All language subtitles for NINE.PUZZLES.E05

Yanghee Seo definitely killed Chimok Kang.

So why did I get a puzzle piece?

The puzzle murders
had nothing to do with Chimok.

Yanghee was the one who killed Chimok.

I'm sure Yanghee killed Chimok.

So it couldn't have been him.

What's happening?

What's going on?

Nine Puzzles

Why did you come to work so early?

Ew, I smell booze.

Were you up late drinking last night?

I'm always here early.

How about you?

Looking at these red lines,

they know exactly
how the body was chopped up.

I think whoever sent these puzzle pieces
to me is probably the killer.

That info was classified, right?

What are you talking about?

This case was all over the news.
Would've been pretty simple to find out.

You're wrong.

These are the exact parts mentioned
in the autopsy report.

That kind of info doesn't make the news.

That's weird.

It looks like
they could've drawn over an older drawing.

I noticed that too.

And what that tells me…

is that Chimok Kang was
the real murderer's main target all along.

But why didn't they kill him
with their own hands?

You think they let him go?

Or maybe they enjoyed watching the guy?

Slow down a bit and let me think, okay?

One thing's for sure now though.

-What's that?
-That each one of these puzzle pieces

portrays one of the victims
of these serial killings.

The gun, the whisper,

and the armband.

You got a point though.

Why didn't they kill them in person?

Could it…

have to do with their motivation?

Good to see ya. How've you been doing?

It's good to see you too.

Honestly, I was getting
pretty bored in here.

What's that then?

I've never seen anything like that.

It does show the same exact spots
that I cut though.

Wait a minute.

Are you trying to tell me
that I wasn't the only one

who was out to murder my husband?

That's right.
Could you tell me if there was ever a time

that you felt as though
you were being watched or followed?

They seem to have known
that you were out to kill Mr. Kang.

They've been watching.

Whoa…

I had no idea that I had an audience.

At the reservoir.

I had a feeling
that I wasn't alone up there.

But who was it?

One thing I'm damn good at
is noticing those tiny details.

Now how did you find that little suitcase?

I was pretty sure
no one would find it out there.

That wasn't the hard part.

There were some tread marks
at the entrance.

That's weird.

The two of us carried it there.

Yeah, I don't know man.
The police captain told me to wait.

-How long do you think this'll take?
-I dunno, could be a while.

-Hey, sir.
-Oh, hey, sir.

- What's the story?
- Hey.

Well, looking at the redness
of the mucous membrane

and the vomit around the mouth,

I'm guessing
the primary cause of death was poisoning.

'Round what time did he die?

I'd say between one and three
this morning.

He was already dead when the call came in.

Got it.
See if we get anything.

The gun, the whisper, and the armband…

What the hell are they trying to tell me?

Oh?

How you doing?

Has forensics finished up yet?

Just about.

Good.
Have your sessions been helping?

Just so you know,
Dr. Lee's better than Doc Hwang.

What?

Huh? Sessions?

What does she mean? What sessions?

Uh, I dunno what she's on about.

Huh?

Hey there. You guys doing all right?

You don't look too pleased.

Look who it is.

Oh, you're happy to see me.

Why are you here? Aren't you busy?

Yeah, why?

This is a pretty standard case.

We don't need a profiler.

Let's just say I'm here
to satisfy my curiosity.

Do you mind if I look around?

Is that allowed?

Where are those three
that drank with the victim?

Yeah, our three guys.

The first one, who called the police,
is at the station now,

being interviewed by San.

And Youngha's gone to meet
with the other two.

We've given all three a tox screen,

though they haven't shown
any symptoms yet.

I'm gonna check the camera footage.

Yeah, get the CCTV footage.

Curry Kim.

What's taking so long?

What do you mean?

Are you still not finished profiling me?

Am I really that hard to read?

Let's talk later, okay?

There was only one entrance.

And the CCTV system
had a clear view of it.

The perfect sealed room.

And yet, a killer…

was able to poison someone.

Mm… Scratch that.

