Aidan!

Where are you?

Aidan!

Aidan?

Are you there?

Aidan?

Aidan? Argh!

I thought something had happened to you!

What are you trying to do to me? I'm sorry. I'm sorry.

What the hell are we doing here?

I wanted to ask you a question. What?

Oh.

Ruth, will you marry me?

I'm serious.

Yes.

Yes, yes!

Yes!

I love you. I love you.

Before I hear any protestations

about who is and who isn't working on this case,

I'm not interested.

It's a big fraud operation and that demands a big response,

so you'll all be involved.

Anyone shirking that responsibility will have me to answer to.

Attention to detail is paramount.

Half the team will be out on the road to take witness statements

and half will go through their bank transactions

to match them to the records of the accused.

That information will need to be carefully collated...

It would be better if those taking statements were responsible for the bank records as well.

By DC Waterhouse A smaller team would be a more efficient one, that's all.

What DC Waterhouse is trying to say is that would be an excellent idea, sir.

Don't try to get out of it, Zailer. This lot did it for the money.

You'll do it because it's your job.

Oh, 'Thank you for trying to help me out there, Charlie'.

'Oh, that's no problem Simon'.

How long will it take your divorce to come through, do you think?

Oh, I don't know.

However long it takes, we've got each other now.

Listen Ruthy...

I've been wanting to tell you something but...

I'm not sure if I can.

What is it?

A long time ago...

A long time ago, I hurt someone.

Well, we've all hurt someone in the past.

I'm sure you didn't mean to.

She died.

Who died? What happened?

Whoa, slow down. It's not what you think.

OK? It's just... You have to trust me, please.

Aidan, what happened? I don't even know if I can talk about it.

Not yet. I will, I promise.

What? What is it?

You have to tell me what it is. I...

Aidan! I... I can't.

Aidan, please, you have to tell me.

She... What?

I can't, Ruth.

I'm sorry. I can't.

All right.

All right. It doesn't matter.

Look at me. It's all right. It's OK.

What do you make of this report?

Fiver says he's shagged her by the end of the week, eh, Sarge?

Don't be pathetic, Sellers.

And change!

Come on, let's go! Let's go!

Come on, let's go!

Come on, more, more!! Punch! Punch!

Come on, push!

Come on! More! More! More!

Oooh! I'm so sorry.

Are you OK?

Did I hurt you? Are you OK? No, it's fine. I'm all right.

Move your jaw, let me see. Oh, God. It's fine.

Listen, you've got to let me buy you a coffee.

It's all right, really.

No, it's the least I can do after dislocating your jaw.

OK, but I'll still get my revenge next week.

I'm sorry to take my stress out on you.

Bit of police brutality?

Is it that obvious I'm a cop?

No, no. One of the other ladies said.

What do you do? I teach. At St Mark's Comprehensive.

OK. Well, that's a kind of policing, isn't it?

Can I ask you a policey kind of question?

Yeah, of course.

If someone had a criminal record, how would you find out?

Well, if it's someone at the school, might be working with the kids...

No, it's nothing like that, no. It's a friend of mine.

Her partner said something about hurting somebody once but didn't say, how, why...

If she's really worried she should go to the police and talk about her suspicions.

I don't think she'd go that far. Ruth, in my experience,

if a man's hurt a woman in the past, he'll usually do so again.

Yeah, actually, I don't think it's that big a deal

but I'll tell her what you said. OK.

Thanks for the coffee.

Hope the jaw's OK. See you next week.

Hi.

Hey. How you doing? Good.

Not at school? I'm on a break.

This thing's in a dreadful state, needs a complete overhaul.

Look, you know what you said the other day about hurting someone?

I can't get it out of my head.

Could you at least tell me who it was?

Ex-girlfriend?

Aidan, please, if you tell me - Mary.

Mary Trelease was her name. Are you happy?

And she was? I thought you said you trusted me?

I do trust you. I have to finish this.

Fine.

See you later.

She said he'd hurt someone before

and it was pretty clear to me she was talking about herself so...

She's worried, I think we should follow it up.

Is this a poorly disguised attempt to get yourself off the fraud case, Zailer?

No, sir. I just think it would be worth somebody checking it out.

Zailer, our job is to investigate crimes that have already been committed,

not to follow up gossip from your pilates class.

Thank you, sir. For your time, your consideration,

your limitless wisdom!

Don't know why I bloody asked, it'll only take five minutes.

What will?

Ruth Blacksmith? Married to Jason Blacksmith.

Who's she?

15 Elm Close. Let's see if he's got any previous.

Aha. Assault.

Against another man, Aidan Harper.

No charges brought.

It was only a few months ago.

I'm going to pay them a visit.

I can come. No. I'll go.

I'm at the dentist.

Hello?

Hello, Ruth?

Ruth?

