That night, in addition to the two props used to disguise suicide.
Hiroaki Buta probably gave Saki Iimori a box of Assam black tea.
The poison that really killed Iimori Saki was planted in this black tea.
Of course, all this is just Tang Ze's speculation.
If there is no evidence to support it, there are many weak points in this reasoning.
So after explaining their reasoning to Takagi, the two went to Iimori Saki's home again, wanting to verify Karasawa's reasoning.
Sure enough, Karasawa discovered several cans of high-end black tea stacked in the cabinet built into the kitchen.
"They are all empty. It seems that after Iimori Saki finished drinking, he kept the black tea can that Buta Hiroaki bought for her."
Tang Ze sighed slightly, "I cherish the other person's gift so much that I even keep the empty can after drinking it, but in the end, I met the other person unkindly..."
"Tangze Criminal, now is not the time to sigh."
Looking at the various black teas placed in the cabinet, Takagi said excitedly: "So, as long as we find the poisoned jar of black tea, we will be able to find evidence!"
Takagi said as he put on his white gloves and wanted to take all the black tea away, but Karasawa looked around the kitchen and then walked to the sink.
"Takagi Criminal, stop looking."
Looking at the Assam black tea can placed on the water control net, Tang Ze called to the other party and picked it up: "I'm afraid this is the can I drank in the end."
"But it's empty?" Takagi couldn't help but be surprised when he looked at the clean tea can with no lid on it.
Tangze took the porcelain teapot on the water control net and looked at it, then activated his super-smell sense for a moment and sighed: "As expected, it has been cleaned."
"washed?"
Takagi was shocked when he heard this: "How could it be possible? This is a tea can. Who would wash it..."
"I guess it's easy."
Karasawa thought for a moment and figured out the key to this result: "The tetrodotoxin prepared by Hiroaki Buta is colorless and odorless, but black tea can become moldy.
I am afraid that Buta Hiroaki deliberately mixed moldy black tea into it. After drinking the black tea, Iimori Saki discovered that the tea leaves were moldy, so he completely cleaned the tea set.
As for the moldy can of black tea, it was probably removed during cleaning.
"Damn it...it's a dirt grinder..."
Takagi on the side heard what Karasawa said and immediately checked the pool. He found that a waste crusher was installed in the pool on the other side of the water control network. He couldn't help but said angrily:
"Now it flows directly into the sewer. Did Hiroaki Buta even calculate this step?"
"It's just like the professor said, it's just my reasoning game."
Karasawa patted Takagi on the shoulder and told him to calm down: "But if someone who knows Iimori Saki's character and living habits commits the crime, then it is not impossible to complete this case."
"Tang Ze Criminal, why are you not worried?" Takagi looked at the calm Tang Ze and said anxiously: "In this situation, how should we bring that guy to justice!?"
"The more difficult the prisoner is, the more motivated I am." Tang Ze said with a smile: "I really want to see his expression when he is arrested."
Looking at Tang Ze's lifeless smile, Takagi couldn't help but shudder.
For some reason, he actually felt a sense of danger.
But as a companion, Takagi felt relieved in the next moment, because he knew that Karasawa Criminal might have a solution.
And this is indeed the case.
I have to say that the other party's method is really powerful. He only made some preparations indirectly, and used the knowledge in psychology to control the other party's behavior pattern without his knowledge, and killed himself.
Not only that, even the remaining clues led the opponent to eliminate them on their own.
And the poison bottle also played a key role in this plan.
And now everything is clear.
Although I don’t know what lies Buta Hiroaki used to deceive the other party, he did let Iimori Zaaki take the poison bottle containing fugu poison and the apology note with the meaning of “suicide note” back home.
Coupled with the moldy black tea, the deceased directly cleaned up all the evidence.
To be honest, looking back at it, it even makes people feel creepy.
It was clear that Iimori was a person with independent consciousness early on, but all her actions on the night of her death seemed to have invisible threads behind her back controlling her actions like a puppet.
