On a warm spring afternoon, I went to Guoli on a whim to visit Master Yuri. Master Yuri originally lived in Kokomachi, but not long after the war broke out, he resolutely handed over the house to a friend and moved his family to Guoli.At that time, I used to make fun of the master for making too much fuss, but in the air raids again and again, my family was brutally attacked by Zhu Rong three times.In contrast, Master Yuli, who was cautious and moved to the suburbs, survived in his house in Quding.There is such irony in this world. After three fires, I was disgraced, and with the previous teasing, I was really ashamed to see Master Yuri.However, when the master saw me, he just smiled gently. Not only did he not have the same knowledge as me, but he also encouraged me.

He said: "A young man like you, no matter what kind of storm you go through, will turn around one day in the future. Even if you don't realize it, you will still exude confidence. Old people like me It is the lack of self-confidence that makes you appear to be taking every step. In other words, when a person becomes cautious in doing things, it is enough to prove that the person is getting old." Then, the master not only asked his wife to bring me some clothes that fit me, but after the war ended, he also discussed with a friend who lived in Quding, asking him to give me a room on the second floor.At present, as a disaster-stricken household, the reason why I live such a good life is thanks to the master.I can't help but feel ashamed when I think back to myself when I made fun of the master for making a fuss.

It is said that when I went to the master's mansion in Guoli to bother me that day, he and his young wife were planting sweet potatoes in the field without distraction.As soon as he saw me, he washed his hands immediately and led me to the study. "Long time no see. After that, how did the newspaper work go?" The master has beautiful and thick silver curly hair, and a dark face with the same smile as before, welcoming me. "Still the same." "I just mentioned you to my wife a while ago. I said that the pages of the newspaper have shrunk recently, and there have been no major criminal cases. I wonder if Shunsuke Mitsuki is living a life of idleness."

When the master said this, he smiled faintly. "That's not the case. Since there is still my place in the newspaper, it means there is still work to do. How are you doing recently, Master?" "I……?" "Master, you should miss your hometown in Quding, right? Could it be that you plan to live in this rural place forever and rely on sweet potatoes to support your old age?" I have been worried about this matter, so I just took the opportunity to ask.The master laughed and said, "Let me tell you, the countryside is the best place. Don't underestimate this place, it's a capital of culture! As for the matter you're talking about now..."

After the master restrained his smile a little, he continued: "You don't need to say, if there is a special case, of course I would like to deal with it, but I don't think it is possible for the time being." "What do you mean it's impossible?" "In this era, even if there is a murder case, it is impossible to be a well-planned crime. People in the world are in panic, so there is no time to spend more time and energy to draw up criminal plans. What's more, only in a society where the world is peaceful and human life is respected In the middle of the world, murders will cause people's uneasiness. However, in this era of reckless disregard for human life, I'm afraid... Don't you think so?"

"In this way, there will be an era of planned murder, that is, when the master is active at the scene of the case. Is this good or bad?" I asked sarcastically.The master replied sternly: "That goes without saying, of course it is good! The existence of planned crimes proves that the social order is still maintained to a certain extent. Let's take murder as an example. If you kill a few people, you will not be punished by the law." Why do people rack their brains to plan to kill people? With the progress of society, human life is valued. The more people value human life, the stricter the sanctions for murderers. Prisoners will design An intricate murder plan, isn't it?"

"In other words, the more ingenious planned crimes, the more progressive society is?" "You can say that. At least until the ideal era of zero crime comes, that's right." "Assuming that ideal era is temporarily out of reach, what will happen to Japan in the future? Will the era of progress like the master just said really come?" "Yes. If this era of disregarding human life continues, it will be fine. No, it should be said that the coming era will respect everyone's life more than it does now." "Even... the sinister planned murderer will come along with it, do we still have to pray for the time when such villains will appear?"

"Well, you're right. Hahaha, the topic of our discussion seems a bit weird..." Judging from the above conversations, I think it is not difficult for readers to find that this master Yuri is the expert who used to use his abilities beyond ordinary people in criminal investigations.However, the master is neither a detective, nor does he hang up a vulgar signboard such as "private detective" on the door of his house in Kokucho-Sanbancho. Even so, Master's superb skills in this area are still widely known, and the police came to Sanban Town one after another with various cases for advice.Usually at this time, the master will first carefully ponder the content of the case, and then choose the case he is interested in to handle the case.As a reporter, I always hear about the case before the average person, so I often ask the master to investigate.But no matter what, as long as the master goes out, I must be indispensable.In other words, I am like Watson next to Sherlock Holmes, never leaving Meng, never leaving Meng.You must understand this first, otherwise you will not understand why I visited Master Yuri that day.

bother you for something.I was silent for a while before I told the whole story. "Actually, I came to the mansion today because I want to ask you for help." "What's up?" "Well..." The thing I was referring to was actually like this. Until now, some people still remember that I used to conduct criminal investigations with Master Yuri.Recently, a publishing house asked me to select cases that might be written into novels from the cases I have handled so far to write detective novels, and I accepted this request. To be honest, I have been living a miserable life recently. I can't live on the meager salary of the newspaper.However, the reason why I readily accepted the commission from the publishing house was not entirely for money, there was another reason.The boss of the publishing house said:

"I think Japanese people always do things in a disorganized way, and their way of thinking lacks logical concepts. Is this the case with casual books in daily life, isn't it? People can't help but feel that it would be great if there were some more logical novels. When it comes to logic Sexual novels, of course, are detective novels. In the future, our agency hopes to devote itself to publishing such detective novels, so I hope that you can help us no matter what..." To be given such a high hat for no reason made me feel a little drunk, and I was so carried away that I really thought that writing detective novels was to enlighten the general public.

