All language subtitles for CSI.Vegas.S02E13.Boned.720p.AMZN.WEBRip.DDP5.1.x264-NTb

Previously on CSI: Vegas...

Folsom and I found an old dossier

along with this note.

Dr. Auerbach.

You think this one little doodle

means that she's behind
all these killings?

Didn't she say whoever's behind
this might be playing games?

Maybe that's exactly what she's doing.

Lynn Zobrist and another
victim Lamont Moore,

they all have scars on their temples.

Maybe the other victims have suffered

some serious psychiatric problems, too.

I spent some time in a facility.

There were mirrors there?

There were mirrors everywhere.

I'm not going back in the field.

I'm either in the lab or I'm nowhere.

All right now.

Shake, shake, shake.

Take those lights off. Yup.

I think we're getting it.

I don't think we're getting it

until we've, you know, struck gold.

Now remember,

you're looking for the black sand.

'Cause that's where the gold be.

Well, I, for one, am having a lot of fun

on our little adventure.

A day at the pool can be an adventure.

A beautiful, air-conditioned restaurant.

Cirque du Soleil.

Billy and I are having
fun. Aren't we, Billy?

Sure.

Excuse me, miss.

This area isn't safe.

There was a flood here yesterday.

The ground is very soft and can...

Right this way, guys.

Bodies are just up here.

Then why'd we have to
park way back there?

Do you know how far I've
had to carry this thing?

Really far.

Really, really far.

Really?

Well...

It looks like our bodies
are more like one body

and two skulls.

Most of one body.

Left leg's been severed
just below the patella.

We got different rates of decomp here.

Look.

There's still some skin on this fellow,

whereas here...

She's nothing but bone.

Maybe the coyotes found
her especially tasty?

"She"? "Her"? How can you tell?

Well, just a guess based
on the cranial vault.

Forehead angle is vertical,

not receding,

and the supraorbital
margin is sharp, suggests

sex is likely female.

Late teens, early 20s.

You okay?

Yeah.

Okay, jackpot.

Gentleman with the missing leg is...

Harrison Cantwell.

Okay if we roll him?

Yeah, go ahead.

Whoa, hold on.

Got some kind of stone here.

Looks like he got it
in the chest a few times

- before they stabbed him in the eye.
- Oh.

These guys like to hide

in bodies that have
been out for a while.

The bluebottle flies come and go.

And then the coffin
flies have their turn.

And then beetles.

- And tarantulas.
- Yeah, tarantulas eat the beetles.

So this guy's been missing...

40, maybe 50 days.

Yeah.

Wonder where they came from.

All right, Penny.

What do you see? No
presumptions, no guesses.

- Come on.
- I need space, I need space!

I don't want you reading my thoughts!

I'm having a hard time focusing

on what I see because what I hear

from over there is really distracting.

You're listening to my thoughts.

You're making me sick.

Penny, look at me. Look at me.

Tune it out.

What do you see?

Okay, this guy drove up in a hurry.

He blocked the homeowner's car in.

Brought his gun to the front door.

But when the homeowner
Molly Tate opened it,

she was armed, too.

She fired three bullets.

They struck him in his chest.

Backspatter and expiratory

on his closed fingers
and the gun suggest that

he was holding his gun up,

- aiming at her.
- Mm-hmm.

Till boom, boom, boom,

he falls back, collapses and dies.

It looks like self-defense.

Yep. Well spotted, I agree.

Ms. Tate's self-defense story holds up.

Uh, Antonia?

I want to go back inside,

I don't want you listening to my mind.

Wait, wait, wait, stop.

That scar on your temple.

Did you get any of your
therapy in a mirrored room?

How could you know that?

Have you been in my mind?

Have you? Has she? Has she?

Has she? Get off me.

We've got to check this dead man's car.

Now.

Ooh.

This scene is all kinds of bad news.

Definitely.

Am I, uh, clear to remove this here?

Yep.

Hey. Did I miss all the fun?

Is that a spearhead?

Wait, do we need to contact
the Bureau of Indian Affairs?

Uh, no, I don't think
they have jurisdiction.

This isn't Shoshone, Paiute or Washoe.

This is something much
older. It's a Clovis point.

They date back like 12,000 years ago.

End of the Ice Age.

Am I crazy,

or does this look like a
type match to the other skull?

It might be an age match, too.

The wear on the bone, the teeth...