Moreover, the bottle clearly says "poison", which makes people subconsciously think that most people will not drink it unless they commit suicide.
To be honest, even Tang Ze had to admit that the other party's method this time was approaching perfection.
Under the guidance of the other party, Iimori Hayaki destroyed all the evidence, and the remaining evidence was indirect evidence that was not convincing.
No wonder Hiroaki Buta was confident and showed no fear when faced with Karasawa's suspicion.
Obviously, he had strong confidence in his own methods, and even felt that the case would eventually be ruled a suicide due to insufficient evidence.
But approaching perfection is not perfect after all. As long as it is a case committed by a person, there will be flaws. The only difference lies in the size of the flaws and whether the person looking for the flaws can find them.
Perhaps due to the guidance of fate, Hiroaki Buta unfortunately met Karasawa this time.
When he met this professor, Tangze already had a strong feeling that he would be a difficult opponent.
So when he went to Iimori Saki's apartment again, Karasawa was mentally prepared to get nothing, and made "100 million points" preparations with the help of [Xingshen Cigarettes].
With his current strength, the bonus given to him by [Awakening Cigarette] is much stronger than before. After all, his strength is much stronger now than before.
This "cheating" thing actually also pays attention to the basic method. It just allows you to perform extraordinarily based on the original foundation and will not exceed your original cognitive limit.
For example, if you master "addition", it is impossible for you to learn "multiplication" without a teacher. This is a cognitive limit.
But even so, it's enough.
Now Karasawa is no longer the second-rate detective who could only rely on plot tricks. With his current strength, even if it is just simple reasoning, he can be on par with Conan and Hattori Heiji, and even surpass him in some fields. .
So when [Xingshen Cigarette] was burning to the second half, Tangze was no longer just restoring the original appearance of the case.
He set the situation of the case into the worst possible scenario, and based on the currently known information and conditions, he deduced a method that could bring Hiroaki Buta to justice.
And next, it’s time to lay out.
………
In the small classroom, Hiroaki Buta looked through the students' homework and commented aloud from time to time.
He praised a lot, but also talked about his shortcomings in a humorous way, which often attracted laughter from the students, making this graduate seminar very happy.
Suddenly, there was a knock on the door, and everyone stopped smiling and headed towards the door.
"I'm sorry to interrupt everyone's class."
After knocking on the door, Karasawa, Takagi, Sato and others filed in.
"What's going on? Is there anything we can't talk about until after the seminar?" Hiroaki Buta looked at Karasawa and frowned and said dissatisfied: "Karasawa Criminal, I know you are eager to solve the case, but this is not your interruption. The students’ reasons for attending classes.”
"No, no, it's just because it's class, that's why we came here specially."
Karasawa smiled, called a boy from the door and explained to Hiroaki Buta: "This child is a resident of Iimori Saki's apartment and often plays football in front of the apartment.
So he saw the man who picks up Iimori Saki every day, and we came here this time to let the boy identify him."
When he saw the boy wearing a baseball cap, Hiroaki Buta's face suddenly turned ugly.
He looked at the timid boy in front of him, his eyes full of gloom.
He often sent Iimori Zaoji home, so he had naturally seen the boy playing in front of the apartment.
Every Tuesday and Thursday I send Hayaki Iimori back, and he can't guarantee whether he has been seen by the other party.
If he is identified by the child, even if he is confident that the other party cannot catch him, the affair will inevitably be exposed, his reputation and status will be destroyed, and his wife will divorce him.
Everything he killed to save would be shattered in this moment.
He admitted that he really started to get nervous at this moment.
But the will of reality did not change for him. He saw Tang Ze squatting in front of the boy and speaking loudly: "In name and reality, look to see if there is sister Zaoji's boyfriend here."
The boy seemed a little afraid of strangers. He did not speak but nodded heavily.
"Then can you just show us who it is?" Tang Ze touched the other person's head and said, "Don't be afraid. Once you recognize the other person, just point it out boldly."
The boy nodded again, and then began to look around at everyone in the classroom.
