Cotton hides ice needles!

"First of all, the lights in this No. 3 car have been vandalized, as evidenced by the small lamp on the red wooden table. Because only the lights are broken, the criminal plan can be carried out. After the train enters the tunnel, In the darkness, Honda used the murder weapon hidden in the pen holder to stab Akagi's neck. Everyone knows that potassium cyanide is a deadly poison, as long as it enters the blood vessels, it can cause immediate death. Once Akagi is dead, the remaining Putting the potassium cyanide in the water glass is easy, because Akagi is dead and can't stop..."

"Wait a minute, how did Mr. Honda know that Mr. Akagi would definitely sit behind him?" the flight attendant asked suspiciously.

There is no fixed seat for this train ticket. It is impossible to predict where Akagi wants to sit. And Honda Xiongji sat there from the beginning and did not change his position.

"No, Mr. Akagi took the initiative to change seats, and he took the initiative to sit over." He Ye said in surprise.

"Since he took the initiative to sit over, what does it have to do with Honda?" Yuan Gang Zhengnan looked dull.

"Idiot, think about why Akagi took the initiative to sit here." Heiji scolded.

"The lamp, because when the carriage was dark, he took the initiative to come over because of the lamp." He Ye said loudly.

Heiji nodded and smiled with satisfaction: "Yes, it's because of the desk lamp. There is no desk lamp in the carriage itself. The desk lamp is fixed on this desk. In order to see things clearly in the dark, Akagi naturally sits over."

"However, this doesn't prove that the murderer is Honda. Besides, he doesn't even know what the murder weapon is." Katsu Nanako said helplessly.

"The murder weapon? If I'm not mistaken, the murder weapon is actually an ice needle with a pinhole-like head and a large tail. This ice needle is mixed with a large amount of potassium cyanide."

The people present were immediately shocked and looked incredulous.

Honda Kumaji's face changed greatly, his pupils shrank, and he looked at Heiji in disbelief.

[How did this little devil know? Impossible, he must be confused. ]

"But how did Mr. Heiji know?" the flight attendant asked curiously.

"Akagi's collar was wet, and the fogged water droplets on the mirror were evidence." Heiji explained.

Everyone suddenly realized that it was the reason Heiji took the mirror just now.

"It's a joke, even if it's true as you said, the murder weapon is an ice needle with a thick head and a big tail. May I ask how I brought it to the train. You know, if it's not iced, it will evaporate quickly." Honda Kumaji sneered.

"Oh, that's why I said the pen holder is evidence." Heiji said confidently.

Boom!

Honda Kumaji trembled in his heart, looking at Heiji with a hint of panic in his eyes.

[Why is this kid so confident in his eyes? Could it be that he really cracked my technique? ]

"Maybe many people don't know that wrapping ice cubes with dry cotton can achieve the purpose of storing ice cubes and prevent the ice from volatilizing as much as possible. Your method should be to completely hollow out the pen and then put the ice wrapped in cotton. The needle is put into the pen holder. Of course, this ice needle is made of a large amount of potassium cyanide and water. It melts quickly. And the water droplets in the pen holder are water droplets atomized by ice needles, and you can smell a hint of almond, which is the proof."

There was silence in the carriage, and Heiji's reasoning was truly shocking.

Honda Kumaji's expression completely solidified, and his eyes were full of horror.

[Why does this kid know this, my criminal methods are obviously flawless, why does he know this, as if he saw it with his own eyes. Impossible, this is impossible. ]

"But Mr. Heiji, the water droplets in the pen holder have disappeared." Katsu Nanako said softly.

Honda Xiong Er was like a drowning person grabbing a piece of driftwood, full of confidence: "This can't be used as evidence at all, and I remembered that I washed the pen last night, and it should be the water droplets left at that time. . As for the almond smell, you must be smelling it wrong."

"Looks like you're planning to plead not guilty, right?" Heiji was still winning.

"I'm not a murderer, why should I plead guilty." Honda Xiong Er said hideously.

"The pen holder is just one of the evidences, and it is not the decisive evidence. The decisive evidence is here."

Heiji picked up the pack of tissues, opened it, and took out the tissues one by one.

Suddenly, a piece of paper floated out from the inside and landed on the table, full of words written on it.

"This piece of paper should be the one that Chimu looked at before. I believe that Chimu's fingerprints can be detected from it. The note before Chimu's death appeared in your hand, which is enough to prove that you are the murderer. However, there is another The evidence leaves you without excuse. That's..."

Heiji took out a ball of damp cotton from the tissue bag, and the people at the scene immediately covered their noses.

Such a strong almond flavor! ! ! ! ! ! ! ! ! ! !

Seeing that ball of cotton, Kumaji Honda's face changed completely, and his eyes showed a smear of ashes.

"This should be the ball of cotton you used to keep the ice needles. Now, do you still want to deny it?" Heiji said confidently.

Honda Xiong Er clenched his fists tightly, and it took a long time before he let it go decadently.

"As expected of Hattori from Kansai, I'm convinced of this reasoning ability. That's right, Akagi was killed by me. Who let him know that I used the position of the section chief for corruption, and got the evidence. In order to get rid of His threat, I decided to kill him, one hundred and one hundred. I think the whole plan is flawless, but unfortunately, you can't be counted here." Honda Xiongji lost his face.

"Humans are flawed, and only machines can be perfect. In front of a mechanic, all crimes will be invisible."

Heiji's body was full of momentum, full of confidence.
