Conan: I can hear the murderer's voice

Twenty years ago, a doctor was first stunned by an electric shock gun and then killed by a Liben knife.

Three days later, another university professor was killed with the same Liben knife.

Soon after, Officer Morimura, who was in charge of investigating the case, was hit and killed by a car driven by the criminal while checking for a suspicious vehicle.

Matsumoto, who was a rookie in the police force at the time, chased the murderer all the way to the dock, but was slashed in the left eye by the murderer with a Ribonu knife.

Five years later, fifteen years ago, another lawyer was murdered in the same way.

Except for the police officer who died in the line of duty, the other three victims were first electrocuted and then the murderer carved capital letters on their bodies with a sharp object.

Moreover, all three died in their own homes and there were no signs that the door locks at the scene had been pried open, so the police concluded that the perpetrator was an acquaintance.

However, until the statute of limitations was about to end, the investigation had not made any progress.

Fortunately, the criminal psychologist used his life to help the police extend the prosecution period of the case.

When Matsumoto Kiyonaga arrived at the crime scene and saw the capital letter "Z" carved into the back of the corpse, painful memories instantly came back to the mind of the administrator.

He left the study room where the body was found and instructed Megure beside him:

"Have you notified Lin Xuan? We must ask him to help solve this case!"

[The murderer chose to continue committing crimes before the statute of limitations expired, which was a blatant provocation to the police]

[If the case cannot be solved quickly, the entire Metropolitan Police Department leadership will have to resign under public pressure]

Megure was already used to hugging the detective's thigh, he quickly said:

"I sent Officer Sato to pick up Lin Xuan a long time ago."

When Lin Xuan was respectfully invited by the police to this high-end apartment, he was surprised to find that the Junior Detective Team was also in the living room.

Finally, she waited for her beloved, and Huiyuan immediately told her everything she knew:

"Brother Lin Xuan, the victim lived in the same apartment as Ayumi. The detective team came to Yoshida's house to play today."

"When I went downstairs with Ayumi to buy drinks, I noticed a strange man with a bushy beard and hair, whistling, but we didn't pay much attention to it at the time."

Conan was extremely speechless.

[Hey! Your elbow is bent outward?]

[I am a member of the detective team, but I told the information to my competitors? ]

Lin Xuan squatted down and touched Xiao Ai's hair affectionately, and said with a smile:

"Thank you for your help. I will definitely catch the murderer as soon as possible."

Xiao Ai's heartbeat suddenly accelerated and her face turned a faint pink.

Sato suddenly lost his composure.

【what's the situation? 】

[Even elementary school students are not spared? 】

Afraid of being misunderstood as a pervert by the aloof female police officer, Lin Xuan quickly stood up and seriously confirmed with Officer Matsumoto:

"Is it convenient to check the crime scene now?"

Conan sneered.

[Humph, you arrived just now. I had already deduced from the death message that the murderer this time was actually a copycat.]

But all his reasoning and investigations were to help Lin Xuan.

When I pushed open the study door, I saw a corpse with the murderer carving a striking letter "Z" on its back.

The criminal expert leaned over the computer on the desk with his upper body, his left hand on the keyboard and his right hand tightly grasping the mouse cable.

His butt was still sitting on the chair, and there was a burn mark on his neck from being attacked by an electric shock gun.

A large amount of blood flowed out from the Z-shaped wound, staining the chair and the floor underneath red.

Chiba said:

"The deceased said he had an appointment with an important guest in the afternoon and declined his original four o'clock social engagement. We speculate that the guest is a major suspect in the crime."

"It is preliminarily inferred that the perpetrator first attacked the victim with an electric shock gun, and then used a sharp object to inflict wounds on his back, and the victim eventually died from excessive blood loss."

"The murder method is exactly the same as the three cases that year."

Shiratori felt a little strange:

"I didn't expect that the letter carved on the body this time was not N. According to the file records, the letters carved on the bodies 20 years ago and 15 years ago were 'E', 'S', and 'W'."

Yuan Tai didn't understand, and asked his companion in a low voice:

"Why did the police think the letter on the fourth body should be N?"

Mitsuhiko explained in a low voice:

"The first three letters represent the directions of east, west and east. If the same murderer continues to commit crimes, it is very likely that he will carve a capital N for north on a new body."

But this time, the letter left on the back of the murdered criminal psychologist was a capital "Z".

Ayumi bent over and tilted her head to look at her dead neighbor:

"If you look at it from this direction, the letter becomes a capital N."

Megure didn't care about this anomaly:

"After all, before the criminal is arrested, we have no way of knowing what the purpose of the letters he carved is."

"But the murderer who committed the crime and provoked before the end of the prosecution period must be the same guy from that year!"

"The police had never disclosed to the media the information about letters carved on the back of the body. It is impossible that other criminals wanted to imitate the crime."

The police captain explained to Lin Xuan the conclusion drawn by the police officer based on the current situation:

"The prisoners saw the psychologist on a TV show and challenged him."

"So he sneaked into the apartment and killed the expert. The man who whistled that Huihara and Ayumi witnessed was the culprit."

The police's reasoning logic is self-consistent, but Lin Xuan knows that in the world of science, the police's reasoning is mostly used to eliminate wrong options.

Plus, the Death God elementary school student hiding behind the door was staring at him with ill intent.

[Hurry up and accept the police's reasoning, so that I can use the name of the reasoning to let everyone know that Lin Xuan's reasoning ability is not even better than that of an elementary school student! ]

Even though Conan had "reminded" him like this, Lin Xuan would certainly not agree with the police's investigative ideas.

He put on gloves, lifted the upper body of the deceased and scanned it with his eyes, then shook his head at Megure and said:

"I'm sorry, Inspector, I'm afraid I can't agree with your conclusion."

Hearing Lin Xuan say this, the person who reacted the most was not the police officer whose investigative idea was denied, but Edogawa Conan who was standing behind the door.

[Lin Xuan only lifted the upper body of the deceased and glanced at the keyboard, and instantly realized the death message left by the victim? ]

[How is that possible? I was observing the room for more than ten minutes before I discovered it.]

[How could Lin Xuan lock onto the clue in one second? 】

Megure quickly asked the detective:

"Brother Lin Xuan, what's wrong with our thinking?"

Lin Xuan did not answer directly, but looked at Conan who looked unhappy:

"I guess I'm not the only one who noticed."

"Conan, I'll give you a chance to perform."

Conan: "..."

You didn't even notice the death message.

【You want me to help you? Dream on! 】

However, after the previous case, everyone present, especially the members of the Junior Detective League, believed from the bottom of their hearts that Lin Xuan's reasoning ability crushed Conan.

Yuan Tai urged:

"Hurry up and tell me, the detective team finally has a chance to show off their skills in front of the police."

Conan showed an extremely embarrassed smile on his face. He would never use his discovery to help Lin Xuan show off in front of the police.

However, silence was understood by everyone to have another meaning.
