The first person to find out that Ryuhei Aizawa had committed suicide and called the police was Kokarasuma.

The reason is not so complicated, after leaving the school, the boy who has already realized the truth behind the case directly returned to the Metropolitan Police Department to interrogate the illegal doctor Shiraki Mamoru.

Since it's at the Metropolitan Police Department, the boy can't blatantly take Karasuma with him this time.

So, all of a sudden, Karasuma, who had nothing to do, but didn't want to just go back to class, planned to go to Ryuhei Aizawa, the suspect she thought was the biggest suspect at the moment, to see if she could force some more information to come out.

Then, when she went, she found that Aizawa Ryu was lying flat at home, and his body was half cold.

"Didn't I tell you to go back to class first......

Hurried to Ryuhei Aizawa's house, the first thing the boy saw was Kokarasuma standing aside.

This girl's character of going up every time she encounters these cases makes him very helpless.

"I also want to find evidence as soon as possible and catch Akina's murderer......" Karasuma muttered and retorted in a low voice.

"You suspect that you are wrong, Ryuhei Aizawa is not a murderer, he is just a victim of the murderer's use to blame the crime."

"Huh? What's what? ”

Leaving such a sentence, the boy did not discuss it with the shocked Karasuma again, but looked at the scene first.

In the living room of the room, Ryu Aizawa fell face down on the floor, his hands clenched tightly to his chest, his eyes widened, his facial features were hideously twisted, and he seemed to have suffered great pain before he died, and there were traces of liquid flowing out of the corners of his mouth.

His death is highly similar to the two previous deceased, Kanda Akina and Sanae Miyamoto.

It is clear that Ryuhei Aizawa also died of aconitum poisoning, which was confirmed by the police before the boy arrived.

At the same time, on the dining table next to him, there was also an open bottle of whiskey, and an overturned goblet.

"Where was the aconitum poison detected?" The boy asked.

"It's in a bottle."

The criminal policeman wearing gloves on the side raised his hand and gestured to the bottle of whiskey on the table.

"According to the results of the forensic examination, there is a residue of aconitum powder near the mouth of the bottle, as well as on the inside of the bottle that extends downward.

We therefore speculate that the deceased must have committed suicide by pouring aconitum powder into a bottle and then drinking poisoned liquor. ”

The boy did not respond, he looked at the bottle in front of him quietly, and suddenly asked:

"A paper pack to store the powder of aconitum aconite...... Or containers, found it? ”

"Huh?"

Hearing the boy's question, the criminal police were stunned on the spot.

"The deceased, it is impossible to hold these aconite powders in his hands all the time, right?"

With that, the boy turned to look at the detective and continued:

"This highly toxic substance, even if it is a suicidal deceased, will be kept properly before use."

“…… Be. ”

"So, the container that the deceased used to hold aconitum powder before this, have you found it?"

"I'm sorry, we've double-checked this apartment before, but, but we haven't found any similar containers, Mr. Shirakawa, please wait a moment and we'll ...... again"

"You don't have to look for it, you can't find it."

The boy shook his head slightly, interrupting the detective.

"Because the person who poisoned him was not him at all, Ryuhei Aizawa did not commit suicide, but was killed by someone."

With that, the boy looked at the bottle of whiskey again and said:

"Take this bottle back, immediately check the fingerprint information on it, and by the way, take it to all corners of the room...... It is important to check the doorbell, doorknob, or faucet switch in places that are easy to touch.

I think that in these places, there should be the fingerprints of the real murderers except for Ryuhei Aizawa. ”

"Yes!" The criminal policeman nodded immediately and quickly turned to leave.

After giving the order here, the boy did not stop, and turned and left quickly.

"Wooden man, where are you going? Do you already know who the murderer is? ”

Behind him, Karasuma followed with ease and sat in the police car with him.

"Drive." The boy glanced at her and acquiesced in her actions.

"Go to Wajing's house and catch the real murderer."

“……”

The continuous reversal and complexity of this case made the boy who had seen all the truth clear at this moment couldn't help but feel a burst of surprise.

Of course, what surprised him was not entirely how complicated this case was, what really surprised him was that the real culprit behind the design of this murder method, and always unwaveringly, killing several lives in a row, and firmly promoting the continuous progress of this plan, turned out to be just a girl who was still a school age?

At Wai's house, the boy sat on the sofa in the living room, quietly looking at Kuwai Luzi who was sitting across from him.

This time, there was not only Kokarsuma sitting next to him, but also Keiko Hatoyama, who was supposed to go back to college for classes, but they met together on the way, so they came with him by the way.

Over the past year, because of the activity of Kokarsuma and some reasons of Keiko Hatoyama's own body, she has rarely been in and out of the crime scene with the boy as often as before.

More often than not, it is the boy who tells her these processes as a story after solving the case.

Therefore, since it happened to meet today, the boy naturally would not refuse Keiko Hatoyama's idea of wanting to come together.

"Officer Whiteriver, you're here again."

In the living room, Michiko Wakai looked at the boy and said with a smile:

"Is there anything else you need to ask me?"

Michiko Kuboi's appearance is very good, but compared to her rival in the school, Kanda Akina, is a little worse.

Not only in terms of appearance, but for the two who are also members of the drama club, Michiko Kuboi's acting skills are also worse than Kanda Akina.

To say something that may be excessive, Michiko Kuwai is like a "subordinate substitute" for Kanda Akina in school, even if Kanda Akina herself does not have this idea.

The boy's gaze rested on Kusai's hair.

Of all the people involved in this case, Sanae Miyamoto, the second deceased, had neat short hair, which the boy noticed when he first saw his body.

And the No. 1 deceased, Kanda Akina, and the other previous suspect, Kida Ellie, both have long straight hair, among which Kida Ellie still has a long double ponytail.

Only Michiko Kukai is born with slightly curly hair.

This is exactly the same as the female hair that Ryuhei Aizawa's wife collected from the edge of her washbasin.

"Kusai-san, I just heard from your school that you took a leave of absence today." The boy asked, not responding to Michiko's previous inquiry.

"Well, I've been feeling a little uncomfortable because of this incident, so I want to take a leave of absence to rest......"

Luko Wakai replied, her expression extremely calm, and the boy just looked at her directly, and added:

"You took a leave of absence after Ryuhei Aizawa."

The words fell, and there was finally a slight change on the originally calm face of Kuwai Luzi.
