The mastermind behind Conan

Handprints and butt prints that appear on the warehouse on the seventh floor.

Special windows for the conference room on the fourth floor: pivotal windows.

Gun marks and bullet casings appeared directly below the two windows.

Clues and ideas were quickly connected in Bai Shiwu's mind, forming a case reasoning with conclusive evidence.

In the conference room on the fourth floor.

"Officer Twilight!" exclaimed Takashi Matsuo, innocently.

"Ah, it's Mr. Matsuo, what's wrong?" Officer Twilight said.

"Can I go back first? I'll have other things to do later. And I've been proven to be a murderer, can't I?" said Takashi Matsuo with a smile.

"Well, indeed, Mr. Matsuo, you should go back today! It's a pity, if you leave now, you won't be able to hear Brother Shiraishi's wonderful reasoning!" Officer Twilight said regretfully.

"Hmph, Detective Shiraishi, just a young imp!" Matsuo Takashi said with a smile on his face, disdainful in his heart.

"Mr. Matsuo, please wait a minute!"

Just when Takashi Matsuo wanted to leave, Takeshi Shiraishi suddenly walked in slowly from outside the door.

"Brother Shiraishi, you're here!" Officer Twilight saw Shiraishi appear, and hurriedly asked, "You said you already know who the murderer is!?"

"Yes!" Shiraishi nodded.

"Mr. Detective Shiraishi, it's a pity, forgive me for not being able to stay and listen to your reasoning, I have something urgent to do later, so I'll go first!"

Matsuo Takashi smiled at Takeshi Shiraishi honestly and wanted to leave.

"No, Mr. Matsuo, you can't get out of here yet!" said Shiraishi playfully.

"Huh!?" the expression on Matsuo's face froze.

"Brother Shiraishi, what are you—" Officer Twilight wondered.

"I haven't started my reasoning show yet, you can't leave yet! Takeshi Shiraishi's voice became more and more playful.

"You... Mr. Detective Shiraishi, please! I'm really in a hurry right now, and I really don't have time to stay and listen to your reasoning!" Takashi Matsuo shouted loudly.

"Brother Shiraishi, Matsuo may really be in a hurry, anyway, his murder suspicion has been cleared, so let him go first!" Officer Twilight couldn't help but speak.

"No! because—you have to play the murderer!Mr. Matsuo!" Shiraishi Takeshi's eyes flashed, his waist was straight, and he was close to 1.9 meters tall and couldn't help but want to believe his words.

"Huh!?"

"Whah

"What!?"

"Wait, wait... Wait a minute, do you still think I'm a murderer!?" Matsuo Takashi said reluctantly.

"Aren't you a murderer?" asked Shiraishi playfully.

"Please, please think clearly, Detective Shiraishi, the murderer shot the victim in this conference room on the fourth floor! The silenced pistol used by the murderer is the evidence that it is not moving in this room!"

Matsuo Takashi's face gradually returned to normal, and then said: "And when the murder occurred, I was in the studio on the ninth floor to support the show. The only chance to come out is the four minutes when the film is played. "

"From the studio to the conference room, with the fastest speed, it takes more than six minutes to go back and forth, can I still commit murder!?"

In the end, Matsuo's tone became tougher, almost a shouting questioning tone.

"Hmph! It's really not good, I've run it myself!" Takeshi Shiraishi still said in a playful tone.

"Isn't that enough! You admit it yourself!" said Takashi Matsuo proudly.

"Yes, Brother Shiraishi, you have admitted it yourself!" Officer Twilight had nothing to say.

"So now, I can go, right? I don't want to play detective games with you as a notoriety detective!"

"But the room we are in is three floors further up, which is the warehouse on the seventh floor, and with the help of the windows there, the situation is different..."

Shiraishi Takeshi looked at Takashi Matsuo, who was quietly covered with cold sweat on his forehead, and then said:

"Because from the studio on the ninth floor, bypassing all the surveillance, it only takes two minutes to come to this warehouse, and it takes about four minutes to go back and forth. "

"What!?"

"That warehouse on the seventh floor?"

"About four minutes back and forth!?"

"Mr. Detective Shiraishi, what do you mean..."

Everyone was stunned for a moment, and they all became puzzled.

"Officer Twilight, please wait here, and let me show you the murderer's murderous modus operandi now!"

After Shiraishi finished speaking, he left the conference room, quickly ran to the warehouse on the seventh floor, and then dialed Officer Twilight's phone.

"First of all, on the windowsill of the warehouse, there are two palm prints and a rifle butt print, although it is not very clear, it seems that someone has deliberately destroyed it, but judging from the scattered appearance of dust, these marks have only been left for a long time. "

Takeshi Shiraishi used the phone to talk to Officer Twilight and the others on the fourth floor.

"Then, my reasoning show begins!" the corners of Shiraishi's mouth raised.

"Mr. Matsuo must have leaned out of the window and pointed his gun at the conference room on the third floor!"

Before Shiraishi Takeshi could finish his words, Officer Twilight suddenly interjected: "Wait a minute, Brother Shiraishi, do you think that the murderer shot from the window on the seventh floor, and then shot the victim in the head here? The window of the conference room is only a little open!"

"Ahhh!!h

"What!"

"There's a bomb!!"

"Brother Shiraishi !!"

Officer Twilight exclaimed, rushed to the window of the conference room, pushed it open, and looked upstairs.

"Smack!" sounded.

Takeshi Shiraishi withheld a pistol that he had borrowed from a TV crew.

A paint bullet filled with red paint landed on Officer Twilight's head, who had just poked his head out.

Then let go of the pistol and let the prop pistol fall down the open window into the meeting room.

"This is the murderer's method of killing!"

Takeshi Shiraishi said playfully: "The bullet marks and bullet casings on the ground directly below the window are the best evidence to prove my reasoning!"

"Let's go and confirm!" Officer Twilight yelled.

"Yes!"
