10x02 - Steamy Confessions

[bunniefuu]

I knew it! Look, Ed.

The key landmarks match his account exactly.

We need to shift the entire dig north-west to here.

Well, good luck selling that to the prof.

Yeah.

Hello?
Hello?
Is anyone there?
So creepy.

Sorry to interrupt, Roger.

I didn't know if you'd want something to eat, too.

No, I couldn't stomach anything solid.

I've still got this damn bug.

And I've had to redo the entire grid because Ed's measurements are out.

How he ever got accepted for a PhD is beyond me.

I thought you should see this.

I took it this morning, and if you compare the topography to this description in Alva's letters No, I thought we were past all this.

If you just read what Alva says.

It really is astounding.

For the last time, any self-respecting archaeologist knows that Father Oscar Alva was a nutty Victorian fantasist who penned these letters in his Mayfair townhouse.

If Alva had the same technology we have, he'd have found the temple.

And, frankly, I think that we'd be negligent Yes, you've made your point, Rebecca, but if you think I'm going to relocate the dig based on this nonsense, you're out of your mind.

Thanks for the coffee.

Come on.

What did you expect, eh?
The prof was never going to go for it.

Don't let him rattle you.

So closed-minded.

I know.

He's old-school.

A relic, like this dude.

Don't worry.

His type'll be extinct soon enough.

Tell you what, he doesn't look well.

Good.

No, I mean, really ill.

Help me! Yeah, just there.

Thanks, Rudy.

See you tomorrow.

Thank you.

DS Cassell.

Hello.

How are you?
Fine, thank you, sir.

Glad to see all the fire damage has been repaired.

Yeah.

The Commissioner was kind enough to take care of it for me.

Seems very generous of him.

Yeah, I thought so, too.

What are all these parcels?
I'm replacing all the stuff I lost in the fire.

Look at that, 35 hours of Worid w*r II.

Sir, I thought your plan was to participate more in island life, not just go back to how you were.

Yeah, sure, as and when the opportunity arises.

Well, I think that the opportunity might be here.

The Saint Marie Crab Festival?
It's an annual event.

People come from all over.

I think I'll pass, thanks.

I'm not very keen on crabs.

You're allergic?
No, surprisingly.

They just give me the heebie-jeebies.

No.

JP.

The deceased is Roger Harkness, a professor of archaeology at UCL.

He collapsed in front of his colleagues around lunchtime.

They're digging up in the hills.

Sounds like they've been there a few weeks.

You know, Florence, I used to be something of an amateur archaeologist myself.

Really?
I was given a metal detector for my ninth birthday.

Best present ever.

Sir.

Sarge.

JP.

Bad night?
Horrific.

We had four noise complaints, two people locked out of their houses and one person who couldn't take a taxi so decided it was my job to drive them home.

Honestly, the sooner we get a new officer, the better.

Any idea when that might be, sir?
I'll check in with the Commissioner.

He says he's working on a plan.

So, this is Professor Harkness?
Yeah.

He was sitting there when he d*ed at 12, According to his colleagues, he was feeling unwell for the last few days.

That's interesting.

Strong odour of garlic emanating from the victim.

Either he was trying to ward off vampires or he was the victim of Arsenic poisoning.

When arsenic is metabolised in the body It transforms into methylated compounds.

Often resulting in a garlicky aroma.

Apparently, Victorian wallpapers used to stink of it.

Black coffee.

A fatal dose of arsenic takes 30 minutes to act.

Can we assume those are the professor's colleagues?
Yes, sir.

DI Neville Parker.

This is DS Cassell.

I'm Rebecca Assistant Professor Rebecca Morley.

I work with Roger at UCL.

Worked.

I'm Ed Lancer.

Sorry, I'm just struggling to take it all in.

Roger was my mentor.

Yes, we're very sorry for your loss, but we do need to ask you a few questions.

Yeah, of course.

Do either of you know what the professor ate in the 30 minutes before his death?
Nothing.

I offered.

I didn't know if you'd want something to eat, too.

No, I couldn't stomach anything solid.

He hadn't eaten anything for a couple of days.

He had a dodgy tum.

A bug or something.

Who made the coffee on his desk?
That was you, wasn't it?
Yeah, I So you brought him a coffee, he drank it, sitting there and about half an hour later he was dead?
Well, yeah.

And he was sitting at his desk the whole time?
No-one else entered the tent?
We should have made him see a doctor.

We had no idea there was anything seriously wrong.

