Okara left the body blocked by the banner, took off his medical gloves and gave in to Hattori Heiji with a faint smile: "You can start to reason."

"Oh." Hattori Heiji looked at Okata who left the body so easily and ended the autopsy, because in his opinion, since he was the best forensic doctor, he should have a certain degree of arrogance and confidence. He would not give up the work at hand for his reasoning. If it were him, he would be annoyed when the other party did such disrespectful behavior.

But looking at Ogata who had no passion at all but smiled, Hattori Heiji admired the calmness of this man for the first time, which was something he did not have.

Memu felt a little sorry for Okata, but solving the case is the key now.

"Heiji, what else do you need to do?" Although he was asking, he urged him to start his own reasoning earlier.

Hattori Heiji shook his head and said, "It's already possible to start." After pausing, he walked to the side of the corpse: "We saw an obvious pinhole on the neck of the deceased Tatsumura. I think Ogata, as a forensic doctor, should be very clear. When the toxin penetrates the blood of the deceased from the pinhole, he will be killed in a very short time. And a poison needle as a murder weapon has been found at the foot of the deceased's desk and is tested by the evidence collector."

Ogata did not express any expression when Hattori Heiji mentioned his name.

Everyone listened carefully to Hattori Heiji's extremely organized analysis without interrupting him. No matter how confident he was or even frivolous he was, he still had this ability through previous autopsy and reasoning.

Enjoying the feeling that everyone is listening to their own reasoning, Hattori Heiji continued to talk.

"I mentioned before that this is a murder in a secret room. There are two keys in total, both of which are in the hands of people who cannot commit crimes. Next, let me do an experiment to see if it is possible to complete such a method in such a closed study."

I saw him fumble in his pocket for a while, and finally took out a series of bundled fishing lines: "This is what I mentioned, the key item that needs to be used."

"Fishing line?" Kogoro Mori and Meguri looked at the long fishing line in Hattori Heiji's hand in surprise. I don't know when he got it.

Okata's eyes slowly fell on the fishing line, and a faint light appeared in his eyes. He looked at Hattori Heiji's confident smile and said nothing.

"That's right." Hattori Heiji took the fishing line and said to Meguro: "The deceased Tamura Moto's body size is similar to that of Officer Meguro, so Officer Meguro cooperates with me and conducts a simple experiment. Let us see and restore the situation when the case happened."

"Me?" Mu Mu was stunned, and he immediately realized that this was not a good job.

Hattori Heiji nodded: "Please contact Officer Meguri."

After confirming, Memu sat on the office chair of the deceased, maintaining the posture of supporting his chin with his elbow and sitting upright on the office chair. It looked exactly like the way Damuradun was when everyone walked into the study.

Because the two people were very close in size, everyone looked over and said that whether they were the relatives of the Tatsumura family, Kogoro and the police officers, they felt that they had a strong sense of immersion.

Next, in Okata's eyes, Hattori Heiji used the long fishing line he collected to fix it on the keychain from the dead with tape, and then used the fishing line to arrange a simple conveying device.

From the distance between Meguchi's desk and the wooden door in the study, this fishing line is like a bridge to connect. Gradually, everyone followed Hattori Heiji's reasoning and entered the picture he set.

He used practical actions to tell everyone how to unfold this technique. After the fishing line was closed in the wooden door of the study, Hattori Heiji pulled the fishing line with his hand, and the key chain that was originally stuck was cut into Megumi's pocket, while the tape was separated from the fishing line. He did all this outside the door, using the gap under the wooden door to put away this prop as the key evidence of "impossible crime".

Seeing all this, the convincing secret room technique reappeared. Even Kogoro Mouri, who had prepared some words, had to swallow the suspicion that had come to his mouth.

Because the murderer is indeed likely to use this fishing line and kill people like Hattori Heiji.

The entire crime scene focused on this high school student.

His reasoning, his confidence.

"A very simple method. Just use this and the fishing line to deceive everyone's eyes and make a place to kill people in a secret room." Hattori Heiji's eyes flashed, and he still said confidently.

Megu stood up from the office chair, maintained a position for so long, and moved his body: "Heiji, who is the murderer?" He had to lower his identity now and ask a young boy who was still in high school.

Although he served as the police department in the Search Section 1, Megu also had an assessment in the system, and the so-called assessment was directly related to the case-solving rate.

