[ Down-tempo music playing ] MAN ON RADIO: Control to all units.

Serious assault.

Pencross College.

Victim identified as Abigail Lincoln.

Ambulance in attendance.

[ Music continues ] The victim's name is Abigail Lincoln.

She's the college art teacher.

She was found this morning -- very early, serious head injuries -- by a guy called Harry Webster.

Uh-huh.

He's the guy who made the 999 phone call.

He also administered first aid.

He is the college maintenance guy.

This place is undergoing, uh, a renovation.

No weapon as yet, uh, but we have found his toolbox.

We've shipped Mr. Webster off to the station to get his clothing forensicated for elimination.

Glad to see that you haven't forgotten how to do the job.

WESTON: This is the head teacher of the college, um, Rory... -Rory O'Hanlon.

-Rory, hi.

Martha Bellamy.

I'm the, uh, detective inspector on this.

There's so much blood.

WESTON: We'll get this place cleaned up as quickly as possible.

RORY: How is Abigail?

Uh, the situation is serious, but she's at the hospital.

She's actually in surgery.

We're gonna keep everybody posted.

Obviously we have an exit point, possible entrance point here.

This door here was locked?

That door -- Yes, it's locked.

It leads out onto another corridor.

WESTON: Okay.

Have you got CCTV on that?

RORY: Unfortunately, none of it's actually operational at the moment.

Not while there's construction work going on.

Except for the main gate, of course.

People coming to and from the college.

-Okay.

What about keys?

-Yes.

Can you open up for us soon as we're...

Anyone else hold keys for those?

Harry Webster.

All right.

Nice guy?

Yeah.

Uh, Abigail... she came to me yesterday.

She reported Harry being abusive towards her -- verbally abusive towards her.

-WESTON: Physically?

-No.

What did you do about it?

Well, I felt like I had no option but to -- to fire him.

I told him that he could finish out the rest of his week here.

You have to understand that Harry was convicted of manslaughter, a crime of passion.

He found his wife in bed with another man.

-He served his time.

-WESTON: But, Mr. O'Hanlon -- Mr. O'Hanlon, you have to appreciate that from our point of view, that puts him right in the frame.

[ Down-tempo music plays ] This is, um, uh, Liz -- Liz -- Liz Maitland.

She's the lesbian partner.

If we can get you down to the hospital.

-I'll take her.

-Are you sure?

-Yeah.

Absolutely.

-That would be great.

LIZ: [ Sobs ] -Boss.

Sarge.

-Charlie.

Did I hear the name Abigail Lincoln on the radio -as the victim?

-Yeah.

She made a harassment claim against someone who works here at the college.

She accused him of stalking her.

Abigail came into the station a couple of weeks ago complaining of constant silent phone calls, abusive text messages.

Right.

Did you manage to identify a suspect?

She accused the handyman who worked here, a guy called Harry Webster, so I've spoken to him.

Oh, hello.

-What?

-Oh.

Harry Webster made the 999 phone call.

Okay, Charlie.

Why was Abigail so convinced that it was this handyman guy?

She found out that he had served eight years for manslaughter.

She didn't think someone with such a serious conviction should be working around the kids.

She made her views very clear, and obviously they clashed on that.

BELLAMY: I've got Harry down at the station, so find out his movements the last 24 hours.

[ Down-tempo music plays ] -There's the CCTV down here.

-Yep.

Excuse me.

BELLAMY: Yes.

Hello.

Sorry.

Hi.

You're the police, right?

Uh, that's right.

Yes.

What's happened to Abi?

Is she okay?

-Are you a student, my love?

-Yes.

I'm sorry.

What was your name?

Melissa.

Melissa Parker.

-So if you'll just pop inside.

-Yeah.

I mean, she seems like she's a very popular teacher.

Everybody's obviously wishing her well in her recovery.

Have you been aware of anything going on with Abigail?

Um, well, a little.

There's been some messages going 'round.

Um... What type of messages?

She has a blog online.

Uh, I think she's been getting a lot of abuse from it.

It's not very nice comments.

People have been writing some nasty stuff.

There was a text message that went 'round.

Do you have a copy of that text message?

Yeah, I do, actually.

Okay.

Listen.

My colleague's gonna get all these details.

I appreciate your help with this.

Thank you, Jack.

Yeah.

-Can you open it up and show me?

-Yeah.

Of course.

I don't like touching...

I don't know who sent it, but everybody's talking about it.

-Everyone seems to know.

-Okay.

Have you received anything else from this sender?

-No.