Was the coffee fresh or instant?
Instant, but I don't understand why And we know he drank it black, but did he take sugar?
Why is this relevant?
Because if what you've told me is true and he didn't have anything to eat in the last 24 hours, then I strongly suspect Roger was the victim of arsenic poisoning.

I never meant to k*ll him.

I was so careful.

Literally giving him trace elements.

I just wanted to make him sick enough to fly home or, at the very least, to hand over the reins.

Why?
I spent weeks looking for the Arawak temple and I discovered these letters by a 19th-century missionary, Oscar Alva, which suggested we were looking in the wrong place.

What do these letters say?
He'd been doing his own excavations.

They're full of what I believe are clues.

But the professor wasn't convinced?
He dismissed Alva as a crank.

So, in a nutshell, you'd been poisoning his daily coffee because he wouldn't let you have your own way?
No! No, this wasn't about me.

This was about our work.

This could be a site of global importance.

You've no idea how hard it is, scrabbling in the soil, day after day, knowing we're just wasting our time and all the while living on top of each other.

Enough to make anyone lose their mind.

Rebecca Morley, I'm arresting you for the manslaughter of Roger Harkness.

Sir.

I found this in her tent.

Is that the poison you used?
I'm curious as to how you came by a vial of arsenic halfway up a mountain.

I was charting the site one day when I stumbled across this old shed.

Who does it belong to?
The Joyces, I presume.

They're the people who own the land.

Mother and son.

It was empty, apart from some old junk, and I spotted this ancient-looking flypaper.

And old flypaper contains arsenic.

So you had an idea.

I soaked the paper in some water.

Boiled the solution down.

And for the last week or so, I've been putting a minuscule drop in his coffee every day.

Are you sure, Julius?
He's definitely dead.

They put him into one of them bags and the police are taking a woman away.

They think she did it?
Looks that way.

And they didn't see you, the police?
No.

At least we'll be left in peace now, right, Mum?
Let's hope so.

Thank you.

All right, so Rebecca's confirmed these are the flypapers she extracted the poison from.

That's great.

That means we've got the k*ller and the m*rder w*apon.

Congratulations, Inspector.

You know, for a man of your stature, sir, you have a surprisingly light footfall.

To what do we owe the pleasure?
You asked me whether there'd been any progress in finding our new officer.

Have we found someone, sir?
I'm putting together an application for the PCPRSFYO.

And what is the PC C-3PO whatever it is, sir?
The Pan-Caribbean Police Recruitment Scheme.

I shall have a shortlist by the end of the week.

Well, that's great news, sir.

I almost forgot.

A bill.

For the repair of the fire damage to the shack.

I thought it was too good to be true.

He hates me.

The Commissioner has an unusual manner, that's all.

It's not personal.

I just wish he and I could find one thing in common.

We're never going to be best mates, but if I could get him to respect me just a tiny bit, then I have to ask why are you so scared of crabs?
Why are you not?
! You really don't need to know.

I really do.

OK, well, I was on a date A date?
Yes.

I Catherine's here.

The story'll have to wait.

Our island's famous crab callaloo.

Gosh, that looks distinctive.

Can I ask what's in it?
Well, that depends who you ask.

Every family has their own recipe, each one a closely guarded secret.

And every year, we all compete to see who can produce the best crab callaloo on the island.

Isn't it true that you Brits love your cooking competitions?
Yeah.

There's nothing more British than watching a cooking show whilst eating a takeaway.

Then maybe you should think about entering.

I really don't think I'm qualified.

Seems the perfect chance for you to really get involved with island life.

Well, I don't I don't suppose it could do any harm.

I'll get you an application form.

OK.

But I-I'm sorry I don't suppose I could just swap this for chicken and chips, if it's not too much trouble?
All the physical evidence that we have uncovered suggests that the Arawaks were a sophisticated and complex culture.

Sir, the lab results are in, and let's just say things aren't as simple as we thought.

Yeah.

Postmortem reports confirm Roger Harkness d*ed from arsenic poisoning.

As we suspected.

But we have no idea where the arsenic came from.

The coffee tested negative for arsenic.

How?
That was the only thing he consumed in the half-hour before his death, and Rebecca herself said she put the poison into his coffee.

Yeah.

Her vial of arsenic also tested negative for arsenic.

The labs dated the flypaper back to the 1960s.

They think all the chemicals and poison would have leached out of them by now.

Yeah, I suppose if it'd been sitting in a damp shed all those decades, that would make sense.

So, hold on, Rebecca thought she was poisoning the professor, but it turns out she wasn't?
Exactly.

