The whole world knows that I crossed

It was a slightly crumpled gum wrapper.

It looks unremarkable and can be seen almost everywhere.

Jin Tianyi carefully spread the note across the handkerchief, so that the white side of the paper was exposed in front of everyone.

The Jianzhi Police Department narrowed its eyes, and took a closer look...

"——This is?!" He couldn't help exclaiming.

I saw some small squares drawn irregularly on the white paper. There is a distance between the two lines, dividing these small squares into two symmetrical parts. Some circles circle the small squares in groups of four. A medium sized square, and a large rectangle enclosing all these patterns.

Among them, in the "small grid" surrounded by a smaller square in the upper left corner of the rectangle, the small square in the far left corner is surrounded by a striking red circle...

"This is the 'token' agreed upon by the two murderers in this exchange of murders, or it can also be called the 'instruction map'."

Jin Tianyi's face no longer had that kind of ease and complacency.

He looked serious. Obviously, the reasoning has reached this point. Most of the deciphered part has been completed, and the rest is to unravel and restore the criminal's modus operandi.

And this is the part that every time, although he is not bored, he doesn't really want to do it.

Because after restoring the modus operandi and producing evidence, the criminal basically has no possibility of sophistry.

It is good to be able to bring the murderer to justice.

But in many cases, Jin Tianyi is not willing to face his crimes after his crimes have been fully exposed and he has realized that he can no longer escape the punishment. He uses aggressive, resentful, or tearful gestures to tell his reasons Prisoners who committed such crimes.

Maybe the vast majority of them are not the kind of hopeless guys who are born to feel pleasure in hurting others, maybe after every crime, there are enough to make the prisoner trample on his life, and he must do the same. doing, or reason for grief or despair.

But so what?

Kindaichi may be able to understand the motives of those people, but it is absolutely impossible to agree with their actions.

And in the end, what's the point of those statements except that they can be exchanged for a sigh?

The people who were killed and died will not be resurrected, and the tragedies that have happened cannot be rewritten.

This is the saddest part of every case.

Even though he had experienced it many times, Kindaichi still couldn't get used to this kind of thing.

He sighed silently, seeing that most of the people in the carriage were looking at him with eyes half curious and half urging, he continued his reasoning:

"As you can see, the 'target' marked on this instruction map is not the dead person we saw, but the one sitting opposite her—"

"Miss Matsusaka, it's you."

As Jin Tianyi said, he raised his eyes and looked at the beautiful girl who was sandwiched between Mo Lilan and Nanase Miyuki, whose face was so pale that she might faint at any moment.

She has waist-length curly hair dyed a certain light chestnut color, a small and delicate face, a slender figure, and a certain kind of fragile beauty in her whole body. She is a girl who is easy to feel protective.

At the same time, when the first murder happened, the unlucky girl who was hit by the bruised, hideous and terrifying death of her friend attacked the upright girl.

At this time, Kindaichi's deduction made the pale girl's bloodless cheeks become almost as pale as snow.

"What do you mean?"

She spoke with great difficulty.

"You mean...it was me who was supposed to die at that time?"

Tears slowly pooled in the girl's eyes.

She looked a little hysterical, and shouted like a breakdown:

"And this is because Rina wants to cooperate with others, please kill me?!"

"Impossible...it's impossible! Rina would never do this! Why do you slander her so much?! She's already...already..."

Ms. Matsusaka was completely speechless.

She clasped her arms tightly around her chest, staggered and fell into the seat behind her, looking fragile and helpless.

A trace of unbearableness flashed across Jin Tian's eyes.

However, now, it is impossible for him to stop reasoning or choose not to reveal the truth in order not to puncture the last illusion in the heart of a girl who almost became a victim.

The teenage detective sighed again.

"Whether you believe it or not, whether you can accept it or not, this is the truth."

he said calmly.

"In the plan of the two accomplices, one of the two victims who should have died was you, Ms. Matsusaka."

however--

"Because of a certain change, the person who died changed from Ms. Matsusaka, who was originally selected, to Ms. Asakura herself, one of the murderers."

"What is this variable?"

One by one, Kindaichi glanced at the group of members of the drama club who were also members of the drama club, including the deceased Asakura Rina and Ms. Matsusaka, who covered her face and wept silently.

"It was one of the two companions who, out of some coincidence, broke Miss Asakura's plan."

"This person may have been unable to stop Ms. Asakura, or it was too late. In short, he or she chose another way to prevent Ms. Matsuzaka's death."

——That person replaced the instruction map that Asakura Rina had prepared originally, showing the location where Ms. Matsusaka was sitting, into a picture pointing to Asakura Rina's own location.

And Asakura Rina, who was unaware of this, just replaced Miss Matsusaka and died at the hands of her partner...

"—Wait! Kindaichi, isn't this too strange?"

The Swordsman Police Department couldn't help interrupting Kindaichi's explanation.