Just that.

-Let me just get a quick copy.

And then I'll take your address, telephone number, and details in case I need to get in touch with you.

You don't know who did this, do you?

She's gonna be okay?

I can't go into any detail at the moment, unfortunately.

Okay.

[ Down-tempo music plays ] [ Door opens, closes ] Right, Harry.

Why don't you tell me your version of what happened this morning?

I've already been through this.

Go through it again.

Went to the art room to collect my toolbox.

Found Abigail.

Called 999.

Tried to resuscitate her with first aid.

Hence all the blood on your clothes 'cause you were trying to help.

So take me through your relationship with Abigail Lincoln if it's -- We didn't have much of a relationship.

Didn't really get on that well.

Mm.

Why is that?

I had a bit of a problem with her -- you know, her and her girlfriend.

Why?

I just don't really agree with that type of thing.

What type of thing?

You know, like two guys or two girls together.

Homosexuality, you think, is a problem.

Precisely.

You had an issue with Abigail's sexuality.

That's why we just tended to avoid each other.

Have you got a mobile phone, Harry?

Yeah.

Everyone's got a mobile phone.

I'm asking because the number that you gave me when I spoke to you three weeks ago has been disconnected.

So do you have a new mobile phone?

Mm-hmm.

I got a new one.

I lost the other one, so I bought a pay-as-you-go.

So since the last time that we spoke, there have been some new comments on her blog posts along the same vein as the others.

So why don't we talk about that?

-Have you seen them?

-Yes.

-Did you write them?

-No.

But you've been on there and you've had a look?

Some of them were quite funny.

Funny?

Some of them, yeah.

That's interesting, 'cause I'd call them vile and obscene.

Elizabeth Maitland made an allegation of criminal damage relating to an incident last night in which Abigail Lincoln's car door was kicked with such force that it left a boot print.

You very helpfully gave us your clothes this morning in relation -to Abigail Lincoln's assault... -Look.

Before you go on -- ...amongst which were your boots, the tread mark of which match the print in Abigail Lincoln's car door.

So you left your boot -- Do you know how long I've been trying to get a job 'round here?

Just when things started to work out, and then she fucking gets me sacked.

I'm going to arrest you for criminal damage and harassment.

You do not have to say anything, though it may harm your defense if you do not mention when questioned something which you later rely on in court.

-Anything you do say -- -Then arrest me.

I just did.

Do you understand?

Oh, this is shite.

Do you understand?

Yes.

[ Mid-tempo music playing ] WESTON: I know I made a mistake.

Thanks a million for taking me back.

Eyes are on you, Jack, all right?

I want you to know I-I'm ready to go.

I've moved on from it if you have.

Last chance, I guess.

But I'm damn glad you're back.

Thanks, boss.

Did you miss me?

Just don't fuck it up, all right?

The doctors have said that they've had to put Abigail Lincoln into an induced coma, so things are not looking good for her.

Her partner, Liz, who's also a teacher at the college, is at the hospital with her now.

Listen.

I was able to trace those text messages -- the ones that were sent to all the college students, the ones with the link to the abusive blog.

I traced it to an unregistered pay-as-you-go.

That same pay-as-you-go phone was the one that made all those silent phone calls that terrorized Abigail two weeks ago.

I wanted to run a cell site on that phone three weeks ago.

If we had more than a fiver to run each investigation, I would've done.

Well, your budget just got a bit bigger, didn't it, Charlie?

So... [ Indistinct conversations ] Can you join me on the roof, please?

-Yeah.

-Yeah?

Thanks.

[ Exhales deeply ] Right.

Let's get this over and done with.

I'm very sorry how everything worked out at the end of the Shaffer case.

It's my job to tell you as your detective sergeant, as your friend, just that now that I'm back, I'm gonna make you my number-one priority.

Listen.

I know you're feeling responsible.

I know that you are feeling guilty for what's happened.

It's not your fault.

Okay?

You're a fucking great cop.

And you've done the best job you can with the time available, the resources available, and, most importantly, the fucking budget, Charlie -- I appreciate you trying to make me feel better, but, frankly, I made the wrong call.

That's what this comes down to.

I should have kicked it upstairs.

I made the decision not to pursue the cell site.

Budgets, whatever.

Fuck it.

It doesn't make a difference.

Because of what I did, Abigail is lying in hospital.

She might die.

I made the wrong decision.

You're the type of detective who always thinks that you're the first one to ever have made a mistake.

And we've all made wrong decisions in our time, but it's what you do to correct that wrong decision that -- that counts.

