"What do you mean?"

Miwako Sato was a little puzzled by what Takato said, "You mean Kudo's reasoning, is there a problem?" ”

"Nope."

Takato shook his head, "There is nothing wrong with Kudo-san's reasoning, and it can even be said to be perfect. ”

"Huh?"

For Takato's inconsistent words, Miwako Sato and Mao Lilan were a little overwhelmed, and they didn't understand Takato's meaning at all, while Kudo Shinichi seemed to sense the implicit meaning in Takato's words, and his brows furrowed slightly.

"But, only for today's events."

Gao Yuan added.

"What do you mean? Isn't this what happened today? ”

Maolilan wondered.

"Mr. Wise means that incident from half a year ago, right?"

Kudo Shinichi already understood what Takato meant and said.

"That's right. To be precise, the incident six months ago was the beginning of today's incident. It was because of the first short circuit half a year ago that Ms. Yukari thought of this plan. ”

Gao Yuan explained.

"However, that time half a year ago, it was just an accident, right?"

Yukari Miyano on the side said.

"That's right, because the surveillance camera outside the house caused a short circuit in the rain, no matter how you look at it, it's an accident."

Miwako Sato echoed.

"Is that really the case?"

Gao Yuan said, "You must know that half a year ago, as well as today's incident, there is a key premise for stopping the operation of the ventilator after a short circuit and power failure!" ”

"Emergency battery failure!"

Kudo Shinichi suddenly realized, "Even if the power is cut off due to a short circuit, as long as the emergency battery is still there, the ventilator can still function." But the one half a year ago, and this time today, there was a problem with the emergency battery! ”

"To be precise, it's not that everything has gone wrong, but since that one six months ago, the problem of emergency batteries has not been solved."

Takato said, looked at Yukari Miyano, and asked, "Ms. Yukari, I would like to ask, why is this?" ”

"We've gone to place an order, but it's been a long time coming."

Yukari Miyano said.

"But that's weird."

Takato said, looking at Kudo Shinichi and Miwako Sato.

"Kudo-san, Officer Sato, remember how we answered when we first entered Katsuyo Miyano's house to check the emergency power supply of the ventilator, and asked Makoto Yamashita, the caretaker?"

Speaking of which, Kudo Shinichi also recalled the scene at that time, when he followed Officer Sato to Miyano Katsuyo's house with Takato and Makoto Yamashita, and when Officer Sato explained what had happened, he specifically asked Makoto Shimoyama why there was no emergency battery on the artificial ventilator.

At that time, Yamashita Makoto replied, "The battery is broken, so I took it and repaired it." ”

Thinking of this, suddenly, Kudo Shinichi paused - at that time, his mind was all about checking the trip, and he didn't pay much attention to this, so when he was talking to Yukari Miyano just now, he didn't react to the nuances of this.

"That's right, Makoto Yamashita said 'the battery is broken, take it and fix it,' but Ms. Yukari says 'It's already ordered, and it hasn't arrived for a long time.'"

Gao Yuan explained.

Considering that Officer Sato was forcibly pulling Mr. Makoto Yamashita to stay, his emotions may not be very calm, so it is possible that the statement at the time was just casual remarks. So, in order to determine this issue, I asked Officer Takagi to investigate the ventilator purchase channel at Ms. Yukara's house. After all, Ms. Katsuyo Miyano is not using an ordinary home ventilator, but a model that is common in hospitals, which is not something that can be bought simply. ”

"Yes, my mother's ventilator was purchased by asking the hospital for help."

Yukari Miyano said.

"More specifically, it's the channel of this rice flower general hospital."

Gao Yuan said, "Because of the particularity of the ventilator purchase channel, it is obviously not so easy to replace or repair the emergency battery, and the easiest way is to contact the manufacturer through the original channel, so I asked an acquaintance in the hospital to investigate whether there is a record of repairing or ordering emergency batteries." ”

After a pause, Takato looked at Yukari Miyano.

"But the result of the investigation is that there is no relevant record."

"How could it be! Didn't Mr. Yamashita say that he had already commissioned the hospital to make an order? ”

Yukari Miyano was surprised.

"Wait a minute! Do you want to say Mr. Yamashita......"

Soon, Yukari Miyano reacted to Takato's meaning.

"Because, the incident half a year ago is very strange in itself."

