalton's dead body right in front of you.

I suppose from a young age, I was...

...fascinated with why people choose to do bad things.

When you'd finished your video call,

you packed all the belongings from the study into the car

and made your way back home, slipping back in

without Rose seeing you,

safe in the knowledge that you'd provided yourseff

with a seemingly unbreakable alibi.

Well, it's certainly a compelling theory, Inspector.

It's more than that, and you know it. We both know it.

Game's over, Mr Cartwright.

It stops now.

Let's say I did do it, exactly as you've just said.

One question.

How are you going to prove it?

We've processed the crime scene thoroughly, the whole house.

The lab's testing for traces of your DNA right now,

and they will find it - proof that you were in this room.

Yes, you're right.

You will find my DNA here.

You see, I have been in this bedroom before.

About a week ago, I think it was,

I changed the locks to my house,

so I came round to drop off a set of keys for Rose.

Sorry. I did knock. Oh!

New set of keys.

I'll just pop them here, shall I? Er, yeah.

So you see, Inspector, DNA is not going to cut it in court,

is it?

It was a very good try, though. But...

...no cigar, as they say.

You killed an innocent man for no good reason.

You won't get away with that.

I'm afraid I have to go.

There's a bit of a bash being arranged for me in my honour.

They're re-issuing my book, you see - Murder In Mind.

Did I mention it?

Signing at the Manda Bay Hotel, and some little festivities.

You know, it's been a quiet couple of years for me,

out in the wilderness...

...but it's starting to feel like it might be my time again.

Goodbye, Inspector.

Neville?

Is everything all right?

He's going to get away with it.

What? David Cartwright.

He's going to literally get away with murder.

But...he can't. He did it.

You said he did it.

What is that? No, no, no, no.

This ends now.

He's not going to do this to me.

I can't. I can't let him do this to me.

I won't let him. I will not let him do this to me!

Neville, stop.

No! Wait! l am going to put a stop to this right now.

David Cartwright's room.

Yes, of course. Room 19.

Cartwright, we need to talk.

Come on, open up. I know you're in there!

Hey!

Are you all right, Inspector? You don't seem yourself.

I've had enough of your games, Cartwright, so you can drop me out.

We both know the truth. I know what you did...

Sorry. Excuse me.

Sorry. Coming through, please.

Let the commissioner through, please.

Thank you.

Thank you.

It's this way, sir. All right.

Sir, it's David Cartwright.

Where's DI Parker?

There's something else you need to see, sir.

On CCTV.

I'm really worried. He was so angry,

and now he isn't answering his phone.

He hasn't come back to the shack. I don't know what to do, Catherine.

Come. Let's go find the others, mm?

Julian, I've got to go. I'll be back as soon as I can.

Neville Parker,

I'm arresting you on suspicion of the murder of David Cartwright.

Selwyn, what's going on?

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

if you do not mention when being questioned

something which you later rely on in court.

Anything you do say, may be given in evidence.

No, wait.

It can't be right.

I - I don't understand.

You can't have.
