You're going to be lucky for me tonight, Irish?

I don't know. Maybe.

Who you here with?

Your best tell your lickle boyfriend he's a bit too far east.

He's not my boyfriend.

What's he here for, then?

You can tell me.

Looking to expand business.

What business?

He's got customers -

Tottenham, Wood Green, Manor House.

Even looking at moving into Enfield.

It's just, he needs a bigger supplier.

Now, how am I going to sleep tonight if I don't know your name?

Kash.

Lisa.

So if I do business with them...

..do you come as part of the deal?

SHOWER RUNS

You've all worked your arses off on this one.

Don't think that's gone unnoticed.

This team's been trying

to infiltrate the TMC for a while now.

I know there's been pressure on all of us, from all sides.

For 18 months,

we've been trying to get inside those fortified doors.

So what we achieved last night is off the scale, the equivalent

of busting through a New York latch single-handed.

Inside that room, were enough AK-47s and ammunition

to take out half of Tottenham.

-We seized over 20 -K worth of crack.

We have Mark Bailey, AKA Kash and Adio Campbell, AKA Toxic,

with their fingerprints on the gear, which is a bloody first.

LAUGHTER

They've both been charged and are tucked up safely in Brixton

waiting a court date.

And all this thanks to one fearless officer, someone who always goes

over and above to get the job done.

Da Costa, on your feet, please.

A round pf applause for the man. No need.

Honestly, guv. I just did what any one of you'd do.

All right. All right.

Very good.

Da Costa...

..borough commander wants to see you tomorrow morning, 10:00 am.

Well done, sunshine.

CROWD: Ooh!

APPLAUSE AND LAUGHTER

Hi.

Go on, then, can I have a little cuddle?

Ah, whoosh!

So how bad was it?

17 hours of bed.

Thought I'd never walk again.

Oi, Ellie don't be giving them lot baby fever, yeah?

Otherwise there'll be no-one left in the office to make my tea.

And there'll be no-one to spit in it either, isn't that right?

THEY GIGGLE

As much as I'd love to cuddle you all day, sweetheart,

auntie Sadie's got a shit ton of paperwork to get done.

Oi, one of them Wombles called when you were out here bitching.

They want to see you about that Rachel Nickell murder.

TV: On Wimbledon Common in south-west London, a young mother, Rachel Nickell,

was repeatedly stabbed.

It appears to be a random killing,

which, of course, makes it extremely...

..in a ferocious attack

she was sexually assaulted and stabbed.

Her two-year-old son was found clinging to her body.

The murder has sent shock waves through the country.

An unsuspecting young woman murdered

in a busy, open space

in broad daylight.

TV: Police officers described the murder as one of the most horrific

they'd ever had to deal with.

They began an extensive search of the common to find

a murder weapon.

Public horror was made...

TV: Pressure is mounting on police who have still not made a single

arrest in the hunt for Rachel's killer.

Local residents fearing for their safety

are demanding action.

One police officer described it as the most horrific and frenzied

attack he had ever seen.

CHATTERING

CHATTERING GETS LOUDER

I know we're seven months in, Sir, but this is going to work.

Absolutely.

Once the Yard sign off on it, we're good to go.

Just..just give this a chance.

Please.

Guv.

Sadie...

Keith Pedder.

This way, please. You come highly recommended

SO-10.

Have a seat.

Well, you certainly fit the brief.

And you're SIO on Rachel Nickell's murder?

It's a feeding frenzy.

The tabloids are obsessed with Rachel.

She was beautiful.

Thanks to the press coverage it generated 5,000 lines of inquiry,

1,200 witness statements and 4,000 contacts with the public.

We've got an 1,100-acre crime scene, no forensics

and the only witness was a two-year-old kid.

We need a break.

So how is a covert officer going to help?

Have you heard of offender profiling?

Like the FBI?

Yeah, exactly.

I asked two criminal profilers,

Robert Ressler from the FBI

and English profiler Professor Paul Britton,

to examine the evidence, the crime scene.

Both came back with virtually identical profiles for the killer.

The minute I walked into his flat,

I could see it matched the profile.

Colin Stagg?

He's a near perfect match, but that's not why we arrested him.

When that went out on Crimewatch...

..half the estate rang in to name him.

I've got two witnesses

that put him five minutes from the scene when he claims

he was at home with a headache, watching a quiz show

that wasn't even on.