Gao Yuan said, "The outdoor surveillance camera will be short-circuited due to the rain, and it just so happens that the emergency battery of the ventilator has a problem." Two seemingly coincidental conditions caused the incident half a year ago. ”

"Because after that incident, I thought of using ......"

"But you'd better entrust Mr. Yamashita with ordering batteries."

Yukari Miyano was about to explain, but was interrupted by Takato and asked, "And, Ms. Yukari, don't you think there's something strange?" In your plan, you have already set up the mechanism and wait for Osamu Sawada to turn on the switch. But then there is a problem, after your mechanism is arranged, it can't be moved, that is, your black underwear has been hanging on your balcony! So, as Mr. Makoto Yamashita who often comes to your house, he will always notice that something is wrong in the long run! ”

"A set of black underwear, always hanging on the balcony, never put away. Anyone who finds out about this will find it strange. ”

Miwako Sato imagined it for a moment, nodded and said.

This kind of thing lasted for half a year. But if Makoto Yamashita feels strange and goes to check it out, or kindly reminds Ms. Yukari about it, then the whole plan will be seen through. ”

Gao Yuan said.

"But in fact, this plan lasted perfectly for half a year, and no accidents happened at all, until today Osamu Sawada stole his underwear, and it touched the mechanism."

Shinichi Kudo said, "It doesn't make sense. Either he really came to Ms. Miyano's house and didn't care about anything other than caregiving; Either that, he had actually found out, but chose to remain silent! ”

"That's right, combined with these clues, doesn't Mr. Yamashita seem suspicious?"

"So, I had some ideas and started some investigation into Mr. Makoto Yamashita. As a result, I discovered an interesting incident - seven years ago, when Makoto Yamashita was still a student, he caused a traffic accident. ”

"Seven years ago! The traffic accident that happened to Ms. Katsuyo Miyano seems to have happened seven years ago! ”

Kudo Shinichi remembered what Yukari Miyano said before, and immediately connected the two.

"Please wait a minute, you don't want to say that the person who knocked down my mother in the first place is Mr. Yamashita!"

Yukari Miyano was surprised, "It's impossible, I've learned about Mr. Yamashita's accident, and it's not the same accident as my mother's!" The man who ran away after knocking down my mother, but he hasn't been caught yet! ”

"After Mr. Akechi told me about this, I asked Yumi from the Ministry of Transportation to bring up the case files of the two accidents."

At this time, Wataru Takagi walked in and said, "After reading the case file, Mr. Akechi found ......"

"No, no need to say it!"

Suddenly, Makoto Yamashita walked in from outside the door and stopped Wataru Takagi's speech, "I did everything. ”

Makoto Yamashita admitted.

"At that time, after knocking down Ms. Katsuyo Miyano, I drove a long distance in a panic, and then I crashed into another car, causing a second accident. And because of the second accident, the previous impact marks were completely destroyed, and there were no casualties, in order to reduce the punishment, I only admitted the second accident. ”

"Then, you became the caretaker of Ms. Katsuyo Miyano, and it was because of atonement."

Gao Yuan was not much surprised by this and said.

"Yes. Although I was not punished by the law, I always lived in guilt when I knocked down Ms. Katsuyo. So after making many inquiries, I found out that the person I knocked down at that time was Ms. Katsuyo Miyano. And it just so happened that Ms. Yukari needed to find someone to take care of Ms. Katsuyo, and in order to atone for my sins, I became Ms. Katsuyo's caretaker. ”

Makoto Yamashita said.

"In that case, why do you ......?"

Hearing these words, Mao Lilan asked very puzzled.

"Biological daughters will have the idea of 'if their mother dies because of such a long period of care, let alone outsiders'."

Gao Yuan said helplessly.

In this regard, Yamashita has no denying that he has done everything he has done - whether it is deliberately destroying the waterproof function of the surveillance camera, destroying the emergency battery, and trying to cause an accident to cause Ms. Miyano Katsuyo to die. Or after the failure of this operation, it was found that Yukari Miyano had the same idea, so she was silent, waiting for the accident to happen.

So far, this incident has finally been completely resolved, and the settlement panel has also appeared in front of Gao Yuan.

