"I'm glad you came,......" Sasaki introduced Kudo into the living room and sat him on the sofa, then brought the tray over, placed the black tea and cut cheesecake in front of him, and then sat down across from him, "But I'm sorry, because it's too sudden, and that's the only thing left in the house, I hope Mr. Edogawa can be satisfied......"

"No, let's cut straight to the case. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info" Kudo waved his hand, not wanting to be polite any longer.

But as soon as he said this, Sasaki's eyes immediately turned red, and his voice was a little low: "Yes, it's still the most important case...... Mr. Edogawa, my brother must not have been killed by accident, someone must be playing tricks - please help me find out the truth!"

"Since I am here, I will definitely find out the truth of this case. ”

"Thank you so much!"

"If you want to say thank you, let's talk about it later...... Miss Sasaki, I remember you mentioned on the Internet that you found a blank piece of paper in your brother's drawer, with the words "I wish to meet you again" written on the front and the sentence "If you don't become a virtuous person, then you will be trampled to death as grass", I wonder if you can take that piece of paper out and show it to me. ”

"Of course, please wait a minute. ”

Sasaki hurriedly got up, walked over the sofa where Kudo was sitting, walked to the cabinet near the corner, stood on tiptoe and took down a box from it, then walked back to the sofa and sat down, opened the box, carefully took out the gloves inside, put them on, and then took out the paper and handed it over.

Kudo was slightly stunned when he saw her movements.

"Because I think it's something very important, I can't leave ......fingerprints," Sasaki explained.

"You didn't leave any fingerprints when you first got this paper?"

"Yes, I happened to be packing my bags, so I put on my gloves as well. ”

"Did you show this piece of paper to the police and have them fingerprinted?"

Kudo put on the white gloves he had bought at the convenience store as he took the note from Sasaki and rummaged it up and down.

Sasaki whispered yes.

"Yes...... But the police only found my brother's fingerprints on it......"

"Does your brother like to drink black tea?"

"Ah, no, I don't like it, and even he's a little allergic to black tea......"

"Then your brother is not alone in touching this piece of paper. ”

"Huh?"

"The front and back of the text are printed – I thought when I saw the photo, and it was only after I got the real thing that I realized that it was drawn with a pen. And someone grinded mint into juice, mixed it with ink, and dipped it in writing, and if you look closely, you can smell it from this envelope. ”

“…… If it smells, then I didn't notice it earlier, and the police should have found out!"

"I smelled something similar in black tea. ”

"Yes, yes, I added peppermint, which relieves the headache...... Well, I needed this lemon tea to relax after my brother died......"

"So you get used to the smell and you don't feel anything special when you smell it again. As for the police, they may have smelled your body and thought that the smell on the envelope may have been brought by you. ”

“…… What do you mean by that, do you think the murderer is me?"

"Nope. ”

Kudo began to fold the note, and at the same time began to explain lightly.

"The smell on the note doesn't come from you. ”

"You just took it out of the sealed box a while ago, and it can't have picked up your smell so quickly, and if it does, the gloves on your hands will smell of mint. ”

"So the killer should be someone who loves mint as much as you do – most likely the woman in black you mentioned online. ”

"But that's about that later. ”

"Miss Sasaki, can you let me go to your brother's room first, and then take me to that café?"

Kudo looked at Sasaki.

His eyes turned a bottomless blue at this point.

Mint?

Hehe.

It's so much fun.

The word for mint is "meet you again", there is also a flower language for "virtuous man", and there are myths about mint that mention the trampled grass - which is consistent with the contents of the envelope.

What's more......

Kudo remembered.

Kurosawa Gin's involvement in the sender incident, the name of the person who made the payment is Mojito, the date of invention of this wine is exactly 1910 mentioned in the letter, and this wine also uses mint materials.

If this case had nothing to do with the organization, he would have committed suicide!

Kudo entered the room under the leadership of Sasaki, and began to look for clues in silence but seriously.

