So, Miss Evans,

what were you doing at the car park?

Why won't you answer?

I'm sorry, Sir, I realize it would've been helpful

to mention it before,

but I visited a support group last night,

and Miss Evans was in attendance.

Support group? What kind?

It's...

Urgh, what's he doing here?

I used to work here myself.

Someone I should know?

Douglas Gilmour. Retired DCI.

- Excuse me. - He won't see, I'm afrai...

Have you lost your mind, Calvin?

Sorry, Sir, I told him he can't just barge in.

It's alright, Will, thanks.

Arresting an innocent young woman

in the workplace? It's a disgrace.

And which innocent young woman is this?

Evans, Patience Evans.

Well, she's not under arrest.

She came in voluntarily.

She'll find this whole experience

no less traumatic

for not having been read her rights.

Can I ask why you're so interested

in Patience's welfare, Mr. Gilmour?

- And you are? - Ur, DI Bea Metcalf.

Ah, the fool who got Patience tied up in this nonsense

in the first place.

You didn't answer my question.

I'm her godfather.

Perhaps the closest thing she's got to family.

Sorry, Douglas. We didn't know.

I want her released this minute.

Well, she's free to stop cooperating.

But to be honest, this is starting

to look like a murder inquiry.

And she knows more than she's letting on.

Then at least let me talk to her,

check she's okay, given her neurotype.

- Her neurotype? - Patience is autistic.

That's what I was trying to tell you, Sir.

I'm sorry, Patience.

Mr. Gilmour's here.

He'll be allowed to come and speak to you

if DCI Baxter decides to carry on with our questions.

We really need to know

what you were doing at that car park.

I need you to trust me again. Please, Patience.

Can you say something?

Patience.

Patience.

Was your wife like this?

Like what?

Did she exhibit the same emotional deficit?

Was she cold with Patience

before she decided to leave?

Can you say something?

I understand.

I'm not sure I'd be talking to me either.

I was just looking for a cigar.

Like the one we found at...

the scene of Neil Jamieson's death?

And...

and the one that I saw in the photographs,

from Dr. Clark's clinic.

I knew it would prove a definitive link,

but when I went to the car park,

I couldn't find any traces of it.

So, then I thought that I must be wrong.

And I don't like being wrong.

You're sure there was a cigar

found in Brendan Clark's treatment room?

Yes.

Yes, I am. You can see for yourself.

I will do, Patience. I...

I suppose I'm just wondering

what would make you notice a thing like that?

I used to count Dr. Clark's books,

so I wouldn't have to speak to him.

You know every inch of his shelves.

What makes you think it's significant?

Well, Dr. Clark wasn't a smoker.

How do you know?

Maybe he had one

when you weren't around.

No, I'm hypersensitive to smells.

And...

especially so with tobacco smoke.

Cockscomb.

- You alright? - Why wouldn't I be?

Well, Baxter told me what happened.

She should never have been brought in

for questioning in the first place.

Or maybe she should never have been

listened to when she started

sticking her nose in.

Why didn't she tell us she was autistic?

She's not obliged to.

Well, why didn't you more to the point?

I...I only found out last night.

You still could've said something.

Uh, I wasn't sure if it mattered,

or if it was anyone's business but hers.

Of course, it matters. It makes her

temperamentally unsuitable for this kind of work.

I'm not asking her to put on riot gear,

crack heads on the frontline.

I don't care if she's autistic.

I just care if she's right.

Why's she left it here?

Don't suppose she's been able to face picking it up.

I mean, there's barely been a packet of crisps

opened in here, let alone, uh, someone smoking

a bloody great cigar.

Let me just check the boot.

Jake...

Why didn't this turn up before?

It's a blind spot, Sir.

We had to get this from an office block

overlooking the site.

I asked DC Akbari to go back over all the car park CCTV,

looking for the same person from the same day.

- Is that the money? - Looks that way.

The evidence we've gathered suggests that this individual

may have attended the scene of each man's death

to leave a half-smoked cigar,

which means we have to assume the cases

may be linked in some way.

