Elementary (2012–…): Season 1, Episode 17 - Possibility Two - full transcript

Both victims work for ZBZ Security.
Company has a contract

with the Turtle Bay Historical Society
right next door.

Now, nothing's missing
from the museum.

We're canvassing the area for the gun,
shooter, any possible witnesses.

So thoughts?

Holmes, thoughts?

Sorry, sorry.
I was waiting for Ms. Watson.

I'm training her to analyze
every environment

with the keen eye
of the true detective.

Watson, thoughts?

Um...

Uh...

Looks like both men have been shot
in the chest one time.

Judging from the scuff marks
on the concrete,

looks like they chased
the suspect up here,

who then fired twice and then ran.

It's tough to say where he went.

The reason it's difficult to say
where he ran

is that no one ran anywhere at all.

Here we have
two deceased gentlemen,

both of them wearing
the uniform of ZBZ,

or so it would appear.

This man's patches
were recently sewn on.

His clothes are store-bought,
not made by a uniform company.

- So he was posing as a guard.
- Nothing is missing from the museum,

so we'll assume that he was looking
for access to the parking lot.

Easy to rifle through the cars
if you look like

you work for the security firm.
What was in his pockets?

- Pockets? Pockets.
MAN: Here you go.

Yeah, see, you thought he was a victim,
so you were looking for identification.

But here we have one, two, three,
four car registration cards.

Each one has the owner's
address on it.

See the game?

Pick an expensive car,
then you call an associate

who burgles the home of its owner
while they're out.

This man is a real security guard.

He saw this fellow lurking around,
followed him.

Bad man shoots good man.
Good man, while still alive,

wrests control of gun from bad man,
fires one shot.

Here we are.

- One more thing.
- His cell phone.

You're gonna check the last number
he dialed. That's his partner.

He's probably robbing
a place right now.

Would you like to talk to the burglar?

According to this,
his name is Loco Maurice.

You mustn't allow your failure
to discourage you.

[WATSON SIGHS]

Didn't fail. Not discouraged.

You didn't solve the case,

but you did notice the incongruity
of the scuff marks.

The next step is learning to extrapolate
your way to the truth.

Detection is not just a skill, Watson.
It's a point of view.

You must train yourself to be alert
to the bizarre, the unusual,

that which has no place
in any given picture.

Like that stretch limo
with the driver staring straight at us?

CRABTREE:
Sherlock Holmes?

My name's Crabtree. We got your
name from a Mr. Musgrave in London.

Local police told us
we'd find you here.

You say "we." All I see is a you.

I'm a driver and attach?
for Mr. Gerald Lydon

of Lydon Industries.
You know the company?

You make everything
from Scotch Tape

to diamond-tipped drill bits.

We have all the tape
and drill bits that we need.

- Thank you very much.
- Mr. Lydon has a proposal for you.

I sit before you a lucid man.

Vital, I might say.

I hold 18 patents and I can do
11 pull-ups at age 58.

And I own exactly 16 forks.

I'm not entirely sure
what we're supposed to be comparing.

Well, the point, Mr. Holmes,
is that in my good moments,

I'm every bit the man I was.

But there are fewer and fewer of those
because I have dementia.

And it's getting worse, which is why
Ms. Tompkins is following me around.

- You have my condolences.
- I don't want your condolences.

I want your help.

Have you ever heard of hereditary
cerebral amyloid angiopathy?

Hereditary CAA,
it's a genetic disorder.

Less than 20,000 cases recorded.

Dementia is
one of the early symptoms.

And death is the final symptom.

And when it comes to me,
it will complete my murder,

because somebody did this to me
and I need you to find out who.

So it's a hereditary disorder.
You have to be born with it.

LYDON: And there's no history of it
in my family.

They can do a lot of things
in labs now, you know.

And I've consulted
with some of the top geneticists

and they tell me that it's possible
that somebody gave me this disease

because they want me out of power!

With all due respect,
maybe these geneticists are right.

"Possible" does not mean likely.
It just means it's not impossible.

That's what my family says,
what the police say,

that I'm paranoid, that I'm delusional.