I mean, we'll need radiocarbon
dating to confirm, but

it's possible this skull
dates back that far, too.

Okay, what are we saying?

I think we're saying...

these two lovebirds were killed
with the same murder weapon

12,000 years apart.

So, we got a new dead
body and an ancient skull.

Listen, Cantwell's
fingers were curled inside

the skull's occipital opening.

And rigor set in, just...

He was locked on tight.

Yeah.

Like an action figure
with a kung fu grip.

So, he holds on all the way downriver,

but...

- Wondering where he came from?
- Yeah.

He could have floated quite a ways.

W-we got a heavy rain last night.

This watershed is very
prone to flash-flooding,

especially in the middle of this

drought season that we're having.

Is that right?

My-my point is,

he didn't get killed at
Flash in the Pan Tours and...

Well, maybe she can pass that along

to any reporters who might be wondering.

Okay, Mr. Jakes. Thanks.

You can go.

All right, so I did some googling

on our victim Harrison Cantwell.

Apparently, he was some sort of

amateur archaeologist turned author.

Well liked, did a lot
of philanthropic work

for museums around the world.

Semi-famous in nerdy circles.

Oi. I've heard of him.

Yeah. Now, he's from New York,

but he's got an honorary seat

on the board of the Natural
History Museum of Clark County.

Maybe that's what brought him out here?

Well, I was heading there next anyway.

They have the equipment I
need to carbon-date the skull.

So, you... the body
and the murder weapon.

You... the ancient skull.

And another thing. Come here a minute.

- That 419 this morning?
- Mm-hmm.

In the dead man's trunk

was a card written in silver ink.

"Keep your secrets.
Cull the rotten fruit"?

It seems like

he was sent to kill this young woman

and she wasn't having it.

Then this would-be victim,

she could be another link in the chain.

- I need to talk to her as soon as possible.
- No.

We need to walk and chew
gum at the same time.

I will stay on your silver ink case

'cause I need your expertise
on this ancient skull business.

Thank you. All right, y'all. Come on.

More than an author.
He was so charitable.

So kind. Like a brother to
all of us here at the museum.

Are you sure it's him?

- Wow.
- You all seem surprised.

But from what we can tell,
he must've been missing

for close to two months.

Cantwell wasn't a
traditional scientist per se,

but he was passionate.

He immersed himself in research.

Before his last three
books, he went off-grid.

Five, six months.

Embedding, searching.

No one ever thought anything of it.

Zimbabwe, the Yucatán.

This last time, he was
looking for Clovis artifacts

in the Basin and Range.

Well, he might have found
more than just artifacts.

Um, there was a Clovis point,

a murder weapon that
we took back to the lab.

But there was something else.

Here, have a look for yourself.

What in the world?

Tad, run and get my hand lenses.

Do you think it's possible?

That this is a Clovis skull?

It-it would be the find of the decade.

Wear on the bone,

the teeth, it certainly could be.

We have so few

links to the oldest humans
to walk on this continent.

Someone has to write this up.

It should really be you.

Perhaps Tad can assist.

For now, I'm assisting. We need it.

It's part of a homicide investigation.

Our lab can handle tool mark
analysis on the Clovis point,

but do you happen to have

a, um, accelerator mass spectrometer

for carbon-14 dating?

Mm-hmm.

Do you mind if I play with it?

We're trying to find out
if she and your friend

were killed by the same weapon.

River was beautiful this morning.

Sun was shining. Here?

And you probably saw the pictures,

but it really does not do it justice.

- This?
- Yeah, that, too.

I mean...

the lab is great. There.

But, uh...

field work is great, too, man.

I just wish you
could've been there, man.

I'm a lab rat, you
know, now and forever.

11 points of minutia
on the Clovis point.

11 matching points on
the defect in the skull.

They-they measure out perfectly.

- Yeah, it's a match.
- Yeah.

Looks like there's some little
fragments from the arrowhead

that were broken off
in the skull itself.

No weathering on the broken edges

means it was probably
pulled out recently.

Like, maybe right before the attack.

What if this is what
they're fighting about?

I mean, it could be, they know
the value of these artifacts,

I mean, if they're as old
as Allie thinks they are.

Oh, they are.

Radiocarbon dating says this skull

is 12,245 years old.

Give or take.

We're talking 10,000 BC? Wow.

That's older than agriculture.

I know.

