You were involved in a case.
A kidnapping.
You still hate the kidnapper, don't you?
Based on the victim's wounds,
we think he was stabbed with a long, thin, sharp object.
We were able to pull some footprints, but no fingerprints were detected.
I understand.
Good evening.
It looks like he was posing as a courier.
Based on the shape of the victim's wounds, there's no doubt it's an eyeleteer.
Meet with the First Section Chief and put out a wide-area alert.
- Where's Kazama? - I contacted him.
He said he received a report of an unnatural death.
We're on our way to a case involving an unnatural death, right?
This is not important. You should join the robbery investigation.
Why?
Because it's the guy who stabbed you, instructor.
It's my job to instruct you.
Take out your notebook.
#10 The Ring's Requiem
- Good evening. - This way, sir.
The deceased is Nitani Kiyoka, 72 years old.
There were no noticeable external injuries. She was found by her husband, Tsuguhide.
He is a designer. Over there.
Yes, that's right.
- Uhm... may I take a break? - Yes.
- Are you okay? - Yes.
Over here.
In the frying pan is a charred fish.
Looks like it fell over while cooking.
We think she died from the poisonous gas in the stove.
We spoke to the husband.
There seems to be no problems between the husband and wife.
- I'm heading out to support the emergency operation. - We have to settle the score on Tono’s behalf.
There were two mistakes in their report.
Whether or not she died of gas poisoning, we have to wait for the autopsy result.
City gas around here doesn't contain carbon monoxide.
It's a different gas. What's the other thing?
They had marital problems?
What's all this?
Excuse me.
Is it alright if I ask some questions?
Yes, go ahead.
What do you do? I heard you're a designer.
For advertisements and pamphlets.
I know this is gonna sound crazy, but... I found a cell phone in your laundry.
Being hung up to dry?
My wife, she, uhm... has dementia.
She started showing symptoms when she turned 70 a year ago.
It's raining.
I'm going to pick up our son from school.
Stop joking around. Look, it's not raining.
Do you know where our son is?
You heard the thunder, didn't you? Looks like it's going to rain.
Did you wash this, too?
Did I do it?
I wonder if I did.
I see.
Is there anything else you want to ask him?
Yes. When your wife passed away, were you out?
I was meeting with a client of mine.
Where was this meeting? With whom?
Uh... At a Japanese restaurant called Suenaga.
With Tase Aoi from Akashiba Printing.
And?
I came back after the meeting.
I came home and there was a strange smell coming from the kitchen.
I rushed to open the window.
That's when I realized my wife was dead.
While you were out. Did you call your wife or anything?
Leaving someone with dementia alone must be scary.
I called to asked her if everything was okay.
She seemed fine at the time.
Detective, is anyone in your family...
Yes, my mother.
She's still in her 60s but behaves like a juvenile.
She even forgets about me.
I see.
Excuse me.
The telephone has an audio recording function.
Copy all the audio recordings and listen to everything.
Take all the pictures too.
Turn off the electricity switch
Be careful not to forget to turn off the water tap
Do not leave the contents in the microwave
I'm sorry for everything.
I'll talk to my brother and sister one more time.
I'll check out residential facilities.
Aren't you going to ask me where I've been?
I wanted to go home. I went to the train station.
I went to a café, had some tea. Went into a movie theater...
I see.
I thought I was going to get yelled at.
It's tough for me, too.
All right, all right...
You have to cook the rice. Is the rice ready?
- Eh? - Mother.
- Please make some tea. - Sure.
I'm going to bed.
Excuse me. Can you wind down the window?
Thanks for your hard work!
You still don't get it, do you?
I am Tase Aoi.
I'm Nakagome with the Prefectural Police Investigation Division.
Please sit.
There was a robbery, wasn't there?
Do you know about Mr. Nitani's wife?
I was surprised when I got the call. I heard she got gas poisoning.
Did you have a meeting with Mr. Nitani yesterday?
Yes, over a meal.
What did you eat?
- A full course meal. - Who ordered it?
- Mr. Nitani did. - Do you always have the full course meal?
I usually order a steak set. Or the tempura set.
Where the full meal comes at once.
Did he say anything about his wife?
Ah~ She's disappointed she lost the ring she was wearing. ... something like that.
Thank you for your cooperation.
I didn't get the sense that she was hiding anything.
I hope you’ll remember this.
The fact that she acted differently usually means that
a foreign object has been mixed into the daily routine.
Kanagawa Prefectural Police, could you open the door for a moment?
Thank you for your hard work!
The cause of his wife's death was inhalation of hydrogen fluoride gas.
Hydrogen fluoride gas is a highly toxic gas.
If an empty frying pan coated with fluorocarbon resin is heated,
high concentrations of hydrogen fluoride are generated.
Do we conclude this as death by poisoning?
No, something's a little off.
When Mr. Nitani found his wife,
I came home and there was a strange smell coming from the kitchen.
I rushed to open the window.
That's when I realized my wife was dead.
