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.

Resync By M_I_S www.opensubtitles.org

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.

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.

♪ Who... are you? ♪

♪ Who, who, who, who? ♪

♪ Who... are you? ♪

♪ Who, who, who, who? ♪

♪ I really wanna know ♪

♪ Who... are you? ♪

♪ Oh-oh-oh ♪ ♪ Who... ♪

♪ Come on, tell me who are you, you, you ♪

♪ Are you! ♪

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,

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? GILL: 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

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. CHAVEZ: 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.