I hate to say this,
but those are also symptoms of CAA.

Look, they tell me that
you're the best.

Mr. Holmes, what will it cost
to buy you over to my side?

I only take cases when I believe
I'm acting in good faith.

Now, since I think that
naturally occurring dementia

is by far and away the most likely
explanation for your plight,

I would not be doing that.

Would you pull over,
please, Crabtree?

I really am truly sorry,
and I wish you the best of luck.

I read the last stack of books,
no questions asked.

But, uh, Jeremy Bentham
is a utilitarian philosopher.

That has nothing to do
with being a detective.

Bentham is the father
of modern criminology.

He said that crime
is the result of free will.

[DOORBELL BUZZES]

Uh, you're gonna put the acid away
before we answer the door, right?

Delivery for you, Mr. Holmes.

Thank you, Crabtree,
but I'm afraid I c...

Oh, my God.

- Is that...?
- A bee in a box? Yes, it is.

Fairly unimpressive
as far as bribes go.

Not if you're an apiculturist.

That's an Osmia avosetta.

Solitary bee famed for building
exquisite nests from flower petals.

It's on the verge of extinction.

Crabtree, this is exquisite.

I cannot accept it. Please,
tell Mr. Lydon not to contact me again.

I told him
you are a man of convictions.

Perhaps now he'll believe me.

This is ridiculous.
Single stick is your hobby.

[PHONE RINGS]

It's not gonna help me solve crimes.

Aim for the pate.

Good morning, captain.

GREGSON: Are you in bed
with a guy named Gerald Lydon?

He tried to hire me.

HOLMES: I declined.
- Well, that's not what he thinks.

You should get down here.
He's asking for you.

HOLMES: Why?
- I don't know, but we just arrested him.

He shot his driver,
guy named Crabtree.

He's being charged with murder.

GREGSON:
Lydon says he can't remember.

His nurse witnessed
the whole thing, though.

- There was some kind of episode.
- I've been patient. Excuse me.

- I want to see my father!
BELL: No, that's not gonna happen.

Okay? Your dad killed somebody.
This is a crime scene.

- You guys gotta step back.
- My father is sick.

- His attorney's on the way...
- Lydon's sons.

They're hands-on.
Anyway, he's asking for you.

Says you're the only one he'll see.

LYDON:
Crabtree worked for me for 23 years.

I know his partner.
I helped them adopt their daughter.

I don't know how I could think
that he would hurt me.

Uh, I'm having a hard time holding on
to what's real and what isn't.

This conviction that
someone did this to me,

I don't know where it comes from.

And maybe it is a delusion,

but everything in my life
feels so slippery, except for that.

That feels solid.

Help me!

[BEE BUZZING]

Hey, why do you have the box
with the bee in it?

We took Gerald Lydon's case.

- We did?
- Well, frankly I couldn't say no to him.

It would have felt like denying
a dying man his last wish.

We are taking this home,

and then we are going to the genetics
lab which confirmed his diagnosis.

At Watt Helix, we always say
our work isn't just about genetics.

It's about healthier food.
It's about a longer life.

- It's about you.
- Utter pabulum.

You'd think corporate science would
maintain some vestige of dignity.

His portrait was painted by
Kirian Boyd. That's impressive.

This place is a tower of ego.

KEATING:
So you're Sherlock Holmes?

- Hi. And Joan Watson, right?
- Yes, hi.

I'm Raph Keating, I'm president here.
This is Natasha Kademan.

She heads up
the medical research team.

Tash, meet Holmes and Watson.

- Hi.
- Natasha Kademan. I know that name.

You wrote your dissertation
on the warrior gene, did you not?

Ms. Kademan conducted a study
which many say isolated

the gene responsible
for sociopathic behavior.

Sterling work.

And why are you
plowing these fields?

My funding dried up.

The receptionist said you have
a question about Gerald Lydon.

Lydon thinks
someone gave him CAA?

Did you know about this?

KADEMAN: Sure. He used to
talk about it when he came in.

- It sounded delusional.
- And it may well be.

