"Hmm? This is? Wait..."

On the top of the bookshelf, Kogoro Mouri accidentally saw a photo frame that was being put down. After erecting the unexpected dust-free photo frame on it, a familiar figure appeared in front of Kogoro Mouri.

The reason why I say that I am familiar rather than knowing is that my face is somewhat similar, but my hair color is different.

Thinking of something, Kogoro Mori hurriedly returned to his desk, took out a large fork in the drawer that had been drawn by Koto Ikemura with a red pen, and wrote the photo of the surname Yama Castle. It compared it with the photo in the photo frame.

In the photo frame, there is a man smiling cheerfully on the right side. According to his appearance, he is the deceased Hon Ikemura. The woman standing next to the man with a shy smile is much more interesting.

"It's really similar! If it's not a miracle, then it might be the truth? Ikemura Koe, Kaneki Yuki, Yama Castle? I smell the story! And it's a strong sense of sadness!"

After carefully taking out the photos in the photo frame and saving them with the photos in his hand with evidence, Kogoro Mori called another capable general from Meguro's police department to his face.

"Chanye! Go and do something and help me investigate the identities of Kaneki Yukiko and Koe Ikemura. They are not from the present, but from the past! Do you understand?"

Seeing the two people who looked like a pair of sisters in the transparent plastic bag in Kogoro Mori's hand, Chiba seemed to understand something, hurriedly explained a few words and left Ikemura's house.

On the other hand, after asking everyone's absentee certificate, a neighbor could testify that Koike Fumio, who was chatting with his neighbor at that time, first obtained a safety ticket. Koeike, who went to the Maori Detective Office to find Koegoro, who also obtained a safety ticket. He also received a safety ticket. Before Koegoro and the others arrived, Ikemura Takashi and his girlfriend Kaneki Yukiko claimed that they only came a few minutes earlier than Koegoro and the others, but they had been to the deceased's study room and still received a suspicious ticket. Even though they claimed that the study door was always locked, Koe Ikemura did not receive them.

Although Himemura Riki sometimes forgets when he speaks, he still knows what time he comes. Two o'clock, one is a lot of time! After leaving at least one o'clock in the morning, he has been at this home.

So is the suspect between these three people?

After listening to Hattori Heiji's analysis, Meguro's police department also stared at the three people and tried hard to patrol. He hoped that something abnormal could be seen from these three people.

Unfortunately, it's useless.

And at this moment, the forensics personnel who took the key of the deceased as evidence finally provided new clues, just like playing scripts. When you don’t know the direction you are heading, there will always be clues sent over.

"Well? There is such a mechanism in this key ring?"

After watching the decorations with the key ring hanging in his hand being opened by himself, revealing the tape on the upper and lower sides of the decoration and the traces of the thin rope that would be ignored if they were not careful. Meguro's police department pondered for a long time and felt that this important news should be told to Kogoro Mouri.

On the other hand, Hattori Heiji and Conan who saw this key ring seemed to have thought of something and wanted to confirm their conjecture. Unfortunately, Hattori Heiji went to see the door of the study, but Conan, who was following him, suddenly felt a sharp contraction, leaving him in place.

"Damn it! What's wrong? The chest... the chest hurts so much! The heart is as if it's being held by a big hand and kneaded it hard! Ah! It hurts! No way! In this case, I must defeat this kid from Guanxi as soon as possible and drive him away! Stop he guessing something and revealing my old secrets!"

"I……"

thump!

"Conan! Conan! What's wrong with you? Meguro Police Department, call the doctor!"

"Oh oh oh!"

Although I don’t know why Conan suddenly became like this just because of a cold, Xiaolan, who cares very much about him, found a quiet room according to his childhood illness, put Conan on the tatami, covered him with a bedding, and a wet towel collapsed on his head.

"Conan! You have to hold on!"

I don't know that my mouth was thrown into the competitor hidden in the dark and Hattori Heiji, who was looking for clues, finally found the fishing thread he wanted to find in the trash can.

"That's it! Humph! The murderer's secret room trick has been discovered by me! Kudo, haven't you appeared yet? If you continue to hide, I'm sorry! I will take this victory!"

After taking the evidence of his determination and correcting his baseball cap, Hattori Heiji proudly came out of Kawaji and returned to the study where everyone was already there.

"I have seen through who the tricks and murderer in the secret room are! Hehe! Mr. Kogoro Mouri, the famous detective in Kanto, where are you?"

"I'm not sure yet! Waiting for some information!"

"Are you waiting for some information? Hehe! Then I'll show off my ugly head first! This is the fishing line I found in the trash can in the wet room! Why did this fishing line attract my attention? Because it is very special! It has a needle on it! And this is the key to the secret room!"

So in the unwilling eyes of the Meguro Police Department, as if he was going to humiliate the group of police officers from the Tokyo Metropolitan Police Department, Hattori Heiji asked Meguro Police Department to be a model for the deceased. He used a needle to carry a fishing line through his pocket, then pulled it to the door and pulled the fishing line out of the crack under the study door, and then put the key of the evidence on it.

After doing everything, like the magician who was preparing to perform magic, Hattori Heiji, who set off the atmosphere, pulled the key along the crack of everyone's eyes and pulled it into the study room, then fell along the desk and the stack of books onto the legs of Megumi's police officer, and finally slowly slipped into his pocket.

"This? How is this possible?"

Seeing all this, Meguro police department stood up from the chair in shock.

"Nothing is impossible! This is the process of the murderer creating a secret room!"

"Mu Police Department! We just found this in the study. The preliminary judgment should be the weapon that caused the death of the deceased!"

Just as Hattori Heiji was about to end his performance, under the interference of the bastards who came in and out and came in again in the study, they finally found what they most wanted under the carpet under the desk in the room.

"This needle?"

Looking at the poisonous needles placed in the evidence bag, Meguru's police department asked again with a complicated expression.

"That's right! It's this needle! This matches the clue that the small hole behind the ear of the deceased who I just judged is the cause of death! The murderer stabbed the victim in the neck with this poison needle. After the victim died, he took out the key in the victim's pocket, and then..."