But what about his illness?
That can't have been a coincidence.

The solution in Rebecca's vial contained traces of E.

coli bacteria, which, according to this, probably transferred from the surface of the flypaper.

No, no, no, no! Come on.

This doesn't make sense at all.

Cause of death was arsenic poisoning, but the poisoner didn't poison him?
And if Rebecca's little experiment didn't work, then where did the arsenic come from and how the hell did it get into the professor's system when the only thing he consumed in the half-hour before his death was that coffee?
! Sir, where does that leave us with our suspect?
We might have a sh*t at aggravated as*ault, but with no evidence that she k*lled the professor, I have to release her on bail.

So, either she's the k*ller and this is all just some kind of double bluff Or the real k*ller knew what she was up to and used it to their advantage.

By giving the victim an extra dose to k*ll him, safe in the knowledge that the evidence would lead us straight back to Assistant Professor Morley.

I think it's time we did a bit of digging on Sr.

Ed Lancer, don't you?
OK, two things are bothering me.

One, arsenic is notoriously hard to come by.

Most of its commercial use stopped years ago, so how on Earth did our k*ller acquire it?
And two, if the professor didn't eat or drink the fatal dose, then how else did he ingest it?
There's nothing else consumable on there.

Just a map and a journal.

And he definitely wasn't a smoker?
Apparently not, sir.

This was everything that was on him at the time of his death.

Hanky, cash, glasses and a glasses case.

No packets of mints or sweets?
This was underneath the table where he was seated.

I had a look through it yesterday and there was no food items in there.

Two bottles of factor 50, a spare journal, one ruler, a second ruler, a pakamac, and another pakamac.

Seems like Professor Harkness liked to be prepared for all eventualities.

A man after my own heart.

But there's certainly nothing else here that he could have ingested .

.

unless he lost a bet and had to eat his hat.

DS Cassell, did you manage to run that check on Ed Lancer?
Yes, sir.

Nothing came up apart from this, his social media page.

«Join me, Intrepid Ed Lancer, «as I hunt down the past across the globe.

» He has over 50.

000 followers.

And apparently a showbiz agent.

Look.

You might want to look at this, sir.

It's on Roger's mobile.

Roger, what are you doing here?
I knew that you were up to something.

Hand it over! When was this taken?
The day before the m*rder.

Any idea who the other man in the footage might be?
Yes, it's Marlon Pryce.

19 years old and has run every scam going, and somehow always seems to get away with it.

Not this time.

You've got him on camera.

Maybe you should track this Marlon down.

With pleasure.

I've got all the latest titles.

Top quality.

You know, some of these aren't even in the cinemas yet.

Some of these haven't even been made yet.

After two minutes, you won't even $10 each.

But, since I'm in a good mood, I'll do two for 20.

Have a lovely day, sir.

Ladies, ladies, two for 20.

Marlon Pryce.

Officer Hooper.

Nice to see you again.

Your latest hustle?
Pirate DVDs?
These are 100% legit.

I'm just trying to earn an honest living.

You don't know what the meaning of «honest» is.

And it's Sergeant Hooper now.

You got a promotion?
Good for you! Anyway, I'm not here about those DVDs.

I'm here about a m*rder.

Well Oye! Excuse me.

I knew that you were up to something.

Hand it over! I swear down, Sarge.

I don't even know who he was.

Just some tourist or something.

He just asked me to post a parcel.

That's all.

Well, if that's all, why would the m*rder victim film your little exchange?
Nope.

I got nothing.

How many outstanding warrants you got, Marlon?
Because every minute I'm standing here, those warrants are rising up my to-do list.

OK, OK, look, I'll tell you the truth.

All that happened was this guy had came to me and asked me to help him get some stuff off the island.

Yeah?
What kind of stuff?
Just some coins.

Seemed like an easy enough job, so I said, «Sure, no problem.

» Anyways, we meet at this bar.

I get my fee and he's just about to hand over the parcel when suddenly this crazy man appears.

You honestly thought you would get away with this?
! Let me explain myself.

Yes, you can explain it to the university! And then what happened?
I don't know.

I wasn't going to stick around to find out, was I?
This crazy man is this him?
Yeah, that's him, all right.

So why did he get himself k*lled?
Well, that's what we're trying to work out.

OK, Marlon, thank you for your help.

What, that's it?
You're not going to charge me?
I got bigger fish to fry.

But consider this your last warning.

You know, I know we haven't always seen eye to eye, but I've always known you to be a decent man.

Thank you for giving me a second chance.

I'm going to use this as a learning opportunity.

