20x02 - Death of the Small Coppers

[bunniefuu]

- Morning.
- Morning.

Hi, there.

Hello?

Anika, Grady.

Where's Mahesh?

He's supposed to be here by now.

His car's here.

I'll check the summer house.

Aluminum, that's fine, I know that one.

Tin, tin's fine.

Gold.

Oh!

Hey, you, give me back my gold!

Oh no, not you, Mrs. Willis, it's...

Hey, you, give me back my gold.

When was the Ponte Vechhio built?

It first appeared in a
document in 996... ad.

Come on, come on, Leo.

Details, details.

One more.

How small is an atom?

- Very.
- Leo, how small?

Really rather titchy.

- What are you playing at?
- Can we just go?

No, every second counts.

How small is an atom?

.00000001 of a millimeter in diameter.

Okay.

We can do some more on a walk.

Time to make your mom proud.

Victim: Mahesh Sidana.

Head of the local school.

The wife found the body.

He'd been collecting butterflies.

Circulus?

It's an IQ society.

A membership club for people
of high intelligence.

It was founded here in the village.

They use the school during the holidays.

Maybe we should join, sir.

I'm a bit of a legend at pop quizzes.

Unbeatable.

Really?

Circulus exams are a
little more demanding

than a pop quiz, Winter.

Ah.

Well, that's odd.

Someone's lost a butterfly.

Stunning.

I think you'll find the butterfly's
quite attractive, too.

Hey, you two.

All set?

I think so.

You know it's a waste
of time, don't you?

There are those who thought...
who think differently.

Of course, sir.

Test me.

Latin name for small coppers.

Lycaena phlaeas.

And one.

Bye!

Mary's virgin explanation made

Joseph suspect upstairs neighbors.

And why wouldn't they?

Hi... Oh.

You're studying the exam again?

Eddie, will you never learn?

I just did, I have learned.

I've learned so much my
head's gonna explode.

Who in their right mind chooses
to be surrounded by death?

What about Mr. Sidana?

Popped his clogs.

Any idea how he popped them?

An earth auger drill bit powered

through the pericardial cavity

might have had something to do with it.

Pre-porridge.

Paint's still slightly tacky.

Painted pre-porridge presumably.

There's no sign of forced entry.

So, either the doors were unlocked

or the k*ller had a key.

Signs of a struggle.

This might've been useful.

Ethyl acetate.

He was asphyxiated.

It's used in k*lling jars.

That's what you keep butterflies in.

You douse a bit cotton ball
and drop it in there, too.

It kills without marking.

I had no idea you were an expert.

Did it in Biology.

See, it's not just pop quizzes.

Should we call it one-nil to me?

We did the one
where you take a dead frog,

stick electrodes in it
and make his legs kick.

Weird things, butterflies,
according to my fella.

Nature's proof of reincarnation.

Why k*ll someone in the
manner of a caught butterfly?

Notice any thing in particular?

The black edging, copper orange wings.

It's the butterfly from the poster.

A Small Copper, I believe.

One-all?

Welcome to Circulus.

In this, our 20th anniversary year.

In which time our community has come far

and you are all welcome to join us.

Or try to.

General knowledge today,

mathematics and lateral
thinking tomorrow.

Mahesh went collecting in the meadows

and... I was at an editorial meeting.

I edit the local newspaper.

We have an office in Newton Magna.

So what brought you home?

Grady Palmerston rang,
he said that Mahesh

hadn't turned up to invigilate.

Tell me, would your summer
house normally be locked?

Absolutely.

He kept the key with him at all times.

Is there a spare?

At school in his desk, I think.

Your husband wasn't the
only person interested

in butterflies.

We saw a young woman in the village.

Penny Kingdom.

Biology teacher.

She runs a lepidoptery group.

Was your husband a part of that?

No.

He kept his hobby to himself.

Oh, someone shoved them
through the letterbox.

Any idea who?

No.

There has been a campaign.

I guess nobody likes a club who
won't have them as a member.

Was your husband a member?

Yes, a founding member.

So, if this campaign escalated,

your husband might have been a target.

A lot of mint in that room, strange,

- don't you think?
- Not really.

Her husband who was
obsessed with butterflies

but kept his collection
in the summer house.

Mint repels insects.

She's not a fan of insects
or maybe her husband.

Very good, two-one.

We'll need background checks on Mrs.
Sidana

and look into the butterfly
group and Circulus.

I'll take the lepidopterous.

I thought you might.

Local heads.

Who will you get to replace Mahesh?

If I knew that I wouldn't

have asked for the list, Celeste.

Find Luke, it's time he
pulled his finger out.

I'm meant to be at work.

I'm not going to sack you, am I?

- Morning.
- Morning, Luke.

Pint of Grace Ale?

Quite a detective finding me here.

Your directions were good.

Sorry to hear about Mahesh.

Anika told Grady, Grady told his wife,

and Grady and Celeste told the world.

Mr. Sidana was your boss, wasn't he?

I gather he wasn't a member
of your butterfly group?

He liked to trap, k*ll
and pin butterflies.

We believed butterflies are
better alive than dead.

I gather some are missing.

Yeah, some Small Coppers.

They normally thrive I this area,

but this year none, not one.

I think someone's poisoning
the land with pesticides.

And why would someone do that?

Because people in Little Crosby

don't care about the environment.

They're only interested
in someones like you.

Not a fan of Circulus, then?

It's everything I hate.

What it represents.

It's divisive, it's aloof,
it's a clique, it's a cult.

Yeah, but apart from that.

You wouldn't happen to know anything

about anti-Circulus leaflets, would you?

Who else was a member of
your butterfly group?

You said we.

Me and Luke Fawcett, mainly.

