♪ One morning in the month of june

♪ Down by a rolling river

♪ A lonely traveller chanced to stray

♪ And he beheld his lover

♪ Her cheeks were red, her eyes were brown

♪ Her hair in ringlets hanging down

♪ She'd a lovely face without a frown

♪ just as the tide was flowing! ♪

Don't dilly-dally, darling.

There's not much point in paying for sunrise yoga

if the sun's already risen.

Inhaling. All the way up.

And exhale.

Hands right down by your sides.

Just keep moving with your breath.

Well? Well, what?

It's just the last time you did a yoga class,

you were feeling guilty about having cheated on your theory test.

I'm not feeling guilty.

Oh, for goodness' sake.

I saw you and Archie together the other night, kissing.

That's not what...

It isn't what you think.

Archie tried to kiss me, but I slapped him

before he got the chance.

You slapped him? Yes.

Quite hard as well. How very Dynasty of you.

I'm dreading seeing him again, to be honest.

And there I was believing there was nothing going on between you.

There is nothing going on.

Clearly. There is nothing going on.

So you've told Humphrey all about it, then?

No.

But l just don't want him to worry,

or to hate Archie, or do anything stupid.

Secrets have a funny way of coming back

and biting you in the behind, you know.

This isn't a secret.

I just feel like l've given Humphrey enough to digest recently,

telling him that l'm in business with my ex-fiance,

that l don't want a baby.

How's Humphrey been about the baby thing?

Perfect.

Wonderful.

Saying all the right things.

That's the problem.

I'm just not sure he's being completely honest.

Morning. Morning, Esther.

How's it going? It's almost done.

Just overhauling now.

Making sure there's no risk of rekindle.

You suspect arson?

Well, there's definitely a smell of petrol.

And the graffiti strongly suggests that might be the case.

Oh.

I'm guessing this isn't a pig farm.

Arable and sheep, I think.

Right. l'd better talk to the owner.

Ah! That'll be Lucas Fairly, the farmer.

He called it in.

OK. Cheers.

Thank you.

Lucas Fairly?

Not enough that they burned down my barn,

they have to ruin my bloody tractor as well.

Any reason someone might want

to set fire to your barn and write "pig"?

Not that I can think of. That's a nasty-looking scratch.

Oh, yeah.

Wrestling with a fence post.

You called in the fire, is that correct?

Yeah. I woke up about 3:30, I think,

saw the fire from the window, called 999.

Did you see anyone or anything else unusual?

No. No-one.

Are you married? Partner? Anyone else living here?

Who's asking?

No.

Does anyone else work here?

No, it's just me.

I have seasonal workers that come in during the busy periods

for the harvest and the like, but no-one at present.

Right. Well, l'll have a look around.

If you think of anything that could be relevant,

give us a call. Should I take your number?

Just in case.

Station number is online.

Well, l think I know who the pig is.

Is it all right if l have a look? Yeah.

I'll just follow you in.

Blimey. Big. Mm.

Huh.

What have you got?

Dunno.

Button, by the looks of it.

Ah! Oh.

Oh, "Duck," yes. Oh, yeah, I got it.

A bit earlier with the warning next time, Selwyn.

Apology accepted.

Oh, hello. Nice overalls!

Well, all the gear and no idea is my new mantra.

What's this in aid of?

Can I not treat my beautiful and perfect fiancee

to a healthy and balanced breakfast?

Well, when you put it like that...

Humph... How was yoga?

Yes. Good.

Well, apart from the fact that everyone was twice my age

and three times as flexible. Oh, yes.

Well, now we're no longer going to be drowning in nappies

and carrot puree...

...perhaps we can spend more time on our hobbies.

You could...you could go to yoga more than once a decade,

and I could finally take up, er...

Squash? Crochet?

Yes.

Good idea.

I could crochet you a nest, perhaps, Selwyn.

It's just a thought.

What?

You just put the whole thing in a jar?

Mm-hm. Then you give it a shake,

and then all the skin comes off.

Well, I never.

You two aren't discussing horror films again, are you?

Garlic, sir. Right.

Just when you think you've got life sussed.

Morning, sir.

What have you got?

Suspected arson at Vicarage Farm, the hay barn.

Petrol, the likely accelerant. Graffiti found nearby.

Possible message. "Pig."

The farmer, Lucas Fairly, called it in around 3:30am.

Silver button found at the scene could be related.

Well, graffiti suggests it's personal, not random.

