Chapter 223 Questioning the Soul
The sodium hydroxide solution does burn your throat.
But that also depends on the concentration.
The concentration is low, let alone being used to poison people.
Let's put it this way, the kind of human lubricant used in certain sensitive parts contains sodium hydroxide to thicken and lubricate it.
This ultra-low concentration sodium hydroxide solution is completely non-dangerous and cannot burn human mucous membranes. Otherwise, that picture would
And under Lin Xinyi’s in-depth and simple explanation,
You don’t need to have studied junior high school chemistry or elementary school mathematics. All the guests here will know how unreliable this trick used to create an alibi is.
"That is to say." Everyone responded.
Especially Matsumoto, who looked at his son-in-law with a sharp look:
"The dissolution time of the capsule doesn't mean anything at all, and Takasugi's alibi is completely invalid?"
"That's right."
Lin Xin nodded and added:
"If I guess correctly, the murderer must have put the half-dissolved capsule into the can of lemon tea together with a large amount of sodium hydroxide."
"According to his thinking, when we see the capsule, we will subconsciously think that he is poisoning with capsule-type sodium hydroxide."
"This method can theoretically play a certain role, but"
Speaking of this, Lin Xinyi himself felt a little sad.
He had just been thinking about it for ten minutes, but he didn't even think about why the murderer put such a capsule in the lemon tea.
The result was unexpected, really unexpected.
The murderer put such a capsule in because he was stupid.
"If you want to use capsules to confuse the public and mislead the investigation, you should put more capsules in!"
"There is only one capsule, and this little bit of sodium hydroxide, is it used to treat hyperacidity?"
Hearing this mocking exclamation, the groom's face, Toshihiko Takasugi, turned red and white.
Not only does it look guilty, but it's also extremely funny.
"Mr. Takasugi, you said you came to the dressing room three minutes before the incident, right?" Lin Xinyi asked calmly.
"Yeah" Takasugi Toshihiko nodded stiffly.
"That's right."
Lin Xinyi's eyes suddenly became sharp:
"When Miss Maori and I rushed over to investigate, the jar of lemon tea was still hot!"
"And when I saw Miss Sayuri drinking lemon tea before, she drank it clearly cold."
"Her lemon tea was obviously warm because the murderer added too much sodium hydroxide. The sodium hydroxide dissolved in water and gave off a lot of heat, so it became lukewarm!"
"And this warm lemon tea didn't even have time to cool down before Ms. Sayuri collapsed in shock."
"This shows that the murderer poisoned her just minutes before she drank the poisonous drink."
"Mr. Takasugi Toshihiko——"
"As you were in the dressing room just three minutes before the incident, you are undoubtedly the biggest suspect in this case."
"I, I." Takasugi Toshihiko became a little incoherent.
He was no longer as calm as before, and panic was written on his face.
At this time, Matsumoto's vigilant expression turned extremely ugly.
No matter how much he didn't want to believe it, seeing his son-in-law looking so guilty and helpless, as an experienced veteran policeman, he could guess who the murderer was.
"Why did you kill Sayuri?"
"She obviously loves you so much, bastard!!"
Matsumoto's vigilant body was shaking violently, and his voice was full of pain.
Hearing Sayuri's name, Takasugi Toshihiko instinctively showed a guilty look.
However, after seeing the fierce face of my father-in-law,
But he gradually stabilized his aura, stood there majestically, and showed a cold smile:
"Hey, father-in-law, and this Mr. Lin Xinyi."
"You two are both management officers of the Metropolitan Police Department."
"As managers, don't you know that you should speak with evidence?"
"I am indeed the most suspicious now, but do you have any evidence to prove that I was the one who poisoned you?"
Takasugi Toshihiko simply stopped pretending.
Not only did he no longer pretend to be a good guy, he even showed a smile of joy without restraint.
This kind of resentful emotion was not directed at Lin Xinyi, who exposed his ignorant tricks, but toward the man who had believed in him until just now, his father-in-law Matsumoto.
It was as if he had some kind of blood feud with Police Matsumoto.
"Takasugi, you."
Matsumoto Jingjing instinctively wanted to get angry, but he no longer had the energy to do so.
He never expected that the man his daughter loved would actually be such a cruel and heartless monster.
"Why?"
Matsumoto had been holding back the traces for a long time, but he could only find out why.
But Takasugi Toshihiko snorted coldly and replied ruthlessly: "Why?"
"I told you I'm not a murderer. Don't accuse good people unjustly."
"Don't talk nonsense without evidence. Otherwise, I will ask a lawyer to sue you for insult and defamation from the Metropolitan Police Department."
"This is bad." Lin Xinyi's eyes narrowed:
Only then did he remember that Mr. Toshihiko Takasugi was also a Celestial Dragon.
Ordinary people can rely on the combination of evidence and interrogation to break through their psychological defenses, but such a big shot will never cooperate with the interrogation honestly.