He's an English teacher.

Well, was.

He lives in a caravan
in the next meadow.

Was?

Oh, he was sacked last year.

Who by?

Mahesh.

Luke!

Luke, are you in there?

Luke!

I'm looking for Grady Palmerston.

Detective Chief Inspector Barnaby.

I'm Palmerston.

About Mahesh?

Perhaps we can talk outside.

I have an exam to invigilate.

I have a m*rder investigation to pursue.

The word invigilate comes from vigilare,

to watch over.

I can't do that from outside.

Of course.

Silly me.

I'll just have to stop the exam, then.

Do you have any idea why someone might

want to k*ll Mr. Sidana?

Nope.

Mahesh was too ineffectual
to have enemies.

Perhaps he wasn't the ultimate target.

I've seen the leaflets.

Oh, ignorant nonsense.

We're the perfect meritocracy
with a global membership.

The people who wish us to
fail are barely capable

of committing pen to
paper, let alone m*rder.

You see m*rder as a
feat of intelligence,

- do you, Mr. Palmerston?
- I see this one

as irrelevant.

I should look closer
to home if I were you.

Would you now?

Why?

I own the Courier.

I brought Anika out of
premature retirement

Mahesh was... spitting about it.

Preferred his wife at home cooking.

Are you suggesting Anika
Sidana k*lled her husband?

I'm saying Mahesh was dull
enough to drive anyone crazy.

A minute ago he was too
ineffectual to have enemies.

Are we done?

There was a man pacing
nervously outside.

That'll be Carlton.

Leo's father.

Miss Kingdom didn't see
eye-to-eye with the victim,

neither did English
teacher Luke Fawcett.

According to Penny, he was sacked

and now lives in a caravan
close to Troy Vale.

Where the victim went butterfly
collecting this morning.

Penny?

We should have a word with Mr.
Fawcett, but first

I want to find the spare
summer house key.

If you can cr*ck this code to Mr.
Sidana's office.

Seeing as you're the clever one.

Well.

May I?

Go ahead.

1-8-3-2.

Oh.

Two-two.

Window's been broken in.

And there's no sign of a key.

Luke, Grady needs you.

Mahesh has been k*lled.

Well why does that mean
that Grady needs me?

He's got you.

But, you're a member, I'm not.

Right, there is that.

I'm a bit busy.

And if you are planning
a barbecue this weekend

I would hold fire for awhile.

The whole of the region

will be covered in cloud for
the next couple of days.

Same go...

Anyone here?

Hello?

Ginny?

Carlton, where are you?

School.

It's Leo's first exam.

Well, you're meant to be here!

Nothing good ever came out of Circulus.

It went really good actually.

How did it go?

Did you answer every question?

- It was fine, yeah.
- What came up?

Science, maps and hurricanes.

Yes!

Come on, now, home.

Excuse me?

Do you won the Nobel Prize
for literature in 1907?

Birgitte?

No, I don't think it was me.

I thought maybe Rudyard Kipling.

Hey, Winter, Birgitte Poulsen.

From the Copenhagen
Police, I've heard a lot.

- Nice to meet you.
- I'm flattered.

But why are you here in Midsomer?

To join Circulus, of course.

- Thank you.
- What about Luke?

- I... Well,
- What?

I looked for him and
he wasn't at the caravan.

I did eventually find him in the pub.

- In the pub?
- Yes.

Why didn't you get him out of there?

I know about Circulus from my father.

I thought I might give it a go.

You should've let me know,
you could've stayed with us.

I rather like the sound of
Eddie's Bed and Breakfast

and I didn't want to impose,
you are a busy man.

Has someone else been poisoned?

Mahesh Sidana perhaps?

On the exam documentation he
was named as invigilator,

and yet Mr. Palmerson stood in for him.

Inspector Poulsen is a
very find detective.

Very fine, indeed.

John couldn't stop talking about you

when he came back from Copenhagen.

Sarah.

My wife.

My pleasure.

So this is a family affair, is it?

I didn't think it was, no.

Grady Palmerston rang, he needs someone

to invigilate a mark.

Apparently someone k*lled Mahesh Sidana.

I can't stop,

come for dinner tonight?

- You, too, Jamie. Eight o'clock.
- Great.

- Lovely.
- Lovely.

Super. See you later.

See ya.

Yeah... see you.

What's going on?

I have absolutely no idea.

- We have to speak with Luke Fawcett.
- Mhm.

I gather he's in the pub.

Three-two.

Okay, thank you.

Forensics have found a partial

fingerprint on the broken window.

Tech team have emailed through
Anika's phone records.

They seem to stack up.

Oh.

Mr. Fawcett, DCI Barnaby, DS Winter.

Where were you first thing this morning?

Um, um, the caravan and then here.

Is this about Mahesh?

Did you see him this morning.

Yes, first thing, about sevenish.

We didn't chat.

Fellow butterfly enthusiasts,

fellow teachers, I woulda thought
you had a lot in common.

I'm sure you know our history.

Otherwise you wouldn't be here.

Why did he sack you?

Because he was a sl*ve to
the national curriculum.

I believe in freedom of expression
and not limiting peoples

to pedantic rules and
out-modish principles.

You seem to get on okay here.

Yes, well... times change.

Can't be easy losing your job.

I've never been happier.

No, I should thank him.

Did you see anyone else this morning?

Only the woman following Mahesh.

- Who was?
- I've no idea.

I've never seen her before.

About 40... blondish hair...
long green coat.

Someone's snooping around.

And you're meant to be here!

I have to focus on Leo.

The boy, he needs air.

Not Circulus.

Noticeably our money.

Grady's being a pain.

Could I get an advance?

I may be old, but do I look stupid?

You'd be doing me a favor.