Did Lucas Fairly have any idea who it might be?

He says not. But?

I don't know.

There was something a bit...off about him.

We're just doing background checks on him now.

Excellent.

Anyone fancy a cuppa?

Oh, yes, please.

No luck?

I was hoping to work out

what type of clothing the button has come from,

but the markings are so faded, it's almost impossible

to narrow down.

All right? Hiya.

Hi.

Cleo, stop it!

Oh, l don't think you've met.

This is our new Dl, Humphrey Goodman.

This is Cleo Davenport, Shipton's finest on-call firefighter.

Pleased to meet you, Cleo.

Well, coming from the town's finest darts player,

I'll take that. Yes.

Got to say, it did feel good finally crushing the Dartaholics.

R-right.

Lovely to meet you, Cleo. Right.

I was just on my way to pick up Danni from work,

so I thought I'd deliver the initial fire report in person.

Danni's working? Mm. Winslow Stables.

Oh, l remember our first day at St Vincent's.

Stop, you're making me feel old!

Oh.

We've got another fire.

Griffin's Timber Yard. I'll keep you posted. OK.

Ready? Come on. Let's go, let's go, let's go!

Exactly the same MO as the farm.

Any links between here and Vicarage Farm?

Not that l can think of.

Looks like we might have a serial arsonist on our hands.

Look at that! Mind the ants.

Looks like they're having a party.

Oh, uh... Are you the owner?

Ow! Yeah.

Susie Griffin, yeah.

Lucky they didn't burn the whole place down.

Can you think of any reason at all why someone might want to do this?

No disgruntled employees or clients?

Er, no, not that l know of.

There was another fire in the early hours.

At Vicarage Farm, I heard.

Do you know Lucas Fairly?

Yeah, l do. Not a fan?

He's got a reputation, is all. What kind of reputation?

Well, you're better off asking his ex-employees about that.

I'm sure Lucas will worm his way out of it.

He always does.

There's no smoke without fire, if you ask me.

Just...

Hi, Margo.

"No smoke without fire."

Certainly isn't.

Yeah, we're on our way back.

OK, we've looked into all ex-employees at Vicarage Farm.

It seems Lucas Fairly is a bit touchy-feely

with his female employees.

The only one to report anything, though,

is a seasonal worker by the name of Jess Owens,

who left abruptly one month in.

Didn't press charges in the end.

And do we know where Jess Owens is now?

Er, the Darran Mountains in Fiordland National Park.

Isn't that, erm, New Zealand?

Oh! Smart, Detective.

She went about a year ago, not been back since,

and obviously not very contactable right now.

All right, any family or friends still in town?

No, she was just passing through, apparently.

OK. Thanks, Margo.

Well, if that's everything...

..I'll be off.

I've got an appointment with a chicken Kiev.

Goodnight. Right. Goodnight.

Gosh, home time.

I'm going to stay a bit longer.

I'm still trying to find a match for this button.

Well, I could stay and give you a hand.

Thanks.

I didn't know you played darts.

Yeah. Captain of the Kitty Kats.

That's how I know Cleo. She's on my team.

Oh, right.

I used to play a bit of darts myself.

Really? Oh, yes.

In fact, they used to call me the...

...the Eric Bristow of Saint Marie.

OK.

Prove it.

What?

Prove it.

OK.

Ah! Oh! Close.

Yeah, well, I'm a bit rusty.

Whatever you say, Eric!

Excuse me.

Round two.

Round two.

We're going to need more hose!

Statement all done, sir. Thank you, Sergeant.

Humphrey. Archie.

Sorry, er, about your...

Wine cellar. Thank you.

Some of our best vintage in there.

Such a waste.

Yes. Um... Any reason why someone

might want to burn down your wine cellar?

Upset anyone recently?

You think it could be arson? Yes, I do.

That would still be covered by the insurance, though, right?

Well, that's a matter for your insurers.

Excuse me.

Is that a pyjama top, sir?

What?

Oh, yes, so it is.

It was dark when I got dressed.

Margo, can we have a look at Archie Hughes's insurance records, please?

Yeah. Thank you.

Here you go.

Oh, er, yeah, thanks, Kelby.

Life-saver.

You suspect Archie?

Is that a pyjama...?

Top? Yes. Just due diligence, really.

Something he said. It's probably nothing.

So...

So far, we have three fires,

all approximately 12 hours apart at three different locations.

