After she became the daughter of a vicious warlord, she cleaned herself up

Chapter 248: Poisoning Suspect

Although Takahashi Yui looks calm on the surface, he must be full of doubts and vigilance on the inside.

After all, a living person died unexpectedly right under his nose, and anyone would be worried about this.

The two returned to the office and Takahashi Yui sat at his desk.

His fingers tapped lightly on the table, making a "tapping" sound that was particularly clear in the silent room.

Jiang Shiyuan stood aside, waiting quietly.

After a long while, Takahashi Yui slowly spoke: "Ayako, who do you think did this?"

Jiang Shiyuan pretended to be in deep thought and thought for a while before answering.

"Yuyi, this...I can't really say."

"However, this prisoner holds important information about the underground party. Could it be that... someone wants to kill him to silence him?"

Takahashi Yui frowned slightly, said nothing, and seemed to be thinking about something.

Seeing this, Jiang Shiyuan continued, "Youyi, I want to... help you investigate this matter."

Takahashi Youi raised his head and looked at Jiang Shiyuan deeply, his eyes full of scrutiny and inquiry.

Jiang Shiyuan looked at him fearlessly with a frank gaze.

"Okay." Takahashi Yui finally spoke, "Since you are willing, let's investigate together, but..."

He changed the subject and said, "Don't make this matter public for the time being, so as not to alert the enemy."

"I understand." Jiang Shiyuan nodded, secretly happy.

This is exactly the opportunity she wants!

Only by participating in the investigation can she better take the initiative, clear herself of suspicion, and at the same time continue her plan more conveniently.

In the next few days, Jiang Shiyuan actively cooperated with Takahashi Yui's investigation on the surface, but secretly he was quietly carrying out his own arrangements.

She used her identity as a confidential secretary to review a large amount of information, trying to find some clues.

Soon, the test results came out.

"Glycoside plant toxins" were detected in the deceased's blood, and there were also toxin residues in the skin and flesh tissues at various parts of the wound.

The report lists several plants that may contain this type of toxin, including oleander, lily of the valley, and poison arrow tree.

"Glycoside plant toxins..." Takahashi Yui looked at the test report with a frown.

"It seems that the murderer used some kind of plant to poison the prisoner."

"That basin of water!" Jiang Shiyuan's eyes suddenly lit up, "Youyi, do you still remember the basin of water in the interrogation room?"

"According to what you said before, the prisoner began to show symptoms of poisoning after being awakened by the cold water."

"There are also toxins left on the wound skin and flesh. The poison... must have been put in the basin of water."

Takahashi Yui nodded, "I thought so too. I have asked someone to test the basin, and I believe there will be results soon."

Sure enough, not long after, "glycoside plant toxins" were detected at the bottom of the pot, and the concentration was not low.

"It seems that the murderer used that basin of water to poison the prisoner."

Takahashi Yui pushed up his gold-rimmed glasses and asked in confusion, "But who is the murderer?"

"Besides me and the criminal, the only people in the interrogation room at that time were Yusuke Yamaguchi and you."

Jiang Shiyuan's heart tightened, and Takahashi Youi began to suspect them.

She pretended to be calm and said, "Youyi, are you doubting... me and Director Yamaguchi?"

Takahashi Yui did not answer directly, but asked: "Ayako, what do you think?"

Jiang Shiyuan took a deep breath and calmed himself down.

This is a critical moment and she must not reveal any flaws.

"Youyi, you know, I used to be a doctor, and saving lives is my duty."

"How could I possibly do such a thing?"

"Besides, I have no reason to do this!"

"Then how do you explain the plant toxins in that basin of water?" Takahashi Yui pressed on.

"This..." Jiang Shiyuan pretended to be flustered, "I...I don't know either!"

"Although there were only the prisoner and the three of us in the interrogation room at the time, many people had the opportunity to come into contact with the basin of water before we entered."

"For example, the person who is responsible for guarding the prisoners, the person who is responsible for cleaning up the interrogation room, the person who is responsible for fetching water..."

"Besides, I was only a few steps away from the torture table. How could I have poisoned him in public?"

Takahashi Yui was silent, as if thinking about Jiang Shiyuan's words.

Seeing this, Jiang Shiyuan continued, "Youyi, if you really doubt me, I am willing to accept any investigation."

"I can assure you with my professional ethics and professional qualities, as well as my loyalty to the Great Japanese Empire, that I have never done such a thing!"

"What about Yamaguchi Yusuke?" Takahashi Yui suddenly asked.

"Director Yamaguchi?" Jiang Shiyuan pretended to be surprised. "He...he is even more impossible, right?"

"He is the director of the operations department of Section 1. It is his duty to arrest and interrogate underground party members."

"If he wanted to do it, he would have done it long ago. Why wait until now?"

Takahashi Yui fell silent again, Jiang Shiyuan's defense seemed impeccable, and Yamaguchi Yusuke had no motive for committing the crime.

But who else could it be besides them?

"Youyi, we should now trace the source and find out who else has touched the basin of cold water that was poured on the dead man."

Jiang Shiyuan thought for a moment and said, "The poisoner must be a Red Party undercover who wants to kill and silence the witness."

"Or maybe he happened to have some personal grudge against the deceased and wanted to take revenge."

Takahashi Yui's eyes lit up, as if he had thought of something.

"You mean... there's a traitor in our Special High Section stationed in Shanghai?"

"I'm not sure, but it's not impossible."

"After all, the arrest of this underground party member has far-reaching implications, so it's inevitable that the Red Party will take risks."

Takahashi Yui nodded, "What you said makes sense. Next, we have to find out the hidden traitor!"

"Section Chief Takahashi is wise!" Jiang Shiyuan flattered him at the right time.

"I believe that under your leadership, our Shanghai-based Special High Section will be able to find out the truth, catch the traitor, and achieve great results!"

Takahashi Yui smiled helplessly, "Why are you calling me Section Chief Takahashi again in private? Do you want your salary to be deducted?"

"Ah, no!" Jiang Shiyuan immediately made a sad face and acted as if he was heartbroken.

Takahashi Yui patted her shoulder and said with a smile: "Okay, I won't tease you anymore."

"Ayako, please take some time off and help me investigate this matter."

"Report to me immediately if you find anything."

Jiang Shiyuan patted his chest and assured: "No problem, Youyi, I will do my best to assist you!"

After Jiang Shiyuan left, a man in a black suit walked into Takahashi Yui's office and asked respectfully, "Section Chief Takahashi, are you looking for me?"

"Yes." Takahashi Yui nodded. "For the next few days, help me keep an eye on Secretary Sakai and see what she has been doing and who she has been meeting with."

"Hi!" the man responded and turned and left.

Takahashi Yui looked at the man's departing back, and a complicated look flashed in his eyes.

He didn't know if his decision was right, but he had to do it.

Because he can't let go of any suspicious person, even...his beloved woman.

As night falls, the lights are on.

When Jiang Shiyuan was driving home, she spotted a black car secretly following her.

It seems that Takahashi Yui is still skeptical of her.

Jiang Shiyuan realized that he had to clear himself of suspicion as soon as possible, otherwise he would be exposed sooner or later.

But what should she do?