Victim is Jason Blacksmith, 34 years old,

worked with his wife at St Mark's Comprehensive.

Cause of death? Single stab wound to the neck, sir.

Break-in?

No sign of forced entry. Where's the body?

Straight upstairs. All right?

No gloves, DC Williams. Stay outside, please.

Weapon? Nothing yet.

Apparently not a knife. Could have been scissors.

Maybe picked up from this desk, which suggests...

Wasn't premeditated.

Probably died on Friday so he's been here for a couple of days.

Would have been longer if I hadn't popped in, sir.

You thought your friend was at risk, not him.

She's more of an acquaintance, sir.

He's been dead for several days and she hasn't noticed?

The neighbours say she moved out a few months ago.

They split up in the spring.

She didn't tell you that?

Well, like I said, we're not exactly friends.

Who's this?

That's her. I'd better go down.

Just because she's a mate of yours, Zailer, don't go soft on her.

No, sir.

I know you must be reeling, but I do need to ask you some questions.

Did something happen between you and Jason?

Did you have a fight? An argument that got out of hand?

God, no. Jason would never lay a finger on me.

When did you last see Jason?

Three or four weeks ago.

I came around to talk to him about the divorce.

It was after school.

And when did the separation happen?

Four months ago.

And who initiated it?

Me.

Why was that? Because I met someone else.

Was the name of the man you left Jason for Aidan Harper?

Yes. Jason and Aidan had an argument here, didn't they, a few weeks ago?

No, I don't think so.

Well, they did, because neighbours called police to complain.

Jason hit Aidan. You didn't know that? No.

It was Tuesday the 3rd. You live with Aidan now, yeah?

Yes. And you didn't notice he came home one night having been in a fight?

Look, I don't know what you're talking about, OK?

It's OK. It's OK.

Was it Aidan you were talking about in the car park that day?

No.

But there was some animosity between the two men, yes?

Look, Aidan would never do anything to hurt Jason, all right?

I didn't want to either. I loved him.

OK, OK. You know, we can talk about this later, all right?

Forensics have to take some fingerprints and some other things

but then they'll drive you home, yes?

I'm going to give you my numbers,

home and at work

and I want you to call me if there's anything that's worrying you

or even if you just want to talk.

Thank you.

Can you get cracking on the door-to-door, DC Williams? No problem.

I should bloody hope it's not a problem, cheeky cow.

So she loved Jason so much, she left him three weeks after meeting someone else.

I still think it was Aidan she was talking about in the car park.

If she was lying about that, she could be lying about everything.

You know, it's not a crime to fall in love, Simon.

Great, thanks.

Aidan Harper. No previous.

Mr Aidan Harper? Yeah.

Detective Sergeant Charlie Zailer. This is DC Simon Waterhouse.

We're investigating a murder. Do you live here with Ruth Blacksmith?

Yeah, yeah, I do. Why, has something happened?

Her husband, Jason Blacksmith, was found dead in his house this afternoon.

We need to ask you a few questions. Is it all right if we come in?

Yeah, yeah, of course. Thanks.

So does Ruth know? Yes. We've just spoken to her.

How is she? Is she all right?

She was understandably upset.

Yeah. Where is she?

Someone will bring her home shortly. Did you know Jason Blacksmith?

Er... not really. I met him once, briefly.

When was that?

Couple of weeks ago. Went round to collect some of Ruth's stuff.

The evening of the 3rd?

Yeah, yeah, something like that, could have been.

That was when neighbours phoned to complain about a fight between you.

It... it wasn't a fight.

He was shouting, he'd been drinking.

He took a swing at me. It was nothing, really.

Did you hit him back?

I pushed him, I pushed him off.

Did you tell Ruth about the row?

No. I didn't want to worry her.

Is it true that you told Ruth that you hurt someone once?

She told you that?

Just clarify for me what you mean by 'hurt', sir.

It was... it was nothing.

You're taking this completely out of context

But you did hurt someone?

I was speaking about some friends, it was said in confidence.

It was... It was a metaphor. Where were you last Friday?

Sir. You think I did this?

I had a job in the morning, yeah?

And then I came back here in the afternoon.

In the evening, I was practising for a performance next week.

So you play professionally? No, it's... it's in my old college.

And Ruth was here with you?

No. She was out with some friends, I think, somewhere.

What time did she get back?

I lose track of time when I'm playing.

Sorry, do you mind?

Is there anyone else who can verify your whereabouts?

Er... No.

We need you to report to the station for fingerprinting and DNA processing.

Are you willing to do that, sir?

Yeah, yeah, sure.

Thank you very much.

Ruth joined us seven or eight years ago.

And when the PE vacancy came up, she suggested Jason.

I was a bit concerned about having a husband and wife working together at first.

You know, relationships in the work place. Not usually a good idea. No.

No. Actually, it worked well.

