Conan wants to lie down but won't let him

"Brother Mori, Officer Megure, there's a huge difference here!" Fujiwara Hiroshi said calmly. "First, judging by the killer's final act of blocking the surveillance footage, he's definitely someone familiar with the museum's layout and surveillance systems. This raises a big question: if the killer knew about the surveillance cameras, why didn't he block or destroy them beforehand, instead of doing this at the very end?"

Fujiwara Hiroshi raised this question, and both Maori Kogoro and Inspector Megure fell into deep thought. Indeed, they were so shocked by the scene of the mobile armor killing people that they didn't think about this question directly.

"The answer is actually very simple. The murderer knew there was surveillance and let us watch the entire process of the crime, which means that these are what the murderer wanted us to see. So can we trust what we see? Why were there white paper and pen on the table at the crime scene? Was the murderer so thoughtful to prepare them? Didn't he destroy the evidence that exposed his identity afterwards? And after blocking the surveillance, what actions did he take afterwards?" Fujiwara Hiroshi continued to raise a series of questions.

That's right! Fujiwara's analysis was absolutely correct. If the murderer didn't know about the surveillance, then all the previous inferences were reasonable. However, if the murderer knew about the surveillance, then what we saw in the surveillance was what the murderer deliberately wanted the police to find, so the conclusion that the murderer was Mr. Kubota would not stand. Conan's inner reasoning was exactly the same as Fujiwara's analysis. It must be said that Fujiwara was really good at insight, able to analyze the murderer's criminal psychology from the perspective of an outsider.

"Inspector Megure, the pen used to write the suicide note has been found at the scene, and there are Mr. Manaka's fingerprints on it." The forensic officer handed the physical evidence to Megure.

"Inspector Megure, take out this pen and try to see if you can write something?" Upon hearing this, Inspector Megure took out the pen and was able to write something on the paper.

"Brother Fujiwara, is there anything wrong with this pen being able to write?" Inspector Megure asked curiously.

"This is the murderer's attempt to cover up his crime and making it even more obvious. It is precisely because of this action that he will be completely exposed in front of us." Fujiwara Hiroshi said confidently.

"Then let me start from the beginning and explain the reasoning." (Shouldn't there be a manual door closing and opening sound effect at this time?)

"The murderer must have planned and rehearsed the crime today in advance. That's why the news about the moving armor has been circulated, which shows that a plan had been made before. The murderer's plan and rehearsal were almost finished, so he asked Manaka to meet in this room today. After the murderer appeared, he first chopped Mr. Manaka, and consciously forced Mr. Manaka to the side of the table, and then reminded Mr. Manaka to look at the note on the table. Since the surveillance video is silent, I guess the murderer said he wanted to kill Mr. Manaka and let Mr. Kubota take the blame. The murderer must have got the note with Mr. Kubota's name written by Mr. Manaka in advance. In addition to echoing the painting of heavenly punishment, the dim environment of this room also provides convenience. The paper has been on the table all the time, and Mr. Manaka has never found it. Even when he was in front of the table, he still couldn't find it without the murderer's reminder." Fujiwara Hiroshi explained the reasoning while retrieving this section of the video and showing it to everyone.

Megure Inspector Maori Kogoro also discovered that although the video could not be heard, Fujiwara Hiroshi's reasoning and analysis were indeed the most consistent with the situation at the time. Because Mr. Manaka in the video clearly noticed the note on the table after he was weighed.

"Then the next part is very crucial. I will slow down the speed so everyone can watch it in slow motion." Fujiwara Hiroshi slowed down the speed, and only saw Mr. Manaka's expression suddenly shocked in the video, and then he turned around and saw the white paper on the table.

"So, from the slow speed, we can also see that Mr. Manaka didn't notice the paper on the table before. It was obviously after he got the hint that he focused his eyes on the table. This is consistent with my previous analysis. Let's continue watching." Fujiwara Hiroshi continued to control the video playback.

Everyone noticed that in the video, Mr. Manaka first grabbed the pen next to him and kept drawing crosses on it, instead of writing the criminal's name as everyone had previously thought. Then, after drawing for a while, his expression gradually became angry, and then he threw the pen away fiercely.