Giving you a job was doing you a favor.

Oh, Eddie!

Is it possible I can have
a cup of tea, please?

Course.

- Follow me.
- Yes.

How did you find the general knowledge?

Oh, so-so, and you?

It was tough.

I really need to shine tomorrow.

Although math has never
been my strong suit.

Well, and neither has lateral thinking.

I mean, how are you supposed
to prepare for that?

Practice.

Listen, you're in a room and
there are two ways out.

One is engulfed in flames, the
other one is full of lions

that haven't eaten for two months.

Which way do you go?

- Engulfed in flames.
- Yes.

Oh, that's not good, is it?

No.

Mind... Neither are hungry lions.

I know, is there a trap door?

Oh, I'm afraid not.

I give up.

You go towards the lions

because if they haven't
eaten for two months,

they're already dead.

Oh, that is good, that is very good.

And if you don't get in,
you might try a bribe.

From what I've heard, it
wouldn't be the first.

Yeah, I have heard that some people pay

for advanced knowledge of the questions.

Who did you hear this from?

Mostly people who didn't get in.

Oh.

Uh, how can I help, officers?

Actually, it's one of your
guests we want to see.

Miss Poulsen.

We need to ask some questions.

Am I suspect?

How exciting.

Is this about butterflies?

When I was out this morning

I saw Mahesh Sidana collecting them,

and just now I've seen
that Eddie here...

has a room full of books about them.

Perhaps you'd like to
have a word with Mister...

Rowbotham.

With a thhh.

Butterflies.

It's a hobby of mine.

Which one's your favorite?

- Me?
- Yeah.

I like the blue ones.

Like the Marsh Fritillary?

Absolutely.

Yeah, I love that one.

Golden brown on a black background

with a hint of yellow on the underside.

But um, nothing blue.

Not even when it's cold?

Not even when it's cold.

Look, I'm new to it, all right?

I wanted to join the local
lebi-what's-it group.

Oh, I was trying to swaddle by just...

How well did you know Mr. Sidana?

Well, not very.

Not really at all.

I just run my B and B and do a
bit of cabbing on the side.

Oh, our paths never crossed.

How did you know it was Mr.
Sidana you saw in the woods?

I'm a detective.

If I want to join an organization

I want to know everything about them.

I saw his photograph several times.

How was he k*lled?

I'm not at liberty to say.

Oh, come on, please.

Just that following a phone call from

a Mr. Palmerston Sidana's wife...

What?

You'll have to excuse me.

Anika Sidana told us

she was at an editorial
meeting in Newton Magna

when she received
a call from Grady Palmerston.

She went home to find her husband dead,

at which point she rang the police.

Correct.

Grady rang her at 10:03,

Mrs. Sidana rang the police at 10:09,

six minutes later.

Newton Magna, as you are about to see,

is at least 15 minutes away.

So she couldn't have been at work

when she received the call.

Where was she and why did she lie?

- Yeah.
- Oh, hello!

DCI Barnaby, DS Winter.

- Mrs. Palmerston?
- Yes?

I do the diary, home and
living, and pets sections.

How can I help?

Was there an editorial
meeting here this morning?

Oh no, we had it last week.

Was Mrs. Sidana in this morning?

Well, not first thing.

She got here about 20 minutes ago.

Detective Dooda and Sergeant Thingy.

At work today of all days?

Oh, I had to get out the house.

It's too many consoling phone calls.

Earlier you told us you were here

when Grady Palmerston rang.

But you weren't, were you?

Um, I, I, I had just been for a walk.

Why not tell us that earlier?

Mahesh and I had a row
and I didn't think

that it sounded good
under the circumstances.

What did you row about?

Work.

He hated me doing this job.

Sir.

A bit unseemly, isn't it?

Commissioning an obituary so soon?

I didn't.

It just arrived, it
doesn't say who from.

What it does say is exactly
how your husband was k*lled.

Hoist onto a wall, drilled
like one of his butterflies.

Who would know that?

Only us, Mrs. Sidana.

And the person who k*lled your husband.

Why send an uncomissioned obituary

flaunting the fact that
you know what happened?

To show off?

The tech are checking the IP address.

Okay.

Wife Anika lied about her movements

and said she rowed with her husband.

Then presumably didn't
send herself the obituary.

So.

Luke Fawcett has motive against
the boss that sacked him.

Agreed.

Eddie Rowbotham?

Said that he barely knew Mr. Sidana

but has recently bought a
load of stuff on butterflies.

Anyone else?

Penny Kingdom knows a
lot about butterflies

and doesn't like Circulus.

What about Grady Palmerston?

I did some digging, by the way.

Used to have publishing interests

in Germany, France and Denmark.

He was certainly keen to distance

the m*rder from Circulus but
I can't see a motive as yet.

Another suspect.

There was a serial
number on the drill bit.

Belongs to equipment
purchased by Virginia Welton

of Borrowdale Farm.

Mrs. Welton?

D.S Winter, Causton CID.

Hello?

The water of life.

Skal.

Cheers.

That's definitely not water.

Not for you, Paddy.

Time for my confession.

I'm a police officer.

Detective Sergeant Winter.

Can I please just reach
for my warrant card?

Hold it to the side, my
central vision's smashed.

Peripheral, okay?

Oh, why didn't you just say that?

Well, you didn't give me a chance.

Do you normally greet your
visitors with a shotgun?

I thought you were an intruder.

Someone keeps trespassing.

Is that firearm licensed?

Yes!

It was only a warning sh*t,
I was aiming at the bucket.

Do you want me to prove it?

No, no!

No.

17 years ago a student
called Anders Nisson

threw himself of Oresund
Bridge in an apparent su1c1de.