Before Okayama appeared, he had the same high school detective, which made him feel very annoying, but he had to use the other party's ability to increase the rate of case solving in his own jurisdiction.

That kid is Shinichi Kudo.

Now that I saw Hattori Heiji, the first thing that Meguchi thought of was the son of the novelist Yusaku Kudo.

"The murderer is this old gentleman, Tamura Riki!"

A sharp look flashed in Hattori Heiji's eyes under the brim of Hattori's hat, and he turned around and pointed at Tamura Riki who had not spoken out.

Upon hearing this, Tamura Riki opened her eyes wide, her whole body shook, and her face looked a little panic and panic.

Everyone looked over and looked at the old Mr. Damura whose hair and beard were gray.

It was indeed him! Seeing that Tamura Riki, who was accused of being the murderer, was so frightened. Hattori Heiji, who was good at observing micro-expressions, clenched his fists tightly. It seemed that he had beaten Yusuke Okabata, and he saw what else he had to say.

"Dad!" Mrs. Tamura looked at the old man in great surprise.

As a junior, Takamaura Takamaura and his girlfriend Yukiko Kaneki did not expect that the prisoner was this grandfather in his seventies.

At this time, Hattori Heiji said: "I remember Mrs. Tamura asked this old man to go to the living room to wait for her, and the fishing line on my hand was found in the garbage can in the living room. And as far as I know, Mr. Tamura has a hobby, so it's not surprising that he has such a fishing line."

Megu asked in a deep voice: "Is it really you, Mr. Tatsumura?"

You should know that although Tamura Riki is old, he is a university professor. Whether it is knowledge, cultivation, or the status he has left in society, it should not be underestimated.

If the father killed his son, what is the reason?

Tamura Riki's eyes showed a lot of things, which was a bit complicated. He glanced at his daughter-in-law Tamura Gongjiang who was looking over. The expression on his face paused. He lowered his head: "That's right, I did it. I am the murderer!"

It was him! Hattori Heiji's smile on the corner of his mouth became stronger after the prisoner confirmed it personally.

Whether it's a game or not.

He won.

All the forensic doctors can do is to witness themselves infer the entire incident.

Not him!

Okara paid attention to the expressions of the few of them from beginning to end. From the reasoning of Hattori Heiji, Tamura Riki was very calm. Even when he just heard Hattori Heiji suspected that he was the murderer, he only showed proper horror.

But when he looked at Mrs. Tamura, his eyes were looking directly at the other party, and his eyebrows were slightly wrinkled, which meant that his psychology was more confusion and surprise at that time.

Then after seeing the other person, Mrs. Tatsumura's eyes, it turned into an unnatural look at the ground, her lips trembled slightly, showing an almost burdened emotional disorder.

Just as Okata was about to speak, a voice sounded from outside the door!

"It's not him!"

Calm voice.

Um?

Okata was stunned, and then he reacted, knowing that someone had the same opinion as him.

The voice was very sudden, and almost everyone thought that Tamura Riki, who took the initiative to admit that he committed a crime, was the real murderer who killed his own son.

Ogata turned around, Hattori Heiji turned his head, including Kogoro Mori, Koran, and Meguro all looked at the source of the sound.

He was wearing a slightly loose, a strange blue suit, tall and thin figure, handsome face, and a slightly sweaty forehead. The man who rushed over was staring at everyone who saw him.

“Shinichi!”

Xiaolan, who was originally taking care of Conan, lay down to rest and returned to the study, saw the man, and many memories flashed from her mind and said in surprise.

New One?

Hattori Heiji was stunned, Okao watched Conan look after he came back with interest.

"The murderer is not him!" Kudo Shinichi gasped a little, wiped the sweat from his forehead, stood outside the study door, and his eyes flashed past everyone.

The surprised Koran, the surprised Hattori Heiji, the confused Kogoro and Meguru, and the Okaga who looked at him.

Everyone, every person who participated in this case and recognized Shinichi Kudo, would not have expected that this boy who had been missing for some time would appear at this place at this time.

“Shinichi!”

What exactly is the end of waiting?

Xiaolan's heart was thrilled. She thought of her cousin's words and those beautiful memories she cherished. The man in front of her was so real and completely within reach.

"Xiaolan." Kudo Shinichi didn't know how he should behave. He only knew that he was in pain, not from his body, but from his inner torture and tearing. After he became small and Conan, he always wanted to become his true self.
