I was in Conan, and after picking up Xiao Ai, I was chased by Hongzi.

The forensic doctor looked over the body calmly and said: "No obvious marks of strangulation were found on the body of the deceased, but judging from the bruises, it appears that the deceased had been subjected to large-scale oppression from outside the body."

"How could this happen?" Officer Megure was a little confused.

Otoi Hiroshi put his eyes on the bed, and everyone followed him.

"Ah! This blanket is so soft and warm to the touch~" Conan said mischievously, standing on the bed.

Mao Lilan hurriedly ran over and picked up Conan: "You can't touch..."

"But why does this blanket feel sticky?" Conan said, grabbing the blanket.

"So that's it!" Officer Megure suddenly realized.

When Mouri Kogoro was confused, Otoi Hiroshi explained: "The prisoner probably used that blanket to fix Mr. Itakura on the chair, and then used tape to wrap around and around the outside of the blanket to fix it, as long as it was between the knees and chest. Put a pillow or something to help him lean back on the chair smoothly."

"So that's it, there will be no traces left." Officer Chiba said in surprise.

"Next, the murderer used the corner of the table to fix the chair. After he died of a heart attack and his whole body became rigor mortis, he removed the tape and blanket from his body. It can create the illusion that he died of illness." Otoi Hiroshi continued.

"Okay," Officer Megure nodded and looked at Takagi Wataru, "Go and ask the hotel staff if anyone has come to see Mr. Itakura in the past two days."

"Restaurant..." Mouri Kogoro thought.

"Huh?" Officer Memu twitched his eyebrows.

"To be honest, before I confirmed that he lived here, I pretended to be Mr. Itakura and called the front desk of this hotel. I said that I was the person who borrowed chess, Go and chess from the front desk, but my phone number But suddenly I can’t fight out, please come up with a solution for me, that’s it.”

"Hmm..." Officer Megure still looked a little confused.

Mouri Kogoro continued: "The counter lady is still on the other end of the phone, smiling happily. What can I say that he is here again..."

"Well, someone should have found Mr. Itakura using the same method as Uncle Mouri." Hiroshi Otoi spread his hands.

"What did you say?!" Mouri Kogoro glared at him, "How could someone have such a smart mind like me?"

Otoi Hiroshi rolled his eyes, "We'll know what's going on when Officer Takagi comes back."

Not long after, Takagi Wataru ran back, "Officer, I asked, and the counter said that two or three days ago, there was indeed a person pretending to be Mr. Itakura and said that the phone in the room was not working. This person is very suspicious."

"Um." Mouri Kogoro's beady eyes appeared on his face, "There really are..."

"It seems that this is correct. It seems that the murderer is among the three of them." Otoi Hiroshi said.

"Eh? Why do you say that?" Officer Megure asked.

"Because when the three of them came to me, they once played a video of Mr. Itakura. In the video, he had three different chessboards placed next to him, and only the three of them knew this." Mouri Kogoro crossed his arms. It felt like a sudden enlightenment in my chest.

Otoi Hiroshi cast an appreciative glance.

"Who is the murderer?" Officer Memu asked in a deep voice.

"Didn't Mr. Itakura tell us all the answers?" Hiroshi Otoi said with a smile.

Officer Memu lowered his head and said speechlessly: "Hey, you didn't say you could hear the voice of a dead person, did you?"

Mao Lilan trembled when she heard the sound, "It's so scary."

Otoi Hiroshi smiled slightly: "Only Mr. Itakura's right ankle did not leave any traces of wearing socks. In fact, that was because the murderer waited until Mr. Itakura died and returned to the room again when he saw that the body had only taken off his socks. One sock was really unreasonable, so I helped him put the sock back on."

"What we need to consider now is why Mr. Itakura has to take off his socks?"

"So why?" Officer Megure asked helplessly.

"That's because if you wear socks, you can't grab something, and you can't make alignment movements..."

"Grab something, what are you trying to catch?" Officer Megure then asked.

Takagi Wataru looked to the side along the original position of the body. A Go board was quietly placed on the ground, "Could it be?"

Otoi Hiroshi nodded: "Yes, Mr. Itakura took advantage of the fact that before the heart medicine he took before lost its effectiveness, he used his right foot to deliberately leave a message before his death. This message was enough to identify the person. The identity of the murderer.”

"What's going on..." Officer Megure didn't want to ask anymore.

"Now I can ask you to look at the chessboard. If you use Braille to see the layout of the chessboard, you will have different discoveries." Otoi Hiroshi said.

"No, Braille doesn't have such a shape." Naito Sadaira leaned over and said.

"Ah! But it would be interesting as long as you don't look at the white chess pieces."

"So, what is it?" Officer Megure asked hurriedly.

Naito Dinghei adjusted his glasses: "I see - the fierce hand is the evidence of the horse, it is his hand watch."

"Um?!"

All eyes were focused on Souma Ryusuke.

"Hey, hey...what's going on? Is someone trying to put the blame on me?" Ryusuke Soma hesitated, with beads of sweat dripping from his forehead.

Otoi Hiroshi shook his head: "No, the murderer is you. This is because you don't understand Go or Braille, and there is something that no one else can have except you - —That’s the watch you just bought five days ago.”

"Mr. Itakura is such a particular person about watches. After meeting you, he will definitely hold his arm in his hand and inspect it. If my guess is correct, Mr. Itakura's fingerprints should be on it now."

"And how could Mr. Itakura, who disappeared a week ago, leave fingerprints on the watch you just bought five days ago?"

Souma Ryusuke suddenly let out a long sigh and began to talk about the grievances and regrets he and Soma had had for twenty years.

At this point, Ryusuke Soma was arrested, and this incident came to an end.

Because Kogoro Mouri and Officer Megure still had something to discuss, Hiroshi Otoi drove Conan and Ran Mouri home first.

The red Ferrari was driving on a road lightly paved with white snow, like a scarlet light.

The slight chill seemed to chill people's hearts.

"Otoi-kun, do you think people really change? Will they really change once they leave?" Mao Lilan held Conan's little hand and sat in the back seat.

It seemed that the story about Ryusuke Souma and Taku Itakura just now reminded him of her and Shinichi Kudo.

Otoi Hiroshi was silent, and Conan turned his head to look at her side face.

Mao Lilan raised her chin slightly: "This feeling of waiting is really hard..."

"Then do you want to try falling in love with me?" Otoi Hiroshi said suddenly.