-You know -- -BELLAMY: Guys.

-Yeah.

-Guys.

Listen, team.

Cell site's back on the phone.

Charlie, this one's for you.

Our stalker is not Harry.

So our cell-site results bring us to that phone, used by this young lad here.

I don't know.

A student or something?

Definite -- Yeah, he must be.

Why don't I take that to Rory O'Hanlon, see if he recognizes him as a student?

-Good idea.

-Yeah.

[ Mid-tempo music plays ] Mr. O'Hanlon?

Quick question.

Um, this is a CCTV image from outside the front gate.

Do you recognize this kid?

RORY: It's Dylan.

That's my stepson.

Dylan.

I don't understand.

Why do you want to talk to Dylan?

There's got to be some sort of misunderstanding.

Dylan isn't a violent kid.

He's got no reason to stalk Abigail.

-It doesn't make sense.

-What kind of kid is Dylan?

He spends a lot of time in his room.

-Don't most kids?

-Where's his mum?

She died 10 years ago.

Committed suicide.

Sorry to hear that.

He's a good kid.

He's an excellent kid.

WOMAN: Sarge?

Yeah?

You've got something?

Yeah.

Come check it out.

Mr. O'Hanlon, you stay here.

We have a few more questions we need to ask you.

Phone, Charlie?

Yeah.

Good.

Turns out there's shitloads of calls here.

When was the last one?

Last one was at 6:00 a.m. this morning.

Jesus.

Okay.

So that's definitely the phone he's been using to harass Abigail, clearly.

RORY: Is everything all right?

Yeah.

It's perfect, Mr. O'Hanlon.

Thanks.

Listen.

Does Dylan have a laptop?

Yeah.

We're gonna need to take that as evidence.

Okay.

What's going on?

[ Siren wailing ] WESTON: Charlie, tech team are back with the, uh, results from Dylan Kennedy's laptop and phone.

It's definitely Dylan who's been sending the abusive messages to Abigail's blog.

God, some of the stuff he wrote was vile.

He must fucking hate her.

What annoys me, though, is SOCOs still haven't found the weapon that was used to put Abigail in the hospital.

-Nothing at the house?

-At the O'Hanlon house?

Nothing.

Dylan Kennedy has used his Oyster card, all right?

He's just got off the Tube.

STEELE: Yeah.

That's him.

That's Dylan.

-Yeah.

-Probably.

Probably.

Yeah.

Just let me out here.

Dylan!

Stop!

[ Tires screeching ] [ Grunts ] Oh, Jesus.

I'm arresting you on suspicion of harassment and attempt -- Jesus!

Harassment and attempted murder.

You do not have to say anything, but it may harm your defense if you do not mention when questioned something which you later rely on in court.

Anything you do say may be given in evidence.

-It wasn't me.

-Do you -- Do you understand?!

Yeah!

It wasn't me!

Here.

Keep going.

Right.

So, Dylan, we will deal with the stalking and harassment of Abigail Lincoln.

And then we'll deal with the attempted murder.

DYLAN: I didn't do that.

That wasn't me.

-Dylan.

-That wasn't me.

I didn't do -- I-I did harass her.

I did send the texts, and I did make the calls, and I... What are you talking about?

DYLAN: I posted the stuff on her... -...on her blog.

-On her blog.

Yeah.

There's some pretty vile and malicious things, Dylan.

Do you have any idea how you made Abigail Lincoln feel?

Do you have any idea how much hell she was going through?

-Yeah, and I'm -- -Why?

-Dylan -- -Mr. O'Hanlon.

-Was I -- -Mr. O'Hanlon.

In class sometimes, she, um... she touched my arms a couple of times, and I thought that that meant -- I thought that meant that I should ask her out.

I thought that meant that she liked me.

And she... And she laughed.

She said she was a lesbian.

She laughed.

And I didn't expect her to laugh.

I...I wasn't expecting that of her.

And... And it pissed me off.

I wanted to piss her off.

Okay.

Okay.

Look.

Why don't we go through your movements this morning and, um, get a timeline?

-Why don't we start with that?

-Yeah.

I was in bed all day.

I didn't get up until noon.

It's a hell of a lie-in.

DYLAN: Yeah.

Is there anyone who can corroborate that?

Your stepfather, for example.

No.

He was at work.

How did you get the cut on your face?

It's quite nasty.

Could you just -- Could you -- Sorry.

Could you just turn your head to the right, please, so we can see that in the light?

Wow.

Was it a punch?

I was pushed against a wall.