He was a friend of my father,
both Circulus members.

Apparent?

Anders contacted my father
the night before he d*ed.

He wanted to meet.

He said he had uncovered
a secret about Circulus

but the meeting never happened.

And your father thought he was k*lled?

Yes.

And he tried to look into
it but he was forced

to leave the group for
voicing his suspicions.

So why are you here now?

Two reasons.

I came across my father's notebooks

and an entry that said the
answer is in Little Crosby.

Did he say who was involved?

No, but I have my suspicions.

Yeah, skal.

Carlton's here to see you.

G and Ts?

Just leave us, Celeste.

I got your text.

I need time.

You don't have any.

Your tardiness rules Leo out
of contention for membership.

The rules explicitly state
all application fees

have to be cleared through
the Circulus account

before the exams begin.

Why are you doing this?

You know Leo would be an
asset to the organization.

Like Jane was.

Even if you did stop her from being

in charge of social events.

- She wasn't well.
- I know!

And I'm still paying for that.

I can get you the money.

How much do you want?

Are you trying to bribe me?

I'm trying to appeal
to your better nature.

Assuming you've got one.

I think we're done, don't you?

Why not tell me all this earlier?

'Cause it's not official
police business.

I've taken leave to pursue
the matter privately.

You know Grady Palmerston used to have

business interests in Denmark?

Yes, I know.

Does he know why you're here?

No.

I have a different surname to my father.

You said there were two
reasons why you came here.

What's the other one?

My father d*ed last month.

I'm sorry to hear that.

My mother d*ed when I was quite small,

so me and my father were very close.

He had been ill for some time...

but... grief is strange.

Comes at you from odd angles.

I thought I was fine about his death,

but then I read his notebooks.

And now I feel compelled to find out

what happened to Anders.

Where's Jamie?

I'll need to take your drill
tool for forensic analysis.

It might've been used in a crime.

Well, if it was, someone took it.

Perhaps that's who I've been hearing.

Does anyone else have access to it?

Carlton.

Carlton Scott.

Works for me.

When he turns up.

I'll need his details.

What was that?

Wait here.

And put that down!

Who's there?

Police.

Stop!

Oh, perfect.

Maybe I can help.

After tomorrow's exam I'll be
marking at Grady Palmerston's.

I can be your mole.

You will be nothing of the sort!

Palmerston is the suspect
in a m*rder investigation.

Yeah, possibly two.

John is right.

I couldn't possibly
impose on you in any way.

Birgitte, you can use
Causton's resources

to help with your investigation.

And, of course, your skills
might be useful in ours.

You're most kind.

Paddy!

Mommy!

I had problems getting a bottle.

Mags!

Okay, thanks.

The earth auger at Borrowdale Farm

is being confirmed as the m*rder w*apon.

Ginny Welton's prints are on it.

So either she's the culprit,

or the m*rder*r stole the equipment

and wiped it on return.

How far is her farm from
the Sidana's house?

Same side of the village.

The farmland's been in her
family for generations

and includes the meadow.

She employs a land
surveyor Carlton Scott.

His son's applying to Circulus.

And his wife passed away.

Oh, and guess what.

His fingerprints match the partial one

found at the break-in.

How come we've got his fingerprints?

He's got form six months ago.

Verbal as*ault at a school prize giving.

The target of the att*ck?

Mahesh Sidana.

Are you all right, sir?

Fine.

I'll speak to him, you
speak to Penny Kingdom.

The motorbike registration you clocked,

it's hers.

Mr. Scott.

D.C.I. Barnaby.

Sorry, we have to go,
we've gotta be somewhere.

Indeed you do.

With me.

To explain your verbal
as*ault on Mahesh Sidana.

Jane d*ed after a short illness.

I didn't cope very well

and I thought the school
could've done more.

I objected to their
everyone-deserves-a-prize principle.

I happen to think the
best people deserve them.

Meaning Leo.

He should've won every prize.

But like I say, I wasn't coping.

Why does Leo's progress
matter so much to you?

Jane was a clever one,
a brilliant lawyer,

who gave up her career
to start a family.

Leo was pretty much everything to her.

Pretty much?

She missed the stimulus
of her former life

so she joined Circulus
for the social side.

She was keen for Leo to become a member.

Look, can we cut to the chase?

I gotta get Leo to this exam.

Of course.

How did you get on with Mr.
Sidana after your altercation?

We put the incident
behind us, we moved on.

So why did you break into his office?

Cut to the chase enough for you?

Mahesh was the treasurer.

I've had cashflow issues.

I realized the entrance
fee was gonna bounce.

I figured it might become a problem.

So you were robbing his study?

I thought Mahesh kept records there.

I wanted to find proof they took bribes.

I wanted something over
them in case it got ugly.

And did you find anything?

No.

Did you take a key?

No.

Miss Kingdom.

In here.

They like you.

Whereas you try to run me over.

You may begin.

Congratulations, your
father would've been proud.

The Danish woman, do you know her?

No.

That's odd.

Seeing as like your husband...

she's a senior police officer.

I know nothing about
drills or meat hooks,

I was looking for pesticides.

In the dead of night?

Well, I went earlier but the
old witch nearly caught me.

She's behind the disappearance

of the Small Coppers, I'm sure of it.

Don't be fooled by the
blind old bat act,

she's as tough as old boots.

That I can believe.

She opposed the butterfly farm,

didn't want it on her land.

You still haven't explained
why you tried to run me down.

If I'd of wanted to hit you I would've.

Is that meant to be reassuring?

Excuse me.

D.S. Winter.

Yeah, onto it.

Sorry, I've gotta go.

So, something's come up.

10 seconds.

If you read this
question before starting

the rest of the exam
just write your name

at the top of the paper and leave.

