That evening, a press conference was about to begin at the Matsumoto Prefectural Police Station, and the spokesman was preparing materials for his speech in a small room.

At that moment, the door was pushed open and Grigory entered.

“？” The spokesman looked at Gregory with some strange eyes. "Mr. Gregory?"

"I'll take a look at your previous draft," Gregory said. "There is progress on the case, and I need to review it to make sure that your statement is not misleading. This is a permission issued by your Commander to make changes to your statement. ”

The spokesman for the "......" glanced at the permission order and handed the speech to Gregory.

"Hmm-" Grigory raised an eyebrow. "The writing is good, but the manuscript needs to be changed."

As he spoke, Grigory handed the spokesperson a printed copy that had already been prepared. "Replace the content in this with the relevant content in your manuscript, and how to replace it is up to you."

"Huh?" After taking a look, spokesman Cao Cao looked at Gregory in front of him in surprise and said in surprise. "Are you sure you want me to say that?"

"That's right," Grigory nodded. "Even if you don't repeat it word by word, you have to fully express the meaning."

"But if that's the case......"

"I take all the responsibility," Gregory said. "That's what you read!"

"......" The spokesman hesitated for a moment, then nodded. I see. ”

……

At the same time, inside the police station.

"......" Chiba was sitting in front of a mountain of newspapers and A4 papers, flipping through the pages.

[Topic 238, accept H0 and reject H1, there is no significant difference.] 】

[Topic 239, accept H0 and reject H1, there is no significant difference.] 】

Newspapers and A4 paper were constantly flipped, and from time to time, Chiba was writing something on the blank paper next to her.

When all the information was read, Qian Yu let out a sigh of relief, and then looked at the results of the records on the white paper.

This is a list of claims, a list of math to drive the case.

"So," Qian Yu muttered as she looked at the results. "Who are you serving for......?"

…… At the same time as the rough, at a press conference in the conference hall of the police station.

"According to our investigation," the spokesman said. "We found various pesticides in the home of Mr. Yoshiyuki Kono, the first informant, and it is theoretically possible for these pesticides to create poisons that cause this effect."

"What?" The reporters present were in an uproar.

"However, according to our further speculation," the spokesman continued. "We don't think the amount of pesticide in Kono's house is enough to make a poison that can kill so much, so the police are currently investigating whether Kono is really suspicious. Therefore, we hope that the media that have previously reported on Kono's suspicion of committing major crimes will restrain themselves and abide by the basic ethics of journalists. ”

…………

Late at night, Dr. Asasa, Gregory, and Chiba are sitting on the train back to Tokyo.

"So this case is a headless case?" Mitsuhiko said unwillingly. "I thought that if you guys went out together, you would definitely be able to catch the prisoner!"

"We're not gods," Qian Yu smiled bitterly. "Anyone who has the potential to succeed is also likely to fail."

"However, this result is at least acceptable," Gray Yuan replied. "After all, when the water is clear, there are no fish."

"I think," Qian Yu glanced at Gray Plains. "It should be said that when the water is clear, there is no boat."

———— go back a few hours ago

"This list ......," Grigory said, looking at the results that Qian Yu had given him, and was silent for a long time. It's a lot of weight......"

"yes," Chiba pouted. "The Liberal Democratic Party supports the hawkish candidates of the strong-fisted policing, the rival companies of the pesticide company where Yoshiyuki Kono works, the chaebols who may buy the land, and a bunch of them."

"How did you come up with this list?" Conan asked.

"Count the amount of relevant news and their attitudes," Chiba shrugged. "If a newspaper has a more biased opinion of a group than other newspapers, then the newspaper can be considered to be serving a certain newspaper. And these newspapers were the first to break the news that Kono Yoshiyuki might be the murderer, and they were linked to other groups, and such acts were in line with the purpose of their masters. For this reason, I've overlooked some extraneous possibilities like Tokyo Greenery and Aum Shinrikyo. ”

"You've got a lot of big fish......" Grigory raised an eyebrow. It's likely that no one would have the guts to arrest them. ”

"So what do we do?" Thousand Feathers tilted their heads. "That's more than we can handle, right?"

"yes," Grigory shrugged. "The energy that can be pulled out of any one of these is enough for a few of us to die without a place to be buried. Fools would just stand up and fight them - and we can't be sure which of them did this, and if there is no further evidence, it is very likely that it will be related to the big guy who has nothing to do with this case, which is really stupid. ”

"So what do we do now?" Conan asked.

"I've already arranged this with them," Grigory replied. "I've calculated with a formula before, and if I could cause that kind of effect under the astronomical conditions that day, the amount of sarin poison gas required would be absolutely amazing, and it would definitely require a large-scale laboratory to accumulate for a long time or a workshop-level production base. Considering that they put sarin gas in an open space with inefficient killing, it means that it must not take a lot of time for them to produce this amount of sarin - so it is a reasonable inference that they have a production workshop. ”

"So you've confirmed that the other party is not small, right?" Conan asked.

"Otherwise?" Gregory squinted. "Does a person with no background still have the means and courage to do such a big thing?"

"So what do we do now?" Qian Yu asked. "Quit?"

"Yes," Grigory nodded. "And it must be to complete the exoneration of the innocent Kono Yoshiyuki while not shifting the blame to those bigwigs - even if Yoshiyuki Kono is to carry this black cauldron, it must not stimulate those bigwigs with huge energy. We are not police officers, and it is not our responsibility to solve medical problems and leave criminal cases unsolved. You contact your guardians, we'll leave here tonight, anyway, my mission is complete, and there's nothing to say about us leaving them together. ”

———— at the same time, somewhere.

"Did they really stupidly take the bait?" The young man was talking on the phone.

"Excuse me, are we going to stop them?" On the other end of the line, the man who was clearly using honorifics asked.

"No," said the young man. "Just do a little bit of stealthiness when they're away, and find out a little bit about them."

"The feast can start at any time, and before that we need to prepare a dagger in addition to a knife and fork."