Dylan, did you attack Abigail Lincoln this morning?

-No.

-Because if you did, Dylan, -now is the -- -He just answered the question.

Mr. O'Hanlon, I'm going to ask you to leave.

-Answer the question.

-I didn't.

I did the other stuff.

I did.

But I didn't hurt her.

I wouldn't do that.

[ Down-tempo music playing ] Have you used your toolbox today, Harry?

No.

Where is it?

It's in the art room.

Can you give me a list of what's in it?

There's a hammer, screwdriver, pliers, wrench, extra screws... -Wrench?

-...wires.

Yeah, a wrench.

There was no wrench in it when we looked in it this morning.

So you don't know where it is?

Abigail Lincoln was attacked this morning.

We know that Harry Webster was on the premises.

Do we know anything else?

Anything that happened before that?

I went through Abigail Lincoln's personal e-mail account.

She was planning to meet the college governor this morning -at some point.

-Why?

I have no idea.

I got on the college governor.

He said Abigail refused to talk about it over the phone.

She would only talk about it in person.

Speak to Abigail's partner, Liz, all right?

She might be able to enlighten us.

[ Siren wailing in distance ] How's Abigail?

It doesn't look good.

The, um, consultant came a minute ago and said that some shards of skull have compressed the brain tissue and they don't know the extent of the damage.

[ Monitors beeping, indistinct conversations ] I'm sorry to hear that.

Look, is it all right if I sit down?

-Yeah.

-Thanks.

Um, I wanted to ask you about Abigail's meeting this morning.

I understand that she had arranged to see the chairman of the college governors.

-Yeah.

-Do you know what it was about?

I do, yeah.

She was pretty stressed about it.

Basically, she found out that a member of staff was having an affair with a student.

What member of staff and which student?

I don't know.

She wouldn't tell me.

I tried.

How many members of staff are there?

About 30.

Okay.

And you couldn't get out of her who it was?

No.

I tried, but Abigail's pretty principled.

Um, thank you for that.

It's been really helpful.

[ Down-tempo music playing ] I need to talk to you about, um, Abigail's meeting that she was supposed to have this morning with the college governor.

Do you have any idea what that meeting might have been about?

I...

The college -- No.

No.

Um, I didn't -- I didn't know about that.

There's a rumor going 'round that...one of the teachers is -- is screwing one of the kids at the college.

Is that true?

My college?

No.

No, of course that's not true.

-Are you sure?

-Yes.

Yes.

Yes, I'm sure.

Rumors like this happen all the time, okay?

Most of the time, it's just... children living out their fantasies.

Nine times out of ten, it's just hearsay.

-This thing does happen.

-Of course it happens.

It just doesn't happen in my college.

So I need to just go over your alibi again.

-Okay.

Okay, okay.

Yeah.

-Where you were.

What time did you arrive at the college?

Uh, I left my house, arrived... arrived at the college just after Harry had found... ...found Abigail.

Do you have anyone that can verify that?

-Liz.

-Liz.

Liz.

I met her at the gates.

Liz.

That's Abigail's partner, isn't it?

Yes.

So Rory's alibi checks out.

He told me he was meeting Liz at the front gate to the college at 8:28.

What slightly disturbs me, though, um, is I got FIU to check Rory's bank statements to see if there was anything unusual.

Last week he paid £2,000 into Harry Webster's account.

Why would he be doing that?

Sorry this is taking so long.

It's -- It's piping hot, so be careful.

-Listen.

-Thank you.

What's the story with the two grand you paid into Harry's account?

Uh, he...was behind on his rent.

I give him an advance on his wages.

It was nothing.

I was just trying to help him out.

Okay.

Sugar?

No, no.

That's fine.

[ Door closes ] So tell me why Rory O'Hanlon put £2,000 into your bank account.

'Cause I don't think he was just making a nice gesture.

We went out for a few drinks.

He got hammered.

Told me he was having an affair with a pupil.

Rory O'Hanlon said this?

-Aye.

-Which pupil?

-Melissa.

-Melissa who?

I don't know her second name.

What does Melissa look like?

[ Exhales deeply ] Blond, 5'7" or something.

So you blackmailed Rory... -No, I didn't blackmail Rory.

-...into giving you £2,000?

I just woke up the next day, and there was two grand in my account.

He obviously realized what he'd done and wanted to give me some money so I wouldn't say anything.

You're the one shagging her.

Are you or are you not having a relationship with a student at your college?

Harry Webster told us.

You shagging a student?

Rory, yes or no.