You will be given 100%.

Pens down.

Congratulations, the ordeal is over.

Let the party begin.

Grady knows who Birgitte is.

What is it this time, Inspector?

We wanna talk to you about
Mahesh Sidana's obituary.

We traced the IP address, your computer.

Well, I didn't write it.

It's too well written for Celeste.

So, I'm afraid I can't help you.

It describes the exact manner of Mr.
Sidana's death,

information privy only to the police,

Mrs. Sidana, and...

The m*rder*r, yes I get that.

Quite a conundrum, isn't it?

Nothing like a mystery to exercise

the brain cells, is there?

We need you to explain it.

I don't need to explain
anything, young man,

that's your job.

I'm disappointed you haven't
made an arrest yet.

I have my suspicions who
the k*ller might be.

- Do you now?
- Yes.

I'll let you puzzle it out.

I think he's the m*rder*r.

But as he pointed out,
we have to prove that.

And I intend to.

Think of it as Danish feng shui.

Everything in a place and
a place for everything.

Everything was in its place.

Here in England we use the crime board

as a place for evidential facts not...

idle speculation.

We do the same in Denmark.

But you've moved Anika
Sidana and Luke Fawcett

side-by-side and written
affair between them.

Based on what?

Your evidence.

Her phone records.

If you look over the last few weeks

there's the same number
ringing several times

after one o'clock in the morning.

Fleur told me this was, what was it?

A booty call, love.

The number belongs to Luke Fawcett.

The man her husband sacked.

An affair gives the motive.

Yes, well, very good,
I'll pay her a visit.

- Anything else?
- Yes,

the coffee here is terrible.

What about you?

One of two things.

Not least Grady Palmerston
knows who you are.

I know, I have to be careful.

Right, I'm off.

Help yourself to tea,
coffee, gin and tonic.

Great, thanks.

I'm doing the music at the party.

Oh.

Join us, you'll need a
drink after that lot.

Well, thank you, but I really
should be getting home.

Well, let yourself whenever.

Have a good night.

Thanks.

Getting rid already?

They've always creeped me out.

They're very popular around here.

Your husband, Penny
Kingdom, Luke Fawcett.

How well do you know Mr. Fawcett?

Ah. Speak on the phone much?

Bear in mind you've
already lied to me once.

Are the two of you involved?

Is that where you really
were yesterday morning?

With him?

Nobody likes admitting to infidelity.

It doesn't sound good, does it?

Where were you when your
husband was k*lled?

Did you come straight home
after you left Mr. Fawcett?

No, no, I went for a walk.

Needed to clear my head.

When did your affair start?

After Luke got the sack.

Do you think he could've
k*lled your husband

out of revenge?

Our affair is his revenge.

And you're okay with that?

I'm not proud of it, but...

Mahesh wasn't a particular

imaginative man and Luke is...

the opposite.

And he was sacked over his
approach to education?

That's what they said, but who knows.

Mahesh, Luke, Grady,
they go back a long way.

I'm a Circulus widow
in more ways than one.

- Come in.
- Hi.

Okay.

So what are we looking for?

Anything that links
him to Anders Nisson.

Okay.

It's Palmerston.

Oh.

Okay.

Birgitte, you've gotta go.

Now!

You're still here?

Uh, yes, yes, I've familiarized myself

with the answers and made a start.

How's it going?

Good, yes, but one of
your answers is wrong.

X-rays and photons
that's the right answer.

What did you think it was?

Good work, Winter.

Much more like it.

Where's Inspector Poulsen?

I went to get coffee.

What happened?

Oh, it's terrible, isn't it?

Winter, really.

Actually, I think I can prove

that Grady Palmerston
wrote the obituary.

Phrases from his editorials,
phrases from the obituary.

They're the same.

Never quite had the wherewithal in both.

But there is a sense in which in both.

And who quotes Plutarch twice?

Circumstantial, Winter.

But surely enough to confront him about.

Hey, there, pint of Grace Ale, please.

Grady Palmerston!

Big house for a small publisher.

Mr. Palmerston?

Mr. Palmerston?

We got a partial on the window balcony.

Ethyl acetate again.

Cause of death: cardiac
arrest following repeated

and incremental electric shocks.

Overloads the systems, stops the heart.

And set up, the m*rder*r
didn't even have to be here.

m*rder in absentia.

Clever, or reckless.

All the questions low brow.

Popular culture, bands, television.

Questions Grady Palmerston
wouldn't know the answers to.

A victim of his lofty intelligence

in the same way that Mahesh Sidana

was made a victim of his obsession.

Eddie was right about bribes.

Palmerston kept a list of donations.

But years ago there seems
to be much larger amounts.

40,000 pounds.

75,000 euros, dozens of them.

Explains the house, but
what were the payments for?

Can you go over everything
on the computer?

Of course.

Any link to Anders Nisson's death yet?

No.

Perhaps we'll never know.

Celeste Palmerston's here.

Champagne?

Uh, no, thank you.

Be a darling, I don't
want to ruin my nails.

Can you talk me through your
movements this evening?

Sure. I left your wife here

and I went to the party.

My wife was here on her own?

Yes, why?

Do you think she did it?

No, I don't.

Well, Grady was going
to come along later,

make a speech.

He came home to write it.

Your husband's computer was on.

Seems he was looking over
financial transactions

relating to Circulus.

- Do you know about them?
- Haven't a clue.

Did you husband know
that Eddie Rowbotham

thought bribes had been taken?

Of course, he just told Eddie to shut up

and concentrate on his tutorials.

What tutorials?

With Mahesh.

Mr. Rowbotham said that he rarely

crossed paths with Mr. Sidana.

Rubbish, he'd been cramming
with him for months.

