"I think," Conan squinted at the lock that Chiba was paying attention to. "We might be able to find something in the teacher's lounge on this floor."

"Why do you think that?" On the way to the lounge, Officer Twilight asked, and Chiba pricked up her ears, ready to listen to Conan's reasoning.

"This is the third floor, a very ordinary floor." Conan explained as he led the way. "The autopsy report showed that the time of death was in the middle of the night, when the entire school building was closed. If Kiriko didn't know that the school building would be closed, she would choose to run all the way to the first floor, and even after finding that the door could not be opened, she would never choose to go back upstairs, but would choose to hide from the murderer on the first floor. So Kiriko should be well aware that the school building is closed. Then, she will most likely run to the nearest place to lock it. That's it, the Faculty Department. ”

"So, she must have escaped from a room on this floor." Qianyu was thoughtful. "At the same time, the murderer is likely to be the teacher here, so you say that the teacher's lounge might be able to find something?"

"yes," Conan said as he approached the door of the break room and pushed it open. "We... Conan's brow furrowed slightly. "I don't feel right...

The whole room is a rectangle, with a long table in the middle, and at 5 o'clock is the direction of the door where Conan and the others are standing.

"I don't think something is right, too," Chiba pointed to something on the table. "It's obvious, but it's weird, isn't it?"

On the table, two plastic paper cups stand out, apparently two people once sat here. It appears that one person is seated at the head of the long table, and the other is seated to his left. Considering the previous reasoning, it is obvious that the murderer and Kiriko once sat here, and as long as they check the fingerprints on the paper cup or the saliva on the water cup, and then compare them with the teachers in the school, they can confirm who the murderer is.

"Yes," Conan mused, walking over to the two cups. "Since he has time to kill, why not clean up these traces? If it's a teacher, even if you carry Kiriko out of school and drive it to the field to throw the corpse, it's feasible! ”

"Killing... Qian Yu suddenly remembered something. "Wait a minute... I remember... Toya Tetsuko! ”

"What?" Officer Twilight on the side was a little stunned. "Tetsuko Toya? The deceased? ”

"Oh my God!" Conan immediately understood what Chiba meant-the man next to Toya Tetsuko who called himself "Sugiyama Shigo" was pointed out as a living person by Toya Tetsuko Sensei himself... In the same school, at the same time, two rare big things that happened were mostly related to each other. If Toya-sensei was involved in this illegal school case.,And because of this, people who are very similar to her are killed.。。。 The murderer is that "Sugiyama Shigo"!

"Officer Twilight," said Chiba to Officer Twilight at once. "Please immediately investigate whether there is or has been a male teacher surnamed Sugiyama at Kakudo Elementary School and Teidan Elementary School, please do it as soon as possible! We have something urgent, so let's leave first! ”

"Officer Twilight," Conan said in a more detailed manner. "You'd better send a police officer with us to the hospital to watch out for emergencies that may arise."

。。。

Conan's fears came true, and just after Chiba, Conan, and Officer Takagi arrived at the Yonhua Central Hospital together, they heard a commotion as soon as they entered the door, and from the duration of the sound, it seemed that it was loud and came from a long distance. (The more you shout, the longer the voice drags on.) ）

"You are illegally detained!" Chiba and Conan ran to Gregory's office, where the sound came from, and saw "Sugiyama Shigo" standing in front of Gregory, slapping the table and yelling. "Her injuries have recovered, and as her family, I have the right to do so!"

"I'm a doctor," Gregory stood up with his cane. "I'm telling you explicitly, she's not recovering!"

"I already know from your nurse," "Sugiyama Sensei Go" continued to question. "Tianzi has been healed! Now you're blocking the news and trying to make me spend money! ”

"You call the nurse out," Grigory said calmly. "I'd love to talk to her."

"I'm not going to give you a chance to make her lose her job!" "Sugiyama Division," he roared. "In the name of human rights, I want to discharge Tianzi from the hospital!"

"You're talking about human rights here?" Conan couldn't help it, pushed the door in, and accused "Sugiyama Shi go". "Do you still have the face to talk about human rights here? You bloody executioner! ”

"What?" "Sugiyama Division go" was stunned. "How are you? What are you talking nonsense here? ”

"Nonsense? Justice is at ease in the hearts of the people! By the way, you also don't have the option to be discharged from the hospital with Miss Patient! Qian Yu looked at the farce in front of him, and also walked to Conan's side, sneering. Mr. Sugiyama. ”

"Oh~" Gregory glanced at Officer Takagi behind Chiba and Conan. "Looks like you've got a good helper with you."

"Officer Takagi," Conan said. "The man claimed to be the boyfriend of the patient, 'Tako Toya', and asked for Tako Toya to be discharged immediately. But we've already spoken to the sober Tsuya Tako before, and she told us that she was our former teacher, the deceased in the secret room of the Teidan Elementary School, Tetsuko Toya. ”

"Huh?" Officer Takagi was clearly still a little confused.

"So, this gentleman didn't take away the power of Toya-sensei, besides," Chiba took Conan's words. "We apply for patient protection. At the same time, Officer Takagi, we would like you to bring this Mr. Sugiyama Shigo back to the Metropolitan Police Department as a suspect! It is very likely that he was involved in the entire illegal school case, and it is even very likely that he was the murderer of the murder that happened in the secret room of the Didan Elementary School! ”

"These two little ones are talking about something inside, at least the part about the identity of the patient," Grigory said, turning his cane. "I've also talked to Miss Toya, but she's not Miss Toyadako, and Miss Toya doesn't know this person. I didn't call the police because I didn't have physical evidence that Miss Toya wasn't Miss Toya – and we didn't try to test the gene bank like we did in the UK. If the Metropolitan Police Department believes this guy, I won't be able to protect Miss Toya Tetsuko. ”

"Take him back, Officer Takagi." Conan said lightly. "Trust me, there's nothing wrong with that."

"Uhhh Officer Takagi hesitated for a moment, but took out the handcuffs. "Mr. Sugiyama, please come back to the Metropolitan Police Department with me."
