"Hey, Colin, what's wrong? You called the night watchman over to stir up the situation, and you still have the face to call me? You didn't come to invite you to dinner last time, and now you remember me?" Zhou Feiyu picked up the student card and scolded Colin directly.

“······”

"You guessed it. Colin said.

"It's not speculation, it's reasoning, I don't know why you are so dissatisfied with our exploration of the Crescent Moon, I was originally the executive director of the Crescent Society, this matter should be in charge of me from the perspective of the Academy or from within our Crescent Society, and I originally wanted to establish power in the Crescent Society this time, and my plan will be ruined if you intervene like this, if I originally investigated, it should be a win-win situation. ”

“······”

"I don't bother to care about you, what's the matter with me? ”

"I have a letter here to teach you, I don't know who sent it, but the letter says that the detective agency is written, and it should not have been sent by someone from the school. ”

"I'll give Helen a trip. ”

“······ Good. ”

After speaking, Zhou Feiyu hung up the phone and dialed Helen's student card.

"Helen, is class over?"

"What do you think? If it weren't for today's confrontation class, I would have been punished. Zhou Feiyu pressed the phone and looked at Xia Chuanzi.

"You······ Did you skip class?"

“······ Shh~~shh~"Shimokawa Zi tried to hide the past by whistling, but firstly, this didn't do anything, just covered your ears and stole the bell, and secondly, you can't whistle, hey!

Zhou Feiyu secretly complained in his heart.

"Helen, if you have time to go to the Society's office, Colin seems to have a letter to give us, although he played us before, but the big face still has to block it, OK?"

“······ I don't care, to be honest, did you really give up investigating the three incredible campuses?"

"Do you think it's possible?"

"Understood. ”

After saying that, Helen hung up the phone.

Zhou Feiyu put down the phone and looked at Xia Chuan Zi.

"You, go to class. ”

Shimokawa shrunk his neck and left Zhou Feiyu's laboratory. Before leaving, he changed the gun to Zhou Feiyu, who took the exclusive weapon he made and returned to the laboratory with a smile and began to continue to improve the weapon.

After the compulsory class in the morning, Zhou Feiyu packed up his things and came to the activity room.

The other three had arrived early, and a letter was placed on the table in front of them, sitting around each other.

Zhou Feiyu walked into the house and after greeting each other, Zhou Feiyu picked up the letter on the table.

Dear Miss Ivy Eddy,

I heard that you have a lot of insight into intelligence investigation, and in just a few days, you have cracked the three incredible schools that have surrounded Tarot Academy for nearly five years, and I am deeply impressed by you, and it is impossible to help but sigh that a woman can do it to such an extent.

I solemnly invite you to come to this place during your vacation.

Thank you very much.

Below is an address, located in the city of the Northern Union.

"Helen, letter from your hometown. ”

Helen shrugged her shoulders and said.

"Indeed, there is such a place in our country, but that place has been deserted for many years, and it is in our family's sphere of influence, I told my parents before that this land is deserted, but I don't know why my mother didn't say anything, and I didn't think about it later. ”

"What happened here?"

"I don't know. Helen shrugged.

"Interestingly, this letter repeatedly mentions the matter of solving the case, and it seems that someone wants us to solve the case. ”

"Then here's the problem, I'm sure I can't go all of them during the winter vacation, so I'll bring at most one person, which of you comes. ”

"I'll go!" Ivy immediately raised her hand.

"Well, Helen is better, after all, Helen is from the northern union of Helen City, and she is very familiar with the geography over there. ”

“·······” Ivy puffed out her face.

Zhou Feiyu shrugged.

"There are only four people in our club, and we will be open during the winter vacation, if I can be Helen as a guide, I must go, and if you come with me again, do you think you will be busy by Shimokawa Zi alone? I am not denying you, but affirming you. ”

“······ Say whatever you want. ”

"So, if there is another invitation like this next time, I will let you go. ”

"Hmph. ”

Dangdang, two crisp knocks on the door.

There was a knock on the door of the society.

"Hello, I'm here to deliver a letter, and I have your letter. With that, he slipped the letter into the crack in the door.

Zhou Feiyu walked over and picked up the letter. Then the envelope was opened.

“······”

Zhou Feiyu sighed after reading the letter and handed it to Aiwei.

Dear Miss Ivy Eddy,

I heard that you have a lot of insight into intelligence investigation, and in just a few days, you have cracked the three incredible schools that have surrounded Tarot Academy for nearly five years, and I am deeply impressed by you, and it is impossible to help but sigh that a woman can do it to such an extent.

I solemnly invite you to come to this place during your vacation. The previous invitation did not say so, but I hope that all of you detective agencies can come here, and we will give you a very good reward after that.

Thank you very much.

"I take the liberty of asking, do you usually write like this when you write letters?"

"That's right. ”

“······· I don't even know what to say. ”

As for why the name of Ivy Eddy was used in the letter, it was because according to Zhou Feiyu's instructions

Fire paint is generally used to seal letters, but fire paint can also determine the time when the letter was sent.

"The two letters were sent no more than half a day ago, and from the handwriting it appears that they were written by the same person. Zhou Feiyu made a simple inference.

"This client seems to be a little unreliable, and he still has to write two letters. Helen said.

"No, it was deliberate, the client deliberately misled us with this form of letter, and I am afraid that this matter is not simple. Zhou Feiyu picked up the two letters and looked at them carefully.

"This letter should have been written in many copies. ”

"How?"

"First of all, there are two kinds of handwriting on this letter, the first handwriting is the handwriting of the body of the letter, the words are very beautiful, but notice here, the order of the pressing strokes here, is reversed, and there is a great possibility that the person who wrote this letter is left-handed. Here, the name is written in the normal pen order, and the person who writes the name is right-handed. ”

"However, how can you tell that two letters were written by two people, so how can you tell that there are many copies of this letter?" asked Ivy.

"It's very simple, I ask you, if I asked you to send a paper invitation to the party, what would you write?"

"Of course, it is to write a unified template and then fill in the names in a unified manner······ Ahh

"Understood? This is very simple common sense, not a complicated thing, you have to remember one thing, don't think about the investigation too complicated, the most basic thing is to conform to common sense. ”

"Understood. Ivy nodded.

"If you invite us to go with us, then I will now formally vote, and I want to raise my hand to take this commission, although the reward is unknown, what do you say?"

The three of them raised their hands in tacit understanding.

"That's all there, right? ”

The crowd nodded.

"Okay, we'll go together during the winter vacation, this is the first club activity of the detective agency, so be completely prepared. ”

Helen whispered into Ivy's ear: "I guess this is a whole carriage thing." ”

Ivy shook her head: "You don't know Ciel, Ciel's is an efficiencyist, and he only brings the most basic things. ”

"What do you think? Although the end of the exam will be the day after tomorrow, the real holiday time is the end of this month, and it will still be open for business during this period. ”