Before opening the window, shouldn't you check on your wife first?
Besides, his wife's face should look like she's been in a lot of pain.
But she looked... like she was relieved.
Oh, as for the audio recordings left on the phone,
there were a lot of recordings of his wife's voice.
She forgets things.
Every time she received a phone call she seemed to record it.
What do we know from Tase Aoi's testimony?
The foreign object that got mixed in, I think it was "time"...
That day was different from usual as they ordered a full course meal.
That means, it would took more time to eat.
- What for? - If the husband did it...
He wanted to create an alibi by taking his time,.
One more thing.
I'm beginning to see a cruel intent.
He allowed for plenty of time for his wife's death.
Instructor, do you think the husband is the killer too?
Have you ever
wanted to kill a family member?
Are you talking about my mother?
Huh... my mother?
Excuse me.
The security camera footage from the restaurant just came through.
Excuse me.
What? It's a done deal.
If Nitani did it, where's the proof?
As for that, I saw some curious things inside the house.
I don't know what it is, but... there's a strange feeling sitting in my head.
That's what you have to find out.
Unless you want to go back to working at the police box.
The uniform doesn't suit me...
- What's wrong? - Mom...
Where is my son? Where is my son?
I don't know. I'm sorry.
Where is my son?
- Where is my son? - I'm your son.
Where is my son?
Come quickly!
- What's going on? - Shut up!
Well, calm down. Calm down.
Thank you for your hard work!
- Do you need help? - It's okay!
Sorry for all the noise.
It's to catch the culprit.
Right?
Hey, the detective this time is kind of weird.
He always looks so sloppy and acts tough.
But Mr. Kazama won't dismiss him.
So maybe he's got something.
Hey...
Mr. Kazama likes strange people, doesn't he?
Like that handsome guy who likes flowers.
I'll be back.
Come in.
When can my wife be returned?
The autopsy is done, so it could be today.
I'm overflowing with memories of my wife.
When I started working for a design company I met my wife.
I was 23, and she was 45.
She was kind to me even when I didn't know left from right.
She was a capable worker.
We often played tennis with everyone in the company.
My wife was left-handed. So she had an advantage in doubles.
We were a pair without rival.
I heard that your wife lost her ring.
I gave it to her as a present when we got engaged.
Being young and broke, I bought a cheap one.
I told her I would buy her a new one.
There is a bundle of newspapers, right?
It's a knot that a left-handed person tied.
My wife did it. What about it?
I always felt uncomfortable with it.
When I first came here
I had the impression that this house was very neat and tidy.
She is a person who likes to keep things clean.
However, this was messy.
I wonder why.
My wife has spots of dementia.
Some days she's neat and tidy, and other days she's a mess.
I understand. My mother is the same way.
- It's a mystery, isn't it? - Yes, it is.
It drives me crazy when I'm dealing with it.
You just have to be patient.
Is that so?
Your mother is important.
Please have some.
Thank you for your time.
When your wife shops at the supermarket,
she always uses her point card.
I looked at the history.
She always buys fish on Wednesdays.
Can you bring him down?
You only think in terms of logic.
That's easy to say but if you don't confront him with evidence,
you can't arrest the culprit unless you drive him into a corner with reason.
- There is evidence. - Then, please tell me.
The proof is in the mind of the murderer.
You're kidding, right?
The old days of sympathetic detectives are gone.
"Please confess or else
I'll be fired as a detective." Something like that?
- Using tears to persuade? - You sympathize with the killer.
You're already a sympathetic detective.
Your mother...
Do you see the resemblance with your family?
I sometimes want to kill my mother.
Don't forget about the victim.
This is a despicable crime that took advantage of the victim's dementia.
Hmm? What's this?
According to Kanagawa Prefectural Police,
the criminal is still at large.
A 200-man team is conducting checkpoints and vigilance.
We talked to some people in town about the incident.
Hey.
Isn't this where your mother would go?
Hmm?
I hope they catch the culprit as soon as possible.
I heard that the culprit might be nearby...
Yeah, probably.
Why does Mom always go to such crowded places?
Well...
Why does she go there every Thursday?
What?
She only wanders off on Thursdays.
Newspaper clippings about Nakagome's kidnapping as a child
Good morning. Mr. Tono, it's morning.
I'll open the window.
I'll take your blood pressure.
Mr. Tono?
Mr. Tono, are you all right? Are you in pain?
What's wrong?
Mr. Tono's breathing has gotten worse!
Mr. Kazama!
Please go to the hospital. Mr. Tono's condition...
I have an appointment with the suspect.
Mr. Kazama, please! Please see Mr. Tono!
Mr. Kazama!
He's been in a coma since this morning.
His family has been contacted.
Take it.
If you can't get him to confess,
I'm taking him to the prefectural police headquarters for questioning.
You'll go back to working at the police box.
- You can do it. - Yeah, bring him down.
I found it in the rice bin.
- This ring... - I'll be straight with you.