There were no poison containers
found at the scene.

The killer wouldn't have poisoned
the drink in front of people…

which means
they spiked the drink in advance.

They made the victim drink
the poisoned soju by himself.

He didn't suspect anything
or put up a fight.

They couldn't have done that,
not without a really solid plan.

Detailed and careful planning,

cold and calculated execution,

and a high degree of self-control.

All of these traits are a match…

for the Puzzle Killer.

Hang on a minute.
Can you zoom in a little?

Are you able to fast-forward it?

Seems the only people in or out
were the three of them.

Let's go talk to them.

At first, I just thought he was sleeping.

When I woke up in the morning,
it was 8:00…

Uh, I mean, it was almost seven.

And, um, I shook him to wake him up.

We had to get to work.

But something wasn't right.

He wouldn't wake up,

so I reached out
and grabbed his hand, like this.

His hand was…

really cold.

So I was like, "What's going on?"

And took a closer look at his face.

That's when I noticed…

that he wasn't breathing, you know?

Then I called the cops, yeah.

Younghan returned to work yesterday,

so we all got together
for dinner and a drink.

Guess we started drinking around eight,
after we clocked out of work.

My wife didn't want me to stay out late.

I kept telling her that I was leaving,

and I got into a huge fight with her
on the phone.

Around 1:00 a.m.

Wanna know who bought drinks?

Yeah, I bought the makgeolli.

The soju as well.

I don't normally drink soju though.

I also bought some canned peaches,

kimchi, and some peanuts too.

Snacks, right?

Uh, then there was the instant noodles
all of us ate for dinner.

Jungchul brought those.

Um…

I don't, uh, remember exactly
what time it was.

But, um, when I got back
from the bathroom,

I saw that Younghan and Jungchul
were sleeping already.

Gabje wasn't around.

So, uh, since there was
no one left to drink with,

I… just went home.

And then, when I got to…

work in the morning…

they told me that Younghan…

was found dead.

So, like…

did someone poison him intentionally?

Their testimony does line up

with the CCTV footage
recorded at the scene.

So which one of 'em did it, hmm?

None of these guys
looked like they were lying.

Let's not forget that those guys worked
with Younghan Choi for more than a decade.

And yesterday was his first day back
after taking a year sabbatical.

Almost like they waited to kill him
till he came back.

How about his family?
You get ahold of 'em?

Uh, well…

His wife passed away five years ago.

And his son died last year,
so there was no one to contact.

So are you just giving up?

See if he's got a sibling
or some relatives.

-Get in touch with them.
-Yes, Captain.

Oh, come on.

Shouldn't the first people you call
when something bad happens be family?

That should be the way, right?

I'd call 911
if I found somebody unconscious.

Sure, I get that.

But he just found a body,
I betcha he called me first

because he wasn't thinking straight,
know what I mean?

Anyway, he called me on the phone

and kept telling me
that Younghan wouldn't wake up,

and that he didn't know what was wrong.

And then,
I told my husband to call the police,

and that's exactly when he called.

Look, my husband didn't do it.

Didn't do what?

All I'm saying is he doesn't have it
in him to harm someone else.

Aha, the cause of death
hasn't been released,

but you seem to know a lot.

I'm his wife, of course I know a lot.

What, did you think
he just kept me in the dark?

Oh, and I'd just like to add,
'cause you'll find out anyway.

It's true that my husband
borrowed money from Younghan,

but it's all been paid off now.

So I hope you don't get any wrong ideas.

Who told you about that, huh?

I betcha it was Gabje or Deokmun,
wasn't it?

Deokmun's a prick.

Yeah, it's true.

I borrowed a bunch of money
from Younghan, okay?

But I always paid him back every month.

I was down to, like, three million.
What d'ya think?

You think I killed someone over three mil?

Then why the hell would I've paid back
the seven million?

You think I'm an idiot, huh?

I really just wanna help you.

Look, obviously,
that asshole Deokmun is the one.

You said the soju was poisoned.
The soju, right?

Well, Deokmun was the one
who took it out of the fridge, 'kay?

