Sorry.
You lied to us.
About Carol Fincher.
You arranged a meeting via a dating website.
I did.
I lied.
And when I realized she was an ex-employee, I backed off.
Nothing happened.
But you deleted the account after talking to us.
Why?
I have affairs.
A couple of years ago, for financial reasons,
I signed over half the company to my wife,
and, as you know, there is nothing more greedy...
than a deceived woman.
Just when I thought I couldn't like you less.
What were you doing on Wednesday night?
This Wednesday?
Between midnight and 8:00 a.m.?
I was at home with my wife.
You were seen leaving a black Fiesta on Hampstead Heath.
You're lying.
And I'm sick of being lied to.
One hundred percent. It's him.
Rav?
- It's him. - Is he cooperating?
It looks like it. He's offered us access
to his e-mail, bank details, travel itineraries.
- What was he doing on the Heath? - What he's always doing,
being a cheating dickhead. This time with a Cassia Beckworth.
Good. Well, hold him, keep me in the loop, dig into his alibi.
I'll get Forensics to look at Cassia Beckworth's Fiesta.
Later. Come with me.
Both of you.
Can you shut the door?
You said you didn't know.
About Grace Gibson and your husband.
I didn't. Not until Tim told me.
So, why did you access CCTV outside her house?
- I was asked. - No.
Not when we were 72 hours before anyone knew she was dead.
I was helping DI Williamson.
I knew that she was listed as missing.
- Did he ask you to help him? - No.
I was learning about the system.
I thought I might as well do something useful.
So, you knew nothing about Jason and Grace Gibson?
Before she was killed?
- Not at the time. No. - Did it lead anywhere?
- Sorry, what is this? - No minicab or delivery van?
- Like the other crime scenes? - I wasn't looking then.
Look for them now.
Check the CCTV footage the night of Grace's murder again.
Immediately.
Hey!
Hiya.
What a surprise.
Do you live here?
What are you doing here?
I've just been seeing a friend up the road.
So, where you off to?
Do you fancy grabbing a coffee?
I'd love to, but I'm already running late.
Do you know, I could think that you're trying to avoid me.
No. Don't think that.
I-- I've just got this lecture and I can't miss it.
- You can walk with me, though. - Great.
So, is everyone nice to you here?
At uni?
Everyone treat you all right?
Yeah, they do.
- Why? - Why?
I don't know.
I really care about you.
Anyway, Peter, thanks for keeping me company.
My pleasure.
Oh, hang on. Heh.
I almost forgot.
Hope you like it.
Oh.
Thank you.
What would you say to having dinner together?
Yeah. Yeah, we should fix something up.
Yeah?
Definitely.
Good.
I'll see you, Peter.
See you.
Don't.
- Does this look overdressed? - For what?
I'm meeting Andrew Barnes about Lambeth today.
Can't you postpone that?
So we could go somewhere, you and I?
Take care of each other. Have a few days off?
I don't take days off.
Is Henry gonna be there?
No. Why?
Well, he is familiar with the project.
Knows what Barnes wants to hear.
It's not his fault we're in the position we're in.
He warned you about Lambeth.
So did Grace.
You let your personal feelings about Henry get in the way.
He irritates me. Always has.
Maybe you should change.
That doesn't do you any favors.
I inspected the Lambeth site earlier.
I have no choice than to issue you
with a fail notice, Mrs. Gibson.
On what grounds?
Green space, accessibility, sustainability.
You're breaking our planning agreements at almost every point.
Well, in our view these changes were made well within its parameters.
You've got until Monday to submit a proposal
detailing measures you'll be taking
or else we'll shut it down.
And you risk being blacklisted from any further contracts on public land.
Surely there must be another way we can solve this
that benefits both of us.
I'm not sure I follow you, Mrs. Gibson.
I think you do.
I hope I don't.
Um, we've been going through a very difficult time recently.
I'm sure you've heard about my sister?
I'm really sorry for your loss,
but you can't ask me to ignore our planning regulations.
No, of course not,
but given everything that's happened with Grace and how it's affecting us,
I think we would definitely benefit from more time.
Your personal situation is why you're getting till Monday.
I'm sorry.
An awful little man.
I'll bring someone in to come and have a look at this.
Why don't you do it?
Me?
Yes, you.
Sure. Yeah. Absolutely.
I, um...
Yeah, I'd love to. Thank you.
I, um...
Just checking up on the place.
Sylvie wants it on the market as soon as possible.
I'm just collecting some of Grace's things.
I miss her, too, you know?
In we go.
Sit, sit, sit.
Sit. What's the matter with you?
What's the matter with you?
Should be here any minute.
Hassan El-Sayed?
DS Marcella Backland.
Can I have a word?
Your vehicle was parked at the junction of Hallum Street and Ferndell Road
last Wednesday between 22:50 and 23:25.
So?
So, a murder was carried out around that time.
Murder?
Did you see anything?
