Even if all the doors and windows...

...in the entire house are locked...

...you cannot say it's in a locked room state...

...if there's a person who has a duplicate key to the entrance.

When the body of a woman was discovered here...

...this house was in such a state.

But there is one reason why this house came to be in a locked room state.

So what was this reason?

It is said that the amount of information we receive each day...

...80% of them comes from our eyes.

However, you must not follow this incident with your eyes.

Smells. Sounds. Emotions.

The truth is hidden in what you cannot see.

...It was discovered that there were no prospects of settlement... ("Illegal Lending in excess of 2 billion yen [$25m]" ..."Enamel Co. Hides Large Loss")

Prosecutors are expediting the investigation of this company's actual financial status.

Hiding the business losses and embezzlement.

Corporate scandals do not go away at all...

What do you think about this, Serizawa-sensei?

Oh, if you don't mind me saying...

It's a mystery to me why a scandal like this continues...

In the companies where I conduct legal compliance...

...we've enhanced the monitoring network.

As a result, employee awareness have also changed...

Fraud and any kind of misconduct have all since died.

As a Sensei who specializes in corporate law...

...you are able to change the company's mentality.

...It's amazing. - Nah.

It's not me who made them change. It's the rules.

Although, the person who made the rules was me.

He said he adamantly doesn't want to go on television...

But once he is on... he's grandstands like a peacock.

Now I know why he's successful.

Next segment is an in-depth coverage of the news that everyone wants to know more of...

...It's time for 'News Catch-up!'

'An Accident or Murder? The Case of Locked Room Mystery...'

It's about the accidental death of...

..of popular manga artist, Nakata Fumie-san three days ago.

There's a chance that this could be a murder.

Regarding the details on this, we will interview Nakata-san's niece...

...the TV talent, Nakata Tomoka-san.

Nakata-san, thank you for coming.

Nakata-san, first off, why do you assume that there is a possibility of a murder?

When the body of my aunt was discovered...

...she was found inside a locked room.

So the police thought she was alone and drunk...

..when she bumped into something and a marble clock fell on her head.

It seems they have determined it as an unfortunate accident.

But there's one detail that I'm not convinced with.

What is it?

Yes. The estimated time of death...

...was around 6 pm to 8 pm on June 5.

The body was discovered on that same day at 10:11 pm.

I agree with her estimated time of death but...

At around 6 pm, I was talking to my aunt on the phone.

At that time, she told me...

That she was drinking with an assistant.

I see, that is inconsistent with the police's findings.

Just because it was in a locked room state, the police said...

...she was drunk and didn't know what she was saying...

If what she said was true...

There's a possibility that it's a locked room murder disguised as an accident...

- Yes. - I see. Was it an accident or murder?

Hmm...

Ah, by the way, Serizawa-sensei. Haven't you...

...solved locked room murders before?

Oh... well.

I read an article about you in a weekly magazine.

How many have you solved so far?

Uh, well.. it wasn't a big deal.

- Around 7. - 7 already?

- That many? - I thought you were a lawyer...

..who specializes in corporate law only but...

...you cover such a wide range of subjects.

Oh, uh, no. I may be an expert in corporate law...

But I'm not one of those greedy lawyers who only accept corporate legal work...

My policy is to accept...

...not by the size...

...but how much help the client needs.

That's my motto. Yes.

Then can I ask for your help?

- Pardon? - My aunt was not married.

Since I was small, she treated me like a daughter...

She loved me. And I loved her, too.

- No, wait. - As long as suspicion remains...

I cannot accept the death of my aunt.

So I ask you please.

Please investigate her death. Please!

Raise your head.

Please leave it to me.

The truth will be exposed and brought to light.

For the sake of justice.

Why do I have to handle these troublesome issues?

Don't complain to me.

You're the one who accepted this case.

Anyway, I want this resolved quickly as soon as possible. Call him.

- Him? - Of course him, who else?

So first of all...

...please tell me about the day that Nakata-san died?

My aunt's work studio is in her home...

Everyday she works with two assistants.

On that day, Tachibana Asami-san...

...started working at 9 am and then went home at around 5 pm.

The other one, Anzai Rikako-san came in at night to work...

It seems she came at around 10 pm...

...when she realized that she had forgotten her duplicate key.

She went round the back garden to try to call my aunt...

"Sensei! Sensei!"

Rikako-san called 119 at 10:11 pm.

