At almost the same time in one day, two poisoning cases occurred in Karasuma's high school.
One of the deceased was Karasuma's classmate and friend at school, Kanda Akina, and the other was Miyamoto Sanae in another class of the same grade.
The two deceased persons were poisoned in exactly the same way. They were both poisoned by grinding aconite powder into their respective lunch boxes.
Considering the special lunch system of this high school, the difficulty of such continuous poisoning is undoubtedly quite high.
The boy was already mentally prepared for another difficult case, but what he never expected was that the case would be solved just the next day?
Just the next morning, the Metropolitan Police Department received a call. This was a call to surrender. The middle-aged man on the other end of the phone stated that his daughter was one of the criminals who poisoned the two female students.
The boy in charge of the case rejected the middle-aged man's offer to bring his daughter to the Metropolitan Police Department for interrogation. Instead, he took the initiative to come and visit her.
There is no other reason. He promised Karasuma yesterday that he would let her investigate together this time. If the suspect is brought to the Metropolitan Police Department for interrogation, Karasuma cannot participate according to the rules and regulations, but if he comes to visit personally If so, it can be avoided to a certain extent.
"Lu Zi, no matter what, you have to explain it clearly to the police officer, don't hide anything, and strive for leniency, do you understand?"
In the living room of the house, a middle-aged couple left these words and temporarily retreated to the bedroom.
At this time, sitting on the sofa in the living room, opposite the boy, Karasuma and the two accompanying detectives, was a female high school student wearing a school uniform.
The female high school student had long, slightly curly hair and good looks, but her face was pale and she kept her head lowered, as if she didn't dare to look at the people sitting across from her.
"What's your name?" the boy asked. Behind him, a criminal police officer opened the record book in his hand.
"...Riko Kuboi is a second-year student in Class E..." the female high school student replied softly.
Class E is the class where Miyamoto Sanae, the second deceased yesterday, belongs, while Kanda Akina and Kokarasuma are in Class A.
"Your father said you poisoned Miyamoto-san's lunch box?"
"Yes... no, no!" Kuboi Riko nodded subconsciously, but immediately shook his head violently and shouted with some excitement:
"I-I didn't know there was poison in it! I thought, I thought it was just a laxative!"
Her words made the boy keenly aware of the abnormality.
"First tell me everything you have experienced."
"Yes...yes!" Kubojing Luzi, who was already frightened, nodded repeatedly, and then said:
"The first thing happened the day before yesterday. When I entered the teaching building to change my shoes that morning, I found that someone had stuffed a letter into my indoor shoes. The writing on the envelope was ugly, and the addressee was: I……"
With that said, Kuboi Riko quickly took out a folded piece of letter paper and handed it to the boy.
The boy took a look and saw that the writing was indeed ugly and crooked, as if the writer had deliberately written it with his non-dominant hand.
As for the content of the letter...
[I know Kanda Akina from Class A is your competitor. If you don’t want her to be selected for this autumn drama festival tomorrow, come and make a deal with me. 】
[I have difficulty participating in the next regional tennis competition because of your Miyamoto Sanae from Class E. As long as you add something to Miyamoto Sanae's lunch tomorrow, I promise that I will do the same to Kanda Akina. 】
[What you need to add is a powerful laxative that can last for twenty-four hours and is not life-threatening. You can take advantage of your class E’s physical education class tomorrow morning. Be careful to add it to the sauce as much as possible, otherwise you will be noticed. 】
[If you have this idea, then as a code, use your utility knife to make a vertical mark on the lid of your shoe cabinet, and I will put the laxatives in your shoe cabinet before tomorrow. 】
[Never try to contact me. Once you do so, the transaction between us will be permanently canceled. Also, remember to deal with this note. 】
After reading the crooked letter, the boy handed it to Karasuma and the two detectives beside him. He thought briefly for a moment and then asked:
"What does the letter say about the fall drama festival and the regional tennis competition?"
"Both of these are competitions that our school often participates in. Because Kanda Akina from Class A is very powerful, she is the heroine in every drama festival. The main player in the regional tennis competition is always our Miya from Class E. Ben Sanae..."
"Is the candidate selected by default?"
"No, no! But it's almost the same..." Hearing this, Riko Kuboi lowered his head and said, "Because they are so powerful, everyone will vote for them every time they are selected for the contest. Others have no chance at all, so In fact, it’s no different from an unofficial decision..."
“Were the selections for both events originally scheduled to take place yesterday?”
"Well, it was originally supposed to be yesterday..."
Then both men were poisoned.
"Are you also from the drama club?"
"Hmm... But as long as it is a drama show with Kanda Akina participating, I can only be the second female lead..."
If what Kuboi Riko said was true, and this letter with crooked handwriting was also true, then the current situation was already very clear.
The two people who were poisoned yesterday were jealous of other students because of their excellent abilities.
Among them, Akina Kanda from Class A corresponds to Riko Kuboi from Class E.
According to Riko Kuboi, the heroine of this autumn drama festival must be Kanda Akina. This makes Riko Kuboi, who is also a member of the drama club but has always been worse than Kanda Akina, quite jealous.
So, when that mysterious letter appeared in her shoe cabinet, Kuboi was tempted.
After all, according to the description in the letter, this is not something harmful. It is just some laxatives that will cause diarrhea and prevent them from participating in the selection process the next day. It is not a poison that can kill people...
According to what the letter said, as long as Kuboi Riko gave laxatives to her classmate Miyamoto Sanae, the writer would do the same to her opponent Kanda Akina.
But what Kuboi Riko didn't expect was that the person who wrote the letter had lied to her. It was not a laxative at all, but aconite powder that could cause death.
Therefore, Miyamoto Sanae, who was "forced to kill", was completely panicked. After returning home yesterday, her parents noticed something strange. After some questioning, her parents called the police to report the case. thing……
