Chapter 61 Section VII

Dr. Yajima spoke when the topic of arresting the murder of Iwamura came to an end. "The narration of the two just now made the process of the two murders clear, and the murderer should be true. But in this way, what does the murder of my father ten years ago mean? To be honest, I secretly hope that the murderer who committed the murder this time is the murderer who killed my father ten years ago. I hope that when the truth of this murder is revealed, the murderer who killed my father ten years ago will also be found out, but the truth does not seem to be the case .Mr. Interpol also thinks that Shinichi is not the real murderer of the murder case ten years ago, right? "

"Yes, not Shinichi. In the end, who designed and manufactured the double-structured greenhouse? Did Shinichi order it for this murder case? No, not really. Because the skeleton of the semi-conical greenhouse was never It was stored in the depths of the farmhouse a long time ago. Those devices must have been made ten years ago, with the purpose of killing Dr. Yajima’s father, Mr. Yajima Yoichiro, as for the maker…” The Shachuan Police Department calmly said the person's name. "I think it's Toyozo-san." "Ah!" Changdai let out a weak sigh. "As expected...as expected."

"That's the only way to determine it. In other words, Toyozo-san committed murder ten years ago with this double greenhouse, and Shinichi just adapted his father's method this time." The Shachuan Police Department began to describe the murder case ten years ago. "The process of Mr. Toyozo killing Mr. Yoichiro Yajima is much simpler than this murder case. First, Mr. Toyozo set up a semi-conical greenhouse in the greenhouse, and then killed Mr. Yajima Yoichiro near the false exit of the semi-conical greenhouse.From the perspective of the semi-conical greenhouse, the location of the murder was outside the exit, and from the perspective of the outer greenhouse, it was approximately in the center.Again, just use witnesses in moderation.The most suitable witness at that time was the wife of Mr. Yoichiro Yajima.

She was handicapped at the time, which meant she was in a wheelchair.In this ruse, the low eye level is very beneficial to the murderer.Mr. Toyozo pushed her wheelchair, pretended to be looking for Mr. Yoichiro Yajima, cleverly brought her to Gotokuji's house, and took a shortcut as an excuse to choose a route across the farmland, which would inevitably pass by the greenhouse.Then, Mr. Toyozo asked her, who knew nothing, to observe the interior of the greenhouse. The scene she saw was the same as what you experienced just now.In her eyes, from the entrance to the exit is a space with nothing. She must never have imagined that there is another space outside this space, and her husband's body is there.After Mr. Toyozo asked her to read it carefully, he stayed with her and Mrs. Changdai until late at night.

Mr. Toyozo’s alibi is completed. After that, you only need to seize the time and go to the greenhouse alone in the middle of the night, dismantle the semi-conical greenhouse and go into the farmhouse. You only need to wait until the next morning when someone discovers that Mr. Yoichiro Yajima was murdered. dead in the central area of ​​the greenhouse. Later the body was found, and the police began to search, presuming that the time of death was three hours from 8:00 p.m. to 11:00 p.m.However, it was immediately shortened to one hour from ten to eleven in the evening.The reason is that someone confirmed that there was no abnormality in the greenhouse at ten o'clock in the evening. This person was none other than the wife of the deceased.Mr. Toyozo's alibi for this time period is of course perfect. In this way, he skillfully stayed out of the scope of the murder case ten years ago. "

Shiki listened to the explanation of the Sunagawa Police Department, and thought about the wonderful testimony of a certain white-collar family about the murder case ten years ago. The white-collar worker had entered the greenhouse where the crime took place to have a urinate at midnight, and confessed that there was no corpse in the greenhouse.This testimony, which sounded contradictory at the time, easily makes sense as long as it is explained in terms of double greenhouses.The white-collar workers only saw the semi-conical greenhouse on the inside, and didn't know that there was another space on the outside, where the corpses had always been.

"However, what is my husband's motive for killing Mr. Yajima Yoichiro? No, not only that, what is Shinichi's motive for killing his father? So far, Mr. Detective has only explained the method of killing, without mentioning the motive at all. No matter how vicious he is , and will not kill others inexplicably, not to mention that my husband and Shinichi are not extremely vicious people, there must be some reason." "The motive... This is indeed a question. As Madam said, I only know the motive of Iwamura's murder. Why did Mr. Toyozo kill Mr. Yoichiro Yajima? Why did Shinichi kill Mr. Toyozo? To be honest, I don't know, maybe it's just You can wait for Shinichi to confess."

"Mr. Police Department, wait a minute!" There was another sound from the corner of the room, and it was the detective again. "I have an idea for this puzzle. I can't answer two questions at once, but I think I can at least perfectly explain the motive of the murder ten years ago. What do you think?" "You know? It's not right to say that, but in this series of cases, you are only slightly related to the murder of Iwamura Keiichi, and you have almost nothing to do with it, isn't it?" "Mr. Police Department, you are right. For example, I just mentioned the murder process of the murder case ten years ago. I don't understand the meaning at all. Because I don't know what kind of case it was, and I don't know where the mystery is. , It’s like looking at the answer without looking at the question, it doesn’t feel right.”

"I think so. After all, I don't have time to explain clearly to you, an outsider. In this case, why can you explain the motive of this murder case? Motivation is the deepest part of the murder case. I really don't think you can understand it." "Did you say that I was an outsider just now? In the whole case, I am indeed an outsider in some parts, but this statement can also be applied to Mr. Police Department. You only correct it from one direction, only from the lucky cat view the whole case from the direction of the "What does it mean?" "I'll explain later."
