"Because now she was confused and afraid

and wondering if what she thought she'd heard

wasn't what Bertie had said at all."

And we will find out what happens next...

... same time tomorrow.

Mimi? Nurse!

Mimi?

Hi. Hi.

Call the attending. She's waking up.

Mimi.

Ready?

Ready!

Yeah, let's do it.

Whoa.

Oh, that's a little bruiser.

What-what's she in for?

Breaking and entering,

- her mother's room. - Ah.

My granddaughter doesn't want to stay

in her own bedroom, right?

Is that true?

Yeah, so Lindsey's a little tired.

I said I would take Hannah on my day off and...

- of course Max wanted to see me today. - Ready?

- Ah. - Yeah.

Favor. Can you just...

entertain her for, like, five minutes is all?

Mm-hmm.

Thank you. I'll be right back, okay?

Pinky's in the bag.

- Pinky. - How old are you?

Eight? 11?

Pineapple.

That's wild.

- I'm pineapple years old too. - Whoa.

So, this child psychiatrist, Dr. Auerbach,

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.

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.

Peekaboo!

Rarr!

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? - Look up there.

There's snacks and toys

and a change of clothes in the bag.

Okay?

Uh, just asking...

- for how long? - An hour.

Uh, two hours tops.

- Definitely less than three. - Okay.

Bye, Grandma.

Let's play.

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? - It almost looks like it kept growing

after she died. I didn't think that was a thing.

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.

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...

She 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.

We don't ride horses.

No.

Mimi Khan?

I'm Catherine Willows with CSI.

This is Detective Serena Chavez.

We're very sorry for your loss.

- Thank you. - And that it's taken us this long

to investigate what happened.

Well, you're here now. Thank you. Hi, I'm Heather.

- Hello. - Doctor says you were with Mimi

when she woke up. That's very lucky.

Odds were pretty good.

They always said there was a chance Mimi

would come out of it, so I...

She came and read to me. Every day.

Ah.

Could you hear her?

I-I don't think so.

But we were reading Beaches,

and I was thinking about Bette Midler when I woke up,

so something was getting through.

She was ventilated.

Her mouth is dry.

- You want a mint? - No, no.

No, that's okay.

Doctors said that your coma was caused

by severe systemic toxicity.

And Sasha went through the same thing,

except the chemicals were on her scalp.

It was too much.

What do you think happened that night?

Well, I...

I already told the police.

I-I've done keratin treatments in my salon for years.

This was different.

My sister and I were poisoned.

This was murder.

I'm not sure I understand what's being alleged.

All we have is a report from first responders.

A Good Samaritan was walking by your salon,

saw you and your sister on the floor and called 911.

Some... someone or-or...

something...

broke into the salon that night.

Before I blacked out, I saw a monster.

A monster?

Mm-hmm.

It-it was Sasha's husband Ken.

He did this.

He killed her. I-I know it.

It was so long ago.

Do you think that it's too late

to find out what really happened?

To find the truth? No.

It's never too late.

- No luck finding a sitter? - Please.

Grandmas are the reigning queens of babysitters.

It's just gonna be a couple hours before I get

Hannah back to Lindsey, right?

And it's not like Bryan didn't see

a bunch of minor crime scenes

- when he was a kid, and he's okay. - That's right.

This one's not even fresh, come on.

Wow.

No one's set foot in here for four years since Sasha died?

The sisters own the building.

It's just been sitting here empty while

Mimi's health was in limbo.

I mean, come on.

You got to love this.

Yeah, well,

lots of things get better with age.

I know it's counterintuitive,

but a crime scene is one of them,

if it's well-preserved.

DNA and prints just waiting to be collected.

It doesn't seem like there's been much

human interference since the paramedics

wheeled the sisters out of here.

Little chance of degradation of prints or DNA.

Oh, oh. Hannah, Hannah, Hannah.

- Oh. - Whoa, whoa, whoa, whoa.

Hey, you know what?

Why don't we both go outside and we'll look

for clues and we'll maybe get a snack?

Yeah?

