So we'll do that ECG in 30 minutes?

Okay.

- Nurses' station. - Do you know what?

Even if you hadn't have told me, I would have guessed,

'cause you have the bearing of a dancer.

You see where I come from,

swimming pools are for swimming in.

I just spoke to your Mum, she's on the way,

it's okay.

- See you tomorrow, love. - Bye, sweetie, take care.

You too.

Hello?

Please.

Please.

Please leave me alone, please, please.

Help me!

Hi, Rob.

What we got?

Not really sure, boss.

What I do know, though, is it's weird.

So then there's no sign of any kind

of physical struggle at all?

With herself, maybe, with anyone else, no.

- Luke. - Staffe.

Is that a nurse's uniform?

ID in her bag says Sofie Churna, 24,

I reckon she'd just come from the hospital.

A good deed, any suggestions?

I'm guessing some sort of seizure

or respiratory paralysis, so death by asphyxiation,

it's the color, the eyes, the spittle.

- Seizure caused by? - Don't know,

I've not seen anything like this

outside photos in a textbook.

- Photos of what? - Sarin death.

- Serious? - I'm not saying

that's what we have here,

because the commuter who found her is fine,

he's at the station, Staffe, as are we.

Well, so far.

So not an airborne nerve agent,

but something mimicking the effects, yeah, maybe.

And definitely not natural causes?

This is anything but natural.

So this is her outside the station

and then CCTV from inside.

There's no one anywhere near her.

Hm.

Spool forward, can you, Ray?

Yeah, sure, there we go, hm.

She looks barking.

As illuminatingly intensive as your perspective is, Rob,

it doesn't quite chime with the fact,

that an hour before, she was working

perfectly normally at the hospital.

Can you give me the platform again?

Sure.

- There. - Where?

Do you see?

I mean, she thinks there's someone behind her.

So she's hallucinating?

Maybe she took something just before she left work?

Yeah, like a recreational drug,

- she had a bad reaction to? - Hm.

Have we found her next of kin?

Her sister's expecting us,

she's waiting with Sofie's little girl.

- What happened? - We're not entirely sure.

Right now, Mr. Balden, we're just waiting

for the post mortem to come back.

What am I going to tell my parents?

Our father, he begged us not to come here,

told us it was dangerous.

Sofie only came, because I talked her into it.

What am I going to tell her?

You and Sofie were together?

Well, it's been a bit

on and off last few months.

- And why was that? - She wanted a better life.

Kat, not now, please.

Was that her choice or yours?

Hers.

And why was that, do you think?

The gambling, the crazy jealousy?

Please.

And was there someone to be jealous of?

She said no,

but she would, wouldn't she?

And did you know of anyone else?

No.

She had been acting weird recently though,

you have to admit that, like,

well, she was away with the fairies,

just acted like she was always

thinking about something else.

And where were you the last 24 hours, Mr. Balden?

I was at work

and then I was at a mate's

and I kipped there for the night.

I could never.

Do you mind if we take a quick look around?

Thanks.

Don't tell 'em anything.

How much do nurses earn?

Factoring in over time, London rents

and paying off student loans, probably 27 pence an hour.

Did either of you know she had that

in her bedroom drawer?

No idea.

Thank you.

So, how does an ostensibly skint young woman

acquire two, three grand in cash?

The stock answer would be stripping or escorting.

That would explain why her boyfriend

thought there was somebody else.

Any disagreements with anyone recently?

A patient who got aggressive?

A drunk who made threats against her?

No, really, she was just brilliant with the patients,

even the lairy ones, she always managed

to calm them down with a joke or, everybody loved her.

Was she seeing anyone?

What, in between 12-hour shifts, the studying

and looking after her daughter, you mean?

So, no.

Well, she certainly never mentioned anyone to me

and I think she would have.

What was she studying for?

There's a series of courses you can take,

if you want to increase your wage band,

she was working all hours to pass those.

How was she doing that?

I mean, how was she keeping going?

I don't know.

Smita, we are trying to help her,

trying to make sense of what went wrong,

so if she,

if she was taking something,

that might really help us understand why she died.

Look, I genuinely don't know if she was,

but a few weeks back, I caught her stealing some meds,

opiates mainly, Tramadol and Fentanyl.

