In Conan, people have a brain option system

"It's so strange that the camera didn't capture it. Could it be that there is some way to avoid the camera?"

The female detective responsible for checking the surveillance video said with a confused look.

"No, there is no such path."

The staff of Kosen-an on the side flatly denied it.

"Then it's simple. The murderer is either among the staff or lives on the first floor."

Sera Masumi said.

There are only two rooms for guests on the first floor of Kosenan.

Both rooms are extremely luxurious, suites with private open-air hot springs.

The Okamura Police Department further questioned the criminal police officer responsible for searching the room on the first floor, but he said that nothing suspicious was found.

"Could it be that you didn't search carefully and missed it?"

Okamura Police Department asked, looking at the subordinate police officer.

"Probably not. I also asked Kosenan specifically to retrieve the information registered by the residents on the first floor when they checked in."

"I compared the information on the occupants of the rooms on the first floor recorded above, and they are all consistent with the residents in the rooms, so the deceased is definitely not a resident of these two rooms."

said the detective in charge of investigating the room on the first floor.

"Could it be said that the deceased was a staff member of Guquan Nunnery?"

Okamura Police Department added, looked at the staff on the side and asked:

"Have you noticed that any of your colleagues suddenly disappeared or were late?"

The staff member went to confirm, and when he came back, he said that all the staff were there.

“This is weird”

Okamura Police Department added that he was confused, then looked at the policeman in the forensics section and said:

"Go to the two rooms on the first floor and do a luminol blood test. It is impossible to dismember a body without leaving traces."

The police officers from the forensics department agreed, knocked on the doors of the two rooms, and then walked in with tools.

Conan wandered in the corridor of the accommodation area on the first floor.

He discovered that in addition to the two rooms for guests, there was another room in the accommodation area on the first floor.

"I would like to ask, what is this room used for?"

Conan asked looking at the staff member of Kosen Temple.

"Ah, this is the boss's personal room and will not be provided to tourists."

the staff member answered.

"So that's it."

Okamura Police Department added, walked to the door of the room and knocked on the door.

After knocking on the door for a long time, the door was opened.

Then, Conan and the Okamura Police Department met with Kunio Koizumi, the owner of Kosenan, who they had met yesterday.

Appearing with Kunio Koizumi, there was also the strong smell of alcohol hitting his face.

"Speaking of which, when the case occurred yesterday, Mr. Koizumi came out to check on the situation."

"But today, Mr. Koizumi has been staying in the room."

Conan put on an innocent look, looked at the somewhat listless Koizumi Kunio and smiled.

His words immediately aroused the suspicion of Sera Masumi and Okamura Police Department.

Both of them looked towards Kunizumi Kunio.

"That's because I drank too late last night, so I was hungover and never woke up."

"If you hadn't knocked on the door just now, I probably would have stayed asleep."

Koizumi Kunio said with a tired face.

And his statement did not convince those present.

"Excuse me, Mr. Koizumi, we need to search your room."

Police officer Okamura walked into Kunio Koizumi's room first, while Masumi Sera and Conan followed closely.

Then everyone discovered that Koizumi Kunio's room was completely different from other rooms rented to guests that lacked the atmosphere of life.

Koizumi Kunio's room looks no different from an ordinary house.

The furniture and appliances in the room are all available, including washing machines, refrigerators, computers, and even microwave ovens and coffee machines.

At first glance, there is nothing strange about Kunio Koizumi's room.

But Sera Masumi keenly noticed that there were water glasses filled with liquid on the desk with the computer and on the dining table in the next room.

"There is only Kunio Koizumi in this room, but there are two water glasses in use."

Sera Masumi noticed something was wrong, so she picked up the cup and smelled it.

After she put down the cup, she came to the sink again, and after seeing two toothbrushes over there, she confirmed her suspicion.

She walked back to the living room and said to Kunio Koizumi:

"Mr. Koizumi, do you live here alone?"

"My friends come over to stay sometimes." Kunio Koizumi replied.

"Do you have any friends who come over often to stay?"

"No."

"You're lying, Mr. Koizumi."

Sera Masumi heard the words and spoke directly.

"I saw two toothbrushes placed in front of your sink. If someone doesn't come over to borrow them from time to time, you definitely wouldn't place other people's toothbrushes, right?"

"Moreover, the cup on the desk and the cup on the dining table here contain the same tea."

"If one of these cups was not prepared by Mr. Koizumi for the friend who stayed yesterday, then you poured yourself two cups to drink the same tea and didn't finish it, right?"

"Well, that's not surprising, right? I just forgot that there was a cup of tea over there."

Koizumi Kunio hesitated for a moment, then spoke.

"There is nothing wrong with your statement, but if so, the surveillance camera must not have captured the scene of your friend entering Kosen-an."

Sera Masumi said, then turned to look at the Okamura Police Department.

The Okamura Police Department also immediately understood and quickly summoned the police from the Forensic Division, who used luminol reagents to conduct a luminol blood test on the inside of Kunio Koizumi's room.

After seeing this scene, Kunio Koizumi's face began to look a little ugly.

And his reaction did not escape Sera Masumi's eyes.

A few moments.

Luminol blood test results revealed.

After the police from the Forensic Division sprayed luminol reagent in Kunio Koizumi's bathroom, they discovered that a large area of ​​luminol reaction had occurred on the bathtub, floor and walls of the bathroom.

"Mr. Koizumi, you were the one who dismembered the deceased, right? It was in this bathroom."

Sera Masumi stared at Koizumi Kunio and asked.

Kunio Koizumi did not admit it, but fell silent.

After Conan carefully observed Kunio Koizumi's room, his eyes finally fell on the laptop on the desk.

After a moment, Conan's heart suddenly moved, and then he said loudly:

"I thought of it!"

Everyone present was startled by Conan's roar, and then looked towards Conan.

Conan, who realized that he was a little too excited, pointed to the computer over there with some embarrassment.

Sera Masumi looked in the direction of Conan's finger.

Soon, her unique pair of dark green eyes suddenly widened.

"So that's it."

"The posture of the deceased that the murderer wanted to hide by dismembering the body was exactly the posture of using a computer!"

After hearing Sera Masumi's words, Kunio Koizumi's cheeks lost color in an instant.