[ Sighs ] Rory O'Hanlon, I'm arresting you for breach of position of trust.

-You do not have to say... -I'm sorry.

[ Inhales deeply ] I'm sorry.

...something you later rely on in court.

Anything you do say may be used in evidence.

Do you understand?

-You understand?

-[ Exhales deeply ] [ Voice breaking ] Yes.

[ Indistinct conversations ] So let's run through the reasons why you didn't like Abigail Lincoln.

You are a homophobe, correct?

She got you fired from your job.

She accused you of harassment.

Let's go through the reasons why Rory O'Hanlon doesn't like Abigail Lincoln.

She found out about his affair with a student.

She was gonna blow the whistle to the school governors, which would have lost him his job and ruined his career.

So we have two people for whom it would be very convenient if she disappeared and a large sum of money moving from one to the other.

Let me spell out for you what that means to me.

I think that Rory paid you to attack Abigail.

[ Chuckles ] Yeah.

That's what I think.

You're in cloud-cuckoo-land.

You've already proved yourself more than capable of extreme violence towards women.

You saying I'm a hit man now?

All of this about you getting let out of your sentence two years early because you've proven that you're no longer a danger to society -- I'm not sure if I buy it.

I don't think you have changed.

-You don't fucking know anything about me.

-You clearly haven't -- You don't know anything about me.

I think you're more than capable of doing what happened to Abigail Lincoln this morning.

You have every motive to do so, and £2,000 is a lot of money to you.

I don't care what you believe.

It's what you can prove, sweetheart.

All right?

STEELE: Was that two grand the only payment that went to Harry?

BELLAMY: I've been on to the hospital, guys.

Um...sadly, Abigail Lincoln has passed away, I'm afraid.

Massive stroke, so we are dealing with a murder inquiry.

[ Down-tempo music plays ] Okay.

Yes, Rory's alibi is watertight.

But the guy is involved in some way in Abigail's murder.

Man, I fucking know it.

Problem is the only thing we've got on Rory is breach of position of trust, all right?

-So we're gonna have to charge him and bail him.

-Fuck.

Also because Rory won't substantiate the blackmail charge, um, against Harry Webster, we've got to bail him too.

Do the paperwork.

Sorry.

WESTON: It's back to square one, essentially.

STEELE: This is fucking beyond square one, my friend.

Thank you for getting all that, Sarge.

Sign the form.

And then you're free to go.

Maybe don't go on any holidays, though, eh?

Do you know this is police harassment?

-What's police harassment?

-You wasting my time.

Me conducting an investigation is police harassment?

Yeah.

Maybe you need to conduct your investigation a bit better.

-I've got my eye on you.

-Cheerio.

Prick.

Melissa, thank you for coming in to help us with our inquiries.

What can you tell me about your relationship with Rory O'Hanlon?

How did it start?

I met him on my first day of college.

He came up to me, introduced himself.

He was...really polite... ...really kind, funny.

[ Chuckles ] He told me I was really pretty.

Did your relationship with Rory begin before you turned 18?

What does it matter?

Melissa.

Yes.

But I'm legal.

It doesn't matter.

Did anyone else know?

Rory and I had an argument.

Abigail asked me what was wrong and -- -Abigail Lincoln?

-Yeah.

Yeah.

She asked me if I was okay, and I-I told her everything.

She clearly decided that she would go and tell Rory.

He got really mad.

So mad, in fact, that he broke up with me.

That must have made you pretty angry.

I told her that in confidence.

There were -- She had no place to tell anyone about that.

It was a really bitchy thing she did to me.

She died from her injuries not long ago.

-No.

-So if it was serious before, it's critical now because it's become a murder inquiry.

Look.

Rory will be investigated for breach of trust.

Why?

He has a duty of care towards you as one of his students, -and he neglected that.

-He hasn't done anything wrong.

You were under 18 when your relationship began.

But I'm legal.

He hasn't done anything wrong.

[ Exhales deeply ] Look.

Why don't you take my card, and if you think of anything or if you need me, then call.

Oh, Charlie, how'd you go?

Uh, interesting.

I don't think Rory O'Hanlon is the only one with a good reason to want Abigail dead.

Melissa Parker is the one who told Abigail about the affair.

Abigail confronts Rory, Rory breaks it off with Melissa, and she's really not happy about it.

Look at those wounds out on the board out there.

Do you think an 18-year-old -- a small 18-year-old girl -- could inflict that much damage?

STEELE: Don't be ridiculous, Jack.

