[thuds]

AUGUST 24TH (SATURDAY) 21:17

[SAKURAI]

According to our forensics lab,

there was a luminol reaction

on the skeleton's teeth.

The wound on the victim's leg

was also a match.

However improbable,

it's safe to conclude

that the T-Rex skull

was the tool used

to cause the dismemberment.

See, I told you

I was the Lizard King.

[YU] Can you not point

your spoon at me?

Now that we've confirmed

what caused the injury,

can you explain how you

came to your conclusion?

From the phenomenon itself

and my own observations.



[TAKAO] Based on the bite mark,

an incredibly large creature

must have been responsible

for the injury.

However, there aren't

many animals alive today

that would

fit that description.

We're too far away

from the ocean,

so it couldn't have been

a shark or other sea creature.

Basically, he had

to have been attacked on land

by some behemoth

that went extinct long ago.

Sounds crazy, right?

But then, I noticed

this museum was located nearby

and made the connection.

What a truly

brilliant deduction,

Dr. Ameku, as expected.

No, I don't see

how it makes any sense.

Are you saying the skeleton

moved on its own

-and bit off the victim's leg?

-I wish!

Now that would

be really exciting!

[groans]

If you don't mind, let's put

a pin in that for now.

Could you tell us why exactly

your patient's blood was blue--

[TAKAO]

Hold it.

I handed over info,

so now it's your time to share.

Ah, yes, I do apologize.

How could I forget?

'Cause you're a sneaky tanuki,

that's why.

[TAKAO] First, tell me more

about that skeleton.

Specifically, whether it was

fully built on Friday or not.

[SAKURAI] It was just about

to be fully assembled,

but they had to pause because

of the rain in the afternoon.

[rain splattering]

By the evening, though,

they had finished it.

[TAKAO]

I see.

Next, tell me about the victim.

Have you ID'd him yet?

[SAKURAI]

Yes, Kousuke Kumade, 23.

He served time

in prison for as*ault.

[scoffs]

[SAKURAI] When he got out,

he was seen entering

the HQ of a known g*ng.

So, a hoodlum, in other words.

[TAKAO]

How was the body found?

[SAKURAI]

Jiro Manabe discovered it.

He's the construction

site supervisor,

a man in his 50s.

Work halted due to the rain,

but he got worried

and went to inspect the site.

[Manabe gasps]

[SAKURAI]

And there was Kumade.

So, I imagine this Manabe

called emergency services?

[SAKURAI]

Actually, no.

The doctor at a nearby clinic

was the one who made the call.

Sorry?

[SAKURAI] The privately owned

Hachisuka Clinic was nearby.

Manabe rushed straight there.

The director, Dr. Hachisuka,

is considered

a skilled physician,

so Manabe brought him

to examine Kumade.

Why would he do that?

I mean, the victim

had a severed leg.

[YU] There wasn't anything

that could've been

done for him there?

[SAKURAI] That's what

Dr. Hachisuka thought as well.

So, he immediately called

emergency services

and began doing

chest compressions.

[sighs]



Um?

[YU]

What's wrong?

[grunts]

[YU]

Dr. Takao?

[grunts]

What in the

-Ow!

-[whimpering]

You could've asked me to move!

Wait, where are you

rushing off to?

Duh, Hachisuka Clinic,

where else?

HACHISUKA CLINIC

GASTROENTEROLOGY SURGERY

CLOSED: TUESDAYS AND FRIDAYS

[YU]

I figured.

Dr. Takao

you realize

it's almost 10:00 at night?

Let's come back tomorrow.

[footfall]

Uh, hello?

Um, that's not the way home.

[footfall]



[YU] For the record,

I think this is a bad idea.

[Yu sighs]

[door bell ringing]

Stop being a nuisance!

You're acting like you get

a prize or something

if you can ring it

enough times!

What do you think you're doing?

That's what I asked you!

What is going on?

Yellow tang, blue tang,

bluestreak cleaner wrasse,

carpenter's flasher wrasse.

Huh?

You know your tropical fish?

[TAKAO] You must be

the director, Hachisuka.

I am, yes.

But wait,

who in the world are you?

