Following Conan and the others, they came to the third floor of the mansion. Takizawa Yu saw a few people standing outside a room, knocking on the door while waiting to find Toyama Kazuha of Akio Shigematsu.

Soon after, Toyama and Ye who rushed over said pantingly, "I didn't find Mr. Shigematsu!"

"Then it will be troublesome. The keys in the house should be on the housekeeper. If he is not there, he can only hit the door!"

Without further delay, Hattori Heiji and Mouri Kogoro slammed into the door forcefully, and after several more consecutive hits, they slammed the door open.

Takizawa Yu and Haibara, who had been behind them, looked along the room they had smashed into and found a trail of blood on the ground.

"This is... someone killed someone here, and then dragged it into the cubicle of the room?" Hui Yuan looked at the bloodstain in confusion.

They are located on the outside of the room, and inside there is a cubicle for office use, and the blood stains point there.

After Conan and Hattori Heiji looked outside, they exchanged glances: "Go in and take a look."

As soon as they entered the inner room, several people saw the honest looking butler of the Mori Garden house, Akio Shigematsu leaned against the desk, covered in blood.

"Ahhhhh!!!"

Toyama Kazuha next to Hattori Heiji replaced the usual Moriran and screamed at super high decibels.

"Mr. Shigematsu?!"

Unexpectedly, the victim would be Akio Shigematsu. After Hattori Heiji hurried forward to check, he looked ugly and said, "We are late."

"Hattori, things are a bit weird." While Hattori Heiji inspected Shigematsu's body, Conan looked around again: "I didn't find the murder weapon in the room."

"Didn't find the murder weapon?"

Hattori Heiji got up and came to the window. After opening it, he saw Morilan standing outside the house. When Conan came up just now, she asked her to look at the window here, so she kept waiting below.

"Have you seen anyone escape from here?" Hattori Heiji said.

Shaking his head, Mao Lilan said, "No."

"That's weird."

After walking around the room with Conan, both of them frowned.

"When we came in, the door to the outside room was locked. Xiaolan kept watching from the window. No one escaped from there. There was no other way to leave the room..."

"That is, is this a murder in a secret room?" Mouri Kogoro said something beside him.

The two nodded, and then began to turn around the room again, trying to find some clues.

On the side, Kogoro Mori looked at Conan and Hattori Heiji who ignored him, running around the scene, and looked at Takizawa Yu and Haibara who were standing outside, and sighed with helplessness.

"Sure enough, it's better to yo."

Had it not been for the trouble with Takizawa Yuu and Aihara Ai, Maori Kogoro would have planned to take them to his own home.

"Aren't you going in?"

Ai Hara glanced at Yu Takizawa. She knew this guy's habit of going around the corpse every time a crime happened.

"Well, no need."

Takizawa Yu looked at a tall cabinet in the outer room: "I know who the murderer is."

After that, I walked over and stood in front of the cabinet, with no intention of going away at all.

When Takizawa Yu said this, he didn't mean to cover up at all, so all the people present heard what he said.

"Do you know who the murderer is?"

Conan and Hattori Heiji both looked disbelief.

The two of them came to the conclusion of the murder in the secret room after seeing the room where Akio Shigematsu's body was. They only knew the type of incident, the technique, the murderer, and even the murder weapon.

Takizawa Yu was just standing outside, how did he know who the murderer was?

Unless Takizawa Yu is the murderer, why can't he explain the speed of solving the crime in this instant?

"The door outside was locked when we came in, right?"

Takizawa Yu pointed to the door of the room that had been knocked open: "But it was only the door outside. The compartment door was not locked, was it?"

Conan and Hattori Heiji understood Takizawa Yu's words instantly.

They were all affected by the locked door outside, preconceived that the murder scene was a secret room, but there was an outside room outside that they hadn't checked.

"You mean the murderer is still in the room?"

Although the reaction was a little slower, Kogoro Mouri who still wanted to understand came over suddenly.

"Well, if we all entered that room just now, maybe the murderer would leave quietly." Takizawa Yuu nodded.

At this moment, other people in the mansion also rushed over. The sound of broken glass did not attract their attention. Although Toyama and Ye just talked to them when they were looking for Akio Shigematsu, they did not Take it to heart.

After hearing the screams of Yuanshan and Ye, they came to their room one after another.

After simply learning what happened here from Kogoro Moori, several people showed shocked expressions.

Looking at the Morien family present, Hattori Heiji suddenly said, "Where is Morien Kikuto?"

"Chrysanthemum?"

Mikio Morien looked around and found that there was no Kikuto Morien, and suddenly became uneasy.

From the explanation made by Kogoro Mori just now, he can also understand that the person who is not present at this time is likely to be the murderer.

Although the maids in the family are also possible, from the tone of Mouri Kogoro and Hattori Heiji just now, the suspicion of his son is the biggest.

"He should be here, right?"

Yu Takizawa gave up his position in front of the cabinet, and Ai Huihara stood behind Kogoro Mouri, while the knowing Hattori Heiji walked to the front of the cabinet and opened the cabinet directly.

"Chrysanthemum!"

After the cabinet was opened, Kikuto Morion stood there with a gloomy face, staring at Yu Takizawa who was standing behind Kogoro Moori.

Since Takizawa Yu stood in front of the cabinet, he had a bad feeling.Then, when Takizawa Yu suddenly said that he knew who the murderer was, the hunch became stronger. Several times he almost couldn't help pushing open the cabinet and let Takizawa Yu shut up.

Looking at the people outside the cabinet, Kikuto Morien walked out of the cabinet.

He had thought about pretending to be stupid, but at this time the knife used as a murder weapon and the clothes that he replaced when the blood splashed on him were on his body. He hadn't had time to deal with the marks on it, and it was useless to explain it.

It's not that he didn't want to deal with it cleanly, but that he didn't expect Mao Lilan to be watching all the time, so that he could not find a chance to throw things out.

According to his original plan, even if there are people standing outside the mansion, he can quietly walk out of the cabinet after other people find the body in the compartment, mix in the crowd and pretend to be like he has just arrived, and look for it later. Opportunity to deal with the evidence.

But now it's obviously not working.