He noticed the notepad on the table, which was clearly torn several pages.

"My brother is venting his emotions. Sasaki explained, "When he's not happy, he likes to tear up the pages of his books and crumple them into paper balls and throw them on the ground, and I've tried to crumple them, but the lines are just scribbled on them." ”

"Now what about the paper balls?"

"Ahh......h ”

"Why do you take a picture since you think it's garbage?"

"I thought there were clues to these paper balls, so I kneaded them apart and took a photo, but in the end, I didn't find anything ......."

"Can you show me your phone?"

"Okay, okay, and I also filmed my brother's room when I first entered his room after his death......"

Kudo didn't talk, just took the phone handed by Sasaki and looked at the photos.

Oh, and he narrowed his eyes.

"You took sixteen different photos?"

"What's wrong?"

"This photo shows only eight paper balls on the ground. ”

"Because the front and back of the crumpled paper ball are drawn lines......

"Sure enough. ”

"Ah, what?"

"Do you have a pen?"

"Yes, yes, please—"

Kudo took the pen, walked over to the table, pushed the notepad there, and then looked for the patterns on the photo and traced them one by one.

He also drew sixteen patterns on the front and back of eight sheets of paper.

There are always two sides to the paper, and when it is crumpled into a ball, one side is always facing inward.

Kudo found the pattern on the inward side and turned the eight sheets of paper more or less, and after turning them, he began to fold the paper according to the lines on the paper.

After a while, there were eight more strange origami patterns on the table, and Kudo changed the angle to put them all together.

After piecing it together, the lines that were originally on the outside of the paper were combined into a pattern.

“た…… の…… し…… Sasaki, who came over, read out the words softly and couldn't help frowning, "Happy?"

That's the message he wants to convey. Kudo said as he took a picture with his phone.

"But, how do you know you'll find his message this way?"

"First, you say that he writes scribbling lines to vent, but the person who scribbles will only scribble on one side of the paper, and he won't leave the incision so flat when he tears the paper. Second, the eight paper balls shown in the photo were clearly deliberately placed on the ground. Thirdly, the paper ball is not kneaded into a paper ball after your brother has drawn the note, but is first folded in a special way, and then spread out into a paper ball, and then kneaded into a paper ball. To sum up, it is easy to come up with the news. ”

"Good, so powerful......"

"Miss Sasaki, can you think of the meaning of the word 'happy' on this?"

"Please give me a moment...... Oh yes! My brother seems to have such a folder in his computer file, but my brother said that only men are interested in the things in it and there, and only men can be happy...... Sasaki's voice suddenly became squirming and pinching.

......" Kudo Shinichi, "Don't worry so much now." Can you open your brother's computer and find that file for me to see?"

"When, of course ......"

Sasaki hurriedly turned on the computer, pulled the computer chair and sat down, and when the screen lit up, it took her a little time to find the file, but she needed a password to unlock it.

"This ...... What to do?"

"Try typing in your brother or your birthday. ”

Sasaki tried, but it didn't work.

Kudo Shinichi frowned, but he thought of something, squatted down, groped under the computer desk with his hand, and soon touched something, he tore it off, took it out, and found that it was a note with a complex mix of numbers and letters on it.

"That's the password. ”

"How did you know there would be—"

"This folder is important to your brother, so it's no surprise that he would set a complex password. But it's easy to remember complex passwords, and most people will write notes and hide them in this place to keep a wake-up call. ”

"Worthy of a detective. ”

Sasaki exclaimed, entered the password, and sure enough, the file was successfully opened.

At the moment of opening, Sasaki subconsciously covered his eyes with his hands, but he couldn't help but open his fingers with curiosity, and glanced at the contents of the folder, but he couldn't help but exclaim: "Oh my God, what is this!"

Sasaki's face changed drastically, and she instantly sat upright, pulling down with the mouse, and looking at the folder at a glance.
