Research Institute, third underground floor, office.

"What are you going to do?"

Miyano Shiho held a coffee cup and looked at Sakaki Makoto who was walking back and forth in the room with a smile on her face.

Seeing Sakaki Makoto's frustrated look, she felt secretly delighted.

The appearance of the family letter immediately turned the question of whether Kudo Shinichi was dead from undetermined into a mystery.

Originally, Miyano Shiho only needed to operate behind the scenes to make Kudo Shinichi completely "dead" on the organization's list.

But now...

Kento Naoi and Ryohei Kimura are both witnesses, and Gin will not give up until the matter of the envelope is fully revealed.

Sakaki Makoto walked around the room a few times, feeling a little unhappy.

If Gin finds out that Kudo Shinichi is not dead, the organization will send people to monitor those who have close contact with him day and night, and Mouri Ran will be the first to bear the brunt.

Mao Lilan was under surveillance, and Conan, who was following her, was very likely to be exposed....

Once Conan is exposed, Miyano Shiho's research results will be known to Gin and others.

By then...

Sakaki Makoto scratched his head anxiously.

How to remove fingerprints...

Anhydrous alcohol, gauze...

Methods of removing fingerprints flashed through my mind.

Suddenly, Sakaki Makoto had a flash of inspiration and said:

"Shiho, do you have an eraser?"

"have."

Miyano Shiho opened the drawer and took out a pink eraser:

"You don't want to erase fingerprints with an eraser."

"It will wipe off everyone else's fingerprints as well."

"By then there won't be anyone's fingerprints on the letter, and it will only arouse Gin's suspicion."

Sakaki Makoto smiled:

"Don't worry, fingerprints can be forged..."

Holding the eraser, Makoto Sakaki began to write quickly.

Carefully use the eraser to erase every corner of the paper, inside and outside, no matter how big or small.

Finally, Makoto Sakaki returned the eraser to Miyano Shiho and hurried out the door with the envelope.

There is no time to lose. Once Gin returns to the institute, he will definitely ask for a letter. I have to forge the fingerprints before he comes back.

"Hello!"

Seeing that he was about to leave, Miyano Shiho stood up suddenly:

"you...."

“When will you return my card?”

Sakaki Makoto waved his hand without even turning his head:

"Next date..."

His steps suddenly stopped and his voice ceased.

Sakaki Makoto slowly turned his head...

Miyano Shiho's eyes were wide open and her face was flushed.

"I...I don't have much time to go out."

"Remember to tell me in advance."

Although Miyano Shiho was under surveillance when she went out, she could get a pass easily by saying she was going to see Miyano Akemi.

But Miyano Akemi's watcher...

Isn't it Sakaki Makoto?

............

Boom boom!

"Open the door!"

Makoto Sakaki stood in the corridor of the Mori Detective Agency and pounded on the door.

Soon, the door opened and Mouri Ran and Conan appeared.

"Mr. Sakaki Makoto?"

Mao Lilan said with some surprise:

"Why are you here?"

"What's the matter?"

Sakaki Makoto was in a hurry, so without saying a word he stuffed the letter into Mouri Ran's hand, rubbed it a few times, and then rushed out of the corridor.

Behind him, Conan looked at him in confusion, completely unaware of what was going on.

After coming out of the Mori Detective Agency, Sakaki Makoto took out his cell phone and called Megure Juzo.

beep...

beep...

"It's Brother Sakaki Makoto!"

"It's so late..."

"I'm responsible for distributing the address list of post office personnel at Beika-cho 2-chome!"

Sakaki Makoto looked at the time and said anxiously:

"quick!"

Megure Juzo sat in the office of the Investigation Division 1, feeling confused:

"A list of post office personnel?"

"Brother Sakaki, what do you want this for?"

"I'll explain it to you later. Send the information to my phone within ten minutes!"

Sakaki Makoto hung up the phone directly.

Hearing the busy tone coming from the microphone, Megure Jusan was stunned for a moment, then called Takagi Wataru in.

Since the surprise inspection by the Metropolitan Police Department, Gin has returned to the institute before 11 o'clock every day to ensure its safety.

It is now 10:03. Without a suitable excuse, Sakaki Makoto must forge the fingerprints within an hour and rush back to the institute.

In less than five minutes, the notification tone for new text messages rang.

Sakaki Makoto read the text message from Megure Jusan, opened the door and got into the car, then said to Naoi Kento:

"Let's go to 4-chome!"

Kento Naoi started the car.

He still doesn't know what Sakaki Makoto is busy with.

As the younger brother, his duty was just to drive.

At 10:24, the car stopped outside a U-shaped apartment building.

According to the text message, Makoto Sakaki went up to the second floor and knocked on the door of Hasegawa.

The sound of a television rang through the house, and the family was watching the evening news.

"Recently, the Metropolitan Police Department cracked a horrific serial murder case, but the Metropolitan Police Department remained silent about the people who assisted in the case..."

Squeak.

A woman in house clothes opened the door.

"Ah...you are..."

"Does Hasegawa Shun live here?"

The woman nodded:

"He is my husband, please..."

"Sakaki Makoto."

Sakaki Makoto took off his sunglasses and shook them. The woman immediately covered her mouth:
