Conan's Almighty Extraction

"You are right. My wife was indeed killed by Mr. Lanchuan's mother 20 years ago."

Masaki Katagiri admitted the matter, and asked suspiciously: "However, that is all in the past, so it should have nothing to do with this case, right?"

Before the Megure police department could speak, Nagara Haruka, who is proficient in divination, took a tarot card from the handy tarot card. After seeing the face of the tarot card clearly, he said flatly: "In my opinion, the police suspect the murderer. It's among us, I'm right, Megure Police Department."

"Eh, well. You can't say that." Although the Megure police department is indeed suspicious of the seven of them, considering their face problems, it is not easy to express it too directly.

As if to reflect the effectiveness of divination, Nagara Haruka drew out a new Tarot card and continued: "If I remember correctly, the snow stopped after twelve o'clock last night, so the snow outside the house , can't find any trace of the murderer's entry and exit?"

The Mumu Police Department no longer concealed it, and admitted frankly: "It is true, everyone here is suspicious, but it is impossible to find out who is the murderer now."

"I think there should be a way."

Nagara Haruka habitually draws another Tarot card, but instead of using divination, he reminded through observation of the scene: "Judging from the situation at the scene, even if the murderer wore a mask when he committed the crime, he There should be more or less blood of the dead on his body."

"That's true," Mu Mu Police Department's eyes lit up, and then said: "Then the murderer is someone who has time to wipe off the blood?"

Mori Kogoro nodded, looked at Kazuyo Inaba who was sitting there, and said, "The only person who has time to wipe off the blood should be Miss Inaba who didn't show up when the body was found."

"Stop joking, why should I kill the teacher?!"

Inaba and Daimeng stood up, refuting everyone's suspicion of her, and then fought with Nagara Haruka, who made her suspicious, and tore off the string of a string of pearl necklaces around Nagara Haruka's neck, causing the pearls to drop Drips scattered on the floor.

After seeing this scene, Bai Yanzhenyu's pupils shrank suddenly, as if thinking of some possibility, he hurried to the room next to Su Fanghongzi's dormitory, and carefully observed the lattice transom above the locked door.

Between the baffles of the lattice transom, Shiraiwa found that the dust in some places was obviously thinner than other places, and the distribution was not uniform. Obviously, something passed through that place, which led to such a result.

Combined with the previous inference that it is almost impossible for the murderer to leave the locked dormitory, a new possibility emerged in Baiyan Maha's mind, that is, the murderer used some props to kill Su Fanghongzi outside the dormitory.

……

After figuring out the murderer's modus operandi, Shiraiwa Maha asked Police Officer Takagi to help prepare some props, and then called everyone to this room for a public demonstration.

"Everyone should have noticed that this villa has a completely symmetrical design, so the decoration of this room is exactly the same as Ms. Su Fang's bedroom on the other side. Now I take this place as Ms. Su Fang's. In the dormitory, the quilt on the bed is regarded as the deceased, and I will show you the murderer's modus operandi."

Maha Shiraiwa walked to the door where he was locked up, and asked Officer Takagi who was carrying the props to Su Fang Hongzi's bedroom, "Officer Takagi, are you ready?"

"Okay." From the other side of the door, Officer Takagi's ready voice came from the other side of the door.

"Okay, let's start the demonstration. First, I borrowed a small knife that is similar to the murder weapon. I put an elastic band on the end of the handle and threw it in through the transom partition above;"

"Then, put another piece of elastic through the holes in the eyes of all the masks, like a bead, and then pass the same piece of elastic with the knife attached through the mouth of each mask, and when they are all put on, another thrown into the room one by one;"

"After all the masks are thrown into the room, the elastic bands can be used to control the masks. Officer Takagi, now pull the elastic bands tightly."

Since the eyes and mouth of these masks are connected together by elastic bands, after the elastic bands are tightened, these masks are naturally connected back and forth, just like Hokage stretching his neck and biting a pheasant in his mouth Like the Orochimaru of the sword, the knife was aimed directly at the throat of the dead person simulated by the kilt.

"The thickness of each mask is [-] millimeters, and two hundred sheets are three meters. Adding the gap between each mask and the length of the knife, the total is at least three meters."

"The deceased was sleeping on the bed at the time, and the distance from the lattice transom was about three and a half meters. The tip of the murder weapon was only a short ten centimeters away from the deceased's throat. At this time, just push the mask with a wooden stick or the like. , the weapon will be pierced into the dead man's throat."

"Finally, cut off the elastic band that passes through the eyes of the mask and the weapon, and the mask and weapon will fly away due to the force of the broken elastic band, causing the mask to be scattered everywhere, creating a scene that conforms to the legendary mask's curse."

"This is why only one of the masks has a large area of ​​blood on it, while the other masks only have a trace of blood on the mouth."

"So, the murderer used this method to complete the murder in a secret room without entering the room. In this way, the murderer can lock on two people."

Under the cooperation of Officer Takagi's demonstration, everyone also understood the technique of Shiraiwa Maha's explanation, but they expressed doubts about what Shiraiwa Maha said later.

"Don't you understand that?"

Baiyan Maha sighed, and explained: "According to this method, it means that when we heard the sound of the mask being scattered on the ground, the murderer was staying in this bedroom on the third floor of the East Wing."

"Therefore, Ms. Hoonami (sister maid) who was staying with us in the mask room at that time, Ms. Minaho (sister maid) who opened the door on the west side, and Mr. Matsudaira and Katagiri who came out of the west wing at that time can also be excluded. Sir and Miss Nagara."

"So there are still suspects, only Mr. Lanchuan who came to the mask hall after the sound of the mask falling, and Ms. Inaba who didn't come out at that time."

After Shiraiwa Maha finished explaining, everyone suddenly realized, and then their eyes fell on Aikawa Fuyuya and Inaba Kazuyo.

"It's not me, I didn't kill anyone!"

"It's not me either, I'm just sleeping in my room!"

Facing everyone's eyes, Aichuan Fuyuya, Inaba and Dai suddenly became nervous, saying that they were not murderers.

Although the scope of suspects has been narrowed down by deciphering the modus operandi, more evidence is needed to find out the real murderer.