That's what he did to her.

The killer sexually assaulted Rachel Nickell.

He stabbed her 49 times.

All in front of her little boy.

Professor Britton's very sure about one thing...

..this isn't over.

He will kill again.

We've got nothing but circumstantial evidence against Stagg.

That's why we need your help, Sadie.

How?

We asked Professor Britton if he could design an undercover op

based on his analysis of the murderous deviant sexuality,

one that would either eliminate Stagg from the inquiry

or where he may further implicate himself.

We're calling it Operation Edzell.

The operation gives Stagg the space

to build a relationship

with a covert officer.

If he's guilty...

..reveal his involvement.

We want to put you right at the heart of it.

What would you want me to do?

Become part of Colin Stagg's world.

Gain his trust.

Play to what drives him.

We need you to indulge his darkest fantasies.

This job requires a very special officer, Sadie.

I'd like you to go and meet Professor Britten.

KNOCKING ON DOOR

Come in.

Professor Britton?

I'm DC Sadie Byrne.

I'm from SO-10.

Sit, please.

Can I offer you a cup of tea, coffee?

Er, tea, please.

Milk and one.

Do you prefer the milk added first or last?

Last.

Would you like me to stir it for you?

Or would you prefer to stir it yourself?

I don't mind.

Interesting.

Mr Pedder said that you would explain the operation.

Why did you choose undercover?

There are agencies to take men down for their crimes.

I mean, what woman wouldn't jump at the chance?

I read your profile.

It suggested that our killer is a man

with a powerful, deviant

sexual fantasy life.

Two years ago, Colin Stagg sent an unsolicited sexual fantasy

to a woman called Tracy Hynes

in response to her advertisement

in a lonely hearts column.

"I couldn't help spying on you...

..and what I saw you do really made my day...

..to see you wank yourself like that...

..really turned me on...

..and I was wondering if you would do it again right in front of me

so I can see up close.

Smiling, she says to me, "Undo my skirt,"

which I quickly do, and we are both naked.

She's getting so hot and excited, I can't wait any longer.

I grab her and push her face down into the grass...

..forcing myself into her."

It's a common sexual fantasy, sex outdoors.

Why do you think it interests me?

There's similarities between the attack on Wimbledon Common.

He uses violence.

He wants to punish and humiliate her...

..just like Rachel Nickell's killer.

This gives us a glimpse into Stagg's fantasy world.

It also gives us the perfect way in for you.

A way in?

We want you to write to him.

You play the part of Tracy Hynes' friend.

You saw the letter she found so offensive, but...

..it didn't offend you.

Rather, it aroused you.

Mr Pedder seems pretty certain that Stagg is your man.

Mr Pedder is a detective.

I'm a psychologist.

But if he's right, then you are going to be dealing with

an extremely dangerous man.

A predator.

Well, I've handled myself face-to-face with armed Yardies,

I think I can handle a pen and paper.

I don't think you've crossed paths with a man like this before...

..the sort of man who can only become aroused by dominating a woman...

..who derives pleasure from her...

..fear.

..from her total compliance...

..and utter humiliation...

..a man sexually aroused by the feeling

of a knife in his hand

and the sight, sound and smell...

..as that knife slices human flesh.

WHISPERS: You've got beautiful, blue eyes, Sadie.

Well done.

I think you're up to the task.

What exactly is the task?

To make Stagg fall in love with you.

SIREN WAILS IN DISTANCE

Sade! Sadie!

Be honest.

How old do I look?

20...ish.

And from behind?

Younger. Good.

He likes them young - last one was 16.

I swear to God if he doesn't pick me tonight

and Keira gets him tomorrow...

Oh, so you're off, then, are you?

Your best mate as being seconded to the Rachel Nickell case.

SHE LAUGHS

You going to wish me luck?

Come here.

Yes!

Oh, you lucky cow!

Enjoy it, mate.

Get to work, you tramp. Go on.

Hey.

What about me?

Don't get raped.

Come on.

Sadie.

HE SIGHS

This is not a trap.

This operation has been designed to allow Colin Stagg to either

implicate himself in Rachel Nickell's murder

or eliminate himself from the inquiry.

If he shares the same sexual deviancy as the murderer,

he will reveal it.

I've been through every detail with the Yard and they've agreed to it -

right to the top, lawyers included.

How long do you think it's going to take?

