In Conan, people have a brain option system.

Chapter 47 Control
"Come to think of it, Officer Chiba has also met that Akikawa brother before."

When detective Chiba Kazunobu heard Conan's words, he looked towards Akikawa Sorasuke who was at the innermost part of the house.

Then a look of surprise appeared on his face.

"Isn't this Akikawa Sosuke, the victim of the previous highway accident?"

"If it was him, based on his experience, it is indeed impossible for him to be in the situation that Miss Sera just described."

In order to protect Akikawa Sosuke's privacy, Chiba Kazunobu did not tell him what happened before in person.

However, the words of this Chief of the Metropolitan Police Department's Inspection Division were convincing enough.

"About what I just said, the evidence at the scene."

"Everyone, please look——"

As Sera Masumi said this, he came to the door of the laundry room.

On the door handle here, there is a very obvious bloody palm print.

"Inspector Megure, could you please ask the officers from the forensic department to investigate the fingerprints on both sides of the door?"

Inspector Megure nodded, then looked at a detective behind him and slightly raised his fat chin.

The detective in the forensic department understood what he meant.

He put on white gloves, took out the powder used for powder development to detect fingerprints, and the luminol reagent for revealing bloodstains, and walked to the door.

A few moments.

The detective from the forensic department said:

“Although there were palm prints on the inside door handle, no fingerprints were found.”

"In addition, probably because the force when grabbing the door handle was too strong, the blood covered the palm print and no obvious palm print was left."

"The outside door handle was wiped, but no fingerprints were found, and it also did not react to the luminol reagent."

The detective's answer made Kogoro Mouri, Kazunobu Chiba and others look regretful.

However, there was no change in Conan and Sera Masumi's expressions.

"Excuse me, are there any traces of smearing on the palm print on the inside of the door handle?"

"No, the palm lines are not blurred. It should have been scratched only once. There are no signs of multiple scratches or deliberate smearing."

"Sure enough, as expected."

As Sera Masumi said this, he looked at the cleaning staff who was the first person to discover the crime scene.

"You just said that when you found the body, you found the laundry room door open, right?"

"Yes."

The cleaner nodded.

"I was too scared to go in."

"So what exactly do you want to say?"

Kogoro Mori became a little impatient and hurriedly urged.

However, his urging was met with a cold stare from Megure Jusan.

"You are a famous detective, but you are outdone by a child of your daughter's age. Don't you feel ashamed?"

"I'm doing this to give newcomers a chance to perform."

Kogoro Maori said awkwardly.

"The outside door handle was not stained with blood, but it had been wiped."

"But there were obvious bloodstains on the inner door handle, which had not been wiped off."

"That means the murderer had enough time to deal with traces when he first entered the laundry room."

"He may have touched the door handle directly with his hand, or the victim may have touched the outside door handle."

"In either case, he must have made the decision to kill in advance, and in order to leave no evidence, he wiped the marks on the door handle when he entered."

"In other words, this was not a spur-of-the-moment act, but a premeditated murder."

Masumi Sera narrowed her unique deep green eyes.

"And according to the first eyewitness, she could see the body inside directly from outside the door." "In this case, isn't it unreasonable not to lock the door?"

"It would be better if the body is discovered as late as possible, but he still didn't close the door, so there is only one possibility -"

"Something unexpected happened at that time, causing the murderer to flee the scene in a hurry."

"At the same time, the bloody palm print on the inner door handle also proves this."

"There was clearly no blood on the outer door handle, but it was wiped by the murderer."

"There was an obvious bloody palm print on the inner door handle, but it had not been wiped off."

"This can only mean that the murderer was in a panic when he left and had no time to deal with the palm prints at all."

After listening to Sera Masumi's reasoning, the people around him suddenly realized.

"I see. No wonder you were asking, Miss Sera, whether the palm print on the inner door handle had been smeared."

"The outer door handle was not stained with blood, but the murderer still wiped it, which shows that the murderer is a very cautious person."

"He grabbed the inner door handle once with his bloody hand, but he did not deal with the palm prints on the inner door handle. This can only mean that the murderer panicked at the time!"

Chiba Kazunobu finally understood. He looked at Sera Masumi and felt great admiration in his heart.

The high school detective in front of me.

But all of this had already been deduced before the detective from the forensic department verified the palm prints and fingerprints!

"Let's go back to the topic at the beginning. By observing the wounds on the head of the deceased and Akikawa, we can see that Akikawa's wound is much more recent than the deceased's."

"In this way, it becomes clear why the murderer fled the scene in a hurry."

"That is - after he killed the deceased, Qiuchuan happened to see him."

"So he hit Akikawa with the weapon in a panic, and fled the scene without confirming whether he had killed Akikawa."

"This indirectly reflects that the force he used on Qiuchuan at that time should be the force he thought could kill Qiuchuan."

"Under such urgent circumstances, he absolutely had no way to properly dispose of the murder weapon, and the murderer must still be inside the theater."

"As long as we find the murder weapon and then check one by one with the people who don't have an alibi during the period of the deceased's death, we can identify the murderer."

Sera Masumi's words instantly gave everyone present great confidence.

Everyone looked at Sera Masumi with admiration.

In comparison, the great detective "Sleeping Kogoro" seems a little overshadowed.
-
"You are worthy of being a detective. You are really smart."

In the laundry room, Akikawa Sosuke listened to Sera Masumi's reasoning and couldn't help but sigh in his heart.

For Akikawa Sosuke.

Smart people are much easier to control than stupid people.

Because there is no need to worry that the other party will behave in a way that deviates from your expectations.

As long as you give the test question, the other party will definitely be able to give the only correct answer.

This is true for Conan and this is also true for Masumi Sera.

Akikawa Sosuke knew that he was not smart in this world where detectives were the protagonists.
That is why they are able to confidently exploit their own weaknesses and the detectives' confidence in their own reasoning abilities to precisely manipulate the thinking of intelligent people.

"Compared to what I said personally, what they deduced themselves is definitely more convincing."

Akikawa Sosuke whispered in his heart, and at the same time he knew that the time had come.

"I know that you, Mr. Nishihara, have covered up all the elements of your crime."

"Now, I'd like to ask the detectives to unpack the new motive, murder weapon, and alibi that I carefully prepared for Mr. Nishihara."

"Cough cough."

Akikawa Sosuke coughed in some pain.

Successfully attracted the attention of everyone in the room.
