Sunday, March 31, the thirteenth day of the lunar calendar.

After Yamazaki had breakfast today, he slowly walked to the Maori detective agency next door. In the office, Lan is taking Conan for a month-end cleaning, and Maori is lying behind his desk watching TV, but he doesn't seem to be in good spirits. Yamazaki understood that Mori was still worried about it, and that day was coming soon. But it's none of Yamazaki's business, so Yamazaki asked Lan for a glass of water, and read the morning newspaper on the sofa.

After the Akagi Quantum incident, the detective agency has not received any decent commissions, and this week it has received not even one except for a letter of entrustment, and this letter of commission has become a source of Maori's troubles. This letter of entrustment arrived four days ago, and it is a strange letter of entrustment, because it is not written directly by hand, but composed of words of different sizes and colors, and pasted them one by one. The content of the letter is like this, on the night of the next full moon, on the island of Moonshadow, there will be shadows that will begin to disappear again, please investigate, Keiji Aso.

Maori's annoyance was that the letter meant that something bad was about to happen on Lunaris Island, and his righteous heart wanted him to stop it. However, the small island of Lunaris ...... And he didn't say anything...... If he was busy in vain, wouldn't he have to do it backwards? His professionalism prevented him from doing such a thing. So, Maori's mood is a little tangled these days.

Shortly after Yamazaki sat down, the phone on his desk rang. Picking up the phone casually, Maori said weakly: "Hey, Maori Detective Agency." ”

"There are still two days left until the full moon. A man said.

"Full moon?" Māori immediately asked, perked up, "Who are you?"

"Keiji Aso on Moonshadow Island. The man introduced himself and tried to hang up the phone as he spoke.

"Wait a minute, you listen to me. Maori immediately shouted, "Hey......"

"By the way," Keiji Aso said again, "I've prepared the commission fee of 500,000 yuan, you must come and get it." After saying that, he immediately hung up the phone.

Throwing the microphone on the phone, Maori complained, "Really, a guy who talks to himself." Then he smiled again, "However, for the sake of 500,000 yuan, I forgive you." Then he laughed and said, "Okay, I've decided, I'll go to Moonshadow Island early the day after tomorrow." ”

"I'll go too, I've long wanted to relax on a small island in the Izu Islands. Lan smiled, "It's a holiday, so we just go together." Then he asked, "Isn't it, Conan?" and thought to himself, it's too dangerous for you to go alone, and I'll have to go with me.

"Hmm. Conan immediately agreed.

Yamazaki smiled: "It doesn't matter if he says it, this has to be agreed by his boss Mei Daiko." ”

"Alright," Lan said, "I'll talk to Mei Daizi in the evening, and I'll make up for it later." Then he asked, "Isn't it, Conan?"

"Uh-huh. Conan replied with a wry smile. ……

In the evening, Mei Dai Restaurant.

At seven o'clock, after sitting down, Lan told Mei Daizi about it through Qingzi, and before Mei Daizi could speak, Kaito, who was sitting next to Conan, protested: "No, I protest, you are going, then I will go too." ”

"Protests are ineffective. Mei Daizi said angrily, "I didn't leave you alone." That place on Lunaris isn't interesting, I'm not going to go. Then he said to Lan, "Go ahead." Then he asked aloud, "Brother, how many days will you go?"

After thinking about it, Yamazaki, who was sitting next to Kaito, said, "I don't know, at least one night, maybe two nights." ”

"Add that the night a few days ago, and that's three nights, and in that case, that's six days more. Mei Daiko said, "Conan, you have to remember it yourself, don't forget. ”

"Okay. Conan, who was sitting next to Lan, smiled bitterly, "I will." ”

"Well," Midaiko said to Kaito, "I'm okay now." ”

"Nope. Kaito laughed, "Not at all." ”……

At this time, at the counter in front, Mori was talking to Mimiko Miyamoto.

Touching his face with his fingers, Mori said embarrassedly, "That, Miko, can you lend me a yacht." ”

"No problem. Miyamoto Miko replied immediately.

