Conan, hampered by his current elementary school identity, used a tranquilizer dart to shoot at Kogoro Mori.
The latter instantly felt drowsiness creeping in, and he automatically adjusted his posture to sit in the chair.
Conan took the opportunity, quietly hiding behind the sofa.
He used his bow tie voice changer to adjust to voice number 59, the one most similar to Kogoro Mori's:
"Mr. Suzuki, earlier I heard Ran say you went out to the courtyard for some air and weren't in the living room, right?"
Bai Ye looked at Kogoro Mori, sensing something strange.
How come the voice was coming from behind him? Was he talking with his butt?
Facing the gaze of Detective Mumu, he nodded and admitted:
"That's right."
"Everyone else except you drank coffee, but Mr. Aikawa didn't eat cake. Have you considered that the killer might have poisoned the coffee, but put an antidote in the cake?"
Aikawa's mother looked panicked, glaring at the sleeping Kogoro Mori:
"What, are you suspecting me? What evidence do you have?"
"You swapped out Miss Watanabe's poisonous chocolate, didn't you?"
"You... you're talking nonsense!"
"Things happened so suddenly, you didn't have time to deal with the swapped chocolate. After the police arrived, you stood in the living room for a long time, and the chocolate hidden in the inner pocket of your chest has melted. Now, all we need to do is take it out and compare the packaging to know the answer."
Aikawa's mother, with a tense expression, took out the chocolate, but still struggled:
"Even if my chocolate and hers have the same packaging, it doesn't prove I poisoned him."
"Indeed, that can't be proven, but what about the coffee cup? Even if you hurriedly washed the coffee cup, there's still pesticide residue that can be detected. How do you explain that?"
Aikawa's mother, seemingly hit where it hurts, lowered her head like a quail, wiping away tears:
"It was me who poisoned K彦... woo woo woo."
Seeing her confession, Detective Mumu was very curious:
"Ms. Aikawa, he is your son, why would you want to kill him?"
Aikawa's mother slumped down on the floor, admitting frankly:
"No, I'm his aunt, not his mother. Recently, my husband's business had problems and he owed a lot of money. To get his inheritance to pay off the debt, and for Jinzi's future, so... woo woo woo."
Seeing the criminal confessing, Conan emerged from behind the sofa, revealing a victorious smile.
Mr. Suzuki, I won this round!
"Wait a minute!"
Bai Ye looked around, finding that Conan was missing from the living room:
"I just have one question for everyone, does the pesticide that can be fatal have an antidote?"
Detective Mumu and Takagi looked at each other, their words lacking confidence:
"That... it seems there isn't, right?"
"That's it, if there's poison in the coffee, and an antidote in the cake. At most, it can only adjust the acidity and alkalinity, it can't completely neutralize the toxins. Even if it weakens the toxicity, the decomposed substances wouldn't taste very good. So many people have it in their stomachs, why hasn't anyone noticed? Moreover, everyone is fine now, as if they haven't been poisoned at all, don't you find that strange?"
The barrage of questions left Conan speechless.
Thinking carefully, Mr. Suzuki's words actually made sense.
Colorless and odorless poison and colorless and odorless antidote, only exist in novels.
If it's a pesticide that can be fatal, it's certain that there's absolutely no antidote.
If accidentally ingested, gastric lavage is the best course of action.
Even if other substances are added to adjust it, it's impossible to completely neutralize all the toxins.
But everyone is fine now, indicating that Conan's judgment was wrong.
"Hiss..."
Detective Mumu gasped, feeling that there was more to the case.
He looked at Suzuki Bai Ye for help, even changing his address:
"Suzuki-kun, according to you, why would the killer be 關谷香?"
Suzuki Bai Ye snorted, sitting down on the sofa opposite Kogoro Mori:
"This guy, Aikawa K彦, I'm sure everyone here knows him. Although he looks pretty good, his temper is terrible, he's very unpleasant. And at the scene, there are indeed three people who poisoned him at the same time."
Conan, hiding behind the sofa, was dumbfounded, completely shocked.
Three?!
That's not right... Did Mr. Suzuki discover clues that he didn't?