Until a few months ago, when this guy Aidan turned up.

Did you meet him? Only that once,

when he came to the school to tune the pianos.

What did you think of him? He did a good job, didn't say much.

But Ruth was knocked for six by him.

At first it was all about what a musical genius she'd uncovered,

and then... she just fell head over heels.

And then she left Jason?

Within weeks.

Everyone was completely shocked.

Her and Jason had seemed perfectly happy.

How did he take it? The poor bloke was completely broken-hearted.

And of course, seeing her every day was crucifying him.

It became clear he was drinking heavily. I had to sign him off, eventually.

When was that? Two months ago.

Seemed unfair, to be honest, he should be the one to lose his job

but I have to think of the children first and foremost.

And Ruth, how did this affect her?

Just the opposite. Couldn't hide her happiness, like, euphoria.

She was completely and utterly besotted.

Love that is not madness is not love.

What?

It's a quotation.

Don't get it.

It means, it's not logical, is it, who we are attracted to.

I mean, haven't you found that?

Sorry, why is this relevant?

Well, we're looking for a motive here.

I think evidence would be more useful.

Oh, thanks for the advice!

Hey. You OK?

I can't believe he's not here any more.

I'm so sorry, Ruth.

He was a good person, you know. He was kind. Yeah.

What have I done to him? Stop it. You can't blame yourself.

I destroyed his life. Please. Come here. No. I need to be on my own.

There's someone upstairs to see you, Sergeant.

Santa Claus, Archbishop of Canterbury, Attila the Hun?

It's the sister of Jason Blacksmith.

The sister of Jason Blacksmith to see you, Sergeant.

I introduced them. Ruth was my friend first.

I said, 'You should meet my brother'.

Wish I never bloody had now. When was that?

Over ten years ago.

Ruth was like one of the family.

Then suddenly out of the blue, she met this new bloke,

turned her back on Jason and walked away.

Do you think Jason wanted to get Ruth back?

He was obsessed with it.

I said to him, 'If she can do this to you after all these years, she's not worth it'.

He couldn't see it.

He kept phoning her.

Was Jason seeing anyone else, as far as you know?

No. It was all about her.

No-one else in his life he might have had a problem with?

The only person he had a problem with was Ruth's new bloke.

He hated him.

I understand you were there the night Aidan came around to see Jason.

Can you tell me what happened?

Aidan turned up,

started saying some vicious things,

taunting him,

saying Jason meant nothing to Ruth now.

It was almost like he wanted Jason to hit him.

Of course, eventually he did.

Had Jason been drinking?

He'd had a few. He didn't used to drink

and I never knew him hit anyone before.

He just made him see red.

And did Aidan hit him back?

No. He ran off. I thought at the time, he'll be back.

Morning. Hiya.

Look, I'm sorry about last night. I wasn't thinking straight.

It's fine, he was your husband, you were upset.

Do you have to rush off? Can't you stay for a cuppa?

When the police came asking questions,

they said you told them I'd hurt someone. Oh, God no.

Something I've never told anyone before, you told the police?

No, no, look, I met her at the gym and it was long before any of this happened, OK?

I didn't say it was about us or you.

I said I was asking on behalf of a friend.

Look, you can't say something like that and expect it to have no impact.

I was worried.

Who is this woman Mary?

I thought you said you trusted me.

I do trust you. Christ, Aidan, look what I've given up for you!

Yeah, wonderful Jason. You made that quite clear.

What?

I have to go to work.

Right, so Ruth's fingerprints are all over the house

but that's not really surprising, she's lived there the last five years.

Also, Jason's sister and two other sets as yet unaccounted for

neither of them matching Aidan Harper's.

Sellars, what have you got?

Jason's computer shows nothing unusual.

Bit of football, bit of porn.

All very soft stuff. Nothing I'd call out of the ordinary.

And his phone?

In the last month, he called Ruth 64 times

but she usually didn't answer. Neighbours?

I got nothing from the door-to-door.

Nobody saw or heard anything on the day.

In fact, none of them have seen much of Jason at all recently.

I'm sorry, nothing? You've got nothing to tell us?

Well, I can't just invent evidence when there isn't any.

What do you expect me to do? I expect you to go to every house.

Did you go to every house on the street?

Well, some people weren't in and I haven't had a chance to go back today yet.

You'd better get back there.

I think we'd all be grateful when you start doing your fucking job, DC Williams.

Anything from Aidan?

Both parents deceased.

He studied at the Guildhall School of Music in London from 2001-2003

but failed to graduate. He's been trading as a piano tuner and restorer since 2006.

I spoke to most of his clients,

they only see him a couple of times a year, they don't know much about him.

Thank you very much. That's great.

OK, come on, everybody, someone must know something about this bloke.

Sergeant Zailer? I'm Professor Fox.

This is DC Waterhouse. Thanks for seeing us.