Right, do you know what for?

She wouldn't say, she was incredibly ashamed and upset,

I'm guessing she was selling them.

Did you report it?

She swore it was the first time

and that it would never happen again,

so no, I didn't report her,

because she was my friend,

because she was the best nurse I ever worked with.

Mummy?

We're doing door to doors,

but no eye witnesses or anything so far.

Alright, how's the little girl?

Not so good.

Okay, well just make safeguarding her a priority.

Yeah, will do.

Now a couple of other little tickles for you,

some of the dates her sister babysat

don't match with Sofie's work timetable.

Okay, so she wasn't at the hospital?

- Not on shift, no. - That's interesting.

Now we had multiple calls on her mobile

to and from an unregistered number

and also just heard from Forensics,

in her bathroom taken during their search,

we have small trace of blood present,

which don't match any of Sofie's family or boyfriend.

Right, have you spoken to her sister?

She says she has no idea who's it could be.

And you believed her?

I don't know, maybe.

Anyway, I've asked for a national check,

so we should have a result tomorrow.

Okay, cool, good stuff, thank you, Rob.

Why risk capture trying to enter the home

of the person you've just murdered?

Unless there's evidence in the flat

linking him or her to the victim,

then it's just a calculated risk.

I think it's more likely

it was someone looking for the money,

someone who knew what she'd been doing,

someone who knew there was a spare key

on the back of the door.

Yeah, okay, that makes sense.

And this just came through from Toxicology,

presence of unusual chemicals found within sputum and vomit,

- high levels of physostigmine. - It's an alkaloid.

Okay, pretend for a second

we're not experts on alkaloids.

Quantities like these would cause

rapid contraction of the muscles in the heart, the lungs,

the diaphragm to the point of rigid paralysis

and then death.

Well, how did it get inside her?

Was it found in the alveoli or bloodstream?

It says just in the vomit, I think.

Okay,

physostigmine was produced a chemical process,

in this case, I'd guess digestion.

- She ate it. - Correct.

Okay, is there anything unusual in the stomach?

Well,

this.

Physostigmine venenosum, not a Harry potter spell,

no, nothing?

Yeah, fair enough, it's the Latin name for this,

it's Calabar beans, seed of a obscure,

but highly toxic West African climbing vine

and effectively our murder weapon.

Now Dr. Paul's still waiting for brain tissue samples,

but he believes this is the cause of death,

several seeds like this consumed within her last meal,

which was a salad with the poison released

upon chewing these seeds causing profound hallucinations

followed by total respiratory paralysis.

Jesus, it says here it has a history

in ritualistic killing, is that what we're looking at?

I mean, possibly, but then you'd expect

other stuff to be found at the scene, you know,

like just the body to be doctored post mortem,

just more of a show.

Should we be checking the Russian connections?

Yeah, yeah, I think we have to,

considering Sofie's nationality and the MO.

- Guv. - This seed was ingested

less than 90 minutes before she died,

which means during her last shift at the hospital.

Presumably it's just gone into the waste

along with everyone else's lunches,

but just find out where she got the salad,

where she ate it, if anyone else has been taken ill.

- Sure. - And Rob,

CCTV from the hospital,

everything you can find for the last 48 hours.

On it, Guv.

And listen, this is a rare

and illegal to import seed

and we have evidence that the killer had access

to more than just a few of them,

'cause look, these three were found

still undigested in her stomach,

there can't be that many places,

where you can get hold of a batch of these,

so let's make that work for us.

- Shoplifting? - Yeah, PS4 games

and uniform couldn't get hold of his Mum apparently,

so then he told them that you're his uncle,

so they brought him up here.

Hey,

with me.

Why weren't you at school?

Oh, really, yeah?

Dismissive shrug's for your Mum, it's not for me,

- we're meant to be mates. - Meant to be.

Okay.

Look, I'm sorry I haven't been around more,

but stealing stuff and bunking off school,

that's not me, mate,

it's not you either, is it?

No.

So what's wrong, what is it?

Is there an issue at school?

Well, what's up then?

Have I ever not provided for you?

Have you ever not had lovely things

at birthdays and Christmas?

Have I ever not made it absolutely clear that stealing

is anything other than seriously fucking wrong?

