"That's a lot of fun."

Conan sat on the couch and drank coffee, listening to Katayama's words, and couldn't help but speak.

Furukawa had already told him what had happened during the day, and he had repeated it to Conan, wanting to communicate.

Zoro can't speak, and there doesn't seem to be a direct hint to him.

"Both of them said they had killed Mashiro, but ...... The girl's behavior is obviously more serious, right? ”

"I've roughly confirmed that a small amount of sleeping pills can't kill at all, only a little sleepiness, and Zhenbai's death is because of jumping off the building."

Conan nodded when he heard Katayama's analysis, so that neither of these two people was the cause of Mashiro's death, at least, not the direct cause.........

"But Furukawa also received the note, right? What he did. ”

"I think it should be, as the manager of the botanical garden, he should let Mashiro enter and leave the botanical garden freely."

Katayama said that, at least for now, it should be like this.

"But what did Nomura do? She's Mashiro's only friend......"

As soon as he reasoned a little bit of clues, Katayama pondered again, and now he seemed to have some outlines, but there was still no clear picture of the case in his mind.

What's missing? It feels like we're about to reach the last step.........

"By the way, how did Nomura get to the botanical garden?"

Conan suddenly asked, leaving Katayama stunned.

Furukawa said...... That kind of antique lock, you can open it with a poke......"

Katayama said suspiciously, but was glared at by Conan.

"Only the first semester of high school, it's an antique lock! In the first semester of high school, it has been replaced with a new lock that cannot be opened without a key! ”

"What do you say? But it's a matter of the first semester of high school! And Nomura she ........."

This time it was troublesome, and finally there were some clues, but it turned out to increase the suspicions...... Why is it so ......

"Could it be that Mashiro really didn't commit suicide?"

Conan looked at Katayama, he had thought that Mashiro might have committed suicide for some reason, but now it seemed that it couldn't be that simple.

"Nomura's relics are still in the classroom, I'll pick them up tomorrow."

Katayama clasped his hands on his chest and leaned against the wall, Nomura was definitely an important role in the case, after all, she was Mashiro's only friend.........

"You say, will anyone have received a note?"

Conan's words made Katayama stunned...... Are there any other accomplices? It's not impossible, because there are only a few notes at the moment, right? Maybe there were more people involved in that event.

"I don't know what else to investigate......"

Katayama collapsed to the ground weakly, and this time the matter ...... I can't say weird, it's just, it's too ...... It's so unreal...... He didn't know where to start......

"By the way, let's investigate the information of Mashiro......"

Conan pushed his glasses.

"Everything in the case starts from the deceased, so let's investigate Mashiro and Nomura first, maybe there will be a breakthrough."

Conan got up from the couch and prepared to go back to the Maori Detective Agency.

It's too late to go back, and Xiaolan is going to nag him again.........

…………

"These are the things that Nomura left at school, what, any clues?"

Furukawa held a cardboard box of books and handed it to Katayama, who took the cardboard box and rummaged through it carefully.

"Help me find out if anyone at your school has received a note."

"I inquired, but no."

Katayama choked up, apparently Furukawa had already thought of him.

"Do you think it will be my turn?"

Furukawa suddenly said, he also roughly understood what the note meant, it was equivalent to a crime notice, right?

Whoever receives the note will die with remorse, just like Nomura.

"How do I know ........."

Katayama took out something that looked like a diary, flipped through it, and the first page made him gasp......

A page full of foul language, and the paper was torn, which shows how hard she put the pen down...... The notebook was written with all kinds of resentful words in a red pen, the tip of which almost cut through the paper, and she viciously cursed everyone in her class who watched her bullied coldly.

She described her classmates in the most obscene and outrageous terms, and she wished that the tip of her pen could pierce their eyes and tear their faces.

The previous ones are probably some resentful words, which classmates with good grades are really damned, which rich classmates are really hateful, etc., are basically cynical words.

He could understand that jealousy was an emotion that everyone had, but was this girl a little too much.

It's worth the back, and almost all of the content turns into an insult to Mahaku...... Have a finger in the pie......... Crocodile tears...... Disgusting hypocrisy...... These words jumped into Katayama's eyes one by one.........

"I don't want to be friends with this freak!"

Is this guy's view of his friends? What a shady guy.........

Last page...... Only dense excuses.

In other words, at this time, the case has already happened, right? It also seems too late to apologize.........

"Alright...... Another question, the lock of your botanical garden should have been replaced in the first semester of high school, right? ”

Katayama looked at Furukawa and asked his question, and Furukawa also had a blank expression...... Yes, the lock was changed, but ...... Why was Mashiro able to enter the botanical garden.........

"By the way, when I entered the botanical garden that day, I just didn't lock the door, will you ......?"

"No way, I've always locked the door, yes, I haven't figured out how you entered the botanical garden that day!"

Katayama is dumbfounded, what do you mean? The botanical garden usually locks the door, but when he goes up, it is clearly open......

"There must still be someone...... There must be someone else behind it......... Think about it, if there is anyone else who has anything to do with Mashiro! ”

"Right...... What do you say...... There was also a classmate in the class, who was her neighbor...... Yes, there is such a number one! ”

………

The case is already eyebrow-raising, and he guesses that these children don't want to kill people at all, but want to intimidate the misfit of Mahaku, right?

In all likelihood, Nomura lured Mashiro to the botanical garden as a friend, put a small amount of sleeping pills in the water cup, and then locked the door to lock her in the botanical garden, because the door could only be unilaterally locked from the outside......

It is estimated that the sign was just taken away, and their real motive was only to intimidate her, but why did Mashiro jump off the railing in the end?

She knew there was something wrong with the Botanical Garden's guardrails...... You can't be stupid enough to lean in, right?

Also, who will be the person who sent them the note............