The Director of Investigative

Pathology at Tenikai General,

Takao Ameku.

Tenikai?

[NARUSE] You two need

to get out of here, now.

Oh, good evening, officers.

[SAKURAI]

I'm very sorry.

We're consulting with her.

You know, about the deceased

man with the missing leg

that was discovered

behind the museum.

I see.

[TAKAO] I was curious

why you didn't treat that man

at your private clinic.

You do have a surgery room.

Because there was

nothing I could do.

[HACHISUKA]

His leg was severed,

and his heart

had already stopped.

We were closed that day, and

there were no nurses on site.

Nothing could have

been done to save him.

Your hospital should know that.

[chuckles]

That's explains that.

[TAKAO]

Let's go, Kotori.

Huh?

So, we're done here?

[TAKAO]

Yeah.

-Oh, and, Sakurai?

-[SAKURAI] Huh?

Have your crime lab take

a look around the museum

first thing tomorrow morning.

[SAKURAI]

The museum?

-[SAKURAI] For clues?

-That's right.

It won't be long now

before the case gets solved.

I'm 100% convinced the culprit

left behind

vital evidence there.

[chuckles]

[Sakurai sighs]

[SAKURAI] Um, Dr. Ameku,

where are you taking us?

[NARUSE] You couldn't have

chosen a more difficult path.

Explain yourself already.

Why should I explain

myself to those

who are so stingy

with information?

-[SAKURAI] Hm?

-And what does that mean?

Behind this case,

there's a much larger one

that you're keeping hidden.

I'm not sure I follow.

Kotori, did you

happen to notice

all the suspicious men

around the crime scene earlier?

What men?

Oh!

[YU] The ones that looked

like they were yakuza?

[TAKAO]

Yeah.

Do you remember

what you said last night?

I'm too busy for this.

The Fourth Precinct's

been making

a real fool of itself lately.

-Well?

-[gasps]

The Fourth Precinct,

called the Organized

Crime Department now.

So, it turns out

they were actually police?

But why were they at the scene?

Try casting your mind back.

There was another

incident here yesterday.

Let me think.

[sighs]

Involving Organized Crime?



Ah!

sh**ting IN NERIMA WARD

[YU]

The Nerima sh**ting!

[fingers snapping]

Good work, my pupil.

A dangerous incident

that could've involved

innocent civilians.

[TAKAO]

And the sh**ter was

Kumade, yes?

After the body

was ID'd last night,

they learned he was the one

they were looking for.

Just one problem.

The person he shot was

a member of the yakuza.

Am I correct?

-You've lost me again.

-[sighs]

The police are convinced

the yakuza are responsible

and took Kumade's life

out of revenge.

That's why HQ set up

the investigation so fast.

If this case

isn't resolved quickly,

it may lead to an all-out w*r

between two rival gangs.

[SAKURAI]

What can I say, Dr. Ameku?

You do not disappoint.

Again, absolutely right.

[running footsteps]

[g*nshots]

[TAKAO] Did the yakuza member

shot by Kumade die?

-Get back here!

-[SAKURAI] No.

[SAKURAI] He's seriously

wounded, but still alive.

The guy's second-in-command

of a minor yakuza g*ng

that's currently at odds

with the g*ng Kumade's in.

Kumade fled after

being shot at himself.

The wound must have

slowed him down,

and he ended up getting

caught by the g*ng,

tortured, and m*rder*d.

[SAKURAI] That's what

we believe right now.

You said he was being shot at.

[TAKAO] Meaning a b*llet

might have hit him

and left bloodstains.

There might have

been some, yes.

-[panting]

-[TAKAO] What color were they?

[SAKURAI]

Red.

You know, like normal blood.

[MALE YAKUZA MEMBER 2B]

Find him!

Red.

That's right, detective.

[TAKAO]

Just like normal blood.

[sighing]

[TAKAO]

Oh, that reminds me.

Weren't you planning

on taking a closer look

around the museum either way?

[Sakurai and Naruse gasping]

For instance, why was the lock

on the back door broken,

perhaps?

How'd you know--

[TAKAO] [scoffs]

As I thought.

So, you already know

how everything played out?