He frowned, very puzzled and said: "If it's like your reasoning, then Miss Asakura shouldn't be the first victim, right?"

After a simple investigation, the Jianchi Police Department has determined that the second victim also died of poisoning.

Although the means of evidence collection are currently limited, they are temporarily unable to know what kind of poison the two victims were infected with, but the second victim died nearly 10 minutes later than Rina Asakura, and Rina Asakura was already dead. Next, how did she poison the No.2 deceased?

Jin Tianyi lifted the hand holding the gum package:

"That's how it works."

Sword holding Police Department:? ? ?

"...how did you do it?" He looked confused.

Kindaichi continued to shake the chewing gum package in his hand:

"Take advantage of the victim's habit, Police Department."

"Although we were sitting far away, because they had a fierce quarrel before, it seemed that everyone was blaming one person, so I paid a little attention and found that Mr. Yamazaki seemed to like chewing gum very much. Basically, I have to chew a piece every once in a while."

"And when the tram stopped at the last stop, I accompanied Miyuki to the platform to do some shopping, and went to the restroom by the way. When I came out, I happened to see Mr. Yamazaki who had just come out of the smoking area being stopped by a lady. After a short After the conversation, he handed a pack of chewing gum to the lady, and the lady took one carefully, and returned the rest together with the packaging to him..."

The Jianchi Police Department suddenly realized: "So that lady is Ms. Asakura? The poison was put on the chewing gum package at that time?"

"...There is such a possibility."

Kindaichi didn't say anything to death.

After all, they still haven't figured out what kind of poison is in the victims and what are the lethal conditions.

But that's okay too.

In short, it does not affect them to find the murderer.

Jin Tian's eyes became firm again.

"I'm just saying that even if Ms. Asakura died before Mr. Yamazaki, it's entirely possible to use Mr. Yamazaki's habit of wanting to chew gum every once in a while and kill him after her own death."

"And how Miss Asakura herself was poisoned to death..."

"Mr. Sudou, I'm going to ask you this."

Kindaichi looked at a young man named Sudou.

He was the colleague of the No.2 deceased Yamazaki, and he was also the one who jumped excitedly at another colleague who he thought would be the murderer when the theory of exchanging murders was first stated.

When Sudou was named by Jintian, he was stunned at first, and then he argued angrily for himself:

"Why are you asking me? Do you mean that the other murderer is me? What nonsense reasoning! What are the unweaned brats talking nonsense there?! I haven't left this carriage since I got on this tram, and I have never been close to the seat where these college students are sitting! Want to say that I am the murderer? Yes, can you show me the evidence? No? You want to imitate others in reasoning games, are you too young? [Small] detective."

Kindaichi was not at all offended by the sarcasm and derogatory tone in the other party's tone.

He just glanced at Mr. Sudou calmly, and his tone was cold:

"So, this is also the most remarkable thing about you, Mr. Sudou."

"You didn't leave the car the whole time, and you didn't get close to where Ms. Asakura and Ms. Matsusaka were."

"But you not only successfully received Ms. Asakura... No, it should be said that you accidentally discovered the plan of the two of you, so the person who secretly handed over the 'token' prepared by Ms. Asakura according to the method you agreed in advance , left the target information, and successfully followed this 'tip' to kill the wrong 'target'..."

"...There is no need for this kind of 'praise' to the murderer, Kindaichi, hurry up and tell me how he did it!"

The Jianchi police department couldn't help urging.

Jin Tianyi took a few steps back and came to the place where Conan had picked up the chewing gum package before.

He tapped the ground with his toes, "It's very simple, the police department," the young detective replied, "He's sitting close to the entrance and exit of this carriage, where he can pick up the 'message' that his accomplice deliberately discarded here, just by bending over. While it is convenient to receive messages, it is also convenient for him not to use any information about Ms. Matsusaka provided by his accomplice to poison her, but it is more simple and direct—”

"Remember the tip of Miss Asakura's right index finger, very close to the nail, that small wound we thought was accidentally left when trimming the nail?"

"Although it does look similar, but in fact..."

Jin Tianyi looked at the young man in a suit whose expression had completely darkened:

"Mr. Sudou, can you show us the cuff button on your right cuff?"

The author has something to say: Qiao Xiaowen’s invisible chapter_(:з」∠)_

How should I put it, in fact, the development of the reasoning plot should normally be like what we saw in the reasoning episode, first describe the process from before the incident to the victim's appearance, and show some true and false details in the middle, the real Hints and clues are mixed in, and then the detectives will peel back the cocoon, remove the false and preserve the true, and start reasoning, but here we are looking at the whole incident from the perspective of Qiao Xiaowen, and there must be no pre-plots. When writing about the reasoning process and evidence, it has to be like A lot of details appeared out of thin air, and it was also my mistake in choosing the perspective... Learn from the lesson and improve next time_(:з」∠)_
