"The lips, fingers, toes and fingers of the corpse have turned purple, and there are bleeding spots on the conjunctiva of the eye, indicating that the deceased died of suffocation! There are no obvious marks or drowning on the body of the deceased, and there is no painful expression on the face, so I boldly guess that the deceased was suffocated by numbing his nerves with poison! That is, using a highly poison that can kill people in an instant!"

"In terms of death time... according to the temperature of the corpse, the condition of the corpse spots and the corpse after death but there is no corpse zombie yet, it should be less than 30 minutes since his death! In other words, the deceased was killed within 30 minutes before we entered the study! The murderer should be the person nearby! In addition, the doors and windows just checked are intact and there are no traces of violent destruction! Humph! It is necessary to set up a secret room environment in such an ingenious way, and the murderer must be an acquaintance who does not want to be found, that is, you who are still in the room when we arrived around four o'clock!"

As Hattori Heiji took the lead in firing, after a fierce reasoning and judgment, the Ikemura family, who followed the police to the study, all showed shocked expressions.

"Hehe! Meguro Police Department, right? I asked for the admission of these people to prove that they are absent!"

"This...reasonable! Takagi! Go and take this group of people to admit absentee certificate and ask what they are doing between 3:30 and 4:00!"

"Yes! Memu Police Department!"

So Hattori, who chose the breakthrough, showed a proud smile to Kogoro Mori and followed Takagi to the next house to listen to the absentee certificate.

Although his body became smaller, Conan, who still recognized himself as Shinichi Kudo, did not want to lose in the face of this high school detective from Osaka. So after thinking about the other party's judgment, he nodded in agreement and followed Takagi to the next door to listen to the absentee certificate.

"Brother Maori! Why are you still here? Look at the boy named Hattori just now, with his proud look! This is simply despising all the righteous forces in Tokyo! It is a contempt for our methods of solving cases! Why don't you hurry to go to the room next to listen to the alibi of the suspects?"

As the saying goes, the emperor is not in a hurry, and it is fine if the eunuch is slapped in the face by the local detective. A little devil from Osaka also slapped him in the face and pressed him, the boss who was responsible for the search for murder cases, to force the third department to the ground and rub him. When Shinichi Kudo left without saying goodbye, only Kogoro, who was rising up in the army, had no choice but to hold on to the ground, the police department of Meguri could only hold his thigh tightly and try his best to provide the help he could provide.

"Proof of absenteeism? Isn't Conan over? Don't worry! And there are Takagi's records, I can read it later! I still care more about the scene than these! Meguro Police Department, do you think this stack of books is strange? I just came in and didn't care much! Do you feel awkward when you read it now? Just like the arrangement we used to be when we were distracted when we were sleeping in school and were afraid of being caught by the teacher! And..."

With the gloves that he had asked for from the forensic department, Kogoro Mouri carefully picked up the stack of books and read them one by one.

"These books were obviously moved from the bookshelf in panic! There is no connection between them at all! It has been denied that the deceased was looking up information or something! In this case, the question arises! What is the purpose of the person who stacks these books?"

"This... Brother Maori! What do you think is the purpose?"

Faced with Maori Kogoro's question, Memu Police Department followed the idea and threw the question back.

"Hmm? Well! If there is no mechanism or something like that, then its function may be the same as when we were in school, just to block the dead! But wasn't it just him and the dead in this room at that time? What was he afraid of when he blocked the dead? Is there a third person in the room at that time?"

Although under the continuous summary and training of the sculptors, Kogoro Mouri had some dogmatic countermeasures such as these secret rooms and puzzles, such as trying the Roman method to solve puzzles, which really doesn't work with scales.

However, he still lived up to expectations and turned the perfect start to a path that no one else had ever imagined.

"My brother Maori means that there was more than one person in the room at that time? And the murderer killed Hitomizuki Ikemura when another person was not paying attention and then set up this secret room? Is he going to set up a proof of absence? But wouldn't that person doubt him?"

"Uh! Let me think about it again! Huh? The CD rack here is full of classical music! The deceased likes classical music? But when we came in, we were playing opera! Why? Is this the murderer's favorite murder habit? He listened to opera while killing people? Or did he want to use the sound of opera to cover up the sound of his killer? The problem is that the sound insulation of this room is very good! We just stood at the door, and before Mrs. Ichimura opened the door, I didn't hear the noisy opera sound inside! Why should he do this? Unless he wanted to deceive another person in the room, but the problem came back! If there was another person in the room! How could he arrange the secret room on the scene? Do you have to solve this secret room technique to solve this doubt? But I am really not good at decrypting the secret room! Is that little devil Conan not back yet? Damn!"

Kogoro Mori, who felt like he was in a dead end, was a little upset and flipped back and forth in front of the bookshelf in the study, hoping to find some new clues. Of course, he did not let the deceased die in the drawer in front of the desk where he was sitting.

The detectives have started looking for the murderer. I wonder if they were just a program after a missed salary forensic tool. After the people confirmed with the Meguro Police Department that the deceased had not committed suicide but was killed, and the cause of death was poison. Because the deceased had only the needle hole behind the ear, and if the deceased wanted to commit suicide, he would not have committed suicide in such a strange posture. At the same time, based on the judgment of the pinhole, it was not the deceased who stabbed himself with a needle to enter, but the oblique downward hole that was stabbed from behind.

"Okay OK! I get it!"

After casually flipping through the reports of his subordinates, the police department of Megu walked out anxiously. He wanted to go to the room next to see what progress Hattori Heiji has made? He didn't want to be the laughing stock of the police department. People will definitely say it on their backs in the future.

"Look! This is Megu who was defeated by the son of the head of the Osaka Police Office!"

"Oh? His son!"

"Yes! Just a high school student in Osaka!"

"Osaka native? Or high school student? Puchi! This guy Megu is so inferior!"

"Yes! Yes! It's so bad!"

"Damn it! You must not let this happen! Brother Maori, please! I also want to provide you with the help you deserve! I can still find out the enemy's situation!"

Just as Meguri police department went to the next room to inquire about the news, Kogoro Mori who was randomly rumored here received unexpected information.
Chapter completed!
