"Let's not talk about whether a father would have the motive to kill his son, even if your fishing line experiment is impossible to succeed!" Shinichi's eyes became sharp.

"What?" Officer Memu was also surprised, "But...but...the experiment just now was obviously successful!"

"Take a closer look." Shinichi looked back at Hattori and said calmly.

"Just watch!" Hattori said angrily, and opened Officer Megure's pocket.

"Ding dong!"

With a soft sound, everyone's eyes suddenly widened, and Hattori let out a soft cry.

"This... how is this possible?" Hattori stared at the key that fell to the ground in shock, "I have obviously... already let the fishing line pass through the double pocket!"

"That's because Officer Megure is sitting." Shinichi picked up the key and gently opened the mezzanine in the middle of the key.

"If a person is sitting, wrinkles will appear between the clothes, which will block the entry of the key. In addition, the deceased was fatter than Officer Megure, and his pants were tighter. Therefore, before the key could enter the double-layered pocket, the connected

The fishing line was taken away!" Xinyi played with the key chain in his hand and slowly walked to the bookshelf.

"Besides, doesn't this photo look familiar to you?" Shinichi walked to the bookshelf and gently flipped through a photo.

"Lost important evidence, this is not the behavior of a clever detective!"

Hattori Heiji's head felt as if someone had hit him hard, and his mind suddenly shook.

"Lost important evidence is not the fault of a clever detective!"

……

"The fishing line you found in the old gentleman's room is everywhere in this house." Shinichi took out a handful of fishing line from his pocket, "At least I found five or six rolls of this kind of thing."

"Moreover, in order to cooperate with the murderer, this old gentleman even admitted that he was the murderer." Shinichi turned his head, looked at the silent old gentleman, and showed a sad smile, "I think, this matter

I've figured things out."

"You..." Hattori Heiji looked at Shinichi's expression blankly, as if something was blocked in his heart, and he felt very uncomfortable.

"The books stacked in front of the desk are just to cover up the ferocious expression that the victim may have left before death, and the opera played is also to cover up the possible screams. This is why the murderer did not use the classical music that the deceased often listened to but

The reason for the high-pitched Italian opera." Shinichi put down the photo in his hand and picked up the key chain again.

"Then, is it necessary to be so covert when doing this?" Unknowingly, the original provocation in Hattori's words had disappeared.

"Of course..." Shinichi turned his head, looked at Hattori Heiji, and smiled slightly, "Hattori you!"

"What?!" Hattori Heiji was shocked.

"Of course, there are also those people who entered the room together, like Lan and others." Shinichi looked around, and finally stopped at one person.

"If you say so..." Hattori's body trembled and his eyes widened.

"The only ones who can get close to the victim are all of you here, and the people who can kill the victim at the closest distance are——"

"Mrs. Tsujimura, it's you!"

"What!" Everyone looked at Mrs. Tsujimura in surprise.

"So," Mouri Kogoro finally reacted, "the victim was still alive when we entered the room?"

"That's right." Xinyi nodded, "Actually, when we entered, the diplomat was just given a powerful sleeping pill by his wife to make him fall asleep."

"But," Officer Megure looked at Shinichi with confusion, "once the body is sent for examination, wouldn't this method..."

"No!" A voice came from the side, making everyone suddenly startled.

Hattori Heiji slowly stood up, the brim of his peaked cap covering his face, "The murderer will make us mistakenly think that the victim died before we entered the room. After being stabbed by a poisonous needle, it can naturally contain anesthesia. Moreover,

She deliberately found the detective here just to give people the illusion that the murderer did not dare to kill in front of the detective." He slowly raised his head, "Is that what you mean, Kudo?"

"Yes." Shinichi nodded, took Mrs. Tsujimura's key chain, clicked it, and opened the inner layer. The pain in his chest once again made him frown, but his hands did not stop at all.

, picked up the needle and pointed it at a small gap in the mezzanine to compare. "It's really good."

"As for the motive for the murder," Hattori picked up the photo on the table, "it should be in this photo, right?"