Maori immediately laughed, "Great." ”

"The cost of fuel is 30 percent," Miyamoto said with a smile, "The helicopter is borrowed for free." ”

"No, no," Maori said quickly, "the small one, I can do it if I want the small one, and the fuel cost is half as usual." ”

"This is already the smallest. Miyamoto Miko smiled a little helplessly, "The others smaller than it have been harmed by Meidaiko in the past few years." ”

"Then I didn't say it. Maori said and wanted to leave.

"How about the fishing boat?" Miyamoto Miko smiled, "I don't need money, the second is Tuesday, you can take the fishing boat over." ”

"That's great. Maori immediately laughed, "Thank you so much." ”……

Tuesday, April 2, the fifteenth day of the lunar calendar.

Early in the morning, an ocean-going fishing boat approached Moon Shadow Island in the fog, and this was the boat of the Maori Four. Just now, a crew member informed them that Moonshadow Island was almost here, and they came out of the cabin to see what Moonshadow Island was like.

"Ahh ”

Conan whispered, "You didn't want to come by yourself. ”

"If he doesn't come, how can you come. Yamazaki smiled, "When you saw that letter, you must have wanted to come." ”

"What are you talking about?" Lan asked.

"We're talking about when the fog will lift," Yamazaki laughs, "so you can't see anything clearly." ”

"It should be soon," Lan said, and then said in surprise, "Look, it's already starting to disperse." Then he looked at the island that was slowly approaching, and couldn't help but exclaim, "It's so beautiful." ”

"What's pretty," Maori said angrily, "this kind of island ......"

"Look at so much greenery on it, it must be an undeveloped island. Yamazaki said, "If you don't even have electricity......

"Ah!" Lan said in surprise, "no. ”

"Don't worry, Sister Lan," Conan laughed, "Didn't that Keiji Aso call?" Even if you have a phone, there will definitely be electricity. ”

"Alright, I've seen the island," said Maori, "go back, rest and get ready to go to the island." ”……

The four of them were dropped off by the ocean-going fishing boat and left, and the four of them inquired all the way, and soon arrived at the village office.

At this time, there were many villagers in the village office, sitting together and talking. Looking at the young staff member sitting behind the sign at the reception, Mori asked, "Hello, may I ask where Mr. Keiji Aso lives? ”

"Ah, please wait a minute, let me check it out. The staff looked it up on the resident register as he spoke, and then said, "It's weird, I can't find the name Keiji Aso." ”

"Please look for it again, okay? "By the way, here's a letter he sent me." As he spoke, he took out the letter of entrustment.

The staff member was embarrassed and said, "However, there is no record of his registration on the resident register." I'm new to the island and don't know much about it. ”

At this time, a middle-aged man came over and asked, "What happened?"

"Ah, Director, this gentleman is said to have come here on the behalft of the island," said the staff, "a gentleman named Keiji Aso." ”

"What?" the director exclaimed in surprise, "Did you say Keiji Aso?"

"Ah......" The villagers sitting around, including the staff in the government office, were immediately shocked, and then began to whisper, looking very strange.

Yamazaki asked, "Is there anything wrong with that?"

"There's no such thing, because, because ......," said the director, fearfully, "he—he died more than a decade ago." ”

This surprised the four of Maori together, and then Yamazaki asked curiously, "How did he die?"

"Please follow me. With that, the director led them to a side hall.

After sitting down, Yamazaki asked, "Now can I talk about it?" ”

"He was born on this island and is a well-known pianist. "It happened twelve years ago, on a full moon night. After many years, he returned to his hometown and held a piano recital in the village hall. However, after the recital, he suddenly closed himself and his family in his home and set it on fire. It is said that he killed his wife and daughter with a knife, and continued to play the piano in the raging flames as if they were entangled in something. That's right, it's Beethoven's piano sonata, "Moonlight". ”

"Oh?" Yamazaki laughed, "Suicide." ”

Holding Maori's arm, Lan said fearfully, "I'm so scared of people." ”

"In that case," said Maori, "then we will take our leave." With that, he stood up and left with the three of Yamazaki. ……