And here's the kicker.

He didn't drink any!

And then, at some point,
that son of a bitch woke me up

just to say he was leaving.

I mean, he normally just leaves
when he gets too drunk.

Why the sudden change, huh?

Why, huh? Is it 'cause…

he needed a fucking alibi
or whatever the fuck you call that?

Oh, fuck this shit, I mean… I swear! 'Kay?

He was the fucking one
who put this whole goddamn night together!

Ah, shit, I'm so fucking pissed right now!

Do you know this guy?

Yeah, I do. That's Mr. Lee.

Yesterday, he bought some soju,

three bottles of makgeolli,
some pig trotters,

some kimchi, and a few other things.

How do you remember it so well?
Did you pick it all out yourself?

Hey, it was only yesterday.

That dude comes in here a lot.

He normally just buys makgeolli

without any snacks, but…

he bought snacks and soju yesterday.

So I thought to myself, uh…
"What's his deal?"

What time did he come by?

Gimme a sec. Lemme have a look.

He was here at 7:42 p.m.

Oh, he bought a bunch of other stuff.

Peanuts, peaches,

lip balm, and wet wipes.

Didn't Deokmun arrive at…

the break room at around 20:16 or so?

That's right.

It took him 34 minutes to get there?
It's a five-minute walk.

Captain, we have the cause of death.

Apparently, it was nicotine poisoning.

Nicotine?

Yeah, anything above a 3.7-milligram
blood-nicotine level is lethal,

and tox showed
his level was higher than 5.9.

And they found traces of nicotine
in the soju bottle.

As for Deokmun, Jungchul, and Gabje,

their tox screenings
all came back negative.

The hospital just told us.

That means… that Younghan was
the only one who consumed the nicotine.

Yeah, it sure looks that way.

Uh… Gabje Kim smokes though.
He smokes e-cigarettes.

Yeah.

His brother-in-law owns a vape shop,
doesn't he?

All right, let's just think about it
a second, 'kay?

Okay, let's just say, uh…

Let's just say I really did it.
I wanted to kill Younghan, 'kay?

Pretend you're me for a second, detective.
Would you use nicotine to do it?

Most killers gravitate towards tools
they're used to using.

I just didn't do it!

I was seriously just going to show up
to say hi and then leave.

Look, the only reason
that I ended up staying there late

was 'cause Younghan asked me to.

Hang on a minute.

You should talk to Jungchul.

Younghan lent him some money recently.

I bet he hasn't paid him back.

They were together until the end.

To sum things up,

we know that Gabje made a bulk order
of nicotine about a month ago.

And Jungchul was with the victim
till the very end

and had financial dealings with him.

Deokmun has a 34-minute gap in the day,

and he took the poisoned soju
out of the fridge,

yet chose not to drink
any of it that night.

Gabje suspects Jungchul of foul play,

and Jungchul suspects Deokmun. Is that it?

Deokmun did it.

Look…

I think we could all agree
that the soju is what killed the guy,

and Deokmun Lee was the only one
who had anything to do with it.

He purchased the soju,
he brought the soju,

he served it, and he didn't drink it.

- I'll have to go with Sukwang on this one.
- Right.

Besides, those 34 minutes really bug me.

We can't find anyone
who met with him or anything.

Hey.

Yeah, but…

…what was Deokmun's motive?

Huh?

I agree, he's a prime suspect,

and I agree
that the missing 34 minutes is suspicious,

but what was his motive?

Younghan Choi may have been an introvert,

but he took good care of his friends
and the people he knew.

He even gave them
New Year's presents every year.

We know Deokmun looked up to him
'cause they were from the same town.

The two of them didn't have any bad blood.

Did Lieutenant Yoon say anything,
motive-wise?

I'm curious 'cause she came by.

You punk!

Why would you even ask that?

All we gotta do to end this

is to find the evidence
and get the perp to confess.

You're a detective, not a… profiler.

I just don't see a motive.

When do we not see the motive?

When we don't have enough evidence
to work with?