When I was 18, just as well as I could now, I could have battered the shit out of someone with a wrench.

Look, I had to tell her, 'cause she didn't know that Abigail had died, and it gave her a second of pause, maybe, before it was back to, "What's gonna happen to Rory?

Rory's so lovely.

I love him."

All of this nonsense.

It was just -- She was weird and cold and shifty, and there's just something not right about her.

BELLAMY: Are you saying Melissa could feasibly have killed Abigail Lincoln?

Yeah.

This little gem turned up on Orden Street camera 8.

That's a person of interest, isn't it?

Melissa Parker?

STEELE: Yes, it is.

When she went down, she was taking off her bag, wasn't she?

STEELE: Huh.

What's she doing?

Melissa comes down this street, and the car was here.

So it's this one.

I'm not sticking my hands down there.

[ Cellphone buzzes ] Hello?

Who's that?

Uh, I don't know.

Unknown number.

Called and then hung up.

Hold on a sec.

-Hi.

This is Melissa's phone.

-Jack?

Sorry I can't take your call, but if you leave a message...

It's Melissa Parker.

-Thanks.

-[ Beep ] Why would she call me and then just hang up?

-Guys.

-Oh, hello.

Monkey wrench.

Okay.

That's good.

Search team found it in the drain at Orden Street, which is where Melissa disposed of it.

-STEELE: Result.

-Yeah.

I haven't forensicated for DNA, fingerprints yet, but it looks like you were right about Melissa.

What's niggling me, though, is this silent phone call.

Nothing, nothing on the phone, then she hangs up.

I just...

I rang her parents.

They've not seen her all day.

The phone's going straight through to voicemail.

I gave her my card when I saw her earlier and said, "If you need anything, if you want to tell me anything, then call me."

I don't know.

Maybe she's calling to confess.

Maybe she's on the run.

Whatever she's doing, we need to find her, okay, Charlie?

So let's put a live cell site on Melissa's phone, okay?

Let's try and catch up with her.

-Yeah.

-Yeah.

Okay.

Charlie, your boyfriend's downstairs.

I have one of those now?

Harry Webster.

Just can't keep you away, Mr. Webster, can we?

-Have you guys seen this?

-What is this?

It's a printout from the school message board.

That's Melissa saying she was the one who attacked Abigail.

So it wasn't me, like I've been saying.

Why were you on the school message board?

I was looking to see if anybody had put any information up.

WESTON: That confession Harry brought in -- Melissa's confession to the online forum.

Uh, I traced that back to Melissa's phone.

The live cell site led SOCOs to the river.

STEELE: Actually, I'm certain that that scrap of material caught in the railings matches the dress that Melissa was wearing.

That, uh, light-colored dress with the stars on it.

[ Telephone ringing ] Everything looks like suicide, but... A shame.

Yes?

A body matching Melissa's description has washed up at Limehouse Reach.

There you go.

WESTON: Mr. O'Hanlon, thanks very much for coming back in.

Uh, sit down, please.

RORY: I'm okay.

I'd like you to sit down.

Thank you.

[ Paper rustling ] Listen.

I'm sorry to be the one to have to tell you this.

I really am.

But Melissa Parker's dead.

Yeah.

I'm sorry.

She's dead.

But she confessed to Abigail Lincoln's murder.

-Jesus.

-Mm.

So she committed suicide... -Why?

-...apparently.

Has she ever expressed to you in the past, um, any sort of suicidal tendencies?

Yeah.

-Was that a "yes"?

-Yes.

Yes.

Uh, one of the main reasons why I was afraid to break up with her...

There is an officer you can talk to if you're feeling emotional.

No.

-I am s-sorry.

-Yeah.

You're free to go, Mr. O'Hanlon.

Thanks.

Thank you very much.

[ Telephone ringing ] Melissa's confession is still bugging me.

-Postmortem is in.

-Yeah.

Melissa Parker's injuries are not consistent with a body hitting the water.

These are defensive wounds -- fingernails broken, bruising to the temples -- so Melissa Parker did not commit suicide.

She was murdered.

WESTON: Do you want to take this one?

STEELE: Yeah.

-Harry.

-What is it now?

WESTON: How's it going?

We've got to have a quick chat down at the station.

-Huh?

-What about?

Best to talk about that down at the station.

-I've answered your questions.

-We'll do it at the station.

-Get in the car.

-Let go of your bag, please.

Harry Webster, I'm arresting you on suspicion of murder.

You do not have to say anything, though it may harm your defense if you do not mention when questioned something which you later rely on in court.

