Wei sneered and said, "A murderer who kills two people in a row will regret it? Does he think that other people's IQs are twenty-five?"

"Sister?" Lan looked back at Yui suspiciously.

Wei said lightly: "From a psychological point of view, if a murderer misses and kills a person for various reasons, it is possible to regret it, but if he kills two people in a row, he will definitely not, because he has enough time to accept all this, so ......"

"This is murder!" everyone understood.

Officer Twilight also said next to him: "Yes, Ken Nishimoto's suicide note left some clues on it, it is said that he killed people because five people made mistakes and didn't want to be exposed, these five people are Mr. Kameyama who died two years ago, Mr. Kawashima and Mr. Kuroiwa who were killed this time, Ken Nishimoto who hanged himself, and, Keiji Aso who set fire to ** twelve years ago!"

"Huh, how could you get involved with Keiji Aso?"

"I don't know about this yet. Officer Twilight said.

Conan said, "I saw a suspect?"

"What?" said Officer Twilight, stunned.

Conan said, "I saw two people in the piano room, one was Mr. Murasawa who had fallen, and the other had escaped through a window. ”

"What, don't say it sooner!"

"Peng!", Conan had a big bag on his head again.

"That's it!" Yui touched his chin and said, "Conan, what did you just ask the police uncle?

Conan muttered as he recounted the news he had just gotten,

Wei touched his chin and thought about it, but he really didn't know how to reason, so he simply let it go, well, anyway, the murderer didn't just become Shisang!

Thinking of the possible actions that stumbled on Asai Narumi for two days in a row, Yui couldn't help but smile proudly.

Sure that the old policeman couldn't find the sheet music for a while, the group came to the piano room, where Asai Narumi was treating Mr. Murasawa for treatment.

"Hasn't Mr. Murasawa regained consciousness yet?" asked Officer Twilight.

"Yes. Asai said, "I guess it's a slight concussion!"

Officer Twilight turned his head to look at Reiko Kuroiwa, who was faintly in tears next to him, and said, "It's just, Miss Kuroiwa, why did Mr. Murasawa come here at this time!"

"How do I know!" Reiko Kuroiwa roared directly.

Yes, it's better not to be knowledgeable with women, especially women who are in a hurry to get angry.

Officer Twilight was directly defeated.

Conan saw something next to him, it was something that Mr. Murasawa was carrying, and he couldn't help but lean over and pick it up and look at it, not wanting to directly anger Reiko Kuroiwa, who was on fire.

Reiko Kuroiwa snatched the thing and shouted, "Don't mess with Monday's things, okay?"

"Uh...... Hey!" Seeing that Reiko Kuroiwa looked like he was about to go berserk, Conan muttered in response.

Officer Twilight also saw the thing and asked suspiciously, "What is this?"

"I don't know, but I'll take this with me wherever I go on Monday!"

Just because Officer Twilight and Reiko Kuroiwa don't recognize it doesn't mean that others don't know what it is.

Conan could already see what it was.

It's something that few people usually know, but Conan just happened to know what it was—that was the tool for tuning the piano, the tuning hammer.

Yui also recognized it, she frowned slightly, and suddenly remembered one thing, when she played the piano before, the sound of the piano was very accurate! A piano that has not been played for twelve years should not be so accurate, right?

In this way, the reason why this Murasawa appeared here on Monday is ......

At this moment, Officer Twilight said, "Okay, gather all the suspects at the town office!"

"Yes!" the dragon clad snorted and turned to leave.

Officer Twilight walked out with the others.

Lan was also about to follow, turned his head to look, but couldn't help but be stunned.

"Huh, sister, what are you doing with Conan, we're going to the town office!" Lan watched Yui and Conan come to the piano together, knocking back and forth, knocking there, and exclaimed with a puzzled expression.

Only carefully searched back and forth.

Conan said, "The figure who escaped before seems to be looking for something here, so, ah, I found it!"

Lan was stunned for a moment, ran over, looked at this dark grid curiously, reached out and touched it, and said with a curious face: "This is ...... It's fun!"

But instead of looking at the dark grid, she saw something else.

"What is this?" I saw that under the slightly gloomy piano, there was something powdery.

"Conan, come and see!"

