Silent Witness

You've found a body. Lorna.

You've got no alibi but you've got a motive.

I wouldn't hurt her, OK? I never touched her!

Ali, you should see this.

We've had a walk-in, a couple. Their daughter went missing. Ruth Tresize.

She was friends with Lorna Katz. They were at school together.

My husband was physically abusing our daughter.

I slapped her. Once.

So you said.

It's Kieran Vale again for DI Ashton.

I'm at a place where Lorna and Ruth and I used to hang out.

How did you find out where I live?

I followed you from your office.

I didn't protect my daughter as I should.

Not even from my husband.

Aaron Logan's got an alibi for Ruth and Lorna.

Kieran Vale has, an' all.

Look, we're going to make this right, like we did before. Come on.

And we're going to sort it now.

I need you to do something for me, yeah?

Aaron Logan.

Is that who they're after?

You didn't tell her, did you?

No, but I didn't say that it wasn't him, either,

so I'm worried that it's kind of like I've confirmed it, isn't it?

We're going to need everything, I'm afraid.

She's not well enough to be interviewed.

Well, she's been seen by the psychs and they've OK'd it.

Well, that's absurd.

Is that a qualified opinion?

After what's just happened?

Well, someone told her that Aaron Logan was a suspect.

She'll have known that anyway, won't she? She's always known it.

What, for Lorna Katz and Kieran Vale? No.

There's no leak here, not with my team, so it has to be with yours.

He's a lucky boy.

Another inch and she'd have punctured his lung.

Something that doesn't make sense to me,

for an innocent man,

how come he was running?

He wasn't running.

He had his passport with him!

I'll tell you what's happened here.

You couldn't pin anything on him, so you tell a lot of shit to some

- psycho bitch hoping that she'll take care of things! - Stop it, Ben!

Innocent people don't run, Ben.

- What kind of world do you live in? - Ben...

No, he was being targeted again.

You people have never let him alone!

You did this!

Look at him! Go on, look at him!

'I don't want to fight this.

'You want to talk this through with me before you go on?

'No.

'I know what I did. I was of sound mind when I did it,

'and I'd do it again.

'Did you know Aaron Logan was a suspect

'for Lorna and Kieran's deaths?

'Ali?'

How did you know where he'd be?

I knew where he worked.

He got a job there when he left school.

What, so you've stayed in touch, have you, over the years?

Not since Ruth, no.

So, you went to the restaurant, what, more in hope than expectation?

'And he wasn't there.

'No, but his brother was.

'Someone told you Aaron was a suspect, didn't they?

'The pathologist.

'Dr Alexander?

'I called at her house and I asked her to confirm it

'and she met me a few days later and I asked her again.

'And did she?

'Did she confirm it?

'Not in words, no, but she told me in other ways.

- 'What do you mean? - Her reaction.

'I don't understand.

'I read her face.'

She didn't need to actually say anything.

And I read Aaron Logan, too, didn't I?

Eventually.

Can I just check, you're not actually next of kin any more,

are you, Mr Tresize?

We're still married, legally.

Look, what she did is so out of character...

Well, there have been mental health issues in the past, I believe?

Relatively minor issues, yes.

Depression, understandably.

What's going to happen to her? Will she be charged?

Yeah.

And her state of mind, will that be taken into account?

Well, that's for the courts and the DPP to decide.

Why don't you go home?

I'm OK.

You, you shouldn't have to deal with all this stress.

I'm fine.

Hey, come on.

We let him down.

I don't mean now.

I mean, after your mum died.

He was just a kid.

There was never anybody more loyal than you.

Yeah, to you.

He should've come to live with us after he left the care home.

I was so stupid.

I wanted you without any baggage.

Don't do this.

Do you know what's worse?

The more they went after him,

the more I thought maybe he had done all this.

Loner, can't hold on to a woman or find anything in his life.

Well, it fits, doesn't it?

Except... except it doesn't.

Hey, hey. Come on.

Sh, sh.

Allowing a victim's mother access into your home. Was that ethical?

I didn't let her in.

But you talked to her.

Look, she turned up on my doorstep, OK? We talked.

She was struggling. All I did was empathise.

No, what you did was overstep your role.

Do you have any idea how it must feel to lose a child

and have no closure?

Do you?

- No wonder the woman's falling apart. - Nikki, leave it...

OK, yes, she put me on the spot, but she pretty much knew

everything already -- or suspected it.

How?

How should I know?

No-one ever told her that Aaron Logan was a suspect,

not now, not even...

Not even when Ruth disappeared. So, how?

It's a community. The people know one another.

The kids went to the same school.

I mean, you honestly think that things stay secret?

And you... you mention ethics, you know.

What's unethical about trying to help someone with their loss?

Yes, showing them their loved ones in the chapel of rest,

THAT is what you're supposed to do -- not invite them into your

home and let them cry into your gin.

I've told you, I didn't let her in!

Look, mistakes may have been made on both sides here.

Oh, ever the diplomat, Thomas.

Kieran Vale's calls went unanswered, your officers didn't even

notice Ben Logan leaving the restaurant.

Because they were looking for Aaron, not Ben.

Nonetheless, I suggest if we want to take out our frustrations on

something, then let's take them out on finding the killer.

Hey... hey!

The police are watching me.

No, they're not, man. They've got nothing on you.

You're the victim in all this.

Whatever, I'm out of here.

Hey, Aaron...

Can we rerun the fish debris? Only, this time, focus on

Chris Tresize rather than Aaron Logan?

Just because the debris doesn't match Logan's clothing

doesn't make him innocent.

It simply means THAT evidence doesn't incriminate him.

I'm aware of that.

Erm, it'd be worth checking out Ben Logan, too, Aaron's brother.

He would've known the Tresizes a little.

They were living together, were they, the brothers?

- No, Ben was living with Sarah, but... - So there's no evidence against him?

No, but belt and braces.

What else have we got?

Anyway, this, er, this potential witness.

Have we managed to trace the call?

Pre-pay mobile.

Shit. It has to be her.

OK, so where's the camera?

There.

Uh-huh.

OK...

.. she was standing somewhere around here.

This is the only place she could see the assault from.

OK.

Jack...

.. I just have to say that

Nikki Alexander's really dropped me and my team in it.

No, I know you don't like me saying that.

I don't think it's Nikki that your bosses are going

to be interested in.

Your boys staking out that restaurant were napping on the job.

Put me in my place.

She was eating something, wasn't she?

Yeah.

Why don't you go get your head down for a bit?

I've gotta go.

Where?

Aaron?

Aaron!

'A few moments after she left,

'I went out to look for her,

'but I didn't see which way she went.'

'Chris went after her,

'but he couldn't find her...

'.. and he came back about half an hour later,

'soaking wet.

'It had started raining.