How about you stay and I'll...

- Oh, yes, yes, yes, yes. - Hannah.

Hey, should we go outside?

Okay, I'll see you a little later.

- Let's go outside. - Wow. After you, my love.

- Yeah. - Oh, hi.

Oof, this dust.

It's everywhere.

Yep.

And it's not even my birthday.

- It's actually my birthday next week. - Yeah?

And, look, I got you a pre-dusted crime scene.

I feel like, uh, the desert air

and the passage of time ought to take the credit,

but thanks.

Mimi told us that she mopped up after the last customer,

so every footprint was made after the fact,

and the oils they left prevented dust collection.

Each set is gonna tell the story

of who was here in the salon after hours

the night that Sasha died.

The victim did say she saw the murderer

shortly before she lost consciousness.

A monster, actually.

She said she saw a monster.

Monster prints, then.

I'll keep a lookout.

We can rules these out.

That's paramedics.

Two down.

A zillion to go.

What you got?

A birthday present.

And it reeks of formaldehyde.

Ooh, thank you.

- Hey, Beau. - Hey.

Figured you could use a hand processing

the products from the salon.

Yeah, it's starting to stack up.

We barely even scraped the crime scene,

we've already got an exhumed body,

a bottle seal, bottles of shampoo and conditioner,

and a Panamanian Perm.

Oh, it must be like a Brazilian blowout.

Okay, that doesn't help me.

I-I don't even know if that's a noun or a verb.

It's a noun. "I just got a Panamanian Perm."

- Noun. - Noun.

Anyway,

it's either an embarrassment of riches

or a colossal waste of time.

Well, around here, Beau,

we choose to be optimists.

Looks like Mimi was right.

Someone did tamper with the keratin bottle.

Too much CH2O?

Yeah. Way too much. How'd you know that?

This puppy's drenched in formaldehyde.

Somebody must've spiked the treatment.

But even if the killer added extra formaldehyde

to the formaldehyde that was already in the bottle,

how'd he know it'd be enough to poison the two sisters?

Well, I know there's 0.7mg per 100g

of formaldehyde in Coca-Cola.

And I know that formaldehyde

played a pivotal part in Jonas Salk defeating polio,

but I don't know that.

Oh.

And... no formaldehyde

in the shampoo or conditioner.

No, but you know what is in those bottles?

Whole bunch of stuff that shouldn't be.

You're right.

Almost none of the ingredients match

what's supposed to be in those products.

How can that be?

The list of "Stuff I Don't Know" is getting longer.

Coming down here to my job.

Is this an intimidation tactic?

No, it's a fingerprint kit.

Dinking a Wiffle ball. That's your job?

I'm an accredited pickleball instructor.

Ooh. Accredited. Wow.

Have you gone to visit your sister-in-law

Mimi since she woke up?

We weren't close.

Well, I guess you never will be.

What with her accusing you of murder and all.

Are you really gonna believe someone

who just took a four-year nap?

They said it was an accident.

You know, she woke up convinced that you came

into the salon right before they fell ill.

How was your marriage?

Mimi said you and Sasha fought a lot.

Our son William was, uh, 19 then.

I thought he deserved to have some fun.

Sasha wanted him to... grow up.

She made him work at the salon.

They were oil and water, and... it spilled over.

Do you have an alibi for the night Sasha died?

I was out for a drive. Alone.

I remember being at exit 33

when I got the call from the hospital.

I almost drove off the road.

What else?

I'm in the middle of a lesson.

Just the fingerprints for now. We'll see you again later.

Scoot.

There you go.

Ready?

Really? Nothing?

I just made a coin vanish

and you're not even a little impressed?

What's that?

That...

could actually be useful.

It's a telephone.

It is a telephone.

Phone.

I think we've got a budding CSI here.

Runs in the family. Hey, Chris?

Could you take Hannah outside

- and show her how to bag the phone? - Yeah.

We got to protect the crime scene.

Ooh.

Doesn't that sound fun? Come on.

What do you have there?

I don't know.

Some kind of black powder.