It should take between two to six weeks to establish a rapport,

and once the fantasy exchange has started,

you should have gone the rest of the way within two months.

What if he hasn't revealed any details

about the murder by then?

Then he's either got nothing to hide or he is never going to reveal it.

The important thing is you must never put words in his mouth

or ideas in his head.

You must only react to his cues.

Stagg must make the first move at every stage,

and we do not know where it will end, Sadie.

But it starts with your letter

introducing yourself as Tracy Hines' friend.

We're hoping that you'll build a relationship with Stagg

as a pen pal - we'll write the letters

but the content will be guided and approved by the professor.

You'll need to memorise your cover story to the finest detail -

childhood, school, family, friends.

Yep, I'm used to that.

You'll play the part of a disturbed young woman

with a dark secret in her past looking for a certain kind of man.

Dark secret?

A history of involvement in a Satanic cult.

You'll befriend Stagg and let it be known that you are...

..open-minded.

You know you are different from other women

but you can't explain why,

and you're trying to find out if he feels the same way.

Critically,

you must not express any interest in Rachel Nickell's murder.

If Stagg mentions it, you will show a...

..a passing curiosity but no more.

You can only engage him after he's brought up Rachel...

..three times,

and you must never introduce any violently aggressive

or sadistic fantasies into the conversation -

these two must come from Stagg.

You did realise this was going to be more than just writing letters, hm?

Well, I didn't think you were just after me

for my handwriting skills, did I?

"Dear Colin, I hope you're not offended by this intrusion,

"as we've never met before,

"but I feel like I have known you for years.

"You may remember writing to a woman called Tracy Hines.

"Tracy was an old friend of mine

"and a while ago when I stayed with her,

"while she was out, I read a letter that you sent her.

"I hope you remember because this letter has been on my mind

"and it interests me greatly.

"I find myself thinking of you a lot.

"I would be very interested in getting to know you

"and writing to you again."

"PS, my name is Lizzie."

So I haven't washed in a week, right?

I pissed on some clothes, put them in some plastic bags,

I mean, they stink.

I look horrendous, like proper crackhead vibes,

but I'm in there with them,

I have them right where I want them

and he's about to sell me the gear.

Then he just stops and stares at me.

Cos I've thought of everything, right,

my shoes, my clothes, my legends, everything,

and I think it's perfect,

but he has noticed one little thing.

Nice teeth.

HE CHUCKLES

No crackhead has teeth that clean.

And just like that, the whole lot was fucked.

So I'm checking everything, every little detail,

but I'll be fucked if I make another mistake like that again.

So you ready? Go.

How old are you? 28.

What's your star sign? Scorpio.

Good. Where do you go out?

Dublin. Who'd you live with?

I live alone. I like my own company.

Do you work?

No. I'm cat sitting. Do you like animals?

I love animals, especially cute little fluffy ones.

Favourite song? Real Wild Child, Iggy Pop.

Biggest fear? Spiders.

What do you look for in a man?

Snap.

You've got to go deeper.

And maybe it's a bit "dumb blonde"

with the fluffy animals and arachnophobia.

I mean, Rachel Nickell was proper smart.

She went to grammar school.

Yeah, but he didn't know that, did he?

He didn't look at her and see like, "Oh, I'm into her brains," did he?

No. But if he watches the news, he knows now.

I'd work a legend that feels a bit closer to Rachel.

Play her a bit smarter.

They're right about this man - he's going to kill again.

I mean, this isn't dealers or nonces, is it?

You're bait for Rachel Nickell's killer.

I know what I've signed up for. Do you? Yeah.

Do you?

Cos it's a different world, Sadie.

Neither of us have done a job like this before.

Everyone and his dog's got his eyes on this one.

All I care about is keeping you safe.

Then we'd better go again - shall we?

"Dear Lizzie, thank you so much for your letter,

"which I read with great interest.

"I think we have a lot in common.

"I live a quiet life with my dog, Brandy.

"We like walking over the local park.

"I'm five foot seven with dark hair.

"I do a bit of weight training.

"I don't like being told how to live my life.

"We must each find our own paths to travel along.

"I do not like people who are close-minded,

"small minds, small intelligence...."

"I can, if you want, enclose personal letter with this one

"about a fantasy I've had since you wrote to me.

"Love, Colin."

He enclosed a fantasy -

so he gives Lizzie the option and then he takes it away.

He's already trying to control her.