Alright, uh, I'm gonna set up a major incident team

with you as SIO.

Uh, what do you need?

I'd like Miss Evans on my team

as a civilian investigative assistant.

Do you think that's wise, given what we know?

We wouldn't have a case without her.

Well, I suppose it would improve our diversity stats.

And maybe our clear-up rates.

Alright, but you'll have to clear it with Gilmour first.

Mr. Gilmour.

Come to apologize?

I'm happy to say sorry, if it helps.

Not to me. To her.

- Is she at home? - Afraid not.

I'd invite you in for coffee, but...

But the roasting process produces a known carcinogen,

so I'm told.

Tea would be fine.

You've known Patience her whole life.

Yeah, through all her ups and downs.

Yeah, my goddaughter's been under

one form of psychiatric supervision or another

from a very young age.

Then she was diagnosed early?

No not until she was almost 12.

There was still a lot to learn about girls

and autism in the '90s.

She barely spoke as a child.

That must've been hard for him.

No, you've no idea.

Especially as a single parent in such an unforgiving job.

Is that why he was advised to put her into care?

Maybe.

But there's no way George would agree.

No, he was, uh, he was convinced she wasn't ill, just different.

Yeah, he was determined to keep her at home,

help her to live independently.

He did a good job.

Yeah, with a dollop of luck along the way.

Patience, you alright?

Oh, no, no, no!

Patience, no, no, sorry, sweetheart.

You shouldn't be looking at these.

How did you get them?

- I'm sorry, honey. - Is she alright?

What's a toxicology report?

Yeah, she started to open up after that.

S-so bizarre.

Yeah, sounds macabre, doesn't it?

But George didn't care.

Started bringing files home for her.

You know, he was just glad to see her switched on,

asking questions. - How did she end up at

Criminal Records?

Well, I moved there, uh, to manage a team

after I retired from the force.

You took her on?

Yeah, at George's request.

As an intern at first, she was only 16.

That's hard to imagine.

- Isn't it? - Hmm.

Well, she's, uh...

so conscientious, so...

so inquisitive and curious and...

so determined to understand how everything works.

You're very fond of her.

Yeah.

It's hard not to be.

How did her dad die?

Ah, road traffic accident.

On duty.

And what about her mother?

uh, she left when Patience was six.

Can you help me persuade her

to join my investigation?

Stress may trigger a burnout.

She's an absolute natural, Mr. Gilmour.

I need her on my team.

Two umbrellas?

- Yes, in case one breaks. - Genius.

I'm gonna start carrying two of everything from now on.

I got permission from Baxter

for you to join the major inquiry team.

I work on HOLMES.

It's... it's a temporary assignment.

I've... I've emailed your boss to let him know.

But, why... why would you do that?

- I thought you'd be pleased. - No, I...

uh, uh, it... it's too unpredictable. I...I can't.

I can't. - Alright, alright,

don't freak out, it's...

Sorry, sorry.

I've learned that without my routine

I...I...I can get stressed,

and if I get stressed, then... then I can't cope.

- You don't have to decide now. - No.

Well, I'm gonna be late for my bus.

- I can give you a lift. - No, I'm taking the bus.

It's my routine.

Oh.

You couldn't keep away.

I'm... I'm actually a detective,

and Patience has been helping me with one of my cases,

and now she's cooling off.

Right.

Well, perhaps you need to revisit

what piqued her curiosity in the first place.

- What would that be? - Well...

many autistic people have

what you would call a special interest.

So, mine's mountain bikes,

but I also... collect loyalty cards

from, you know, cafes and coffee shops.

Oh, I don't drink coffee, Inspector.

Oh.

But special interests can be, uh...

they're like a comfort blanket.

They... they can also be an Achilles heel

if they are prioritized at the expense of other needs.

Does Patience have one?

Yeah.

Yeah, she's very into puzzles.

She can...

she can forget to eat or sleep if she has an unsolved one.

I've told you I am getting the bus

because it is my routine.

I'm not here to give you a lift.

Listen, I mustn't get stressed.