I'll get Beau to test it.

So, do you think the killer's footprints

will lead us to some kind of proof?

Hope so. I've already identified 11 different sets

of footprints but several are the same size.

- Eleven? - Mm.

Didn't Mimi say that she mopped the floor at the end of the day?

It may not be as bad as it seems.

We know one set belongs to Sasha.

Mimi's is the most common size.

Yeah, and we already know about

the two that belong to the paramedics.

Yep. Those will be the patrol officer

that turned up at the scene.

That still leaves six.

Six sets of footprints that could belong to the killer.

We got our work cut out.

But Folsom and Chavez are helping,

getting foot sizes and gait analysis

for everyone here that night.

It was a Saturday, Saturdays were usually very busy,

so there were a lot of us working.

Oh!

I'm ticklish.

Sorry, we just need to get an accurate foot size.

That and gait analysis will tell us who was where.

Gives us a range of possible shoe prints,

tells us who went near the keratin treatment that was poisoned.

Oh. Okay.

I was restocking product at the front of the store.

We moved a lot of product. Great margins at the salon.

I kept the books.

Sasha and Mimi were really smart about how they ran the place.

Did anyone feel like they deserved

more than they were getting?

I don't know if you've ever worked in a salon before,

but there was a ton of drama.

Do you remember any drama involving Sasha and Mimi?

No. I loved Sasha and Mimi. Loved.

Until they fired my ass.

And...

when was that, Nick?

The day Sasha died. Which sounds bad, I know.

Yeah. It does.

What were you doing at the salon that night?

Closing up my station.

For good.

Can you pick up your pace?

'Cause if we can't gauge how long your stride is,

it's hard to tell which footprints were yours.

Anyway, Sasha and Mimi were sweet,

but they didn't know who to trust.

I mean, the fact that they kept that backstabbing...

"... talentless diva."

- He called me that? - Mm-hmm.

That's rich.

Like, look in the mirror, bro.

You know, Nicky,

would you say that a lot of the salon's drama

centered around you?

I like it better when she asks me the questions.

Uh...

did you have any issues with Sasha or Mimi?

Never.

Do you remember what you were doing

at the salon that night after closing?

Yeah. My hair.

There was kind of an incident earlier that day when...

I grabbed as much of Nicky's hair as I could

and I cut it off.

Not proud of it,

but it felt damn good.

Back up.

There was a Nick,

a Nicky, and a Nicole working at the salon at the same time?

Two words: scheduling nightmare.

Looking back at it,

I'm happy that I found out that Nicky

was sleeping with my boyfriend.

I kicked him out, got a dog,

living happily ever after.

But you weren't so zen back then.

Why'd you stay so late at the salon?

Honestly?

I wanted to watch that bitch try to fix

the hole in the back of her head.

Uh, can you please?

How'd you find out about the affair?

Sasha "accidentally" told me.

I know you're not supposed to shoot the messenger,

but it left a bad taste.

But the important thing is I've grown.

And the woman you see today would never

cut somebody's hair without their consent.

That's real progress.

100 days of being sober?

Yeah. I got my chip and everything.

Sure your mom would've been proud.

I think so.

But she's also the reason I drank in the first place.

- What'd you two fight about? - Nothing.

Everything.

That day, it was about being late to work.

I didn't know it was gonna be the last time I'd see her.

If I did, I wouldn't have been stomping around

the front desk like a little kid.

You know, I left without saying goodbye to my mom.

Or "I love you."

I'm kind of ashamed to say it, but...

I haven't seen Aunt Mimi since she woke up.

It's just all too much.

And then there was one,

but no one's story or shoe size matches this last set of prints.

Which leads...

nowhere. You got anything?

Just fungal bloom for days, on the walls,

in the plants.

Even fungus in this anti-fungal Barbicide.

How does fungus grow in an anti-fungal solution?

It was a sauna in here.

You know how it goes.

103 degrees is when the magic happens.

You know, you two are on to something.

It got hot in here.

I think I know why the killer was so sure

that souped-up keratin would be deadly.

