Chapter 99
No matter how shocked Conan was, the investigation of the case continued. After listening to Hoshikawa Kazuaki's explanation, Hagiwara Kenji exclaimed:
"I see. In that case, what happened to Ms. Arimori and Shinichi Kitajima is actually the same situation, right? Ms. Arimori, who was sitting in front of the window on the second floor of the library, was also misled by the ancient trees behind her when she looked at the path in front of the ancient trees.
Although she could clearly see the people walking on the empty path, she could not see clearly whether there were other people passing by in the dark in the ancient woods behind the path.
Kitajima took advantage of this visual error and was able to move freely between his and Sakai's dormitories without being discovered by Ms. Arimori who was sitting on the second floor.
It seems that the pressure marks with sequins stuck on them that I found in the pile of rotten leaves in the ancient forest this morning were actually the marks left by Bei Dao when he passed through the ancient forest the night before.
As expected of Mr. Maori, he saw through this deceptive trick right away! And of course, there is Xiaoxing, I didn’t expect your observation skills to be so sharp now! "
Xingchuan and Ming just smiled modestly and said:
"I'm not as amazing as Yanji said. I was just inspired by Mr. Maori and suddenly thought of what happened at that time. And strictly speaking, Mr. Maori is the real amazing one.
He didn't see the scene in the collection room at the time, but he suddenly thought of this while solving the case. It seems that I will have to rely more on Mr. Maori's wisdom in future cooperation."
Maori Kogoro was still sitting in the corner calmly, looking completely calm and unfazed in the eyes of others. However, Conan, who was hiding in the dark, had a headache after hearing Hoshikawa and Akira talking about their future cooperation with Maori Kogoro.
Why did Hoshikawa say such a thing? Could it be that he wanted to find out who the person who made the brilliant deductions behind Kogoro Mori was? If he paid a little more attention in the future cooperation, he might really reveal the secret of impersonating Uncle Mori to make deductions on the spot.
Oh, this is really too bad. Damn it, when did Xingchuan start to doubt me?
No one knew the infinite sorrow in Conan's heart at this time, and everyone's attention was shifted to the case.
Ida Ko looked at Kitajima Shinichi, whose eyewitness testimony had been exposed for loopholes, and saw that he no longer had the confidence he had before when he firmly stated that he was innocent. Instead, he suddenly wilted like an eggplant hit by frost, and his face even looked pale and almost withered.
"Bei Dao, the excuses you made for yourself have been completely overturned. At this point, you should stop struggling. It is better to tell the truth about how you killed Sakai and where the poison in your hand came from. Have you ever given the poison to anyone else?"
Who would have thought that Kitajima, who originally had a very unpleasant expression, actually laughed like a lunatic after hearing Ida Ko's question. He laughed for a long time before he asked back in a very strange tone:
"Mr. Officer, what are you talking about? Where is the poison? Also, when did I ever say that I made excuses? I didn't poison him. Even if you bring me a lie detector, I will still say that I didn't poison Sakai. That guy clearly committed suicide. Please don't embarrass me anymore, Mr. Officer."
Ida Kou frowned, not understanding where this guy got his confidence from. And he was fine before, how come Kitajima Shinichi suddenly became evil after just one sentence?
If Bei Dao was just a highly intelligent criminal who could deal calmly with the police before, he now seems like a perverted serial killer who completely disregards rules and morals and is willing to commit crimes for fun at any time.
Conan, who was still nervous before, was also shocked by Kitajima's sudden change at this time, and immediately focused on the case. He continued to speak in the voice of Maori Kogoro:
"Although you have always insisted that you did not poison Sakai, you cannot deny that Sakai was poisoned to death under your design and inducement. It is a fact that you maliciously poisoned Sakai to death. You cannot deny your crime just because you did not put the poison in the tea yourself."
Kagino Tomomi didn't have the patience to listen to such complicated reasoning, and couldn't help but urge:
"The poison wasn't planted by Bei Dao, so could it be that he tricked the deceased Sakai into poisoning himself? Oh, Detective Maori, please stop talking about this, it's really annoying to me."
Who would have thought that Maori Kogoro would actually say:
"Yes, that's right. The deceased was indeed deceived and induced by Bei Dao to put the poison into the protagonist's mouth, helping Bei Dao complete the last step of poisoning."
