Morning, Sarge.

Morning. Who's this?

Uh, business card says Aaron Samuelsons, locksmith.

Lambeth address.

Blood on the brickwork behind him suggests

probable cause of death as head injury

after being slammed into the wall.

Someone really didn't like this Aaron Samuelson.

Tallies with his wallet still being in his pocket,

this wasn't a robbery.

The phone isn't password protected.

It looks like the majority of the calls are from

a Stacey Ford, work and home.

Presumably, this is her.

Have I seen him before?

Dunno, might be on the system.

Gambling man,

maybe had a run in with someone he owes money to.

Mmm, maybe not.

Okay, Billie and I will go and break the news

to this Stacey Ford, can you finish up here?

Yeah, of course.

Aaron Samuelson was called out on a pay as you go,

no subscriber details and it was only used for one call.

-So, it was a set up? -Mmm.

Billie thought she might recognize our victim.

She was right.

This could get personal for her.

Um... Aaron got a call out, an emergency one, you know?

Um, someone locked themselves out of their car

and he was all up about it 'cause it's easy money.

Called them his bill payers.

What time was this?

Um...

I was heading out for work, I start at 10:00,

well I'm a cleaner, I do the night shift.

So, um...

9:15.

Yeah, yeah, that's the last time I saw him.

We found a card for a gambler's support group in his wallet.

What?

Would you know if he was in debt?

Aaron wasn't a gambler. He was a decent man.

He kept himself to himself and he barely went out.

If we ever argued about anything, it was that.

He could stay in all week.

No fall outs with family?

He didn't have any.

What about friends?

Aaron moved down from Lincoln two years ago, three.

Worked for himself, not much chance to make new friends.

How did you two meet?

The way everyone meets, online.

We just spoke to the girlfriend and got nothing.

Maybe a bit too much of nothing.

Aaron Samuelson had no family or friends.

Anywhere on the financial records?

Just about to fill the boss in.

Why don't we, uh, go into my office?

Billie, can you line up what we know so far, please?

Uh, sure, boss.

If this is about the Chief Superintendent,

I'm still thinking about the best way to approach him.

It's not about Mulgrew.

-Rob. -It's about Billie.

Aaron Samuelson isn't our victim's real name.

His fingerprints are a match for a Leon Renton,

in the system for minor shoplifting when he was 18.

Okay.

Leon Renton was the key witness

for the prosecution in the trial against an old school mate

of his called Kit Hughes.

Hughes was convicted of manslaughter ten years ago.

Am I supposed to know that name?

It's who Hughes killed.

Billie.

I recognize the victim.

His name isn't Aaron Samuelson,

it's Leon Renton.

He testified against the guy that killed my dad.

But you already knew that.

This is Kit Hughes, he got 12 years for manslaughter.

What happened?

My dad was walking through Dalston

when he saw these two, Kit Hughes and Melanie Palmer,

giving Leon Renton a kicking.

And he stepped in?

Yeah, next thing, Kit Hughes went for my dad.

Dad hit his head on the pavement and died.

Did your dad know any of them?

He taught all three

when they were at school, a couple of years before.

Why manslaughter, not murder?

Hughes claimed in court that it was self defence,

that my dad hit him first.

What did Leon Renton testify?

Leon swore that Kit Hughes provoked my dad

by whispering something that set him off.

And if Hughes was provoked, it was manslaughter, not murder.

What did Hughes whisper?

Leon didn't hear what he said, which meant it was disregarded.

Why were Kit Hughes and Melanie Palmer

attacking Leon in the first place?

That never came out, even at the trial.

Surely, Leon Renton's murder has nothing

to do with my dad's case?

Kit Hughes is still inside.

Billie,

Kit Hughes got early release from prison, three weeks ago.

I'm sure your mum's fine.

If Kit Hughes is settling scores,

my mum's the one who persuaded Leon to testify against him.

Voicemail.

Is that usual?

Sometimes she forgets to turn her phone on,

she's not answering at home either.

Why don't you go and see her? Put your mind at rest.

-Thank you. -I'll drive her.

