On the sidelines, Hattori Heiji and Conan, although they had listened to the whole fast-paced Q&A, had exactly the same doubts in their hearts as the female secretary at this time.
I saw Ye Gengyi turning around and walking towards the outside of the villa.
Hattori Heiji and Conan quickly caught up:
"Brother Gengyi..."
"The poison identification results show that the remaining seven cakes are not poisonous." Ye Gengyi said: "We already know the method of poisoning, but it is difficult to get her to admit it because of the lack of evidence, so after discussing with the police department, we decided to use The information gap breaks through her psychological defenses first and facilitates subsequent interrogation."
Hattori Heiji:"……"
Conan: "..."
No... Why did you team up with the police to solve violent puzzles? ? ?
Both detectives felt like they had nothing to complain about.
It was inconvenient for Conan to ask, so he bumped a certain black man with his elbow.
Hattori Heiji understood and quickly asked:
"Wait a minute, Brother Gengyi, so...since only the piece of cake eaten by the deceased was poisonous, how did she make the deceased choose that piece? I just asked Heye and the others in the study, and it seemed that the deceased was When eating cake, grab the piece furthest from your body.”
That's right, how did the murderer do it... Conan held his breath and listened carefully.
He felt that Ye Gengyi must have seen through the murderer's trick. Otherwise, if the probability was 50 to 50, then even if the female secretary had just said, "Even if she poisoned her," there was no reasonable explanation. recognize.
And, most importantly, Ye Gengyi finally said that the female secretary wanted to frame Mrs. Wakamatsu and poison her...
At that time, he saw the expression on the female secretary's face. When she looked at Ye Gengyi, she seemed to be looking at a non-human being.
The kind of leakage of emotions caused by surprise is clearly a reaction to being guessed.
You can’t go wrong!
The two detective boys looked expectantly.
Hattori Heiji couldn't help but urged:
"Oh! Brother Gengyi, stop being so secretive and tell me quickly!"
It's so noisy...
Ye Gengyi's eyes were dead, and he had no interest in talking at all.
"Brother Geng Yi! Brother Geng Yi!"
"..."
Ye Geng turned his head and looked at a black chicken that was shouting:
"The principle is very simple..."
"Uh-huh……"
Hattori Heiji quickly shut up.
Ye Gengyi continued: "Imagine standing alone in a room late at night and turning off the lights."
Turn off the lights?
Hattori Heiji looked confused.
Ye Geng said: "To put it simply, you are still there, but the range of black in your senses has become larger."
"???"
Hattori Heiji had a question mark on his head.
Pfft... Although Conan didn't know what this matter had to do with the case, he couldn't help laughing.
"Conan." Ye Gengyi looked at a certain big head.
"ah?!"
Conan was agitated and quickly suppressed his smile, fearing that he would be taught a lesson again.
"Tell Mr. Maoli that I will go back first and let him drive the car back to the office. I will go there when I have time."
Ye Gengyi drove another car when he came over in the evening. Since the murderer had been found and it had nothing to do with supernatural incidents, he would not delay here.
"I understand~" Conan nodded obediently.
Watch Ye Gengyi walk out of Wakamatsu's house.
Conan suddenly felt a chill on his back. He looked up and saw a dark face in front of him.
Hattori Heiji looked at him, curled his lips, and said in a voice that would definitely give people goosebumps when imitated by a high school student:
"What the 'I know~' Kudo, why don't you stop me?"
"It's not the first day you've met Brother Gengyi. He doesn't want to explain what I can do, and..."
Conan smiled: "This is the first time since the last incident that Brother Gengyi has asked me to convey something. It shows that my recent performance is not bad, and he should not be angry anymore."
"hehe……"
Hattori Heiji's half-moon eyes: "I think maybe it was because of you that Saradachi helped the police find the real murderer and then left in a hurry."
"What are you so angry about?"
Conan stared blankly and said: "It was obviously you who was chasing Brother Gengyi and shouting here and there, only to have him describe it as the black area getting bigger..."
He stopped talking, swallowed the last few words silently, and then murmured:
"Could it be that... what Brother Gengyi wants to remind us is an optical illusion?"
"Eh? What kind of optical illusion?" Hattori Heiji's mind was filled with memories of a certain professor named Ye complaining about his shame.
"cake!"
Conan said seriously: "The murderer must have used some method to make one of the remaining two pieces of Baumkuchen look larger."
"Please, how is it possible..."
Hattori Heiji was about to retort.
Suddenly, a thought came to mind:
"Could it be Jastrow's delusion?"
"Yeah. It's not wrong, the Baumkuchen happens to be fan-shaped after being cut." Conan breathed out... Finally one of the mysteries was solved.
"I see."
Hattori Heiji nodded: "No wonder Saraichi-san asked Miss Satake that deliberately before... If the police informed us in advance that the remaining seven cakes did not react with poison, then Miss Satake, who had been mentally prepared for this, would definitely act out of caution. No answers to many questions.”
"Ah! I understand." Hattori Heiji whispered again.
"Huh?" Conan looked confused: "What's wrong, Hattori?"
"That's what I just said."
Hattori Heiji said seriously:
"Although I still don't know why Gengichi thinks the murderer's next target is Mrs. Wakamatsu, but assuming that before the poison test report comes out, we still can't determine who the murderer of Mr. Ikuro is, then there is a suspicion of poisoning the cake. Miss Satake, there is indeed the possibility of framing someone as a frame-up."
Hiss, that’s it…
Conan also figured out the key, and suddenly felt excited all over.
correct……
This means that even if there is only a hypothetical possibility, if Brother Geng is not able to find the murderer so cleanly, there will be another corpse in this villa in the next few hours.
He is still thinking.
In my ears, Hattori Heiji's voice came again:
"Kudo..."
"Um?"
"I suddenly feel that compared to Brother Geng, we are still far behind..."
"I have experienced this kind of thing for a long time."
Conan's half-moon eyes said helplessly:
"However, Hattori, you and I are the same type of people. We are both the kind of people who must find conclusive evidence whenever we find a mystery, otherwise we will not jump to conclusions easily."
"I did not mean that."
Hattori Heiji crossed his arms on his chest and said with a sullen face:
"Actually, when I went to 2-chome this morning, Genichi made fun of me once by using the color of curry. And just now, in such a short period of time, he actually thought of another way of making fun of me to prompt an optical illusion. Of course Brother Gengyi is very powerful, but what I mean is, am I really that dark..."
Conan: "..."
of course……