But Mr. Lydon
insists that geneticists,

whose names
escape him at the moment,

assure him
that it is technically possible.

You diagnosed his condition.

Your lab has researched
the disease extensively. Is it?

I guess if you had unlimited money,
a great lab, you probably could do it.

CAA comes from a mutation
of the APP gene.

There are may be seven people
out there that might be able to crack it.

Could I have their names
and addresses, please?

KADEMAN: Seriously?
- Mm-hm.

[HOLMES SPEAKING
IN NORWEGIAN]

Hey, what's this?

You're a detective now, you tell me.

Uh, it looks like you left
your dry cleaning ticket for me.

Yes, the reason being,
as well as being colleagues,

we are now embarking on
a quite unusual domestic partnership,

so we should aggregate our errands,
not duplicate them.

So I get the dry cleaning
and you get what?

I shall clean our refrigerator
once monthly. Agreeable?

You should pick that up early.
We're leaving for Norway tomorrow.

What?

I've been delving into
our magnificent seven geneticists

and I have discovered a connection
which merits further exploration.

This is Dr. Ingvald Moller.

He runs a lab in Oslo
which specializes in the study

of rare genetic disorders.

- He looks very Scandinavian.
- He does.

Now, his lab is affiliated
with the national university,

which means it's publically funded,

and yet Dr. Moller
recently put a down payment

on a home on the Geirangerfjord,

which was once owned
by the Norwegian royal family.

Lovely place.

Well outside what
a public servant could afford.

And interestingly, his loan papers
were cosigned by one Carter Lydon.

Okay, so you think that Carter
paid this guy

to figure out
how to give his father CAA.

Interesting.

But why do we have to go to Norway?
Carter Lydon lives right here.

I would rather question a scientist
than a businessman.

And Norway has fjords and glaciers,

and women reared on a diet
of wild-caught salmon.

Oh, that explains it.

[PHONE BEEPS]

Looks like a molecule.

[PHONE BEEPS]

"The thing itself."
That's a weird way to put it.

The warrior gene.

The warrior gene.
Where's the dissertation?

This is Natasha Kademan's
monograph.

I seem to remember something
in the conclusion.

"When it comes to understanding
sociopathic behavior,

understanding the warrior gene
is paramount.

- It is the thing itself."
- So Natasha sent this.

She knows what's going on.

Now she's panicking. Now she's trying
to figure out her next move.

And if she's as smart
as she seems to be,

now she's realizing
we are her best option.

[PHONE BEEPS]

[DOOR CLOSES]

Ms. Kademan?

Hello?

We found electrician's tape covering
the lock on one of the back doors.

It looks like someone slipped in
to commit a burglary,

found Ms. Kademan working late.

What were they planning to burgle,
blood samples? No, I think not.

Ms. Kademan's murder was connected
to the Gerald Lydon case.

The Gerald Lydon case is closed.

I'm not talking about the murder
of his chauffeur.

I am talking about the investigation
into who gave the man a substance

which induced his CAA.

Our most promising suspect
at the moment is Lydon's son, Carter.

CAA is inherited.
You can't just give it to somebody.

Ms. Kademan thought
it was possible.

In fact, she thought
that's exactly what happened.

You believe her?

She made someone nervous enough
to stab her half a dozen times,

I'm inclined to explore further.

I can also tell you
this was no robbery.

That portrait

was done by Kirian Boyd.

It is by far
the most valuable object in here.

Oh, well, it was until it was stained
with several drops of the killer's blood.

BELL:
The victim's blood is all over the place.

What makes you think
that came from the killer?

Excellent question. Watson.

Uh... Um...

Well, the spatters on the floor

indicate that she was facing away from
the portrait when she was stabbed.

Um, all of her wounds
are on her anterior side,

so it's tough to see how her blood
ended up on the portrait.

Um, now, if she tried to
fight back, then...

Then it's easy to see
how a blow to the killer's face

might result in those stains.

Kudos, Watson. Adequately done.

Oh, my God. Tash.

- Who's that?
- Victim's fianc?.

Came down for the ID.