But what is the connection and why the word "pig"?

Why three pigs?

I'll huff and I'll puff and I'll blow your house down.

What was that?

Oh, just when you were saying three pigs,

reminded me of the story.

Margo, you're a genius!

Well, it has been said before.

Course! Esther, The Three Little Pigs.

This is what the arsonist is trying to tell us.

I think you might be clutching at...

Straw? Exactly.

Look, the hay barn is straw.

The timber yard is sticks.

And the wine cellar is bricks.

OK.

Let's just say you're right for a minute.

Why a children's story?

That's what we need to find out.

Back in a minute.

Where's he off to?

I've given up trying to understand the inner workings of the man.

Huh! Right.

Whilst Wee Willie Winkie is running through the town...

Who?

Oh, never mind.

Can you look for any connection between our three...

...victims?

We already know that Susie Griffin and Lucas Fairly have crossed paths.

Any clubs they might all belong to, any events they've all attended,

any employees or friends they have in common, that sort of thing.

On it.

Margo, can you contact Archie Hughes's bank?

I'll collate the financial records for our three victims.

We might find something there if we cross-reference them.

Shipton Police Station.

Oh, hi, Floella.

Let me just see who's available.

Floella Jones has just had a break-in at her boat shed.

That's it. Another load here, if you can.

Took your time, Didn't you?

20 minutes. Came as quick as I could.

Oh, never you mind that. Someone's broken into my shed !

Anything missing? I ain't looked yet.

They might still be in there.

OK, well, l doubt it, but...

...you did the right thing in waiting.

What?! What, what, what?

Nothing. Oh. l ...

Coast is clear. Oh.

So...

Notice anything missing?

I'll have to do an inventory.

An inventory?

How long is that going to take?

Got somewhere to be?

Let me get on with it, then.

Right. One.

OK. Tell you what, I'll have a look around.

64...

Then, one day, a big, bad wolf

came walking along the road.

He saw the first little pig in his straw house.

With an evil glint in his eye,

he knocked on the first little pig's door...

"Little pig..."

Oh. Super.

I thought I'd swing by and see how you're getting on with these fires.

"Not by the hair on my chinny chin-chin!"

Erm... Nap time, is it?

S-sorry.

Noise-cancelling.

I didn't hear you. Sorry, what was that?

I asked if it was nap time.

Oh! No.

I can see why you might think that.

I think better with my eyes closed sometimes.

It's all about sensory deprivation.

And the children's story and the pyjamas,

they help you think better too, do they?

Oh, right! Yes.

Er, no. Well, yes.

The children's story is actually relevant

to the case, ma'am.

You see, our victims are pigs, and, erm...

Sorry, our victims are pigs?

Well, not actual pigs.

Metaphorical pigs.

Right.

Esther, perhaps you can brief me in private?

Er, yes, sure.

Oh, those, er, insurance docs came through.

Oh, yes. Great. Thanks, Margo. Good.

Could you call Archie, ask him to come in, please?

With pleasure.

So how are you finding things here?

Yeah. Good.

And our new DI?

He's...growing on me.

I can see why you might be attached to this place.

It's...it's got a certain old charm to it,

but it is stuck in the past.

You're a good detective, Esther.

I magine what you could achieve with all the modern technology

and support HO could offer you.

What do you mean?

I want to bring you over to the hub.

I think you'd make a great addition to the team.

Not just swinging by, then.

Well, swinging by in a purposeful way.

There'd be a promotion in it for you, too.

Oh, right, erm...

PC Hartford.

Oh. Mm.

Are you choking?

He's definitely choking.

Hold still.

Yeah? Yes, thanks. OK. I'd better go.

Esther, think about what I said. Yeah.

Can the earth just open up and swallow me whole?

Oh...

lt wasn't that bad.

The woman I love just performed the Heimlich on me.

Love or lust?

Sometimes it's hard to tell the difference.

Right, don't you go telling the others, all right?

What, that you've got the hots for the Chief Superintendent?

No, don't worry.

Your secret's safe with me.

Now go and get yourself cleaned up.

Thanks, Sarge.

Right, we're in, er...

we're in. . .we're in here.

I hope I'm not under arrest.

Er, no. No, no.

I just wanted to check a few things with you.

Yeah. Fire away.

Speaking of which, how is the wine cellar?

Oh. "Fire away" - ha. Yeah.

Mostly a great big pile of ash now.

Sorry about that.