Last Wednesday?
No, sorry.
Your car was parked for 35 minutes.
You didn't see anything, no man or woman leaving the house?
Thirty-five minutes?
- Did I pick up or leave a ride? - No.
No. Oh, I was on my break then.
Probably trying to sleep. Sorry.
- I wish I could be more help. - Thanks.
That's very helpful. Thanks.
The taxi arrives outside Grace's house at 22:51
and he stays there for the next 37 minutes until 23:28.
It's all logged.
Here.
- So, the driver might have seen something? - No, I spoke to him.
His name's Hassan El-Sayed.
He was on a break, taking a nap.
Nothing suspicious.
There's been an attack. Looks like our killer.
Need you all down there now. Now.
Can you give us a description?
He was all in black.
It was over in seconds.
And then I found these.
What did he want?
Can you tell me about your movements today?
Yes. I went down to the swimming pool for my senior swimming session
and then I stopped off at Dewson's to pick up the dog.
Who's Dewson? Is that the dog sitter?
No. I'm his.
Sorry, Mr. Davies. There's usually no dog in the house?
No.
What do you think he was up to?
- Found this. - What's that?
I don't know. It's unmarked.
- Just by the wall where he jumped. - That's all?
No. Got a footprint. Size nine. Should have the make and brand in an hour.
That's Cullen.
Cullen's a size 9.
- Oh, God. So are 10 million others. - He's out now.
We don't know the last time Guy Roberts left him unattended.
Clive Bonn's at the station. We haven't got anything else.
- It's not enough to bring him in. - Rav, please.
What about an invitation?
Off the record. Give me one last chance with Cullen.
All right, fine.
If you can get him to talk, you bring him in.
- All right? - Thanks.
Hi.
How was running?
Yeah.
Yeah, it was great. It was good.
Um...
I've been thinking...
about Bendek.
I'm not really happy having him here.
Why not?
Something happened?
Oh, no, no, no. I just, um...
I don't know, I just don't feel comfortable
with someone being in the house.
Well, he's all right.
We need the money.
The thing is we don't.
Not really.
Yeah, well, like I said, you know, it's good to save a little bit.
You know, for the future. I mean, anything can happen.
Like what?
Like anything.
I don't want you to worry.
This is Ade. You know what to do.
Hey, Adrian, it's me.
Where the hell are you?
Call me.
Where were you between 11 and 1 today?
Well, that's it?
Straight to the point.
You're not gonna offer me anything to drink?
- Would you like a drink, Peter? - Tea, please.
With milk.
Why did you do it?
Why did I do what?
Come here voluntarily?
I'm out of prison.
I've paid my debt to society and I'm trying to start anew.
The sooner you realize that you're wrong,
the better for me and the other people around me.
With Maddy Stevenson?
You're ruining my chances of a normal life.
Where were you between 11 and 1 today?
Out walking.
Enjoying my freedom.
You're gonna have to do better than that.
Can I have your shoe?
Your shoe. I need to photograph it.
The sole.
If you're gonna keep them, I need some new ones to go home with.
Sorry to hear about the dog.
You can put your shoe back on.
I'm guessing this has to do with whatever happened
between 11 and 1 today.
We're gonna need to get into yours.
I need your keys. Or is it a key card?
This is the last time I'm helping you, Marcella.
You stay away from me.
Or what, Peter?
Grace!
So, how is everything going?
I'm good.
Better.
And Jason?
Fired.
- What? - Yep.
Yeah, it's a real-- It's a real pity.
Um...
Have I missed my moment?
There was a moment, was there?
I wasn't really in a good place.
I know.
And that's why I didn't act on it.
Is that why you've come?
I'm here because I still care about you.
Thanks.
I'll see you tomorrow.
What was he doing here?
What happened?
Jason, what happened?
I haven't felt anything since the morgue.
I needed to feel something.
So, I paid someone to hit me.
It worked.
Are you fucking kidding me right now?
I never meant to hurt you.
What do you think getting a new girlfriend knocked up
would do to me?
You take those.
Wait till they kick in.
And I'll drive you back to Greg's.
Hi. Hi.
- How are you? - Good.
- What are you doing here?
- Are you looking for Matthew? - No.
What do you think of me?
I like you. You're...
You're good for Matthew. You're...
Why?
It's just that we both care about him
and I just thought it would be good if we were friends.
Oh, God, I thought we were.
Yeah, better friends.
Sure. Yeah.
- Yeah. I'm sure we can work on that. - Good. Good.
You got a moment right now?
- Yeah. Sure. - Excellent.
Right, good.
Are you serious?
Yeah.
Matthew said that you weren't allowed to see her at the morgue.
You need closure.
- Believe me. - What the hell do you know about it?
You okay?
Yeah.
Better than I expected.
Thanks.
Sylvie showed some confidence in me yesterday.
That's good.
Yeah, it's good.
I want my job back.
