Yeah, so Lindsey's a little tired.

you think this one little doodle
means that she's behind all these killings?
I'm not ready to say that, yet.
But look at it, Max. That was in her notes.
ROBY: It does look like all those silver glyphs
that've been popping up.
What's her explanation for this?
She's out of town,
at a psychiatric conference until Thursday.
You ought to meet her at the airport,
see what she has to say for herself.
Catherine. You look rested.
Must've been that morning I took off.
Sorry about that.
Um... but there's this case,
actually, an old case,
and you're gonna want in on it.
It's old, but it couldn't wait until tomorrow?
It's waited four years.
The incident happened January of 2019,
and CSI never investigated it.
I don't understand.
A crime during my tenure?
Coroner said noxious fumes
from a hair treatment killed this woman
and that her sister slipped into a coma.
This is my handwriting.
I remember this.
It happened the same night
as a major pile-up on I-15.
Remember? And-and folks here were just stretched thin.
No signs of forced entry.
LVPD let it drop. You know how it is.
Not every borderline case gets the full-court press.
This file hasn't been touched in four years. What changed?
During those four years,
Mimi Kahn was in a coma.
She woke up two days ago.
She says that her sister's death was not an accident.
And they are exhuming the body as we speak.
Well, I want to talk with her.
Kind of thought you might.
HANNAH: Peekaboo!
Rarr!
Catherine. She's adorable.
Right? Hannah,
I have to take care of one more thing, okay?
So, um...
since you're between cases,
could one or both of you keep an eye on Hannah
just for a little while?

FINADO: Okay, be prepared.
Oh, nope. Mm-mm. Tap me out.
Dock my pay. I don't care.
Come on. Big boy pants.
I'm with Beau on this one.
Bodies from mausoleums are ripe.
Ms. Kahn was embalmed
and hermetically sealed in that box.
The stench of formaldehyde is still so strong.
It's not just coming from her body.
Take a look at Sasha's hairline.
See?
FINADO: It almost looks like it kept growing
See?
FINADO: It almost looks like it kept growing
after she died. I didn't think that was a thing.
JACK: It's not. Her scalp dried out and shrank after she died.
Which is how we can see exactly where her processed hair ends.
It makes sense.
She died in the middle of a keratin treatment.
I use Pert Plus. You're gonna have to translate.
We're looking at two forms of formaldehyde here.
JACK: One in her body for the embalmment,
the other one applied to her hair
for the chemical straightening.
How do you know this stuff?
My sister has curly hair.
And I pay attention.
The assistant M.E. at the time
ruled it an accident.
She said it was an overexposure to the chemicals used.
But her sister woke up convinced that it was murder,
so, uh...
he didn't happen to mention how, exactly?
I'll take a run at it,
but I am not optimistic.
Sasha was fully embalmed.
Her arteries and organs were drained,
then plumped back up full of formaldehyde,
glutaraldehyde, methanol, ethanol, phenol and water.
There's not much of the original Sasha Khan left to examine.
If you want answers, you're probably
gonna have to go back to the crime scene.
It's nearly four years old.
Geriatric crime scene.
Sounds like a good time to get back up the horse, huh?
Lovely invitation, boss.
I told you: I'm a lab rat.

