[Phone rings]

If the good lord had intended man to dive underwater

he'd have put lead weights in his head.

Nightmare.

Jane needs a load of dosh for a new roof.

And now Alison tells me she needs her patio relaid.

Ooh, this is interesting.

When I was a staff officer at the yard,

police divers were part of my remit, they were damn fine.

I just wondered if you could help me financially.

Actually, Jack, I qualified as a diver

when I was on holiday.

Oh, takes all sorts.

I never knew you were a diver, Sandra.

How long'd that take you to learn?

Not very long, just a few days to learn the basics.

Remember hans and lotte hass on telly when we were kids?

[Gerry] Oh-ho, not many.

[Brian] I never missed that programme.

No, nor me.

What, you were hooked on diving?

No, no. No, it wasn't that.

No it was, well, this was the 50s, you see?

It was the only show on TV

where you could see a fit bird in a swimsuit.

How old were you Gerry?

Well, dunno, er, nine, 10, I suppose.

Yeah, I've always had a thing for older women.

Now there aren't any.

[Brian and Jack laugh]

This is fresh evidence in the case of Marie sinclair,

shot dead.

Sinclair, sinclair.

Yes, 1989.

[Sandra] That's the one.

Married woman,

was having an affair with her husband's employee.

Yeah, and his name was Michael Dudley.

He disappeared, along with the security Van he was driving,

around the time of the murder.

And the husband was in the frame for it, right?

Andrew sinclair.

Dudley's disappearance has never been solved.

The investigating officers at the time believed

that sinclair killed his wife and the lover.

The crown prosecution service

felt there wasn't enough evidence to proceed.

[Brian] That one.

Right now, this place is called winfield lake,

it's a disused quarry that was flooded 30-odd years ago.

Now being turned into a commercial water sports centre.

Are these our guys?

No, no, no, they're doing an underwater survey,

first time it's been done.

Here we go.

Hang on a second,

- what is... - It's an old armadillo.

Oh is, you know.

I take it this is the Van that Dudley was driving?

Yeah.

[Jack] Any sign of the missing man?

No, the divers didn't attempt a search,

they just reported it and then sealed off the site.

Yeah, but it could be a knockoff.

What was it carrying?

Bullion? Cash?

No, no, no, no, it was just a straightforward courier run.

The driver was delivering and picking up packages,

nothing of high value insurance.

So, I'm tasking you

with re-investigating the sinclair murder

and Dudley's disappearance.

So this time you want sinclair done and dusted.

No, I want closure, Gerry,

and I think ucos can deliver.

Bollocks.

Would you care to expand on that, Mr. Sinclair?

You're not going to reinvestigate my wife's death,

you're here to have another go at pasting me up for it,

aren't you?

[Sandra] New evidence has turned up

relating to Michael Dudley's disappearance.

Well?

The armoured vehicle he was driving has been discovered

at the bottom of a flooded quarry, winfield lake.

Given what's been found, and where that might lead,

is there anything you'd like to say now

that might help us to clear the matter up?

I've always told the truth.

Well, let's get back to basics, shall we?

Where were you on the morning of September the 16th 1989?

I was on the road, I done a visit to a potential customer

who wanted a quote for a regular payroll delivery.

We've got, you down as security company proprietor,

did that include sales?

Yeah.

We were a tuppence-ha'penny security firm,

I did a bit of everything.

We got taken over shortly after.

Your wife was shot dead that morning.

According to the original investigation,

you would have had time to go home after that meeting,

then get back to the office where you were arrested.

Yeah, but I didn't.

What was your relationship with Michael Dudley?

He was one of the drivers.

We were mates, really.

Did you know Dudley was having an affair with your wife?

I've been through all this.

Yes, well, we're going to go through it all again.

[Suspenseful music]

- [Water splashes] - [Gravel crunches]

If sinclair killed his wife at their home,

he couldn't have dumped the Van here

and then got back to his office.

Why not?

Because it's too far, he wouldn't have had time, surely.

No, it's easy peasy.

I mean, he wouldn't have messed around on the a and b roads,

would he?

He'd have done a dogleg on the motorway.

[Brian] That's even further.

No, but it's much, much quicker.

That's what motorways are for, Brian.

You're thinking like a cyclist.

[Engine knocks]

You had this converted to diesel?

No. Just needs a bit of attention, that's all.

Mr. Wilmslow?

Gerry standing, Brian Lane.

Nice to meet you.

[Brian] 'Ow do?

So you're the owner of the site, right?

My company acquired it for development earlier this year.

How secure is it?

- It's a big site. - [Bird warbles]

A crested grebe.