They said my dad had a massive brain bleed.

Kit Hughes left him to die on the street,

I was in double maths.

School secretary came in with the head,

took me outside, I thought what have I done this time?

But I could tell by the look on their faces,

something terrible has happened,

then I saw my mum, down the corridor.

It's fine. Come on.

Chief Superintendent?

-Sergeant. -Can I have a word?

Jack.

Um, now that we're working in the same building

and after all that we went through.

Hmm, not the best way to describe our marriage, is it?

No. Well I wondered if we should go for a drink or something?

Yes, I-I-I'd love that. Um...

Tonight suit you?

Yeah, great.

Looking forward to it.

I've got a date tonight with my ex-husband.

Thanks. I know this isn't easy.

It's worth finding out what Kit Hughes

has been up to since his release.

-And Melanie Palmer. -I'll get onto it.

How did your mum persuade Leon Renton

to give evidence against Kit Hughes?

Just... she knew his mum through church,

they, they both put pressure on Leon to do the right thing.

This is it, stop, stop here.

Mum! Mum!

-No keys? -No, they're in my flat. Mum?

She might just be out, you know?

Mum?

She's not answering her mobile, she's not calling me back.

Mum!

Hang on, you... Are you sure...

Mum?

Mum? Mum, it's me.

She's not here.

-I've called the police. -Mum?

Mum, where have you been? Why is your phone off?

You scared the hell out of me.

You broke in? I thought I'd been burgled.

I mean... What on earth?

You were off the grid, Mrs F.

Billie was having a bit of a mare over it.

Sorry about the glass, we'll sort something out.

Mare about what? What's happened?

Mum.

Mum... it's Kit Hughes.

-He's been released. -Well, I know that.

I just don't understand what that's got to do

with you breaking my window.

You knew Kit Hughes was out?

Yes, I had a call from the probation service.

I thought about telling you, but...

You thought?

What the hell, mum?

I better cancel your mum's 999 call.

Billie, I'll let the Detective Inspector

know that everything's alright.

-Good to see you again, Mrs F. -You too, Rob.

Cup of tea?

That's exactly why I didn't say anything.

I didn't want you reliving everything.

So you'd rather I just bumped into Kit Hughes

on the street then?

You must've known with good behaviour,

he was near the end of his sentence, so

why discuss the obvious?

Why discuss anything at all?

Leon Renton was found murdered this morning.

I think it might've been Kit Hughes.

I can't believe it.

I'm sorry.

I know you had a lot of respect for Leon and him for you.

Leon's dead

and you're saying that you know it was Kit that did it?

He's a suspect.

Oh, no.

No, that doesn't make sense,

Kit's only just been released, he changed in prison.

That's what the probation report said.

Some people can make you believe anything, mum.

Can you detail your whereabouts for yesterday?

I spent the day with my dad at his place.

That's where I've been paroled.

I went to evening worship at 6:00

and I met my outreach worker here at 7:00.

He asked me to be part of a group session

with some of the kids.

We got talking after and I've got a 10:00 pm curfew,

so he let me sleep on the sofa in his flat next door.

He's out at the moment, but do you want his number?

Please.

Have you had any contact with Leon Renton

or Melanie Palmer since your release?

Nah, nothing. Please, check my phone.

Do you have more than one phone?

Nope.

It's a shock, Leon's death.

I've obviously thought about him a lot when I was in prison

and nowadays, after ending my penance, he's dead, it's...

Look, I did a terrible thing to Mike Fitzgerald and his family.

I intend to spend my life making up for it.

I've swept away your offences like a cloud,

your sins like the morning mist, return to me for I've--

For I have redeemed you.

I would like your phone

so that I can transfer the data on to this laptop,

with your permission.

Of course, I'm just happy to help.

How was it?

Uh, well, he's found God and you know, each to their own, but

he's wearing that a bit thick.

How about an alibi for last night?

His outreach worker said that he was at the centre all evening

and that he stayed with him between 10:00 at night

and 7:00 in the morning.

Seriously?

We might have to accept that Kit Hughes

has nothing to do with it.