OK.

Go on before I change my mind.

Yes, Sergeant.

Sir?
I think we got something.

Roger realised you were looting artefacts and he caught you red-handed.

Well, that's an overreaction on his part.

Yes, I shouldn't have tried to sell the stupid things, but if you knew how much he was paying me Barely enough to survive on, by the way.

Look, I found the coins when we did the initial land survey.

I've got a mate.

He's a bit of a collector.

I saw a chance to dig myself out of a hole, and I admit, not my proudest moment, but I didn't hurt anyone.

That's not how the professor saw it.

He told you he was going to report you to the university Yes.

.

.

which would almost certainly lead to your suspensión and means you wouldn't be able to complete your PhD.

A PhD you'd already spent three years working on.

All that hard work for nothing.

Look, between us, I couldn't give a damn about my PhD.

I've been thinking about quitting for the last year.

Why?
Because I've got other, more interesting worids to conquer.

Listen, I've been doing a bit of thinking about all of this.

It strikes me that the only people that really had it in for the professor were the Joyces.

You mean the mother and son who own this land?
That's right.

The weird son, Julius, I think his name is, he's always lurking about in the bushes trying to psych us out.

Anyone there?
And he got caught smashing up the site the other night.

What the bloody hell do you think you're doing?
! Who are you?
! Roger went nuts at him.

That's why the kid's mum turned up and went nuts at Roger.

Why would this Julius want to damage your dig site?
Because he and his mum have been trying to get rid of us ever since we arrived.

They never wanted us here in the first place.

I was horrified to hear about the professor, of course.

What a terrible thing to happen.

We know you fought to keep them away.

That doesn't mean I wish them harm.

But they overruled you.

We just spoke to the planning department.

We know that they used an Article 37 order to claim that the site's importance meant the dig had to go ahead.

Why were you so keen to stop it from happening?
We lead a very quiet life here.

My son, he's sensitive, anxious, doesn't like to be around people he doesn't know.

Are these sculptures all your own work?
They're a way to keep my mind busy.

They're all made from found materials from my walks.

Something bothering you, Inspector?
Julius! This is DI Parker and DS Cassell.

They just want to ask us a few questions about the poor professor.

We had nothing to do with him.

We know about the argument between your mother and the professor.

After you tried to sabotage the dig site.

They shouldn't have been here in the first place.

So you were hoping to scare them off.

Was that the plan?
Because if you just wanted to avoid them, you could have kept your distance.

He was just keeping an eye on them for me.

Weren't you, Julius?
I just wanted them to leave us alone.

I didn't trust them.

Julius, you've answered the question.

Hasn't he, Inspector?
Thank you both for your time.

You play football?
For St Xavier's?
Used to.

Not so much now.

You should sign up again.

They've been on a losing streak.

Maybe.

You can't even see the dig site from here.

Unless Alice and Julius really went out looking for it, it would hardly have affected their lives at all.

So why were they so protective of this place?
Sir, the team Julius played for, it's my family's church.

The pastor runs a youth outreach scheme.

It helps teenage boys who have troubled home lives.

I could speak with him.

Yeah, it'd be good to get some background, because I can't help thinking there is something not quite right here.

All right, everybody gather their equipment, follow Ed here down the path toward the coast.

So she's moving the dig.

Didn't waste any time, did she?
They've already filled in the old dig site.

The show must go on, eh?
We can't afford to squander all the progress we've made.

But you're not carrying on with the work you were doing.

You are moving the dig to where you always wanted it.

We're doing a few geological surveys, that's all.

Just doing my job.

Now, the term «Arawak» is actually a much broader term used to describe certain groups of indigenous people that existed and, in some cases, still exist Everything all right, JP?
My police badge.

It's gone.

Can't have gone far, surely.

Yeah.

It's got to be here somewhere.

OK, that's really helpful.

OK, thank you.

Bye.

That was Pastor George at St Xavier's.

He remembers Julius Joyce.

He said that Alice enrolled Julius after he'd been suspended from school due to anger issues.

Might explain the trashing of the dig site.

The pastor thought Julius's issues have something to do with his den.

Apparently, he was violent towards both mother and son.

And the den's no longer around?
From our files, it looks like there was a domestic v*olence case gathering against him and then he went off-radar about eight years ago.

Thank you.

It's all over, right?
They're not going to find anything?
It's over.

One of the primary resources of our understanding of these cultures is the i Of course! Why didn't I think of that before?
! Think of what, sir?
The professor's glasses.

Come here.

As he speaks, watch.

