Hearing Gao Yuan's question, Kashiwagi Shion and the three of them nodded seriously in unison. Among them, Usami Chiyo was the first to say:

"Yes. We were about to go on stage at that time, but the manager was so excited that he spilled the coffee he was drinking on his clothes. Then he borrowed the locker key from me and asked me to change clothes... wait until our performance was over.

, when I returned to the lounge, I found the key on the coffee table in the lounge, but the agent was nowhere to be seen."

"That's right... Later, after Shiyin and Chiyo temporarily left the lounge, I saw the manager come back a little tired... and then..."

Izumo Yukino added, and as he spoke, his emotions were about to break down. Fortunately, Kashiwagi Shion on the side quickly comforted him.

In this regard, Gao Yuan did not let Izumo Yukino continue talking, but asked:

"When you went on stage to perform, he didn't come to watch?"

Hearing this question, Kashiwagi Shion and the other two were suddenly stunned for a moment. They looked at each other involuntarily, and then they all shook their heads. Finally, Usami Chiyo spoke up:

"It seems...I really didn't see it..."

"At that time, we thought the agent would be watching us at the entrance to the backstage, but he was not there either..."

Kashiwagi Shiyin also said.

After receiving such an answer, Gao Yuan immediately became convinced of what he had sensed before, the strangeness in this whole matter——

It is a bit unreasonable for a group under my own name to participate in such an important performance, but the manager was not present at the time -

In other words, from the time the three of them prepared to perform on stage until the end of the performance, the whereabouts of the deceased Mr. Sakano seemed to be unknown!

But, what happened that prevented Mr. Sakano from even watching their performance?

Was it planned in advance or was it an unexpected incident?

Thinking like this, Gao Yuan began to think about the possibilities. At the same time, he also tried to put himself into Mr. Sakano at that time and consider what might have happened at that time——

Although it is unclear what this has to do with Mr. Banno's murder, so far, this is the only point Gao Yuan can try to investigate.

So, Gao Yuan began to pace back and forth in the dressing room. Considering that Mr. Sakano should change clothes here first, he tried to imagine the scene at that time——

Mr. Sakano borrowed the key from Usami Chiyo, opened the cabinet, took out the spare clothes, and then changed them...

While thinking about it, Gao Yuan walked to the cabinet and paused for a moment. Then when he was about to leave the dressing room, Gao Yuan's eyes suddenly turned to the full-length mirror on the wall on the other side——

There is a mirror. When changing into a suit, in order to ensure that you are dressed appropriately, you should still go to the mirror to tidy up, right?

Thinking like this, Gao Yuan turned around and walked to the full-length mirror embedded in the wall, and tried to imitate it, simply adjusting the collar of his windbreaker——

But at this moment, Gao Yuan suddenly noticed that there was a very obvious fingerprint on the mirror surface, roughly at the position of his eyes. It seemed that not long ago, someone had put his palm on the mirror surface.

In this regard, Gao Yuan suddenly seemed to have thought of something. Likewise, he also stretched out his hand. With his gloved right hand, he stretched out his index finger and lightly touched the mirror. Then his eyes were close to the mirror and he carefully observed his right hand.

Fingers and their images in the mirror——

Through careful observation, Gao Yuan discovered that the fingers and the mirror image were stuck together!

Upon seeing this, Gao Yuan immediately widened his eyes, and his originally clueless thoughts suddenly exploded at this moment.

Then, he said to the curious girls behind him:

"There should be an escape plan for this floor in the corridor, right? Can any of you take a picture of it for me with your mobile phone?"

Hearing this, Izumo Yukino immediately volunteered and agreed——

"I go!"

Probably sensing that Takato seemed to have an idea, Yukino Izumo couldn't help but look a little excited as to whether he could solve the case within an hour.

After a while, Izumo Yukino took his mobile phone and showed the floor plan of this floor to Gao Yuan.

"Mr. Detective..."

Izumo Yukino said, handing the phone to Gao Yuan, and Gao Yuan also took the phone, carefully looked at the floor plan of this floor, and quickly found the dressing room in the picture where he and others are now.

location, then find the wall where the mirror is embedded, and follow the path to find the room behind the wall and the road leading to that room——

"You actually have to go around this corridor and use another entrance to get there!"

They seemed to be words of doubt, but there was a hint of surprise in Gao Yuan's tone - at this moment, Gao Yuan seemed to be able to figure out the truth of the whole matter.

So, Gao Yuan returned the phone to Yun Xuenai, took out his phone, came to the mirror again, stretched out his finger and pointed it on the mirror, used the photography mode, and carefully moved his finger and the position of his finger in the mirror.

I took a photo of the mirror image, and also took a careful photo of the handprint on the mirror.

After that, Gao Yuan, who did not turn off the photography mode, came to Tie Zhuyu, handed the phone into her hand, whispered a few words in her ear, then looked at the other people and said loudly:

"I think I roughly understand what's going on... However, in order to investigate further, we have to go to the room behind this wall first!"

As he spoke, Gao Yuan pointed to the wall with a mirror embedded in it.

Regarding this, Kashiwagi Shion and the others were a little confused, but they couldn't help but nodded, and then Izumo Yukino asked:

"So, Mr. Detective asked me to take a topographical map to find the way to that room?"

"That's right!"

Gao Yuan nodded and said:

"Without further ado, let's get there quickly! After all, the road is still quite far!"

So, the three of them nodded and were about to follow Gao Yuan out of the locker room. However, Matsunaga Shion, who was following Tie Zhuyu, saw Tie Zhuyu holding Gao Yuan's mobile phone and filming the scene at the moment, but he did not want to take action.

He looked uneasy and said:

"Zhu Yu, should we... also follow?"

In response, Tie Zhuyu smiled lightly, shook his head, and whispered:

"No, we'll just watch from here!"

As soon as he finished speaking, he saw Gao Yuan leading the three of them out of the locker room. However, he saw Gao Yuan suddenly turned around and ran quickly towards the wall with a mirror embedded in it. Relying on the momentum of running, he raised his foot.

Put it directly under the mirror.

Then, the lower half of the mirror shattered, revealing the scene behind the mirror——

I saw that behind this mirror was not a wall, but a hollow passage! It could lead directly to the room behind this wall!

As the lower half of the mirror shattered, Gao Yuan directly removed the upper half of the mirror that was originally embedded in the wall and gently put it aside——

At the same time, as the entire mirror was removed, a middle-aged man holding a camera and a surprised look appeared behind the mirror in front of everyone.

In response, when he saw the other party's appearance, Gao Yuan, without any surprise, without saying a word, kicked the other party to the ground, and stepped on the other party firmly, preventing him from getting up——