Sarge, Hughes is clever.

I'm sorry, Billie, but as regards any evidence,

the guy's in the clear.

Uniform have just got Melanie Palmer out of bed,

she's on her way in.

I'm Detective Sergeant Vivienne Cole

and this is Detective Inspector David Bradford.

Can you tell us when you last saw Leon Renton?

Years ago.

He moved away, didn't he?

He moved back two, three years ago.

Last night, someone murdered him.

What, do you think I had something to do with it?

I never even saw him, I've never killed anyone, that's mad.

No, but you stood back while other people got killed.

Can you tell us what you were doing between

10:00 pm yesterday and 7:00 am today?

Bottle of vodka and a movie.

So that's me.

Get a lie detector test if you want, but I didn't kill no one.

What?

It's Hughes' mobile,

there's calls to your mum and vice versa.

What, so my mum's gonna be treated as suspect now?

No, your mum's gonna be treated like a relevant witness

who hasn't told us all that she knows.

Rob, invite Mrs. Fitzgerald in for interview, please.

Boss.

Oh, if only to finally see the place.

-Thanks for coming in, Mrs. F. -You're welcome, Rob.

Though I did have to ask a neighbour to

keep an eye on my front door.

Sorry, we'll sort that a glazier.

I brought something in,

didn't know but you like a biscuit, don't you?

Thank you.

The Detective Inspector won't be long.

-Right. -Please, take a seat.

Your mum brought biscuits.

Oh.

Thanks.

Mmm.

How can I help you?

I've asked you to come in because

we're investigating the murder of Leon Renton.

And because you made an impression

on Leon that led him to give evidence against the man

who was responsible for your husband's death.

I understand.

Good.

Had you seen Leon Renton since he came back to London?

He came to see me about a year ago.

You haven't seen him or talked to him since then?

No.

But you have had contact with Kit Hughes?

Yes.

What were those conversations about?

They were about his work at the outreach centre,

living with his father and his feelings about the past.

You know, Billie and I,

we both had to find our own ways to deal with her dad's death.

Hmm.

She stayed angry and I understand that,

but... I just couldn't cope.

Waking up, every day to that awful, gut wrenching rage.

I knew I had to find a different way if I was gonna get through.

Hmm.

And I didn't think Billie would understand.

So, that's why I kept these things from her,

not because I have anything to hide, but because...

it was the only way I could go on with my life.

During your dealings with Kit Hughes,

can you recall any comments or feelings he expressed

about Leon Renton?

Only remorse,

about what happened that day to my husband,

Billie's father.

And during your dealings with Leon Renton,

did he ever mention

what the original fight was about?

The one my husband tried to stop?

Yes.

Well...

I don't suppose the truth can hurt anyone now.

A week before Mike Fitzgerald was killed,

three people on mopeds

robbed a security guard outside a jewellers in Bethnal Green.

They struck it lucky,

the guard was carrying jewellery worth nearly 50 grand.

The guard wasn't quite so fortunate,

one of the gang cracked him over the head

and he was in hospital for a month.

So, these three on mopeds, was that

Hughes, Palmer and the third one our victim?

Billie's mum told me Leon Renton claimed he had no part of it.

According to Leon, Kit Hughes and Melanie Palmer

accused him of finding out where they'd stashed the proceeds.

And then stealing them.

That's what they were fighting about

when Billie's dad found them?

50 grand's worth of jewellery,

takes a lot of patience to sit on that for ten years.

What if Leon had started to sell it and someone found out?

I checked in with pawn brokers local

to Leon Renton and Stacey Ford,

one of them was offered a yellow diamond ring

couple of weeks ago.

The guy didn't take it because there was no provenance,

he was concerned it might've been stolen,

so he kept the CCTV.

Stacey Ford.

So, Stacey,

you were arrested on suspicion of handling stolen goods.

When you were searched, this ring was found in your bag.

The ring matches one that was stolen

from a jewellers in Bethnal Green, ten years ago.

It looks like the same ring.

Did Leon find out you were selling his stash?

He never knew.

