"No, the postmark on this letter was stamped ten days after the murder, and it shouldn't have been sent by him."

Hattori Heiji frowned slightly, "Although the sender's name was written by Kohei Wakamatsu, the content of the letter seemed to be written by the murderer who killed Mr. Wakamatsu."

Conan looked up, "Murderer?"

"Yes, this is what the beginning of the letter is written." Hattori Heiji said: "Dear Mr. Heiji Hattori, because I really want to meet you, a high school detective, so I want to confess to you the crime you have committed. However, even if I meet, I have a little doubt if you can see me clearly?

This is because I was made up by you humans without authorization. An abnormal existence is an illusion that you will never be able to truly see. If you still want to meet me, on the next full moon night, I will wait for your grandfather at the home of the man I killed.”

Hearing this, Kogoro Mouri had a speechless expression, and this kind of speech was too subtle.

Hattori Heiji looked at everyone, "Then, at the end of the letter, the address of the victim Mr. Wakamatsu's hometown in Osaka, besides these..."

He fell down the envelope and took out a key from it.

"There is also a key to that house in the envelope."

"Have you been there?" Chen Xing asked.

"I originally planned to go there to expose his identity, but I didn't expect to catch a cold accidentally." Hattori Heiji looked at Heye helplessly, "So she took the key away because of her arguing."

He snorted with Ye, "I'm going on your behalf, okay?"

"Have you gone alone with Ye?" Maori Ran said in surprise.

"No, I brought three friends to the house at that time. They said this was very similar to an adventure game and agreed very simply." He Ye said: "Therefore, it didn't look like a ghost haunted house at all. I think it should be the place where the deceased president would live when he returned to Osaka occasionally. Not only was the house cleaned very clean, but some electrical appliances could also be used."

"Well, is anyone waiting for you in that house?" Shiliang Matsuru asked.

"Even if the doorbell is ringing, no one responded. We couldn't help but open the door with the key without authorization. Unexpectedly, the room was still very beautiful." He Ye said with a smile: "I originally wanted to test my courage, but it turned out to be a trip to visit the luxury house."

As she said that, she frowned, "Then we want to see the bathroom in the mansion, and we all went to see it together."

"Look at it?" Ran Maori became nervous.

"There is a terrifying person with long hair leaning against the wall of the bathroom, sitting there!" He Ye's face looked scared.

Conan hurriedly said, "Did you talk to that person?"

"After we found that person, the lights were all gone. When I discussed with my friends whether to call the police, I heard a terrifying sound. " He Ye said: "Because we were too scared, we were planning to leave, but the electricity suddenly recovered, and the person who was still sitting there just now disappeared."

After the words came, Ran Maori was still a little scared in the scene, so he heard Kogoro Mori hum disdainfully.

"It must have been that I ran away quickly after using the remote control to power off."

He is an old detective and can see through such inappropriate tricks at a glance.

Hattori Heiji curled his lips, "If it were only that guy who disappeared, I wouldn't have to run far to Tokyo."

He said: "Because there was a piece of paper left in the bathroom where the guy disappeared."

"Paper?"

"There is a paragraph of text written by a typewriter on it." Hattori Heiji said: "What disappears is only his body, not his words."

"Writing?" Shiliang Zhenchun said inexplicably: "What does that mean?"

"The guy leaned against the wall, near the tiles on his head, seemed to have words engraved with something like a knife," Hattori Heiji said.

He Ye nodded, "There are three large English letters engraved, e, y, e."

Eyes? Conan thought.

"That text also disappeared while the man disappeared." He Ye said: "But the paper reads 'The text did not disappear'."

Kogoro Mouri guessed: "Will that be, exchange it with tiles that are not engraved elsewhere?"

"There are indeed many scratches left on the tiles under the wall. I thought so at the beginning." He Ye frowned and said, "But the colors of those tiles gradually become lighter from the top of the wall to the bottom. If the tiles below are really exchanged with the top, the colors will be found immediately."

Conan asked, "Hatsuke, have you seen those tiles too?"

"Yes, but because of the need to be rebuilt, the people who were working there were very tightly since that day and didn't let me go in and see it." Hattori Heiji looked speechless.

Conan asked Ye: "Then do you remember how long it took for the power outage?"

I thought with Ye for a while, "It should be less than 5 minutes."

"It seems that I should have prepared in advance." Kogoro Mori held his chin and said calmly: "Be prepared for the same color tiles with the words carved, and then exchanged them in the dark, and the tiles with the words were taken away by that guy."

But he immediately frowned, "Although this reasoning is reasonable, why is such a boring method designed for?"

"Only people think so, but what's next is the key." Hattori Heiji said, "When Mr. Wakamatsu was assassinated in Karuizawa, he was also in the bathroom with the same tiles.

However, when his body was first discovered, there should be a message before death left by Mr. Ruomatsu with his blood, but after the police arrived, the messages disappeared inexplicably."

"His message before his death disappeared?" Maori Ran was a little puzzled.

"Because Mr. Wakamatsu's fingers were covered with blood, it was obvious that he must have written some words." Hattori Heiji said.

Kogoro Mouri pondered: "It should be that the murderer who sneaked back to the scene secretly discovered it and deliberately wiped it off."

Hattori Heiji shook his head, "In that case, there should be blood reaction on the tiles near Mr. Wakamatsu's fingers."

Ran Maori guessed: "Can you exchange it with bloodless tiles like the one He Ye saw?"

Hattori Heiji said: "It happened that time that Mr. Wakamatsu was replacing the tiles in the bathroom himself, and the adhesive on it seemed that it had not dried. Of course, it might have been exchanged.

But there is also the same as what Ye saw. The tiles are getting lighter and lighter from top to bottom. If they are exchanged, they will be leaked immediately."

After hearing this, Conan couldn't help but fall into deep thought.

Hattori Heiji leaned over and chuckled, "Maybe it was the same method that the person Kazuya saw, who used the same method to make the text disappear. Do you think so?"
