Chapter 5 Section five

"Are you serious?" "real." How could anyone joke about such a thing. "Tatsu was also killed." "But……" Yoko thought for a while, then licked her lips with her tongue, "How did you kill him?" "Use light." "Light?" "That's right. Shining a bright light on Hana Tatsuya's eyes made him lose his balance and fall from the roof." "……I see." Yoko glanced around the room.This is the tailoring room for home economics classes. "Is that why you asked me to come here?" "That's right."

I connected the location of the flash that Hiromi and the others saw with the location where Tatsuya fell from the building with a straight line, which would then extend to the window of the tailoring room, and drew it on the blackboard next to me to illustrate. "But, is there anything in this room that can emit such a strong light?" "Have." Saying that, I went to the window and pulled open the white curtains abruptly.The dazzling sunshine of May suddenly shot into the room at an acute angle. "That day was the same as today, and the weather was fine. In this way, the murderer can take advantage of the dazzling sunlight."

"Mirror……" "That's right, just use that thing." I dragged the full-length mirror beside me.When I was last in this room, I never dreamed that this thing could be the key to everything. I adjusted the angle of the full-length mirror to reflect the sunlight onto the roof of the opposite school building.At the stairway on the top of the building, the rectangular light and shadow of the full-length mirror suddenly appeared. "Is that the light that Ada saw at that time?" Yoko walked up to me, looked at the light and shadow on the wall at the stairs and said.

"However... can this matter go so smoothly? Even if the reflection can dazzle his eyes, he might not be able to step on the ground?" The probability is either one in ten or one percent, but far less than fifty percent. "So I think the murderer didn't intend to kill him. It's better than a simple prank, with a little bit of malice. I guess he just wanted to scare him." "mischief……" "Of course, I can't just let the murderer go. Human life is at stake. No matter what, I will get the murderer out." "Do you have any clues?" "It's okay, I have my own opinion. Yoko, you don't have to worry about it."

She stared at my face for a while, then turned away and murmured. "Okay, then please. If you find out who the murderer is, you must be the first to tell me." I replied "Understood".Put the full-length mirror back in place.The light and shadow projected on the wall at the stairway before instantly melted into the blue sky. The murderer might have stumbled into this tailoring room at the time—that was the basis of all my thoughts.It was unlikely that he had come to the tailoring room on purpose as a prank.The idea of ​​using a full-length mirror to reflect sunlight is probably a temporary idea.

In this way, who was in the tailoring room after school that day became the crux of the matter.This must first be cleared up. "The classes that were taught here that day were Classes 7 and 8 of the second year of high school." Faced with my unreasonable question, Kato-sensei did not show the slightest displeasure.Maybe he knew very well that I was investigating that matter.Although Tatsuya's death was ultimately dismissed as an accident, many people were interested in it because it left so many mysteries. "The sixth class that day was for Classes 7 and 8, but it is said that those who failed to complete the project in class still stayed in the tailoring room after school. However, when the accident happened, there were already There is no one left."

"Who is the last one left?" "That's not clear... Ah, you came just in time." Teacher Kato stopped a girl passing by us.The girl was the vice-president of Class 7, Grade 2, and her name was Reiko Kijima.With short hair and dark skin, it gives people a lively feeling. The teacher asked her the question I wanted to ask, but she couldn't answer clearly. "Is there any connection between this and the accident?" Seeing that I was a little disappointed, Reiko Kijima asked.I nodded slightly, "But it's not clear right now." Her expression was slightly hesitant.

"Or, I'll check it out for you." "Can you check for me? I'm sorry to trouble you." "It's all right. I'd love to." Reiko Kijima's eyes lit up, and she listed three criminal police TV dramas that she watched every episode.Although I haven't watched the films she mentioned, I immediately echoed a few words and accepted her assistance. That night, she told me some news. "The last ones don't seem to be from Class Seven. According to this, they should be from Class Eight." "Really? Then I'll ask the people in Class Eight."

"I'll go and investigate for you." "When you are not from Class Eight?" "It's okay. If the information I provided helps you find some clues, you should tell me." Although it felt a little awkward, Reiko Kijima's assistance was really helpful, and in the end I had to say "I will" to get away with it. "Then just wait for my good news." Reiko Kijima seems to be in high spirits. Two days later, I heard about Miyoko Kasai's suicide attempt.She took a lot of sleeping pills, but failed to reach the fatal dose, so she saved her life.It was the female director of the football department who told me the news, because she had friends in the second and eighth classes of high school, so she learned the news.

"Only a small number of people know about her attempted suicide. So senior, don't spread it to others." The supervisor told me to keep it a secret, but she ran to tell others about it herself. At night, Reiko Kijima called again, and her excited voice came from the receiver. "I found out that Kasai-san was the last one left in the tailoring room that day. But I haven't checked with her face to face. She asked for leave today..."