There was a reason that Leon

still had that jewellery after ten years.

Putting that on the market and selling it

would've drawn attention to himself

and proved that he took it in the first place.

I'm showing Miss Ford Exhibit RB23,

a rucksack that was found during a search on her home address.

The bag contain two items

that also match those that were stolen in a robbery.

Exhibits RB24 and RB25.

I owed a grand, yeah?

That first necklace I stole got me 700 quid.

So, you're the one with the gambling problem?

I kept selling

and I kept gambling until there was just these three items left.

Then what happened next?

If I were you, Stacey, I'd do everything you can

to help us catch the person that killed Leon.

Uh...

My pawnbrokers weren't interested,

one said he'd put the word about for a percentage.

When he sent out the photo of the ring,

I was amazed he heard back so quickly.

What was the arrangement?

Uh, we met in a cafe in Hackney

three days ago.

Did you take the ring?

No...

uh-huh-huh, just to talk about money,

I-I-I wanted to see if I could trust her.

Her?

What was her name?

She called herself Alex, said she was owed the ring,

said she knew Leon of old guessed I was his girlfriend.

She said I had to give the ring to her

or someone would get hurt.

I'm supposed to be meeting her today,

she text me this morning, she still wants it.

Then you're gonna meet her.

No. No, no I can't do that.

Detective?

Detective Constable Fitzgerald.

-You're? -Marsha's daughter.

Mike Fitzgerald's daughter, yeah.

I heard you were a police officer.

Yeah, in conversations with my mother.

In prison and since your release and then they're gonna stop,

do you understand me?

I do.

I think Marsha's found them useful, but--

Stay away from my family.

Look, I don't wanna cause any of you any more pain,

I never expected any forgiveness,

your mum, she's a blessing.

Shut up, just shut up.

What did you say to my dad that made him so angry that night,

provoked him into having a go at you before you killed him?

I didn't say anything. Leon was lying.

You're the one who's lying.

Whatever you said meant you got away with murdering my dad,

'cause that's what this was, murder.

-Look, I'm sorry for what I did. -Stay away from my mum.

Billie.

-Do you have a minute? -Yeah.

Sit down.

You alright?

Has there been a complaint?

About?

I did something I shouldn't have done.

Well it hasn't reached me.

Will it?

I went to see Kit Hughes,

to warn him off contacting my mum.

No one want this for you.

I'd probably camped outside his door myself but

don't sacrifice your career over him.

Your dad wouldn't have wanted that.

We haven't got any evidence,

no forensic, no DNA or prints that put Hughes at the scene

and he has an alibi.

He's not a suspect.

Yes, sir.

Go and spend some time with your mum.

And no detours.

Thank you.

Why is she not here?

Calm down, give it time. You've got something she wants.

David told me you're meeting the Chief Superintendent tonight.

How are you feeling about that?

Well, there's a lot riding on it.

Safety of your family for one.

Yeah, my family are safe. I'll make sure of that.

Yeah, but you can't see them.

Do you really believe the Chief Super's

linked to these three murders?

He's not a killer, I know that.

But he's weak, I believe he's been manipulated.

So what are you planning on saying to him?

Well, I wish I knew.

Let's hope you're right

and whatever he's got himself into, he wants a way out.

How much longer? I told you I don't want to do this.

Now take it easy, remember to get her talking,

dig a hole for herself.

We're just over the road.

Surprise, surprise, Melanie Palmer.

Stacey, stop talking, start playing with your phone,

she's just walking in.

-You brought it? -Yeah.

Well, hurry up then.

Why don't you make it a bit more obvious?

So you're not gonna hurt me now, like you did Leon, right?

I mean you got what you wanted.

What?

Nothing.

Leon's dead.

I heard.

Keep quiet about this

and then I won't have to come and find you.

I'd have liked a bit more of a confession.

What about my money?

I told you, it wasn't yours to sell.

It was mine, Leon was greedy,

should've finished him off ten years ago.

That's good enough for me.

She's leaving, she's got it.

Who you talking to?

Try me.

-Give me your hands. -I'm gonna search you.