Wrong, that's not the answer.

Since when did she need any evidence?

She solves the case at the crime scene.

Could there have been something off
with the crime scene?

Wrong, that's not the answer either.

There's no such thing
as an "off" crime scene

unless it's been tampered with.

You're right.

I guess this could be similar
to the Chimok Kang case.

A scene that's been tampered with.

Captain,

you're a genius.

You just figured that out?

Curry Kim, what are you doing here?

I figured you might show up.

Do you know why people kill other people?

Some people kill because a stranger
they just met a minute ago

won't lend them 1,000 won,

and some kill 'cause the laughter
of a stranger they hear

while out on a stroll
rubs them the wrong way.

Do you think
one of our three suspects is the killer?

Are you saying they're not?

Motive.

Oh, there might not have been one.

So… you're telling me
the killer had no motive

when they made the victim
drink poisoned soju?

The motive might not be clear,
but there had to have been one.

You're a smart cookie.

You've read some detective novels?

You ever read the Agatha Christie novel,
Crooked House?

No.

Well, in that story, there's a murder
in a sealed room just like this,

and every family member on the scene
has a strong motive to do the deed.

Can you guess who it was
who killed the grandpa?

I shouldn't tell you, it'll spoil it.

Out with it.

I won't read it anyway.

The 12-year-old granddaughter
was the killer.

Her motive had been obscured by her age.

Someone who was beyond suspicion
turned out…

to be the killer.

How cliché.

Nowadays, there are a lot of cases
where the killer is a kid.

I guess it's just an old book.

Then how about this one?

The Murders in the Rue Morgue.

The very first detective story,
published in 1841

and written by Edgar Allen Poe.

Who was the killer
in that sealed room mystery?

An orangutan.

I've thought this for a while.

I think you're losing it.

You're missing the point.

All I'm trying to tell you
is that homicide cases

can often be unpredictable like that.

Did you get another puzzle piece?

Come this way.

Where are you going?

Hey, what's with the…

Gabje Kim

There.

"Gabje Kim"

Now then…

Mr. Gabje…

why did you kill Mr. Choi?

Come on, what the hell are we doing here?

Why did you kill Younghan?

If I were Gabje, you mean?

I guess it's because…

So I got a promotion…

later than Younghan did. Shoot.

I mean, I joined the company
earlier than he did.

Do you think
Younghan rubbed that in his face?

I'd guess not,
knowing Younghan's personality.

Then again…

maybe, um, I may have had a slight
inferiority complex towards the guy.

Just like Hansaem Kim?

Mm-hmm.

Whoa, don't do that!

I don't have an inferiority complex.

Inferiority complex or not,

he's not someone
who would have acted on it.

We're talking about a dude
who's so indecisive

that he has to call his wife to ask
what to have for lunch.

Aside from that,
Younghan was the only person

who recommended Gabje for a promotion.

There was nothing for him to gain.

There's no motive here.

"Jungchul Yeo"

Now Jungchul… Hmm, let's see…

Money issues.

You've seen my transaction history,
I've only got 3 million in the bank!

I'm innocent, okay?

Hmm.

I just don't think
that's enough of a motive.

It's not like he didn't work
to pay the man back or anything.

The money isn't the issue here.

Maybe if there were emotions
attached to the cash.

Although, Younghan wasn't the kind of guy
that would've nagged him.

I guess he didn't even
charge interest, right?

That leaves us…

with the man your team considers
to be the prime suspect.

Deokmun Lee.

Anyone would assume
I'm the guy who did it.

I'm the only one
who didn't drink the soju.

I took the soju bottle containing nicotine
out of the fridge.

Also… my missing 34 minutes.

Want to know…

…what it was I was doing?

What the heck?

What are you doing?

Are you implying
he met his mistress or something?

That's wassup!

I went to visit my mistress,
who also works at the factory.

That's why I got the lip balm,

and also why I didn't wear
my wedding ring that day.

You following?

What are you, a PI?

How the heck do you know
he was having an affair?