5 minutes later, emergency services had arrived at 10:16.

At that time, all the doors and windows were locked.

- That means, it was a locked room. - Hold on a moment please.

Did you say there was a duplicate key?

Yes.

The assistants have duplicate keys to the studio.

So it is not a locked room status.

Actually...

It's true that the assistants were able to go in and out freely.

Even so, the house was in a complete locked room state.

"Be aware of burglars"

- This way please. - Alrighty. Let's go in.

Serizawa-san, you're enthusiastic today.

Of course. After what I said on TV...

I can't do a sloppy investigation--

Whoa! Ah! That startled me!

This is it.

Aunt Fumie got this dog a few months ago...

He will bark at anyone who passes by except my aunt.

There were frequent complaints that his barking is so noisy.

According to the testimonies of the neighbors...

From the time that Asami-san went home...

...until Rikako-san arrived...

It seemed not once did they hear the dog bark.

So during that time, nobody went...

..through that entrance? - Yes.

I see. So that's why it's a locked room.

If it was murder, how did the culprit go in and out?

That's the mystery behind this incident.

Please go on in.

The scene where the body was found had been preserved.

Please check it as much as you want.

- Please excuse us. - Excuse me.

- Yes? - About the emergency services who received the call...

...which one did they use to enter the house? - The front entrance.

At first, it seemed that they attempted to enter by breaking the window.

But the other assistant lives nearby...

She rushed over so they used her duplicate key to get inside.

- What is it? - Nothing.

This was my aunt's work studio.

"2 Cases of Beer"

(Hiring Requirements for an Assistant of Nakata Fumie-Sensei)

Oh.

Nakata-san had some pretty fine watches.

My aunt was an avid collector.

I also was a collector but a burglar got into my home recently.

That's an Infinity, a Long Island*... (*Franck Muller watches)

...ah, and also a Tonneau Curvex men's watch.* (*Franck Muller watches)

One of the watches had stopped.

That watch is my aunt's favorite...

It looks like it had stopped working on the night that she died.

Oh, you're right. It stopped at 10:15 on the 5th.

Uh, where did this Tonneau Curvex--

Could it be that my aunt's curse had made it stop working?

- No way. - Tomoka-san.

Where did Nakata-san pass away?

Over there.

This is just the police's assumption but...

...my aunt was drunk and appeared to have tripped over a document...

...and hit the shelf, then with the force...

- Oh, it's quite heavy. - Hey. Lemme try.

When I was talking with her on the phone...

She said that she was drinking with an assistant.

But...

There was only one glass...

So it appeared that she was drinking alone. (Ecos-Mart Receipt: 4 Beers, Mixed Nuts, Surume, Roasted Pistachio)

Drinking alone in a locked room.

Even the police will rule it out as an accident.

On the other hand, if this was a murder...

...the culprit could have made it look like this...

...after killing Nakata-sensei.

- I didn't do it. - Asami-san.

I respected Sensei...

She recognized my talent more than anyone.

There's absolutely no way I would kill Sensei.

I only came here to tell Attorney-sensei that.

I didn't want to be bothered later.

Go away please!

Hey... Ah!

Wait. What're you doing?

Please don't use such a thing!

I'm sorry. It's just...

- Oh. - What is that?

Oh, this is a K9 Canceller.

It uses ultrasonic sound waves that only dogs can hear...

It's an imported gadget used to repel dogs. I'm no good with dogs.

Why are you here, Rikako-san?

Tomoka-chan told me that Attorney-sensei is coming, so...

Oh. Nice to meet you.

I'm Anzai Rikako, Nakata's senior assistant.

I believed and followed Sensei for ten years.

Serizawa-sensei, please. For the late Nakata-sensei.

And also for Tomoka-chan's sake, please help us find out the truth.

I'll try whatever possible.

Is that what you really want?

- Oh. - I'm done.

I just need to check one more thing.

Until the body of Nakata-san was discovered...

...are you positive that not even once...

...did you hear the dog bark? - I'm positive.

I was ready to make a complaint if he barks at night again...

...so I was waiting. Then when he did bark...

..it was for the incident... when the body was discovered.

Is that so. Thank you very much.

Wait a second. You're from the security company, right?

Can you put some security cameras at my house?

This area is prone to burglary, it's dangerous.

I understand. I'll contact the person in charge of this area immediately.

Both of you listen.

First let me tell you my opinion.

