On Tuesday, August 15th, night, it was the return home from the Kaka Station square shopping street.

Listening to Maori on his back, Yamazaki looked at the old man, and then continued to walk forward with Maori on his back, and Lan and Conan also followed.

When he reached the corner of the alley, Yamazaki glanced at the old man who was standing there watching the four of them again, and then whispered as he walked, "Uncle, there is something wrong with this matter, let's go back." ”

"What's the problem?" asked Maori.

Yamazaki whispered, "Did you notice just now? As an old man, his skin is a little better, I think he is only in his thirties at most." ”

"What? Then why did he pretend to be like this?" Lan asked in a whisper.

"That's right, the apartment. Conan whispered, "Just now we said we were going there, and that man came out. ”

Maori smiled: "Ha, it seems that these are two thieves who have penetrated the empty door, and they have actually learned to look at the wind like this." ”

After a few moments, the four of Yamazaki walked to the street outside the door of the previous apartment, and saw a young man walking towards the apartment from a distance, so they hid in the shadows.

The young man knocked on the door, and a moment later, the bespectacled man answered the door, "Huh, Nakamoto, are you back so soon?"

Nakamoto said: "Entering the river, let's talk about this matter later." ”

Irie said, "Not bad, not bad. ”

When the two of them entered, the four of Yamazaki immediately walked towards the apartment, but as soon as they arrived at the door, they heard a small scream, as well as Nakamoto's smug laughter, "What's the use of killing the mentor, the crows are all generally black, and the next mentor must be the same as him, but you can blame him if you die......"

Yamazaki kicked the door open and rushed into the room, and found that Nakamoto was covering Irie's mouth and stabbing him in the chest and abdomen, so he took advantage of Nakamoto's stunned moment when he saw them enter and reached out and grabbed Nakamoto's right hand holding the knife, so that he would not turn the knife or pull it out.

"Bastard!" Mori shouted, then jumped off Yamazaki's back, "Lan, call the ambulance to call the police." ”

"Yes, Dad. Lan immediately took out his mobile phone.

Nakamoto reacted and raised his foot to kick Yamazaki, but was knocked on the knee by Yamazaki's right hand and took it back with a scream. Then Yamazaki pinched the knife with his right hand and pinched the tendon on Nakamoto's arm with his left hand, so that Nakamoto's hand couldn't hold the knife in pain, and Yamazaki pulled it away from the knife. At the same time, Yamazaki let go of the knife and Nakamoto and held Irie.

Maori hurriedly stepped forward to help, "Hey, can you hear me?"

"Hmm. "Irie was sweating profusely in pain.

Yamazaki said, "Don't worry, uncle, he can't die." ”

At this time, Conan brought a blanket, "Uncle, let him lie down." ”

Nakamoto saw that the three of Yamazaki ignored him, so he tried to escape from Ran, who was calling at the door, but was punched in the chest and abdomen by Ran's other hand that didn't call, and staggered back.

"Boy, don't you want to run," Mori grabbed Nakamoto by the collar, "Say, what the hell is going on?"

"I, I'm ......" Nakamoto didn't know what to say for a while.

Yamazaki asked, "Mr. Nakamoto, you must be the old man outside, right? Why did you pretend to be an old man and stop us from coming to this apartment?"

"It should be this. Conan pressed the rewind button on the tape recorder on the table, then pressed the play button, and played a recording of the same argument Irie and another person they had heard outside.

Lan came over after the call and asked, "What's going on with this recording?"

"Do you want to talk about this? That is, Mr. Irie was alone in the room just now. Maori said.

Lan asked, "But why did Mr. Irie do this?"

Conan said, "Sister Lan, didn't we hear that just now? Mr. Nakamoto mentioned killing the mentor. ”

Mori said, "Yes, it must have been the two of them who conspired to kill their mentor, Mr. Irie made the alibi, and Mr. Nakamoto did it." As a result, Mr. Nakamoto suddenly changed his hexagram......"

Conan said, "Uncle, maybe he planned it that way. ”

"At first?" asked Maori, confused.

Conan said: "When he mentioned the blame, he must have prepared in advance, such as designing their mentor to be alone. ”

"Well, that's right. Maori touched Nakamoto's pockets and found that the pockets of his pants were bulging, and when he opened them, he saw that they were gloves and a bugging, "I see, I want to use the bugging device to make people think that your plan to kill your mentor is known to your mentor, so I will kill Mr. Irie and blame you." ”

Lan said, "But the bugging device is not necessarily installed by their mentor. ”

Yamazaki said, "I think their mentor stole their research or something, so it makes sense that the reason for the bugging device was to hear what they were going to do." And in this way, the blame plan makes sense. ”

Lan asked, "Why is that?"