Well, luckily, my stock is spread over the other cellars, mostly.

Oh? How many do you have? Five.

Well, four now.

Five. Impressive.

Still, a big insurance claim, I suppose.

I guess so.

Archie...

...is there anything I should know?

Anything you want to get off your chest, perhaps?

Uh, no, I don't think so.

You know, it's best to be honest up front.

Yeah. Right. Better for everyone involved.

OK?

Archie...

... I know.

You know?

Mm-hm.

Oh.

OK, look, I'm...

I'm sorry.

I was wrong. Shouldn't have done it.

Right...

Well, we're all capable of making bad decisions

when we're under pressure.

Thank you.

that's very understanding of you.

So you're ready to make a full statement, then?

Statement? For...for a kiss? A what?

Well, look, I know it was wrong of me.

I'm sorry, I'm confused. What kiss? Sorry, Didn't Martha tell you?

Martha? Look...

You said you knew. About the insurance. The insurance?

You doubled your insurance two days ago.

You kissed...you kissed Martha?

No, no. No, she slapped me. Nothing happened.

Humphrey, I'm sorry.

What's going on? I'm not entirely sure,

but I think it's best if you take over, Sergeant,

before I do something I may regret! Humphrey, listen...

Oh, my grandad used to collect these.

Bits of history, they are.

You think of all the conversations had over a pint of beer.

Lives shared, stories told...

Yeah, must be worth something.

You can't put a value on stories passed down!

Oh, I know you all like to do it on Facepad these days.

But when I were a lass, it were all done verbal, like.

Folk...folk...

Well, we still like to chat over a pint every now and then, too.

Ha !

Well, erm...

...anything missing?

Hard to say.

But l thought... Didn't you do an inventory?

I'm not a bloody oMac!

OMac?

Oh, iMac.

As I said.

Erm, OK.

Let me know if you do notice anything missing.

Right, yeah.

All right? Yeah.

OK.

See you, Flo. Oh, yeah. Cheerio! Cheerio.

You all right, sir? Yes, yes. Good.

Fine, great. Erm...

So where are we up to?

Archie Hughes has increased the insurance on his business

due to winning several awards for his wine recently.

And his whereabouts for the fires?

He was in London on business at the time of the first two fires,

but no solid alibi for the third, just asleep in bed.

But l'm struggling to find a motive.

And no leads on the button still? Nope.

Well, this day couldn't get any better.

Isn't this the bit where you tell us we're missing something?

Sorry?

We've missed something.

What is the arsonist trying to tell us?

If our victims are the three little pigs,

then who would want to blow their houses down?

And why?

Who is the Big Bad Woff?

That was very good.

Yes, it was. Thanks. I've been practising.

I'm going to go see Cleo,

see if the latest fire report's ready.

Maybe that can shed some light on things.

Y-Yes, OK.

Bye.

OK, Margo,

there has to be a connection between the three victims.

Nothing makes sense without that. There must be a connection.

So let's trawl through the backgrounds again.

I'm on a cake break.

What, is...is that a thing?

Since I gave up cigarettes, yeah!

Right. Yes, of course. Yes.

Well, I'll make a start, and you jump in when you're ready.

Right you are.

Yes.

Well, I'll be damned. They were after my paint?

Mm-hm.

And a can of petrol, by the looks of it.

CCTV caught 'em walking away.

Oh! Do you recognise 'em?

What, that dark, blurry figure?

Worth an ask.

Petrol. Petrol.

Uh, excuse me a sec, Flo.

Mm?

Hey. J... J... M...

Uh...

Uh, yes. Hello.

Sir.

Kelby, everything all right?

What colour did they use to paint the "pig" graffiti?

Blue.

Would you say it was a royal blue?

Uh, yes. Yes, I would. Yes.

The break-in at Flo's.

A pot of royal blue paint was stolen, as well as a can of petrol.

l thought maybe it could be related to the fires.

It'd be odd if it wasn't.

Which means we're looking for the person who broke into the boat shed.

I've got an image of the suspect. Bit blurry, but sent it to IT,

see if we can enhance it.

Great. Good work, Kelby. Sir.

Oh, hello. l just wondered if you had the fire report ready.

Oh, great minds. I was just about to drop it off.

Do you want to come in? Yeah. Thanks.

You're a star. Thank you.

Well, I don't know how much help it's going to be,

though, I'm afraid.

Large traces of petrol found at each location,

so definitely arson,

but I'm still none the wiser as to who or why.