This incident is definitely an accident. However...

...I'm not saying this to end the investigation quickly.

There are two major reasons.

First, just before her death, Nakata-san was drinking.

So there's a good possibility that she did trip on some piled documents...

...and fell. Then from the top of a 2 meter shelf...

...a clock weighing close to 5 kg fell and hit the back of her head.

It's unfortunate but...

...it's not strange that she lost her life that way.

Then there is the neighbor's testimony.

On the night until right before the body was discovered...

...the fact that the dog didn't bark...

...it means that she had no visitor.

In other words, Nakata-san, as the police determined...

...was all alone in her house.

In addition, I couldn't find any suspicious points...

...on the assistants' behavior.

Based on these observations, I should rule this as an accident.

But to declare it as such...

...we need to prove that it was in a complete locked room state, right?

That's right. What do you think of that house, Enomoto?

All the windows were equipped with crescent locks and...

...secondary locks with a key.

If that was the state it was in...

...as Tomoka-san had said, then...

...it's not possible to get in and out from...

...those windows to kill Nakata-san.

If that's the case, then the culprit could only have gone through the entrance.

- That would be the case. - So then...

...this proves that it was a complete locked room.

This incident is no doubt an accident.

No objections? No objections? Yep, then it's dismissed~.

- Please wait a minute. - What now?

I think this case was a murder.

Didn't I just explain it to you?

This was clearly an accident. Weren't you listening?

Well, I thought so, too until a little awhile ago.

- But please look at this. - What is this?

This is what was printed on the receipt at the scene.

According to the receipt, on the day of the incident, Nakata-sensei...

...bought four beers at the supermarket in front of the station at 5:45 pm.

But on the afternoon of that day, Nakata-sensei...

...received the same brand of beer as a congratulatory gift for the publication of her work.

What're you trying to say?

The person who bought the beer wasn't Sensei, it was someone else.

In other words, the culprit made it look like Sensei was drinking alone...

...and that person was the one who bought the beers.

But the person didn't know that Sensei had the beer in the house...

...and bought the same one.

So therefore there must be a culprit.

Suppose, for argument's sake, let's assume you are right.

Well, how did the culprit go in and out of the place?

- About that... - Enomoto had said it, right?

That it was in a completely locked room state.

At that point, murder is already out of the question.

- I didn't say that. - What?

I didn't say it was in a completely locked room state.

Then are you saying it was not an accident?

Yes. I believe she was murdered.

You think so, too? Enomoto-san.

Then what's your basis?

- The auxiliary lock at the front door. - Auxiliary lock?

The emergency service team who first received the call...

...and the first to confirm Nakata-san's death.

They went inside through the front door.

If the door's auxiliary lock was locked at that time...

..you will usually destroy the lock in order to get inside.

But there was no scratch on that auxiliary lock.

Which means, at that time...

...the auxiliary lock wasn't locked from the inside...

I find it odd.

- Why? - The area where Nakata-san's house is located...

...is prone to burglary. She got the dog for security reasons.

She also changed the front door lock to...

...a 10-pin tumbler lock with a dimple key...

...which is very effective against lock-picking.

Along with the auxiliary lock on the front door...

...there were additional locks on all the windows.

It means that Nakata-san had a very high crime prevention awareness.

So where Nakata-san should guard the most, the front door...

I don't think she would forget to lock...

...the auxiliary lock on the night she was home alone.

Serizawa-san, I think this is a murder case.

No matter how the auxiliary lock was, since one must pass through the front door...

It was a locked room because of the dog.

How could the culprit commit murder?

I do not know it yet. But...

If it's indeed murder...

...then, there is no locked room in this world that cannot be unlocked.

Kaah~...

What's with that line? I don't like it, oi.

Play on words... I'm not convinced. Eh?

Since you can't unlock the locked room... It's not murder, that's it!

Ah, whichever way you look at it, an accident is an accident.

Anyone can see, it's an accident.

I don't get it, why can't you understand? Seriously!

Everyone, please leave! Serizawa is out of the office.

He's not here, so please go!

Ah.

- I'm sorry. - Serizawa-san!

Serizawa-san, have you found anything new...

...regarding Nakata Fumie-sensei's incident? - Please calm down!

- Please calm down! - In the past...

...you have solved 7 locked room murder cases. For you to work on this case means...

..this is a murder case, right? - Please do not make hasty conclusions!