"What did you find after reading this paragraph? What I observed was that under the murderer's prompt, Mr. Manaka saw that the note had Mr. Kubota's name written on it, and it was written in his own handwriting. So, without any time to think, he subconsciously wanted to cross out Mr. Kubota's name. However, after Mr. Manaka crossed out a few times, he found that the pen could not write at all. It was a pen with a broken nib, so he threw the pen away fiercely. The evidence should be reflected on the note. If you observe carefully, there should be scratches on Mr. Kubota's name where Mr. Manaka wanted to cross out his name. Even if the pen cannot write, this mark will not disappear." Inspector Megure held the note up to the light and looked at it in detail. He indeed found a lot of scratches.

"There are indeed scratches, but we have just verified that the pen we found can write, right?" Inspector Megure still had doubts and confusion, and asked in confusion.

"This is what I just said about the murderer's attempt to cover up his crime and adding unnecessary details. I will explain this later. Let's continue watching." Fujiwara Hiroshi kept everyone on suspense and did not directly answer Inspector Megure's question. He continued to play the video.

Just as Mr. Manaka threw the pen away and was about to pick up the note, the killer took action, swinging his sword at Mr. Manaka, preventing him from touching the note. Then, he proceeded to kill Mr. Manaka by hacking him to death. He then pierced his throat with the sword and nailed it to the wall, creating a scene resembling a divine punishment painting. The video ended like this, and the surveillance camera was obscured, so we couldn't see the rest of the video.

"Okay! So, after throwing the pen, Mr. Manaka attempted to retrieve the note, but was stopped by the murderer. Why did Mr. Manaka reach for the note? After realizing the pen wouldn't write, he must have thought of manually destroying it. Apparently, the murderer had thought of the same thing, and he immediately wielded his sword to stop and kill him. From this, we can conclude that Mr. Manaka's goal was to destroy the note, and the murderer's goal was to preserve it. Since the murderer had considered blocking the surveillance footage, why were the note and pen still found at the scene? This shows that this is exactly what the murderer wanted us to find and see. Inspector Megure, Brother Mori, do you still believe Mr. Kubota's name on the note is credible? Could Mr. Kubota be the murderer? Clearly, Mr. Kubota is another target of the murderer's vendetta, and he's prepared to take the blame for the murder and go to jail." Fujiwara Hiroshi gradually unraveled the mystery, slowly approaching the truth. Director Ochiai became increasingly alarmed as he listened. He hadn't expected such a carefully planned operation to be so riddled with flaws.

"After understanding this relationship, we can finally reveal the murderer's fatal mistake. This foolish act will completely expose him. Inspector Megure mentioned earlier why he found a pen that can write. It is obvious that the murderer replaced it. In fact, if there is no replacement, everything is just speculation. Now that the pen has been replaced, the murderer must still be carrying it on his person before he could dispose of the evidence after the crime. Then the murderer is Director Ochiai, who is at odds with both Boss Manaka and Mr. Kubota! The murderer is you!"

Everyone looked at this nearly 70-year-old man in disbelief. What!?

"I think that the pen that can't write can definitely be found on you. Why do I say it's an attempt to cover up the truth, adding legs to a snake? Because in order to make everyone believe that it was Mr. Manaka who wrote the murderer's name, they replaced it with a pen that can write. In fact, there is no need. Because even if the pen that was found in the end is not able to write, it can still be inferred that Mr. Manaka threw the pen on the ground and broke it. If this action was not taken, everything would be just speculation, without any substantial evidence. It is also an act of adding legs to a snake, or it can be said that there is a loophole in a hundred precautions!"

"Actually, there's no need to go to all that trouble. The idea was to frame Kubota, ideally. If that wasn't possible, it would be just as well to admit it myself. That scoundrel Manaka is so unfaithful and treacherous, and Kubota has no regard for art. He can't even remember the basics of putting on gloves, not to mention that he only works at the museum to facilitate reselling. These two are like demons. I will judge and punish them," Director Ochiai admitted, pulling out his ineffable pen. "Perhaps this also mirrors the painting of divine punishment. The knight of justice was corrupted by the demon while hunting it. So, even though the knight judged and punished the demon, he couldn't avoid corruption himself. I hesitated, especially when Mr. Fujiwara handed me his business card, telling me to seek his help if I had any questions. But I decided to proceed with the plan. In the process of truly pursuing the judgment, anger and hatred clouded my mind. I felt like I couldn't turn back, and ultimately, I became infected by the demon's blood."

After finally confessing his crimes, Director Ochiai was ordered by Inspector Megure to be taken back to the Metropolitan Police Department. Before getting into the car, Director Ochiai, still handcuffed, looked up at the sky at a 45-degree angle. His expression, illuminated by the setting sun, was so tragic, like a hero's departure, a knight's fall, that it took a long time for the audience to recover.