I'm... I'm not gonna try and persuade you

to change your mind. I just...

I forgot to say thank you.

The inquiry wouldn't be happening without you.

Of course, we're still some way off

from proving exactly what happened.

I mean, the sums of money are small,

hardly seem worth killing over,

and what's the significance of those cigars?

It's like pieces of the puzzle are missing.

Still... that's for me to worry about.

See ya.

Yeah?

Blimey. Don't you burst into flames

if you're exposed to daylight this early?

- Funny. - It's just not often you're in

before me. - Baxter's badgering me

for an update. Whoever drugged these guys

had to really know what they were doing.

A drop too much of scopolamine

and you risk fatal overdose,

too little and it has almost no effect.

Some kind of chemical expert then?

Or just a cold-hearted sadist.

The Nazis used it as a truth serum.

Bloody hell.

You think our perp's a witch doctor?

Hardly. But...

scopolamine and cigars are both used

in voodoo rituals.

Not round here they're not.

I'm thinking a factfinding mission to Cuba,

all expenses paid. - How about Belize instead?

That brand of cigar you found in Chopra's exhaust...

Cock-something... - Cockscomb?

Yeah, well I did some digging, like you asked.

- The cigars are made in Belize? - No, better than that.

You can only buy them at one place in the city.

Look, here you go.

According to social media,

it's owned by second-generation immigrants

from you know where. - Did you call them?

No, I haven't got round to it yet.

Christ on a bike.

What is it?

From Patience.

Spooky.

How did you know?

Oh, it's like any puzzle, Detective Bea.

The solution lies in looking at it from a different angle.

- Hmm. - Let me show you.

It's like a work of art.

I think visually.

I'm more of a words person, myself.

You may need to explain. - Okay.

Uh, Brugmansia Candida.

It's a natural source of scopolamine.

It's commonly known as Angel's Trumpet

in Latin and South America.

Including Belize, I take it.

So, when I saw the list of countries

where it grows naturally,

I was reminded of a book.

A travel guide to Belize that I saw on the shelves

of Dr. Clark's treatment room.

Was it there when you were a child?

Definitely not.

Then he's traveled there since.

Neal Jamieson's social media.

It was taken at Houston Airport departure lounge

on the 8th of October 2016.

What about Chopra?

Well, I couldn't prove a direction association,

but I did find this.

- Medical records? - Yeah.

He acted as an expert witness for the CPS

a couple of years ago.

It shows that he was inoculated

against hepatitis A, B,

cholera, diphtheria, which are all in line with

the Foreign Office travel advice to...

- Belize. - Yeah.

- I could kiss you. - Don't.

Please don't.

Come on.

Oh, come... come where?

Headquarters. I have calls to make.

No, I've not planned for that.

I need you, Patience.

- DI Metcalf? - Yes.

Thank you for seeing us, Mr. Cooper.

I'm happy to help.

Everyone here very shocked and saddened

when Neal took his own life.

Although it was some time ago now.

But please, follow me.

What is it you do for Curabellum?

I am the director of marketing and events.

My card.

Oh, then you were involved in organizing a conference

on your company's behalf

in the early part of October 2016?

- I was. - Presumably you also attended?

- That's correct. - And Mr. Jamieson too?

I'm not sure, um... quite possibly.

I don't suppose you recall the purpose of the event?

Of course.

To discuss, uh, new treatment

for, uh, psychiatric illness.

We organize them as a platform to market the drugs

we develop for the medical profession.

Can I ask what this is about?

Two men who we believe attended the conference

have died subsequently

in a similar fashion to Mr. Jamieson.

Do you think they killed themselves?

That was the coroner's conclusion.

Although the involvement of a third party

is also a possibility.

Can I ask their names?

I can't disclose those, but I'd like to see

a list of the delegates.

I'll pass on your request to our legal team.

We have data protection requirements, you understand.

How long will that take?

You know what lawyers are like.

Thank you, Mr. Cooper.

Let me know when they're ready to cooperate.

Of course.

Um, is that your real name, Mr. Cooper?

Patience...

