Ishibashi hopes that Lin Shuichi can solve the case as soon as possible, so that the impact of the incident can be minimized. Lin Xiuyi did not agree to the other party's request, but asked about Shiqiao's alibi from eleven o'clock last night to one o'clock in the morning.

"What, even I have to be the object of suspicion?" When Shiqiao was interrogated by Lin Xiuyi, he asked Lin Xiuyi very angrily.

"I asked the same question to everyone, not on purpose to target a particular person, I hope you understand, Mr. Ishibashi!" Lin Xiuyi said with the same attitude.

"Shuichi-kun didn't target you, just asked as usual, Mr. Ishibashi, please don't mind! Besides, if you can provide alibi evidence, you won't have to worry about the Aomori Prefectural Police when the train arrives in Aomori. Kono Xiangping, who was sitting next to Lin Xiuyi, saw that the atmosphere between the two was a little stiff, and hurriedly came out to play a round and said.

The atmosphere in the carriage froze for about ten minutes before Ishibashi replied, "I've been here since dinner, and the waiter at the door can testify to this." ”

Since the other party presented his alibi, Lin Xiuyi naturally wanted to verify with the relevant parties. So after asking some other questions, Lin Xiuyi left the No. 9 car, called the service staff in the No. 9 car to the side alone, and asked Ishibashi Heizo's alibi again. After Lin Xiuyi's patient and careful questioning, there was no major discrepancy between the testimony given by the flight attendant and the description of Ishibashi Heizo, and from this point of view, the testimony was very credible.

"How is it, do you have a clue now?" When Lin Xiuyi returned to the No. 8 carriage again, Kono Shohei asked Lin Xiuyi curiously.

Lin Xiuyi did not answer Kono's question, he returned to his box alone, blocked Kono out of the door, and then called the flight attendant to bring a cup of black coffee to his box. Lin Xiuyi, who had not slept all night, was really tired now, he walked into the bathroom and sobered up with cold water, and by the time he left the bathroom, the black coffee had already been delivered to the door of his box.

Lin Xiuyi came to the tea room on the second floor with coffee, he sat in front of the coffee table, picked up the coffee cup and drank two sips of bitter coffee, when he felt the unique sweetness and aroma of coffee between his lips and teeth, Lin Xiuyi's spirit was reinvigorated. He flipped through his notebook and began to reorganize the night's harvest.

From the current point of view, there are a total of 8 suspects on this train who have the ability to kill Erika Shiraishi, among which Sakurako Takudai, Yasuyuki Minamida, and Haruko Kakiya in car 6 are the most suspicious. The foreign passengers Valdés and Shohei Kono, who were in car No. 7, still could not rule out suspicion because of the lack of alibi. As for Mr. Yasuo Hashimoto in the No. 8 car, it seems that he has suicidal tendencies, but what his motive for suicide is Lin Shuichi is unknown, and he has already instructed the crew on the train to always pay attention to Mr. Hashimoto's every move, and contact him immediately if there is any strange behavior. The last remaining Mr. Heizo Ishibashi in car 9 was himself a senior JR EAST executive, so the alibi provided by the conductor could only be accepted with some reservations.

Almost all of the suspects have some degree of problematic problems, and there is a great deal of uncertainty in the testimony provided by each of them. And the time left for Lin Xiuyi seems to be running out.

What to do, do you investigate them all, time does not allow it, and it is impossible. Lin Xiuyi could only selectively carry out the next step of the investigation. Since this is the case, then the No. 6 carriage, which is the most suspicious, is naturally the focus of Lin Xiuyi's attention.

According to past experience, the first person found at the scene, Sakurako, was the most suspicious, so Lin Xiuyi still had to continue the investigation from Sakurako's body. Lin Xiuyi carefully read the interrogation notes of the three suspects in the No. 6 carriage in the tea room. And re-recalled the plot of meeting these suspects, and the more I thought about it, the more I felt that the suspects in car No. 6 were very suspicious. Except for the old lady Kakiya who was paralyzed in bed, and the youngest daughter of the Kakiya family, the remaining suspects have the ability to kill Erika Shiraishi. And Erika Shiraishi, who had a close relationship with her during her lifetime, Sakurako and Yasuyuki Minamida, are naturally more suspicious.

After drinking a cup of coffee completely, Lin Xiuyi stood up again, put on his coat, came to the No. 6 box again, and knocked on the door of Sakurako's house.

"That one" came from the voice of Sakurako Takurii in the box.

"Hello, Ms. Takujui, I'm Lin Shuichi from the Search Lesson, when I was in the lounge just now, because you were frightened, so our questioning is not over yet, I don't know if I can delay you a little longer, I want to ask you about the situation when you found the body......" Lin Shuichi stood outside the door and explained to the suspect Sakurako Takurii.

"Well, I've already fallen asleep, can't I be tomorrow?" Sakurako Takuri quietly walked to the sliding door, trying not to make any noise, and at this moment, the huge golf bag she had brought with her on the train stood at the head of the bed, and the bag had been opened, revealing a full bill inside.

"If that's the case, then you can only be questioned by the Aomori County Police after the train arrives in Aomori......" Lin Xiuyi said with some disappointment, he stood at the door and waited for a while, but did not hear any response, so he reluctantly turned around and walked back, just walked a few steps, but suddenly heard the sound of the sliding door being opened behind him. As soon as Lin Xiu looked back, Sakura actually opened the sliding door and leaned out.

"Officer, you better come in!" Sakurako saw Lin Xiuyi at a glance and immediately greeted Lin Xiuyi.

"Which? won't this bother you?" Lin Xiuyi asked suspiciously, he had obviously been rejected just now, why did Sakurako change her mind again?

What Lin Shuyi didn't know was that Sakurako Takuri was more afraid of the Aomori Prefectural Police than him, and if she was detained by the Aomori Prefectural Police and couldn't leave the country, she wouldn't be able to fly to South Korea smoothly. And Sakurako Takudai still has 100 million yen in cash hidden on him, although this money is legal income, but if the police continue to investigate because of the suspicion, maybe his apartment in Ginza, as well as the body and pistol hidden under the apartment, will be found. For Sakurako, Lin Xiuyi, a young policeman who looks like a rookie, is much easier to deal with than the Aomori County police, the lesser of two evils, Sakurako is naturally more willing to try her luck from Lin Xiuyi, Ginza's mother San, has always been good at deceiving men, even if the other party is a policeman!

Sakurako smiled at Lin Xiu, and then pretended to be embarrassed and said, "I'm sorry officer, I was taking a bath just now, so I didn't open the door for you immediately, or you should come in and talk about it!"
