"The letter is very simple." Conan spoke his opinion.
"Hakuba Saguru's letter is describing about the culprit. The only clues about the murderer is the white mask skull. But the problem is this white mask skull. This is not enough to know who is the culprit"
"Hey, kid. What do you want to say?" Mouri interfered.
"What I want to say is how about we ask people on this island. Maybe someone know about this mask."
"Good idea. Let me go out and ask." Mouri took a copy of picture then left.
Conan felt doubt about this clue but he couldn't point out what was wrong with it.
"Then Hattori's letter is telling the time that he commits murder. 3 days for each victim. That means we have to wait for 3 days more so that we can catch him."
"Uhm. But I'm not sure we can catch it by ourselves" Hattori shook his head.
"I mean just look at this scene. This prove the murderer this time isn't normal."
Hideo's body scattered everywhere in the room making everyone have to think again.
Even he couldn't solve how he could kill victim in short time.
He was invited here because of challenge letter. Now, he was obsessed by murderer at this time.
'3 days for each victim.' Conan thought.
"So, Hattori-nii-san. Did you find the relationship in this case?"
"Ah. Not yet."
"Asou Keiji. This person is the only clue solving this case."
"Aren't that person dead?"
"He did but what if." Conan stopped in middle. "He has family."
Hearing this, Hattori found out something then left the room.
'Just as I thought. The one who invited us and them here must have some clues but I don't know who write those letter yet.'
Conan took out his note and wrote down every small details.
3 days later.
"For the safety of everyone. I require you guys staying near the police. We will protect you from murderer." Megure said.
Everyone expressed their stress and fear through their eyes and action.
"What's a nonsense. I want that piano disappeared as soon as possible. Do you clear?" Tatsuji Kuroiwa angrily said and left the room. He didn't care about his own safety anymore.
Police could only look at him leaving.
"So what's about you guys." Megure said.
In the end, they all accepted excepting Tatsuji Kuroiwa who had just left.
2 minutes later.
"Tsk. Just a music sheet" Tatsuji arrived a broadcasting room and found a music sheet on the floor.
Remembering his past deed, he just wanted to take that music sheet and burned to ash.
"Dead people shouldn't meddle living people."
When he bowed down to pick it up, his shadow suddenly became larger.
"Hmm" He slowly turned his head back and found a man clad in black cloak and wore white skull mask standing behind him.
"In the horror movie. It's a common sense that you shouldn't separate each other." I said.
"Who are you. Are you here to kill me? I can pay you double. Please. Let me live." he roared out loud.
"Me. I'm your worst nightmare. One that you wish you never went out alone." I slowly approached him.
"Wait. 250%." he slowly walked backwards.
I didn't reply but continued approaching menacingly.
"300%" His fear was increased.
"400%. Please state your price. I can pay it."
"My price." I raised the demon arm. "Your heart."
The red arm stretched out and touched his heart location on the surface.
He fell to the ground and found that he was still alive. He quickly stood back up and moved to the corner.
An image of mirror heart was on my red arm.
Feeling nowhere to run, he turned on the mic with an intention calling the police.
"Go die." I crushed it. His heart on his body was also crushed like the one on my hand.
Feeling intense pain around his heart location, he let out his scream for a short moment before dying.
"Ahhhhhhhhhhh"
A scream rang out reverberating through the building.
"Broadcasting room" Conan said then dashed at full-speed.
I looked at the corpse on the ground without any emotion. I clicked the button to play Moonlight Sonata music.
After feeling someone near, I left the scene.
Conan opened the door and found Tatsuji on the ground. He moved near to him and inspected his body.
"Uncle. Uncle." Conan checked his mouth and found no sign of being killed by poison.
No sign of physical contact was on his body.
"How can he die?"
"Another victim. That's strange. I stood at the stairs and only saw Tatsuji. No one excepting him uses the stairs." Hakuba said.
Another person hurriedly entered with body covered in sweat.
"I stood outside and found no one escape the building. That means the culprit is still in the building." Hattori said while exhaling heavily.
"That can't be true. I was there with everyone. No one left the room." Conan added.
Thank to this, they drew conclusion that the murderer wasn't one of people in the building.
Both of them also checked corpse.
"That's strange." Hattori said in great surprise.
His blood was running down staining the floor. No physical impact was found. No poison also wasn't found.
How can he die.
"No external contact." Hakuba inspected more closer.
"What's wrong. Is Tatsuji fine?" Megure asked and found the corpse on the floor.
"Never mind. Forget what I asked."
Conan turned back and saw another person.
"Narumi nee-San. Can you perform autopsy now?" Conan asked.
"Ah. No." Narumi kindly replied.
"Please. Nee-san."
"Enough. We will record everything. Let the police work from now." Megure picked Conan up and reprimanded.
"I think you should perform autopsy now." Hattori said.
"Hah."
"Same opinion. Officer Megure. Please do autopsy as soon as possible. Or else we will lose important details." Hakuba also added.
"This." Megure looked at Narumi.
"It's fine. I will go and fetch my tools."
10 minutes later.
"Here we go. Beside. Aren't you too young to watch this?" Narumi said to Conan.
"It's fine. My mother is a doctor. I saw this many times before." Conan laughed it off wanting them not to kick him out.
"Okay. Let me first open his chest." She opened chest location.
"The ribs are fine. Hah." Narumi exclaimed in surprise.
"What's wrong? Nee-san."
"A heart." she stuttered. "was crushed"
Conan, Hattori and Hakuba brought their head closer to inspect. Indeed, the victim's heart was crushed.
"How" Conan was confused.
There were no external contact. So how can his heart got crushed.
"This methods of killing. I didn't hear it before." Hakuba pulled his hat down and left.
Too much strange thing that he couldn't explain.
Hattori and Conan tried their best to find every single clues. Even a dust on the ground was also recorded in details.
"Tsk. Damn it." Conan slammed the ground.
"Another victim."
In the end, 3 teenage detectives couldn't find any clues.
They reached the dead end like before.