A what?

[Bird warbles]

Isn't it wonderful

how nature reclaims a blighted industrial landscape?

We'll soon deal with nature.

Marie worked part time with me on the administration side.

Mick Dudley, he was an interesting bloke.

A good laugh.

The three of us got into the habit of drinking together,

going out for a meal.

Sounds cosy.

Friends, that's all.

Well,

that's what I thought.

It wasn't that way for Marie.

And how did you find that out?

Marie told me

that she and Mick were attracted to each other.

We didn't have any secrets.

And what about your feelings?

I wanted to know what that meant for us.

I didn't want to lose her.

[Sandra] What did she say?

She said she loved me,

there was no question of her leaving me for him,

it was just a physical thing.

And your reaction?

Marie knew her own mind.

If that's what she wanted, if he didn't threaten us,

I wasn't going to stand in her way.

We had an open relationship.

You saying you never even got angry?

Maybe angry inside myself, but never violent.

Not with Marie.

I loved her.

I still do.

[Gerry] So anyone could get access to the site?

Yes.

They've been using it for years, nobody tried to stop them.

Who are they?

Divers, mostly.

It's well known as what they call an unregulated site,

that's how we know it'll work as a commercial venture.

So what's the layout underwater here?

Well, what you've got is a broad shelf

at about nine, 10 metres over on the far side.

That's where the novice divers

would do what's called their open water training.

[Paul] Yeah.

Then there's a drop off down to 25, 30 metres.

And just here, it goes down to 40 metres or more.

And that's where the Van was found?

Mm. That set us back in development terms,

every minute your inquiry costs me money.

So, you had a civilised discussion with Marie,

what about Mick Dudley?

We had to work together.

You don't start that sort of discussion

during the tea break, do you?

Do you mean to tell me you were working normally

with a friend who was sleeping with your wife?

Maybe that makes me look like

some sort of creep in your eyes,

it doesn't make me a criminal.

How long did this go on?

Only a few days, and then

Marie was killed and Mick went missing.

So a few days after you learned

that your wife is having an affair,

she is murdered and her lover disappears.

I know how it looks.

I've had all this aggravation before

because of how it looks.

And you still maintain that Dudley killed Marie?

It's bloody obvious.

Marie must have tell Mick what the score was,

it was just a fling, they had no future.

Mick killed Marie and, well,

he did a runner and left me to take the blame.

Extensive efforts were made to find him at the time,

both here and overseas, and yet he was never sighted again.

Very wise of him.

The more obvious explanation is that you shot Marie,

killed Dudley and disposed of his body.

Oh yeah?

So where's the evidence?

Where's Dudley's body?

Where's the gun?

[Phone rings]

Sandra Pullman.

Oh, hi, thanks for getting back to me.

So what can you do for us?

You cannot be serious.

This is a murder inquiry, of course it's urgent.

Well, the actual crime took place in 1989.

Well, if that's the best you can do for me,

I'll have to live with it, won't I?

Cheers.

Underwater search unit?

They're involved in two current investigations

and won't be able to mount

a full-scale search and recovery operation for us

for at least a week.

[Brian] Look, Gerry, this is what happens

when you use your enhancement tool.

Good pictures aren't they? Yeah.

[Brian] Here it comes, here it comes.

What are you doing?

This is fascinating.

Now, look.

You zoom in,

and you can see the rear door lock.

It's been blown open.

So that means that someone blew the lock

and then dumped the Van in the lake.

Well, that would be the lay person's view, naturally.

We've been talking to an explosives expert.

And?

Well,

the propagation of a pressure wave,

a sound or shockwave from an explosive blast,

is different in air from water.

What he's trying to say is,

the explosion took place under water.

[Brian] That is interesting.

[Sandra] It sure is.

Yeah, the Van went into the lake intact,

then a diver went down and blew it open.

I wanna know what was on board that Van.

[Engine rumbles]

'Course, this is all before my time.

My group didn't get involved in the security business

until the early 90s.

Yeah, sinclair's firm was our first acquisition.

You've acquired a few since then.

Well, that's how I do business.

So what did you do before then?

Medical equipment and supplies, export mostly,

the middle east.

Would you still have the records for sinclair's firm?

Ooh, now you're asking.

Well, we've, er,

we've got some archives down in the basement,

but god knows what's there.

[Upbeat music]

This way.

Straight on.

You know, we've got lots of, uh,

ex-policeman working with us.

[Brian] Oh yeah, you would.

Yeah. A good ex-copper's worth his weight in gold.

Huh, I wish I was.