[TAKAO] While I have a theory,

I'm not certain enough

to say it aloud yet.

That's why I'm confirming

my suspicions.

Okay, but where

are you taking us?

[YU]

The museum?

[footfall]

DO NOT ENTER

[door knob clanking]

[switch clicks]

[footfall]

[TAKAO]

And there it is.

There's what?

Wait, is that

what I think it is?

[TAKAO]

Yup.

Blood from our victim.

-What?

-Now hold up just a second!

[SAKURAI] Are you telling us

Kumade was dragged

all the way here?

For what reason?

[TAKAO] That, my detective,

is the biggest clue

to solving this mystery.

Good news.

[TAKAO]

If we follow the blood,

it should lead us

to the answer.

EQUIPMENT STORAGE

[door creaking open]

-What?

-My word.

Is that all blood?

This must have been

where Kumade was m*rder*d!



[chuckles]

[NARUSE]

Ah?

[YU]

Dr. Takao?



[door opens]

What'd you find?

Come on.

[gasps]



[MALE PARAMEDIC 1A] On arrival,

patient found unresponsive

with complete amputation

to his left lower leg.

[SAKURAI] He was seen entering

the HQ of a known g*ng.

[TAKAO] Why was the lock

on the back door broken?



[TAKAO]

That was pretty interesting.

-Huh?

-Huh?

[TAKAO]

First off, let's ask ourselves

why his blood was blue.

Also, how did his leg come

to be bitten off

by the Tyrannosaurus Rex?



For this mystery, allow me

to present my diagnosis.

AMEKU M.D.: DOCTOR DETECTIVE

[Hachisuka panting]

[door creaking open]

[HACHISUKA]

Huh?

[footfall]

[doorknob jiggles]

[sighs]

[groaning]

[sighing]

[gasps]

Well, good evening, Doc.

What a surprise running

into you at this hour.

-[gasps]

-I can't believe

he really came back here.

[SAKURAI]

Now, if you'd be so kind,

would you explain

all of this to us, Dr. Ameku?

-My pleasure.

-[Hachisuka gasps]

Before we declare

this case closed,

we need to carefully consider

every event that transpired

and how they connect.

[TAKAO]

The body with the blue blood.

The leg bitten off

by a Tyrannosaurus Rex.

The Nerima sh**ting.

The blue stain

in the storage room.

Once you put

the pieces together,

you get a sense

of the bigger picture.

Don't you think,

Director Hachisuka?

[whimpering]

[TAKAO] First and foremost,

we should focus

on the victim's blood,

and why it was that color.

The phenomenon itself

isn't that strange.

-Kotori?

-[YU] Yes?

If a patient's blood is blue,

what's the first condition

that springs to mind?

Hmm.

Well, let me think.

A disease like that

would most likely be

[gasps]

Methemoglobinemia.

Very good.

Could you explain

what that is to a layman?

[YU] It's a disorder

where the hemoglobin

in red blood cells gets

oxidized and turns blue,

hindering the normal

transport of oxygen.

Symptoms are dyspnea

and also impaired

consciousness.

It can lead to death

in extreme cases.

You're saying Kumade had

gotten this disorder somehow?

[TAKAO] To be precise,

in the short time between

when Kumade got shot

and when he died,

something else happened.

That something caused

the disorder to develop.

[NARUSE]

"Something" as in what?

[TAKAO] After executing

the rival g*ng's number two,

he was hit

by return fire and fled.

There's pretty much only

one thing to do after that.

Seek out a doctor?

[TAKAO]

Precisely.

Methemoglobinemia

usually shows up as a symptom

after being poisoned

by something.

But it can occasionally

be caused by drugs

like procaine and lidocaine.

And those are what now?

[YU]

Local anesthetics.

Kumade must have shown

signs of methemoglobinemia

after he received them

and died from lack of oxygen.

-[YU] Am I right?

-You are.

[SAKURAI] But Kumade

didn't just suddenly die

in a hospital.

This wouldn't even be a case

if he'd gone

to a proper hospital.

-[Hachisuka whimpering]

-[SAKURAI] What do you mean?

[TAKAO] Kumade didn't

have a normal injury.

