Conan looked at Katayama's smile and didn't seem surprised, he knew that Katayama would definitely be able to see the flaw as well.

Katayama looked at Conan's smile, and his heart was full of doubts, Gan Linniang, what are you laughing at!

He interrupted Officer Henggou's words only because Zorro had obviously discovered something, and he was afraid that the case would be closed so hastily, so he specifically said that the case was not so simple.

"Look, over there."

Conan pointed to the telephone on the floor, an old-fashioned landline with a handset connected by a signal cable and a dial key.

"This should also be on the empty seat of the bookcase, is there any problem?"

Dr. Asa looked at the phone, but he didn't see the door for a while, and he insisted that it was strange, probably because the phone was on the ground, but the bookcases had fallen down, and it was not strange that the phone had also fallen.

"If the phone really fell off the bookcase, why is its receiver still sitting securely on it?"

As soon as Conan's words came out, everyone realized the problem, indeed, the slightest vibration of this landline phone can cause the handset to loosen, let alone fall from it.

It is impossible to be so stable on the shelf, and the fuselage of the landline is also flat and neat on the ground.

In other words, it is only possible that the phone was originally on the ground...... But why put the phone on the floor of the room, and it was not in the corner, but in an empty seat near the professor's fall, with an open book on it.

It's so suspicious.

"In other words, someone deliberately arranged the room like this in order to cover up the call."

Katayama looked at the messy room, that is, this bookcase, these books scattered on the floor, all to cover up this unreasonable landline.

"Wait, you mean, it's murder?"

Dr. Asa quickly sensed the point, indeed, if someone had set up this scene, then it was obvious that this case could not have been an accident.

"You're trying to say it's a ...... Murder in a closed room! ”

Henggou police officer with homo peculiar ...... The nature of the case was determined by the police officer's unique experience of the case......

"Secret ...... Secret Room ......"

Professor Hirota's wife was a little speechless in surprise......

"Kill...... Murder ......"

Dr. Asa was also a little surprised, although he was not unfamiliar with the case, but the appearance of a murder case in front of his eyes would still make people uneasy.

"Case ...... Case. ”

Katayama scratched his head, he was just to cooperate with the formation, the secret room kills, he only met it not long ago, it is not strange.

"That's right, the locks in this room are all locked from the inside, if it's murder, it must be a murder in a closed room."

Officer Henggou pointed to the windows and ventilation windows, as well as the gates, which were still locked except for the doors that were pried open by Zorro.

"But, who the hell, who killed my husband!"

As the wife of Professor Hirota, it is inevitable that she will be emotional when she hears that her husband was actually killed, in short, she is anxious.

"Please calm down and think about who has visited your husband tonight."

Officer Henggou patted her on the shoulder and tried to calm her back.

"Except for the two gentlemen over there, my husband's students came to visit."

The woman pointed to Katayama and Asasa because Zoro and Yukifa were cats, and Conan and Ashbara were children, so it was impossible to be suspicious, at least in the eyes of the woman.

"Ah, we came to pick up the magnet today because a friend accidentally sent the wrong magnet to Professor Hirota........."

Afraid of being regarded as a murderer, Dr. Asa hurriedly explained to Yokogou, he didn't expect it, Gray Yuan happened to remember the matter of the magnetic sheet, and the professor was killed that night, which was indeed a coincidence.........

"Magnets........."

Officer Yokogou listened to Asasa's explanation and nodded thoughtfully.

"I think the magnets should be right next to the computer...... Ah, little mourning........."

Dr. Asa felt that it might not be convincing enough, so he pointed to the computer next to him, only to find that he had been using the computer to view the data on the magnets without knowing when he was already using the computer on his own.

"The magnetic sheet has been found, but unfortunately, the information inside seems to have been emptied...... In this case, the rest of the data on this computer has also been deleted......"

Gray Yuan stood on a chair in front of the computer, operating the computer.

"Who is this little girl?"

Henggou pointed to the gray plain, this behavior already belongs to the destruction site.

"Ahh

Dr. Asa quickly went over and took Ashbara away, and said embarrassedly to Yokozo.

"I'm sorry, but in fact, this is my relative's daughter, and I came with me, you said that we can't bring our children to kill people......"

"Ah, that's right."

Yokozo felt that there was some truth, so he crouched down and said to Gray Yuan and Conan.

"Listen to the children, you are not allowed to touch anything in this room, you take the kittens, and your grandfather and uncle to the next room."

"Eh, am I like grandpa...... I'm only 52 years old, eh......"

Hearing Officer Yokomizo's words, Dr. Asasa couldn't help but say, he is at most an uncle at his age.

"I'm only 21 years old......"

Katayama silently added, how can he be an older brother at his age.........

In the end, Katayama still hugged Zoro and the doctor hugged Snowflake and walked out of the room at the scene of the crime, followed by Conan and Gray Hara.

"You say, could it be those guys who did it?"

Conan lowered his voice and looked at Gray Yuan with a solemn expression, this case involved the magnetic tablets related to the black-clothed organization, and it was hard not to suspect that this was their handiwork.

"They really did it, this place has long been blown up."

Katayama was talking next to him, and the picture of Gin shooting Tokyo Tower with a machine gun appeared in his mind, which seemed to be a shot from the theater version, in short, Gin gave him the impression that his mouth was talking about being a low-key person, and he ended up being more high-profile than anyone else.

This includes, but is not limited to, blatantly parking a luxury car in front of a police station, having to blow up an undercover agent in someone else's car when you can shoot it with one shot, and shooting Tokyo Tower into a hornet's nest in front of everyone in Tokyo in a helicopter.........

All I can say is...... Well, the artist is bold.

"This ........."

Ash had thought it was possible, but she thought that maybe the organization would notice the disk, so she came over to destroy it.

But Katayama said so...... It's really not like gin's style......... If he had come, the professor would not have been lying on the ground like this...... It is estimated that it was a bullet hole in the head or was directly blown up.........

That guy is obviously very intelligent, but when it comes to things like cleaning up, it's surprisingly simple and rude.........