Oh yeah, I had an estimate for the car,

new short engine, 1,500 quid.

Oh, you're on your own with this lot.

See, what we need is a, what would you call it?

Manifest bill of lading.

Something to show just what was on board the Van.

Oh, there wouldn't be a document like that.

How come?

Well, think about it as a post office Van.

There's lots of parcels from everywhere.

I mean the contents could be anything.

Yeah, but see, each package would be numbered,

so somewhere there'd be a record of who sent each package.

The consignors, yes.

So in principle, you could trace the consignors

whose stuff was on a particular Van?

And they would tell you what it was.

Well, theoretically that's possible, yes.

If they still existed, or if they kept records.

But it'd mean matching piles of documents.

Let's get matching.

1990,

aha, 1989.

Oh, look at that.

Yes, yes.

Well I don't envy you your job.

Has its moments.

Just before you get stuck in, can I have a word?

Yeah, what?

This parcel came today.

Oh yeah?

I thought it was my new curtains,

so I started to open it,

and then I realised that it is addressed to you.

That's all right, I have no secrets, Esther.

Well, I was beginning to wonder.

It appears to be rubber garments.

Fantastic.

Did you send for this?

Confession, I panicked a bit about your size,

so I opted for petite, yeah.

Oh, you got something for me?

Yeah, his'n'hers. [Chuckles]

And look, they come with matching booties and hoods.

Oh,

smell that.

Oh, where did you get this notion from?

Oh, I fancied doing this for years.

Plus we were watching this video at work-

video? I think I need a drink.

And there'll be none of that when we take the plunge,

drinking and diving don't mix.

What?

Drinking and scuba diving.

You want me to go diving with you?

Of course diving.

What else would I want with wet suits?

I want us to be buddies, Esther,

exploring the silent world,

learning the secrets of the deep.

Absolutely not, never.

Why not?

I have only ever seen you flopping about on a lilo.

How well can you actually swim?

Like a dolphin.

Oh please. [Laughs]

Oh, dear.

[Sandra] Right, let's look at where we've got to.

[Jack] Sinclair still denies, killing his wife

and he didn't strike me

as an ideal candidate for a crime of passion.

[Garry] Why not?

'Cause there's not much there in the way of passion,

he's creepy.

[Jack] And the fact that the Van was broken into

suggests there's more to it than just a love triangle.

So, Michael Dudley's disappearance.

Well, we can't trace any of Dudley's movements

after he picked up a consignment in his Van

near sinclair's house.

Now, he could have gone to sinclair's house,

and become victim number two.

Or killed Marie and done a bunk.

Amazing how popular scuba diving is.

Brian, can we concentrate on the case?

All sorts of people qualified as divers,

prince Charles, fidel Castro.

Thank you, Brian.

Michael Dudley.

Eh?

I've just checked Dudley's name,

along with Marie and Andrew sinclair

on the UK divers register.

Michael Dudley qualified as a divemaster

when he was in Australia.

Bloody hell.

So if it was Dudley who killed Marie

and organised his own disappearance.

And then dumped the Van in the lake.

Then, as an experienced diver,

came back later to retrieve something.

And hence the door blown open.

Do you think Dudley could have known about the lake

through diving with one of the clubs that train there?

Well, we're never going to find out, are we?

They were all trespassing.

[Steve] Well, thanks for coming in Gerry.

I take it this isn't police business.

No, no.

In fact, I need some help myself right now.

And I got the sense that you were a bit pressed.

Financially.

Not half.

Well uh, I need somebody to cover my late shift

in the control room.

Nothing happens at that time of night.

Put your feet up, read a book.

And, uh,

cash in hand, if that suits.

[Upbeat music]

When can I start?

Scotch?

Yeah, why not

[Man on radio] Panther 19 to panther control.

Do what?

[Man on radio] Panther 19 to panther control, receiving.

Yeah. I'm sorry about that.

Panther 19 receiving.

[Man on radio] Yeah, soon be leaving Heathrow.

19, leaving Heathrow, understood.

[Keyboard clatters]

How's it going?

Blimey, you work late.

Well, penalty of being the guv'nor.

You got the hang of it?

Well it's hardly rocket science, is it?

There's only a couple of vans active.

It's important to have a reliable man in charge.

Gerry.

Ah, yeah.

Thanks Steve.

Am I right in thinking that the tax man

doesn't need to know about this?

I learnt my business skills in the middle east. [Laughs]

Rest easy.

Cheers.

[Upbeat music]

[Door clicks]

Good boy.

Rutabaga.

I mean, you've got a kid at university

up to her ears in student loans and she needs a new laptop.