Anyone had odd or unusual dealings

with your husband recently?

Carlton Scott came by last night,

I don't know what that was about.

What about today?

Did your husband seem troubled at all?

No.

Oh, he went to school
early to meet someone.

Who?

He didn't' say.

I'm gonna have a swim.

Hold this!

Oh!

Oh, Geronimo!

People respond to grief in
different ways, Winter.

Celebration not normally
being one of them.

Are we going to announce
Grady Palmerston's death?

No, I think a stealth approach
might be more productive.

Crosby Courier.

I think your Miss Kingdom
wasn't a fan of Circulus.

She's not... mine or a fan.

How was maths and lateral thinking?

Well, it's hard to tell, really.

I got the riddle one right, though,

you know the one about
the fork in the road.

- Did you wanna hear it?
- No.

No, I can't stand riddles.

Apart from why you told me

that you didn't know Mr. Sidana

when you had tutorials with him.

Because it stopped.

So?

Mahesh lost patience with me

and he refused to tutor me anymore.

Said I'd never pass in
a month of Sundays.

And how did that make you feel?

Ashamed.

What about angry?

No, just ashamed.

Leaving so soon?

Not really my thing.

You mentioned earlier
doing the break-in

so you could have something over
Grady if things turned ugly.

I told you I didn't find anything.

Did things turn ugly anyway?

You went to see Grady
Palmerston last night.

What about?

An administrative confusion.

It's resolved now, we moved on.

Like you said you did
with Mahesh Sidana?

Exactly.

Didn't expect to see
you in the enemy camp.

This is my local.

I'm not gonna sit at home
because of that lot.

Though I doubt I'll
stay for the duration.

Unless you are.

Yeah, I might do.

Catch you later then?

On your own tonight?

Looks that way.

Tell me, Grady, chairman,
Mahesh, treasurer.

What do you do?

Crosswords.

So why is Penny here?

It's her local.

Crawling with people she disapproves of?

Strange, don't you think.

Not as strange as you doing a crossword

when you're working.

Baby ran in circles around

clueless inspectors, seven letters.

Baby ran, clueless inspector.

Barnaby?

Doesn't count, I've already got it.

It's three all.

Grady said he'd leave
us to puzzle it out.

He's true to his word.

Something's been bothering me
about the obituary, though.

We thought Grady Palmerston wrote it

and we thought he was the
m*rder*r as a result, but...

And he's clearly not.

So the obituary's meant to frame him.

Which it did.

So whoever wrote it studied
his language like you

in order to point the
finger in his direction

knowing that we would
trace the IP address.

So why frame someone and then k*ll them?

Exactly.

And the answer is?

No idea.

Oh.

I think I'll stick around for a bit.

Be careful, Winter.

- Draft.
- No, you.

Come on, once.

That's twice!

I should probably go.

- I'll say goodbye.
- I won that

so I should slap you.

I'll close my eyes while you go.

I enjoyed tonight.

More than I have for awhile.

Me, too.

I don't.

Ah, she's gorgeous, isn't she?

That's the rest of us
done for, isn't it?

That, I shouldn't.

Because of work and...

Of course.

I'm sorry.

- Friends?
- Sure.

Friends.

Goodnight.

Try this.

m*rder*r, a prodigal Samaritan
on the road to Emmaus.

How many letters?

I'm better if I get the letters.

Four.

Biblical.

Cain.

Abel.

Esau.

Hi, hello, thank you.

I think I found a link to Denmark.

But also something else.

Look.

I was going through all the exam papers,

dozens of them, with this.

The right answer.

And then this.

You're not gonna get any
marks for that one.

Exactly.

I've checked the internet,
an engineer who worked

for one Europe's leading
car manufactures.

So this isn't the answer
to that question.

No, it's the chemical
composition of an engine oil.

I think they use the exams
to trade on secrets.

Industrial espionage.

Question is, who knew about it?

Luke.

The prodigal son, the good Samaritan

and Jesus on the road to Emmaus

only appeared in one gospel: Luke.

Did you finish the crossword?

It's Grady's idea of a joke presumably.

Is it?

We checked the constitution.

In the even of the death of chairman

the running Circulus passes to the next

surviving founding member.

Luke did business Circulus

of which there was originally four.

Recently three.

- Mahesh Sidana.
- Dead.

- Grady Palmerston.
- Dead.

And you.

May we come in?
We'd like to search your caravan.

- What for?
- Their summer house key

or anything that might link
you to a m*rder w*apon

taken from Borrowdale Farm.

Did you say Grady's dead?

Or electrical equipment
used to, yes, we did,

k*ll Grady Palmerston.

No, you can't come in.

I think we can.

What's in there?

Junk.

It's just full of junk.

No, you've no right.

Any differences I had with Grady were

ideological and not psychopathic.

I wouldn't k*ll over it.

Grady Palmerston thought you would.

He knew of your affair with Anika Sidana

and thought you wanted
revenge for your sacking.

Well, the great Grady thought wrong.

Mr. Fawcett, in the past 36 hours

your lover's husband
and the only obstacle

to you taking over Circulus
have both been k*lled.

Maybe that just means I'm next.

Why would you be next?

Wouldn't have anything to do with

trading secrets
internationally, would it?

- That was nothing to do with me.
- You knew about it.

And disapproved.

Was Mahesh Sidana involved?

He banked the money.

Did you fall out with him as well?

We had our issues.

Can you account for your
movements yesterday evening?

I was here until I went to the pub.

Much like the day before.

I'm a creature of habit.

Like seeing Mrs. Sidana.

She didn't go straight to her house

after your latest tryst.

Perhaps you did.

You followed Mahesh
into his summer house.