Serizawa-san, can we expect that...

...you'll be able to expose the culprit? - Expect?

- Yes, we're anticipating it. - Of course, you must have...

...some ideas, don't you, Sensei. You already know something, don't you?

Serizawa-sensei. How was it? Please tell us something.

- Oooh~. - Then...

...what are your thoughts about this incident?

- It's murder. - I knew it!

So Sensei, how did the culprit...

...enter and leave the house?

You already solved the locked room mystery, right?

- You've solved it, right? - As of now, well...not yet.

- Oh, not yet? - Eh?

- I see. - Is that so. - So then.

- Please excuse us. - Til next time then, excuse us.

Please wait a minute!

However...

If it's indeed a murder...

...then, there is no locked room in this world that cannot be unlocked.

- Oh~! - You do know something, don't you?

- Please tell us. - No no no.

Well uh. I, Serizawa Go...

...will surely derive the answer that you all will be satisfied with.

- Oh, as expected! - By the way, Serizawa-sensei...

...why are you obsessed with locked rooms?

Uh, no. I'm not obsessed at all...

Well, it's just that, it's my attitude towards work.

No, actually it's my view of life... It is like...

Hey there.

Ah. Serizawa-san, what happened?

I brought you something to eat. You must be hungry by now.

- This is unusual. - No, it's not.

The two of you have been working hard.

So how's it going? Have you solved the locked room?

No luck at all.

I guess, this time, like what you said...

...this was probably an accident. - What?

What you have said made perfect sense.

Oi, oi, oi. Hold on a minute.

You must be joking. No matter how you look at it, it's murder.

What? But you said it awhile ago, that it was an accident.

That was then.

Don't jump to conclusions. Think slow and thoroughly.

Just as in the beer and the auxiliary lock, there are too many things that looked odd in the scene.

Then there are those two assistants.

They said they were not the culprit but...

...they purposely came to tell us that.

Now that I think about it, they really look suspicious.

With all these questionable conditions, can you still...

...say that it was an accident? Anyone can see that it was murder!

- But there's still the locked room mystery. - The locked room mystery...

...doesn't matter at this point. The motive is the most important thing here.

Let's investigate the motive...

...then determine who the culprit is!

You're right. Just sitting here and thinking about it won't solve anything.

I will go and interview Tomoka-san.

Let's eat.

I'll get you some tea.

Rikako-san had been with my aunt for 10 years now.

Aunt Fumie was very strict with work...

...so there were many who quit working for her.

But Rikako-san followed Aunt Fumie no matter what...

...and had always served he as her senior assistant.

Meanwhile, Asami-san had just started a year ago.

She was very talented...

...and Aunt Fumie was particularly kind to her which was unusual.

As far as I know, their relationship with my aunt was good...

I can't find any reason that they would want to kill her.

What about the relationship between the two assistants?

I think it was probably very bad.

Aunt Fumie had always entrusted important work to Rikako-san.

Gradually, she started entrusting them to Asami-san.

Along with the task of character design which...

...Rikako-san was never entrusted with.

For someone who had been working for 10 years and to be overtaken by a new employee...

...it must have been mortifying for her. So...

"Oh, dear~. I wonder if it was because of the earthquake yesterday?"

But Asami-san has some temper too so...

"Wow, so fast."

"Not at all. It actually took me awhile."

"Well done."

"Are you still doing that?"

"Sensei was grumbling about you..."

" 'Been here for ten years, and she's still useless.' "

I see. Both assistants...

...didn't like each other...

...there's no reason for either of them to kill Nakata-san.

- I did check around but... - There must be something.

Serizawa-san! Aoto-san! Something bad happened!

- This is awful. - I just came inside...

...and saw this. I think the person entered from that window.

Enomoto-san did say this area was prone to burglaries.

I tried to preserve this room in its condition at the time of the incident.

The watches weren't taken.

Huh?

This K9 thing...?

"Oh."

It's Rikako-san's?

I see. While this room was in the state of the incident scene...

...there must be something, an important clue in this room that could identify the culprit.

Anzai Rikako had vandalized the house to erase that.

I knew it... This incident was a murder.

Do you know what time this room was vandalized?

I came here yesterday to organize my aunt's belongings.

I went out around 4 pm...

When I came back at 9 pm, it looked like this.

There's no doubt about it. It's mine.

But I didn't vandalize the room.