So, Harrison Cantwell
managed to find a skull

that had been hidden from
humanity for 12,000 years.

Wherever he found it, that's
got to be our crime scene.

Yeah, it's taken since the end of
the Ice Age for someone to find it.

Yeah, well, I'm sure we'll have
it sorted by lunchtime tomorrow.

Okay, okay. Okay, okay,
okay, goodbye, Sonya.

No, you are. Mom agrees.

Yeah, kisses.

Hey, Jack, is your sister out of town?

She's in London presenting a paper.

"Sudden Death and
Fibromuscular Dysplasia

of the Mesenteric Arteries."

I've seen her slides.

They're really funny.

- You knew about this?
- Yeah.

She asked me for kebab recommendations.

Don't worry.

We FaceTimed our way through
a very thorough intake.

- Mm.
- Ready for the highlights?

Our victim was stabbed five
times using a stone object.

Probably held in the hands, not a spear.

The wounds are too shallow.

The final stab into his
eye isn't what killed him.

This wound, in the
inferoanterior cardiac muscle

near the right ventricle, caused
a hemorrhage into the torso.

Broken bones in the arms
and jaw suggest fistfight.

Broken carpals and
metacarpals. He fought back.

And what about the leg?

Uh, leg.

- Jack?
- Ah!

Right. If you look at the
position of the cartilage,

definitely postmortem.

My guess is some kind of animal,

like a coyote, tugged at
it till it was torn off.

What about this?

Huh.

Looks like... sand?

Maybe? Stuck to the hardened earwax?

There's quite a bit of it, especially...

given the advanced
state of decomposition.

Meaning what?

I don't know yet.

But this kind of eluvium might tell us

where Cantwell was before he was killed.

I don't want you pulling
thoughts out of my head.

- You're scaring me.
- But, Molly,

you're not being charged.

We know you acted in self-defense.

Your doorbell camera,
it got the whole thing.

Then why am I here?

You trying to put things in my mind?

- Hmm?
- No, we... we can't put things in your head.

We just want to ask you some questions

to help keep you safe.

I told the cops.

I'm not going into...

protective whatever. I'm fine.

But whoever came to your house,

they came with a specific
intention to kill you, Molly.

Do you know why?

No.

I don't.

I don't have any idea.

For all I know, it was you.

I know this is very hard.

But we have to talk about this

because we don't think it's over.

- Wait, what are you... ?
- Just listen.

There have been a
number of recent crimes.

And in every case,

the people who were being targeted

were being encouraged
to kill someone else.

You got a card.

Just like this, Molly.

- Didn't you?
- No.

I didn't.

I didn't!

You two are listening to my thoughts.

Which I asked you very clearly

- not to do.
- Molly.

We cannot listen to your thoughts.

You got a card,

and it came with a dossier.

Blackmail.

You were being asked to kill someone.

We're just trying to keep 'em safe.

That dossier could tell
us who's behind this.

I don't want to be here.

Am I free to go?

Am I?

Yes, of course.

Listening to her damn thoughts.

If I could hear her damn thoughts,

this case would be over by now.

That's thought broadcasting
and thought insertion.

They're common delusions for people

with schizoaffective disorder.

If we're gonna learn anything
about who sent this card,

it's gonna be from this card.

Okay, remind me again
what we're doing out here?

This is fun.

Admit it. Come on.

No. Fun is tequila shots

and blowtorch queso.

This is...

Dude, this is Duck Dynasty.

Let's just get this over with

- so we can get back to civilization.
- Okay, look.

So, this is where our
victim washed up, right?

But it's not where he died.

So, if we're gonna find
what happened to him,

- we're gonna have to retrace his steps.
- Retrace his float.

All right, so...

Guy was on dry land for weeks.

Long enough for those spiders

to take up residency in his torso.

Then the rain came and brought him here.

But it was only raining
about four hours, so...

How far does a guy float
in about four hours?

You know, I have a
tool that can tell us.

He's a very specialized CSI.

- Ready, Folsom?
- Let it rip.

All right, ready?

Okay, so most objects on the
river move at the same rate.

The increased flowrate
after last night's rain...

we'll call it 1.6 to two miles per hour.

The body must've floated...

six and a half to eight miles.

I'm not walking that.

Don't worry, me neither.

This is six and a half miles.

Whoa, hold on...

Is that... ?

A shoe?

Well, this isn't great.