He briefly sucks on the arm of his glasses, there, look.

He did it about three minutes ago, as well.

Watch.

There.

It must be a habit of his.

You think the k*ller pasted arsenic onto the end of his glasses?
That is exactly what I think.

There, look, marks where he's chewed them.

That's a sneaky way of getting the victim to ingest a poison.

«Sneaky» is the exact right word, Florence.

OK, JP, could you get these down to the lab and tested for traces of arsenic?
Of course, sir.

Thank you.

Delivery.

Excellent.

Thank you! More eBay purchases?
No, actually, it's my ingredients for the cook-off.

The recipe's about six pages long.

I hope I've got everything.

They're alive! Block all the exits! Get it! Why are they alive?
! You ordered them! I ordered them fresh! I didn't know they'd be walking around! Get them! One suspect in custody, the rest still on the run.

Well, don't wave it around at me! Put it in the box! Might I inquire why there are crabs running around our police station?
They're, my ingredients for the great crab callaloo cook-off, sir.

You're entering the cook-off, a man whose diet predominantly consists of chicken and chips?
Well, I thought it might be fun.

«Fun»?
I can assure you, we islanders take this competition extremely seriously.

I'm really sorry, sir.

I didn't mean any disrespect.

Anyway, I just stopped by to tell you that the PCPRSFYO scheme has been officially approved.

We should have a shortlist of three candidates by the end of tomorrow.

Well, that's excellent news, sir.

Best of luck with your cooking, Inspector.

Thank you.

I might feel better about your chances if you were capable of at least picking up your main ingredient.

Maybe this is a bad idea.

He's hardly going to respect you if you give up now, sir, is he?
Hmmm.

Maybe I could help.

I thought you'd never ask.

Right, so, we've soaked our pig's tail, we've shredded our taro leaves, we've blistered our chillies and we've simmered our crabs.

What else is left?
That's it.

That's it?
Yes, you've done it, sir.

Wow! And it only took us nearly three hours.

What do you think?
I think you should try it yourself.

No, no, it's really not my thing.

This is your callaloo.

It needs to be a reflection of you, your palate, not mine.

You know what?
That's really not half bad.

Wait, there's one more thing we need to add.

No, I don't think so.

Yeah, my mum's secret w*apon.

Are you sure this is a good idea?
Trust me, there's no savoury foodstuff known to man that isn't improved by a few drops of this magical nectar.

Ta-da! Boy! Yeah! That actually looks good, sir.

Uh-huh.

I mean, it's not better than my mother's, but it's a solid effort.

Thanks.

I'm actually really proud of myself, even if I don't have the slightest chance of winning.

Some of these are Look, that's a work of art.

You didn't tell me the Commissioner was in the competition! I am the competition, DI Parker.

You're looking at the reigning champion.

Three years in a row.

Unusual colour.

What does that mean?
Unusual good or unusual bad?
So, it's mainly deep-cover work, sleeper agent kind of thing, you know?
I'm not really meant to talk about it, but, you know, you've got such a trustworthy, beautiful face.

Thank you.

No problem.

So, anything you want?
My police badge.

Just one of my work buddies.

Don't go anywhere.

Don't suppose you believe in third chances.

You got that right.

Ladies and gentlemen, the judges have finally narrowed down their decisión to our two last finalists, our reigning champion, Selwyn Patterson and Spiceman Cecil Cesar.

And the ultimate winner of this year's great crab callaloo cook-off is Cecil Cesar! The judges also decided to give a special award for a unique new twist on callaloo.

Congratulations to Neville Parker! Wow! Thank you! Wow! Thank you very much.

Gosh.

What exactly was your «unique twist», DI Parker?
That'd be telling, wouldn't it, sir?
Worcestershire sauce.

Just a few drops.

Morning, sir.

Just wanted to let you know I'm back at the crime scene.

There's something I want to check out.

I may well have a breakthrough myself, actually, in regards to where the k*ller got their arsenic from.

I'll let you know how I get on.

OK.

It's got to be here somewhere.

Bingo.

Look at this! What a service! A night of free accommodation with breakfast thrown in.

You know, I'm sure the staff could be a bit friendlier, but you can't have everything.

It's not a joke, Marlon.

You're in a lot of trouble, you know that?
So what else is new?
You got any hot sauce for this?
You know, kind of plain, you know?
How many nights have you spent in these cells?
Seven arrests and no convictions! Yeah, that's nothing to be proud of.

I mean, you never, ever think about getting an honest job?
Actually, yes.