Which may or may not be significant.

It rather depends on the content of the fantasy.

"We're in my garden on a hot summer's night.

"Luckily, all the neighbours are in bed so no-one can see us,

"but the thought that someone might excites us both.

"You lay on the warm, damp grass holding my hand.

"I sit astride you...

"..slowly masturbating myself as I stroke your hair.

"You're laying there smiling.

"I would very much like it if I could send you letters like this one

"about my fantasies, about us being together.

"Love, Colin."

Sex outdoors, being watched.

It's an unexceptional fantasy,

nothing more than you'd find in a gentlemen's magazine.

There's nothing in it to suggest he's our killer.

But he's taken the bait, hasn't he?

He's writing fantasies to her from the off.

Let's write back. It's too soon.

We'll wait a week.

What about his request about a photograph of Lizzie?

Well, he might get suspicious if we don't send it.

I think maybe it's time we show him who Lizzie James really is.

Lizzie James, Lizzie James.

Ten, nine, eight, seven, six,

five, four, three, two.

"Dear Colin, your letter was certainly enlightening

"and I enjoyed reading your story.

"If I close my eyes,

"I can almost feel you sat astride me

"and feel your weight pressing me into the grass.

"You really write well,

"and I bet this is just the tip of the iceberg

"when it comes to your thoughts.

"There's a lot more to you than meets the eye, Colin.

"I'm sure your fantasies hold no bounds

"and you are as broad-minded and uninhibited as me.

"Write soon, Colin.

"I can't wait to get your letters in my little hands.

"Love, Lizzie."

TV: Colin Stagg was a self-styled pagan.

He'd been on the common that morning and resembled an early Photofit.

When they went around to speak to him, they found an altar...

A man arrested in connection with the murder of Rachel Nickell

on Wimbledon Common has been released

after being questioned for two days.

29-year-old Colin Stagg appeared at Wimbledon Magistrates' Court

today and received... TV AUDIO STOPS

TAPE PLAYER WHIRS AND SQUEAKS

TV: The brutal murder of Rachel Nickell

in front of her two-year-old son in July shocked the nation.

The 23-year-old former model was walking her dog with Alex

on Wimbledon Common in broad daylight when the killer struck.

Police describe the murder as one of the most horrific they've ever...

TV AUDIO STOPS

DOOR OPENS AND CLOSES

It's good to see you again.

Are you keeping well?

Yeah, I'm fine, thank you.

We received...

..another letter this morning.

SHE SNIFFS

He enclosed another fantasy.

Sadie.

"I will grab you by your hair

"and drag you screaming into my bedroom.

"I will rip your clothes off.

"I ask you...

"I'll make you pay for being a dirty slut as I force you to your..."

Can you just read that?

"..to your knees.

"I place a stool in front of you and force you over it,

"I take a leather belt from my drawer.

"I place it over your mouth and hold each end, pulling your head upward."

This goes way beyond control and humiliation.

He wants to hurt Lizzie.

It's a clear escalation.

The violence here is more extreme than that carried out by individuals

who derive pleasure from symbolic enactments

of deviant and submissive sexual roles...

..yes. He ends it, "I hope this is what you wanted."

What woman would want that?

It is a clear indication of the deviant sexuality

predicted of Rachel's killer, I grant you.

But it isn't of the specific nature of the violence

exhibited in the murder itself.

There's no mention of a knife.

Exactly.

Dear Lizzie.

I'd love to know more about what happened in your past.

You've got me wondering about your secret now.

I want to dominate you, take your body as my plaything.

I want to and will give you a fucking good sorting out.

You need a damn good fucking by a real man.

And I'm the one to do it.

By the time I'm finished with you, you're going to be so sore.

I'm going to make you work hard for me.

You'll be my sex slave.

I want every fantasy of yours in my mind.

Every kinky detail, every randy thought.

Anything you want, you'll get.

By God, you will get it.

I'm going to make sure you're screaming in agony when I abuse you.

I am going to destroy your self-esteem.

Ah, good evening. Thank you for coming this late notice,

I know you're all incredibly busy.

It's, er...it's good to see you.

OK. Now we want to move this forward.

The letters are working and Stagg is, um...

Oh, lights, please.

Stagg is starting to reveal his true self through his fantasies.

But we think the chance of a confession

is unlikely to come in writing.

And that's why, with your permission,

we want to move Operation Edzell to the next stage.