Conan also saw the powdery stuff, reached out and dipped it, sniffed, and froze, "This is ...... Drugs!"

"Drugs?" Lan looked back at the powder.

Yuiya looked at the powder in surprise, sat cross-legged on the floor, thought for a while, and suddenly laughed thoughtfully, and said, "Conan, do you remember what you just said? You just told me that Hirata and Mr. Kawashima often sneak around here in the middle of the night, and what place do you think is safer than a place with a horror piano? ”

"Yui, you mean......" Conan looked up, he understood what Yui meant.

Wei slowly ran out under the piano and said lightly: "Speaking of which, of course Keiji Aso's death is very interesting, you say, is that just killing people together!"

Conan frowned and said, "Yui, you mean ......"

Wei helped Lan up, chuckled, and said in a low voice: "Conan, you know, I'm not good at reasoning, but I can see the discord, for example, you just lay on those blood stains, and your clothes are not stained with blood on them, you also know that it takes fifteen to thirty minutes for blood to coagulate, and it was only a few minutes when we rushed over?"

"Isn't the murderer, then...... Wait, I see!" Conan himself is very good at reasoning, he didn't figure it out at the moment, it was just not expected, now, only give him a little bit to break these flaws, he will figure it out immediately!

"Figured it out, who is the murderer?" asked Yui curiously.

As a person who is not good at reasoning, don't look at the "killing feast" she provoked, but she really didn't figure out who the murderer in this case was, or rather, she didn't figure out who killed whom.

Lan was also curious and asked, "Conan, do you already know who the murderer is?"

"Ah, got it!" Conan nodded and said, "But, it's not the guys, it's the guys." ”

"Huh?" the Maori sisters were stunned.

"Guy...... "The only one stunned.

Lan also said in surprise: "Conan, what do you mean by this? Isn't this murder committed by one person?"

Conan said, "Ah, yes, if I hadn't made a mistake in reasoning, these three murders weren't committed by one person. ”

Wei nodded thoughtfully and said, "I see, no wonder I always feel that everyone's alibi is strange!"

"Yes!" Conan also said, "Since it was not a case committed by one person, it would be strange to have an alibi, but now the question is ......"

Wei looked at Conan, who was still frowning slightly, raised his eyebrows and asked, "What? Conan, do you still have anything to figure out?"

"Evidence. Conan pursed his lips and said, "I have no proof." ”

The Maori sisters were also silent, indeed, if there was no evidence, even if Conan deduced the truth of the case, he would not be able to convict!

Lan understood next to him and asked, "Sister, didn't you and Conan think of the evidence?"

Wei raised his hand and brushed his hair, and said with a slight sigh: "It's not that we didn't think of it, the most important thing is that those people are already dead!"

"Are they all dead?" Lan was stunned, she understood this time, and said in surprise: "Sister, you mean?"

Yui shrugged his shoulders and said, "yes, huh, where is it?" and inadvertently, Yui saw something that existed in the open.

Conan noticed Yui's strange appearance, looked at Yui's line of sight, and understood what Yui meant, laughed, and said, "Yui, if you didn't guess wrong, we should have evidence!"

Yui laughed, blinked and said, "If you go to dig out that dark grid, you shouldn't be able to wear gloves on your hands, right? Besides, those powders just now seem to be worth a lot of money!

Conan nodded and said, "That's how it should be, Lan, Yui, we should go to the town hall too! Officer Twilight has already brought all the suspects over, so we just need to take a look!"

"That's right!" Yui nodded.

Although Lan didn't understand, she knew that her sister and childhood sweetheart had seen through the truth of the whole case.

By the time the Maori sisters and Conan arrived at the town hall, Officer Twilight had already brought all the suspects over.

"The three cases that occurred on the island have been confirmed to be the hands of the same person, Miss Reiko Kuroiwa has an alibi, so she is directly eliminated from the suspects, and the rest is Mr. Hirata, the secretary of the village head, who has no alibi, Mr. Shimizu, a candidate for village head, and Mr. Murasawa Monday, who is still unconscious, and one of these three people must be the murderer. Officer Twilight said, turning his head to look at Narumi Asai and asking, "Hasn't Mr. Murasawa woken up yet?"

"Yes. Asai nodded.
