"Of course, I'm just providing some ideas. The specific investigation method still needs to be decided by you, the police department."
Ye Geng threw back the initiative.
He has also said before that it is difficult to leave evidence in such a probabilistic case, because the murderer cannot guarantee 100% that his method will be successful at the moment the target person actually dies.
Mumu Shisan obviously also understood this truth and made a decision after pondering for a moment.
The three of them came to Wakamatsu Serika's study together.
A burst of heated conversation came from the room.
Listening carefully, it seems that Conan, Mouri Kogoro, Hattori Heiji, Toyama Kazuha and Mouri Ran are asking the maid about the missing text in the bathroom.
"You said that the English letters left by the president before his death couldn't be EYE, right?"
"EYE?"
The maid looked confused: "What I saw was the letter S, and there was something else below, but it was blocked by the president's hand."
Since the first letters of the Roman pinyin of Shiina, Junsei, Satake, Serika, and Sakurako in Japanese are all S, her words can be said to have directly fixed the scope of the suspects who killed Wakamatsu Kohei in this study.
From the murder of Wakamatsu Kohei to the murder of Wakamatsu Ikuro, the murder methods may be different, but the only thing that remains unchanged is that the detectives are 'playing' this trick every time...
As soon as Ye Geng thought about it, he paused as he walked into the study and looked down at the floor.
The murderer prefers to play with probability, so he just added a layer of insurance out of caution. Unexpectedly, it was the nanorobot attached to the sole that first detected the poison reaction.
[Sir, the mixture of cyanide and ground dust in the soles of shoes is about 10 mg. 】
Ye Xiaobai quickly gave the scan results.
Hmm...did they accidentally spread it here? Then why didn't the police find poison on them during a body search?
Ye Geng thought and calmly circled around within a 1.5-meter radius of the detected poison.
Then he looked at Wakamatsu Serika sitting behind the desk.
If the poison was on clothes, it would not be spread out so evenly... The poison was on the slippers.
Was she the one who poisoned me?
wrong……
Given the size of that piece of Baumkuchen, if Wakamatsu Serika had had the experience of being a waiter in the cafeteria before taking over as president, she would have definitely shaken the poison on other cakes when she poisoned it.
It seems that the murderer deliberately mislead in order to avoid being held responsible for the murder.
She was still worried that if the police could not find evidence, they would regard her and the maid as the prime suspects with a 50% probability of murder, so she prepared such a move.
Don't worry about this kind of vague clue. Let's see what she says.
"Miss Satake, we have found new clues in our investigation. Please come with us..." Here, Megure Thirteen has already begun the operation of false confession.
"Ah? Me? Okay..."
The female secretary hesitated a little, but nodded and walked over.
Eh? ! No, no? !
Conan and Hattori Heiji were startled. After looking at each other, they no longer bothered to ask about the death message left by the maid Wakamatsu Kohei, and hurriedly chased them out.
A certain detective boy still didn't dare to get too close.
Hattori Heiji thought about it and stood at a distance where he could hear the conversation between the four people.
One end of the corridor.
"Excuse me, how can I cooperate?"
The female secretary was the first to break the silence. When she spoke, she was very calm and showed no signs of guilt at all.
If he hadn't heard Ye Gengyi's analysis beforehand, Mu Mu Shisan would definitely have been confused by her acting skills.
Ye Gengyi said:
"Ms. Satake, were you present when the Megure Police Department introduced my identity?"
"Well, I was in the corridor outside the living room." The female secretary nodded.
"Okay, now I want to know more about the process of you and Miss Yonehara sharing the cake in the kitchen."
Ye Gengyi directly explained his intention.
"...As I said before, Ms. Mihara cut the cake, and then I helped put the cake on the plate, oh..."
The female secretary pushed up her glasses and added:
"I was also the one who asked Yonehara-san to cut the cake into eight pieces."
"In your arrangement, does the Baumkuchen belong to the deceased?" Ye Gengyi asked another question that everyone knew the answer to.
"Yes." The female secretary nodded.
"oh?"
Ye Gengyi continued: "In other words, you knew that the deceased complained that he was hungry before, but you deliberately didn't give him the cake when dividing the plates. Aren't you just waiting for him to take the poisoned cake?"
"I……"
The female secretary panicked, but she still explained: "At that time, I just wanted to share the cake with the guests first..."
"It's convenient to leave a poisonous cake, because you have ample opportunities to poison the cake." Ye Geng said with certainty.
"Of course not." The female secretary immediately corrected her: "You can ask your colleagues about this kind of thing. From the time when I bought the cake to when Mr. Yulang was poisoned and died, I am not the only one who had the chance to poison me, right?"
"You won't say that after the poison test report is delivered." Ye Gengyi said seriously.
"Huh? Haha..."
The female secretary was stunned, and her tense nerves suddenly relaxed: "Does that mean you don't have evidence yet?"
"It will be available soon."
Ye Gengyi said: "There are only two possibilities for the results of the test report. The first is that the remaining cakes on the dining car are poisonous, and the second is simply impossible."
"So, you mean, if the cakes in the dining car are not poisonous, I am innocent, right?" the female secretary asked with a smile.
"Of course not," Ye Gengyi continued to emphasize the fact that the other party was poisoned, in order to deepen the impression and expose the loopholes in the reasoning:
"Because even if only one piece is poisonous, you who are closest to the dining car still have enough time to poison. You can't deny this kind of thing. As for whether the deceased would take that piece, this kind of thing... this kind of thing..."
The female secretary's eyes lit up, she chuckled as if she was waiting for the other party to be slapped in the face, and asked eagerly: "Ha... even if I poisoned him, then you should tell me, if the two people left in the dining car at that time Only one piece of the cake is poisonous, so how did I let Mr. Yulang eat it?"
On the side, Mumu Shisan and Gao Mushe were dumbfounded. It was not until the female secretary said these words that they finally came to their senses.
"Okay, police department, she has admitted it. I will leave the rest of the sebum sampling to you."
Ye Gengyi did not forget to add another layer to this false confession, but the tone of his words was no longer so tense:
"Oh... Also, I suspect that she wants to blame Mrs. Wakamatsu for the murder. I cannot rule out the possibility of poisoning and committing murder again. I suggest that the villa, especially the study where Mrs. Wakamatsu works every day, be inspected."
"You...you..." The female secretary was stunned.
He hasn't even taken action yet, why would this person know that he wants to kill Wakamatsu Serika? !
