Chapter 40 Section VI

The train Yabe was on continued to travel north, and the monotonous sound of the train continued to drill into the eardrums. Yabe leaned his head on the back of the chair and thought about Egami Fuutarou. Egami Fuutarou must have also taken this train to Sendai five nights ago, and was convinced that Iseki Kazuhiko killed the Tajima couple. On what basis did he believe that Iseki killed the Tajimas?This question once again surfaced in Yabe's heart. After reading the diary of Tajima Mariko, Egami Fuutarou said that he was more convinced that it was a murder. Since Yabe read the diary several times, he could almost recite it. It was a homicide incident. Looking at it as a whole, he only came to the conclusion that it was forced to die for love. However, looking at it in parts, it was indeed suspicious.

For example, this incident started when Mariko Tajima knew that her husband was having an affair. The reason why Mariko knew that her husband was having an affair was because someone wrote an anonymous letter to tell her, but she didn't know who that person was. She also only said in the diary that it seemed to be a woman's handwriting. Maybe she was so full of her husband's affair that she didn't notice who wrote the anonymous letter to her?However, Yabe did not think that Fuutarou Egami was convinced that it was a murder based on this incident. Mariko Tajima witnessed her husband enter the Kokubo Pharmacy, which also makes people feel that it is too coincidental. Could someone have deliberately arranged that?During the search, this point was also included in the focus of the investigation, but it was not found out that it was deliberately arranged.

Although Mariko Tajima suspects that her husband obtained potassium cyanate from the Kokubo Pharmacy, since there is no evidence to prove it, her doubts are still doubts and cannot be taken seriously. Thinking about it this way, Yabe could not understand the sentence that Egami Fuutarou said, "I am sure from the diary that it was a murder."If it was a murder, Kazuhiko Iseki was the murderer, and if Iseki was the murderer, there should be strange actions by Iseki in Mariko Tajima's diary!Be careful with such records about Iseki, but after looking through the entire diary, you can only trust the records of Iseki. Therefore, on what grounds does Egami believe that Iseki is the murderer of the Tajimas?

Yabe stared at the night scene outside the car window, which might make him feel better, and maybe he accidentally discovered the negligence. It was nearly twelve o'clock, and the train Yabe was on would arrive at Tsuchiura soon because he was traveling on the Tokiwa Line. Looking carefully out of the train window, he could see the gray surface of the lake glowing in the night. "Maybe Fuutarou Egami also saw the surface of the lake?" Yabe closed his eyes, thinking of Fuutarou Egami's round face full of kindness, "Is he dead already?"