Do you think
Younghan knew about their relationship?

He may have told him to stop seeing her,

and then Deokmun got angry
with him for saying that.

But then if we were to consider
how impulsive Deokmun Lee is,

we would certainly have seen
signs at the scene.

However… there weren't any.

So he didn't do it.

So did you get a puzzle piece or not?
Can you answer that?

Detailed and careful planning,
calculated execution,

and a lot of self-control.

All of these traits match
the puzzle murder suspect.

That checks out.

Uh-huh. So did you get one or not?

Hang on…

That soju bottle with the nicotine in it…

How long do you think
it had been sitting in the fridge?

I've no idea.

The security footage gets deleted
every week.

I'm just wondering what the chances are
that the bottle could've been, uh…

somehow put in the fridge in advance.

What if there was a trap being laid
for the three of them…

trying to get them to suspect each other?

We shouldn't be looking at these three.

The cause of death is elsewhere.

I think we should expand our search.

I think that Deokmun, Jungchul,
and Gabje are quite lucky

because Younghan died in their place.

Are you saying
that the wrong person might've died?

All I'm saying is
we shouldn't rule anything out.

The killer might've born a grudge
against all four men.

That could also be true.

Hey, did they pay you for yesterday?

Yeah, they paid enough.
Took my girl out to dinner.

The boss really paid you that much?

Besides the victim and the three suspects,

there's one other person
that's been in and out of the break room

over the past seven days.

The janitor, Mr. Yeom.

Look at this.

He went in five days ago.

Again, three days ago.

And even the day before.

I wonder what he's got
in the bucket on the cart.

Apparently, he hated that those guys
would party together in the break room.

It used to be dorm lodging
for the foreign workers,

but they were using it as a break room
because it was vacant.

Now Jungchul told me

that he ran into Mr. Yeom
on the morning of the incident,

and Mr. Yeom said…

"You seem fine."

I noticed
you went in and out of the break room.

'Course I did, it's my job.

Why's that weird?

I'm a janitor, that's what I do.

Uh, what was in that bucket on the cart?
Aside from your cleaning tools.

There was nothing in there
but cleaning tools.

A little while back,
you bought some nicotine.

So what?

I smoke a vape while I'm at work.

See?

Mr. Choi gave it to me.

Mr. Kim's brother-in-law.

He opened an e-cigarette store,
so Mr. Choi bought one of these.

But then, he told me he doesn't smoke.

And he gave it to me.

He told me I should try it.

Is it true you didn't like it
when people drank in the break room?

I still don't like it.

But you know…

it's just part of my job.

On the morning that Mr. Choi was killed,

you came across Mr. Yeo.

Why did you say, "You seem fine," to him?

I said that
'cause I rarely saw him that way.

Most days, he was badly hungover.

He looked really awful to me.

I don't know what those three men
told you about anything,

but it wasn't me.

Mr. Choi was a really good man.

I didn't kill him, I swear.

Say, uh…

anyone ever tell you guys about
what happened a year ago at the factory?

What's bothering you so much?

If I…

decided to kill you right now…

what's my motive?

Kill me?

Right now?

Kill me. Huh…

I guess that'd be…

curiosity?

You can see that?

I know what kind of person you are,
Ms. Yoon.

Well, why can't I see the motive?

It's hiding from me.

Leaving traces of one's crime
at a crime scene is inevitable.

Even if a killer tried
to clean up the scene,

we would be able to learn something.

So why…

What kind of person was the victim?

It seems to me that…

you've always… looked at your cases
from the side of the aggressor.

This time,
try looking from the other side.

Put yourself in the victim's shoes
and look the culprit in the eyes.

The culprit… had no motive to kill me.

So why'd I end up dead?

Was that person
even the culprit to begin with?

Maybe it's time to return to square one.

Details on victim

2022 January 18,
death of son Dongkyung Choi

That was it.

We should've focused on that
from the start.

Mr. Choi's son died a year ago.

Why didn't you tell me that?

Does that, um…

give you an idea?