Well, you can't say no, can you?

Five letters.

But where's it come from, eh?

My motor needs fixing, the bank are on my back.

Morning Brian.

Morning all. Beautiful morning.

[Desk thuds]

Who put that there?

Rutabaga, five letters.

I mean, how can they ask you

to choose between your motor and your own flesh and blood?

Rutabaga?

Rutter what?

It's a crossword.

God, where were you last night?

You look like death.

Morning, Jack.

Actually I'm having trouble sleeping.

It's financial stress.

Hey, hey, hey, hey, cracked it.

What?

I know what dive clubs use winfield lake.

Seriously?

Deep on the web, in the blogosphere,

information sleeps like a beautiful Princess,

only awaiting a kiss

from a subtle and sophisticated search algorithm.

Just tell us what you've found.

Certainly, deepdeepdive. Com newsletter

carried out a survey of accidents

in inland dive sites over the last 15 years.

Winfield lake only featured once.

Decompression sickness.

That's bends, Gerry.

Here we go.

Winfield lake, accident, December 1995.

An emergency call was made

reporting a diver with severe pains in the joints

and some sensory neural dysfunction.

The symptoms were present shortly after the diver surfaced.

First aid was administered at the time

by the diver's companion a miss Trisha king.

An air ambulance was called

to carry the diver to the nearest re-compression chamber.

What was the outcome?

The patient made a full recovery.

Well, good luck to him, but where does that get us?

Most clubs using winfield only used it

for training at the 10 metre level.

Some clubs went down to the shelf at 30 metres.

This diver, who required emergency assistance,

went down to 45.

Where the Van was found.

The diver's name is Martin viner,

the club is osprey subaqua.

Rutabaga is a turnip or a Swede.

Oh yeah, thanks.

Hold on, have a listen.

What about this?

Martin viner turns out to be

Michael Dudley.

Well, what's the betting?

50 quid says he isn't.

You're on.

[Sandra] Martin viner?

Uh, yeah, but actually I'm really busy here.

Cash only, please.

Detective superintendent Pullman,

I'm afraid this is official,

we need to talk to you about winfield lake.

Oh, right,

well if just give me a minute to get finished up,

I'll talk to you upstairs in the clubhouse.

Fair enough.

It's this way.

Yeah, come on through.

Quite a setup you've got here.

Well the members enjoy it, and it seems to work well.

What exactly are your positions in the club?

Well, we're both qualified instructors.

I'm the company secretary, and Martin is the diving officer.

We'll need to talk to you separately.

Yeah, sure. Let's get it on.

I can't see why this is a police matter.

I mean, diving in winfield lake might be trespassing,

but no one's ever really seemed that bothered about it.

We're not here to talk about trespassing.

We're re-investigating a disappearance.

And a murder.

No, I don't know any of these people.

Not this one?

Michael Dudley.

So, he was never a member of this club?

Not to my knowledge, no.

We're going to have to check all the membership records.

Sure. But like I said, I've never seen him before.

Sorry, no, I don't know these guys.

I've never dived with any of them.

- No? - No.

Okay. Let's move on.

How many times have you dived winfield lake?

Well, I'd have to check the records,

but I'd say we used to go, what? Four or five times a year.

That was before the new owners got heavy.

It's a great place for a bit of open water training.

You're saying you've never been any deeper than that?

Oh, what me personally?

Oh yeah, yeah, yeah, I did actually, just the once.

Me and Trisha, you know, it wasn't a training session,

we just wanted to see how deep it was.

I got the bends, didn't I? Silly me.

So, what did you see down there?

Well, at a high level, you know,

there was dace, perch, crayfish.

At the bottom there was this big old pike.

How about an armoured security Van?

No.

This was taken at the bottom of winfield lake.

Well, I'll be buggered.

Look at that.

Well, you never know, do you?

You didn't know it was there?

No.

Well, i'd've been really interested.

[Brian] You record all your dives in a log book?

Yeah, since I qualified, 1994.

Yeah, we're going to have to check those as well.

Sure.

But you won't find any mention of armoured vans.

And all your log book entries are fully accurate are they?

Yeah, of course.

I find it very hard to believe that you didn't see that.

Well, it's a large body of water.

The viz is none too clever.

- The what? - Visibility.

You could lose a double Decker bus down there.

[Jack] Come on.

What's your experience of British inland dive sites?

Actually, I've done all of my diving in the tropics.

We're not talking

warm-water girls'-choir stuff here, Sandra.

It's very different.

[Brian] What's this one?

Spanish dancer, Egypt.

And here.