I'm afraid I only have a few minutes between classes.

I understand you want to talk about Aidan Harper?

Yes. He's due to play here in a few days, is that right?

He'll be playing in front of a panel of tutors to see if he can be readmitted as a mature student.

Do you remember him when he was a student here originally?

Of course. He was exceptionally gifted.

I had very high hopes for him.

Yet he didn't complete the course, why was that?

Well, he was due to play in a final year concert,

his debut, if you like, as a professional soloist.

Been practising for months.

A few days beforehand, he just didn't turn up at college.

That was it, I haven't seen him since.

What happened to him? I presume his nerves got to him.

Being a soloist is not just about talent, it's about temperament.

It was a great disappointment to me that Aidan couldn't control his emotions.

So how did this audition come about?

A friend of his came to see me, Ruth... Blacksmith.

Mm. A few weeks ago. She brought me a disc of him playing.

It was good.

She clearly has ambitions for him to resume his career.

And what are his chances?

We shall see.

This is where he'll be playing, if he can handle the pressure.

If he does, and he plays well,

then, maybe there can be a future for him. Maybe.

I just love the German romantics, don't you? That's Russian.

Min! Thank you. From the beginning.

Professor Fox was all heart, wasn't she?

Full of sympathy and understanding.

What?

This morning?

She's not pulling her weight, Simon, she deserved it.

It's not like you.

Hi.

I wasn't sure you'd be in today.

Gives me something to do.

Well, this isn't a formal visit.

I was just dropping by to see how you're doing.

As a friend.

As a friend?

Thanks.

We went to see Professor Fox today.

She said you'd been to see her,

hoping to get Aidan's career back on track.

Yes, well, he's a wonderful talent and it was just going to waste.

Why did he drop out of college,

why did he stop playing the piano for all those years?

Well, I think they were tough on him.

He needs encouragement, support,

someone who believes in him.

Do you still have a key for Jason's house?

Yes. It's still half my house.

Does Aidan know where it is? Aidan did not kill Jason, OK?

Ruth, I know how much you love him.

But you've only known him for six months.

All I'm asking, please, is don't keep anything back from us

because if you are and we find out you're covering for him, you're going to be in deep shit.

I think you should go.

She's standing by her man but he's still our number one, sir.

OK. Team all right? Yeah, they're good.

Because if it's not it's down to you, understand?

I don't want you coming whining to me about weak links.

I'm not whining. Women working together.

Cats in a bag, if you ask me, always someone's time of the month.

Sir, if you're implying - I'm not implying anything, Zailer,

I'm telling you straight. No more handbags, OK?

Thank you, sir

Have some cake, sarge! No, thanks.

Have you got that path report back from the lab?

Oh, yeah. Here you go.

It's time of death, some time Friday night between 10pm and 1am.

His blood alcohol's through the roof. 197.

Equivalent to ten pints of lager or six pints and four doubles

or two bottles of wine. Yeah, all right, we've got the picture.

He drank at the George pub on Bank Street.

Owner says he was in Friday night and he's checking his CCTV now.

I'll come with you.

Watch him Sarge, two ginger beers and he's anybody's!

Do you know who I'm talking about when I say Jason Blacksmith?

Yeah, yeah. Did he come in here often?

He used to come in two or three times a week but recently it was nearly every night.

He used to sit at that table in the corner.

Right.

Did he come with friends or talk to other customers?

It was mostly about the beer, to be honest.

I had to take his car keys off him a couple of times.

So you were friendly with him? I wouldn't go that far.

Although he did tell me that his wife wanted a divorce and that he was going to fight it.

Did you speak to him on Friday night?

Just said hello.

And was he chatting to anyone else at all?

We were really busy, I'm afraid, we had a hen party in. Mayhem.

Do you know the name Aidan Harper?

Doesn't ring a bell.

Sorry, no.

Why, is he your prime suspect?

Very good. No, he's just helping us with...

With your enquiries. Yeah.

I've got Jason on camera, if you want to have a look.

Great.

Thank you. After you.

OK, here he is arriving at 9.37.

This is the only camera you've got, the one on the door?

Yeah, that's it.

And... there he is leaving again at 11.03.

There are your hens.

Again.

OK, no sign of Aidan. No.

I need to take this with us, is that OK?

Yeah, of course. Be my guest. Thank you.

Aidan!

Here you go, come on.

Come on! Come and have a drink.

Oh, come on, vinegar tits, loosen up for once, eh! Come on!

Happy Birthday, Colin.

We're off down The Anglers, Sarge, you coming?

Er... Yeah, I'll catch you up.

Come on, Sellers! All right, Willy! I'm coming!

Hi. Hi.

Is this the Blacksmith murder? Yeah.

That's the stuff we're still working on

and those are the prints we've already matched so help yourself.

Great.

Excuse me. Could you confirm this is correct?