Anything you do say may be given in evidence.

-Do you understand?

-This is bollocks.

Do you understand?

-Yes.

-Thank you.

You've fucking made a mistake again.

You've made a mistake again.

-In the car.

-Keep talking, Harry.

You have killed in anger before.

So in my mind, it's not a massive leap to think that you killed Abigail, because there are a number of reasons that you despised her.

I've told you already I didn't kill Abigail!

And I didn't kill Melissa.

You're just putting things together and trying to piece this to make it fit onto me, and it doesn't fit!

It doesn't fit!

You're a violent man, Harry Webster.

Let's not forget that you killed your wife.

Yes, I killed my wife!

And I haven't been able to forget about it for eight years.

Every day I have to live with that, all right?

Every day.

And I am fucking sorry that it happened, and it's the biggest mistake of my life.

But I did not kill Abigail, and I did not kill Melissa.

STEELE: Forensics on the wrench are back in.

So it's definitely our murder weapon.

The blood and the skin fragments, et cetera, on the business end belong to Abigail Lincoln.

On the handle, we have Melissa Parker's DNA.

It's no great surprise.

We've got Harry Webster's DNA -- also no great surprise.

But we have Rory O'Hanlon's DNA as well.

What if Melissa's confession is bullshit?

Maybe Melissa is just weapon disposal.

She'd do fucking anything for him.

BELLAMY: So with the silent call, what is that now -- a distress call, do we think?

Can we find out exactly where Melissa Parker was when she made that call to you, Charlie?

[ Down-tempo music playing ] CCTV footage is in from Cravenhill Street.

That's where Melissa made the silent phone calls to you.

-But guess who's there with her?

-[ Computer beeps ] -This is the money shot.

-Ah.

Here she is, right?

Making the phone call to you.

Rory, pissed off, rounds the car, shoves her in.

I reckon he drives off, murders her, dumps her in the river.

Then he takes her phone, writes that little confession, posts it on the online forum to make it look like a suicide, and then he's off scot-free.

I've spoken to the Gardaí.

Rory O'Hanlon has no criminal record in Ireland, but they did have some juicy nuggets for us.

This is a picture of Rory's wife, now deceased -- Louise O'Hanlon.

How'd she die, Jack?

WESTON: Unexplained death.

Domestic drowning, which has all sorts of alarm bells ringing.

There are four open cases in the Republic that I know of -- all unexplained deaths, all domestic drownings, and -- and, terrifyingly, Rory O'Hanlon was living in the vicinity of all of these women at the time of their death.

Jesus Christ.

He's a serial killer.

[ Up-tempo music plays ] MAN ON RADIO: Control to all units.

Suspect Rory O'Hanlon sighted at Pencross College.

Okay.

We're on our way.

There's been a sighting of Rory at the college.

Vince, with me.

Charlie, we'll take the first floor.

Fine.

I'll take low hall and stairs.

Philip, if you come with me.

This is huge.

Wait there.

STEELE: Rory?

Rory, t-- Rory!

Jack?

Jack, something sighted.

He's on foot.

We're in pursuit!

All received.

We're on the second floor.

Heading to you now.

Down.

He's downstairs.

Jack, he's heading to the basement.

Charlie, hold position.

Coming to you now.

Jesus.

[ Sighs ] Control from D.C. Steele.

MAN: Control.

Go ahead.

We've lost sight of the subject in the basement.

We'll continue to search.

Fuck, man.

This place is a fucking maze.

Phil, cover off that route.

Keep on channel 12.

[ Grunts ] Phil?

Are you okay?

Um, control from D.C. Steele.

Urgent assistance.

Officer down.

Ambulance required.

We're continuing the search.

MAN: Control.

Received.

Charlie, clarify position.

Charlie, clarify position.

Charlie -- [ Static ] Fuck.

She's gone to clicks.

Closest subject unable to talk.

On the way.

All units, radio silence.

-Charlie?

-[ Exhales deeply ] I swept down here.

There are multiple entrances and exits.

He could be fucking anywhere.

I've heard him.

But it's like a fucking rabbit warren here.

-Rory!

-Rory!

WESTON: Rory!

Stop!

Subject sighted.

He's on foot, trying to get away.

Rory, stop!

Stop, Rory.

Stop.

Rory, stop.

Stop.

Stop.

Drop the bag.

Drop the bag.

Drop the bag.

Drop the fucking bag.

Drop the fucking bag!

Rory, I'm arresting you on suspicion of murder.

