Not long after the forensic personnel arrived at the scene to collect evidence, Twilight also hurriedly rushed to the scene with Takagi with his hat on, and couldn't help but be stunned when he saw Gao Cheng and Conan: "Isn't Brother Maori here this time?" ”

"yes," Gao Cheng coughed, "I brought them here because these video game company employees entrusted me to find someone...... However, when I found someone, I found that Mr. Itakura had been killed for two days......"

"But that's weird," Twilight frowned, "since it's been two days since I've been dead, why haven't the people at the hotel found out?" The person who cleaned the room must have been here......"

"Well," the waiter said anxiously, "because this Itakura-san said that we were not allowed to disturb us, and he scolded us before......"

"That's what Mr. Itakura is," Naito explained, "he hated it when people came into his place of work, and once he was furious when the book on his desk was moved 10 centimeters......

Soma followed and said, "Yes, he only changes the sheets in his house once every six months, so he won't let people come into his room to clean ......"

"That's weird enough about Itakura," Twilight looked at the corpse with her hands behind her back, "Did I see him on TV?" ”

"He's Takura Itakura, 45 years old, and he's a well-known game system engineer," Takagi explains, "and he made a name for himself a few years ago because of movie CG......

"Police Department!" Chiba rushed over from outside, "I've contacted Mr. Itakura's attending doctor, and he said that Mr. Itakura's heart is deteriorating so badly that he needs to take medicine at least three times a day, and that Itakura was scheduled to have surgery as soon as this work is over......"

Twilight muttered, "So he's really sick to death......"

"It's true that it's a disease death, but it's not a natural death."

Gao Cheng waited for the forensic personnel to verify the scene and interrupted, "The victim's head was leaning on the table, but the saliva at the corner of his mouth did not leave traces on the table, and if he really died on the table, if he wanted to maintain this position, his hands must be sandwiched between the table and his body before they stiffened, but there is no trace on the back of his hand......"

Twilight was stunned and said, "But since his hands and feet are stiff, he should have kept this position all the time......

"What if someone tied him up?"

Gao Cheng looked at the corpse in a fixed posture: "What if Mr. Itakura was just tied up by someone, and then he was disguised like this?" ”

"Tie up?"

"Yes, Mr. Itakura's hands are probably tied to the chair with his hands on his chest, so he can't take medicine when he gets sick...... Wait until the aftermath to put it on like this. ”

Gao Cheng walked to the corpse with both hands.

"This is a murder disguised as a natural death."

"Murder ......" Twilight asked, looking at the medical examiner, who was still examining the body, "Are there any signs of binding on the body?" ”

The forensic doctor glanced at Gao Cheng and responded: "Although there are no obvious signs of restraint, a slight bruise caused by external pressure can be seen from the shoulders to the top of the knees......

Twilight rubbed her chin in confusion, "What's going on?" ”

"I guess I wrapped Mr. Itakura's body in a quilt first," Gao Cheng said with the corners of his mouth raised, "The murderer may have used something to make Itakura fall asleep first, then wrapped it in a quilt and put it on a chair, and then tied it tightly with duct tape, probably with a pillow or something between his chest and knees......

"The best evidence is that there is a little bit of duct tape on the table legs and chairs, and the quilt seems to have been washed."

Gao Cheng's gaze turned to the three Naito.

"When I was waiting for the police officer to come over, I had already checked with the hotel, but three days ago, someone pretended to be Mr. Itakura and called the hotel counter to say that the phone in the room was broken...... Yes, I found it the same way I did. ”

Naito's face changed slightly: "Wait, wait a minute, Detective Joto, you shouldn't be suspicious of us, right?" ”

"We entrusted you to help find Itakura because we couldn't help it, besides, how could a criminal deliberately bring a detective to the scene of the murder?!"

"That's what the prisoner thinks," Gao Cheng shook his head, "because if you brought me to the scene of the murder, you're not a prisoner?" A few days ago, I met a prisoner who used me as an alibi, so what can I say? ”

"This ......"

The long-faced young man said, "Even so, at least we have to come up with evidence to prove that we have been here, right?" ”

Gao Cheng said in a deep voice: "I don't have evidence yet, but I know that Mr. Itakura has left clues." ”

"Clues?"

"It was the deceased's ankle, and the left foot had obvious bruises left by the socks, but the right foot, which was also wearing socks, had no marks......"

The forensic doctor next to him took off the cotton socks that Itakura was wearing, and sure enough, he found something unusual: "How can this be?" ”

"It's very simple," Gao Cheng smiled, "The murderer put a sock on his right foot after the deceased's death, waiting until the blood was out of circulation, probably the second time he returned to ......the scene to dispose of the body, worried that the police would find out and feel unnatural."

The forensic doctor pushed his glasses: Is it really good to be so professional? Grab a job? From the time of determining the time of death, I don't give a chance at all, are all the detectives so good now?

Twilight pondered, "Could it be that Itakura took off his right sock?" But why did he do it? ”

"Just try it with you tied up like Mr. Itakura."

"Huh? I? ”

Twilight pointed to herself, and with Takagi's help, she moved her chair back to the leg of the table.

"Uh...... Mr. Itakura was tied here at the time, and the sock on his right foot was ......"

Twilight's fat body sat on the chair, imitating Itakura's posture of being tied, and he took off his right sock with difficulty with his foot, and his face changed instantly after seeing the Go board in front of him and the chess pieces arranged on the board.

"This—this is ...... Did he want to swing these pieces with his feet? ”

"In other words, this is a message before death," Takagi wondered, "but what exactly did he write?" It looks like it's just a game of Go......"

"Just think about it for Mr. Itakura, how do you leave a message when the murderer may return to the scene? Of course, you can't leave information that is clear at a glance, or even that the murderer can understand. ”

Gao Cheng's gaze turned to the three Naito: "If you can't let the murderer see it, but you have to let others pay attention, what should Itagura-san do?" In addition to the murderer, there are two other people looking for him, so it is best to get the information to the attention of the other two so that there is a chance to convey it to the police......"

Twilight looked at Naito closely, "So out of the three of them, two of them can understand Itakura's pre-death message?" ”

"Huh?"

Naito wiped his sweat and gathered in front of the chessboard: "But I really don't know what that means?" ”

The long-faced young man pondered bitterly: "If you want to say anything, it's just that this game of chess is a bit strange, in the rules of Go, if you surround the opponent's chess pieces, you must take those chess pieces, but the white chess pieces that are surrounded in this game of chess are still placed on it and not taken away......"

"That's what Itakura-san is for," Takatari continued, "Mr. Naito, is the arrangement of these sunspots familiar?" I just noticed that Mr. Itakura's computer keyboard has a similar pattern on it as in the elevator, right? ”

"Yes, yes," Naito remembered, "Mr. Itakura, like me, has poor eyesight, so he learned Braille...... So take the white pieces on the chessboard, and the remaining black pieces...... Is it just Braille? ”