That's a cleaner shrimp, I took that in Australia.

[Brian] You certainly get around.

Makes you wonder

why the bottom of winfield lake's so attractive, doesn't it?

But anyway, I'm going to find out.

- What, diving? - Mm-hmm.

Yeah, we're laying on a little expedition

for the superintendent, check out her diving skills.

Fantastic.

Excuse me.

Are you out of your tiny mind?

I made a command decision, end of story.

You're a real lifesaver

pleased to help.

Oh, by the way,

is your firm making any progress

with all that bumf from the archives?

Don't ask me, I'm only the monkey.

The organ grinder is going scuba diving.

Really?

What's that in aid of?

We found this diving club

that might have had access to the Van.

Is that right?

Yeah.

So the guv'nor is going to have a look,

see what's down there.

Well, good on her. [Chuckles]

This is seriously out of order.

They are well dodgy,

and she's putting herself on offer

underwater with one of them.

It's a lake, not the Bermuda triangle.

He has to come to the surface again.

God you look knackered, what have you been up to?

[Grunts] And he's a wrong'UN if ever I've seen one.

What's he doing now?

[Brian] They're checking each other's equipment.

Thanks.

Yeah, right.

I mean, she'd stamp at me doing that, wouldn't she.

She's not going down with you.

[Martin] All set?

[Sandra] Sure, yeah

now just remember, Sandra,

it's not the gin-clear water of the tropics.

[Outboard motor whines]

[Upbeat music]

[Water splashes]

[Ethereal music]

The conquest of inner space,

I wish it was me.

I wish it was you too.

[Air bubbles ripple]

Easy to forget

what a hostile environment it is down there.

Decompression sickness apart, there's hypothermia,

nitrogen narcosis,

burst lung.

Oh, knock it off will you?

[Paul] Morning.

- All right? - Mr. Wilmslow.

Any idea how long this is going on for?

As long as it takes, basically.

[Tense music]

Shouldn't they be up by now?

[Suspenseful music]

[Dramatic music]

And you're confident of that result?

Magic, cheers. Bye

Ballistics have just confirmed

that that gun fired the fatal shot.

Can we tie it to sinclair?

We'll have another go at him. Ready, Jack?

You bet.

[Upbeat music]

[Gerry] So, what you doing?

Oh, blimey.

You're not still fretting

about the time it took sinclair are you?

September 16th 1989.

Articulated lorry jackknifes on motorway,

causing massive tailback.

He'd have had to use the a and b roads.

Well, you put your foot down,

it can still be done in time, trust me,

[Jack] That gun was found in Michael Dudley's Van

at the bottom of winfield lake.

[Sandra] It fired the shot that killed your wife.

Yes.

The forensic science laboratory is examining it right now.

It's amazing what they can find these days, Andrew.

Not just fingerprints, human hair, sweat, traces of tissue

can all provide identifiable fragments of DNA.

Now, if there's anything you can tell us

about this weapon,

then the sooner you get it off your chest,

the better it'll be for you.

Yeah,

okay.

It's my gun.

[Engine revs]

Has the engine stalled?

No.

It's not making the rattling, grinding, banging noise.

No 'cause it's had a small fortune spent on it.

Thought you said you were hard up.

Had a bit of luck. Now get on with it.

Certainly.

This is where Andrew sinclair met his customer.

So, he'd have had to go on home from here,

kill his wife, and presumably her lover,

then make his way all the way to winfield lake,

dump the Van, and the gun,

then get all the way back to his office

before the police came for him.

Piece of piss.

So, show me.

[Engine revs]

I wanted the gun for a bit of personal protection.

I bought it off a bloke in a pub for a monkey, no history.

Bloody stupid as it turned out, but there you are.

You killed your wife, you killed Dudley,

and then you dumped the gun and the Van in the lake,

isn't that right?

No.

[Engine rumbles]

[Tyres squeal]

Right, this is the scene of the murder

and we're already running late.

Yeah, but there wasn't so much traffic in '89 was there?

Sinclair's gotta kill Marie, and kill Dudley,

or take him prisoner,

so we'll add on 10 minutes.

No, five.

Split the difference, seven-and-a-half.

All right.

Go.

[Engine revs]

Where's Dudley's body, Andrew?

I didn't kill Dudley, I didn't kill Marie.

Michael Dudley had the gun, I lent it to him.

What for?

You know what young men and guns are like.

He fancied playing at Clint Eastwood,

blowing away a few tin cans.

Why didn't you tell us this before?

I didn't think it would be credible.

It's not, tell the truth.

- [Engine revs] - [Gravel crunches]

Yeah, right.