You don't have to say anything, though it may harm your defense if you do not mention when questioned something that you later rely on in court.

Anything you do say may be given in evidence.

-Do you understand?

-You understand?

Do you understand?!

Yes.

For fuck's sake.

We got him.

[ Sighs ] [ Siren wailing in distance ] The bag we took off Rory when we arrested him had a shirt in it that was covered in blood.

I sent it down to forensics, but I'm willing to bet a lot of money that the blood belongs to Abigail Lincoln.

Of course, you see here on the CCTV Rory apparently arriving at the college at 8:28.

He's wearing a brown checked shirt, so he's obviously attacked Abigail and changed his shirt.

My God.

That's two women in 24 hours.

WESTON: Yeah.

[ Down-tempo music playing ] [ Door opens ] In the bag that you were desperately clutching when we arrested you was a shirt covered in blood.

And the blood belongs to Abigail Lincoln.

Abigail wasn't planned.

I tried to persuade her not to tell about myself and Melissa's relationship.

She was quite stubborn about it.

I saw red, picked up the nearest thing to me, which was a wrench... and crushed her skull in.

How did Melissa end up with the wrench?

Melissa was waiting for me down in the basement.

She wanted to see if I'd persuaded Abi not to say anything.

Well, I guess in my own way I had.

And I told her to get rid of the wrench.

This is you with Melissa... ...sort of manhandling her into the car.

Not long after that, she died.

She's a good girl.

BELLAMY: She was a good girl.

RORY: She was a good girl.

I'll miss her.

You groomed her, didn't you?

You picked her out the minute she set foot in that college.

Someone who could just do your bidding, who you saw as weak and naive.

She was absolutely besotted with you, and you abused that.

[ Laughs ] Defense wounds.

Look at these pictures.

Look at them.

Look at her fingers.

Look at her neck.

Before you shoved her into that car and drove her to that river, she made a silent call to me, which was a cry for help, I understood, but not in the way that I thought it was.

She wasn't trying to confess to something that she felt so guilty for.

She was terrified of you because you were about to kill her.

Look at her hands.

Look at her hands.

Look at the pictures, Rory.

She was 18.

18.

Do you have anything to say for yourself?

[ Mid-tempo music plays ] [ Paper rustling ] Who's that?

RORY: Oh.

[ Exhales sharply ] WESTON: That's Louise.

Your wife, now deceased.

[ Paper rustling ] Melissa Parker, your lover, now deceased.

They look pretty similar, don't they?

Any other similarities about them you want to tell me about?

No?

Melissa Parker...was rushed.

Not as rushed as Abigail, of course.

Louise.

Mm.

Louise was meticulous in its planning.

It took me months.

So I was never suspected for it.

It really was quite beautiful.

Are you getting sloppy now?

Is that it?

Don't judge me on those two, Jack.

Okay, Rory.

Who are these four women?

Oh.

[ Paper rustling ] Oh.

[ Laughing ] Oh.

Wow.

This...

I don't know who that is.

She must have killed herself for real.

You're still missing one, though.

She's my favorite.

Mm.

You say we're still missing one?

So beautiful.

[ Inhales deeply ] I'll show you another beautiful lady.

-RORY: [ Chuckles ] -BELLAMY: Yeah.

RORY: Oh.

BELLAMY: It's Mummy, isn't it?

WESTON: She topped herself.

How old were you?

8.

So ultimately, she abandoned you, didn't she?

WESTON: What would she think now... of you?

She'd be pretty disappointed.

Why do we feel that we need to compartmentalize everything?

Why do we feel that we need to define what man does?

What if there is no reason?

Is that so frightening?

What if the man just wants to kill the fucking bitch 'cause the fucking bitch was acting like a fucking bitch?

Why does it always have to come back to the mother?

What did she do that was so wrong?

I'd press that panic button now if I were you.

Bitch!

Fucking bitch!

-You fucking bitch!

-[ Alarm blaring ] -That's it.

That -- -You bitch!

WESTON: Sit down.

Sit down.

Sit down, mate.

[ Alarm continues ] I don't know.

We don't often get happily ever after, do we, Charlie?

But this one?

My God.

Just made my blood curdle.

I think today was a new low for me, to be frank.

I've never seen anything quite like it.

How's he been today?

STEELE: Best behavior for once.

Pains me to say I'm actually quite pleased to have him back.

I think you did a fantastic job today.

Thank you.

I actually got you a present as well.

Huh?

That's the paperwork.

-See you later.

-Ah.

You're such a cock!

I can do this tomorrow, right?
