Perfect Number Page #2

---

We analyzed it as the electric wire

often used in irons

Irons?

Estimated time of death?

We estimated it as November 9th

in between 4 P.M. and 11 P.M.

So the victim was walking alive

before 4 P.M. on the 9th

- Correct?

- Yes

"to be exact, he was alive till 736"

Based on what?

We found an abandoned

self-service rental bicycle on the scene

Self-service bicycles?

You can easily rent the public bicycles

by entering your resident registration number

It was rented from a kiosk in Sang-am district

It was rented with

Kim Cheol-min's resident number

Really?

So you have a suspect?

Considering the travel path and radius,

Kim Cheol-min's ex-wife,

Baek Hwa-sun is our prime suspect

The reason is?

Now, we need to find out

Thank you

Kim Cheol-min was found dead

He was brutally murdered

We had some trouble locating you

because your address was changed

According to the registration files,

he doesn't have any relatives

Do you know of any distant relatives?

I don't think he has any

I see

When did you meet him last?

I haven't seen him since I moved to Seoul

You haven't talked to him

during the recent months?

No

If you don't mind

what did you do on the 9th?

Pardon?

November 9th

I worked

And after you got off?

I took my niece to a movie

Guess it was a nice outing for a change

What's wrong with your hands?

What?

Your hands

I got hurt at work

When?

A few days ago

Hello

It's me from next door

The detectives were here this afternoon

I did as you told me

Ok. they're coming for Yoon-ah soon

Okay

What did you do to it?

How did they find out so quickly?

Did they find the body?

Just answer like a machine

only to the questions asked

They might be watching you from near

So even if we bump into each other,

act like usual neighbors

I'll warn Yoon-ah also

Did you tell them about the movie tickets?

No

You told me not to show them

until I was asked

Where did you put the tickets?

In my wallet

No, no

The movie flyer,

fold it in half and put the tickets inside

Not many people keep movie tickets

They might get suspicious

if you take them out from your wallet

Okay

I will

I'll always call you around this time

I was wondering

Yes?

If we really should do this

You have to trust me

Alright

The only family she has is her niece

She wanted to live out her sister's dreams

She was going to raise Yoon-ah for her sister

It is so sweet of her

I admire her

So she left town

Did Kim Cheol-min come here recently?

About a week ago

He went crazy here

trying to get Hwa-sun's whereabouts

So did you tell him where she was?

Are you insane?

What did he do this time?

Is he in trouble again?

He was murdered

Whoever did it, I am grateful

Hwa-sun will finally get some sleep at night

A real good sleep

Thank you

You said you saw a movie

with your niece on November 9th

Do you have the tickets by any chance?

Pardon?

The movie tickets

No, I don't

Oh

I have this though

Movie tickets

For November 9th

You saw this movie?

Detective Jo, what's with you?

Why are you keep insisting

Baek Hwa-sun is the killer?

She has a clear motive for murder

And her hands

It's due to strained ligaments

You saw the scar on victim's neck

When you choke someone to death

with a thin wire, you will get a sprain

That's a coincidence

There's no such thing

as a coincidence to a detective

Isn't it too perfect to find tickets

in between a flyer from the recycling bin?

What's wrong with perfect?

When are you going to become a real detective?

From now on,

it's about who cracks down first

Put out the cigarette

Let me warm up with it

No

It's cold

Turn off the engine, idiot

What's wrong with you, stupid?

Baek Hwa-sun

I think the cops are watching right now

Here

Isn't that the guy who went in first?

I think so

Pizza

Movies

It's all here

How did you end up

watching a movie with your aunt?

You're in middle school

Don't you have a lot of friends?

Guess you're very close to your aunt

She listens well too, right?

She'll do whatever her aunt tells

Anybody can use a credit card

I didn't use her card

She never gave it to me

Really?

So your aunt used it?

Yes

Thanks for the drink

What is wrong?

Wait

What are you doing?

Excuse me

You?

Cheers

I can't believe I ran into you here

this is so weird

It's good to see you

Hey, do you remember

the woman living next door to you

That case I told you earlier

She's the prime suspect

She has an alibi but

an alibi is there to be broken

It could be

Okay

Get in

Alright. See you later

Okay

Oh!

Doped out Pythagoras!

Right?

Right, right

It's been a while Doped-gores

It was good to see you

What happened?

What did you tell the detectives?

They're probably still here

Here. Act natural

as if taking something from me

Get inside

She was looking out the window

the whole time

As if she was waiting

Of course

The guy next door was talking to a cop

who thinks you're a suspect

Must be really nervous

I ran the credit card

"She bought the tickets exactly at 7:52"

So you believe Baek saw the movie

And on Kim Cheol-min's phone record

He ordered some Chinese on the 9th

and nothing else

He has never talked to Baek

Ok. think of it this way

The niece could've swiped the card

and says she didn't

Even if Baek went there herself,

there is plenty of time

But there's no proof that she didn't see the movie

Don't you dare look at me like that

So this is all about that

Goldbach's conjecture

Go where?

Goldbach, stupid

Like right now,

there is suspicion but no evidence

It will drive you nuts

Did you get anything from

your school friend?

Seok-go

Nothing interests him except for math

Math?

Have you ever seen a genius?

It's not divisible, it's a prime number

Yo, Kim Seok-go

Doped-gores

So you're a genius?

What are you going to

do with your genius brain?

Prove

Prove? Prove what?

Have you ever heard

of Goldbach's conjecture?

No way

So go on

Every even integer greater than 2

is the sum of two primes

True or false?

Nobody has solved it in 300 years

What do you think?

True

Then it's done

Do you must prove it?

If I don't prove it, I won't know the truth

I want to know the truth

The truth

You want to find the truth

By the way,

making a problem no one can solve

or solving that problem

Which is harder?

You prove that

How would I know?

Here. Lilac is the taste of love, true?

Prove that, say "ahh"

Good

If you want to prove it, chew it well

That is love, dude

Bitter, huh?

We went to high school together

It's an unexpected variable

but it's going as calculated

Don't worry

But you need to be more careful

about such actions

I'll trust you completely from now on

Did the cops question Yoon-ah?

Yes. She said they were waiting

outside the school

Can you get Yoon-ah on the phone?

Hold on

Hello

What did the cops ask you?

They showed me a picture

and asked if I've met him recently

I told them I haven't

They asked again about going to the movies