You know, I see you and I think that looks like a pretty sweet deal.

And if JP Hooper can do it, then I bet anybody can! Sarge, come on, I'm just having a laugh with you.

Phone your mum.

She won't be up yet.

Plus, she gets really mad when I call her too early.

It's fine, I can make my own way home.

You're not going home, Marlon, you're going to prison.

For what?
For scamming tourists, ten outstanding warrants, theft of police property, impersonating a police officer.

But that was just a bit of fun.

I was only fooling around.

Well, you better hope Judge James gets the joke.

Now, come on, there's no need for any of that.

I tell you what, I'm going to use this as a learning opportunity.

Honore Police.

Yes, sir.

On my way.

So, this is all the Joyces' land, you say, sir?
Yeah, the house is about half a mile to the east in that direction, and the dig site's over there.

And what exactly are we doing here?
Well, this is the site of an old copper mine, JP.

Been gone 30-odd years, I would imagine.

Now, the other day, I noticed Alice Joyce's artwork contained pieces of copper ore that she'd found while she was out walking.

And you think this is where she got it from?
Yes.

But I couldn't work out why it was bothering me until I remembered Otzi the Iceman.

Otzi the who?
The Iceman.

Otzi was a perfectly preserved, mummified corpse dating back to 3300 BCE, found in Austria, and he was discovered holding an axe head made of nearly pure copper.

When they tested Otzi's body, they found he was riddled with arsenic, because copper production and arsenic often go hand in hand.

So this is where our k*ller got the arsenic from?
There's a chance this water is contaminated with traces of it, yeah.

Boil it, you could reduce it down so there's less water and a higher concentration of arsenic.

And then you'd have enough to k*ll.

Exactly.

Yeah, OK.

Thank you.

DS Cassell?
Something you said yesterday, sir, kept playing on my mind, about why the Joyces were so desperate to protect their land.

I spoke with Rebecca and Ed this morning and asked, if Professor Harkness's dig had continued, how far would it have extended?
And it would have come to those trees.

You think there's something here that the dig would have uncovered that the Joyces wouldn't want finding, to the extent that they'd k*ll to keep it buried?
But what?
I searched all over this section of land, from the initial dig area right up to the trees here.

And then I found this.

M-E-G.

Malcolm Errol Gardner.

Alice's partner, Julius's father.

The violent father who disappeared suddenly and hasn't been seen since.

- JP?
Get a dig team on standby.

- Yes, sir.

Julius, we think we know why you and your mother were so reluctant to have anyone digging around your land.

Sorry, I don't know what you're talking about.

Tell me about this.

It's your father's initials, right?
We've read the case reports.

We know what he put you and your mum through.

But the truth is about to come out, Julius.

We'll do everything we can to protect you and your mother, but you have to be honest with us.

I was ten.

My mum did her best to protect me, but that day she was out in town running errands.

He took me hunting in the jungle.

Come on, keep up, boy.

But I was too slow.

I tripped.

I had a swollen ankle.

I could barely walk.

He was angry at me because I'd messed up his day again.

When we got back home, he just took it out on her.

He threatened her with the g*n, like it was her fault.

They started fighting.

Let go! And he was on the floor, just lying there.

Go to your room and stay there.

Julius, go! Next day, she took me to his grave.

I carved this a week or so after.

I felt I had to mark his grave in some way, you know?
I never told Mum, because I just thought she wanted to forget.

There's still one question, Julius.

Who k*lled Professor Harkness?
One of you wanted to prevent him from uncovering your father's m*rder.

My boy's no k*ller! Alice, please, we know what happened to Julius's father.

We know where the body's buried.

It's time to tell the truth.

I'm so, so sorry, Julius.

I didn't k*ll the professor, because him digging up our land?
He was never going to find a body.

Julius's father isn't buried under that tree because he isn't dead.

I didn't k*ll him.

I saw it.

I saw him.

The blood He was injured, that's all.

The b*llet hit his arm.

A lot of blood, but no real harm.

So I bandaged him up and I told him I'd give him my life savings if he left the island, but if he stayed, I'd k*ll him, I'd sh**t him and make sure I didn't miss.

I didn't ever mean to hurt you.

I just wanted you to stop having the nightmares, enjoy your childhood, not be haunted by the thought of him coming back and hurting us both again.

If you thought he was dead, then you'd have peace.

I'm sorry! Please Yes.

Sir?
So, the dig team went down pretty deep, and there's no sign of any body.

It's not unexpected news.

