My neighbor's name is Conan

The waiter at the mahjong parlor said with some nostalgia: "Wow, I still remember these people. They were all customers who often played mahjong here a long time ago. I liked them very much. I really miss them."

Takagi Shigeru and Sato Miwako looked at each other. They didn't expect that they would actually find this "one in a million" chance.

So Sato Miwako quickly asked: "Excuse me, do the three of them often play mahjong together? Do you know who they play with?"

The waiter thought for a moment and said, "Yes, the three of them used to play mahjong together every Saturday. They would gather at 10 o'clock in the evening and start playing. At that time, there was a college student who often played cards with the three of them."

Upon hearing this, Gao Mushi immediately asked: "Excuse me, do you know who that college student is?"

"Well, I don't know. I only know that he was a college student studying criminal psychology. The other three seemed to call him 'Pingdong' and lived nearby at the time. Although the four of them were of different ages, they seemed to get along well. When they played mahjong, they always talked about the cases that happened in real life.

For example, the murderer was the husband who appeared in the interview, and the crime method used medical knowledge. And they were right almost every time, which was surprising! Because the four of them were so special, I was particularly impressed and I still remember it now. "The waiter said.

Miwako Sato and Wataru Takagi looked solemn when they heard this.

The other person is actually studying criminal psychology!!!

And this person is very likely the murderer of three people.

No wonder, no wonder that case 20 years ago was so difficult.

Although the waiter didn't know the other party's identity, he studied criminal psychology, his last name was "Pingdong", and he lived nearby 20 years ago. This was already a clue, and he would find out if he continued to investigate.

Twenty years ago, there were not many universities near Beika Town that taught criminal psychology, and there was only one university, Beika University.

There are not many people with the surname "Pingdong" in Neon.

Just ask the school for the roster.

After Sato Miwako and Takagi Wataru reported this clue, Superintendent Matsumoto personally contacted Beika University and asked for the roster of those years.

Aoki Matsu had just finished lunch when Shiratori Renzaburo, who went to Beika University to check the roster, got news that among the students who studied criminal psychology in those classes, only Pingdong Douji met the three conditions.

After hearing what Inspector Megure said, Chiba Kazunobu quickly said, "Ah, I remember he just did a program on TV about this serial murder case, and the host asked him whether the police could arrest the criminal.

His answer was, 'Now that it's almost the end, I think it will be difficult to catch him. In my opinion, the murderer has already drawn the curtains, unplugged the telephone line to completely cut off his contact with the outside world, and then hid in the quilt, trembling all over, waiting for the next three days to pass smoothly.

In order to avoid attracting attention, you must keep throwing safe cards and get through this round. If not, just come to me. 'At that time, his expression was very confident, and he said, 'The premise is that you are prepared to let all your efforts of hiding for 15 years go to waste.'"

"'Continuously throwing out safe cards to get through the round' is obviously a term in mahjong," said Aoki Matsu.

Superintendent Matsumoto turned his head and looked at Inspector Megure, "Immediately determine the current location of Hiratake Doji."

The witness, the waiter in the mahjong hall, is enough.

The waiter was an employee of the mahjong parlor and was old, so it was understandable that he didn't read the news. But as a 21-year-old college student studying criminal psychology, how could Ping Dongtangci not read the news? Because at that time, all the information about company recruitment was in the newspaper.

The case was all over the news at the time. As a mahjong friend of the three victims, he did not take the initiative to come forward and explain the situation to the police to eliminate his suspicion.

Now, of course, there is a lot of suspicion.

"Yes!" Inspector Megure responded and quickly ordered his men to investigate.

Then, Superintendent Matsumoto ordered: "Go to the TV station to get a copy of the video and show it to Guo Jing Yonggui. Ask him to identify whether Pingdong Tangci's voice is the murderer's voice."

"Yes!" Inspector Megure responded again.

Currently, the Metropolitan Police Department has two clues to identify the murderer of the serial murders.

The first was a 30-centimeter-long scar on the murderer's back from a slash by Superintendent Matsumoto.

The second is that when the murderer was killing the third victim, Guo Jingjin, his son Guo Jingyonggui was sleeping in the bedroom and was awakened by his father's groaning in the living room. He was just frightened at the time, and it was not until Guo Jing's wife came home that Guo Jingyonggui came to his senses. He even received treatment for his mental illness for several years.