I knew that she was working with a
dementia patient named Gerald Lydon,

but Tash never told me that
she thought somebody dosed him.

I'm a geneticist too, so I'm pretty sure
she would've said something.

Honestly, I thought you were
gonna ask me about that guy Benny.

BELL:
Benny?

Cordaro? Cordero?

He was in prison
for stabbing someone

when Tash was doing her
warrior gene research.

He claimed that she used his blood
without permission.

He came down here
like a month ago to scream at her.

BELL:
Well, we'll look into it.

[CLAIRE DITERZI'S
"LA VIEILLE CHANTEUSE" PLAYING]

Oh, I haven't seen those
since organic chem.

Natasha thought
you could induce CAA.

You think that's how you do it?

Certainly seems possible.

But this... Oh, don't touch.

Obviously this is a rendering
of a molecule,

but the elements aren't labeled,
so I can't tell which molecule.

Until I do, I can't say for certain.

She gave you a list
of the world's best geneticists.

Have you thought about
asking one of them?

You mean our pool of suspects?

Hmm.

If I haven't decoded
this thing by morning,

we'll send it to someone
unconnected with the case.

[TURNTABLE SPINNING]

[WATSON SIGHS]

I worked hard on that dinosaur.

I spent some time with that picture
Natasha sent last night.

I figured out most of the elements.

The rest I sent
to my old genetics professor.

In the middle of the night?

He has insomnia, so he's always up
between 2 and 4 anyway.

You were romantically involved
with your genetics instructor.

Jerry was amazed by this.

He said it was like looking at something
out of Leonardo da Vinci's sketchbook.

It's a man-made chemical
from the polycyclic hydrocarbon family.

It's like we thought.

This is a mutagen that targets
the stretch of the genome

that is responsible
for hereditary CAA.

That's quite beautiful.

So all we have to do now
is prove that someone paid a genius

to develop this
and then used it on Gerald Lydon.

That should be
a fascinating day's work.

It's cold.
Did you pick up my sweaters?

- Seriously?
- I will thank you

for the molecular formula
when I'm sufficiently warm to do so.

[SIGHS]

[MAN SPEAKING IN
FOREIGN LANGUAGE ON TV]

Hi.

[SPEAKING IN
FOREIGN LANGUAGE]

She say, "Wait one second.
Almost commercial."

[SPEAKING IN
FOREIGN LANGUAGE]

- She say she never seen you before.
- I'm here for a friend.

Wow, that's quite a coat.

It's warm.

[PHONE BEEPS]

Um, don't you want money?

[SPEAKING IN
FOREIGN LANGUAGE]

She says $75.

For four sweaters?

Okay, $19, then.

- Um, could I get a receipt?
- No.

GREGSON: So, Benny, you're saying
you were mad at Ms. Kademan.

BENNY:
Hell, yeah, I was mad at her.

I signed up for her study to get
brownie points with the parole board.

She called me
an incurable sociopath.

You think that didn't add time
to my sentence?

So you went to Ms. Kademan's office
a few weeks ago to threaten her,

- and last night you killed her.
BENNY: No.

GREGSON:
You don't have an alibi.

BENNY:
Yeah, but it wasn't like that.

What's with
Main Moon Dry Cleaning?

HOLMES: I'll admit the new
management isn't efficient,

but I find them charming.

That's Benjamin Cordero,

career blackmailer,
general blackguard.

Also innocent of the murder
of Natasha Kademan,

which I would very much like
to get back to solving.

BELL:
We don't need your DNA, genius.

You're a convicted felon.
We got a sample on file.

[PHONES BEEP]

Which means you got a very short
window to cooperate with us.

[PHONES BEEP]

So you wanna make a statement
or what?

[BANGING ON MIRROR]

You delay, but time will not!

That's a quote, Benjamin Franklin.

I know who said it. I don't know why
you're shouting it through the mirror!

This crime has
a certain elegance to it.

It involves careful planning,
scientific innovation,

a country home
in the Norwegian fjords.

That prosaic individual
has no place in it.

He had beef with Natasha Kademan.
He's been to jail for a stabbing.