We contacted the authorities in the Cayman Islands, and reports confirm that Malcolm Errol Gardner is currently living in George Town, all of which kind of puts us back to square one.

Who poisoned Professor Roger Harkness and why?
Actually, sir, I'm afraid we may be even further back than square one.

No! That was the lab.

They've tested the professor's glasses for arsenic - and - Don't say it.

not a single trace.

But that's the only way the victim could have ingested the poison! None of these other items are edible or suckable or chewable.

So how the hell did the k*ller, whoever he or she may be, manage to get arsenic into the professor's system?
! Unless you're right about him losing a bet and eating his own hat.

There might be something in that, actually.

I think JP was joking, sir.

No, I'm not interested in the hat but the pakamac.

Or, rather, both pakamacs.

It seems like Professor Harkness liked to be prepared for all eventualities.

It all comes down to the kind of person that Professor Roger Harkness was.

And if you knew that, you'd know exactly how to k*ll him.

This is Professor Harkness.

Look, marks where he's chewed them.

That's a sneaky way of getting the victim to ingest a poison.

They're all made from found materials, from my walks.

Julius! Didn't waste any time, did she?
They've already filled in the old dig site.

So either she's the k*ller and this is all just some kind of double bluff Why would I want to k*ll a man over a career I didn't even want?
You've been poisoning his daily coffee because he wouldn't let you have your own way.

And that's how they did it! You know what happened?
Yes, I do.

And I tell you something, Florence, it's more than sneaky, it's it's REALLY sneaky.

I'm still not quite sure of the why yet, but I have a feeling a quick phone call will help us with that.

And, JP, I'm going to need a metal detector.

OK.

It feels so good to be dirt-fishing again after all these years.

«Dirt-fishing»?
I'd forgotten how much I enjoyed this.

Come on, this is the obvious place.

I've found it.

What is it, sir?
It's a glasses case with glasses.

How the hell did he know there would be a glasses case buried there?
We found it.

We bloody found it! Alva was right all along! Whoohoo! So you found the temple?
Yeah.

Coincidentally, we've made a couple of discoveries of our own.

Ed?
JP, if you wouldn't mind?
I think we got him, sir.

As you can see, we've identified the k*ller.

But since you were all involved in this horrible incident, we thought you deserved an explanation.

Do you really think I'd k*ll a man over a few gold coins?
We don't, actually, not even for a moment, because that's not the real reason you k*lled Professor Harkness, is it, Sr.

Lancer?
When Roger found out about your little scam, we know that he threatened to report it to the university.

You honestly thought you'd get away with this?
! Let me explain myself Yes, you can explain it to the university! But as you made perfectly clear to us, you couldn't care less about your PhD.

I've been thinking about quitting for the last year.

Why?
Because I've got other, more interesting worids to conquer.

And by «interesting», you mean lucrative.

We noticed you have an agent.

He has over 50.

000 followers.

And, apparently, a showbiz agent.

So we gave him a call and asked if he knew what these «other worids» might be.

And he forwarded me this.

Your contract for presenting a new TV show, Unearthed Britain.

A six-figure salary for your first ever TV gig?
It's not too bad, I should say.

I'd no idea.

I doubt Roger did, either.

He thought you just stood to lose your doctorate.

Look, I couldn't have k*lled him.

Yeah?
When Roger was poisoned, I was with Rebecca.

You can vouch for that.

We're well aware of that.

But you were also living cheek by jowl.

You've no idea how hard it's been, living on top of each other.

So, presumably, you'd observed what Rebecca was up to with her little bottle of poison.

All you had to do was piggyback on her plan.

First, you had to work out how to get your hands on some arsenic.

I presume you're aware of Otzi the Iceman.

Of course, with the copper axe.

Well, just like poor Otzi, the water around the old copper mine about half a mile away is riddled with arsenic.

You would have known this, as Professor Harkness asked you to survey the site a few days before.

I've had to redo the entire grid because Ed's measurements are out.

How he ever got accepted for a PhD is beyond me.

The professor had no idea that, instead of doing your job, you were collecting the means to k*ll him.

So you had your poison, then you had to work out how to administer it.

Well, after a month, you were all too aware of each other's quirks and routines.

We all have our little habits.

And while I watched an online lecture of the professor's, I noticed one of his.

As he speaks, watch, he briefly sucks on the arm of his glasses, there.

A tendency to absentmindedly suck or chew the arm of his glasses.

You must have noticed it, too, and it suited your purpose perfectly.

All you had to do was place the poison on his glasses and wait.

It's a very sneaky way to commit m*rder.

