"Yes, Nishimoto Ken was indeed killed." Xia Ri glanced at the closed music score and continued, "And don't you find it strange? Suicide books are meant to be read by people. For Nishimoto Ken, suicide means liberation. Since he has been relieved, why did he have to write it down with a secret code?"

"Well... what you said makes sense..." Officer Memu nodded in agreement, but another doubt arose in his heart.

"But since he killed him, why did the murderer make such a low-level mistake?"

"I think it was because of some things or some people who suddenly caught him off guard." Xia Riyi said with some reason, "It must be that the murderer encountered another emergency after the murder, which made him have to stop the aftermath and leave here immediately."

"Emergency!? Could it be..."

Officer Memu's eyes lit up. He first thought of Hirata Kazuaki, and then thought of Murazawa Shuimi who fainted in the piano room.

Xia Ri took a deep breath and understood in her heart that it was time to express her guess...

However, before Xia Ri had time to speak, he suddenly saw a police officer from the forensic team running in with an object in his hand.

"Meguro Police Department! We found this thing on the floor of the piano room!"

Xia Ri looked into the policeman's hand and saw him holding a tube-shaped thing. Unfortunately, after watching for a long time, Xia Ri couldn't see what it was.

"What is this?" Officer Meguchi asked.

The police officer of the forensic team explained: "This is a tuning tool for piano. We found Murasawa Chuichi's fingerprint on it and asked Miss Kuroi Iwara Reiko, proving that this tuner is indeed Murasawa's item."

"Tunner?" Officer Meguchi was stunned at first, then nodded with understanding. "I remember Murazawa said that he was a student of the music school in college, so it was not surprising that he had such a thing, but what did he want to do when he brought it here?"

Kogoro suddenly showed a look of enlightenment on his face.

"I understand!" Kogoro shouted loudly, "The murderer must be Kazuaki Hirata! After killing Nishimoto, he was trying to perfect his methods and disguise Nishimoto's death as suicide, but Murazawa broke in at this time. With no choice, Kazua Hirata could only knock Murazawa out!"

"It seems that this is the only possibility!" Officer Memu touched his chin and frowned, "But what exactly did Murazawa do when he went there? And if he just knocked Murazawa down, wouldn't Hirata be very troublesome when Murazawa wakes up and faces his identification?"

"Well..." Kogoro's eyes turned and he said, "The reason why Murazawa went to the piano room is probably because he wanted to debug that piano!"

"Maybe Murazawa heard about Kuroiya Takiji's order to ask Hirada Kazuaki to destroy the piano. As a student of the music school, Murazawa should have wanted to provide the final maintenance for the piano before it is destroyed, and it can also be regarded as remembering the former deceased."

"But I didn't expect that after he came here, he undoubtedly broke Hirata Kazuaki's secret, so he was attacked by him!"

"As for why Hirata did not kill Murazawa Shuimai, but just knocked him out... I think it was because he had knocked Murazawa Shuimai, and before he could do it, he was seen by Xia Ri and Conan who suddenly broke in. Because he was shocked, he would go downstairs and jump out of the window and escape!"

"So that's it, everything will be explained!" Officer Memu was overjoyed, "It seems that the breakthrough should still be on Kazua Hirata. As long as he admits, the case can be closed!"

Kogoro laughed and said proudly: "That's right! As long as my famous detective Kogoro Mori takes action, no matter what case is in my eyes, it will be as simple as eating and drinking water! Haha..."

"You really are!" Officer Memu was happy and patted Kogoro on the back with a smile, "Okay, Hirata Kazuaki is now detained in the Yueying Island Office. Since that's the case, let's go and interrogate him together to see what he has to say now!"

Looking at the backs of Officer Meguru and Kogoro and others leaving together, Xia Ri did not stop them, but stood there and remained silent for a few seconds, and followed.

Although he had already confirmed that Asai Nashi was the murderer, now that he had already shaken his heart after hearing Kogoro's reasoning.

What if the truth of the truth really has nothing to do with Asai Narimi, and everything was just caused by Kazua Hirata? Then, wouldn’t he betrayed the good man now?

Forget it, let's wait a little longer, let's hear what Hirata Kazuya will say first...

...

In an office on the first floor of the Yueying Island Office, Kazuna Hirata was ashamed and sat on a chair, while his hands were handcuffed to the back of the chair.

In front of him, in addition to the two policemen, Officer Memu and Mikako Sato, after Officer Memu's permission, Xia Ri and Kogoro also moved a chair and sat aside to listen.

Through the lights in the corridor, you can vaguely see someone shaking outside the office. Xia Yan looked into the crack of the door under the door. At this time, you can clearly see a pair of small-sized sneakers, constantly wandering outside the door.

The owner of this pair of shoes is Conan. Xia Ri felt funny and knew that Conan would definitely not be able to control his strong curiosity at this time and was hiding there to eavesdrop on the movements in the room.

Originally, Conan wanted to sneak into the office, but unfortunately his little move was discovered by Kogoro. After being hit by Kogoro's angry iron fist, Conan had to hold his swollen head and reluctantly leave the room.

Now it seems, hehe, this little devil is still not giving up...

On the side, Mikako Sato coughed lightly and secretly glanced at Xia Ri with her eyes.

Now all the clues point to Hirata Kazunaga. His identity as a murderer is a foregone conclusion, and Hirata Kazunaga was captured by himself. From this point of view, it seems that he has won the bet!

Humph, after Hirata Kazuaki confesses his guilt, I must let you kneel down and admit your mistake for the previous incident!

Thinking of the happy scene, Sato Mikako's mouth couldn't help but start to curl up slightly.

Humph, wait!!

At this time, Officer Memu slapped the table, which not only scared Hirada Kazuaki, but also focused all the attention of Kazuki and Sato Mikako.

"Haida! Even if you don't admit that you are the murderer, you can't change anything now. At this point, I advise you to tell me what happened all the time!"