Okay by you if we run his DNA?

It's not my place to tell you your job.

But by the time
you get your results back,

I will be that much closer
to proving that someone,

most probably Carter Lydon working in
concert with a Norwegian geneticist,

poisoned Gerald Lydon
with a hitherto nonexistent compound

and then murdered
Natasha Kademan

when she found out
what they were up to.

Oh, I take it back. Your version
sounds much more plausible.

Sorry, you think there's actually
something to my dad's story?

We do.

And we think that elements within
the company may be responsible.

- Elements? What elements?
- I'd rather not say.

What I would like is root access
to your company's servers.

We may be able to build a case
by tracking e-mails.

Uh...

I mean, I don't know if
I can do that, guys.

There are big changes coming here.

I don't know what job
I'll have next week.

We're talking about your father.

[DOOR OPENS THEN CLOSES]

My father doesn't need your help.

That's for him to determine.

- Thanks for your text.
- Mm-hm.

And actually
it's not my dad's decision.

He was declared legally incompetent
this morning.

Your services are no longer needed.
Get out.

Actually our contract with your father
calls for termination in writing,

countersigned by both parties.

Sign here.

WATSON: It worked.
The thing with the termination letter.

I mean, obviously we don't even have
a contract with Gerald Lydon,

but I noticed that Carter
bites his nails.

People who bite their nails tend
to chew writing implements as well.

Well, he never asked for it back.

You know,
maybe we can get a DNA sample.

If he killed Natasha,
then we've got him.

I just need a plastic bag.

Not a bad gambit, Watson,
though a hair sample would be better.

A hair sample?
What do you want from me?

Nothing. I have a sample already.

Carter, like many people
who slick their hair back,

carries a comb,
so I picked his pocket.

If you wanna be a detective,
you should get in the habit

of carrying evidence bags.

[PHONE RINGS]

Detective Bell.

We may well have cracked the case.

Benny Cordero's DNA came back
a match for the blood at the scene.

So I hate to burst your bubble,
but we're booking him for murder.

That's not my blood. No way, no how.
It's not even possible.

Look, we test 13
different genetic markers.

Every single one of them
was a perfect match.

Then somebody set me up.

- Look, I know this looks bad, but...
- Doesn't look like anything.

We know what happened. It's over.

What if I did have an alibi?

I live in this courtyard building
and the couple across the way,

they don't close their blinds
that much.

I notice stuff with the husband
and the nanny.

Just holding hands first,
then some kissing.

So the night the Kademan lady
got killed,

I got my camera out,
I put the zoom lens on...

So you're saying your alibi
is that you were home,

taking blackmail shots
of one of your neighbors?

Well, yeah.

Are these the same sweaters
I picked up yesterday?

You're a detective now. You tell me.

Yes, same sweaters.

You left them
outside my room by accident?

I was setting up to practice
my calligraphy at the same time

I was unpacking the dry cleaning.
There was a mishap.

We agreed that you were in charge
of the dry cleaning,

but we didn't say
how often you'd have to go.

Fine, well, I'm picking another place.

When they're your clothes,
go wherever you like.

My clothes have to go to Main Moon.

I'm sensitive to chemicals
in dry cleaning.

- They use only the gentlest emollients.
- Really?

Yes. Now, as much as
I love dry cleaning,

I'm trying to get some thinking done.

Oh, so you still think Benny Cordero
didn't kill Natasha?

Never mind the fact
that no one plans a blackmail

and commits murder
on the same evening.

The man has no connection
to the Lydons.

And his supposed victim texted us
the formula for inducing CAA,

and got stabbed 20 minutes later.
Can't be a coincidence.

I'm trying to think
of alternate explanations.

Possibility one is obvious, which is why
Mr. Cordero put it forth himself.

Someone got ahold of his blood,
then planted it at the crime scene.

Not unheard of,
but also an investigative dead end.

I can't prove that it didn't happen.
I get absolutely nowhere looking into it.

There's no evidence that anyone
other than Benny Cordero

was at Watt Helix that night,

which is why
I'm considering possibility two.