I mean, it's a better story, right?
Sure.
I mean, it's a better story, right?
Sure.
But it might not be intentional.
For either of them.
Yep.
I'll be in my office if you need anything.
Oh, hey, Max?
Yeah.
Oh, hey, Max?
Yeah.
Uh, do you have 200 or 300 rubber bands I can borrow?
Is that a yes?
Oh.
Oh, Linds.
This is Catherine.
Hey, it's Chavez.
So, Ken Taylor agreed to come in for questioning.
I thought you might want to join.
I'm on my way.
How exactly is my hair, or lack of it, relevant here?
We found a hair in the salon--
A hair in the hair salon?
Nice work, Detective.
In the ventilation system
next to a wire that had been cut.
Which is how the killer knew
that Sasha and Mimi would die from the fumes.
That... That's why Sasha died?
Yes, we performed a chemical analysis
on the hair and found finasteride.
Have you ever used finasteride, Ken?
Yeah, I have. I did. In the past.
When I was starting to lose my hair in the '90s.
It didn't work well, obviously.
So, you gave up in your 20s?
Just accepted your fate from the Hair Gods?
Never picked up finasteride again?
Ladies, believe me, I would kill for a thick mane of hair.
Would you now?
Bad choice of words.
But finasteride wasn't just a bust.
I'm allergic to it. Severely.
If you want my medical records,
you can see for yourself.
So? Is that it?
We're gonna need to see those records.
Fine. But I didn't kill my wife.
No matter what my sister-in-law says.
♪ ♪
Rarr.
(laughing) How is this?
FOLSOM: The size is right.
And the angle, too.
So that's got to be about where the monster was standing,
but the snout is all wrong.
Let's have a look.
It really doesn't seem human.
Well... whatever it is had to be moving
because the shadow isn't in all of the pictures.
Maybe a person behind a piece of equipment?
Hmm. Whatever it was, it's not there now.
If we find it, could be something the killer handled.
FOLSOM: Yeah, I mean...
Explore the salon. Knock yourself out.
I'll... I'll judge from here.
Or I could help.
I got it.
♪ ♪
Okay, well, that was a bust.
Yeah, whose terrible idea was that?
What are you, giving up?
No. Mimi said the monster
crouched down as if it was ready to spring at them.
But there's a wall here.
Maybe it got closer.
That's where Mimi lay,
with her head to the side.
Do you see there?
Yeah.
Hey.
Check that out.
It's almost like...
Say it.
Talons.
Okay, I don't believe this.
Everything in this case seems to be leading to some sort of
murderous, fantastical creature.
With a snout.
Fine. If you can't beat them, join them, right?
Let's see if this creature left any droppings.
(chuckles) Magical scat.
♪ ♪
Hey.
Is it possible that this fancy pants salon
was selling knock-off products?
FINADO: 100%.
Y-you remember when we couldn't figure out how the ingredients
in the shampoo and conditioner didn't match the ingredients
in the bottles? Never mind. Of course you do.
But it wasn't because someone added something
like they did with the-the Panamanian Perm,
noun, not a verb.
But the shampoo and conditioner,
it was because the original ingredients
were never there in the first place.
Now, after we tested each component
of what we did find in the bottles,
I can officially confirm:
that-that it's barely bargain bin drugstore quality.
I-I don't know if it would qualify as soap.
So, what is in there?
Oh, just a cocktail of your cheapest fragrances
and chemicals available.
Anionic surfactants, parabens,
polyethylene glycol,
all being sold at $38 a pop.
That is a crime in and of itself.
But is it motive for murder?
Always with the last word.
Just... always.
Always?
Always.
Can't really hear through the glass.
Can't hear you.
Wait a minute.
Here we go.
Bag three. Where's this from?
RAJAN: Here. Right next to the talon markings we found.
Do you know what this is?
A bit of plastic?
It's a very special hunk of plastic.
See the tessellation?
It wasn't a monster in that photograph.
It was a person wearing a gas mask.
The mouthpiece.
Tessellated plastic.
There is your snout.
And what kept the killer alive in a toxic environment.
So that's one small mystery solved.
Actually... I think this tiny piece of plastic
might just help us solve the whole case.
Hey. Somebody's having a good day, huh?
I sure am.
I can now definitely report:
there is not a violent, fantastical beast
roaming the streets of Las Vegas.
Yay, what a relief.
Mimi didn't see a monster the night her sister died.
She saw someone wearing a gas mask.
And she didn't see a monster crouch down,
she saw a masked poisoner fall down.
It's hard to see in those masks.
They probably tripped.
The killer's gas mask must've broken on impact,
that's why remnants of its charcoal filter
were scattered on the floor.
So the bits of charcoal you found on the floor,
weren't from a hair product.
Mm-mm.
I mean, there was a mystery, just not the mystery we thought.
What about the talon markings in the dust?
Plain old forearms and pinkies.
Yeah, that one's a little embarrassing.
Hey. I blame Folsom.
And?
What, that's not enough?
No.
Are you not satisfied?
No.
Who was wearing that damn gas mask?
RAJAN: Oh, we're going to find out.
♪ ♪
Hey. What do you got?
Nothing yet. You're about two minutes too early.
All right.
Nothing yet. You're about two minutes too early.
All right.
Hey.
What's up?
Oh, Lindsey's furious with me. Again.
It'll be fine.
Sorry about that.
Yeah, we both saw it coming.
Listen, when this case is over,
I'd like to take some time.
To really be there for Lindsey and Hannah.
If they'll have me. I don't know
if the timing is right.
Catherine.
You built this Lab.
You do whatever the hell you want.
Thank you, Max.
I'll tell you what.
What?
I think your killer had minty fresh breath.
Picking up something in that charcoal filter.
It-it's synthetic flavoring for spearmint.
There's traces of mint?
You know what else we'll find in that charcoal?
The killer's DNA.
Mint?
No, I'm... I'm good.
Well, not for long.
It was a tiny mint like this
that got you in trouble, Heather.
Excuse me?
ROBY: There were traces
of a synthetic spearmint
on the charcoal that we found at the salon.
WILLOWS: We knew that the charcoal came from the filter
in a gas mask the killer wore,
breathed through, so, we thought we'd run some tests.
Did you really think that your DNA would...
fade or something?
This is... I don't understand.
It seems like I should be asking for a lawyer.
ROBY: Oh, you'll get one.
But you don't need a lawyer
to hear that your hair looks good.
Yeah, her hair looks good, doesn't it?
It looks good.
That finasteride
works wonders.
ROBY: Right?
How did you... know?
We found this photo of you.
WILLOWS: And one of your hairs
in the vent, right next to the wire you cut.
ROBY: And we not only figured out how
you killed Sasha and put your best friend Mimi in a coma,
we figured out why.
You kept the books for the salon.
You stocked the supplies, you bought the products.
ROBY: You were buying knock-off shampoo and conditioner,
selling it as the real thing,
and pocketing the difference.
WILLOWS: How long were you at it before Sasha found out?
Was she gonna press charges?
Oh, it's really a moot point.
'cause she didn't give her a chance, 'cause you knew
that Mimi was giving Sasha
a keratin treatment that night.
You were an expert on the products
so you doctored the bottle.
WILLOWS: And snuck back in to kill the HVAC system.
And your bosses.
ROBY: But Mimi...
she is a fighter.
Yes, she is.
Doctors always said she might wake up someday.
WILLOWS: Right?
So you had to be thorough.
Just in case she ever did come out of it,
she wouldn't be able to ID you.
ROBY: You weren't just reading to her, were you?
You were telling her a story.
Ken killed your sister. Ken killed your sister.
WILLOWS: "Ken killed your sister."
Almost worked.
No. Mimi will defend me. Watch.
She will always believe it was Ken.
WILLOWS: Have a little faith in people, Heather.
They usually see the truth
when you show them what they need to see.
Hey.
Will.
I'm so sorry about your mom, honey.