Can I go now?

Not yet.

Melanie Palmer, I'm arresting you on suspicion of the murder

of Leon Renton.

You what?

And for handling stolen goods.

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

if you do mention when...

We're not that bothered about a ten year old robbery, Melanie.

If you had nothing to do with Leon's murder,

tell us the truth.

Okay.

We robbed the jewellery.

But your lot showed up,

so we all went different ways, Leon had the bag...

he reckoned he ditched it in the chase.

Yeah, right.

I owed a lot of money back then.

I was desperate.

So I helped Kit beat Leon up.

And what about now?

Why would I kill Leon?

Finally getting my share of the job.

Listen, I'm not the one who ended up doing time

for killing that teacher.

Are you talking about Kit Hughes?

-He could never let anything go. -What do you mean?

Mr. Fitzgerald got Kit expelled from school, for violence.

And then, there we were,

giving Leon a kicking, for ripping us off,

suddenly, Mr. Fitzgerald's coming out of nowhere,

trying to stop Leon from getting his head kicked in.

Kit just starts laughing in his face, taunting him.

About?

Oh, um...

Mr. Fitzgerald's teenage daughter.

Saying what he'd like to do to her and that.

Mum! Mum!

I've got a guest.

We talked about this.

I got fed up waiting for your lot to fix this window,

so I asked Kit to come and help me patch it up.

Welcome to come in.

Mr. Fitzgerald, he just, he goes crazy, screaming at Kit

to keep his hands off his daughter.

Which gave Kit an excuse to really put the boot in.

I mean, like he said after, he'd been waiting a long time to

wipe the smile off Fitzgerald's face.

Kit Hughes puts himself out as a reformed character these days.

He has an alibi,

his outreach worker vouched for him at the time of the murder.

Grant Jennings?

What?

He's Kit's cousin.

-I wanted a chat. -Well, let's have a chat.

Oh, Billie, what do you want, huh?

Can you not see that this...

makes me happy?

Your mother's a very spiritual person.

This is not a conversation that you're a part of.

We have to share what's inside

or we can't understand each other.

Do you have to talk like that?

It matters.

I'm sorry, but it means something to me

that Kit wants to talk about who he is now.

It mattered to me that Leon got a decent job,

all that responsibility after

everything in his past, that he could share that with me.

Mum, did you meet with Leon?

Grant Jennings and Kit Hughes are cousins,

but with different surnames.

Something Kit Hughes neglected to mention.

So, Kit Hughes' alibi for the murder of Leon Renton.

Is looking decidedly shaky.

I'll get Hughes picked up on suspicion of murder

and perverting the course of justice.

You told my Detective Inspector

you hadn't seen Leon in a year, did you lie?

Of course I didn't lie.

After I'd spent time talking to Kit,

I had a yearning to go and speak to Leon,

I went to Leon's house but he wasn't in.

When was this, mum?

Yesterday.

I phoned Kit Hughes' dad,

he isn't there and he hasn't been back to the centre.

Control, officer requiring urgent assistance,

Belford Road, E14.

That's Billie's mum's address.

Did he ask you where he could find Leon?

I would never ask Marsha for that.

You went to Leon's house, mum?

Well, yes, and only because I wanted Leon to know

how different Kit was, that he had nothing to fear.

Mum, he followed you,

he saw Leon's car that he was a locksmith

and he called him out last night.

Kit, you played my mum, so you could get to Leon

and then you killed him, didn't you?

No, it's not true.

Look, maybe I should just go.

Look, no. Wait.

Billie, please, stop this,

Billie, please, listen to me, please.

Control, officer is confronting murder suspect,

the name Kit Hughes.

-Please. Just wait a minute. -Mum. Mum.

Wait a minute, Kit. You don't understand.

-Mum. -He's try...

Please, just wait a minute, okay? Billie, please.

Mum, I can't.

-Get away from the door. -Leave her alone.

-Get away from the door. -Just put the knife down, Kit.

Get away from the door.

Don't know what you want from me.

Oh, be quiet. Tell your daughter to do the right thing.