No, us neither.

Mum. I can't find my bag.

Oh.

Hi. Hi, Danni.

It's on the hook.

Honestly, she'd lose her head if it wasn't screwed on.

You all right?

Oh, yeah. Zoe's the same.

Anyway, thanks for this.

I best get back. See you.

Yeah, I'm really sorry to burst in on you like this.

l heard about your wine cellar.

Yeah, yeah, yeah.

Oh...

It shouldn't disrupt your deliveries, though.

I'm really busy, Archie.

I know, and I'm sorry.

Please stop apologising.

Yeah, sorry.

I just want to apologise, and I can see how that might sound

like a bit of a hollow gesture, but...

You betrayed our friendship and jeopardised our partnership.

I know.

And I'll go if you want, but please let me explain.

OK, fine. Five minutes.

Five minutes.

Hi, guys.

Right, um...

This isn't an excuse, but when you broke off our engagement,

I was devastated.

And then you came back into my life,

and I realised I'd never stopped loving you.

And you were always the one for me, Mots,

and I wish I felt differently. I do.

And it was selfish of me to put you in such a difficult situation.

I was wrong.

it's not enough to love someone.

You have to want the same things,

be in the same place. Metaphorically, I mean.

You...you both have to feel the same way

and to be honest with each other about that.

And I accept that you might not feel the same way about me

as I do you. Unless you're hiding it really well?

Just checking.

But seriously...

..this partnership,

your friendship,

it'd mean the world to me,

and it would be my biggest regret if I've...

.. if I've ruined that.

Can I ask your forgiveness now?

Yes, you may.

Mots, please forgive me.

Yes, you're forgiven.

Oh, I might have put my foot in it with Humphrey.

What? Crossed wires.

I didn't realise he didn't know about the whole...

.. kiss attempt, slap thing.

Archie!

Why didn't you tell him?

Because l hadn't got around to it.

I need to go and talk to him.

Well, uh, do you want...?

Do you want me to come?

No! But I ...

This is my mess coming back to bite me on the behind.

God, l hate it when Mum's right!

Look, it's still pretty blurry.

It's definitely a woman.

Or a slim man.

I think I know who it is.

From all the way over there?

What? The arsonist?

I'm not sure, but...

Well, maybe this will help.

Yeah. l managed to track down some CCTV footage of the suspect

that broke into Flo's boat shed.

To steal paint and petrol.

It's Danni Davenport.

Cleo's daughter?

The silver button I found?

I've just seen it.

Hi.

She had a silver button missing from her dungarees.

They were identical.

Hang on.

Yes.

Look at this on Lucas Fairly's bank statements. Here.

Winslow Stables. That's where Danni works.

They must buy their hay from Lucas.

And Danni goes kayaking at the Point,

so she must pass by Flo's boat shed all the time.

But why would she set these fires?

I don't know about the other two, but we all know Fairly's reputation.

And on the morning after the fire,

I noticed fresh scratches on his arm.

Wrestling with a fence post.

Maybe he tried to assault Danni.

It could be how she lost the button, too.

Yes, but if she did set the fire at Vicarage Farm

then she must have done the other two.

Wait, Didn't Cleo say she was picking up Danni from work

when the second fire broke out? Giving her an alibi.

Check with the stables. Check she was actually there.

Oh...

Oh, and see the last time she visited Vicarage Farm.

I really hope I'm wrong.

Oh, hi. This is Shipton Police Station.

What about our other two victims?

Our other two victims, the timber yard and the wine cellar.

Are they linked in any way?

Nothing on the searches.

Because all three fires must have been set by the same person.

Cheers, mate. Yeah, brilliant.

Danni Davenport was at the stables all afternoon.

They sign in and sign out.

She was definitely there when the second fire was started.

Airtight alibi.

So I was wrong. Although she was at Vicarage Farm

the day before the fire, picking up hay bales for the stables.

There's nothing new in the fire report either.

Traces of petrol, clearly the same perpetrator, the same MO,

but other than that... Yes.

Unless...

What?

Excuse me.

The lab report might have picked up something

the fire investigators did not.

I don't know. I don't know.

But right now, I'll take anything.

Come on.

Ah.

Huh.

What?

Triglycerides.

That's, um...

Vegetable oil.

Yes, I thought so.

What? I'm a genius.

Though you wouldn't exactly describe its presence at the scene

as being obscure.