I need to be 100% sure.

Yes, yes, it has been checked and double checked.

I can assure you, it is correct.

Yeah. It's me.

I think I've got something.

Ruth. What are you doing?

You lied to me.

Let me in and I'll - You lied to me!

Let me in! No!

Open the door, Ruth! Go away!

Ruth, you have to let me in!

He's trying to get in!

Who? Aidan. He's around the back.

Ruth, Ruth, Ruth!

I'm arresting you on suspicion of the murder of your husband, Jason Blacksmith.

All right, let's go.

This is Ruth Blacksmith.

She has been arrested on suspicion of the murder of her estranged husband, Jason Blacksmith.

She has been brought straight here from her current address for questioning.

Now I've issued you with a caution,

I'm going to search you. Are you carrying anything that may hurt me?

Address?

Date of birth?

We should let her stew overnight.

Buy herself some time.

No. If we go in hard now,

we'll get a confession.

Are you OK?

I'm fine.

Yep?

Great.

Brief's here.

You remember the last time we spoke, what I said to you?

I told you to tell the truth, didn't I?

And that if you didn't, it would be very bad for you.

Did you understand what I meant when I said that?

Yes. Right.

For the benefit of the tape, I am now showing the witness exhibit number CZ08.

Do you know what that is?

No. This is a letter to Jason

from his solicitor about the divorce.

Have you seen it before?

I don't remember.

You don't remember?

It's got your fingerprints on it.

It's dated the day before Jason died.

He would've received this letter the day he was murdered.

We know you were in the house that day, Ruth.

But you told us you hadn't seen him for three or four weeks.

You lied to us, didn't you?

Didn't you?

Why did you go round?

My stuff was there.

And what happened?

When I got there, he was in a really bad way.

He was talking about suicide.

And I felt really guilty about what I'd done to him.

And then I...

I know I shouldn't have, but...

What?

I couldn't bear to see him like that.

I still loved him.

So I er...

I gave him a hug and...

You had sex with him?

I'd been with him for 10 years, for God's sake.

But then I was terrified Aidan would find out.

He was...

jealous of Jason, scared that I'd get back with him.

Had this happened before? No.

No, never.

When I met Aidan, it was erm...

That was it.

We had to be together.

But I hated myself for what I'd done to Jason.

So, what happened after you had sex?

He thought I'd changed my mind.

That we were gonna get back together.

It was like leaving him all over again.

He was sobbing and it was awful.

That was the last time I saw him.

Jason threatened to tell Aidan, didn't he?

That you'd slept together. No.

Is that why you killed him, to stop Aidan finding out?

I didn't kill him. Heat of the moment? No!

OK. That's enough for today.

Interview terminated at midnight 15.

Start again tomorrow.

Just cos she slept with him doesn't mean she didn't kill him.

I know!

Just go home, get some rest.

Morning, darling. Fuck off, Sellers!

Zailer, what's going on?

Yesterday it was all about the bloke, now you've arrested the girl. Is she guilty?

She says that she went to the house the day that he died, but they had sex and then she left.

Sex with the ex, eh?

Can't make up her mind, can she? What does Waterhouse think?

I don't know, sir. I'll ask him when he gets in.

Good copper, Waterhouse. Don't take him for granted.

No. I'll bear that in mind. Well, we can't hold this woman for ever.

Why aren't you in there now?

Because I'm talking to you, sir.

Looks like it's you and me, Sellers.

Did you get some sleep? Not really.

OK, Ruth. I...

I really need you to start helping me.

And you really need to help yourself.

That day at the gym when you told me about a friend

who'd mentioned a partner who'd hurt someone.

I've spoken to Aidan, and I know you were talking about him.

He said he'd hurt someone a long time ago and that she had died.

It was like he needed to get it off his chest.

But then he wouldn't say any more about it.

Eventually, I got a name out of him.

Mary Trelease.

And who was that?

It didn't mean anything to me.

But then, last night, I followed him into town.

And I saw him with another woman.

I couldn't believe it.

I got back and...

I went through his stuff and I found... a photograph.

For the tape, I'm showing the suspect a photograph that was in her possession when she was arrested.

DC Sellers?

No, it's not that one.

The one at... I'm sorry.

Was it this photo? It says Mary on the back.

Yes. And you think this is Mary Trelease?

Well, I... I don't know.

But if it is, she's very much alive. I saw her with my own eyes.

And this is why you were arguing with Aidan when we arrived last night? Yes.

Everything he's told me has been a lie.

What's going on?

I thought we were going to interview Ruth.

Just did. You weren't around. I was in the evidence room. Why didn't you call me?

Sorry, Simon. I've got a murder to solve.

Where's Ruth? She's all right. She's at the station.

So it's your recital at the college tomorrow.

Is that right? How's it going?

You can't really think Ruth did this, can you?