The footsteps to nowhere end right here.

Hmm.

I don't think a rat did this.

Unless it could handle a knife.

System was serviced a week before

the sister died. It had to have been working then.

So the first casualty that night

was the ventilation system.

The killer made sure the keratin treatment

was more potent than ever.

And there was nowhere for the fumes to go but

into the sisters' lungs.

Pretty ingenious.

And pretty damn evil.

If this really is the killer's footprint,

he's no giant. This is like a...

men's size 9 running shoe.

Or a woman's size 10 and half.

Sasha's son William is too big.

Nicky and Nicole are too small.

That Leaves us with Sasha's husband Ken,

her best friend Heather,

and Nick, the employee they fired.

Only one of them was ID'd by the victim.

Ken for sure is suspect number one.

Did I hear right, his thing is pickleball?

I happen to love pickle ball.

It's not as fun as badminton, but it's easier

to find a game in this country.

I thought it was more like ping-pong.

Chris, can you at least

pretend to be useful?

Track the killer's footsteps.

Oh. Oh.

Hey, you know the, uh, black powder

- you found earlier? - Mm.

It's all along the killer's route.

I'm thinking maybe they left it.

- We, uh, should test it. - Yeah. Along with this.

- What? - Have a look for yourself.

Oh, wow.

It's the only fungal bloom in the vent.

I doubt much organic material was in here

when the system was up and running.

Maybe this sprouted from

something the killer left when they cut the air.

A girl can dream.

I mean...

you have to agree that is a beautiful thing.

It's a single follicle of hair in-in a dirty salon.

I mean, couldn't it belong to, you know, anyone?

It was in an industrial-grade ventilation system.

I think it would've been sucked out unless

the killer left it there when they disabled the system.

In that case, you're right.

It's so beautiful, I want a closer look.

Hey.

You know your mystery black powder?

Uh-huh.

- It's charcoal. - Oh.

That's not so much a mystery after all.

It's not?

No. It's probably all hype, but tons of shampoos

advertise that they contain charcoal.

Removes residue, adds volume, that sort of thing.

It is strange that we'd find tiny chunks though,

although some vegan products do add in raw ingredients

instead of synthesizing...

Aw.

- You're in over your head, aren't you? - Whoa. Look at this.

Hey, we've got finasteride.

Hair loss medication.

You take it to block the formation

of dihydrotestosterone, which leads to hair loss.

It looks like broken glass underneath the 'scope.

- That was on the hair you found? - Mm-hmm.

So our killer's going bald.

Ken has been balding ever since I've known him.

See?

Oh, no, I believe you, Mimi. It's just that

we didn't get any usable DNA on the hair.

And hair loss medication just isn't enough.

So... there's nothing you can do?

No, we're not giving up. We're still looking at Ken,

but we're also looking at everyone who...

You don't need to.

It was Ken.

It's not uncommon for coma patients to recover slowly.

For memories to reemerge in time.

I told you what I think happened that night.

But can you be more specific?

I...

I remember the treatment smelled...

different, more intense.

Yeah, that would make sense.

Someone doctored the treatment with added formaldehyde.

What else?

I remember...

the music, it-it got loud.

♪ I will survive ♪

N-not at first,

- but then it got loud. - ♪ Hey hey... ♪

That tracks, too.

When the ventilation system went off,

the music probably did sound louder.

Right.

That's all I can remember.

Except for just this...

sense that it was Ken.

He and Sasha had been fighting,

about William, about Ken spending too much money.

Mimi, did you see Ken that night?

It's complicated.

Kind of.

I know Ken was there.

I just... can't remember seeing his face.

I remember...

a-a haze of grey.

And a snout.

Like a monster.

I know it sounds crazy.

- A grey face and a snout. - Yeah.

And then the monster...

crouched down low, like it was gonna...

jump out at us.

Mimi, could you be describing a dream?

I'm telling you, it wasn't a dream.

- Hey. - So, I spoke with Mimi again

and, honestly, her testimony's gonna be worthless.

What are you looking for?

Nothing.