No, just the way he speaks is...

You can't say things like that.

It's okay, I'm alright,

I'm used to it.

I got tired of hearing people pronounce it incorrectly,

so, I changed it to the English version.

Okay?

Thank you.

What is it?

I just... I feel like I should recognize him.

From a case you've filed?

Yes, but... his name isn't familiar.

What do we do now?

Tread water for a bit, I guess.

Uh, we have to wait for confirmation.

You're the police.

Can't you just force him

to give you the names?

We could apply for a court order,

but without clear evidence of a crime,

we may not be successful.

It's not like this in crime fiction.

Come on. I'll drive you back.

Oh.

Thank you.

You okay?

You seem distracted.

Quieter than usual.

Are you feeling overwhelmed?

By the police investigation?

How'd you know?

Detective Inspector Metcalf told me.

Oh.

I'm...

it's...

solving crimes isn't... isn't like solving puzzles.

It's...

there are all these rules and... and restrictions.

It's frustrating,

and exhausting.

Yeah, I can imagine.

I need to find out what happened

and solve the case to feel...

to feel certain.

Do you wanna talk about it?

I'm not supposed to.

But would it help?

Now, this is a table showing the clear-up rate...

showing the clear-up rate across the North East

for street robberies and burglaries.

Surprise-surprise, we're in the relegation places.

And Superintendent Gibbs has told me in no uncertain terms

the Chief Constable is not very happy about it.

We need to find a way to boost our...

Do you want me to put you out your misery?

No way.

The criminal classes in York...

I'm gonna crack it.

...covering their tracks, than their counterparts...

Patience says it's just a matter of looking at things

from a different angle.

...CID colleagues in the west of the county

considerably outstrips that of our own.

Now you don't need to be a genius to deduce there might be

something in their methods that we can learn from.

Uh, which is why I've invited DCI Sharma

from the dedicated burglary team in Bradford

for a Zoom call...

I hope you've got a good excuse.

James Cooper, aka Jaime Cobre in his native Spanish.

It was a question of looking at it from a different angle.

And Patience was right. He's on file.

Soliciting sexual services in a public place.

Cautioned first time, fined the next.

No wonder he anglicized his name.

Also found this.

What, prostitution's legal in Belize?

Yeah. San Pedro's a hotspot for sex tourism.

That sounds like the sort of place that

Neal Jamieson would feel right at home.

Exactly what I was thinking.

I'm betting the four of them got involved

in something kinky while they were out there,

and the deaths are in some way connected to that.

So, you think Cooper's our perp?

We need to talk to him again at the very least.

Mm.

Boss?

It's just a cold, I think, but it's a bad one.

Could you, uh, put my out-of-office on?

No, no idea.

Uh...

Next week, maybe.

Look, I've got to go.

Sorry, I forgot you were coming.

I'm...

I'm just very disappointed, Patience.

Look, she was very explicit I shouldn't tell anyone else.

Oh, well, that's alright then.

- I have an autism diagnosis. - So?

So, Patience and me, Inspector,

we're sticklers for the rules.

That's not really the point, Mr. Thompson.

It's a matter of trust.

There's probably no harm done.

Look, we've helped your investigation, Inspector,

not hindered it.

That's what we've came here to explain.

It's the list of delegates from the conference you asked for.

Well, how'd you get that?

I saw Patience

and how distressed she was feeling, so...

I decided to do what a neurotypical would do,

and I bent the rules a little.

Bent the rules?

Yeah. My girlfriend...

she's a hacker.

I'm gonna pretend I didn't hear that.

She hacked into Curabellum's server?

She also hacked into James Cooper's private email.

She found this.

It's confirmation of a charter

from a boat company in San Pedro,

paid for by James Cooper.

There's an insurance declaration,

with the names of his passengers.

Four men in a boat.

- It's inadmissible. - Shows we're on the right track.

Look, there's something else you should know, Inspector.

James Cooper had hacking alert software installed,

so you should assume that he knows you're on to him.

Are we waiting for back-up?

How long did they say?

Six or seven minutes.