Therefore, Guo Jing Yonggui was very familiar with the voice of the enemy who killed his father and could ask him to help identify the murderer.

Soon we knew Ping Dongtangci's current situation. He had returned from the TV station and should be at home now.

After receiving the news, Inspector Megure immediately selected the people, brought weapons, and led by Chief Inspector Matsumoto, a group of people rushed to the apartment where Pingdong Douji lived, ready to arrest the other party.

Although Ping Dongdouji escaped from the hands of Inspector Matsumoto 20 years ago, that was the time when he was at the peak of his physical strength. Otherwise, he would not have chosen to use electric shock to make the victim faint before killing someone for the third time.

What's more, this time the enemy is in the light and we are in the dark.

Ping Dongtangci asked the security guard to help him knock on the door. As soon as he opened the door, he was caught by the criminals who rushed over and arrested him.

Superintendent Matsumoto personally lifted up Heitake Doji's clothes and checked his back.

There was a hideous 30-centimeter-long scar on Ping Dongtangci's back.

Suddenly, Inspector Matsumoto's aura rose.

Afterwards, Ping Dongtangci was taken back to the Metropolitan Police Department.

This time, the most skilled interrogator in the Metropolitan Police Department was responsible for interrogating the other party.

At first Ping Dongtangci naturally denied it, but with the evidence presented by the police, some interrogation techniques, and the identification of two witnesses, the mahjong hall clerk and Guo Jing Yonggui, Ping Dongtangci finally pleaded guilty.

As for his motive for murder, it sounds ridiculous.

It was because when they were playing mahjong, the topic of "perfect crime" came up, and the four of them had different opinions on whether it was possible to "secretly take away the policeman's gun without being noticed by the patrol officer."

At that time, Ping Dongtang decided to take action to prove that the "perfect crime" was indeed possible.

However, Ping Dongtangci thought he would be praised, but the two older men pointed at him and said that he would never play mahjong with criminals again. Fearing that his deeds would be exposed and affect his future, Ping Dongtangci killed the two men.

The reason why Ping Dongtangci did not help to kill Guo Jingjin 20 years ago was because Ping Dongtangci said that it was Guo Jingjin who asked him to do that, so Guo Jingjin was threatened by him and became an accomplice and shared the same crime.

But Guo Jingjin really couldn't get over it, so 5 years later he proposed that they both surrender together, but unexpectedly Ping Dongtangci used the same method to kill them.

The song he was whistling was "Let It Be" by the Beatles, the last single released by the Beatles before McCartney announced his withdrawal from the band. It is said that "Let It Be" contains the lyricist's hope that the band will not disband.

After listening to Ping Dongtangci's interrogation, Qing Musong shook his head and wondered what was going on.

Everyone was just joking, but you were the only one who took it seriously and did it. It feels so scary.

But the question is, could Ping Dongtangci, who was still a college student at the time, tell which words were jokes and which were true?

There is a huge gap between the thoughts of adults and those of college students.

All I can say is that Ping Dongtang learned criminal psychology in the wrong way the first time he studied it.

Criminal psychology is a discipline that studies criminal psychology and behavioral patterns as a reflection of society.

Ping Dongtangci had obviously learned the wrong thing and was completely immersed in the situation, forgetting about the fact that it was a "crime and illegal".

Of course, judging from the subsequent situation of Ping Dongtang, he might be another self-righteous genius. Because he is very talented in criminal psychology and can understand it at a glance, he has a superior mentality that others are fools.

So he was confident that the police would not be able to catch him because of his crime.

But no one expected that Aoki Matsu would cheat and arrest him within the last three days of the statute of limitations.

Considering the fact that he killed four people, one of whom was a criminal, he will probably be sentenced to death.

Of course, being sentenced to death in Japan and actually being executed are two different things. But as long as you are sentenced to "death penalty", at least everyone still has some hope in their hearts.

Qing Musong also saved the unlucky child Guo Jing Yonggui by arresting Ping Dongtangci in advance. Guo Jing Yonggui naturally wanted to kill him with a knife to avenge his father, but now he has no chance.

