After some investigation, Bai yanzhenyu found the same scratch on the handrail of Mrs. Meifang's room on the window edge of the French window. Conan also found some red liquid on the piano. In addition, he didn't find any other clues for the time being.

Maori Kogoro went to President Cana and sighed, "President Cana, it should be you who killed Mr. Tianma."

"What's the matter? It's not me at all. I was sitting in the lounge in the compartment just now."

President Gana was sweating and explained, "after coming here, Tianma ignored my existence and went to the piano. I had no choice but to find a chair in the compartment. As a result, I suddenly heard a loud noise and a scream. When I looked over, I found that he had died there."

Maori xiaowulang touched his chin and said suspiciously, "at that time, there were only two of you here. The rest of us were all in the hall on the first floor. Who else could there be but you?"

"Yes," Gana Xiushu agreed with Maori Kogoro and said bitterly, "brother, how can you do such a thing?"

The president of Canada glared at his brother suspected of falling into a well and retorted angrily, "I said I didn't kill people!"

Jia Na Xiushu looked at his brother angrily and asked, "in fact, before that, you opposed my decision to sign Gerald alone. Just now you know the fact that Mr. Tianma and his sister-in-law had been in contact before. You were obviously stimulated, so you killed Mr. Tianma. Do you still want to argue?"

"You!" President Cana looked at his brother angrily, but he couldn't refute the reasoning just made by Maori Kogoro. After all, he was the most suspect who stayed here at that time.

"It seems that the Canadian family is really going to be over this time. What a pity, president."

Gao Leng chuckled with indifference, glanced at the silent Mrs. Meifang, and said with meaning: "if something like this happens, I don't know who will inherit the next Cana entertainment group."

Bai Yan Zhenyu didn't jump to a conclusion and asked, "President Cana, did you see the murderer?"

"No," President Gana shook his head and replied, "when I arrived, there was no one else in the room."

At this time, Conan seemed to find something and suddenly asked President Cana, "uncle, when Mrs. Meifang took us to visit just now, the piano cover seemed to be closed. Did Mr. Gerald open it?"

After hearing Conan's question, the sad Mr. Michelle replied for president gagana: "no, according to the size of this house, even if the piano cover is not opened, the sound will be very loud, so Gerald won't open it."

However, after Conan's reminder, President Cana recalled the situation when they came into the room and added: "I remember. In fact, when we came to this room, the piano cover had been opened."

After listening, Maori xiaowulang turned to look at the indoor situation after opening the piano cover and guessed: "so, the murderer opened the piano cover in advance in order to block his sight and make people here can't see him."

Mrs. Meifang seemed to be frightened by the bloody scene. She held president Gana's arm tightly and asked, "Mr. Maori, I believe Shanze is not the murderer. Do you think the murderer may be the person who attacked me before?"

"Well... It's possible."

Maori Kogoro nodded approvingly and reasoned: "after the man ran away, he was likely to hide here. As a result, he met Mr. Tianma who came to play the piano, so he killed Mr. Tianma with a knight's sword, and then ran away."

In order to prevent the possible murderer from continuing to hurt people, Maori Kogoro asked everyone to stay in the piano room and wait for the arrival of the police.

Soon after, Mumu police department led a team to the scene. After listening to the story of Maori Kogoro, they began to investigate the scene.

The Mumu police department looked around the room and analyzed: "there is only the door in front of the lounge at the entrance and exit of this room. Although the floor to ceiling window at the back is also possible, there is a cliff deep sea below. If people jump down from here, they will definitely fall on the stone below. Therefore, the murderer should not have escaped."

President Cana heard what the Mumu Police Department said, worried that the crime would fall on his head, and quickly distinguished: "Mr. policeman, as long as there is a rope, it is possible to escape from the French window."

"It's not impossible, but don't forget that you came here from the compartment at that time. Can the killer really escape in such a short time?"

Mumu police department also agreed with President Cana, but insisted on his previous analysis, which made president Cana speechless.

At this time, the police have also done the corresponding marking work. After removing Gerald's body and the Knight Sword, they began the on-site investigation.

Baiyan Zhenyu and Conan followed the forensics personnel and found a dent left by the knight's sword on the floor marked with the location of Gerald's body. In the shape of the dent, the knight's sword seemed to fall vertically on the floor from the air.

"Fall vertically?!"

Baiyan Zhenyu and Conan were worried. They looked up at the crystal lamp hanging above and found that the position of the small crystal lamp above their head was obviously much higher than the surrounding large crystal lamp. It was obvious that their height was adjusted through the control mechanism.

"Do you mean..."

Conan seemed to want to understand something. He hurriedly climbed up the ladder to the corridor on the second floor of the house. After investigating it, he found new clues - the same scratch on the railing and the box containing the score of the red dream song that Gerald gave to Mrs. Meifang in the past ten years.

After Conan came down from the corridor on the second floor, Baiyan Zhenyu quickly asked, "Conan, what did you find?"

Conan nodded and said confidently, "I probably know who the murderer is, but I still need a key evidence. Brother Zhenyu, please tell the police later and ask them to help find something."

Baiyan Zhenyu blinked and asked curiously, "what are you looking for?"

Conan reached Baiyan Zhenyu's ear and whispered, "what I'm looking for is a Beethoven sculpture. If I'm right, it should be in the sea water under Mrs. Meifang's window."

"You mean, the murderer is that man?"

After listening to Conan's words, Bai yanzhenyu narrowed his eyes slightly and was surprised. Then he asked officer Gaomu for help and asked him to arrange someone to go to the seaside to find the Beethoven sculpture Conan needed.