Sod that.

Boss...

Bollocks!

Mr. Cooper!

Look at me!

My colleague's on his way to help you.

Just... just stay where you are, Mr. Cooper.

James?

James, look at me, mate.

Look, you... you don't wanna do this, okay?

Don't do this, James.

Alright?

Look at me. Yeah.

James. Jam... no!

Patience Evans, she's with me.

There was no sign of forced entry.

Oh.

You're with me. It doesn't apply.

Pop these on.

Maybe try not to touch anything, just in case.

There you go.

Cooper must've known his assailant...

well enough to let them in.

This is where they blew powder in his face.

While he was rushing to get away.

- Yeah. - Anything I can help with,

Inspector? - Elliot, this is Patience Evans

from the HOLMES team at criminal records.

Patience, this is Elliot Scott, our crime scene manager.

Sorry, Elliot Scott?

That's right.

One T, then two.

Well, it's just your...

surname's a first name,

and your...

first name's a surname.

I...I never thought of it like that.

Um, you should probably tell your team

to swab for micro traces of scopolamine

on the front of the safe, and on the carpet as well.

Who did you say she was again?

Patience Evans from criminal records.

And before you ask, she has a forensic knowledge

of the three deaths associated with this case.

Um, the furniture on the right has been dusted,

but it hasn't on the left.

She's right.

Either someone wiped away their fingerprints, or...

James Cooper has a very lazy cleaner.

Hmm.

So, Cooper survived then?

He's critical, but he's got a pulse.

Get a chance to charge the bastard.

Hmm.

What, you don't fancy him for it?

Not for Chopra, Clark, or Jamieson, no.

Okay, he knew we were onto him. He jumped out of a window.

But the call to his PA and the passport on the floor,

he... he was getting ready to run, Sir.

What about the cigar? Who left it?

Maybe Cooper himself.

I bet we find someone else's DNA.

This death doesn't even fit your pattern.

It wasn't on the fourth day of the month,

and it wasn't a Friday.

Maybe whoever did this knew we were closing in.

It's the preliminary forensics, Sir.

We've taken prints from the scene

that's matched someone on PNC.

Yemaya Vasquez?

Yemaya Vasquez?

She's the cleaner at the Railway Hotel.

She was fingerprinted after Neal Jamieson

was found dead. - A cleaner?

Yeah.

What better way to get close to

your unsuspecting victims?

Uh, you can go as well, Miss Evans.

Okay.

Great. Thank you.

- Yemaya's quit. - Her colleague just told me.

Yeah, the manager doesn't have a contact for her.

She says the cleaning's outsourced.

I got the number for her landlady.

Yemaya told her to call this woman, Maria,

in the event of an emergency.

Right, let's give her a call then.

Hola. Lo siento, no puedo atender su llamada.

Por favor, deje un mensaje.

O si es urgente, llámeme al trabajo en cero uno seis

tres dos nueve seis cero ocho cinco siete.

Anyone at the station speak Spanish?

Pfft.

Well, maybe.

It says to call her on her work phone if it's urgent.

uh, oh, one, six,

three, two, nine, six...

0, eight, five, seven.

It's... it's the number for that café.

Are you Maria?

Who's asking?

Are you Yemaya Vasquez's landlady?

Amongst other things, yes.

Do you know where I can find her?

She flew back to Belize.

Last night.

Mind if I take a look?

Um... hey. Excuse me.

Yemaya, are you in there?

It's the police, Yemaya.

Yemaya?

Hey! Hey!

Yemaya reported her sister missing?

Yes, when she failed to return from a boat trip

in October 2016, I believe, yes.

The same month as the conference.

It would seem so, yes.

Any more details?

Only a girl's first name, Violetta,

and age 17.

And there's this, um, a photo. I'll just send it to you now.

We've a record of Violetta Vasquez

applying for a visa to study in the UK,

um, in March 2016.

Did she take it up?

No, there's no record of exit.

No record of exit at all.

But nothing else on your system?

Perhaps it's not the same girl.

Or perhaps her sister traveled here in her place.

