DCI Banks

- Josh Tate. - Student? - Second year at Uni.

I saw him yesterday morning. He was heading out as I was getting up.

- And you are? - Melanie Thomas, Spence's girlfriend.

It seems he wants something a bit more permanent.

He's asked me to marry him.

I've just seen the next 10 years mapped out for me.

Work and you.

What's he doing at a lap dancing club?

He's only ever here for Melanie.

Piperonyl Methyl Ketone.

PMK is used to synthesise ecstasy.

You make it look like Josh had it coming

- and that way nobody cares that my son died. - I care, Mrs Tate.

His name's Martin Hexton. He was the undercover officer

we used back when I was in the crime squad.

I've forgotten how much it meant to me, our time together.

Josh was supplying Fallon with drugs.

Were you helping, Dr Calcutt?

Serious head injuries. Victim is Liam Fallon

We picked up Josh on a traffic camera

- and this guy was following him. - That's Martin Hexton.

You're involved with Hexton and he's now a suspect.

- No, I'm not. I'm not involved with Hexton. - Please. Helen.

- You Banks? - DCI Denmoor?

Hexton infiltrated drug gangs.

Either he teamed up with one of 'em

or decided to go out on his own.

Either way, it was my fault.

You can't blame yourself if one of your officers chooses to go rogue.

Copies of Hexton's recent targets

and the case papers from his trial.

Thought they might be useful to you.

Look, corruption's one thing

but do you think Hexton would go as far as murder?

The thing about undercover is, you get used to crossing the line.

Hexton's been doing it so long

he doesn't even know where the line is.

Martin Hexton's case files.

I want you to go through them inch by inch.

- What are we looking for? - I don't know but there's a good chance

that Hexton's working for a drug gang he was investigating.

Given that we know that Josh Tate was selling his ecstasy tablets

to Liam Fallon and that Hexton was watching the pair of them

- there could be a connection. - You think it's sort of turf war?

I don't think anything at the moment.

Go through the file, see if you can find a concrete link

between Hexton, Fallon and Josh Tate.

What's the verdict on Fallon?

Hospital said he's stable, through the worst of it.

Good, let's go and talk to him.

Tariq, where are we with locating Hexton?

- Service provider's put a trace on his mobile. - And the car?

- Circulated the index to all units. - Why aren't we asking Helen?

If she knew Hexton from before then she might have an idea where he is.

DI Morton's taking some time off.

- I'm sitting in the front! - No, I am!

So come on, Helen Morton doesn't take time off. What's going on?

It's personal. You're enjoying this too much.

Actually I'm just relieved it's not me in the doghouse for once.

There's still time.

Speaking of time, when are you planning on giving David your answer?

- When I've made my mind up. - Still got some doubts, then?

Well, I wouldn't be human if I didn't.

Unbelievable.

Someone assaults me in my own home

yet I'm the one that's being questioned.

You are under caution, remember? Beverly Calcutt's confessed.

She said that you were buying the pills

that you and Josh are making in the garage.

You WILL be arrested the moment the doctor gives us the all clear.

So who attacked you last night?

Was it him?

I don't know. I didn't see the guy.

What do you mean, you didn't see the guy?

I swear. I came home and I saw that someone had moved by stuff.

I heard a noise behind me and then, bang.

Next thing you know I'm waking up in an ambulance.

It wasn't a burglary, Liam!

This man was a professional, he didn't even leave a print.

You were attacked because of your drug operation with Josh Tate.

Look, I don't know what you think we were into, OK?

But all we did was pass the stuff on.

Yeah, we made a bit of money but we didn't tread on anybody's toes.

So, do you think Fallon is telling the truth?

I think he's got good reason to lie.

But if we doesn't really know Hexton how does Hexton fit into this?

- Hey, is everything all right? - Oh, everything's great.

She said, "Daddy."

- You're a clever girl. - Ha ha!