So, now sinclair's gotta dump the Van in the lake.

Two minutes, top whack.

All right, I'll indulge you on that one, Gerry.

But answer me this.

If sinclair drove the Van here and dumped it,

then how'd he get back to his office?

He'd already left a vehicle here.

No, no, no, here's a good one,

he put a motorbike in the back of the Van

and got away on that.

Ooh, you're clutching at straws, Gerry.

Anyway, you might as well admit defeat,

we've only got 20 minutes left.

All right, I'll put my foot down.

- [Engine revs] - [Gravel crunches]

- Why won't he just roll over? - [Phone rings]

Maybe he's telling the truth, or some of it.

Sandra Pullman.

Traffic division?

[Upbeat music]

Yes, he is known to me.

[Traffic officer] He claims he was on police business,

your unit.

[Cheery music]

Yes, ma'am.

[Gerry] Well?

Detective superintendent Pullman says, "bollocks."

[Gerry sighs]

Unorthodox conduct from the civilians in the team,

but you're a police officer Sandra,

and you're not qualified to dive in the course of your work.

There are profound health and safety implications.

We found new evidence, sir.

-Well- -the fact is, sir,

that this inquiry demanded resources

that were not made available to us,

like the underwater search unit.

And surely the responsibility for this

must lie at a higher level of command.

Yes, yes.

But surely the real question is what is the way forward?

Well, Brian and Gerry have already shown

that sinclair couldn't possibly

have dumped the gun and the Van in the time available.

If he did kill his wife,

then he was working with someone else.

This isn't a straightforward crime of passion,

there was something else going on,

and we think it's to do with the contents of the Van.

Brian.

Yes, Gerry and I have worked through the documentation.

We've traced all the consignors

whose packages should have been on board,

except for one outfit, gryphon mount technical services.

Which doesn't exist.

And according to company registries,

phone books and business directories, didn't even then.

It's got all the signs of a front

for something very dodgy,

drugs maybe.

Now they were still doing business with sinclair

up to '89, but then it stopped dead

as soon as Dudley and the Van disappeared.

So we need to know if the gryphon mount packages

are still on board that Van.

Because if not, if they were being ripped off,

this could be the key to the whole case.

Well, the underwater search unit

still say they can't prioritise this case.

Fine, then I'll do another dive

and try and establish an inventory.

Sandra, for god's sake.

Well, clearly this is a matter of debate within the team,

so nobody can regard it as a decision I've sanctioned.

[Gentle music]

Gerry.

[Gerry] Uh-oh.

Jack, do me a favour, will you?

What?

Go back with Gerry and have another look

at the archives at Palmer's place.

Why don't you go?

Oh no, I can't, I'm going diving.

Well, I'm part of the backup team.

And your problem is?

It's not my problem, it's your problem.

Look, you don't need to do this diving lark,

we got professionals for that sort of thing.

Not currently available.

But you're the guv'nor,

you shouldn't be sticking your neck out,

you've got responsibilities.

My responsibility is to see that the job is done.

Yeah, but that's not why you're doing it, is it?

You want to prove something, don't you?

That you're top girl, the best, the fastest, the bravest.

Balls.

The very word.

And you want some.

No, no, no.

What's pissing you off

is the fact that a girlie is doing things you can't do.

It's called old-fashioned male chauvinism.

Yeah, well maybe so.

But whatever you want to call it,

what's pissing me off is the fact that I have to hang around

like a spare part when you might be in danger.

Gerry that's really-

and if you say, "that's sweet of you,"

I'll punch your lights out.

You and who's army?

[Gerry laughs]

Look, it's not just me-

I hate saying this,

but it really matters to me

that I've got you and the other two dinosaurs

watching my back, it means a lot.

Yeah, well.

Good.

[Scoffs] Don't take the piss.

[Tense music]

[Air regulator hisses]

[Paul] Be nice to get all this sorted.

[Brian] Certainly will.

I've got plant and equipment waiting to move in.

[Water splashes]

Hello Gerry, you on for tonight?

Ah, Steve, um, yeah

I'd like you to meet a colleague of mine,

Jack halford, Steve Palmer, the big boss here.

Glad to meet you Jack.

I thought you'd got everything you wanted.

Well, yeah, but we reckon we know

what packages were aboard that Van.

So the inquiry's taken a bit of a new turn.

Oh, well, if you can let me know what you're looking for

I'll point you in the right direction.

Well, actually, what we are looking for-

it's all right, Mr. Palmer,

I think we can manage on our own, thank you,

just have a look around, see what we can find.

Right?