"After reasoning, start closing the case"

"Comprehensive Case Closing Evaluation: S"

"Knowledge: S"

"Logic: S"

"Observation: S"

"After the settlement is completed, the overall score reaches S, the bounty is 50, and additional rewards will be issued, please select:

"Reward 1: Professional Knowledge"

[Reward 2: One-Time Item"

[Reward 3: Special Item 2]

"Detective Rating: Assistant Detective"

[Bounty: 570]

As a result, because of a series of incidents caused by a bus idiot, Takato, Kudo Shinichi and Maoriran completely missed the opportunity to eat at the restaurant they were going to at the beginning, and when everything was over, it was already a big night!

The three people who walked out of the hospital only then remembered that they had not eaten since noon and were about to starve to death, so the three of them casually found a restaurant and feasted.

"It's all because of that underwear thief, if he hadn't done something like that, making things so complicated and sad, maybe Ms. Yukari wouldn't have done such a thing!"

Mao Lilan said indignantly while eating.

"However, the ending is still good, although I don't know what's going on, Ms. Katsuyo Miyano was rescued, and even spontaneous breathing has recovered, so if it goes on like this, Ms. Katsuyo should slowly get better."

Kudo Shinichi said.

"This time, though, it's thanks to Mr. Wise."

Mao Lilan said, glancing at Kudo Shinichi, "It's not like someone, who left others to investigate, but the incident hasn't been thoroughly investigated!" ”

"Okay, don't you guys bickering."

Seeing that the two of them seemed to be about to pull the topic on themselves, Gao Yuan immediately interjected, "Didn't you just go on a study trip tomorrow?" Have fun! ”

"I don't want to go."

Shinichi Kudo said, "It's a waste of time. Compared with this, today's incident made me realize that I need to learn more about human nature and the world in actual cases! ”

Really? I hope you can say this kind of thing so hard when you go on a school trip next year-Takato thought to Kudo Shinichi with a helpless expression.

Soon, after dinner, the three of them also went home, Mori Lan was in a hurry, and he had to prepare for tomorrow's school trip, while Takato and Kudo Shinichi each went back to their respective homes.

Gao Yuan, who returned home, began to choose this reward, because he had obtained both "one-time props" and "special props", and this time he wanted to see what this "professional knowledge" that he had not chosen would be, so Gao Yuan chose "professional knowledge" this time.

Soon, new words appeared.

"Name: Magician"

"Special Effects: You have gained a better grasp of what you know about magic. At the same time, you'll learn how to perform magic tricks using the Hermit and the Star (the detective's monocle)."

Seeing this, Gao Yuan suddenly felt that a large amount of knowledge had poured into his mind - the magic knowledge that he had only simply understood now had a deeper understanding, and at the same time, he seemed to be able to understand most of the content related to the "Transfiguration Technique" that he could not understand.

But more importantly –

Takato took out the monocle named "Star" from his pocket - this was the reward for the challenge task, or was it an item that was given directly without a choice.

Before this, Gao Yuan had never used it, but now that he had relevant knowledge, Gao Yuan suddenly found that this thing was a bit powerful!

Thinking like this, Gao Yuan pinched the lenses of his glasses, then thought about the knowledge he had just learned, and with a flick of it, the metal chain on the outside of the glasses suddenly became longer and became a metal chain about two meters long, but the star-shaped jewelry at the end of the chain did not change.

Retract it again, and the chain shortens back to its original length again.

Looking at the monocle in his hand, Gao Yuan suddenly tossed it up with a coin toss, caught it when it fell back in front of his eyes, and put it on his right eye-

Sure enough, I underestimated the reward given by this challenge task!

On the other side, Kudo Shinichi, who returned home, walked into the iron gate, just opened the door of the house, and suddenly saw a white envelope, floating in front of his eyes, picked it up and looked at it, only to see only one line printed on the envelope: Challenge book for Kudo Shinichi.

Leaning against the door wall, Kudo Shinichi opened the envelope and looked at the letterhead inside, which was the same printed text:

"On a school trip, someone from your classmates will be kidnapped. If you can protect him, you win, and if you don't protect him, I win. At that time, please tear down the name of a high school detective. This is my one-on-one duel with you, however, I can give you a hint: the kidnapping location will be on the ship. ”

The following is signed: "kidnapper".

After reading this letter, Kudo Shinichi couldn't help but show a smile - "Interesting! ”