We believe you killed your wife.
- Huh? - Your motive...
Your were getting along well with Tase Aoi of the printing company.
Your wife was in the way.
And you were tired of taking care of your wife. That's one motive.
Even so, but killing my wife?
You didn't want to pursue another woman in front of your wife.
If there's anything you're guilty of, would you be honest with me?
I have nothing to be guilty of.
I see.
On the day of the incident you went out.
Before you left, you purposely made a mess in the fridge.
Why would I do that?
You called your wife when you were out, didn't you?
Yes, I did. I asked if she had any problems being alone.
When your wife is doing something, and you ask her to do something else,
she forgets what she was doing.
My mother is like that.
She was cooking.
- Hello? Are you okay? - I'm fine.
Oh, there's a mess in the fridge, so clean it up.
You called and asked her to clean out the fridge.
Your wife forgot about cooking and started to organize the fridge.
The pan with the fish burned out.
and she inhaled hydrogen fluoride.
Your wife bought mackerel every Wednesday.
Did you ever think about that?
Why would she make mackerel grilled in foil on Wednesday?
That's what dementia patients do. Is there a reason?
There was. There is a reason for Wednesday.
To remind her where she lost her ring.
For something so cheap?
It may not have mattered to you, but it was a treasure to your wife.
She really wanted to find it.
That's why she grilled mackerel every Wednesday.
I'm sure it was lost on a Wednesday.
It must have been when she was grilling the mackerel.
This thing about Wednesday, I don't understand.
It's all conjecture, isn't it? It has no basis.
My mother also does it every Thursday.
I was
kidnapped.
What?
When I was 4 years old.
I was playing in front of my house and a neighbor kidnapped me.
He demanded a ransom.
My mother brought the money as instructed and stood in the downtown square.
The man showed up and the police arrested him.
I was taken into custody too.
- I don't remember it very well. - You remember it well, don't you?
Tell me.
What were you thinking at that time?
Not now, not here...
Tell me.
I was so...
scared.
I can't go home anymore. I can't see my mother.
The kind of fear that I had at the time...
It remains like a burden at the bottom of my heart...
What does your past have to do with me?
The kidnapping
was on a Thursday.
My mother...
Even now, she still goes to that place on Thursdays.
To me, it seemed like she was wandering about.
When I go to pick her up,
my mother turns to me and
she asks, "Where is my son?"
Mrs. Nakagome?
Where is my son?
That's what my mother said to the kidnapper.
My mother...
She forgot that I came back safely.
Where is my son?
Thursday was an unforgettable day.
That's why, every Wednesday, she grills mackerel.
You took advantage of the habit and asked her to clean the fridge.
I didn't ask her to do that.
I didn't say that on the phone.
Your wife tends to forget things.
When she answers the phone she always records it.
There were a lot of recordings on the phone.
Except for the last call.
She must have forgotten to press the record button.
Playback of 32 calls.
- This is Nitani. - This is the Water Department.
I'll be there tomorrow for an inspection.
Yes, yes. I'll be waiting for you.
Hello? Hello?
Uhm... my wife collapsed. She doesn't seem to be breathing.
No, she did press the button.
The record button has salt on it.
Salt sprinkled on mackerel.
And also on the playback button. She must have heard the last conversation.
There's one more thing.
There was a little bit of salt on it.
It's the delete button.
What is this?
Playback of 33 messages.
Yes, hello?
- Hello? Are you okay? - I'm fine.
Oh, there's a mess in the fridge, so clean it up.
Yes, I understand.
- Okay, bye. - Okay.
Thank you...
Your voice message was deleted.
So that you would not be accused of a crime.
To make up for all the trouble she caused you.
Are you going to continue to work under stress?
It's not fair, instructor.
I don't want this kind of counseling in front of the culprit.
I was able to put my feelings into words.
From now on I can control my emotions.
You're no ordinary police officer.
You've been a victim before.
You have a stronger sense of not forgiving the culprit than anyone else, and you direct it to the case.
Yes, sir.
Your instruction ends here.
Thank you very much.
Thank you for your hard work.
Ah...
It's 4:20.
Do you like flowers, instructor?
Me too.
Unfortunately, you have no chance.
I...
can't quit being a detective.
You won the race against Forensics, didn't you?
Yes!
"I pray that your dream will come true."
"Make it come true!"
Instructor...
Am I...
able to become a detective?
At the end, when he regained consciousness,
"Am I able to become a detective?" he kept saying.
Mom made it.
Where's my son?
I have already returned.
Mom, I'm here.
You're here.
Thank goodness.
- Bon appétit. - Yes.
Instructor!
I'm going with you too.
West Aoba to Kanagawa Headquarters.
Police officers arrived at Seike Soichiro's residence in Shirano town, Aoba district, Yokohama.
A man in cardiopulmonary arrest was found in the living room.
Lodged in his back, is an eyeleteer, believed to be the murder weapon. I repeat...
It's probably Tozaki.