For a single man in his fifties,
living all by himself,

this house is too clean to me.

It's so clean that it's weird.

Yeah, this place is
a whole other level of tidy.

Everything's been… arranged meticulously.

It seems like
he was getting ready to go on a trip.

That's a strong observation, Curry Kim.

You pick that up from one of your novels?

My curry friend's house
was just like this.

That friend also lived alone
without any family.

They tried committing suicide.

It was all an act, wasn't it?

I guess…

the victim did have a motive in the end.

You said Younghan's son
died a year ago, right?

Try asking those three men about it.

Ask them why Younghan Choi
might have wanted the three of them dead.

I called you all here
'cause I wanted to ask you something.

Was there anything that would've made
Mr. Choi want to kill the three of you?

You got nothing to say?

Fine.

Let me ask again.

How are the three of you linked

to the death
of Mr. Younghan Choi's only son?

Dongkyung died a year ago, right?

Mr. Yeom's already filled me in a little,
but I'd like to hear it from you.

What happened at the factory last winter?

- I look forward to working with you.
- Thanks.

Hey, all right.

I told him to relax till he gets
to college, but he won't listen.

Yeah, well…

I think it's cool
he wants to work to pay for college.

You know, he's gonna go far.

-Thanks for the drink.
-You're welcome.

I heard you nailed your entrance exam.

Wow.

Younghan, this kid must be
your pride and joy.

Hey, you owe us a drink.

All right.

-For real, you owe us a drink.
-Yeah, okay, fine!

Hurry!

Over here! Hurry!

Mr. Choi wasn't at the factory that day.

He was away on business.

There's an accident and Mr. Choi's son
was taken to the hospital.

But by the time the ambulance
could get him to the hospital,

it was too late.

The kid was dead.

They said that he got caught
in the conveyor belt.

But exactly what happened
and how it all went down,

I'm not entirely sure.

Those three guys?

They were there. They should know.

-You can handle this, right?
-Yeah, sure.

Uh… are you sure
I just use this broom to do it?

That's what we do.

Yeah, you just need to nudge it
with the broom

so it doesn't get stuck in the machine.

-And try not to break it.
-Okay, got it.

-Get to it then.
-Okay.

I'm coming, okay?

Yeah, you guys get started.

What's that?

Whoa, kimchi, pig trotters, and makgeolli?
Sounds great!

-Hey, get over here.
-All right.

- Come here!
- Let's do it!

It's still warm. Yeah, come on.

-Here.
-Ah…

Good work, you two.

-There. Cheers.
-Yeah.

All right.

Ah, that's good.

Oh, shit!

Dongkyung!

What the hell happened?

What happened?

- What do we do?
- Shut it down! Go!

Hurry up and pull!

It's stuck!
It won't come out!

Dongkyung!

Ah, Jesus, how did this happen?

Hey, man!

How could you leave
this kid unsupervised, huh?

Oh, God, I'm gonna call 911. Oh, Jesus…

Ah, shit.

-Wait, hold up.
-Come on!

We should call the boss first.

Why should we do that?

Remember the last time we had an accident?
Hassan, that Pakistani kid, you remember?

The boss told us
not to make any decisions at all.

He told us to report everything in first,
remember?

Oh. Oh, yeah, you're right.

-Call the boss right now.
-Okay, I'll call him.

Shit! What do we do?

Should we try to pull him out?
Huh? What d'ya think?

Whoa, don't touch him.
My God! That's dangerous.

The boss isn't picking up. What do we do?

Shit!

He's not answering.

Look, we didn't leave our stations,
all right?

-And we were working with the kid.
-Yeah, uh-huh.

We're all fucked otherwise.

-Okay.
-Yeah.

It was quick.

The kid got careless, okay?

-We did nothing wrong, 'kay?
-Right.

Did Mr. Choi ever blackmail you
regarding this?

Did he ask you for money?

No.

Younghan knew that it was an accident.

It wasn't just an accident!

You think Younghan didn't know that?

I've been wondering why he died
on the day he returned to his job.