Upon hearing this, Detective Mumu instantly transformed into a fanboy:
"Suzuki-kun, who are the three you're talking about?"
"First, naturally it's Mr. Jidō. He poisoned the cigarettes, but unfortunately, it wasn't successful. As he said before, Aikawa K彦 always looked down on him. Even when he took his cigarette, he would tear off the filter before smoking. This can be found from the evidence, the cigarette and the filter are separate."
Detective Mumu nodded in agreement, both he and Kogoro Mori had discovered this.
Mr. Jidō was considered attempted murder, not the real killer in the poisoning.
"Second, is Aikawa's aunt. She had planned to poison Aikawa K彦 for a long time, and she had bought a bottle of pesticide and a neutralizer in advance, putting them in juice bottles and placing them under the counter in the kitchen."
Upon hearing this, Detective Mumu gave Takagi a wink.
The latter understood and went to the kitchen to find the two bottles Bai Ye mentioned, bringing them to the living room.
This is important evidence and will be taken back to the police station for analysis later.
Suzuki Bai Ye nodded, looking at Aikawa's aunt with an amused expression:
"The seller certainly didn't know you wanted to use pesticide to kill someone. The neutralizer provided is just a common alkaline food additive and cannot neutralize the poison. Logically speaking, the neutralization is ineffective, everyone drank the coffee with the pesticide added, they should have died, do you know why you all survived?"
Aikawa's aunt knelt on the ground, her head shaking like a rattle.
At the moment of confessing and pleading guilty, she suddenly realized that she was sorry for her husband and son.
Now that she saw a chance to live, she became very cooperative:
"No... I don't know."
Conan's pupils widened, revealing a 'I understand again' expression.
No wonder everyone who drank the coffee with the additive is fine, it turns out the pesticide was swapped.
As for the neutralizer, it should have been covered up by the taste if it was added to the cake.
As for the true killer who swapped the pesticide, all they needed to do was tamper with the coffee cup.
The relevant residual traces would naturally be washed away by Aikawa's aunt, who was feeling guilty.
What a clever way to kill with a borrowed knife!
Mr. Suzuki must have discovered some special clues to be so sure in identifying 關谷香.
Conan, hiding behind the sofa, spoke out Conan's analysis of the case for Suzuki Bai Ye:
"Because that bottle of pesticide was swapped for real juice."
After hearing the reasoning, everyone suddenly realized.
Mr. Jidō, seeing his beloved being suspected, took the blame on himself:
"One man does the deed, one man takes the blame, it was all me, it has nothing to do with Ah-Xiang!"
"Whether or not it's related, you don't get to decide."
Conan once again took over the conversation, helping Bai Ye complete the final piece of the puzzle in the case:
"Ms. Guan, after she was rejected when she delivered chocolate to Aikawa K彦, did she start to have murderous intentions? If she had directly poured the pesticide into the coffee cup, it would have been easy to find out. Therefore, she used a method she thought was very clever. However, this method of poisoning left the most crucial evidence!"
Seeing Kogoro Mori analyzing the case under Bai Ye's reminder, Detective Mumu secretly admired him in his heart.
This kid's reasoning ability compared to Kudo, probably only higher, not lower!
"Mori-kun, you hurry and say it, what evidence did it leave?"
"Conan, you go to the kitchen and look for it."
"Yes."
Under Kogoro Mori's 'instruction', Conan went to the kitchen to find the hidden pesticide, pouring it into a bowl.
Then, while everyone was focused on the pesticide, he quietly returned behind the sofa:
"After Ms. Guan confirmed that it wasn't strongly corrosive, she smeared the pesticide on the designated coffee cup. According to the order of distribution in a clockwise direction, it's easy to determine the cup the deceased would drink from. Even if someone investigates afterwards, the blame can still be easily passed off!"
Guan Xiang's face turned pale, she argued:
"Empty words, what evidence do you have?"
Ran's father has already finished analyzing and reasoning about the case.
The identification stage finally came to Bai Ye's turn.
He stared at the red light on Guan Xiang's finger, raised his right index finger, and struck a very handsome pose:
"Geese leave shadows, ants leave traces! Confess, the pesticide residue on your finger is the best evidence!"