- I think it was done by some burglar. - Then why was it there?

I must have dropped it when I came to see you.

I haven't been over there since then.

Is that the truth?

Where and what were you doing...

...from 4 pm to 9 pm last night?

Oh. I was in a manga cafe in front of the station.

Hey. How was it?

Rikako-san's alibi is solid.

Again, back to the drawing board.

It's a complete dead end. We still don't know who the culprit is...

Maybe we should solve the locked room mystery first.

Locked room mystery, huh? In short, how could the culprit...

...go in and out of the entrance without being barked at by the dog...

...that's what we need to figure out, right? - Yes, it's the biggest mystery here.

- I got it. - Eh?

A dog will identify people using its sense of smell rather than its sight, right?

So when the culprit passed along the side of the dog...

...she was wearing Nakata-san's clothes.

And because the dog sensed Nakata-san's smell, it didn't bark.

But what would Nakata-san think if she saw the culprit wearing her clothes?

Besides, they say that a dog's sense of smell is tens of thousand times more powerful than humans.

Even if you wear other people's clothes, I think they can still tell the difference.

So then, uh, what about this?

The culprit dug a tunnel from the bottom of another site...

..to Nakata-san's house, like the one in 'The Great Escape'? (1963 American movie)

You really believe that?

Then what about this?

BowLingual. You remember BowLingual?

It's a device that let you have conversations with a dog. We can use that.

The dog must have seen the culpit.

So we could use the device to ask it.

Like 'Why didn't you bark?' Or 'What's the name of the culprit?'

If we do that... If...If we...

Would a dog even know people's names?

Serizawa-san, after all these investigation and still haven't come up with any idea...

Maybe this incident...

...was really an accident.

No way.

There's no way. It can't be. It can't be.

"It's murder."

"There is no locked room in this world that cannot be unlocked."

"Can we expect you to tell us about it..."

"...can you guarantee that?" - "Of course. Everyone..."

"Please trust me and wait."

- "Oh~." - "As expected."

"This level of incident is not so difficult."

- "Oh~." - "Indeed, Serizawa-san."

It's over...

My life as a lawyer is over.

Took many years to build credibility...

...you can lose it in an instant.

- I found the culprit. - Really?

- You're sure? - Yes, I'm sure of it.

Oh, well done!

Enomoto, really, good job! Thank you.

So who killed Nakata-sensei?

No. I found the culprit who vandalized....

...Nakata-san's house. - That one?

Tokyo Total Security installed 'My Home Camera System...'

...at Nakata-san's neighbor's house the other day.

The camera coverage also includes the entrance of Nakata-san's house.

So I reviewed the footages...

...recorded from 4 pm to 9 pm last night.

Then it recorded the burglar who vandalized the house?

Yes. It wasn't exactly a burglar though.

The culprit... was this person.

Asami-san?!

So then, Asami-san vandalized the house for the sake of destroying an evidence.

And then, she tried to implicate Rikako-san...

...by leaving the strap?

- I see. I figured it out. - Eh?

This locked room has been unlocked. No doubt about it this time.

Why didn't we notice...

...something so simple?! - What do you mean?

Try to remember that day...

We were able to notice Anzai Rikako's arrival...

...when the dog barked. However...

- "I didn't do it." - "Asami-san."

We didn't notice when Tachibana Asami arrived.

Come to think of it, the dog didn't bark at that time.

It means that Tachibana Asami had tamed the dog.

But I thought no one can tame the dog, aside from Nakata-san?

- That's incorrect. - Eh?

Actually, most dogs...

...can be tamed with a bait. - I see.

So it wouldn't be far-fetched if Tachibana Asami was able to tame the dog.

...If you tame the dog, it will not bark. - Then it's possible...

...for Asami-san to commit the crime? - Yeah.

- The culprit no doubt is Tachibana Asami! - Serizawa-san, you're amazing!

That is also incorrect.

Asami-san is not the culprit of this incident.

What?

Why the hell not? The only possible culprit is her, isn't it?!

It's certainly possible that Asami-san to commit this crime.

But the fact that she's not the one...

...has already been proven by Aoto-san.

- Me? - It was the case of beer.

I believe the culprit didn't know that Nakata-san received those beer...

...and incidentally bought the same ones.

The beer were delivered in between 1 to 3 in the afternoon.

But on that day, Asami-san was there working...

...from 9 am to 5 pm.

It means that Asami-san...