No blood.

There's no signs of struggle, either.

Hey.

I found our tibia.

So, this must be the spot
where our victim's body lay

all that time before the flash
flood washed him downriver.

But this isn't a murder
scene, this is just...

A shoe and half a leg.

Okay...

if this isn't where

the murder actually happened...

... how the hell are we going
to find the crime scene now?

Okay, so, uh...

Cantwell makes this big-deal
archaeological find somewhere

in this valley, then...

gets stabbed and winds up here.

Well, he was either dragged
here by his killer...

Or he limped out here
under his own power

when he had both his legs.

Either way,

desperately holding on to that skull.

Well, it sounds like
for an archaeologist,

this would be a career-defining find.

Anyway, there's-there's
still one silver lining.

What's that?

Well, this isn't the first time
I've found two skulls at a scene.

But it is the first
time I've only been on

the hook to solve the
murder of one of them.

Is there something about this
case that's bothering you?

No, let's just go solve it.

Okay, let's...

We need to keeping searching this area.

Aw.

Oh, she's been out here for a few days.

Why would somebody shoot her?

Well...

Maybe they saw she had a
person's leg in her mouth

- and they thought they might be next.
- Ugh.

I think this must be Cantwell's foot.

She's got a collar. That's weird.

GPS tracker.

Tagged wildlife.

Biologists use these to
track migration patterns.

If the coyote picked up
Cantwell's blood trail

at the crime scene
and followed it here...

Then this little gizmo might
lead us to where he died.

Stick with me because we've
got a lot of trains running.

First, we've got these postcards.

This one was in Alan Herskovitz's house,

in that first case that
kicked off this whole mess.

This one was sent to us last week.

Then we have these cards.

Same card-stock, same metallic ink.

The only DNA and fingerprints

we found on the ones from yesterday

are from Lukas Tremaine,
the man that Molly killed.

But none from whoever sent them.

What I don't get is

why write these out by hand
and then print these out?

What is that about?

Maybe his computer doesn't have

his favorite "Wacky Scribbles" font.

I always go with "ancient
alien hieroglyphics"

when I'm encrypting
my demented ramblings.

That or Helvetica.

Presumably you all came in here

- to tell me what you learned.
- Yes.

This card was printed on
a consumer inkjet printer.

Make and model?

Still working on that.

But get this:

the ink he used contained real silver.

Which is not a good idea.

Those tiny flecks are pointy.

So they leave tiny microscopic
punctures in the print head.

So when you look up close?

It makes the same error

over and over and over and over again.

- Exactly.
- So, whoever's behind all these murders,

everything they print will
have these distinctive errors.

Because the printer has its
own distinct "fingerprint."

Nice catch.

It's a start. I'd like to review
more material he's printed,

but the only people who got some are

either in a mental
hospital, in prison or dead.

Except our dear friend Molly.

Who I would really like to talk to.

You know, Molly is a tricky one.

I asked LVPD to put a
car outside the house

because I got to talk to her again.

Okay, well, I could go with you.

Mm, nah...

I think the rest of your
afternoon just walked in.

Hey. Folsom. What you got?

Dead coyote.

Ooh-ooh.

Really appreciate you coming
all this way, Mrs. Cantwell.

You know, I'm sorry to have
to ask all these questions.

It's perfectly all right, Detective.

Anything I can do to help.

Now, we've heard your
husband would go on

extended research trips for his books.

Did he generally keep you in
the loop on his whereabouts?

Well, it's somewhat embarrassing,

but I don't remember the last
time Harrison and I spoke.

He always had his satellite phone

in his bag, but typically he kept it

powered off to conserve the battery.

There's something that I'd like
to ask of you, if that's possible.

Fire away.

Has the medical examiner given
an official cause of death?

Now, I only ask because I'd like to have

the death certificate expedited.

For legal reasons.

"Legal reasons"?

Can you tell me a little
bit more about what you mean?

Well, I've always had to
manage Harrison's business

and I've always had
to move money around.

Those month-long walkabouts
are pretty expensive.

Every dollar that came
in, it went right back out.

- We were always funding the next one.
- So...

from a financial point of view,

his death might've actually
saved you some money.

That's one way to look at it.

Hmm.

Beau?

Beau.

You all right?

- Yeah. Sure. Yeah.
- Really?

Don't know.

You seem less yourself lately.

Did I miss a memo or something?