She's not capable of killing someone.

Ruth has admitted to us that she was at Jason's house the day he was murdered. What?

And they had sex.

I don't believe you. She admitted it to us under caution.

Ruth also told us that she saw you last night with another woman.

And that woman is Mary Trelease. Is that true?

Yeah. She's my... sister, my stepsister.

That's not the impression Ruth got.

Well, it's the truth.

That's what I was trying to explain to her last night.

So, you told Ruth that you hurt this person?

And that she died? And now she's very much alive?

She made assumptions that she shouldn't have.

I would... never... hurt my sister.

Never. You can ask her yourself.

We intend to.

We're gonna need her address, telephone numbers and place of work.

Fine.

I'll wait outside.

He's hiding something.

It was clearly news to him that Ruth slept with Jason.

Doesn't rule him out. I still think he's deeply jealous of Jason.

Why are you dreaming up theories and trying to make facts fit?

Focus on evidence.

We're gonna have to let Ruth go.

Human beings have things called emotions, Simon. Ring any bells (?)

Ruth? We're releasing you on bail, pending further investigation.

Thank God.

And I should also tell you that we went to talk to Aidan this morning.

You told him.

I've really fucked everything up, haven't I?

But I can tell you that he claims that the woman you saw him with, Mary Trelease...

is his stepsister.

Well, why wouldn't he... tell me he has a sister?

What HAS he told you about his family, Ruth?

Both his parents are dead.

I thought he was an only child.

There's a lot you don't know about Aidan, isn't there?

While you're both under investigation,

I suggest that you do not go back to Aidan's house.

But I have to speak to him.

It's for your own safety, Ruth.

She's ready to go. OK.

Hi. Has anything you told me been true?

I was going to explain about Mary. I don't know who you are any more.

What about you, Ruth?

You swore there was nothing left between you and Jason.

Did you kill him? What?!

How can you even ask me that?

I think you'd better leave.

Aidan, please!

Mary Trelease? Hello.

Detective Sergeant Charlie Zailer. Thank you for meeting me.

Er... do you want a cup of tea or anything? No, thank you.

Do you know why I'm here? Aidan told me

all about the murder last night.

Right. He said he thought that you suspected him.

But you just... have to know it couldn't have been Aidan.

He's the most gentle and artistic soul.

OK.

So you were with him last night. Where did you go?

We met up for a drink on the South Bank to help get his mind off it all.

Have you met his girlfriend, Ruth Blacksmith?

Yeah, he's mentioned her, but we've... we've never met.

OK.

He hasn't mentioned to her that he has a stepsister.

Which is... unusual.

Have you any idea why that might be?

They'd... they'd only been going out a few months. I don't know.

Ruth also said that he says that he... hurt you and...

and that you were dead.

Can you think why he would say that?

God. Look. Aidan has...

a tendency to... overdramatise things.

We have a complicated history. What does that mean?

My mother was a single parent.

When I was eight, she met Aidan's father.

His mother had died when he was little, and we became a family, of sorts.

You might call it dysfunctional. Dysfunctional?

My mother was an alcoholic. And when she'd drink, she'd become violent.

Er... Aidan was always protecting me from her.

But it meant that he bore the brunt of her... abuse.

Er... and then when she died,

I think he just wanted to put his whole past behind him.

And that involved cutting ties with me, which... which was painful.

We haven't had much contact until recently.

Recently? So... what happened? What changed?

Well, I think... I think having Ruth in his life made a big difference.

Made him happy again.

I know how you feel about the importance of motive over evidence.

But I still think Aidan's our man.

Even his stepsister, Mary, says they've been estranged

for the past 10 years, but recently they've been building bridges.

And that's all thanks to Ruth's influence.

So everything, his whole stability - his music,

his professional rehabilitation, even his relationships, all thanks to Ruth.

Now, if that's threatened by Jason trying to get her back...

I reckon that would be enough to push him over the edge. Don't you?

Sorry.

Can I have a word with you, DC Waterhouse?

What are you doing with that girl?

We're looking into break-ins and aggravated burglaries in the area.

Amber thought it would be a good idea - Are you sleeping with her?

What? I don't care if you are. It doesn't matter to me! It's just... it's affecting your work.

You're distracted, unsupportive. You're not even listening to me!

I'm trying to hold the team together and you're being totally unprofessional!

I think you're the one being unprofessional.

What about you and this business with Sellers?

That was a dare. That was a joke at an office party!

I'm not talking about that.

I'm talking about you taking him into an interview completely unprepped.

Because you were too busy chatting up Little Miss Sunshine!

You know something? I think you're losing it. You're completely losing the plot.

You are becoming impossible to work with!

I'm not gonna listen to this conversation.

And another thing.

Go fuck yourself!

Morning. Morning.

You OK?

Yeah, I just...

couldn't sleep.

