"After being killed, Beethoven's Moonlight Sonata is played, and from other sources, I think the murderers of Mr. Kawashima and Mr. Kuroiwa are the same person."

In the hall of the village office, Officer Twilight, who had gathered everyone together, continued with a nonsense, "And, judging from the blank time of the tape, Mr. Kuroiwa should have been killed a few minutes before he was discovered. ”

"That's around 6:30. In other words, everyone in this public hall at that time was suspicious. Officer Twilight looked at everyone with a serious gaze.

He continued, "And these people, apart from Mr. Mori, there is Mr. Ken Nishimoto, the first person who found the body, and Dr. Asai Makoto, who just performed the autopsy on us. ”

"The secretary of the murdered Kuroiwa village chief, Mr. Kazuaki Hirata, the daughter of the Kuroiwa village chief, Sister Kuroiwa Reiko, and her fiancé, Mr. Murasawa Monday."

"Also, Mr. Masato Shimizu, a candidate for election to the village head." Officer Twilight will be present and read out their names one by one.

"Wait, why did I become a suspect too? Joke! Hearing this law, Heiyan's eldest sister Heiyan Lingzi was directly dissatisfied.

"I've been being interrogated by you since about 6:20." Reiko Kuroiwa said loudly.

This group of policemen is too much, they don't have the ability to handle cases at all, and there are a lot of serious official words.

And in the face of such a woman, Officer Twilight was speechless. Indeed, for Sister Heiyan, their police are the best righteous people. Now that this kind of thing comes out, it is indeed unreasonable to make some trouble, and there is nothing to do.

At this time, Mori Goro, who was next to Officer Twilight, said, "Indeed, you can't commit a crime. ”

"It's the same with honest doctors." Hearing this, Lan next to him, who was leaning against the wall with Asai Honesty and Conan, said, "Because we've been together since six o'clock." ”

"Isn't that right, Conan?"

Ran, Lan also looked at Conan.

"Hmm."

Conan nodded.

"In that case, there are only four men left in the suspects." Officer Twilight groped his chin and fell into thought.

"This... Officer Twilight, I've been on the first floor since six o'clock. At this time, Secretary Hirata immediately stepped forward and said.

"Do you have any witnesses?"

Officer Twilight looked at him.

"You all know that, right?" Secretary Hirata turned to look at the few people present, "He was here when I was there." ”

"I'm sorry." Shimizu Masayan: "I went to the bathroom around half past six. ”

"So, Mr. Nishimoto." Officer Twilight looked at Ken Nishimoto, the hedgehog head, and said, "You were the first to find Mr. Kuroiwa's body. But what are you going to do in that kind of place? Doubtful. ”

"It was Black Rock who told me to come over." The hedgehog head Nishimoto Ken said with a panicked expression.

"Hmph, if he calls you over, you'll kill him, won't you?" Hearing this, Mori Goro snorted coldly and came over.

"No, it's not."

Ken Nishimoto denied.

"It's Qing Shui." At this time, Heiyan Lingzi said angrily: "The candidate for the village head election, if there is no my father's and Kawashima, then the position of the village chief will become Mr. Shimizu's." ”

Twilight and Mori's gaze was immediately drawn to it, and Masato Shimizu quarreled with Reiko Kuroiwa. Twilight doesn't stop them, because that's a motive.

"Conan, what are you looking at?"

At this time, Lan noticed that Conan looked like he was holding a notebook and looking at it seriously.

"I'm looking at the music scores left by the murderer at the scene of the murder." Conan looked at Landau, "I think it must be a secret message left by the murderer." ”

Lan leaned over, and Conan continued, "There may be some key to this ascending and descending mark. ”

"In the case of a piano, it means a black keyboard." Lan looked at it and said. Conan was stunned, because of his own lack of knowledge of music, so he didn't think about it.

"Right, keyboard?" Seeing that Conan seemed to see a little famous, Lan said again. Conan muttered, but didn't speak, and looked at it seriously.

At the same time, the quarrel between Reiko Kuroiwa and Shimizu Zhengrao not far away has not ended, but has intensified.

"Hurry up and arrest this killer for me. If you don't catch it, there will be another victim. Heiyan Lingzi said loudly, this woman is a little powerful, and the others can only watch from the side, trembling.

"Understand? You'll be next. Suddenly, Conan said this, and all eyes were drawn to him. Lan was a little strange, or taken aback. Because it's kind of like the words of a murderer.

Conan explained, "This code, if you know the trick, is very simple. Starting from the left side of the piano keyboard, put the English letters in order, and then write the message you want to convey in pinyin with notes on the score. ”

At this point, both Mori Goro and Officer Twilight looked at him, and their hearts were shocked by this reasoning. Conan, however, enjoyed the gaze.

He continued: "Based on this clue, the score at the scene of Mr. Kawashima's murder becomes, 'Understand? Next up is you. ’”

"You're amazing, Conan." After finishing this, he really looked at Lan and got a commendation. Officer Twilight grew more and more surprised.

Mori Goro hurriedly said, "So, what about the score that you wrote in blood just now?" ”

"Well...... "Conan looked at his book and said, "The resentment of sin is eliminated here." ”

As soon as these words came out, whether it was Sister Kuroiwa, Shimizu Masato, or Secretary Hirata, they all gasped, as if they thought of some secret past, and were taken aback.

"The resentment of sin, could it be ......" Secretary Hirata guessed, and Reiko Kuroiwa came out with the second half of the sentence, "The pianist who committed suicide by arson twelve years ago?" ”

"It's that guy, Keiji Aso, he's still alive." The hedgehog-headed Ken Nishimoto laughed horrifiedly.

"He's dead." At this time, the old policeman walked in and said, "The skull and tooth shape found at the fire scene at that time have also been compared, and it is absolutely true that it is their family." ”

"Everything was burned down at that time. All that remains is the sheet music in the fireproof safe. The old policeman remembered again.

The image of the fire twelve years ago came back to his mind.