He had gotten shot

during a gunfight.

[gasps]

The b*llet was still

in his body.

I get it.

He risked being found out

if he went

to an actual hospital.

His one choice was to seek help

from a corrupt

medical institution.

[SAKURAI]

A doctor for the underworld.

That's right,

a certain Hachisuka Clinic.

Turns out his clientele

includes organized crime.

[whimpering]

[TAKAO]

During the procedure,

a large amount

of local anesthesia

must have been used on Kumade.

As a result, he exhibited

methemoglobinemia,

and his condition

immediately became dire.

Fearing others would

discover his unsavory ties,

Hachisuka didn't take Kumade

to a fully equipped hospital.

Instead, he came here.

The one place

he could continue treatment.

[SAKURAI] That's the part

I'm still not clear on.

Why sneak a dying man

in here, of all places?

Because it had

the proper drugs.

[SAKURAI]

What drugs?

[TAKAO] Kotori,

would you kindly explain

how methemoglobinemia

is treated?

Huh?

Well, uh, you would need

oxygen therapy, right?

Come on, we both know

all that would do

is take care of the symptoms.

[TAKAO] In order

to properly treat him,

you'd need medicine

that turns methemoglobin

back into hemoglobin.

-[YU] Which is? Gimme a sec.

-[TAKAO] Good grief.

[TAKAO] You should

know this as a doctor

of internal medicine.

[whimpering]

[NARUSE] [gasps]

Is that Kumade's blood?

[TAKAO] Nope, this is what

would have saved him.

-[TAKAO] Methylene Blue.

-[NARUSE] What is it?

[TAKAO]

An aqueous solution

with a chemical

reducing effect.

It can be appropriately used

to treat methemoglobinemia

and administered orally

or intravenously.

[SAKURAI]

Just a second.

Why would the museum have

something like this on hand?

It's quite simple.

[TAKAO] Methylene blue

is used to k*ll pathogens

that cause white spot disease

and water mold on fish.

[SAKURAI]

Fish?

Turns out you knew

a lot of breeds, too.

[groaning]

Yellow tang, blue tang,

bluestreak cleaner wrasse,

carpenter's flasher wrasse.

Huh?

You know your tropical fish?

[TAKAO]

Based on the number of fish

the museum took care of,

you realized they must

have methylene blue.

GRAND AQUARIUM OF TROPICAL FISH

Kumade needed treatment

as soon as possible.

EQUIPMENT STORAGE

That's why you had to drag him

to the storage room.



And the large blue stain

we found on the floor inside.

[TAKAO]

This man tried to treat Kumade

by making him drink

methylene blue.

-[TAKAO] One problem.

-[gasps]

[TAKAO] He was already

dead by then, wasn't he?

[groans]

-[TAKAO] You panicked

and accidentally -Hey!

-knocked over the container.

-[HACHISUKA] Hey!

[TAKAO]

That's the reason we found it

in the storage room.

[SAKURAI] But, can we

get back to how his leg got

bitten off by the T-Rex?

You have to put yourself

in this guy's shoes.

If the body had been left

the way it was,

it would've been obvious

he had received medical help.

[SAKURAI]

That's true.

He severed the leg.

[TAKAO] After all, the b*llet

wound would have been evidence.

[YU] So that was the location

of the g*nsh*t wound.

Removing a human leg

isn't the easiest thing

in the world,

even for a doctor.

How very astute!

[TAKAO] And of course,

he couldn't use proper tools

to do it, either.

He wanted to make it impossible

for someone to tell

he had tried treating the leg.

He could only sever

the limb forcefully

with some kind

of heavy bladed object.

That's when he chanced upon it.



A head lined

with enormous fangs.

The perfect

instrument for the job.

The ideal sharpened tool,

68 million years

in the making.

[Hachisuka grunts]

[TAKAO] Afterward,

he carried the corpse

through the forest

behind the museum

and dumped it at the empty

construction site.

[sighs]

[TAKAO]

Ohyou didn't expect

that someone would find

the body right away, did you?

But, wait

Using the coincidence

to your advantage

you gave chest compressions

to Kumade,

who was already dead by then.