What time is it?

Um...

Just before six. We should probably get off.

Yeah. Gotta get some clean clothes.

Yeah, whatever you need to do. I probably should do that.

Do you want tea or coffee or anything?

Oh, shit. There's no milk. No, I'm fine, I'm fine.

I don't think we should rush into - No.

Definitely not.

I'm gonna go. Yep.

"Hi. I can't take your call at the moment. Please leave a message."

How are you doing? Yeah, I'm at the station.

Yeah. No.

Right. I'm on my way. Yep.

Got it.

Thanks for that, Amber. Great work. And nice top.

Oi, Willie!

Nice top (!) Shut up, Sellers.

This is the house where Aidan and Mary grew up.

When you said the mother died 10 years ago,

I realised it's the same time Aidan suddenly left college

and stopped playing the piano.

So I looked for death certificates for a Trelease.

It's not a common name, so it wasn't hard to find. Here she is.

Mary Trelease? Same name as her daughter.

So when Aidan said he hurt someone and she died, he was...

Talking about his stepmother.

I've been talking to Mr and Mrs Nesbitt next-door.

They remember the family vividly. The father was always away on business.

The mother was a heavy drinker, just like Mary said.

They said they felt sorry for the kids, having to put up with her.

On the day she died, the first the Nesbitts heard about it

was that Aidan turns up on their doorstep in the middle of the afternoon.

He's in a bad way, says his mother has fallen down the stairs.

Mrs Nesbitt phones for an ambulance.

While Mr comes back over here with Aidan.

OK. So Mr Nesbitt finds the mother lying at the foot of the stairs.

She's got a cushion underneath her head.

Now, Mary is trying to resuscitate her.

Mr Nesbitt got down and tried to give her mouth to mouth, but... it was no good.

None of that is in the coroner's report.

So what you're saying is, did she fall...

or was she pushed?

Yeah. What was mentioned in the coroner's report

is she had a high level of alcohol in her bloodstream, liver damage and pleurisy.

They conclude death from heart failure following trauma.

So, after she fell, or was pushed,

she landed...

here. Yep. Right. OK.

So, I'm Aidan, this is mother.

She's unconscious - And drunk. I reach for a cushion to put under her head.

But before I put it under her head...

I put it over her face.

Which is understandable. She's been making your life a misery for years.

Maybe it wasn't just Aidan.

Maybe they were in it together. Mary was here all the time.

So, when Aidan went to get help, he left Mary alone in the house with the mother.

Yeah.

But Mary didn't see fit to mention any of this.

Sellers?

Mary? I'm Ruth. I'm Aidan's girlfriend.

Oh, hi.

Can I speak to you?

Anything? I reviewed the door to door witness statements, and no matches.

Good work. Keep trying. It's all set up and ready, Sarge.

Zailer. Get in here! I will, sir. Please, excuse me one minute.

OK. So...23:03.

This is Jason leaving.

Can you slow it down?

Stop! Back a few frames there.

Zailer, what's going on? It's the CCTV, sir.

From the pub, the night Jason was killed.

Forward again slowly.

Freeze!

We need to find her.

Thanks.

Sorry for turning up like this. That's OK.

I can't believe Aidan didn't mention he had a sister.

That we haven't met before. He's told me a lot about you.

Really? Sugar? No, thanks.

Yes.

I'm sorry about your husband.

Thank you.

You know the... police still think it was Aidan?

He told me. Is that what you think? No.

No.

I wanted to ask you um...

Well, Aidan had... said something about hurting you.

I'm just trying to make sense of it. Aidan would never do anything to hurt me.

No. No, I didn't think so.

We've always looked out for each other.

You know he has his performance today?

Performance? Mm. At his college. Didn't he tell you?

I expect he wanted to surprise me. He knows how nervous I get on his behalf.

He's been practicing for weeks.

But... everything that's going on, I don't think he'll manage it.

Are you going to watch him? I'd like to be there to support him.

Don't think he wants to see me right now.

I understand.

You're worried about whether or not you can trust Aidan, aren't you, Ruth?

I do trust him.

That's not the question, though, is it?

Sorry? The question is, can Aidan trust you?

We don't know Mary killed him.

All we know is she and Jason left the pub at the same time.

Yeah. And three hours later, he's dead. OK.

We have her arriving five minutes before he did.

She knew who he was, she followed him, chatted him up.

There's no sign of forced entry at the house, so she must've been let in.

Do you think he was chatting up some random bird, or did she say who she was?

Maybe Aidan was there at the house waiting for 'em.

He had access to a key. We have absolutely no evidence putting Aidan at that house.

Don't get me wrong. Aidan really thought he was in love.

He fell for you in a big way. Yes, well, I fell for him too.

It was very - And so, of course, it was only natural that I wondered what you were like,

what made you so very special to him.

And so I came to look for you.

