There were only two suspects in car No. 7, one of whom was Shohei Kono, an official of the Ministry of Foreign Affairs whom Hayashi had just met, and the other was a foreigner. When Lin Xiuyi came to the seventh car, the flight attendant in charge of serving the passengers in this car was explaining something in English to the emotional foreign passenger, but Lin Xiuyi could hear that the foreign passenger was not speaking English, but Spanish, which is very popular on the West Coast of the United States.

Lin Xiuyi stepped forward and showed his police account to the foreign passenger, and after the other party saw Lin Xiuyi's certificate, he was stunned for a moment, and then became even more emotional. Although Lin Xiuyi's English has improved in the United States, he doesn't know anything about Spanish, but he can tell whether the other party is speaking Spanish or not.

Maybe it was Lin Xiuyi's behavior that angered the other party, the other party stretched out his hand and was about to push Lin Xiuyi, but fortunately he was stopped by the flight attendant in time, and Lin Xiuyi was also stunned. If you can't even do basic communication, then how can you ask the other party about the case? In the midst of this chaos, Shohei Kono's voice suddenly came from in the distance.

"Lin Police Department, it seems that there is some trouble!" Kono Shohei stood by the door of his box, one foot had already stepped out of the box, he tidied up the suit on his body, and then picked up a round badge from his pocket with two fingers, took it to his mouth and blew it proudly, and then put it on the left chest of his suit. Although it was far away, Lin Xiuyi could see it clearly, it was a coat of arms of the Ministry of Foreign Affairs, and the pattern on it was a deformation of the Chinese character "outside".

"Do you need help from my colleagues in the Ministry of Foreign Affairs?" said Kono Shohei, standing in the distance, slightly smug to Hayashi Shuichi.

"Okay, but don't forget, you're also one of the suspects! Wouldn't it be better to clear your suspicions first?" Lin Xiuyi replied unceremoniously.

"Xiu Yijun, this gentleman speaks Spanish, and he happens to know a little Spanish. Of course, my assistance is not unconditional, first of all, you have to clear my suspicion before the train arrives, and secondly, I have always been curious about how the search lesson works, so if I can, I would like to follow you to find out how you work......"

Kono Shohei said half-jokingly that although Lin Xiuyi has always been unpretentious to him since the case, Kono Shohei has some admiration for Lin Xiuyi from the bottom of his heart, after all, it is really rare for a police officer who is willing to offend his colleagues in the Ministry of Foreign Affairs to enforce the law impartially!

After a little thought, Lin Xiu agreed to Kono Shohei's conditions. In fact, he felt that Kono Shohei's proposal to clear the suspicion was not a condition at all, and it was the job of the police to find out the real murderer from among the suspects, as long as the real murderer who killed Erika Shiraishi was found, the suspicion of the other suspects would naturally be cleared. As for the second point raised by Kono Shohei, Lin Xiuyi felt that it was not a problem, if Kono Shohei followed Lin Xiuyi, it would be convenient for Lin Xiuyi to take monitoring measures against Kono Shohei. Therefore, Lin Xiuyi had no reason to refuse Kono's proposal that was beneficial to the investigation.

Lin Xiu looked at Kono, and then nodded to express his willingness to accept Kono's plan, but he quickly opened his mouth to explain to Kono: "It's okay to follow me, but you can't have any language contact with other suspects, and you can't be present when I ask other suspects about their testimony......"

"No problem, as long as you don't trap me in the box," Kono said, and then he couldn't wait to walk over to Lin Xiuyi, he stood in front of the foreign passengers, smiled at the other party, and then said to the other party in Spanish: "Hola!"

"Wait a minute!" Just when Kono was about to continue communicating, Lin Xiuyi suddenly stopped him, he turned on his phone, clicked on the app on his phone that can record audio, and then continued to Kono: "Now you can continue!"

"What do you mean by that!" Kono asked, slightly dissatisfied.

"To prevent collusion, hurry up! First ask him what he was doing from 11 o'clock last night to 1 o'clock in the morning!"

Kono Shohei translated to the other party according to Lin Xiuyi's meaning, and the other party heard that Kono could communicate in Spanish, and his vigilant expression immediately relaxed, and then Kono and the other party didn't know what to talk about, and the more they chatted, the more lively they became.

The reason why Lin Shuichi wanted to record it was to prove that Kono and the other party did not collude, and this recording could be handed over to the police in Aomori City for further analysis after the train arrived at the station, so as to determine the content of the conversation between Kono and the other party. However, as soon as Lin Xiu saw Kono and the other party chatting for a long time, he and the train attendant couldn't understand anything, so he couldn't help but be a little anxious, so he pulled Kono's sleeve.

"Don't you forget to get down to business, tell me what the other party said?" Lin Xiu reminded Kono.

"This gentleman, Miguel Alemán Valdés, is a photographer from Mexico, and he said that during the time you described, he was busy with his work in the box......" Kono Xiang smoothly translated every word that Mr. Valdés said to Lin Xiuyi, and in the process of his translation, Valdés kept adding something, and Kono actually translated it all without pause, which made Lin Xiuyi feel sincere admiration, the other party here and there is a little bit of Spanish, and it is completely the level of simultaneous translation!

"He said he was working, is there anything to prove?" Lin Xiuyi asked curiously.

"He said the picture is in his camera right now, and he can show it to you if you need it......" Kono Shohei translated to Lin Shuichi again after communicating with the other party.

Of course, Lin Xiuyi wanted to see it, and Kono immediately conveyed Lin Xiuyi's meaning to this Mr. Valdés, and Lin Xiuyi and others were immediately let into Valdés's box, under Valdés' operation, a precious Nikon camera was handed over to Lin Xiuyi, and on the display screen of the camera, Lin Xiuyi saw Valdés's photographic works, which were the scenery outside the car window under the moonlight, which looked like a quiet and lonely beauty, which was indeed not taken by ordinary people.

With these photos, as long as the train arrives at the station, it is only necessary to compare the time on these photos with the exact death of the deceased to determine whether Valdés is suspicious. Because these photos themselves have time and are not taken from the same angle, it can be concluded that they were not taken using the camera's timing function. As for whether the camera's time is fake, it can also be proved with the help of the speed and position of the train. In general, if the time on Valdés' photograph covers the time of the crime, then Valdés has a sufficient alibi.
