The Phantom Thief of Heart! But Conan.

"The same way of death as Mr. Kawashima..." Without being allowed to follow Asai Narumi, Mao Lilan leaned on the bed restlessly, "Is it some kind of special poison?"

The Tokyo police have arrived and have taken away the village chief Kuroiwa who was probably involved in drugs. However, under heavy siege by the police, Kuroiwa Tatsuji still died.

"It's hard to say. It may be a special drug with a delayed effect, or it may be a long-term chronic poison..." Conan answered Mao Lilan's question casually, but he was thinking in another direction.

Three deaths, three deaths, excluding Ken Nishimoto, who may not have been a homicide. The circumstances at the scene of the two deaths were complicated, and the cause of death is still unclear... To deduce the possible murderer based on techniques, there are so many unknown conditions. , the difficulty is still too high.

For now, we should still consider it from the perspective of motivation.

Considering only the underlying logic of the incident, they already have a lot of information about this strange island.

First of all, there is a high probability that the murderer is the client who sent the commission and mailed the letter to Uncle Maori.

This person invited Kogoro Mori to the island in the name of Keiji Aso. It’s hard to say whether his purpose was to challenge the detectives, or whether he wanted the truth about Keiji Aso’s death to be revealed to the world. This person must be related to Keiji Aso. characters.

In the letter, the client accurately stated that there would be shadows disappearing in the moonlight, which is completely consistent with the three deceased people who died one after another in "Moonlight Sonata". It is too unlikely to say that the sender is not an insider.

The reason why the word "again" is used in the letter, combined with "full moon night", is that the three deceased people this time must be related to Guishan who also died on the full moon night two years ago.

The piano that Kameyama Village Chief played when he died was discovered two years later. Heroin was found at the bottom. Hirata Kazuaki, the village chief’s secretary who has been repeatedly emphasizing the "curse of the piano" and "cannot touch the piano" , it is the drug-related personnel related to this thing...

What are the connections between these people, and how are they related to Keiji Aso?

While thinking, Conan noticed from the corner of his eye the old policeman who walked into the infirmary, opened an oxygen bottle, breathed oxygen, and eased his breathing.

Because he ran all the way along the highest residential area on the island to the clinic at the foot of the mountain, the old man with a gray beard and gray hair was obviously having trouble breathing. So before Asai Narumi left, he kindly let him rest in the infirmary to show that he You can ask for a police escort to send them here.

Conan, whose desire for reasoning was at an all-time high, moved closer to him and asked in a low voice: "Grandpa, you said before that you stayed on the island for decades... When Mr. Aso died more than ten years ago, Are you on the island?"

"You said he set fire to his own house? Yes." His voice was slightly muffled through the oxygen mask.

"Oh, then, did Mr. Aso really burn down his own home? We came to the island to investigate after receiving a commission related to him. Is it the same as what Mr. Ken Nishimoto said? Did Mr. Keiji Aso or his family really die in that fire?" Acting like a curious child, Conan pestered him and asked.

Mao Lilan, who originally wanted to stop Conan and tell him not to disturb the old man's rest, couldn't help but feel curious when he heard this question. He took two steps closer and waited for the old man's answer.

"Well, at least, that's what the eyewitnesses said at the time." The old policeman pushed up the retro-style glasses on the bridge of his nose with a look of reminiscence, "That was such a big fire, it turned the sky red. ...After the fire, we specially invited the police from Tokyo to investigate, and the DNA of their family was indeed detected from the skeletons at the scene. All three members of Aso's family died in the fire, which is absolutely certain."

"Witnesses?" Conan blinked and caught the key words, "Who are they?"

"Well, let me think about it..." Adjusting the position of the oxygen mask, the old man squinted his eyes and thought for a while, then replied slowly, "The former village chiefs Kameyama, Kawashima, Kuroiwa Village Chief, and Nishimoto, Just the four of them."

Conan's eyes widened.

Mao Lilan, who was listening to them on the side, also raised his hand to cover his mouth: "Doesn't that mean...all the witnesses of the fire are dead?"

"Yes, it seems like that." Touching his chin, the old policeman nodded suddenly, "The four of them, including Aso, had a pretty good relationship when they were young. Our island is not big, and their families are relatively well-off. Well, we have been playing together since childhood. The five of them went to learn piano together. Later, Aso insisted on learning and became a well-known pianist. Nishimoto was the one who fell off the cliff before. He often went overseas to participate in his performances. I’m cheering him on.”

"Childhood friend..." Conan whispered, his mind spinning again.

All five of them have piano skills, so when Kameyama died, no one on the island seemed to have any doubts about his playing "Moonlight".

Therefore, Ken Nishimoto was so frightened when he saw the sheet music that he rushed out of the door and ran out in panic...

Quickly turning out the small book where he had copied the live music score, Conan stared at the strange fourth line of music and began to think.

What code words will there be...

----

"Yes, it is similar to the state of death of Mr. Kawashima." Standing up straight, taking off the medical gloves on his hands, Asai Narumi lowered his gaze and stared at Kuroiwa Tatsuji, whose expression was inexplicable and full of pain, and said calmly Narrated, "I cannot give an explanation of the cause of death. As for the time of death... you are all present, so there is no need for me to explain."

"What a headache." Megure Thirteen raised his hat to dissipate the irritating heat on his head. "It seems that we can only wait until daybreak to send them to an institution in Tokyo for specialized testing."

"After what happened in Kawashima, Kuroiwa Tatsuji returned to his residence accompanied by his family. According to his daughter's testimony, he had no contact with anyone other than his family before our arrival." One night was not obtained. How much sleep he had, and because of all kinds of incidents, Kogoro Mouri's face was clouded. "That means he hasn't been in contact with other people for seven or eight hours. Is there any lethal poison with such a delayed effect?"

It's not like he has never encountered cases where capsules or other wrappings were used to delay the action of poisons.

But no matter which method is considered, this length of time is somewhat amazing.

If we were to go back seven or eight hours, everyone among the thirty or so residents who participated in the ritual would be suspect.

"I'm not sure..." Asai Narumi blinked, firmly remembering the terrifying posture of his enemy before his death, and at the same time slowly added, "But if the symptoms are 'organ failure', 'corners of mouth and eyes' Characteristics such as "weirdly colored bodily fluids oozing out", I have seen similar situations on the island before."

"Have you ever seen a similar situation?!" Megure Thirteen and Mouri Kogoro repeated in unison, their attention suddenly heightened.

"Yes, two years ago, although the death of Kameyama Village Chief was finally confirmed to be a heart attack at the Tokyo Forensic Laboratory, his state at the time was similar to this." Asai Narumi nodded, thinking After encountering the Phantom Thieves today, I had some understanding, but also raised the corner of my mouth in sadness.