As for Guo Jing Yonggui, Qing Mu Song had no ill will towards him. Although he was a murderer in the plot where Qing Mu Song did not intervene, it was still the same saying that revenge for one's father was not wrong.

As Aoki Matsu had guessed, in the subsequent court trial, Pingdong Tangci was sentenced to death, but there was no specific execution date.

But the case has come to an end.

While Aoki Matsu and others were busy with this case, other people in the Metropolitan Police Department were also busy.

After the Investigation Division arrested the murderer, the news was reported for two or three days, but the heat died down. When Qing Musong finished his work, he found a newspaper and saw that there was a piece of news occupying the front page headlines of major newspapers.

There is no need to think too much about the person who can be so popular and have such a big reputation. There is only one person in the world of science, and that person is Kaito Kid!

Even Kudo Shinichi cannot compare to Kaito Kid in terms of presence and popularity.

Aoki Matsu followed Suzuki Sonoko's route and also ran to Suzuki Jirokichi's villa to watch the fun.

After all, Aoki Matsu knew what case it was the moment he saw the notice.

Kaito Kidd, who had always written his notice horizontally, unexpectedly sent a notice vertically this time, which read: Please be prepared! Consultant Suzuki, stop struggling in vain, like a baby at the mercy of others. When the bright moon is swallowed by the night, I will appear in your family's heirloom treasury, please wait for my arrival. Kaito Kidd!

Isn’t this the dog of Suzuki Jiroyoshi? It was accidentally locked in the big vault. As a result, the old man Suzuki Jiroyoshi forgot the password and left the backup password on the dog. Then - he was doomed.

This big vault is not an ordinary vault, but "iron lithium".

"Iron Lithium" was created by the famous mechanical engineer Kichiemon Sanmizu at the end of the shogunate. It is said to be the strongest safe that no one can break.

There is a large silver turntable and 12 code dials of different sizes on the door of the vault. If you turn the code dials randomly, arrows will be shot out and axes will fall. After the axe falls, a puppet will extend holding a fan with "Success or Failure" written on it.

The safe is 4 meters deep and the area is the size of 6 tatami mats. It is surrounded by 50 cm thick iron plates and there is a 3 cm gap under the door. It is easy to open from the inside, but only Suzuki Jirokichi knows how to open it from the outside. There is a weight sensor in the room, and once it reacts, the iron fence will surround the entire room.

Such a strong vault is naturally well protected against theft, but it would be painful if you forget the password.

After searching everywhere for the door of the safe and finding no one to open it, Suzuki Jirokichi could only bow his head and ask his old rival for help. He then sent a fake premonition letter to attract the attention of Kaito Kid, and drew him over to help open the lock of the safe and rescue the dog.

For this reason, Suzuki Jirokichi not only rarely bowed to his opponent Kaito Kid, but also cooperated with the opponent's actions - even if it meant tying him up.

I can only say that the dog is lucky to have such a good owner.

After all, there are many people who don't take a dog's life as a life.

In this case, even Conan let Kaito Kid off, so Aoki Matsu would naturally turn a blind eye.

However, Nakamori Ginzo had a serious expression on his face, especially when looking at the notice letter.

Because not only was the letter written vertically this time, the sketch of Kaito Kid's head on it was not like the one Kaito Kid had drawn before. Nakamori Ginzo was not sure whether this letter was sent by Kaito Kid, or if some other thief had stolen it under the name of Kaito Kid.

As for Ginzo Nakamori, he asked Jiro Suzuki why he told the media this preview letter whose authenticity was uncertain.

Suzuki Jirokichi's answer made Nakamori Ginzo want to hit someone. He put his hands on his hips and said cleverly, "Let everyone think this is a real notice first. If I win, won't my heroic legend be further expanded?"

Ginzo Nakamori was speechless on the spot.

Suzuki Jirokichi wanted to use this method to dissuade Nakamori Ginzo from leading the Second Investigation Section to get involved, but Nakamori Ginzo regarded catching Kaito Kidd as his lifelong goal, so how could he not get involved?

Despite knowing that the notice letter was likely a scam, Nakamori Ginzo still treated it with the highest standards.

He quickly mobilized the detectives of the Second Investigation Division to surround the entire Suzuki Jirokichi villa. Everyone was on high alert and would never let any suspicious person escape.