Well, sounded more like a 'do do'

but we both knew what you meant, didn't we?

- Alan. - Hey, David.

Hey.

I'll see you upstairs.

So you came all the way here to tell me she said, "Daddy."

Well, we were on our way to swimming but yeah,

essentially that's why I'm here. It's a big day for me.

I know. Did you say anything else?

No pressure but she did ask about her bridesmaids dress earlier.

- Her speech really is coming on. - Ha! She's very advanced.

Sorry, I've really got to be somewhere.

I love you. See you later.

Come on.

- All right? - Thanks for coming.

Sorry about all the cloak and dagger.

It's all right. It appeals to my inner spy.

- So what's he saying? - The boss?

Not much.

- He's not happy. - Mm.

Just tell me what's going on with you and Hexton.

Nothing.

At least not any more.

- Do you know where he is? - No, I thought you would by now.

No, it seem he's involved with various drug gangs.

Oh, I doubt he'd go that far.

We're looking to Hexton's old case files.

Hopefully we'll find a connection between him and Josh Tate.

Sorry, Annie.

Sorry, there's... I need to go. There's something I need to check on.

OK.

Hexton. Clocked at a 24 hour garage two miles north of the centre.

- Show me. - He was there at 11:46 last night.

According to the till receipt

he bought petrol, water, crisps, chocolate and two travel blankets.

He's settling down for the night.

He wouldn't check into a hotel, he's not that stupid.

He slept in the car. Right, get some units out there.

Check everything within a mile radius of that garage.

Service provided just called. Hexton turned his phone on an hour ago.

- You got an exact location? - Beech Avenue in Alwoodley.

That's where the Fosters live. Come on.

What's Hexton want with them?

Mrs Tate?

I have some questions I need to ask you.

- Is that you in the picture? - Where did you find that?

That was taken in 1993, wasn't it?

When you were a member of a group called Radical Action.

It was a long time ago.

And this man standing here beside you...

Do you remember him?

He was in the group for almost 18 months.

He gave his name as Martin Wells but in fact he was an undercover officer.

He testified against the group

and four of your friends were jailed, weren't they?

That man betrayed me.

18 months is a long time and it's not unheard of

for an undercover officer to form relationships in these situations.

But Mrs Tate,

I have to ask the question...

He's Josh's biological father.

It's no point in keeping it secret any more.

- Why didn't you tell us this before? - Cos it wasn't relevant.

You know, I brought Josh up as my own.

I'm his real dad.

- What's going on? - Mrs Foster, have you seen anyone

hanging around the house this morning?

- No. - Any visitors? Any calls?

Er... Just the detective.

- What detective? - He came to take Melanie

to the station for questioning.

Ken, he's taken Melanie.

Circulate it to all units!

All units from DC Blackstone. Suspect is in a black saloon

last seen on Beech Avenue in Alwoodley.

Stop the car!

I want to get out now!

- Let me out! Let me out! - Not until we talk!

Let me out!

Melanie, stop!

I just want to talk.

Leave me alone!

Melanie! I just want to talk to you!

Come back!

Oh, God. What's happening?

Don't worry, come on.

Please help me...

All units from DC Blackstone, suspect is in a black saloon.

Index, Papa, Yankee, Five, Three, Juliet, Yankee, Lima.

Vehicle was seen heading south on the Leeds Road.

All units respond.

'All received by DI Morton.

I'm on the Leeds Road.'

I thought she was having time off.

From DI Morton, I'm now following the suspect

'DI Morton, what is your location?'

'Still heading south into the city.'

Need some help here!

Come on.

Don't worry, they've got you now.

Here you are, love.

What happened to her?

Where's the driver?

DCI Banks to DI Morton, come in.

Martin.

Why didn't you tell me about Josh?

I couldn't tell anyone.

Yeah, well, now they think you killed him.

- I thought Fallon killed him. - No.

It's not how it looks.

You used me, didn't you? To get Fallon's name?