...should have known that such beer have arrived.

Therefore, Asami-san isn't the culprit.

Then why did Asami-san vandalize the house?

Me? I thought it was a burglar?

About the dog... I was able to tame it...

...because I like dogs, and I had been feeding him everyday so...

..I was able to tame him without meaning to. - On June 12, at 8:12 pm...

..you showed up sneaking into Nakata-san's house.

The security camera from the neighbor's house recorded your image.

It was you who vandalized Nakata-san's house, right?

The culprit in the murder is her.

I wanted her caught as soon as possible. That's why...

"I don't know what to do now that Sensei is gone."

I wanted everyone to suspect her.

But Asami-san, why do you think...

...Rikako-san is the culprit?

Are you hiding something by any chance?

We got the motive.

And now, how can we solve the locked room mystery?

- Uwah~. Ah... - What's the matter?

Is this a 'Mosquito..?'

- I got bitten awhile ago, too. - No. A different one.

It's a machine that gives out high-frequency sounds that only young people can hear.

It's used to drive away young people who loiter...

...in parks and convenience stores.

I guess people around Serizawa-san's age...

...cannot really hear it.

Ah. This... So, this is the 'Mosquito.'

- You can hear it? - Uwah...I thought I'm hearing something...

..I hear something that keep telling me to go away...

I feel like something is telling me... Geez...

Uwah... No more. Argh... What the hell... Ah~

Tsk. Ah.. Ah~.

Uwah~. It's nasty. Ah. Ah~.

Areh? Enomoto. Is it that one? Has it come, as usual? Oi.

- Ah. Serizawa-san. Your ears? - Eh?

Ah! Uwah~. 'Mosquito.' Ugh.

Gimme a break already. Oi. Kaah~. Argh.

I see.

So that's how it was.

The locked room...

...has been unlocked.

- What do you want to talk about? - We finally understand.

Why you killed Nakata-sensei.

Ah. What are you saying?

You really are a cruel person.

You killed Sensei who had taken care of you for 10 years.

Rikako-san, you were...

...scheduled to be fired as Nakata-sensei's assistant.

"Wow, you're really fast."

You had been intensely jealous of Asami-san.

"She was grumbling... 'Been here for ten years and still useless.' "

You feared that Sensei will take Asami-san...

..and abandon you someday.

But you have ten years of trusting relationship. So you feel secure somehow.

But...

"Have you heard about this? 'New assistant'..."

"...she's not looking for additional, if you know what I mean."

"Sensei was grumbling about you before."

" 'A worthless assistant like Rikako-san can be replaced anytime..."

" '...Maybe it's time to replace.' Well, good night."

("...Been for ten years and still useless...")

("...A worthless assistant like Rikako-san can be replaced anytime...")

("...Maybe it's time to replace..." "...Can be replaced anytime...")

("...Can be replaced anytime..." "Useless... Useless...")

("Useless.")

At that moment, everything you've built for ten years...

...are all lost.

So you held a grudge against your Sensei.

Because of your strong feelings towards Sensei made your hatred even stronger.

Then...

Your murderous intent was born.

I see.

If you put it that way, I may have a motive.

Rikako-san, why couldn't you...

...believe Sensei more?

It's true that she was looking for a new assistant.

But she had no intention of firing you.

It was all a lie...

...made up by Asami-san.

Asami-san respected Sensei...

...and was jealous of your relationship that you've built over the years...

In other words, Asami-san was jealous of you...

...so she lied to you.

So there was no need to kill Nakata-sensei.

You're lying. What you're saying are lies!

Everything you're saying is nonsense!

- It's all your imagination! - That's right.

In fact...

I do not know what you were thinking.

But it is an unmistakable fact...

...that you killed Nakata-sensei.

Fact? Explain it then.

How could I kill Sensei inside a locked room?!

To go in and out of the front door of this house...

...you must first walk past the dog.

In a sense, the dog itself has become the lock.

How should we handle this lock?

This was the most important point of this crime.

First, when you're planning to commit murder...

...obviously the dog shouldn't bark.

So the culprit had been feeding the dog in advance.

And on the day of the incident, the culprit proudly walked in through door...

...and committed the crime.

I see. If you do it that way, it is possible to commit the crime.

But you do know, right?

...That the dog barks at me. - I haven't finished explaining.

There's more.. to this trick.

If others find out that you've tamed the dog...