Well, I'll leave you to it.

Yeah, cheers.

What was all that about?

There's an inquiry in progress,

I don't think we should tell members of the public

any more than they need to know.

We're on the same side.

You and Palmer?

Gerry, what's going on here?

What was all that about, "are you on for tonight?"

Look, I do a bit of work for Palmer, that's all.

In my own time, of course.

You what?

I'm not a copper anymore, the same rules don't apply.

How much money we talking about?

Ah, wages that's all.

And how you paid for the car?

Exactly.

You're taking a hell of a risk.

Don't worry, Steve's all right, he's straight.

Is that a fact?

Yeah.

Ah, look at this.

Duty rotas.

And these two boxes cover the entire period.

Right, come on.

Let's get outta here.

[Tense music]

[Water bubbles]

[Intense music]

[Trisha] The north side of winfield lake, it's 14 metres.

I'm administering cpr, he's not responding.

Do you hear me?

You've got to get here immediately.

Come on! Come on!

Come on!

Come on!

[Water splashes]

What happened?

[Sandra] He had some kind of seizure.

[Trisha] Come on.

There's another body at the bottom of the lake.

Oh, terrific.

That really puts the tin hat on it.

[Trisha] No. [Sobs]

[Sandra] Martin viner was murdered,

his number two tank was filled with pure oxygen.

[Gerry] That's what we all breathe isn't it?

No, Gerry, we breathe air, which is 70% nitrogen.

Breathe pure oxygen at more than 12 metres or so underwater

and it becomes a poison.

I told you, sheer bloody madness.

All right, Gerry, point taken.

Who filled the tanks?

The club's got its own compressor,

but the murder squad have sealed it off as a crime scene.

They're willing to pool information with us, though.

What about the other body?

The documentation on the body was that of Michael Dudley.

He was carrying a considerable weight

in the pockets of his uniform,

which stopped the body from rising to the surface.

The weight being two packages

sent by gryphon mount technical services.

That's right,

including some high value jewellery.

But this still leaves

most of the consignment unaccounted for.

Cause of death?

Well, no obvious signs of serious violence.

Certainly no gunshot wounds or deep penetrating trauma,

but if you look at the hands,

you will see fractures on the fingers,

suggesting he scrabbled at something rather desperately.

At the Van door?

How about this?

He intends to dump the Van,

presumably with most of the gear on board,

he can always go back with scuba gear

and dive for it when the heat's died down.

Yeah, but what about the gear in his pockets?

Well, maybe he stashed a couple of packages

just to tide him over.

Go on, Brian.

Right, so when it comes to ditching the Van in the lake,

he doesn't get out in time.

So the Van sinks, but he can't get the door open

because of the water pressure, but he can't help trying.

So he breaks his fingers, clawing for the door handle.

No, but he wasn't found in the Van was he?

No, so, as the Van fills up with water,

the pressure equalises, then he can get out.

But by then, it's very deep,

too deep to get back to the surface.

Especially weighed down with all that bling.

So, the consignment's still intact

until somebody comes along and blows the lock off.

I'll tell you what, this is quite unusual stuff,

I'd say it was middle eastern.

Look at the big stones, yeah.

I've seen jewellery just like this,

and only the other day,

at the dive club.

Yep.

Same materials and same hallmark.

I reckon this little lot's worth about five grand.

You and Martin viner found the Van didn't you?

Yes.

When?

1995, before the decompression incident.

Martin wanted to find the deepest part of winfield lake.

We came across the Van.

When we surfaced, I said to him that we should report it,

but.

Go on.

Martin blew the lock off.

He was really pissed off to find out it was just parcels.

But then he opened a couple and, we were really careful.

Just opened one parcel at a time.

We sold the stuff at jewellers all over the country.

Not all of it, eh?

There was a few pieces I couldn't resist.

Silly.

What can you tell us about how Martin died, Trisha?

Martin had been getting threatening phone calls,

anonymous.

Saying what?

A man's voice said, "it's payback time.

I want what's mine, you know what I'm talking about."

And how did Martin react?

Martin just stonewalled.

He just said, "you got the wrong number, mate," and hung up.

When did this start?

After you came to talk to us.

[Suspenseful music]

We're gonna pick up sinclair again,

really lean on the bastard this time.

You want to come?

No, I'm sorry mate, I can't.

Bit of business.

Moonlighting for Palmer?

Look Jack, whatever may have happened,

I'm going sort it, trust me.

We found Dudley's body

at the bottom of winfield lake, Andrew.

Now once and for all, let's have the truth.