WATSON:
It's blank.

Possibility two has stubbornly refused
to reveal itself.

Well, keep staring at the wall.
I sure it's hiding in there somewhere.

[MAN SPEAKING IN
FOREIGN LANGUAGE ON TV]

Hi again.

Little accident with the sweaters.

Slow day yesterday?

[SPEAKING IN
FOREIGN LANGUAGE]

She say, "Why you ask that?"

So she understands English,
she just doesn't speak it?

I'm only asking because, uh,
that mink coat

is in the same exact place
it was yesterday,

so that means that hasn't been
turned on since I left.

[SPEAKING IN
FOREIGN LANGUAGE]

She say, "Slow day yesterday."

Do dry cleaners get robbed a lot?

I just noticed that you have six
very expensive security cameras here

and then two more at the front door.
Seems like a lot.

They came when we buy place.
Problem?

No, it's not... It's not a problem.

Thanks.

I figured it out.

I'm sorry to interrupt, but I know
exactly what you were up to.

I sincerely doubt that.
Would you excuse us for a moment?

There is a reason why
you sent me to Main Moon.

They don't do any business,
don't know how much to charge,

They have a load of security cameras.
There's something going on.

Watson, I admire your enthusiasm.
I have no idea what you're on about.

You wanted me to notice.

I wanted my sweaters.

Now, I know
I have counseled you to be alert,

but that doesn't mean that there is
a conspiracy lurking behind every door.

Okay, so, what are you up to, then?

After you went to bed,
I spent a good hour

trying to reckon how an innocent
man's blood could wind up

at the scene of a murder
if it wasn't planted there.

Then I remembered something
that you said.

The late Mrs. Kademan gave us a list
of the top geneticists in the world.

Why not ask them?
Everyone, say hello to Ms. Watson.

[PEOPLE ONSCREEN SPEAKING
IN FOREIGN LANGUAGES]

Good morning.

I left Dr. Moller from Norway
off the list.

Now, the others were
a bit confused at first,

but after I posed the problem
to them,

we had quite a lively discussion,
didn't we?

Yes. Turns out,
there is another possibility.

Jurgi, would you please explain
your breakthrough to Ms. Watson?

It's quite simple really,

though I should give you
a grounding in cellular biology.

Another time perhaps, Jurgi.

Actually, you know what?
I'll call you all back. Thank you.

He's a brilliant man,
little bit long-winded.

Gist of it is, law enforcement runs
a standard DNA test

called STR analysis.

It's actually a bit imprecise.

It tests 13 loci against each other
when there are countless possibilities.

All assembled agree that technology
has advanced to the point

where you could manufacture
a match of 13 loci.

So you're saying you can fake
a DNA sample?

All you would need is access
to a top-tier lab

and access
to someone's genetic code.

And I'm not just saying
that you could do it,

I just re-gathered my round table
to tell them that in this case,

someone did do it.

How could you possibly know that?

I called in a favor at
the medical examiner's DNA lab.

They provided a sample of the blood
found at the scene

of Natasha Kademan's murder
for a full workup.

A friend of Jurgi's at Columbia
handled the analysis.

All 13 loci tested in STR analysis were
a perfect match for Benny Cordero,

but there were no other loci
at all in the sample.

So you're saying someone stripped
a blood sample of its genetic material

and then created a match for the loci
they knew the police would check?

Only a geneticist
would be able to carry that out.

Well, seems like everyone connected
to this case is a geneticist.

But only one pointed us in the direction
of Benny Cordero in the first place.

GREGSON: So this morning
my consultant marches into my office

and says the damndest thing.

He thinks it's possible
to manufacture a DNA sample.

Thing is, he was right.

The blood that we found at the scene
of your fianc?e's murder,

it didn't belong to Benny Cordero.

It was just designed to look that way.

Well, that sounds kind of crazy.

Now, you work for
Ubient Pharmaceuticals, right?

I bet they have nice labs.

- What are you saying?
- Paul, come on.

We know the sample was faked.

We know you pointed us
at Benny Cordero in the first place.