..it may be used as evidence and you may become a suspect.

So after the culprit killed Nakata-san...

She needed to erase this evidence so she had to make the dog dislike her again.

Such an interesting idea but how can I do that?

It's easy...

Just use this.

Affection... Anger.

It is said that dogs have similar feelings as humans.

So just like people, the dog too...

...takes a long time to earn trust but...

...can also lose it in an instant.

That means, after killing Nakata-san, the culprit...

..went out of the house at one point. Then after a few hours...

..she came back again and used the K9 Canceller to repel the dog...

...and in an instant, it despised her again.

But if the dog barks...

..you feared someone may see you here...

...and if you just leave without doing anything that may look suspicious...

...so the culprit decided to become the first person to discover the body.

I understand what you're trying to say.

But...

...you're just showing that it's possible for me to commit the crime...

...But there's no evidence that I am the culprit!

Or do you have any other evidence?

It is true...

..that there is no such evidence to prove you're the culprit.

Of course, you don't.

That's because I'm not the culprit.

But after Nakata-san died...

...there is evidence that you used the K9 Canceller.

What evidence is that?

- It's this one. - What're you saying, it's only a watch.

Nakata-san has a lot of watches in her collection.

Among them, this was her favorite.

For some reason, when Nakata-san died...

...only this watch stopped on June 5, at 10:15.

But it wasn't Nakata-san's curse that made it stop.

There is a scientific reason for it.

Reason?

Each object has a specific frequency...

When it's exposed to the same frequency sound waves...

..sometimes it would malfunction. When I examined it earlier...

The quartz which is the watch's core and...

...the K9 Canceller's frequency were the same.

In other words, the reason this watch stopped on June 5, at 10:15 pm is...

The K9 Canceller which generates ultrasound waves...

...was used here which then caused the quartz in the watch to malfunction.

Four minutes earlier at 10:11 pm.

You discovered Nakata-san's body and called 119.

Then, until 5 minutes later, at 10:16...

Until the emergency service team had arrived...

...you were alone here.

This means, the only person who was...

..able to use the K9 Canceller at 10:15...

...was you.

The energy output of this foreign-made device is very strong...

Although you used it out in the garden...

...its ultrasonic waves reached this studio.

Come to think of it, I did use it. Yeah, I remember it now.

But so what? It doesn't prove anything.

I'm afraid... I only...

...used it because the dog kept barking.

I didn't use it for the dog to hate me!

Is that true?

Are you sure that you used the K9 Canceller...

....because the dog kept barking so loudly?

- Yes. - This means that at that time when you arrived at this house...

...the dog kept barking loudly. - Yes.

Even when you discovered Nakata-san's body?

- That's right. - And even when you made that 119 call.

Yes, I already told you that!

Oh, I'm sorry. Oh. Even when you made the call, right?

"Hello? Please send an ambulance right away."

"Sensei... Sensei has collapsed inside her house..."

"I understand. First..."

What is this?

You may not know but...

..every call made to 119 is recorded.

So today I went to...

...the Disaster Emergency Information Center...

...and got this from their call log data.

Well, I had to do some arrangements though...

...that's why I ran a little late.

When you made the call...

...you said the dog was barking, right?

But according to this call's recording...

The dog that should be near you... wasn't making any sound at all.

This clearly contradicts your testimony.

It means... that when you made that call...

...the dog was still tame towards you.

- In other words, it was you who... - Enough!!

That's enough.

I'm astonished that you found the clues in such a place.

As expected of Sensei. You brilliantly solved this mystery.

But I was told that it was very difficult to come up with a solution.

It certainly wasn't easy.

However, in the end, I was able to unlock the locked room...

...and discover the facts that only the dog knows.

Excellent.

Pretty impressive.

- It really is amazing. - 'Inu nomizo shiru...' (Only the dog knows)

...not 'inuno miso shiru' (dog's miso soup), okay, everyone?

Areh?

Sensei.

"Err. Anyway.."

- Enomoto-san. - Yes.

I've changed my opinion after the recent case...

Usually meek but in times of need...

...will become so dependable. - Is that so.

Really so smart, right? Those dogs.

Maybe I should get one.

- Do you know any smart dog? - I don't know.

- Eh? I thought you know a lot about dogs. - I don't know.

- Are you angry? - I don't know.

- You ARE angry. - I don't know.

- Did I say something to upset you? - I don't know.

I don't know.
