Detective Conan: Twelve Death Warlocks

Guo Yixin's archery skills can be said to be superb, so Yutaka Ozaki hoped that Guo Yixin could represent Toto University in the national college student archery competition. After the training, the two chatted and went to the changing room over there, and happened to encounter this case.

Conan looked at Guo Yixin, very embarrassed: "Then what is the situation at the scene? At the very least, if it is a secret room, there should be some mechanism!"

Guo Yixin nodded: "Actually, Teacher Ozaki was going to open the room here, but the door was very tight, and I couldn't open it even with a lot of effort. So I went around to the back and looked through the small window at the back.

, and found that the mechanism inside was locked. Immediately, we worked together to open the door, and found the body of Mr. Shintani at the end. So I called the police."

"You called."

"That's right. After all, no one had cleaned the windows at the back and we couldn't see clearly, so we decided to open the door first and call the police immediately after seeing the body. However, the scene was not moved after hitting the door." Ozaki Yuya said.

Appearing helpless.

Shiratori Rensaburo nodded, proving the testimony of Guo Yixin. Conan fell into deep thought, with a slightly perverse expression. Everyone walked in to observe the scene, Shiratori Rensaburo pointed to the small window there: "This is where Yixin used to be.

The young lady used the small window for inspection. In fact, if you are not careful, and there is only such a shady window, it will be difficult to find the body without paying attention."

"Shiratori, do your police have any other suspects?"

Guo Yixin said: "In fact, if this is the case, I think there should be four people, or even me, there should be five people suspected of this. Among these people, one of them is Teacher Ozaki; the other is the same

In the office, Ms. Rina Higashiyama teaches badminton to everyone; it should be Mr. Tomio Yamayama, the manager of the sports venue; and Miki Suenaga, the former captain of the women’s archery club.”

"Why? Sister Yixin?" Conan was a little surprised. This must be suspected of committing a crime!

Guo Yixin expressed her thoughts: "Since you said that Mr. Ozaki asked you to investigate the matter, it is possible that he borrowed a sword to kill someone. In addition, the sword on the murderer's body is my lucky arrow.

'.So we are all suspected of killing him. Secondly, Miss Higashiyama Rina is the ex-wife of the victim Arata Harueemon. They are currently in a lawsuit over the custody of their son, and the person handling the case is lawyer Hiiri.

Conan and Kogoro Mori looked a little shocked, "The administrator, Mr. Michio Yamama, has a habit of peeping. He often climbs into the windows of the girls' changing room and the female physical education teacher's changing room. I heard that once, Mr. Yamagami was raped by Mr. Ozaki."

Catch Mr. Shintani. Suenaga-senpai is about to get married to Mr. Shintani next month, so there are rumors that she is the victim’s mistress, which has led to the breakdown of Mr. Shintani’s marriage with Miss Higashiyama.”

Conan shook his head slightly, looked at Guo Yixin, and said to them: "Then this is impossible! Look at the women's dressing room, it is clearly locked! Moreover, the center of the dressing room is separated by a brick wall, divided into

There are two rooms, but the wall is not built from the floor to the ceiling, but between the ceiling and the floor.

There is a gap of about fifty centimeters between them for ventilation. As long as you want to climb, it is possible to stand on the cabinet placed on the wall from the men's locker room and climb the wall to invade the women's locker room. I think that Mr. Shintani and Ozaki had previously

You must have been caught after seeing Mr. Shan do this!"

Mr. Shanshan exposed himself and nodded: "Little brother, you are right."

"Besides, there is one more thing I don't understand." Conan looked at them doubtfully.

Guo Yixin frowned. Reasoning was not her strong point, so she chose to reciprocate the favor at this time: "Oh? How is that strange?"

"It's just locked. Why is the women's fitting room locked, but the men's fitting room is not locked? In this way, wouldn't it be possible for anyone to enter the changing room? In other words, it is possible to

These five people should not be the only ones who enter here. Sister Yixin, why are you sure it was the five of you who killed Mr. Xingu?"

Mouri Kogoro looked at Conan, as if he was very angry that he was stealing the limelight, so he threw him aside, and then looked at Guo Yixin: "What do you think?"

"This is because the archery training ground is right on this road. Mr. Ozaki, that's right!"

Yutaka Ozaki nodded slightly, seeming a little passive. After Conan confirmed this, he nodded subconsciously. It seemed that in this case, the secret room technique must be solved first, and then we can check how the other party committed the crime.

But after that, the police investigation focused on who had borrowed the key to the women's dressing room. Conan felt that the possibility of that was too small. Moreover, the police also conducted research and felt that it was unlikely. The storage inside

There are no signs of movement on the locker.

Guo Yixin next to her was a little emotional: "I didn't expect that it was exactly the same as Higashino Keigo's secret room technique, but the fatal injury was different."

Conan was very surprised: "Keigo Higashino?"

"Yes, this is what my brother recommended me to read. The book seems to be called 'After School'!"

Conan immediately fell into deep thought. He had also read that book, but because the plot was too long and the story was not very suspenseful, he abandoned the book after reading the beginning. The book had actually been published a long time ago.

, and it is also the famous work of Higashino Keigo, which won the 31st Edogawa Ranpo Award.

"I think the murderer first killed the victim, Mr. Shintani, in the men's fitting room, then climbed to the women's fitting room, and then escaped from the previously opened women's fitting room. I just said

After asking the forensics personnel, there are indeed traces of dust on it that fell off due to climbing.”

"I think this is impossible, because if the lock is open, the key cannot be pulled out. And the police investigation found that the female fitting room was only used once by Miss Rina Higashiyama."

Guo Yixin exposed the impossibility of this matter.

"What if the murderer copied an identical key in advance?"

"This is impossible, because the key must be returned to the administrator's room after school, and then the administrator will conduct an inspection. If it is a replaced key, it will not be able to open the door here. This point,

You only need to investigate with the administrator to find out." Ozaki Yutaka looked at them, slightly helpless!