Not only were they not afraid when they were invited to drink tea at the Metropolitan Police Department, they could also say leisurely: "No comment, I want to wait for my lawyer to come over."
Therefore, if you want to send a wealthy man with a team of lawyers to jail, the evidence chain must be complete and impeccable.
But how easy is this?
"There was no surveillance at the scene, no video recording."
"And if this bastard dares to say such things, the fingerprints on the medicine bottle should have been wiped clean by him."
"As for the drink bottle, even if it has his fingerprints on it, he can still find an excuse to say that he took it when he came in to see Sayuri."
"The poisoner could have come in after he left, a murderer who may not even exist."
"Similarly, even if his footprints, hair, and dander are left at the scene, none of them can prove that he poisoned and killed people."
"Then we can only hope for further testing."
"If there is any skin flakes that are difficult to detect with the naked eye on the plastic pill bottle, we might still have hope of sending him to jail."
Thinking of this, Lin Xinyi couldn't help but have a headache.
He has done his best, and now he can only gamble on luck.
If hard-core evidence that even the lawyers cannot find can be found, Mr. Takasugi Toshihiko will basically be acquitted.
Lin Xinyi thought so in his heart.
At this time, Mao Lilan suddenly stood up with some emotion:
"When Mr. Lin dissolves sodium hydroxide in water, there should be a lot of movement, right?"
"It's pretty big." Lin Xinyi recalled his junior high school chemistry experiment: "There will be a lot of small bubbles coming out, and a lot of heat will be released."
"If you put too much, it might look like water boiling."
"So. What's the problem?"
He stared at Mao Lilan curiously, wanting to ask her if she had discovered anything.
But Mao Lilan shook his head:
"I didn't find anything, just"
"Mr. Sayuri, maybe she really loves Mr. Takasugi."
"So...she knew the lemon tea was poisoned, but she still drank the drink."
"Huh?" Everyone was slightly startled, and Takasugi Toshihiko even trembled.
"What did you say?"
The resentment on Takasugi Toshihiko's face turned into shock:
"Sayuri knows. Does she know that the murderer poisoned her?"
"Yes." Mao Lilan sighed deeply.
She looked at Toshihiko Takasugi quietly, her eyes extremely complex:
"I know that when Mrs. Sayuri drinks lemon tea, she always takes small sips and savors it carefully."
"Because she said that this way she can slowly relive the taste of her first love in childhood."
"If that's the case, then she could tell something was wrong when she took a small sip, so how could she be burned so badly?"
"Especially when sodium hydroxide dissolves in water and bubbles up and generates a lot of heat."
"With such an obvious change, would she really not notice it when she gently sipped the hot lemon tea?"
Mao Lilan paused slightly, and her tone became deeper:
"So, I think Sayuri-sensei should already know."
"She knew her husband was poisoning her and the man she loved most wanted her dead."
"So she was desperate. She drank the poison cast by her lover and wanted to die as she pleased."
"Mr. Takasugi."
Looking at Takasugi Toshihiko who was already shaken, Mao Lilan's eyes quietly filled with a soft light.
This light is so pure, with a power that seems to cleanse the soul.
In such a seemingly innocent way, she tortured Takasugi Toshihiko's heart:
"Don't you feel sad at all?"
"Teacher Sayuri, isn't it the person you love?"
"I, I" Takasugi Toshihiko's face turned pale again.
But this time the paleness was not the panic caused by the trick being exposed.
It is a kind of pain and bitterness that comes from the heart and originates from pure emotions.
"I thought, while holding that warm cup of lemon tea."
"Sayuri-sensei must have a very cold heart."
Mao Lilan sighed sadly:
"She obviously loves you so much and is even willing to do anything for you!"
"What are you talking about!"
Takasugi Toshihiko covered his ears, as if he couldn't bear to listen any more:
"These are all your conjectures. I am not the murderer at all."
"Besides, no one would drink poison by themselves!"
He warned himself deeply not to think about it.
But Sayuri's poignant appearance of taking the poison in despair still lingered in his heart like a lingering nightmare.
"Sayuri will do it!"
Suddenly, another voice sounded from the crowd.
The speaker was none other than Sayuri Matsumoto’s college classmate and best friend:
"No one else would do something so stupid, but Sayuri would."
"Because...she is such an idiot!"
"Takasugi Toshihiko, do you know:"
The best friend spoke up for Sayuri angrily:
"Sayuri, she knew your purpose of approaching her from the beginning."
"He knows your true identity and the grudge between you and her father."
"But she still fell in love with you. She thinks you are a good person and she is willing to stay with you for the rest of her life -"
"But, Takasugi Toshihiko, what did you do to her?!"
"W-what."
Takasugi Toshihiko fell into a state of stupidity:
"Sayuri, does she even know those things?!"
This was like the straw that broke the camel's back, completely breaking the murderer's psychological defenses.
"how so."
"Then, what did I do?!"
Faced with this shocking fact, there is also Mao Lilan's pure eyes that seem to touch the soul.
Takasugi Toshihiko completely gave up resistance.
