Mrs. Kujukuri had indeed come for this. After thinking for a moment, she began from the start. "A week ago, my husband was resting at home. I went out for a while, but when I came back, I couldn't find him anywhere."
"He rarely went out except for work, and even when he left the house, he would always tell me first. I found it strange, so I looked everywhere for him.
"No one was in any of the rooms. Then I suddenly remembered something and went to the magic basement he used exclusively. The moment I opened the door, I saw... saw him lying motionless on the floor. When I went closer and touched him, his body was already cold."
At this, Mrs. Kujukuri pressed a hand to her temple in pain. "I called the police and an Ambulance. In the end, the police concluded that my husband had poisoned himself—their examination found that the toxin that killed him was called 'aconitine.'"
"Aconitine?" Conan was a little surprised that it was not Potassium Cyanide this time. But as a diligent and studious Detective, he was not unfamiliar with this poison either. "I remember that it's a neurotoxin, mainly extracted from the leaves and roots of plants like Aconitum Carmichaelii and Aconitum Kusnezoffii. Just two milligrams can be fatal. Once a sufficient dose of aconitine enters the human body, a person can die rapidly in just a few minutes."
"Oh? You even know about aconitine. Isn't your knowledge a little too broad for an elementary school student?"
A voice suddenly came from the doorway. Conan whipped his head around and saw a dark-skinned man with blond hair push open the door and walk in.
...Boss Amuro? What timing!
Remembering what he had just said, Conan broke into a cold sweat.