Folsom was all over me, too.

Sorry.

We all see it.

You know, when you first came to CSI,

you had a new lease of life.

But ever since you've
retreated to the lab...

I know it sounds simple.

"Just get back out there." But...

The world outside of these
four walls is terrifying.

I mean...

under this powerful mustache,

is a sensitive soul, Allie.

Okay.

Look, when you're ready,

I'm here for you.

Okay.

Silicon dioxide, alkali
feldspar, plagioclase.

I mean, if you put them all together:

that's got to be granite in Mr...

Mr. Cantwell's ear.

Granite. You just know that?

Oh, I had the world's
greatest geology professor.

Dr. William.

And if I remember his class correctly,

there shouldn't be a ton of
granite in this river valley.

It might tell us something
about where he was digging

when he got attacked.

I need to get some geological maps.

- Oh, and Allie?
- Mm-hmm?

Thank you.

Okay, so...

these are the places our coyote walked

in the weeks and months
before she was shot.

Well, I found granite
in the victim's ear,

but granite isn't found
in the river itself,

just the tributaries...
these five are the closest.

That cactus needle you found on the shoe

is from a cactus called
opuntia basilaris.

Typically found at
elevations above 800 feet.

Okay, well, let's see.

Our coyote only visited
one of those tributaries

in her final days, which
should put our mystery site...

Around here. Near that
little branch in the river.

"X" marks the spot.

Hey, Al.

You're never gonna believe this.

It's Harrison's dig site.

This is major.

The skull alone was a big find, right?

I don't think anyone has
ever found a Clovis skeleton

this complete before.

This could end up in textbooks.

I doubt the textbooks will include this.

This site wasn't just why
he was killed, it was where.

There was a fight to
the death, right here.

We finally got our crime scene.

Serena. What's going on with you?

Is there something about all
this that's bothering you?

I told you I'm fine.

Okay.

Listen, if you need to talk...

Josh, drop it, okay?

This dig, just underway.

But already it's incredibly exciting.

Harrison Cantwell's
got to be excited, too.

Until it got him killed.

It happened right about
here, if I had to guess.

It's the highest concentration
of blood left out here.

That's pretty funky, right?

It looks like blood's been cleaned off

with hydrogen peroxide.

Ooh-whee.

That means somebody was clever.

DNA shrivels and dies at the
feet of hydrogen peroxide.

Pulling alleles out of
that is gonna be a struggle.

Hey, guys?

Nice find, Serena.

Couple calls to his wife Rose.

The last call was made...

47 days ago. Two minutes and change,

to Dr. Qadiri's office,
Natural History Museum.

If he told her about this find,

control over the site
is certainly something

two archaeologists might fight over.

I think it's time Dr. Qadiri
gets a second visit, huh?

You want to join us?

You know, I'd love to,

but I've been invited to meet a
bunch of fish at Molly Tate's house.

Lori, Nora, Luke, Violet, Chloe.

Melissa, Bill,

- Greg and Stacy.
- Yeah.

You decorate these yourself?

Yeah, I like fish.

There's no stress in them.

And they can't hear what I'm thinking.

I know.

I know how all of it sounds.

Yeah.

Feeling like people can hear
your thoughts does sound...

a little stressful.

And lonely.

I tell myself no one can read minds.

A part of me thinks...

"No, it's true, they can."

Sitting here, I-I'm worried

you're gonna hear the wrong thing and...

lock me up for good.

But your fish don't do that.

A couple months back...

I was attacked.

And afterwards...

I mean, I knew the person was gone,

but I still got nervous.

It's just... It is hard.

It's hard when you can't
control your thoughts.

You don't seem nervous now.

The person that, uh, hurt
me, they're behind bars now.

I killed my guy.

So I'm safe now, too.

Molly, you know you don't believe that.

And neither do I.

Honey...

- You need to be put in protective custody.
- I can't.

- I don't... I don't want to.
- The man who came here to hurt you,

he was sent here by someone.

Someone who also sent you a dossier.

And a card with silver ink, Molly.

Silver ink. Silver ink. I don't know.

I don't know, I'm scared!

We all get scared sometimes.

But the person who send you that dossier

and that card with the silver ink,

they left something on it.

I can find it...

if you let me.

I've been so tired.

Silver ink. Silver ink.

I'm gonna trust you.

Find him, please.

Come here.

