Case

Situation

Part 1

Kogoro recieved a strange letter from a man named Keiji Asoh, asking him to investigate something on Tsukikage Island in the Izu coast, under Tokyo's jurisdiction. Kogoro, Conan, and Ran go to the island to only discover that Keiji Asoh had died twelve years ago.

Although he died from heart attack, the similarity to the death of Keiji Asoh caused the islanders to think the piano has been cursed.

While the group are waiting outside, suddenly the first movement of Moonlight Sonata is played, and Hideo Kawashima was found dead in the piano room.

Resolution

  Show spoilers »

The person who knocked out Murasawa in the piano room was Kazuaki Hirata. The bandage on his left hand was the result of smashing the window when he was trying to escape.The piano room was his meeting place with Kawashima when doing business: dealing drugs. He was using the piano's secret compartment as a hiding place for the drugs to which he exchanged later for large sums of money. The reason why he was always talking about the cursed piano was because he wanted to keep everyone in the town away from it. Murasawa saw the drugs that he had left in there earlier so he hit him. Still, he was unrelated to the murders because he wouldn't have related the piano to the crimes.

In the second murder, they found that he had been dead for only a few minutes but when Conan fell on the code of blood, it didn't smear when it takes 15-30 minutes for human blood to dry. It was just a trick that the killer used to manipulate the time of death of the victim. Upon looking at the pictures, there was a button that was shining near Kuroiwa's neck. But after the body was moved, the light was turned off. This was actually the reverse button. While the police weren't looking, the killer turned off the light. The killer used the reverse side (the blank side that didn't have the song), which played for over 30 min and then it reversed. That was when the 5 minutes and 30 seconds of gap played before the music started.

In the third murder, the killer didn't have the time to put a chair or desk at Nishimoto's feet because he had to escape in time.

The purpose of drowning Kawashima was to send the forensic examiner back to Tokyo, because it was impossible to do an autopsy on the island. The tape in the second murder was a setup so the killer could create an alibi.

Conan deduced that the killer was Narumi Asai and that she was, in fact, Asoh's aforementioned son, Seiji Asoh. Asai was probably the surname of the family that adopted him. After graduation, he came to the island as a female doctor. The pronunciation of his name was not written on his diploma, nor the medical license, because if they checked his history, they would have found out that he was a man: the kanji forming Asoh's name could be read as either "Seiji" (a male-only name) or "Narumi" (a female-only name): coupled with Asoh's feminine features and rather girlish voice, it let him masquerade as a female doctor rather well, plus falsifying the times of death and manipulating the crime scenes.

Suddenly, Seiji dissapeared. It turns out that Seiji, who had realized that he had been found out, locked himself inside the community center piano room and set it on fire, intending to die like his father.

Conan, carrying Asoh's last music sheets with his message for the then-young Seiji, managed to slip in and told Seiji, who was sitting at the piano, to keep on living.

Seiji's motive dated back when his father, the pianist Keiji Asoh, and his family was murdered. Kawashima, Nishimoto, Kuroiwa, and Kameyama used Asoh's international concerts as a front for their international drug trade. When Asoh stated that he wouldn't cooperate any longer, they got scared that their secret might be exposed, so they locked the family in their home and set it on fire. This was all written in the sheet music that he left behind in the safe as his confession to his remaining son. Seiji was hospitalized in Tokyo at the time of the murder.

Seiji went back to the island, under his "Narumi" disguise, because he never believed the official "Keiji Asoh killed his family and himself" version and wanted to find out the truth. When he told Kameyama that he was Asoh's son, the late mayor was terrified and told him everything and then had a fatal heart attack. Seiji played the Moonlight Sonata that his father loved so much upon seeing the mayor dead, and ultimately that gave him the idea of taking justice in his own hands.

When Seiji was done, Conan insisted that he should escape and live; Seiji refused, however, saying that he was now also like his father's murderers, covered in blood. Then, he grabbed Conan and threw him through the window, saving his life. Afterwards, he played one last music code message in the burning flames: "Thank you, little detective".

Suicide
	Location: Community center piano room in Tsukikage island Victim: Seiji Asoh Cause of death: Burning Seiji commites suicide after he was discovered to reunite with his father, sadly, Conan didn't manage to save him.

As for Murasawa, he was an admirer of the late Asoh and he was the one who kept the donated piano in tune just like that night.

After the case, while on the boat returning to Tokyo, Conan and Ran talked about Seiji. Ran wonders why did he sent Kogoro the letter when he knew how risky that would be for his plan, and Conan speculates that Seiji wanted Kogoro to stop him.