Yet it's noted in the lab test, but not in the fire report.

Why?

Why would Cleo leave triglycerides out?

I guess vegetable oil is a common household item.

She might not have thought it was relevant.

Ants' party.

What? Ants!

Do you remember the ants at the timber yard fire?

Lots of them. Yeah.

Well, they would have been attracted to the oil.

They would have been attracted to the oil.

Back in a minute.

Not this time!

I'm coming with you!

What is he doing?

There's a fine line between genius and insanity.

Come on.

Someone showed me how to do this once.

I think I've remembered it right.

So what do we do?

Now...

...we wait.

Would you like to talk about what happened between you and Archie?

How much did you hear?

Enough.

Huh.

Well...

I mean, nothing actually happened.

Certainly nothing for me to get upset about.

M-Martha stopped him trying to kiss her.

So...

So nothing.

I just...

I ...

I don't know why she didn't tell me.

Maybe she will.

In her own time.

It just feels like we're a bit distant at the moment.

I thought the IVF would bring us closer together, but...

You know, facing adversity, what doesn't kill you and all that.

I didn't know about the IVF.

I'm sorry.

Thanks.

For what it's worth,

I've got friends that have been through it.

It's tough.

Yeah.

Puts a strain on anyone's relationship,

but at least you're facing it together.

Except we're not. Not any more.

It's like we just can't find each other.

Now Martha's decided she doesn't even want children.

How do you feel about that?

Fine.

Really?

Yeah, I just... I just want to support Martha.

Be there for her.

You can't just disregard your own feelings.

That's no help to anyone.

You'll figure it out.

I'm sure.

Yeah.

Yep.

Humphrey?

Humphrey.

Don't suppose you've seen Humphrey, have you?

Never mind.

You're right.

I should have told him.

What a mess.

Sir, this is ridiculous.

I'd keep a safe distance if I were you.

What, from the scary cardboard?

Two hours, ten minutes.

Just enough time to set a delayed ignition device,

graffiti "pig" on the wall and get back in time

to give yourself an airtight alibi.

So you do think Danni is our arsonist, then?

Well, yes...

...and no.

I think you were right about Danni and Lucas.

On the day before the fire,

we know that Danni was collecting hay bales from Vicarage Farm.

All right, gorgeous?

My name's Danni.

Get off me! I think it was here, sadly...

No, don't touch me! All right. OK.

...that Lucas likely attacked Danni.

The button coming off in the struggle.

Get off me!

Pig.

Exactly.

On the night of the fire, I think Danni broke into

Floella's boat shed and stole the paint and petrol.

She then headed back to the hay barn at Vicarage Farm

to teach Lucas Fairly a lesson.

She wanted to leave him a very clear message.

But why did she start the other two fires?

I don't think she did.

I thought she had when I first thought of this experiment.

I was trying to find a way to break her alibi,

but then two things struck me.

Which are?

Firstly, if we're right about what happened at Vicarage Farm

and that Danni started the fires there, which I think we are,

then she had no reason whatsoever to start the other fires.

And the second?

The person who showed me this trick...

...was a firefighter.

It's a training exercise.

I think Cleo arrived home to find Danni distraught,

perhaps trying to dispose of any evidence.

And either Cleo worked out what had happened...

What happened? ..or Danni told her.

Danni must have begged her mum, begged her mum not to do anything,

not to go to the police, because if she did,

she would also have to confess to starting the fire.

Cleo must have been desperate.

Desperate. Desperate, because she'd know full well

that there was every chance that her daughter

would be caught and charged with arson.

So you're saying that Cleo set the other two fires?

But Cleo would never.

She's a firefighter.

And a mum that would do anything to protect her daughter.

Cleo knew, though,

that if she could make it look like a serial arsonist,

then she would draw the focus away from the first fire,

and most importantly, draw the focus away from Danni.

I mean, the pattern was already set.

Burnt straw and the word "pig" scrawled on the tractor.

All Cleo needed to add was sticks and bricks,

and we'd be looking for the Big Bad Wolf. And...

...by using vegetable oil,

Cleo was even smart enough to make sure she was at the police station

when the report of the second fire came in.

I'll sort it out, OK? Don't tell anyone.

OK.

During her training, Cleo would learn

that if you soak a rag in vegetable oil

and place it inside a container

then the oil undergoes a chemical process known as oxidation,

that releases energy in the form of heat when exposed to air.