Although his little face was full of timidity, everyone saw his seriousness.
Everyone looked at the child, and for a moment the room fell into oppressive silence.
But Hiroaki Buta was even more so, and even his heart was raised unconsciously.
But when he looked at the boy, he still tried his best to show him a friendly smile.
After a while, the boy looked at everyone, and then watched Hiroaki Buta pointing his hand at the young boy beside him under the gaze of everyone.
The next moment, everyone present focused their attention on the other party, with surprise in their eyes.
Even Takagi, Sato Miwako and other criminals are no exception.
Because the name actually refers to not Hiroaki Buta as they expected, but Akio Ikedo who borrowed Iimori's early CD!
"Mingshi, are you sure it's him?" Seeing this unexpected situation, Takagi crouched down and looked at Mingshi and asked, "Is that right?"
"No...I saw him sending Sister Saki home several times." The boy nodded and said with certainty: "I definitely didn't admit my mistake!"
"But didn't you say he was an uncle?" Takagi said in astonishment.
"Uncle!" He pointed at Akio Iketo again and said in a real voice.
"Huh? Uncle?" Chido Akio pointed at himself, feeling that he had been seriously injured by a critical attack: "I'm only twenty-five years old!?"
Seeing this scene, Hiroaki Buta's heart suddenly dropped, and then he was ecstatic for the rest of his life.
But he did not forget that the crisis at this moment had not been relieved. The ecstasy in his heart only passed for a fleeting moment, and then he suppressed it.
"Angfu...you...are confused..."
Hiroaki Buta put on an expression of disbelief and looked at the student sitting next to him sadly: "Even if the relationship goes wrong, you shouldn't kill someone!"
"I didn't!" After hearing the professor's words, Ikedo Akio seemed to have realized the purpose of Karasawa and his party, and immediately said anxiously: "I am really not a prisoner!!"
"This...Karasawa Criminal..." Takagi looked like something unexpected had happened, and looked at Karasawa, who was frowning at the side, for advice.
"Take it back." Tang Ze didn't say anything more, he just gave the order with a stern face.
After hearing this, Takagi and Sato Miwako came to Ikedo Akio and urged Ikedo Akio, who kept shouting injustice, to go out.
Hiroaki Buta stood up and came to Karasawa and smiled. Just when he was about to say something, the other party didn't even say hello and turned around and left the classroom.
Hiroaki Buta didn't pay attention when he saw this. He told the students to study by themselves and followed Karasawa out of the classroom.
Walking out of the teaching building all the way, looking at Ikedo Akio being put into a police car by Takagi and Sato Miwako, Buta Hiroaki said with a sigh on his face: "I didn't expect it to be Ikedo..."
Speaking of this, Hiroaki Buta looked at Karasawa with concern, but his tone was full of playfulness: "It seems to be different from the prisoner you imagined Karasawa."
"What do you want to say?"
Karasawa had a sullen expression and did not look at Hiroaki Buta, but quietly looked at the police car that was gradually receding in front of him.
Seeing this, Buta Hiroaki didn't care. After all, who would care about the loser?
"The case is over. It seems that we will not meet again in the future." Hiroaki Buta waved to Karasawa with a pleasant smile: "Goodbye, Karasawa Criminal."
After saying that, Hiroaki Buta no longer cared about Karasawa's reaction and turned around and walked towards the teaching building.
After he turned around, the corners of his mouth began to rise, and eventually the smile became bigger and bigger. Although he didn't make a sound, it turned into an extremely wild one.
He knew that from now on there was no other way to bring him to justice.
He completed the "perfect crime" pursued by countless criminals!
This kind of pleasure of looking down and trampling on laws and rules gave rise to an indescribable pleasure in his heart, which spread throughout his body and made people tremble.
But he didn't see it.
After he turned around and left, Tang Ze was watching him quietly from behind.
Looking at Hiroaki Buta leaving with a proud expression, Karasawa shook his head slightly and turned to leave.
Under that calm face, a smile disappeared from the corner of his mouth in an instant.