But having said that, momentary ambition and writing books are two different things.When I was about to start writing, I realized that writing a book is not easy. Although I have the materials for writing a book in hand, it cannot be written as a news report.Another thing that bothered me was that the notebooks of previous cases had been destroyed in the air raids.Therefore, the reason why I visited Master Yuri that day was first of all to obtain the approval of the master before writing an article.Furthermore, I think the master may still have the records of the case at that time. "So that's what happened." After listening to my explanation, the master immediately nodded and said: "You can't do it if you don't write it! Just write it, don't worry about me. As long as you don't exaggerate too much, stay true to the case itself, and don't add embellishments and write indiscriminately." "Yes, I will pay attention. I want to write as authentic as possible." "Since you want to write, which case are you going to write about?" "The Butterfly Murder Case—I want to try to write about that case, what do you think?" I looked at the master in panic and pondered.After a while, the master suddenly jumped up from the chair.Just when I thought this was going to be bad, and made the master unhappy, the master took out the pencil case from the cabinet and returned to his seat. "Speaking of that, I said Mitsuki. I found an interesting thing when sorting out old books a while ago. Look, that's it. Do you remember?" What the master took out from the pencil case was a photo cut from a magazine. When I saw that photo, I couldn't help but feel a surge of joy in my heart. It shows a handsome young gentleman in a frock coat with an open hem and a top hat, with a cane tucked under his arm in a handsome manner.Glasses and a scarf were painted on his face with a blue colored pencil as if he had been pranked by a child.Needless to say, I certainly remember the people in the photos.No, not only remember, I can't forget even if I want to. It is this young gentleman facing the wind in the jade tree in the photo that injects an unusual atmosphere and color into the story I will write next. "This guy is smart. Isn't he? Mitsuki. This big slick. This guy almost made me fall, if you need this photo, you can take it. Also, remember to put me almost in The ins and outs of the reasoning dead end should be written clearly." After the master finished speaking, he laughed heartily, which finally gave me a reassurance. "Master, can I really write?" "Just write it. When it comes to planned murder, this is undoubtedly the best case. Although many of my pain points will be mentioned in the case, I can bear it." "Thank you, master. Being able to get the approval of the master has made me work harder. But then again, master, I still have a problem." "What problem?" "Well..., didn't we get involved in this case until the very end? Of course, it's okay to start writing from that part, but in this way, I'm afraid that the previous things will be unclear. It's even more troublesome What's more, because of the air raid, all my notes at that time have been burned..." The master didn't wait for me to finish speaking, he reached into the pencil case to search, and took out an old notebook. "Mitsuki, I have a good thing about this. This is the notebook of Ms. Hara Sakura's manager Kyozo Tsuchiya. I borrowed it from him to read it but forgot to return it. I just read it like this a while ago when I was sorting out the books. I ran out of the pile of books. After reading this note, you can clearly understand the whole story. If you have something unclear, how about just quoting this note from the beginning? What did you say? Tsuchiya You won't be angry, don't worry." Having said this, I am more and more impressed by the master's foresight in moving to the countryside during the war. Needless to say, of course I also remember this notebook.I don't know how much this handbook helped us at that time. The master discovered the important factors to solve the mystery of the case from the words like Tsuchiya's running account. That day, the master and his wife originally invited me to have dinner before leaving, but I politely declined their offer and left around three o'clock. "Oh, it's true. It's been a long time, and he cooks with great care, and wants to invite you to eat with him.... It's dangerous to go home too late? Then it's okay to stay here." grumbled the young lady.However, the master did not force me to stay. "Let him go. Mitsuki said he was going to start work tonight... and said he was going to write a novel." "Fiction……?" The lady's beautiful eyes were shining brightly. "That's amazing. What kind of novel is Mitsuki-san going to write?" "It goes without saying that what Mitsuki wrote must be pornographic novels." "Oh, it looks so dead. Mr. Mitsuki, don't write such low-level things. Why don't you write something intellectual... By the way, write detective novels." Speaking of this, the master and I couldn't help but looked at each other and smiled. When I got home that night, I wrote down the photos and notes I borrowed from the master, which is the story you will read next.However, I am not familiar with the way of writing novels. I don’t even know how this story will be written by me.But I can assure you that this story is absolutely wonderful.In addition, I will try to maintain a neutral position as much as possible, and present the key to the mystery of this murder case to Master Yuri fairly in front of the audience.If you are sharp-eyed readers, you will have the opportunity to find out the criminal with Master Yuri. At the beginning of the story, I decided to respect Master Yuri’s opinion and quote the notes of Mr. Tsuchiya Kyozo, the manager of female vocalist Ms. Hara Sakura.Therefore, the storyteller in the following chapters will not be Shunsuke Mitsuki, but Mr. Kyozo Tsuchiya.In addition, it should be added that this incident occurred in the autumn of the 12th year of Showa (1937).So, let us kick off the prelude to the butterfly killing incident.