All the packages that should have been on the Van

were there, apart from the ones consigned

by gryphon mount technical services.

But a couple of those turned up somewhere else,

in Michael Dudley's pocket.

[Scoffs] That stupid, greedy ponce.

Couldn't help stuffing his pockets at the last moment.

Everything. All right?

Yeah, fine, yeah, yeah.

Any, er, joy with your inquiries?

No, not really. No.

But, er, if there are any developments,

do you want me to keep you posted?

You're worth your weight in gold, Gerry,

I knew you would be.

Forgive me, I'm in a bit of a rush.

Yep, see ya.

Gryphon mount just sent

the odd single package through us at first.

We knew it was something dodgy,

Mickey mouse company, false address.

So what did you do?

We had a look inside one of the parcels, jewellery.

Good stuff.

So what'd you do with it?

Resealed it, sent it on its way.

Then we were asked to collect

20 packages from gryphon mount, it was a bloody fortune.

And you decided to rip them off?

The idea was, Mick would dump the Van in a lake,

not winfield, another one,

then disappear, go abroad.

It would just look like another security guard going awol.

Oh, I see,

then Mick would wait till the heat was off,

dive and recover the gear.

You see it all.

So how did it all go wrong?

Marie thought we were leaving ourselves

in Mick's hands too much.

Nothing stop him ripping us off.

She reckoned she could always get inside a bloke's head,

when she'd taken him to bed.

She seduced him just to keep tabs on him?

Yeah.

That's pretty cold-blooded.

Did you know about this?

Maria and I understood each other, we were a team.

Whatever was necessary to get a job done.

But it didn't work.

No.

Mick wanted my gun in case it went bent on him.

He went to collect it at our house that morning.

Marie must have realised he was stitching us up.

Mick killed Marie, and left me to take the can for it.

[Tense music]

[Drawer rasps]

Did you threaten Martin viner in telephone calls?

No.

Did you kill Martin viner?

No, I don't even know who this Martin viner is.

There's a sophisticated security system

guarding viner's dive club compressors.

Now, you'd have to get past those to switch the tanks.

You were in a security business.

16 years ago.

There's been a technological revolution since then.

Andrew, you are still the prime suspect

as far as we're concerned.

No.

Listen,

I'll tell you the real story.

Brian, listen to this.

Steve Palmer's been in touch with wilmslow.

Yeah, he's offering him security services at winfield lake,

but at an unbelievable knocked down price.

No Brian, no Brian,

what this amounts to is

that Palmer is giving wilmslow a massive bung.

There was just one man

behind the whole gryphon mount deal,

Steve Palmer.

Palmer?

When Marie was killed and the Van went missing,

Palmer came down on me like a tonne of bricks.

I said, "there's no way I can give you your gear back,

I've been ripped off as well."

If he hadn't believed me, I'd be dead.

He settled for taking the company off me.

[Doorbell rings]

All right!

All right!

Hello, what can I do for you?

Why is Steve Palmer giving you a massive backhander?

What do you mean?

We've seen the quote,

Palmer's effectively handing your company

thousands of pounds.

Well, come on.

He got in touch just after you did.

All he wanted was to be kept up to date

about what was going on at the lake.

Why?

He never told me.

But what exactly did you tell him?

He was interested in osprey subaqua, viner,

that girl Trisha.

Then viner was murdered.

Nothing to do with me.

You try that in court.

Oh, bloody hell.

What?

Well Trisha contacted me.

She wanted access to the lake, today.

And you told Palmer?

[Urgent music]

[Suspenseful music]

[Water splashes]

So many lives, Trisha.

Who are you? What do you want?

What belongs to me.

What you and your friends stole.

There's nothing left.

I'm a businessman, Trisha.

Please.

If I can't have the jewellery,

I'll have the club.

A nice little going concern.

[Sandra] Palmer.

That'll do, Steve.

[Trisha screams]

Just think about it, Steve.

She's a fit young diving instructor, and you're sad old git.

Who d'you think's going to come out of that lake alive?

- [Trisha yells] - [Steve groans]

Have you read this medical questionnaire

you've got to fill in if you want

- to train to be a diver? - Eh?

You are to seek medical advice

if you answer yes to any of the following questions.

Are you currently taking any prescribed medication?

Yeah, well.

Hmm.

Have you a history of alcohol or drug abuse

in the past five years?

Five? That's a big stringent.

Have you any history of mental or psychological illness

of any kind, fear of small spaces, crowds, or panic attacks?

[Book thumps]

[Brian sighs]

I've wasted all that money.

Well, it doesn't have to be wasted.

We could always wear the rubber suits.
