What Kumaji Honda said was right. He sat behind Takeo Akagi and wanted to put cyanide into the cup from behind without being discovered. It was indeed impossible.
[However, is that really the case? ]
Heiji lowered his head and pondered, there are four big doubts in this case.
[First, if you put cyanide into a water glass, more or less water will be splashed around the glass. But it was clear that the table was clean and there were no traces of wiping. ]
[Secondly, why is there a water stain on the collar of the deceased, and the almond flavor is far stronger than that in the cup. ]
[Third, what was the condition of the pinhole and blood hole on the deceased's neck, and what was its connection with the case. ]
[Fourth, the deceased can see what the contents of that piece of paper are, and whether it has been destroyed now. ]
Linking this series of doubts, it is clear that this case is far from being as simple as it seems on the surface.
"Damn it, this C-class case is really hard to mess with."
After asking the question, although Heiji had a conjecture, the clues he found were not enough to confirm his conjecture.
"I said, Mr. Detective, you should solve the case quickly. The next stop is my goal. I have to go to the Arctic Ice Sculpture Company for an interview, so don't delay my interview." Yuan Gang Zhengnan said unhappily.
"Yeah, I'm also ready to go to work." Kita Xiong Er agreed.
"Did you also get off at Mihua Station? So did we." He Ye said happily.
[Ice carving skills? ]
[ice? ]
[ice! ! ! ! ! ! ]
Heiji suddenly woke up, and there was a glint in his eyes.
"Mr. Yuan Gang is engaged in ice sculpture work?"
"Yeah, it's not just me, Honda and the dead Akagi are all ice sculptures. Speaking of which, we have worked together for three years. If it weren't for Akagi...I wouldn't necessarily leave the Antarctic ice sculpture skills." Yuan Gangzheng Nan said.
Heiji nodded, walked over to the deceased's body, and lifted his collar again: "Heye, bring your little mirror."
He Ye took out a small mirror from his bag and handed it to him.
Put the small mirror on the inside of the collar, and slowly, a mist of water appeared on the mirror surface.
[As expected. ]
A confident smile appeared on the corner of Heiji's mouth. It turned out that he was using this method to kill people. It was really unwitting and didn't even leave any fingerprints.
Coincidentally, when he was a mechanic in his previous life, he also used a similar method to kill a commercial giant crocodile quietly. Unexpectedly, he even got an axe in front of him.
[If it is this way, then that thing must be on him. ]
"Heiji, what are you doing?" He Ye asked curiously.
"We're solving a case."
A confident smile appeared on the corner of Heiji's mouth. If this was the way, then the murderer would be him. However, it still needs to be determined.
"Hey, there is a fingerprint on the water glass." Heiji suddenly stared at the water glass and pretended to be surprised.
[what? ]
The three of them were startled suddenly, and then looked at the water cup, a faint fingerprint could not be discerned if one didn't pay attention.
"Could this be Akagi's fingerprint?" Katsu Nanako said softly.
"I've compared it, it's not the fingerprints of the deceased. For confirmation, let's compare it too." A smile appeared on the corner of Heiji's mouth.
"Damn, I didn't kill anyone, why should I listen to you?" Yuan Gang snorted coldly.
"Are you sure you don't listen?" A cold light flashed in Pingji's eyes, which made Yuan Gang Zhengnan startled, and he couldn't help thinking of the scene before he got into the car.
"Hmph, I didn't kill anyone anyway, so what am I afraid of?"
Still stubborn.
"Then please hold the water glass with your hand along the fingerprints, remember that it is a false grip, otherwise I will treat you as the murderer if you destroy the evidence." Heiji said seriously.
"Cut, it's really troublesome."
Yuan Gang Zhengnan stretched out his hand and held the water cup. Heiji lowered his head slightly and smelled it without a trace.
"no."
"Hmph, of course not, I'm innocent, how could it be..."
Suddenly, Yuan Gang Zhengnan didn't dare to speak, and walked to the side directly.
Heiji withdrew the cold light in his eyes and looked at Katsu Nanako and Honda Kumaji.
"I'll come first." Honda Kumaji walked over confidently and repeated the above steps.
"This taste..."
The corner of Heiji's eyes twitched, and the murderer was ready to come out.
"Well, it doesn't seem to be my fingerprint." Honda Xiong Er laughed.
"Then...then let me do it." Katsu Nanako came over, posing to check her fingerprints.
"No, I already know who the murderer is." Heiji put his hands in his trouser pockets and looked confident.
"Ah, it's not me, it's not me, I can compare fingerprints."
Katsu Nanako turned pale with fright, she thought Heiji was talking about her.
"Sure enough, you killed him. It seems that you still hate him, but Chimu asked for it."
"It's not me, it's not me." Katsu Nanako cried.
"Then I'll call the police immediately." Honda Kumaji took out his mobile phone and wanted to make a call.
"Of course we have to call the police, but it's not Miss Nanako who is caught, it's you, Mr. Honda Kumaji."
"what?"
The people in the carriage were stunned and looked at Heiji with a shocked expression.
"This...what a joke, I'm sitting back to back with Akagi, with two chair backs in between. The most important thing is that if I want to poison Akagi's water glass, he will definitely find him immediately, let's talk about it. The fingerprints on the water glass are not mine either, proving that I am not the murderer." Honda Xiong Er explained in a hurry.