Boss.

I want to apologize. - I'm listening.

I'm sorry I wasn't truthful with you...

about Yemaya.

I thought you were from the immigration authorities.

Should it make a difference?

She was getting ready to fly home.

I wanted to spare her the trouble.

She's wanted for murder.

How could I know?

Uh, she was very quiet,

kept herself to herself.

Can you explain this?

It's an altar.

To Chango.

The fella with the axe?

He's a divinity of fire in the Santeria religion.

He can be invoked to bring revenge on your enemies.

Especially on men who hurt women.

The cigars, are... are they an offering?

To maintain favor, yes.

Do Friday and the number four

mean anything in this context?

Friday is Chango's special day,

and four is his special number.

For the tape, I am showing the suspect

a book of matches from the Railway Hotel.

Can you ask her whose blood it is?

Te pregunta de quién es la sangre.

She's talking then?

The woman from the café, Maria,

she persuaded her to cooperate.

Has she confessed?

To all three, Sir.

And Cooper.

La sangre es de mi hermana.

Encontré de fósforos en el barco donde fue

asesinada por esos médicos ingleses.

She says the blood is Violetta's,

and also she found the matches on the boat

where her sister was killed by the English doctors.

Was the sister a sex worker?

Yemaya says not, Sir.

She insists Violetta was working

as a hostess at the conference,

got propositioned by Cooper

to come along on the boat trip

to serve drinks. That's all.

Sounds a bit naïve.

She was only 17.

Yemaya tried to persuade her not to go, but...

Cooper offered her $500,

and Violetta was saving to study in the UK.

Have we got any proof they killed her?

Just Yemaya's testimony.

She was worried about her sister,

went down to the harbor to wait,

but when the boat came in, just the four men got off.

What, no sign of the girl?

Yemaya searched the boat.

All she found was a book of matches.

So, let me get this straight.

She travels halfway around the world

on her sister's student visa

to find her killers and avenge her,

with this... book of matches as her only clue

to their whereabouts?

I pray to Chango.

Here we go.

Thanks.

Thank you.

How long did Yemaya work at the hotel

before she recognized Jamieson?

Almost a year, she reckons.

- And he confessed to her? - Hmm.

Under the influence of scopolamine.

What, that they killed her sister?

They claimed that they were drinking on a boat.

Got out of hand. - And she tried to fight,

apparently, but there were four of them.

Took turns to rape her.

Jamieson told Yemaya that Cooper pushed Violetta over the side

after it was over to prevent her causing trouble.

The others didn't try to save her.

How did Yemaya track down the others

after she'd killed Jamieson?

Uh, she stole his phone,

found them through a WhatsApp group.

And the money?

She was sending it home to grandma.

How long's she been in there?

About three or four minutes.

I was betting they'd run out of things to say

after 30 seconds.

What did the CPS say about Cooper?

Well, they didn't rule out a prosecution.

What, even though Violetta died overseas?

They can claim jurisdiction if the victim's under 18.

Oh, they're wrapping up.

I'm gonna take her to lunch.

Yep, then we can all go back to normal.

Miss Evans, I'll leave you in the capable hands of DI Metcalf.

You hungry? Canteen should still be open.

What's so great about normal?

Okay.

Can I sit?

Yeah.

It's just this is the best table, it's...

it's not too noisy, and it's not too hot.

Excellent choice.

Thanks.

I don't understand why neurotypicals

like to eat together.

You have to make small talk.

There is that.

I'm not very good at small talk.

You're doing... fine.

It's just the only things that... really interest me are...

forensics and criminology,

but you can't talk about the hypoxic effects

of certain poisons, or the rates of bodily decomposition

whilst you're eating, 'cause neurotypicals don't like...

don't like it.

Sorry.

That's actually why I like puzzles so much.

It gives me something to talk about.

I could talk about your puzzle- solving skills for hours,

Patience.

We wouldn't have caught Yemaya Vasquez

or James Cooper without them.

You really... made me think outside the box.

Nine dot puzzle.

Think outside the box.

Yes.

Well done.