What? I saw you at the school. I could see that you were very pretty.

You saw me at school? But Aidan's not just interested in looks.

You were watching me. I wanted to know what you were like as a person, a woman, a partner.

Oh, my God. And the man you'd married, whether Jason was anything like Aidan.

Jason. Funnily enough, I had this idea

that Jason might be more like me. And he was, in a way.

You spoke to Jason? I really felt for him.

The pain that he must've felt when you walked out on him.

When the person that you've dedicated your life to abandons you for someone else.

We got on well at first.

But then...

all evening, all he talked about was how much he hated Aidan for stealing you.

He got drunker and drunker and...

he was showing me all these photographs of you on the computer.

And he said that he wanted to kill Aidan.

To kill him. My Aidan.

And he said that you'd been around there

and you'd spent the afternoon in bed with him.

You betrayed Aidan. Good to meet you.

You stole Aidan away from me and then you betrayed him.

I have to go now.

Goodbye, Ruth.

Anything? No.

Mary?

Mary Trelease!

No sign of her.

Still warm. She's not long gone.

She's pretty fond of her brother.

Run a check on the car.

And call the hospital. See if she's due at work today.

Come and look at this!

Mm. Yeah.

Look at this one.

Bit more than a brother sister relationship.

Yeah. I mean, they're not blood relatives, but you're right. And look.

Two lonely kids, thrown together into this new family.

With a violent, alcoholic mother and a... absent father.

'He protected me,' she said. Huh!

And in return, she worshipped him.

He's good-looking, talented. The only person in the world she can trust.

There's no recent photos. Maybe Aidan put an end to it.

And Mary couldn't let go.

Ruth comes on the scene,

Aidan falls head over heels. Mary gets jealous.

Yeah.

He didn't even mention... Mary to Ruth.

She's been relegated to... guilty secret.

But why would she go after Jason?

Yeah. If she's in love with Aidan, she'd want to get rid of Ruth.

Maybe Jason was getting in the way of Aidan's happiness. No.

Maybe... she'd do anything to keep him happy. No.

She wants him for herself.

This is an obsession.

Yep. OK.

She's not at the hospital. Didn't turn up for her shift.

Simon, that's Ruth's car.

Charlie? Blood.

Shit!

Shit, shit, shit!

Pick up, Ruth!

Come on. Pick it up! Mary'll be with Aidan. Let's go!

Stairs!

There she is.

Mary! Mary!

Mary, wait!

Mary! Where's Ruth?

What have you done with her?

What are you talking about? What's happened to Ruth?

I don't know. Mary's never met Ruth.

You're covering for her again. That's not true.

Just like when she killed your stepmother. No, it...

It was my fault. It was an accident.

I pushed her away and she fell.

We know she was smothered. Did you smother her?

What? No! When you went for help, she was still alive. Think about it!

I think so.

Tell him what happened when you were alone with your mother, Mary.

I didn't kill her.

What about Jason? How did you kill him?

You were with him the night he was murdered, weren't you?

No! We have you on camera.

Your DNA and fingerprints are all over that house, aren't they? Am I right?

Mary. What have you done?

He said he was gonna kill you. I was trying to protect you.

Oh, my God! Is that why you killed your mother? To protect Aidan?

Mary, no! Well, she... she hated you!

You let me think it was me! Why didn't you tell me?!

I just thought you wouldn't love me.

We're not kids any more, Mary. You know I can't love you like that.

We know you saw Ruth today.

We found her car.

She's bleeding, isn't she?

Mary. Have you done something to Ruth?

Please help us. Just tell us where we can find her.

Have you hurt her?! Charlie!

Ow!

Mary! Mary, where's Ruth?

Please! Please tell me where Ruth is.

Did you bring her with you? Is she here?

Is she still alive?

- I love you. - Mary! No, Mary!

No.

Ruth. We need to find her keys.

Urgent assistance required.

Ruth!

Ruth!

Where's your phone? Left pocket.

Ruth!

Ruth! Shhh!

I can hear it.

I can hear it. This way.

It's somewhere here.

It's this one.

Ruth! She's alive.

Ruth, if you can hear me, squeeze my hand.

I need an ambulance immediately.

The ambulance is coming. Stay with me.

Stay with me. You're gonna be all right.

You're gonna be all right.

You're gonna be all right. Stay with me. Don't go. Don't leave me.

On the left.

I'm here, Ruth.

They reckon Ruth's gonna be OK.

How did you get that coffee?

I know the right people.

Thanks.

We make a pretty good team.

Yeah, well. You know what happens in Vegas stays in Vegas.

What?

Last night.

I was talking about... this.

The job.

No. Yeah. Course. Yeah.

Are you bleeding?

Let's get you to Casualty. No, it's fine.

I've gotta sort out this mess with City Police.

Can you wrap up here? Yeah. No problem.