You could've done the same
with Grady Palmerston.

Trust me, I didn't.

You're a hard man to trust.

Penny Kingdom thinks that you share

her concern for the plight
of the Small Coppers,

when, in fact, you're
hoarding them here.

What's she gonna say when we tell her?

She'll be gutted.

It was her idea to hide them
here in the first place.

Any Small Coppers in there?

You know there aren't.

Because they're all in
Luke Fawcett's caravan

where you lured, trapped
and captured them.

To protect them.

By imprisoning them?

It's no different to Mehesh Sidana.

A world of difference.

We're trying to protect
their longterm future.

Ginny Welton has plans
to use the meadowlands

for crops, that's why she's
hired Carlton to oversee it.

It's her land, she can
do what she wants.

If she does, she'll wipe out
Small Coppers and others.

You care an awful lot about
butterflies, don't you?

Nature's proof of reincarnation?

Absolutely.

Symbolic of rebirth that life
goes on, it's important.

You weren't looking for
pesticides on her farm, were you?

You were planting them.

Your posters spread the word
that a species has disappeared

and then you were gonna
mysteriously locate the pesticides

on Mrs. Welton's farm
that mighta k*lled them.

Creating a public outcry.

Quite the campaigner, aren't you?

You said you were putting up posters

the morning Mahesh Sidana was k*lled.

That's right.

We've driven round the
village, we found five.

Not very many, is it?

Grady ripped the others down.

Tit-for-tat for me
leafleting about Circulus.

Grady Palmerston is dead.

And...

He recently paid you a visit.

When and what did he want?

Yesterday.

It was private.

At some point yesterday Grady Palmerston

went from being someone to
frame to someone to k*ll.

Something changed,
perhaps in your meeting.

I don't know what you're talking about.

He wasn't happy about me leafleting,

he was flexing his muscles, that's all.

You teach Set One Biology

and the brilliant Leo Scott is down

in Set Two with a different teacher.

Why?

Biology's not his forte.

Now what?

According to the original
Circulus membership list,

the four founding members were M.
Sidana,

G. Palmerston, L. Fawcett

and... the V. Astergaard.

V for Virginia, married
name, Astergaard.

Grady's boss in Denmark.

She divorced, returned to the U.K.

And reverted to her family name, Welton.

So she could be your link, not Grady.

With your permission I
would like to visit her.

Of course.

And take Winter, I gather
she can get trigger-happy.

Where are you going?

Penny Kingdom said Grady Palmerston

was trying to flex his muscles.

She's not a member of
Circulus so he couldn't

get at her that way, but
he did own a newspaper.

Something come up?

I can go on my own if you want.

Yeah, maybe that'd be good.

I'll ring Mrs. Welton, let
her know that you're coming.

Thank you.

Yes, it's absolutely fine.

I'll be waiting.

Grady Palmerston penned
crosswords and editorials,

did he write anything else?

Well he owned the newspaper,

he could write what he wanted.

Did he have anything over Penny Kingdom?

Something to do with a student.

Leo Scott by any chance?

He's not in her class
and his father told me

the school could've done more.

Oh, the school did
loads after Jane d*ed.

The school asked Penny
to be there for Leo.

She spent a lot of time with him.

Organized a grief
counselor, all of that.

So what went wrong?

It was more what went right.

Carlton was grieving, he
was lonely and vulnerable.

Penny felt for him, he
was attracted to her.

They started a relationship.

Until Carlton's grief turned to guilt

and he ended it.

Was this relationship public knowledge?

Mahesh was the only one that knew.

So, Penny becomes a thorn
in Circulus's side.

She organized a petition

putting pressure on Mahesh

not to let the school be used

for Circulus exams.

- It didn't work?
- Nearly did.

Close enough for Grady
to want vengeance.

He twisted Mahesh's arm

to let her go by the end of the term.

And your husband told Grady

about Penny's affair
with Carlton Scott.

How did you find out?

Grady could be vindictive.

Treacherous teacher abused position

to seduce grieving father.

Was this going to run?

Possibly next week.

Grady wanted to speak to her first.

Old news, though, isn't it?

Not around here.

It's gossip.

It's gold dust.

Professionally that could
ruin her reputation.

You have your father's eyes.

And his notebooks.

Come inside.

I have something for you.

You don't seem surprised to see me.

Grady followed your
father's obsession with a...

with an interest that
bordered on paranoia.

We all knew he wasn't gonna let it go.

You mean the four original
founding members.

What happened to Anders Nisson?

Your father was right.

In the light of Grady's death

there's no need to hide the truth.

Anders uncovered that Grady
was using Circulus as a front

for introducing contacts and exchanging

information all over Europe.

Did Grady Palmerston k*ll Anders?

Grady arranged for them to meet.

They rowed...

and he pushed him off the bridge.

He admitted it and we all
agreed to cover it up.

- Why?
- Oh, we were all implicated,

we all know about the espionage.

He said he'd take us all down with him.

When your father suspected...

I gave up Circulus altogether.

Mahesh took a backseat and Luke

disappeared into his own world.

Other things ended as well.

Your father talked about you such a lot.

I want you to have this.

He always hoped the two
halves might rejoin.

Perhaps now.

I have to take you to
the police station.

And you'll have to make a
statement about your involvement.

Of course.

That's what your father would've wanted.

Yes.

Miss Kingdom?

I know why Grady came
to see you yesterday,

I've seen his article.

Was he going to publish it or
just use it to silence you?

Publish it if I contested the sacking

that was coming my way.

The old charmer.

But now your job is safe

and the article won't be published.

I'm a Biology teacher, I
believe in life, not death.

Two people you were in conflict
with have been k*lled.

So?

- I was going to leave anyway.
- Really?