- I'm sorry, it was-- - No, no, no!

You don't need to talk, you sit there and listen.

Don't you dare roll your eyes at me!

Wow, the database has four,

no, five similar cases of poisoning.

When?

In the last 15 years or so.

There was a property developer

found drowned in the Thames in 2004,

then we've got a judge found dead in his office, 2009.

Any Russian connection?

It doesn't look like it, nor was anyone ever arrested.

Well, look what I found on hospital CCTV.

- Do we know who this is? - He never turns around,

but Sofie is out there chatting in private for 11 minutes.

So maybe she was having an affair.

- Hm. - When's this from?

- Two days ago. - And is it

just this one time or?

Not sure, I'll have a further look tomorrow.

- Oh, you off? - Hm, it's the end of the day.

Oh, right, sure.

Listen, I work my tits off in here nine to five,

but I also have a life back at home

and I stopped prioritizing dead people

over it a long time ago.

Sorry, that kind of came out wrong.

You see, me, I have no other life, so.

Hm, night, love.

Night, George.

Thanks.

You know, I should have seen it coming.

- Why? - 'Cause he's been

getting in trouble at school, answering back.

He had a fight with one of his best friends last week.

- He's changing. - Yeah,

I mean, that's what kids do though, isn't it?

He's nearly 13.

Jesus, I was a nightmare at his age.

- I know you were. - At least Hal

hasn't stolen your car

and driven it into Mrs. Dench's front garden.

No, small mercies, ey?

What is happening to my lovely little boy?

Come on, Jules, it's a phase, he'll be fine.

Yeah.

- How about you, are you okay? - Yeah, I'm fine, just tired,

juggling a lot with work and Harry and the wedding.

Yeah, all grown up things of which I have no appreciation.

No, you don't,

and another thing, the estate agents are now booked

for next week, you need to find the deeds.

Hm-mm.

- Is Paulo helping out? - Yeah,

- yeah, he's doing his bit. - Hm-mm.

He has got the bar and he's trying to run a business

and to be honest, Harry doesn't exactly

make it easy for him,

he seems to take pleasure in winding him up, so.

- Wind him up, how? - I don't know,

he just pushes his buttons.

I mean, it's a big thing, isn't it, you know?

I mean, he's never known his real Dad

and now suddenly he's got a brand new one

- just foisted on him. - Foisted?

What do you mean foisted?

- He wasn't foisted on him. - Yeah, sorry,

- just bad choice of words. - I introduced him

- really carefully actually. - Yeah, I know--

Yeah, that was really important to me.

- Yeah, sure, absolutely. - Yeah,

he wanted a real family, a Mum and a Dad.

- Jules, it was just-- - So why

would you say that then?

Look, just give me a second,

hang on.

Staffe?

- Guv, it's me. - Yeah?

I've just had a call from the lab

and we've got an ID from the blood

found in Sofie Churna's bathroom.

Okay, sounds good, anyone we--

Come on, grab your stuff,

- we're leaving. - Just hold on one second.

- Where are you going? - It's getting late,

he's tired.

- Well, I'll drive you. - It's alright,

we'll get an Uber.

Harry!

Bye, mate.

Bye.

Guv?

Yeah, sorry, yeah, I'm here.

Right, the DNA is on a missing persons database

and belongs to someone called Adam Miller,

he was reported missing seven years ago

as a 13-year old kid, there was a search, an appeal,

the full works, but he hasn't been heard from since

and was presumed dead.

And now he turns up in Sofie's flat.

- Checking I don't bunk off? - Yeah,

you get a police escort, now you're a rogue man.

You know, I nearly came after you the other night?

Why?

I don't know, you just, you looked worried.

'Cause I thought Mum was gonna kick off even worse,

when we got out of yours.

Did she?

- Actually no. - How about when you got home?

Everything was fine?

Yeah.

Okay.

Okay,

so I will see you on Sunday then

to whip your arse at GTA.

GTA's a one player game, Staffe,

anyway I'm too young to play it.

Yeah, I tell you what you are too young to do,

one, call me Staffe,

and two, whip your Uncle Will's arse

in a real life fight, ey?

- Come here. - Argh!

Sorry, man, I didn't mean to.

