"Do you have any guesses about the person who wrote you this letter?"
In the living room, the boy looked at Kubojing Luzi who kept his head down and did not dare to look at him, and asked.
"Yes, yes! It's Kida Airi!" Kuboi Riko replied immediately.
Hearing this name, Karasuma was stunned for a moment, and the detective on the side immediately recorded it.
"What's the reason?" the boy continued to ask.
"Kida Airi and Kanda Akina are both classmates in Class A. If she wants to poison Kanda Akina, it will be very easy...and! She is a member of the tennis club like Miyamoto Sanae, and, and Same as me..."
Kuboi Riko finally said the same thing as her, referring to the fact that Kida Airi was probably suppressed by Miyamoto Sanae in the club. Although she also had good strength, she was just a little behind Miyamoto Sanae. Therefore, he cannot be selected in many related competitions.
"I already guessed it when I saw the letter. The person who wrote the letter must be her. After all, she is the only one in school who can compete with Miyamoto Sanae in tennis..."
"..."
After finishing the interrogation of Kuboi Riko, the boy and Karasuma left the Kuboi house, but instead of returning directly to the Metropolitan Police Department, they changed their plans and went to the house of Kita Airi mentioned by Kuboi Riko.
"Mr. Baihe, we have just confirmed with the school that both Class A and Class E had an outdoor physical education class at a staggered time in the morning yesterday.
Moreover, Airi Kida from Class A and Michiko Kuboi from Class E have indeed taken leave to go to the teaching building during class time..." A detective said from the co-pilot in front.
"How's the fingerprint collection going?" the boy asked.
"The collection has not been completed yet. It is expected to be completed by noon today, but the fingerprints of Airi Kida and Riko Kuboi were collected yesterday..."
"Notify the Forensics Department and ask them to give priority to comparing the fingerprints on the lunch boxes of these two people and the two deceased people... In addition, continue to have people go to the school and students to inquire about the daily relationship between these four people."
"yes."
Having said this, the boy seemed to suddenly realize it. He turned to look at Karasuma who was sitting next to him and asked:
"How is the relationship between Kida Airi and Akina-san?"
Both of them are classmates with Karasuma, so she should be familiar with them.
"Basically there is no interaction..." Xiaokarasuma heard this and replied: "Akiuna has a very gentle temperament. Although she is very talented in drama performances, she has always been a bit shy and is not very good at dealing with those who are outgoing and proactive. people……
Kida Airi is such a person. She is good at sports, popular, and has a somewhat carefree personality. She has many friends in school... The two of them have a natural repulsion in personality, so they have always been just ordinary classmates... …Ah, but. "
Speaking of this, Xiao Karasuma seemed to suddenly remember something and said again:
"But the relationship between Kuboi Riko and Miyamoto Sanae should be very good."
"Why do you say that?" the boy asked.
"Because when I used to go to the drama club to see Akina, I would often see Miyamoto Sanae waiting for Kuboi Michiko. Although the two of them are not in the same club, they seem to have always had a good relationship. I heard that the two of them used to be Studying in a middle school..."
"Are you drugging your best friend..." The boy frowned slightly.
In the previous interrogation, Kuboi Riko did not say that she and Miyamoto Sanae were good friends.
The boy realized something for a moment.
"Mr. Shirakawa, we are here."
At this moment, the police car slowly stopped in front of a private house. The words "Kida Family" were written on the door plate next to it.
"Let's go."
He immediately opened the door and got out of the car, and the boy stepped forward and rang the doorbell.
"……who is it?"
A timid voice came from the door, and then the door was opened a little, and a female high school student with twin tails poked her head out to take a look.
"babble--"
But as soon as the female high school student saw the boy's face clearly, she suddenly seemed to have seen something extremely terrifying. She screamed and quickly closed the door.
Apparently, the female high school student was Airi Kida, and she also recognized the boy as the police officer who came to the school to investigate yesterday.
"Snapped!"
The boy struck out at the speed of light, holding the door at the last moment before it was shut.
"Kida-san, we have something to ask you."
The boy said through the door. Although he could easily push the door open with his strength, he did not do so in the end. He just refused to let Kida Airi close the door.
"No, no! I didn't kill anyone! I didn't kill Akina-san! Don't come to arrest me, you guys!"
Behind the door, Airi Kida screamed while desperately trying to close the door.
"I've already said, I just want to ask you something, I don't want to take you away..." The boy sighed softly.
"But! But Qiuna has already..."
"Kida-kun, I think you have seen my name in some newspapers before, so I hope you can trust me. At least when it comes to finding the murderer, I have never made a mistake so far.
Since you said the murderer was not you, I hope you can cooperate with us to find the real murderer as soon as possible so that you can clear away the suspicion. "
The movement inside the door gradually died down, and after a while, Kida Airi slowly opened the door a little more, stuck her head out, and looked at the boy outside the door with a scared look on her face.
"Are you really not here to catch me?"
"If the police want to arrest someone, they won't bring your classmates." The boy gestured to Karasuma behind him and replied with a smile.
But unlike the boy's relaxed expression, Xiao Karasuma's reaction was not that good. She crossed her arms, turned her head, and snorted coldly, her expression cold.
After all, to her, the person in front of her was undoubtedly the culprit who poisoned Akina-san, causing her best friend to die from the poison.
Being able to hold back and say nothing was already a great exercise of restraint on her part.
"Um……"
Not daring to look at Karasuma at all, Kida Airi quickly lowered her head and finally opened the door.
"Come in, you don't need to change your shoes..."
She turned around and led everyone towards the house.
When the boy came in, he instinctively glanced at the shoe cabinet at the entrance and frowned slightly.
"Are you the only one who lives here?" he asked.
The boy noticed that although there were other indoor slippers in the shoe cabinet, they were all a bit dusty, as if no one had used them for a while.
"Well, mom and dad often work away from home and rarely come back."
Taking a few people to sit down in the living room, Kida Airi hurriedly took out a letter from the bedroom and handed it to the boy without waiting for the boy to ask.
"That's it...the real murderer must be Kuboi Riko, and I was used by her!"