Hearing this, everyone present looked at Bei Dao in surprise, and Bei Dao's originally weird smile froze on his face. Someone couldn't help but ask:
"What? Detective Maori, what is going on?"
Maori Kogoro said calmly:
"Do you remember that when we went to the cafeteria to rest after the tour, the chef told us that the deceased Sakai had taken three simple tea cups from him yesterday. And one of these three simple tea cups appeared at the scene of Sakai's death."
Ida Ko immediately found a photo of the scene from the evidence. In the photo, there was indeed a familiar simple teacup on the deceased's table. The forensic police officer nearby introduced:
"After inspection, we found that the drug that successfully poisoned the deceased was found on the outer edge of this cup. In addition, we also found drug residues on the inner side of the thumb and index finger of the deceased's right hand."
Date Kou pondered for a while after looking at the photo, then looked up at Maori Kogoro and asked uncertainly:
"Could it be that the murderer smeared the drug on the edge of the cup so that the victim's lips could touch the drug when he drank the tea, ultimately causing poisoning?"
After he finished speaking, before Kogoro Mouri could answer, he shook his head and denied his previous guess.
"No, that's not right. There's no way to explain the drug residue on the inside of the deceased's finger. And if the murderer really poisoned the deceased's cup while he was visiting, wouldn't the murderer's action at the time have aroused the deceased's suspicion? How could the deceased dare to continue drinking tea from this cup without any precautions?"
As Yida Ko spoke, he stretched out his right hand, curled up the other fingers, and only stretched out the thumb and index finger, imagining under what circumstances the deceased would have put medicine on both fingers.
Then his eyes immediately fell on the cup in the photo, and suddenly he realized:
"So it was that action! Could it be that the drug was stuck to the deceased's finger at that moment?"
Seeing how quickly Date Kou figured it out, Hagiwara Kenji couldn't help but feel curious:
"What are you talking about? Which move are you talking about?"
Xingchuan and Ming on the side immediately explained:
"Brother Yaner, do you still remember that during the lunch break in the cafeteria, the chef did the same movement many times while chatting with us?"
As he spoke, Xingchuan and Ming simultaneously stretched out their right hands, clenched their fingers, and made a gesture of holding a teacup in the air. Then they shook their fingers slightly, as if there was really a cup in the air that was gently rotating with his fingers.
Kenji Hagiwara's eyes lit up, and he obviously understood what Hoshikawa Kazuaki meant.
"So you're talking about the chef spinning the cup all the time. I remember the chef said he learned the habit of spinning the cup from the deceased Sakai, right?
So, when faced with a cup of the same shape, Sakai would surely be unable to resist spinning the cup with his fingers, right? So, the drug residue on Sakai's fingers was acquired when he was spinning the cup?"
However, Maori Kogoro denied it in a deep voice:
"No, in fact, it was quite the opposite. The deceased had first stained his fingers with a large amount of poisonous drugs, and then when he spun the cup, he inevitably smeared the drugs on his fingers on the outer edge of the cup.
And it was this habit of spinning the cup that ultimately became the last step for the deceased to help the murderer complete the poisoning."
"So that's how it is! So that's how Sakai was poisoned!"
"It's incredible that someone could come up with such a weird way of poisoning. Who would dare to spin the cup after this?"
The crowd immediately started to talk in a clamor. Only the chef standing in the middle turned pale after listening to Maori Kogoro's explanation, and couldn't help muttering to himself:
"This is terrible! This habit is really terrible! Change it, you must change it immediately! Really, why did I learn such a terrible habit?"
Date Ko once again confirmed the shape of the cup in the photo and the distribution of poisonous drugs provided by the forensic department, and finally compared it with the dominant hand of the deceased, and finally nodded in confirmation:
"So that's how it is. The poison that the deceased was poisoned with was actually put into his own mouth. I didn't expect this to be a murder case that looked like suicide. No wonder Kitajima has always emphasized that even if he was used with a lie detector, he would still insist that he had never poisoned Sakai. Because judging from the steps, the poison was really administered by Sakai himself."
He looked at Kogoro Mori who had been posing in the classic "sleeping" pose. If he remembered correctly, this senior Mori had been sitting there without moving for such a long time.
Date Kou frowned in confusion at first, but finally decided to focus on the case first, so he put aside his doubts and continued to ask:
"But there is still a question. If the poison on the deceased's cup came from the contact and contamination of his fingers when he turned the cup, then where did the poison on his fingers come from?"