I've gotta go.

Hey, wait.

I'll be late!

Hal!

Stop!

Come here.

Show me your arm.

Give me your arm.

It's just a bruise.

Did that happen at school?

No.

At home?

- Was it Mum? - No!

How many times has it happened?

A few times.

- Two, three? - A few times.

Okay,

listen, mate,

I'm gonna make this go away,

Hal, okay?

I want you to know that

and I want you to know for sure

he is never ever ever going to do that to you again, okay.

Please don't tell Mum I told you.

I won't.

- Promise? - I promise,

promise.

I want you to do something for me, okay,

promise me that you will not take one single atom

of one molecule of the blame for this.

Sure.

Come here.

Go on, you'll be late.

I love you, man.

Right, let's get Adam Miller's picture

into all surveillance systems,

go down to response cops and PCSOs

and start with the area around Sofie's flat,

then just fan out from there.

Where are we with Sofie?

So her meal was bought at a sandwich shop

just outside the hospital,

she went there pretty much every day apparently

and because the customer makes up the salad themselves,

the boxes aren't sealed,

meaning there was plenty of opportunity

for somebody to slip something into the container,

when she was getting her cutlery or paying or whatever.

Right, is there any CCTV there?

I'm afraid not, no.

So like you said, the seeds are illegal to import

without a license, which is seldom issued

since a ritual killing case back in 2012.

Now I spoke to the investigating officer

and he said there was a suspect

they were convinced had supplied the plant to the murderer,

so they're just sending through the case summary.

Thank you.

- Guv? - Yeah?

The car from the hospital carpark,

the one that Sofie was sitting in,

it belongs to a consultant surgeon at the hospital,

Mr. Nicholas Kyrlacou.

So sad,

everyone here has been knocked for six by it.

I'm sure, did you know her well, Dr. Kyrlacou?

Mr., I'm a consultant, no, not well.

I met her briefly and of course I was dutiful,

she seemed lovely, ambitious and bright,

incredibly hard working, so it was a dreadful loss,

not just for her family and her daughter of course,

- but also for the NHS. - Hm.

So that was the extent of your relationship?

What do you mean?

Well, the father of Sofie's child

thought she was having an affair

and we were just wondering if it was with you?

God, no, absolutely not, this is, what?

I'm sorry, but I'm a very happily married man,

it's a ridiculous suggestion.

Oh, that's good to hear,

so why was she in your car for eight minutes 22 seconds

on the evening of the 7th?

- In my car? - Yeah,

and then talking with you in the carpark on the 13th?

You chatted for nearly 11 minutes that time.

Oh, yeah, yeah, I do remember.

So as I say, she had done this course I led

and basically she wanted to know

what other courses she could take

to push her pay grade up as quickly as possible.

Right, I see, I see,

I mean, surely she could have found that information

on a website though?

Yeah, I'm sure, but listen, she was away from her family,

a single mother working very long hours,

no other support network,

so I think she wanted a sounding board,

someone to talk to or maybe she saw me

as something of a father figure, I don't know,

but whatever the reason,

I was very happy to give her a few minutes of my time.

Right, right,

I mean, that was very kind of you.

So why did you lie?

Stupid, sorry?

Yes, I knew her with my group.

Okay, I mean, I think that's everything, Dr. Kyrlacou,

oh, Mr. Kyrlacou.

No problem.

- I hope I was helpful. - Absolutely, thank you.

Oh, sorry, one last thing,

where were you the night of her death?

At home with my wife all night.

And she can corroborate that, can she?

- Of course. - Great!

Thank you.

All lies?

Well, I don't actually think they were shagging,

but the rest of it, yeah, complete bollocks.

Hello?

He's a moody teenager,

his mother let him get away with murder for too long,

he needs discipline.

Oh, man.

You are so lucky we're having this conversation

in a public place.

Oh, where would you like it?

Down by the canal again?

You know what?

I don't want it anywhere,

'cause I don't wanna see you ever again.

Ooh, but we put you on the top table.

'Cause I want you to go.

- Where? - Back to Italy.

- That's funny. - No, it's not,

it's not funny.

I want you to leave.

I always knew that you were a little bit,

but this?

This is something, Staffe.

So I'm not unreasonable,

I'm gonna give you money, relocation expenses.