"I guess so." Shinichi nodded, showing a slightly stiff smile, "If you are right, Miss Sachiko should be Mrs. Tsujimura's daughter!"

"Really...really?" Officer Megure stared at the photo in his hand, and couldn't help but be stunned when he looked at Mrs. Tsujimura, who was just a hair color apart from Sachiko of today decades ago.

"That's right." In the silence, Mrs. Tsujimura stood up, with a cold expression with a smile of relief, "Sachiko is my daughter!"

"Fifteen years ago..." Mrs. Tsujimura began to tell her own experience, and everyone who listened sighed.

"Kishen," the moment she was taken away, Mrs. Tsujimura turned her back to everyone and shouted calmly.

"...Yes." Guishan was stunned for a moment, then replied.

"Perhaps my status at this time does not qualify me to say anything to you, but," Mrs. Tsujimura turned her head, "Sachiko, I leave it to you." The moment the lady turned around, a crystal teardrop fell down.

Sachiko couldn't help but burst into tears.

"To actually frame a diplomat for such a thing, such a person deserves to die!"

A voice came from the door, and everyone turned around. The boy with golden eyes walked in, looking coldly at the dejected Tsujimura Toshimitsu, "I'm afraid it's useless to pretend to be a good person at this time, right?"

"Xiao Fei!" Xiao Lan hurriedly ran over, "Where is Conan?"

"Don't worry." Qianyu turned around and smiled, "I'll arrange for him to rest in a safe place." After saying that, he looked at Shinichi who was holding his chest and holding back the pain, and frowned slightly.

"..." Hearing Qian Yu speak like this, Officer Memu could only smile bitterly.

"This child..."

"I see, the reason why Mrs. Tsujimura is so cruel to Miss Sachiko is just to prevent others from discovering that they are mother and son, right?" Hattori Heiji looked at Shinichi with a hint of admiration in his tone, "But how do you know this?

?Or, are you really spying around here?"

"...Nonsense, I heard that kid wearing glasses say that on the phone." Shinichi groaned and leaned his body against the wall. The pain from his chest made it very difficult for him to even breathe.

Big beads of sweat flowed from my forehead.

"Conan said that?" Xiaolan said suspiciously.

"Well, he said that there was a strange detective from Osaka who wanted to challenge me and asked me to come back as soon as possible." Shinichi gasped, "After I came here, I happened to catch up with this big case, so I..."<

/p>

"Liar!" Xiaolan had tears in her eyes, "Hattori just told me that you didn't even ask me if I was okay on the phone. Are you really nearby? When you see me worried, you secretly

Laugh at me, right?" Xiaolan looked at Xinyi.

Qianyu looked at Xiaolan with tearful eyes: "Sister Xiaolan..."

Now his face was full of tangles, and he began to think about whether to tell her the truth, but after thinking for a moment, he chose to let nature take its course.

"Don't be stupid," Xinyi gasped and said with a forced smile, "I'm a detective! You can tell by the sound of your voice whether you are good or not!" He wanted to say a few more words to Xiaolan, but there was a tension in his chest.

The pain was so painful that he couldn't speak at all, so he had to curl up and squat on the ground.

"Xinyi! Are you okay? What's wrong with you...I...I'm going to call the doctor right now!!" Xiaolan ran out anxiously.

"I see, my reasoning was wrong from the beginning, right?" Seeing Xiaolan running out, Hattori straightened his hat, with a hint of relief in his tone, "This competition... I lost, Kudo Shinichi, you

Sure enough, you have a way. It seems that your reasoning ability is better than mine!"

"Don't be stupid." Shinichi interrupted Hattori and wiped the sweat from his face, "There is no winning or losing or high or low in reasoning."

"Because...because there is only one truth in this world."

Hattori stood there in a daze, as if something was broken in his heart, but he seemed to understand something, and there was an indescribable color in his eyes.

"Yes," Hattori turned around and took off his cap, with a smile in his voice, "I do care too much about winning or losing."

As soon as he turned around, he found that Kudo Shinichi was missing, and he immediately turned into beet-eyed: "Ah? Where is the person?"