You should have thought of that before--
Before I started a relationship with Grace. Yeah, I know.
But that's not what we did.
We loved each other.
She's dead.
Now I have nothing.
So, I really need this job.
"Before you started lying to me" was what I was about to say.
We didn't lie, Sylvie.
We just didn't tell the truth.
Oh, quit the lawyer bullshit.
Sylvie.
This wasn't work.
We didn't want you to know.
I want my job back.
No. You don't get things in life, Jason. You earn them.
Listen, Jason, it must have seemed a bit odd-- Ow!
That hurts.
Shut it.
- I'm allowed to grieve. - Yeah.
Yeah, you are.
But I wonder what Sylvie would say about the way you do it.
Now, tell me about the company.
Where are we with Clive Bonn?
Cassia Beckworth's confirmed she did pick him up at the Heath
and they had sex.
We've had a preliminary report on Miss Beckworth's Fiesta from Forensics.
A 1.6 L Ti-VCT Duratec I4 engine.
Black, as we know. Mileage was just under 3000
- which is quite low. - Jesus, Mark.
- Is there anything of interest in there? - Yeah.
There's no signs of damage to the glass or metalwork.
No signs of repairs and no traces of blood.
Marcella, are you with us?
Well, we know it wasn't the car that hit Cara
and Bonn was here during the attempted attack on Walter Davies.
Has anyone got anything on the white plastic card
that was found in Davies's garden?
Short version.
It's incredibly hard to retrieve information from them,
so I've asked a hacker friend to help.
And there was nothing on the minicab?
We got DNA results from the Gibson house.
- Blood type O. - Cullen was O.
He's also a man.
The blood's from a woman.
There's no match in the DNA database.
Get DNA samples from every woman
that might have been in Grace Gibson's house.
Surely you've done yours by now.
- I never went to that house. - It doesn't matter.
Nurse's office, second floor.
Marcella.
Okay, wait for me here. I'll take this car back for you.
Thanks, brother.
The driver is called Sergei and he'll text you when he's outside.
- Thank you. - No worries.
So, let me confirm the address with you.
- Okay, come on. - All good?
- Let's go take this one back. - Okay.
You good?
Thanks, brother.
The police visited me yesterday.
It wasn't about your visa.
You were parked at the junction of Hallum Street and Ferndell Road
- for 35 minutes yesterday. - What?
Someone was murdered in a house you could have seen from your taxi.
They thought it was me in the car.
- Seriously? That's what it was? - What did you see?
- What's wrong, my friend? - You saw something?
A woman came out, dragged something heavy over to her car
and drove off.
- A woman? - Yes! I saw her. What's wrong with you?
Go home and hide.
What do they want with us?
This is for my dog, you bastard!
- Hey. - Hey.
Thanks.
What's Vannux?
It's an antidepressant.
Why are you looking at that?
It's just research for the client.
So...
It has nothing to do with what you said before?
You-- You're okay? I mean, we're okay?
Yeah.
Okay.
Oh. Bendek?
Is that you?
Can't even be bothered to say hello.
Well, if you've gotta go, you've gotta go.
Sorry.
Oh, I'm so sorry.
It's all right. Are you okay?
Yeah. I'm so sorry.
Excuse me for a second.
Maddy, are you all right?
Sorry to bother you. I'm just--
I'm getting a bit freaked out.
About what?
I haven't heard from my boyfriend in days.
Right. Does Peter know about him?
No, I don't think so.
- Does he know where you live? - Yeah.
He gave me this perfume. It's my favorite.
Adrian normally buys it for me.
Where are you right now?
Hang on a minute, the lights are on.
- It must be Adrian. I'll call you back. - You can call me anytime,
but, Maddy, you've got to listen to me. The--
Oh, fuck.
Can you get eyes on Peter Cullen for me now?
Adrian?
You could have called, you know?
I thought we were getting on so well together.
Peter, I can explain.
"The subject is looking for constant confirmation
and is therefore easy to befriend and get close to."
So, what do you wanna know?
What is so important that it's worth deceiving and betraying me for?
Peter, please.
Do you wanna know if I killed them?
Do you wanna know if I'm the Grove Park Killer?
Where's my backup?
It's all right.
Get off! Just stay away from me.
Maddy. Can we get the medics in?
Slow it down, Maddy.
Breathe.
You're okay.
Okay, you're okay. You're okay.
Breathe.
It's all right. It's okay. You're safe. You're okay.
Get him out of here.
Can we get the medics?
We caught him.
It was Cullen.
Rav.
Cullen used to sit and watch them die.
It's what he did to his victims in 2005.
It was what he was gonna do to Maddy.
He'd move a chair closer so he could get a better look.
I haven't checked the crime scenes,
but whoever killed Liz Harper, Carol Fincher, Benjamin Williams,
they didn't move anything.
They couldn't have been sitting over them, like Cullen did in 2005.
These latest victims,
Cullen didn't kill them.
