"Well, wooden man, that..."
In the police car, as soon as the detective nodded, Karasuma, who was sitting next to the boy, suddenly spoke.
"The aconite powder used by the murderer, I think I may know where I got it from..."
The boy didn't speak, just turned to look at her.
"We have always had an 'Herb Museum' in our school. There are many herbal specimens for display. If I remember correctly, there seems to be a Aconitum specimen..."
The boy didn't know much about the situation in Karasuma's high school.
"Can anyone enter your herbal medicine museum?"
"That's not true. Generally, it is only open to students at specific times, and people from the same class always go together... But! The school organizes students to take turns to clean the museum every week!
Every time there is a general cleaning, a group of five or six people go to clean. Not only do they have to mop the floor, but they also have to polish the inside and outside of the glass display cabinets! "
When she said this, Karasuma suddenly showed a look of disgust and disgust on her face. It seemed that she must have been on duty.
"If this were the case, I think the murderer would have had the opportunity to quietly take away the aconite specimens in the museum!"
"How are those specimens preserved?" the boy asked.
"Most of them are placed in glass display cabinets, and then... they are also packed in a glass bottle, with their respective names and numbers on the bottles.
correct! Although the bottles are also the kind with small locks that cannot be opened...but, the keys to those bottles are actually very easy to get..."
"What's the meaning?"
“I discovered it when I was doing my cleaning shift before. The keys to the museum cabinets and bottles were all kept on the desk of the dean of the school for safekeeping.
Although it is said that, because it needs to be cleaned every week, students who are on duty can go there and get the keys without even applying.
After all, the museum contains some common herbs, and there is nothing particularly rare or precious. Even if the key is placed there, no one will steal it..."
The meaning of Xiao Karasuma's words was obvious. Although it appeared that the school museum was very tightly protected, all kinds of specimens were locked.
But in fact, due to the school's negligent management and indifference, this strict protection has completely become a decoration. Anyone with this idea can steal the museum without anyone noticing. specimen of Aconitum.
Hearing this, the boy sighed softly, a little speechless.
"Let's go to the school first, and let's go to the museum to confirm."
"..."
The confirmed facts were exactly as Karasumaru had guessed.
The aconitum specimen in the school's herbal medicine museum is indeed missing one.
This was finally confirmed after the school took out the record books from previous years and carefully looked through them for comparison.
The main reason is that the specimens of the lateral roots of Aconitum are very small, usually only the size of a fingernail. In addition, the glass bottles in the museum contain many roots, so there has never been a case where only one is missing. noticed by anyone.
In short, the source of the aconite used by the murderer has been confirmed, but the clues have been broken again.
But immediately, new clues came again.
The boy had just come out of the Herbal Medicine Museum when the criminal police officer who had been investigating various information about the two deceased people in the school hurried over.
"Mr. Shirakawa! We have a clue!"
The detective first saluted the boy, and then said with some excitement:
"We found a suspect who may be related to both deceased people!"
As he said this, he opened the file folder in his hand and handed the file of someone in it to the boy. Little Karasuma on the side quickly leaned over to look at it.
This is the file of a young man. The photo looks like he is in his late twenties or early thirties.
The man is very handsome, with flowing short hair, and a gloomy temperament on his face like a literary youth. He is the type that is very attractive to some young girls.
The male's name is Aizawa Ryuhei, and it is clearly marked on the file that he is also the Mandarin teacher of Class E, second grade, and the club advisor of the school's drama club.
Class E, second grade, is the class of the second deceased, Sanae Miyamoto.
The drama club is the club where the first deceased, Kanda Akina, serves as the vice president.
In other words, this Mr. Ryuhei Aizawa knew the two deceased people at the same time. Whether he is the murderer or not, he is currently worthy of inquiry.
"..."
Soon, the boy met Mr. Ryuhei Aizawa in a classroom office in the school.
"The murderer committed such a despicable act! I will never forgive him! If we don't catch this bastard as soon as possible, we don't know what dangerous things will happen again! Now the students are very uneasy, and we teachers can't make up our minds. Come to class..."
Faced with the boy's direct inquiry, Aizawa Ryuhei's tone was very excited and angry.
To be fair, this young teacher does have good looks and a strong physique. Coupled with the temperament of a literary youth, he has quite a bit of the "yellow trait" that often appears in comics and likes to lure others to cheat. It's the type that is likely to disrupt the "school atmosphere."
Of course, it is wrong to judge people by their appearance.
"Do you have any clues about the murderer of the two students?" The boy looked at him and asked calmly.
"No!"
Aizawa Ryuhei's face suddenly turned red. He paused for a moment before continuing to speak in an excited tone:
"Akuna-san is a good student who studies very seriously! Miyamoto-san only cares about tennis! I simply can't imagine how someone would want to kill them..."
Speaking of this, a hint of sadness suddenly flashed deep in his eyes.
The boy didn't say anything, he just narrowed his eyes slightly and looked at him expressionlessly.
"Sorry, Officer Baihe, I just feel a little sad when I think of two such outstanding students being killed like this. They are obviously still so young... I'm sorry..."
As if aware of the boy's gaze, Aizawa Ryuhei sighed deeply, his expression gloomy.
"I understand, Mr. Aizawa, please don't be too sad."
The boy said and suddenly smiled, which made Karasuma next to him take a breath of air.
Because the boy's smile at this time was a super gentle and sunny smile like the big brother next door.
She understands! She understands so well!
Every time this wooden man shows this "weird" smile while investigating, it means that he has noticed some very important clues!
【What? What else did you find? ! 】