Hey, Detective, you're back.

We need to speak to Dr. Qadiri.

I-I think she's in her office.

There-there's nothing wrong, is there?

I don't know yet.

Would you mind taking us back?

Of course. Uh, right this way.

That's strange. Uh...

This-this door is never
locked during business hours.

But, um, here.

Used to be my office, I can...

let you in no problem.

People are in and out of here
for supplies all the time.

Hey, this has Rose Cantwell's
name on the return address.

And it's postmarked after Harrison died.

Did Rose mention that she
was friendly with Dr. Qadiri?

Uh-uh.

Huh.

It's open.

By the looks of it...

she sent Qadiri some...

of Harrison's notes.

I'm also seeing what looks
like two sets of handwriting.

You think Dr. Qadiri
and Rose were planning on

getting rich off his big find?

I mean, it was brand-new dig
site, it was barely developed.

I doubt the killer counted on Cantwell

making a run for it after
being mortally wounded.

If they had hopes of
taking credit for the find,

they might've been
waiting for him to pop up.

- What are the odds?
- If there's one thing

I've learned since I moved to Vegas:

don't put anything past anybody.

Especially when it
comes to getting rich.

See what you can get off of that.

Hey, guys.

So, Max took a crack at
finding DNA in that blood

that we found at the scene.

No dice.

Hydrogen peroxide stays undefeated.

We're having better luck here.

Fingerprints from both Rose Cantwell

and Dr. Laura Qadiri on
Harrison Cantwell's notes.

Both of them were working together,

and yet both of them
failed to mention that.

Time for a little dueling banjos.

Maybe both of them ought to
come have a chat about it.

I'd like to see them deny it.

No, you're right.

Dr. Qadiri and I were working together.

We started a few months
before Harrison was killed.

Rose is a brilliant prose stylist.

She was pushing Harrison to
the next level of his career.

Laura brought extensive archaeological

expertise and credibility, which
Harrison was frankly lacking.

Harrison, Rose and I had a deal.

I'd help research the Cantwells'
book, write the foreword.

In exchange, I could publish
anything Harrison found

in the academic press, as lead author.

Well, why didn't you
mention this earlier?

It's not like we're hiding anything.

All of this had Harrison's blessing.

It didn't seem particularly
relevant to your investigation.

We found Harrison's satellite phone.

And the last call he made
might've been the day he died.

Can you tell us where
you were on January 9th

at 1:30 in the afternoon?

Where were you...

on January 9th at around
1:30 in the afternoon?

He had just made the find of a lifetime.

He called it in.

And one of you killed him for it.

Wait, wait, wait, stop.

Just... Just hold on.

January 9th? I was
traveling that weekend.

A lot of people saw us.

Saw who?

You and Dr. Qadiri
were both in Illinois?

In point of fact,

we were together.

I hate to say it, but
I-I think our theory

is kind of falling apart.

Oh, no, it's really falling apart.

Laura and I were in Chicago
to speak with a publisher.

The meeting fell through,

but we were there until Wednesday.

What...

Was th...

Do you think that's when he was killed?

Right after he made the find?

I didn't know.

I know you found their
prints on the same

- manuscript pages.
- But...

- they're still on the same page.
- Mm-hmm.

- Same story. Same alibi.
- Mm-hmm.

And you've got the same problem.

No hard evidence.

Any of y'all want to call
it a night, feel free.

Come on, boss.

This is our chance to
drink mediocre coffee

- at 2:00 in the morning.
- Yeah, was your chance.

I can't stop thinking about
Cantwell's last phone call.

I mean, two minutes and eight seconds.

Someone at the museum answered,

talked to him and turned him
into a hotel for tarantulas.

Well, there had to be

a lot of young and hungry archaeologists

at the museum who would do anything

to lay claim to the
discovery he made, right?

Logan MacArthur said everyone
had access to the office

where the call came in.

It was never locked, so

tying to someone specific
is gonna be tricky.

Actually...

there might be someone we
can tie to the crime scene.

Do we still have that
blood sample from the rib?

- The one that killer cleaned up?
- Oh, yeah.

We got lots of blood.

- No DNA to speak of, though.
- If I'm right,

we don't need DNA.

- Blood.
- Thank you.

Wright stain.

Well, red blood cells look normal.

These are different kinds
of white blood cells:

you've got neutrophils,
lymphocytes and monocytes...