So kind.

10 grand.

It's up to you, if you take it or not,

but one thing that's not up for discussion,

you hurt the people I love most in the world,

so you're leaving.

Oh, well.

Hey!

Hey, come back, asshole!

- Morning. - Staffe.

So, do you think it's the same cause of death

as Sofie Churna?

- At first glance, yeah. - What time was it called in?

7:30 last night.

So why am I only here now?

It was originally logged as an RTA.

Will you give us a minute?

Then the uniformed lad clocked the color of the face,

that there were no injuries, did a bit of due diligence.

Shit, that would put the time of death

only a few hours after we spoke to him.

Right, which would probably mean

he'd already been poisoned, when you did.

Okay, well get the CCTV footage from the carpark.

In fact, just get the whole hospital.

Okay, and we have an ID on our Calabar seed supplier,

his name's Burn Creasy,

he's a expert in rare plants and flora,

we're just trying to get an address for him now.

- Okay, great. - Yeah, go on, Rob.

So, something is happening in two days,

that Kyrlacou was mixed up in.

And I'm guessing they're still going ahead

on the 20th text means still going ahead,

- despite Sofie's death. - It has to be, doesn't it?

I can also now confirm that Kyrlacou's burner

is a match for the unidentified number

dialed out of Sofie's phone the last few weeks.

Excellent, what you were talking about before,

that's great, that means there's a definite connection

between Sofie an Kyrlacou.

Any progress locating Adam Miller?

- Sorry, not yet. - Oh, shit,

we need to find him,

he and Sofie are connected somehow,

we just need to work out how.

Oh, and I have had a call from Smita Williams,

who was her colleague at the ward

and she now remembers Sofie

talking to a uniformed lad one night,

he was there to nick a drink driver or something.

I tracked the officer down and--

Yeah, and he remembers Sofie very well,

says that he got the impression,

that she wanted to report something, but she was too scared,

so he assumed drugs or domestic violence,

tried to press her on it and she shut down.

So the question is

what or who

was scaring her?

DI Wagstaffe.

Chris Panousis, Nick's brother-in-law.

- So sorry for your loss. - Yeah, thanks.

Mrs. Kyrlacou,

I'm DI Wagstaffe, I'm sorry for your loss.

What did you question my husband about?

I don't think this is the best time to be having

- this conversation. - I want to know.

I wanted to ask him about the nature

of his relationship with Sofie Churna.

Did you think they were having an affair?

- Phoebes. - Did you?

I thought it was possible, yes.

Were they?

I don't believe so, no.

Did you?

Yeah,

if not her, then someone.

And why would you think that?

Because the last few months,

I completely lost him,

he wasn't there for me,

he wasn't there for his kids, who he adored.

He said he was at the hospital,

but I knew for sure he wasn't,

he just became a different person.

Well, like I say,

I don't believe they were having a relationship,

but I do think they were caught up in something.

Nick dedicated his life to helping others,

- he was a good man. - Phoebe,

maybe the officer's right,

maybe this isn't the time or the place

to have this conversation.

Maybe we get the identification done

and then we can talk upstairs, hm?

Come on.

So on the off chance, I went through new CCTV footage

of Nick Kyrlacou's carpark space

after he drove off last night

and that's where I picked up Adam Miller.

- This was when? - Be about 10 last night,

he hung around there for an hour or so

and then when he left, I've managed to track him

all the way to jumping the barrier at the tube station

and from there, he comes up at Westbourne Park

and then he walks to the Grand Union Canal

and that's where I've lost him there under the flyover.

Josie.

Hey, my name's Will, I'm just looking for a guy called Adam.

He's not in any trouble,

I just wanna talk to him.

Can we show you a photo, maybe you can, shit!

Oh, God.

Suspect heading northeast on foot.

Out of the way, out of the way!

Adam!

Adam!

We just wanna talk to you.

Adam!

Stop!

Adam!

Adam!

Adam!

Adam!

Staffe.

It's Paulo.

- So, you made a decision? - Yeah,

I think maybe I will go,

she's just more trouble than I think she's worth.

There's one thing though, I want more,

not 10,

I want 25

or I tell the police about a little encounter.

You think about it.

Argh!