Originally, I thought
that one of you three

had been waiting for that day.

When, actually, it was Younghan
who had been waiting.

What do you mean by that?

Younghan must have been
so angry with you three.

I bet he wanted you all dead.

If you guys hadn't left his son
alone unsupervised,

he wouldn't have had an accident.

If you had only called 911 first…

then maybe he wouldn't have downed
a glass of soju laced with nicotine.

Younghan…

Stop half-assing
everything you do, it's annoying.

Just step off, man.

Ugh…

Have a drink.

We're all out.

I told her I'd leave soon.

I need to take this.

Hey.

I told ya I'm coming home soon.

I'll go grab some more alcohol.

I could use the fresh air.

I think there's, uh,
some soju in the fridge.

Let's just drink that.

There is? Really?

Ah, sweet.

Here, you go ahead.

I just need to take a leak. Be right back.

He looked too clean
for someone who drank the night away.

Then I went to his house,
that's when I knew.

That's what confirmed it.
His house was the same way.

It was tidied up like he was never
coming back from where he was going.

I mean, how would any of that matter
once you're dead?

Why would anyone care, you know?

Younghan Choi's house…

was like a stage set for a play.

There wasn't even a family photo
hung up on the wall in there,

but there was a photo of the four of them
stuck on the mirror above the dresser

as if to draw the audience's attention
by shining a spotlight on that spot.

So stupid, isn't it?

Did he really think
that he could fool us with all that?

I mean…

he could have just killed them all.

Why did he kill himself instead?

Besides, if he wanted
to pin the murder on them so badly,

why not come up with a much better plan?

Right?

I just don't understand
the point of it all.

Ms. Ena.

Calm down.

I've never seen you
get so worked up before.

What is it
that's making you get this angry?

All of it!

Hmm…

Sometimes, when people

get stuck in a tough situation,

they may kill other people,
or they may do harm to themselves.

This man was the latter type.

He killed himself
because he couldn't kill someone else.

He could have taken
everyone else out with him though.

I don't understand
why he chose to only take himself out.

I'd say that he wanted
the three of them to…

suspect each other and go to jail.

I imagine he was hoping those three men
would be branded as killers.

And I'm guessing that he didn't want this
to be seen as vengeance.

As far as Younghan was concerned,
those men were murderers.

I hear you,
but I still can't wrap my head around it.

Mr. Choi was…
a man with quite a soft heart.

I mean, he probably
didn't have the courage

to watch those men meet their end.

Just like you.

I'm not soft.

You may put on a tough front,
but you've got a soft heart.

I absolutely do not.

All right then.
Let's just say that you don't.

You should go.
I have a dinner appointment to get to.

Am I playing Mr. Choi this time or what?

Sit down.

Who would've thought it'd be suicide?

I thought this kinda stuff only happens
in John Dickson Carr novels.

I heard when folks
are in a tough situation,

some of them kill other people,

and some folks choose to kill themselves.

What do you think I would do?

You've been watching me for a while now.

Are you still not totally convinced?

I've got a soft heart, you know?

Tell me now. Answer.

And you answered me correctly.

I'll show you now. Check it!

When did you get this piece?

Wait…

Chimok Kang was cut up like that.

How did they know that?

Maybe 'cause the killer is around us.

We should probably ask them
when we see them.

Why was it
that they let Yanghee take the kill?

The sender of the puzzle pieces
is definitely someone who kills others.

How do you suppose they got to this point?

What do you think
drove them over the edge?

Why are the people in the puzzle

shooting at little human-shaped dolls

or holding cotton candy
and smiling while whispering?

Why are they dancing
while wearing armbands?

Is it that…

the three of them weren't victims at all,

but culprits instead?

Like the case this time.

What?

What if Donghoon Yoon, Miyoung Lee,
and Chimok Kang…

committed a crime?

What if there's a case out there
where they're the culprits?

And what if there are even more culprits

to be revealed?

We've only got three pieces of the puzzle.

But we could end up with six

or maybe nine of them.

You never know…

we could get a lot more.