Yamazaki said: "When their mentor died, there is no proof of who is the result of the research, and only if the mentor is alive and his companion is dead, and Mr. Nakamoto tells the police that there is such a thing as stealing the research results, the police can find out from their mentor that he stole the research results of Mr. Nakamoto and Mr. Irie, so that the research results are Mr. Nakamoto's." At the same time, the murder of a bad teacher who stole the research results of his disciples is also acceptable to the world, and the other suspect, Mr. Nakamoto, is more likely to escape. ”

Lan said, "I see. ”

At this time, the sound of an ambulance came, and Yamazaki and Mori carried blankets and sent Irie out.

Soon after, the Twilight Police Department led a team to arrive, and then took all four of them away, Nakamoto and Mori. Yamazaki had no choice but to make a phone call home on the way. ……

Metropolitan Police Department.

The transcript was quickly completed, Nakamoto's full name is Hiroshi Nakamoto, and Irie's full name is Irie Takayuki, both of them are doctoral students in the Graduate School of Toto University's Graduate School of New Field Innovation, Environmental Studies, and Marine Technology and Environmental Science, and their mentor is called Irimura Shunichi.

According to Hiroshi Nakamoto, Shunichi Irimura stole a paper by Hiroshi Nakamoto and Takayuki Irie, and they hold a grudge, but Shunichi Irimura has a high prestige, and they have no evidence, so they want to kill Shunichi Irimura for revenge.

When discussing the murder plan, Hiroshi Nakamoto suddenly thought of a way to get the paper back, which was to kill Irie Takayuki and blame Irimura Shunichi, as long as the police investigated and said that Irimura Shunichi stole their papers, the police would investigate to the end, and maybe they could get the papers back, so he offered to kill Irimura Jun's family, and let Irie Takayuki make an alibi, and then create the illusion that Irimura Shunichi had eavesdropped on their conversation, and killed Irie Takayuki to blame him for going to Irimura's family.

At the same time, Irimura Shunichi's family has gone out to play tonight, and Irimura Shunichi is the only one in the family who sleeps at home, and Irimura Shunichi does not have an alibi, so as long as there are audio tapes and bugs, the plan to kill Irimura Shunichi to blame Irimura may succeed. ……

In the early hours of the morning, Officer Chiba sent the four Mori home. ……

Miyamoto house, living room.

Seeing that Yamazaki was back, Mei Daiko brought the supper to the table, and Yamazaki ate the supper alone and talked about tonight.

Mimiko Miyamoto smiled, "What do you think?"

Yamazaki sighed, "How to say, the future is determined by the present. As soon as I met, I could see that the old man was pretending, and I also thought that he had something to do with the things in the apartment. ”

Mei Daiko asked, "Then why didn't it be exposed?"

"I don't think the people in the apartment are doing bad things, and the bad people don't have to come out and meet us, but when we want to go to the apartment, the fake old man comes out, so I think there's a problem," Yamazaki said. It's just that if I expose the fake old man, it won't help the whole thing, it's not illegal to dress up as an old man, if the people in the apartment are watching downstairs, exposing the fake old man will only startle the snake, and we have no excuse to enter the apartment, even if we call the police, the people inside will have time to deal with evidence and other things, so I want to observe again. ”

Mei Daizi smiled: "As a result, this delay almost killed someone." ”

"Yes," said Yamazaki, "but if I expose the fake old man, I don't have any evidence for the police to arrest him, and the same goes for the people in the apartment." And in this way, this murderous thing will be postponed, and maybe it will be successful. ”

Mei Daizi said with a smile: "Now that Irijiang is not dead, I shouldn't be killed by that guy in Nakamoto in the future, so to speak, as a result, this delay saved a life." ”

Yamazaki said: "Yes, these are the two different consequences of two different choices in one thing, but there is no way to test the results of the other choice, so whether my choice is good or bad is a confusing account." However, fortunately people are still alive, and they are not the worst. ”

Miyakoto Miyako said, "Okay, it's not early, you can eat quickly." ”

Yamazaki said, "Mom, leave it to me here, you and Dad go and rest first." ”

"It's fine. Miyamoto said. ……

Later, Irie Takayuki was educated for intent to kill, Hiroshi Nakamoto was sentenced to two years for attempted murder, and Irimura Shunichi stole his disciple's paper because there was no strong evidence, so it was finally closed, but the name of Irie Takayuki was added to the paper. ……

Wednesday, August 16, morning, Maori Detective Agency.

When Ran took the letter from the mailbox, he found a power of attorney from Shizuoka Prefecture. ……