-I welcomed you into my home. -Do the right thing.

Units attending, Belford Estate,

suspect has a knife.

Okay, Kit, I'm moving away from the door, alright?

-Now leave. -Oh!

Suspect exiting Carters Estate, E14.

Argh!

Please, help me.

Please, help me.

You gotta help me.

Billie! Billie!

Are you alright?

It's gonna be alright, mate, it's alright, it's alright.

Right, just stay calm, yeah? Stay calm.

Billie!

Ambulance message, Carters Estate.

Detective Constable Fitzgerald.

Received.

Practice breathing.

-Alright? -Hey.

Kit Hughes is out of surgery.

And with the evidence we've got,

he'll be going down for Leon's murder.

Like he should've done for your dad's.

Good.

We're looking after your mum,

she was a little shaken up.

Don't know what I'm gonna say to her.

There's naive and then there's...

Just be there, I reckon.

I don't know what I would've done if you hadn't shown up.

I wanted him to die.

I wanted him to feel the life draining out of him like my dad.

I'm no better than him.

You're a copper.

And you're decent.

And he's a lowlife who deserved what he got.

And you would've done the right thing.

Going my way?

Um... sure.

Thanks.

They do food here, if you're hungry.

You always did like tapas.

This isn't a social occasion.

Really?

Well, when you said let's go for a drink

after all we've been through, I uh...

assumed you wanted to talk about us.

Why on earth would I wanna do that?

Yeah, I'll say one thing about you, Vivienne,

you may be a cold-hearted bitch, but

at least you're consistent.

When you said it's over, it was over,

didn't see you for dust.

Do you really not know what it is I wanna talk to you about?

You should go.

And if anyone were to see us,

you're just having a drink with your ex-wife,

for old time's sake.

And what are we really doing?

Well, um, I'm a police officer, helping a fellow officer

who, I suspect, is in a whole load of trouble.

Not here, darling.

No, I know, I know, don't worry about that now.

I was thinking, shall I pick up some fish and chips?

Yeah, like dad used to.

Take away treat night special, yeah.

Okay, just wait for me,

I've... yeah, I'll phone you when I'm on my way up.

Okay, see ya.

Billie, I wanted to say,

your instincts were good.

I didn't go about it the right way.

I know today's been hard, just...

make sure you learn from it.

Thank you, sir. Goodnight.

Vivienne's gone to meet Mulgrew.

Do you think she can persuade him to talk?

Well, if she can't, I don't know who can.

Time was you couldn't stand the Sarge.

-What's changed? -I got to know her.

Vivienne is one of the best detectives

I've ever worked with.

Oh, I could've told you that.

Well you know me, Rob, slow on the uptake.

So, tell me what you think you know.

Well, as you may recall,

a young police officer, Tyler Bates,

was murdered outside a pub in Poplar nearly a year ago.

We have reason to believe that the killer

is a serving police officer.

Go on.

Grace Harper, who was the landlady of the pub

where Constable Bates was killed, she saw who did it

and she was prepared to identify the killer,

but then she was murdered too

while she was in police protection.

Her brother-in-law, Harry Steadman, told someone

that the killer would never be caught,

because he had friends in high places.

And then he was murdered.

That is three people dead, Jack.

Three, murdered by a serving police officer.

You have to tell me who that officer is.

Help us put a stop to this.

No, I don't know what you're talking about.

I don't know you anymore.

-This Grace Harper. -Yes.

You said she was killed while she was in police protection?

She was, someone in the force told the killer

where she was hiding out.

It was you.

Wasn't it?

In my experience, it takes a great deal

to persuade someone to turn supergrass,

especially when one such witness has already been killed.

Now if David Bradford

wants anybody to inform on this corrupt officer,

he'd better be offering something totally cast iron

in return.

I guarantee the next informant won't end up dead.

-I'll talk to David. -Yeah.

You do that.

It's gonna be okay.

Wish I could believe you.

-You don't know it was him. -Don't I?

You better do something quick, otherwise I'm dead.

Now that he's seen us together, we both are.