Then called emergency services.

That is smart.

They wouldn't be declared dead

if a doctor was the one

administering compressions.

[SAKURAI] By pretending to do

life-saving measures,

he delayed police involvement.

[TAKAO] And the rain

took care of the evidence

during the wait.

So, there you

have it, case closed.

The truth has been revealed.

I will say, that part about

using the T-Rex skull

and giving chest compressions?

[chuckles]

It was pretty ingenious stuff.

He would've pulled off

the perfect crime.

[whimpering]

Too bad for him,

he didn't count on one thing.

The hospital the victim was

taken to had its own genius.

[growls]

Now then, do you wish

to clarify anything?

Youyou don't

have any proof!

Hey, come on now.

Did you already forget

what I said

when I was at your clinic?

Oh, and, Sakurai?

Have your crime lab

take a look around the museum

first thing tomorrow morning.

[SAKURAI] The museum?

For clues?

Surely not.

Oh, I surely did.

[TAKAO] You panicked

and came back here.

For the methylene blue.

After all, your fingerprints

are all over the bottle.

Not a sophisticated trap,

but you fell for it.

[HACHISUKA] I So what if

my fingerprints are on it?

You can't prove

I cut off that guy's leg

and abandoned the body.

That's not enough to arrest me!

[TAKAO]

Ah, you really don't get it.

[gasps]

You think you're getting

arrested for damaging

and abandoning a cadaver?

[HACHISUKA]

Huh?

[TAKAO] You're going to be

arrested for breaking

and entering into the museum

with the intent to steal.

[Hachisuka gasps]

[TAKAO] Of course,

your clinic will be searched

after your arrest.

Who knows?

We might even end up recovering

some evidence there, too,

including Kumade's

fingerprints and blood.

Hey, we might even find

a leg in need of a body.

[gasps]

[sighing]

My diagnosis is complete.

Come along quietly.

[SAKURAI] Thank you for all

your assistance, Dr. Ameku.

[TAKAO]

The rest is up to you guys.

Kotori, let's go home

and have our study session!

[YU] At this hour?

It's already past midnight.

-[HACHISUKA] It's your fault.

-Hm?

[TAKAO]

Oh, I know!

We should totally find a way

to celebrate solving the case!

-What? -You just had

to go and interfere!

[gasps]

[growls]

I'll k*ll you,

ya meddling brat!

Get out of my way!

[growls]

[gasps]



[grunts]

[choking]



[thuds]

[sighs]

Who you callin' brat?

How dare you

insult a professional!

-You're the brat!

-[YU] Stop, Dr. Takao!

-[TAKAO] Let me go, Kotori!

-[YU] I think he's had enough.

[TAKAO]

The law's on my side!

This is self-defense!

[TAKAO] That karate of yours

comes in pretty handy.

TENIKAI GENERAL HOSPITAL

[YU] In mean,

after training for six years,

I should hope so.

[TAKAO] You were so fearless,

putting yourself

between your superior

and a

-[TAKAO] Ahh.

-Something wrong?

Ah?

Oh, Mazuru!

-Welcome back home.

-[TAKAO] Sis?

Isn't it kind of late to be

sneaking into people's houses?

[MAZURU] I was worried when

you weren't home, so I waited.

You didn't answer

your phone, either.

What were you doing

out so late at night?

Well, uh

We were helping

with a criminal case.

-[MAZURU] Dr. Takanashi.

-Yes, Ma'am!

My little sister's

caused you trouble again.

Thanks for all you've done.

Sure.

-As for you.

-[gasps]

[MAZURU]

You broke your promises.

You've been ignoring my calls.

And eating too many sweets.

And said you'd only drink

in moderation.

Well, like I said,

we were celebrating

solving the case.

-That's enough.

-You see--

Excuse me.

May I borrow her

a moment, Dr. Takanashi?

[YU]

Sure! Of course!

Oh, Kotori?

-[TAKAO] You little traitor!

-[MAZURU] Come with me.

I'll never forgive you!

[Takao grunting]

[Takao screams]

[chuckles]

[YU] Guess I'll get some

studying in while I wait.

[train alarm blaring]

[train horn blowing]