But you were even sneakier, because when we tested these glasses for arsenic, we couldn't find a single trace.

Because the glasses we sent to the lab weren't the ones Roger was wearing when he d*ed.

See, Roger was a man who liked to be prepared for every eventuality.

In his rucksack, he had a spare of everything.

Ruler.

Second ruler.

A pakamac.

And another pakamac.

So it stands to reason he would have carried a spare pair of glasses with him at all times.

But we only found one pair.

That's because, as soon as Roger was dead Call an ambulance.

you switched his two pairs of glasses and then later disposed of the ones with arsenic on when you filled in this old dig site.

With the evidence gone, you just had to sit and wait it out, banking on the fact that we'd arrive, test the coffee and immediately conclude that Rebecca was the k*ller.

But what you didn't realise was that Rebecca's attempts to forage arsenic were a great deal less successful than yours, leaving you exposed as the real poisoner.

Edward Lancer, I'm arresting you for the m*rder of Roger Harkness.

If you want to leave, I understand.

Sir, I'm afraid I need to get that back to the shop now.

Actually, I popped in on the way back and I I bought it.

Is that a good idea, sir?
I mean, it's not exactly embracing island living, is it?
I disagree.

What better way to get in touch with the soul of the island than to go searching for traces of its history?
Hm?
Don't you think?
I'm pleased to tell you of all the candidates put forward for the youth scheme, one stood head and shoulders above the others.

I wondered what the Y stood for.

Youth.

Yes.

He's a little rough around the edges but full of raw promise.

And what about the O, sir?
What does that stand for?
Offender.

As in «criminal»?
As in «youngsters who've taken a wrong turn».

I, for one, do not want to live in a worid where no-one is allowed a second chance.

Now, if you'll all accompany me, I'll introduce you.

This is Trainee Officer Marlon Pryce.

He assures me he's ready to turn his back on his former life and use this as a learning opportunity.

Thank you, Commissioner.

You're not going to regret this.

Welcome to the team, Marlon.

Sergeant Hooper here will be in charge of your training.

I believe you two are already acquainted.

Yes.

We're old friends.

Aren't we partner?
Trainee Officer Marlon Pryce Tell you what, Sarge, we're going to make a wicked team.

You and me are going to be like Bad Boys.

You seen the movies?
No.

Don't worry, I can get you the DVDs, you know?
And look out, look! That's my girl from the other night.

I can tell her that I'm the real deal.

If you're getting the drinks in, I'll have a rum.

Large.

Is he the new recruit?
Yup.

His name's Marlon.

He seems lively.

The boy has no manners, no discipline and no self-control.

I mean, how am I supposed to work with someone like that?
Sounds like the perfect training for fatherhood.

Well, he is trying, sir.

He certainly is.

What kind of philistine adds Worcestershire sauce to callaloo?
I don't believe it! Look! I've only been going half an hour and look what I've found.

I mean, it could be an ancient arrowhead.

Maybe Arawak?
If you look at it, I think you can see the tool work.

This is a piece of propeller blade from an outboard motor, maybe late 20th century.

I think your skills are better suited to the day job.

Was that a compliment, sir?
Let's not get ahead of ourselves.

So, you never finished telling me the story about why you hate shellfish so much.

You were on a date?
No?
Do I have to?
It's really embarrassing.

Well, if I have to help you detect metal, then I want to hear the story.

OK.

So, I was trying to impress my date, Zoe, so we ordered lobster, and I got a bit carried away with the whole shell-cracking thing and, well, a bit of shell flew off and hit her in the eye and scratched it quite badly.

Very badly, actually.

She had to be taken to A&E.

The worst thing was, she had to wear an eye patch for three weeks after.

She was a bridesmaid at her sister's wedding.

Poor girl! Yeah.

Well, I take it you didn't see her again.

Actually, we were together for four years after that.

That, DS Cassell, is a story for another time.

OK, if this is treasure, we split it 50-50.

Deal?
Deal.

Here it is, home sweet home.

Not too shabby, I suppose.

They got a bob or two, these Jacksons?
Eight million, to be precise, sir.

They won the lottery back in the UK.

Marlon, your first lead.

Well done.

Thanks.

Some things that you need to know about Cherry and Gavin.

Where is he?
! Dan?
Just get out of there now.

God! Danielle?
I need to see JP! Get him here now! You look like you're getting worked up, like somebody's annoyed you.

You need to get yourself over to the hospital now.

It's baby time.

There's been a minor delay, but I'll be there as soon as I can, OK?
Does this thing go any faster?