There are four different types,

but we're only interested in one:

the basophils.

And basophils are the
markers for this disease?

Mm-hmm. And when there are no basophils,

there are a lack of histamines.

I guess if all this blood work

helps put the killer behind bars,

at least they get a
free diagnosis out of it.

- I'm not seeing any, are you?
- Nope.

The person who left their
blood at the crime scene,

all their histamines were stuck
to the underside of their skin,

which means...

Our man has cold urticaria.

Our man? We got him?

We got him.

There you go, Mr.
MacArthur, nice and cold.

I want to help you all
in any way that I can,

but...

... frankly, I-I'm
not sure why I'm here.

On the day he died,

your friend Harrison
Cantwell made a phone call.

The last one he'd ever
make. To Dr. Qadiri's office.

Your old office. Now, you're
in there all the time, right?

You admitted it yourself.

I'm not sure what
you're driving at, but...

I didn't speak to Harrison.

Yeah, you did.

Your pal Harrison, he told
you about his discovery.

A career-making find.

So you raced out there
and found out it was true.

A man who was not a scientist

had discovered something

you never could.

And he was on his way
into the history books.

You argued. You fought.

You got injured,

your resentment boiled over,

and you stabbed him.

But you were too hurt to follow.

How am I doing so far?

You want to show us your scar

where you got impaled on that rib?

I loved Harrison.

Uh, I wouldn't hurt a bug,

l-let alone a... a great thinker,

a-a great friend.

You don't have any proof of any of this.

Uh-oh.

What's-what's that there?

N-nothing. Just a nettle rash.

I-I get it sometimes, because of cold.

I know.

Your "nettle rash" is
actually a minor immune disease

called cold urticaria.

- If you say so.
- Oh, we do say so.

That's actually how we know
you returned to the scene.

And cleaned the bones
with hydrogen peroxide.

I mean, that was very smart.

It was.

Because it took care of all the DNA.

But it did not destroy the blood cells,

or the telltale signs of
the disease they're fighting.

Sir, the killer had cold urticaria.

The same thing Ms. Rajan noticed
that you had back at the museum.

I... I-I...

I didn't want any of this.

I-I was just upset.

He-he was going to take credit.

It was all an accident.

- I'm sorry, this is about credit?
- You wouldn't understand.

50 years I-I've worked.

I-I've never had a find like that.

Harrison w-would've never

found that site if it
were not for my help,

my museum's resources.

He had his whole life ahead of him.

He could've shared this.
He... he could've made

- a hundred new discoveries.
- No, he's not going to.

Not now.

Hands behind your back.

Stand up for me.

Poor gal got a spear stuck in her craw.

Yeah.

What's stuck in yours?

It's nothing.

You know what?

A few weeks ago,

you asked me what was wrong.

And I told you.

Back in Miami, when I
first made detective,

I got a case.

16-year-old runaway,

disappeared from a
motel room in Opa-Locka.

A little keychain like this
was the only thing left behind.

Until about a month
later we found her skull.

Just her skull.

I was green, so I thought if I just

worked the case hard enough...

- But that's not always how it works.
- Mm-mm.

It's a hard lesson.

I mean, we can't always
find the bad guys.

But her family...

Her family saw you try, right?

That matters.

Only so much.

Only so much.

Hey.

You ready to hit the road?

Yeah.

Have a good night.

- You go through Molly's dossier?
- Yep, fully processed.

453 pages of blackmail material.

It was really interesting.

Not the what, but the how.

When I found Lamont Moore's dossier,

it showed that he was
being coerced by photos,

electronic surveillance.

Molly's was different.

A few years ago, she confessed
to a few non-violent crimes.

But not to her diary, not to police.

To her therapist.

Why do I feel like I know
exactly where this is headed?

Okay,

- look at the handwriting.
- Mm-hmm.

Molly's blackmail material.

And then Dr. Auerbach's notes

from Lynn Zobrist's therapy sessions.

We got get this by a jury, all right?

Handwriting analysis is way
too shaky to hold up in court.

We won't need to build
our case around that.

- Tell me.
- Okay.

Dr. Auerbach's notes, which
by law, only she can have,

were printed on the same printer...

that produced these cards.

They all have the same flaw.

Our mastermind's digital
fingerprint is on all of them.

The sick mind behind
all of these murders...

... is Dr. Diane Auerbach.

Has to be.

Has to be.