We know you had access
to his genetic makeup via your fianc?e.

We know your employer
has probably the top lab in the city.

We also have a pretty good idea
of the equipment

you'd need to manufacture
a fake DNA sample.

Now, we can get a court order
to look at it,

but as it turns out, we don't need to.

We shared everything
we know with your bosses.

They gave us access.

Our crime scene unit is processing
the lab as we speak.

You may think
you've covered your tracks,

but if you made the sample there,
we'll find it.

Why did you murder your fianc?e?

[SCOFFS]

Right after we got engaged,

Tash and I had
complete genetic workups done.

Natasha asked them to check us
both for the warrior gene,

the gene that she isolated
in her research, just being thorough.

Turns out I have it.

My DNA says I'm a sociopath.

She said it wouldn't change anything,
but I could feel her pulling away.

Then the late-night phone calls started,
the long hours at work.

She was moving on.

Moving on and stepping out.

You think she was cheating on you?

A guy knows. And I even had a name,
Lincoln Dunwoody.

I knew that she was planning to leave
and she doesn't get to make that call.

So you're saying you murdered her
out of jealousy?

I guess I knew for a while
that it was gonna end like this.

That's why I made the blood.

But last Tuesday she called to
cancel our dinner date on my birthday.

That was it.

So where does Carter Lydon fit in?

The formula
for inducing hereditary CAA?

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

I'm talking about the plan to poison
Gerald Lydon.

Look, I killed Tash, okay?
I am telling you that.

But I don't know how to induce CAA.

I don't even remember
what it stands for.

[DOOR OPENS]

Hey, I caught most of the Reeves
stuff from the bullpen,

then Bell filled me in on the rest.

Look, I know you thought
it was all connected

and that finding Natasha's killer
was gonna help explain

what happened to Gerald Lydon,
but it didn't work out that way.

But we do have
a murderer in custody

and you got around
a fake DNA sample.

Strange name.

Did you know there's no one called
Lincoln Dunwoody

in the whole of New York?

At first, I thought
Natasha Kademan's paramour

was using a fake name
for their affair.

But when you separate the two names,
treat them as two surnames

rather than one nonexistent person,
you get a very interesting result.

This Lincoln family has a long history
of generous philanthropy.

So too does this Dunwoody family.

The Lincoln family's patriarch
is James Lincoln.

He recently retired after a sudden
and unexpected diagnosis

of cerebral amyloid angiopathy.

There's no history of the disease
in his family.

Huh.

That is weird.

I don't think Natasha Kademan
was having an affair at all.

I think she was trying to expose a plot
to poison these men.

Well, you only know
of two cases, right?

I mean, CAA is incredibly rare,
but that could be just a coincidence.

What if there was
a third person stricken?

- Is there?
- I don't know.

But I do know that a woman
called Greta Dunwoody

recently retired as president
of her family's foundation.

She's dropped off the society pages

and no one is quite sure
what's happened to her.

Well, we need to find her.

Apparently the family's keeping shtum,
but read the list of grants.

They just donated $20 million
to St. Bede's Hospital.

If she was sick, I would say that
would be a good place to start looking.

[PLAYING CHOPIN'S
"PRELUDE IN B-MINOR" ON PIANO]

Ms. Dunwoody?

They told us we'd find you in here.

These are for you.

They're beautiful. Thank you.

You're not my son, are you?

No, we just thought
we'd check in on you.

Oh, that's nice.

Do you mind if I practice?

I have to keep practicing
if I want to get into Juilliard.

[RESUMES PLAYING]

Amazing.

The brain decays,
but muscle memory remains.

Gerald Lydon wasn't the only target.

Someone's poisoning these people.

WATSON:
You're cleaning the fridge out now?

It's my half of our agreement.

Well, I was hoping
you could help me figure out

who's giving rich people CAA.

Yes, that was first on my list,
now the refrigerator.

You have a suspect. Who?

You're a detective. You tell me.

Fine. Um...

Okay, it's not Carter Lydon.

I mean, he has motive
to want his father sick,

but he has no reason
to attack strangers.