Meaning it will self-combust after a certain amount of time.

She chose Susie Griffin's wood yard for sticks

and Archie's wine cellar for bricks.

See, I think she selected two targets

that she knew would be empty,

so there was no danger of anyone getting hurt.

Now, the oil allowed her to be far away when the fire started.

And just as importantly,

it would send us off on a wild-goose chase

and away from her daughter.

I'm sorry.

I know she's your friend.

If you'd rather not come,

I can do the next bit on my own. No.

No, l'll come.

I'm sorry, Cleo.

You know, don't you?

I'm going to need to talk to Danni, too.

No, no.

I did it. It was me. I set all three fires.

I take full responsibility. Look, I'm sorry...

Do you have someone in your life that you love more than anything?

I do. Yes. And you're willing to throw yourself

in front of a bus to save their life? Yes.

Well, we all have versions of the truth.

Stories that we tell to protect the ones that we love.

I'm telling the truth.

My truth.

I'm not going to change a word of it.

I set all three fires.

I don't think handcuffs are necessary. Come on.

Mum!

No. Please don't.

Sh!

There's a lasagne in the fridge

and there's money in the pot if you need it, OK?

I'll call you when I've got a chance.

Love you.

I love you, too, sweetheart.

More than anything.

Yeah. Good idea.

I'll make us a cup of tea.

Come on, Danni.

Thanks.

You know my daughter, Zoe?

She's 15 now.

And l'd do anything to keep her safe.

And it makes me sick to my stomach,

the thought of anyone hurting her.

I know it's not easy...

...worrying if you'll be believed,

so l would never judge you, Danni,

whatever you decide to do.

But if Lucas Fairly did do something to you,

then he should be held accountable before he hurts anyone else.

And if you did want to tell the truth,

l'm sure what happened to you will be taken into account.

Now, it's up to you...

...but l'll be at the station till late this evening.

Just in case.

Evening.

I thought we could put some of these tankards to use.

That one there belonged to my gramps.

Cantankerous old git.

But get a couple of ales in him, he'd light up.

Start telling stories about his time on the ships.

There was this one time,

he saw a fin on the horizon.

He got his rod, he cast off.

Damned thing ate the whole lot.

it's true! Wow!

it's really true.

These sharks, you know, you've got to be careful.

Yeah. Yeah.

♪ This time, as one, we'll find which way to go

♪ Now come and meet me

♪ On the sunny road. ♪

Everything all right?

Yeah.

No.

I don't know.

If you're worried about the Archie thing, then I know.

It's OK.

I know that you know, but it shouldn't be OK.

You know? How?

Archie told me.

Oh, right.

You've seen him today, then?

He came to apologise.

Oh.

Oh, good.

I came home to talk to you about it, but you weren't here.

And l didn't want to bother you at work.

Sorry.

We've just arrested Cleo Davenport for those fires.

The firefighter? Yeah.

All for her daughter.

Incredible, really,

what a parent will do to protect their child.

It's what you want, isn't it?

To be a parent.

No.

For once, l need you to stop being nice,

stop telling me what you think I want to hear.

Once, just once,

tell me the truth.

It's not a switch I can turn off.

I've tried. I... I've tried.

I can't. I'm sorry.

Now, I want to tell you that I've come to terms with it,

that I'm happy, that it doesn't matter.

But you're right, it's not how I really feel.

I might be able to one day, I don't know,

but right now, it's...

...I can't.

And I know that hurts you and it hurts me, too.

Thank you.

What for?

For being honest.

But l can't marry you like this. What?

How can l ever believe you're happy?

That you won't come to resent me? Wh...?

I'm scared l'm not enough. What?

What happens if in two, five, ten years' time

you still want kids? What then?

Then we...we...we figure it out together.

What? You make do and settle for less just to make me happy?

No... l can't do this.

This will always eat away at us. No.

I can't do it to you.

And l can't do it to myseff.

No, please, don't.

Sorry.

I'm so sorry.

You've got to speak to him. It's better I don't.

What have I missed? Burglary.

Hayley, we know you were at Lucy's house last night. But I wasn't!

We still can't charge her, because she was in our cells

when the burglary supposedly happened.

Are we pretending you don't love him?

He'll meet someone and have the future he deserves.

Word on the police grapevine is that the inspector made inquiries

about returning to the Met.

Were you going to tell me, or just disappear?

How am I supposed to be here if I'm not with Martha?

Seeing her every day!