I've already been applying for jobs.

Grady was always banging on
about how I don't fit in here.

He was right, maybe I'm the problem.

Trying to change people that
don't want to be changed.

Carlton Scott?

Does it matter?

It might matter very much.

How strong were your
feelings for each other?

My feelings were very strong.

And his?

According to Leo they were.

He said it was nice to do stuff

and see his father smile again.

Reborn, even.

Grief comes at people from all angles.

Did you tell Carlton
about Grady's article?

I left him a message, I
had to warn him in case.

What are you looking for?

My phone.

Must've lost it last night.

Penny?

Penny!

Oh, come on, come on.

Who else was in the pub late on?

Leo, Luke, Eddie, Jamie.

Did anything happen?

Anything that could've upset anyone?

I kissed Jamie.

And who witnessed that?

Anyone who happened to be looking.

Who's there?

I think someone has targeted,

is targeting, people connected to you.

Hello?

Why?

I think because they care for you

and your relationship with someone else.

And they want to be a family again.

Where is he?

I dunno.

- Out.
- Where would he go?

A favorite place, think!

I know.

You think you're clever, don't you?

Stealing Penny from my dad?

I haven't!

Try this one.

- This what?
- Riddle!

- I hate riddles.
- Tough.

If you get right within
five minutes, you live.

If not, lover boy gets cupid's arrow.

You come to a fork in the road.

Two people stand there,

one is an angel that will
always tell the truth,

one is a devil that will always lie.

One road leads to life, and
one road leads to death.

You have to ask one of them a question

that would determine the way to life.

Only you don't know which
one you're asking.

The angel or the devil?

What is the only question you can ask

to determine the correct answer?

Five minutes.

Meet me at Frampton Woods.

There's a clearing in the middle.

I don't understand, what's going on?

You ask the angel, no,
no, wait, wait, wait,

hang on a sec.

You ask the devil...

I told you, you don't know
which one you're asking.

I think he went to the
school and stole a key.

What, you're saying Leo has
something to do with this?

Did it not occur to
you what your actions

were doing to him?

What are you talking about?

Your son suffered the trauma
of losing his mother,

but in the fallout from that

there was a support
system there for him.

Someone who eased not
just his pain, but yours.

You ask either one which way,

no, no, no, no, no, no wait.

Two minutes.

Come on, every second counts.

Why are you doing this?

I was Leo's friend, that's all.

You were more than that,
you were part of a family.

And then you two were taken away

and replaced by Circulus
and intelligence.

I thought that's what his
mother would've wanted.

She might've wanted an outlet
for her son's emotions,

too, don't you think?

But you blocked that, you sent Leo down

a different route entirely.

Some butterfly effect.

What happens to a caterpillar
that can't be reborn?

It eats itself and dies.

- Leo!
- No, no, no, stay there!

You stay!

This fires the crossbow!

Let him down, Leo.

Leo, please. Please don't do this.

It's a bit late.

- It's not!
- It is!

What took you so long, Dad?

Why couldn't you see that
Penny was the answer?

Why does everyone I
love always leave me?

- I did what I thought was best.
- I did what I was told.

I stuck to the rules, I
did what you wanted.

I was biding my time hoping
you'd see Penny again.

And protecting that possibility.

I don't understand.

Mahesh, Grady?

I heard Mahesh warning
you about Circulus.

Threatening you.

Breaking into his office was easy.

I saw the email to Grady.

Plotting he was gonna sack,
you would've had to leave.

So you taught him a lesson?

I turned him into one of
his dead butterflies.

And then you tried to pin it on Grady,

but what changed?

I saw the article on Grady's computer.

About them.

It was so unfair.

You wouldn't of stood a chance.

I just want you to be happy again, Dad.

And no one, no one is gonna
take that away from me.

Leo, please, you gotta stop this.

No, I can't!

Rules are rules, remember?

Rules are rules!

He has to answer the
question, he has 30 seconds.

What question?

You see, you come to a fork in the road,

two people are standing there.

One is an angel that will
always tell the truth,

and one is a devil that will always lie.

One road leads to life,
one road leads to death.

You have to ask one of them
a question to determine

the routes to life.

You don't know which one
you're asking, though.

Well, what is the only question you can

to ascertain the correct answer?

I really don't mind if
you take this one, sir.

Not a problem.

Leo, don't do this.

10!

No, please don't!

If I was to ask the other
one which way to go,

what would they say?

And then you do the opposite.

- Yes?
- Yes?

That's that.

It has to be him that to answer details.

Details! Five!

Okay, if I was to ask the other one...

which way to go what would they say.

And then you do the opposite!

You're too late.

No, Jamie!

Don't take me!

- No!
- It's okay.

It's okay.

It's all right.

I stood by and did nothing
when one life was lost.

I wasn't gonna let that happen again.

I'm so proud, I did it for you, I was.

I did it for you, I did.

Oh, hello.

Oh.

Come on, better get a wiggle on it

if you're gonna b*at the traffic.

Charge this one to us, Eddie.

What, plus tip?

Only 10%.

Oh, come on, John, 15!

Eddie's a bonafide Circulus
member now, you passed.

Hey.

Oh, sorry!

So, it is.

Well done, Eddie.

Thank you for everything.

I learned more about my
family than I ever dreamt.

Thank you.

Let me know how everyone gets on.

Thank you for letting
me stay last night.

You're welcome.

And you must come to Copenhagen soon

so you can bring some more aperitifs.

I'll start lining my
stomach immediately.

Bye.

I wonder if they've got
pop quizzes in Denmark.

Just saying.

Question one, what happens
next time you go AWOL?

Well, there's no answer
to that question, sir,

because it won't happen again.

Correct.

10 points.