Maybe he cosigned that loan
for that guy in Norway

because he wanted him to help
with his father's case.

So who does have motive to attack

three seemingly
unconnected strangers?

The victims are three rich people.
They all have charitable foundations.

The only people that would benefit

from wealthy philanthropists
coming down with CAA

are the people raising money
to study the disease.

Induce CAA in some
of New York's wealthiest,

then sit back
and wait for donations to flow in.

Not all the victims would contribute,
so you'd have to dose more than one.

Did you know the Lincoln Foundation
gave a rather generous grant

to the research labs at Watt Helix?

Natasha's company.

She was a whistle-blower.

There's gotta be, what,
50 people working in research there?

But how many of them are capable
of inventing an entirely new molecule

which attacks a specific gene?

Well, it's gotta be
the smartest person there.

Of course.

That person might not still work there
on a daily basis.

Mr. Watt, did you know
that before Ms. Kademan was killed,

she was working
to expose a scandal?

It's quite a story.

She thought that someone
at Watt Helix

was inducing mutations
in wealthy people

to attract funding
for research into CAA.

- We think she was right.
- That's shocking.

I assume you have evidence.

Whoever developed the molecule
was brilliant.

A towering intellect.
Someone a lot like you.

ATTORNEY:
I hope that's not an accusation.

Brian Watt is a decorated physician.
He has a sterling reputation.

Why would he risk that
for whatever you're describing?

We spent a good deal of time puzzling
over that ourselves, didn't we?

Yeah. We came up with a theory,
but we couldn't be sure of it

until we got a good look at you.

You have hereditary CAA,
don't you, Mr. Watt?

That's why you're semi-retired,

and that's why you haven't said
a word since you came in.

We know it's in your family.

Probably why you got into genetics
in the first place,

find a way around the death sentence
that you carry in your DNA.

But you got sick,
research wasn't going fast enough.

So in your more lucid moments,

you hatch a plan to attract bigger
and bigger money.

All you'd have to do is to introduce
the chemical you developed

into someone's IV.

All the victims had procedures
at Stuyvesant Memorial,

a hospital
where you still hold privileges.

You're wrong.

Well, then you won't mind if we take
a look inside your home, will you?

Because there won't be any more of
the chemical needed for further attacks.

We have a team of detectives
heading to his home as we speak.

MAN [ON TV]:
Entrepreneur Dr. Brian Watt

has been charged
in a bizarre string of poisonings.

- Watt was arrested this morning...
- Hi there.

Are my sweaters ready?
I didn't think so.

This is Detective Bell
from the N.Y.P.D.

I told him about the world's worst
dry cleaner's and he got curious.

You know who bought this place from
the Korean couple who used to own it?

It's a shell company.
I can't even pronounce it,

but my friends at the N.Y.P.D.
Know all about it.

They think it's linked to smuggling,
human trafficking, other fun stuff.

So now I know why
you're so terrible at dry cleaning,

because the only thing your owners
want you to clean is their money.

BELL: And given all the security
cameras you have in here,

I bet if we execute this search warrant
we brought with us,

we'd find plenty of it. Is that true?

[SPEAKING IN
FOREIGN LANGUAGE]

OFFICER 1:
All right, come on. Let's go.

- Hands behind your back.
OFFICER 2: Come with us, please.

Put your hands behind your back.

- I did it!
- Close that door immediately!

- What's up?
- I was examining the Osmia avosetta

that Gerald Lydon gave me
and it got loose.

Oh, so there's an almost-extinct bee
flying around in here?

Yes, and I would rather
it didn't get out.

Okay. Well, I took care of it.

That dry cleaner you sent me to,
you deduced what they were up to.

Bell sent in somebody to search it
and everybody's arrested.

Thought I'd have to send you back there
three times more times. Well done.

Why didn't you tell me
when I came to you yesterday?

I wanted you to learn to trust
your own instincts.

A good detective knows
that every task, every interaction,

no matter how seemingly banal,
has the potential to contain multitudes.

I live my life alert to this possibility.

I expect my colleagues
to do the same.