Hmm. Doesn't look like nothing.

Okay, I'm looking for a cord

to fit that phone that we found.

Don't we have a whole lab for things like that?

Yeah, but, you know, they get, you know.

Oh, Max.

You're an undercover mess.

Do not tell a soul.

Our secret.

So, Take Your Granddaughter to Work Day, hmm?

How'd Linds handle that?

Handle what?

The fact that you took her daughter to a crime scene.

It was a stale crime scene.

- As you know. - Mm-hmm.

And I didn't tell her. It's just easier that way.

So you think that a toddler

is not gonna tell her mama that her grandmama took her

to an old creepy hair salon

with no lights on and dust all over the place?

Uh, maybe not, I hope not.

That's my special stuff.

I'm just always skating on such thin ice with Lindsey.

Okay, I don't mean to overstep,

especially since I am the one to call you in

- on your day off... - Well, I'm the one who took the case.

... but what's it gonna take to make things right between you two?

I found it.

Suit up. Time for work.

This is Sasha's phone.

Last call made was 6:08 that night,

but... check these timestamps.

Wow.

Final moments here.

Wait. Go back.

What is that in the background, on the wall?

Is that a person?

It's got to be. Someone was in the salon

with them, or something.

"A monster."

And damned if it doesn't have a snout.

Maybe Mimi wasn't dreaming.

No. Maybe she was living a nightmare.

So, there's the source of Mimi's coma dream, huh?

Mm-hmm.

It looks like between this photo,

the finasteride that we found on the hair

that was in the vent,

and the killer's shoe size...

Everything that Mimi told me about that night,

about Ken, it's all adding up.

- Mm-hmm. - But still...

If I'm Ken's attorney,

I'm probably not too worried about casting doubt

on Mimi's recollection.

Well, sure, I mean, she was drugged, traumatized...

And most witnesses aren't popping out of a four-year coma.

Eyewitness testimony and-and physical evidence

don't always line up under the best of circumstances.

Half the time I reconstruct a crime scene,

- I find serious discrepancies. - Mm-hmm.

Just means that if Ken is really...

the monster, we just have to prove it.

I can go back to the salon, take a look at the space

with fresh eyes, and try to explain this shape here.

Forensic shadow puppets?

I'll let you know if we're up against a wolf or a bunny.

- So... - Hmm?

What do you think she means

when Mimi says she remembers Ken as a monster?

Okay. Even a healthy brain

is-is an imperfect storage for memory.

Our synapses, they-they fire and they rewire together.

And there are neuroscientists who say

that it is impossible for someone to have a memory

without altering it in some way.

What?

That, my friend, is Lindsey

and my problem in a nutshell.

I mean, what that girl remembers from her childhood

is so wildly different than what I experienced.

What you think you experienced.

Okay.

But I do think that Lindsey is...

a little prone to embellishment.

Maybe Mimi is, too.

A snout-nosed monster.

- 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.

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.

How is this?

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.

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.

Magical scat.

Hey.

Is it possible that this fancy pants salon

was selling knock-off products?

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. - Always.

Can't really hear through the glass.

Can't hear you.

Wait a minute.

Here we go.

Bag three. Where's this from?

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?

Oh, we're going to find out.

Hey. What do you got?

- Nothing yet. You're about two minutes too early. - All right.

- Hey. - 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?

There were traces of a synthetic spearmint

on the charcoal that we found at the salon.

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.

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.

- Right? - How did you... know?

We found this photo of you.

And one of your hairs

in the vent, right next to the wire you cut.

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.

You were buying knock-off shampoo and conditioner,

selling it as the real thing,

and pocketing the difference.

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.

And snuck back in to kill the HVAC system.

And your bosses.

But Mimi...

she is a fighter.

Yes, she is.

Doctors always said she might wake up someday.

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.

You weren't just reading to her, were you?

You were telling her a story.

Ken killed your sister. Ken killed your sister.

"Ken killed your sister."

Almost worked.

No. Mimi will defend me. Watch.

She will always believe it was Ken.

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.
