Yibin drove the two sisters to the house of Dr. Masaki Hirota in Shizuoka Prefecture. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Excuse me." The three of them went to Dr. Masaki Hirota's house.

"Oh. It's Mr. Bofeng, isn't it? I've heard my husband mention you. Come in, three. Dr. Hirota's wife, Noboru Hirota, came to the door to greet the three.

"Have all his guests returned?" Yibin asked casually.

"There happened to be a few batches of my husband's students who came to see him today, but now they have all gone back." Mrs. Hirota took the three to Dr. Hirota's study.

Knock knock~~

"Old man? Old man? Mrs. Hirota called out a few times, but no one responded.

"It's weird, I don't know what he's doing in there, and he locked the door." When Mrs. Hirota saw that no one answered the door, she planned to open the door directly. But the door to the study was locked from the inside.

Yi Bin used his mental power to sense the inside of the study, and found that there was a person inside who had fallen to the ground and was already dead.

He reached out and grabbed the edge of the air window bed above the study door, and pulled himself up with one hand. Looking through the air window, I saw inside the study, and sure enough, there was an old man who was crushed to the ground by the bookcase. Yibin pushed the air window with his hand and found that he had also locked it from the inside.

"Mrs. Hirota, do you have a backup key here?" Yibin let go of his hand and jumped off the wall.

"We don't have a backup key. The only key is on my husband. Mrs. Hirota replied confusedly.

Hear Mrs. Hirota's answer. Yibin kicked the door open without hesitation.

After the door was kicked open, several people saw Professor Hirota being crushed to the ground by the bookcase, staring at him motionless, and a lot of blood was still flowing from his head.

"Sir!" Mrs. Hirota saw her husband lying on the ground and wanted to go over to check on him. However, he was stopped by Yi Bin, who was squatting on the ground.

"Mrs. Hirota, your husband is dead. You'd better not come over now. so as not to damage the scene and affect the handling of the case by the police. ”

"Qiong, call the police."

"Hmm. Good. Gray Plains stepped aside and took out his mobile phone to call the police.

It didn't take long for Officer Yokozo from Shizuoka Prefecture to arrive with his men. Then the scene was inspected and evidence was collected.

"Officer Henggou, the cause of death is supposed to be caused by this ornament. Maybe it was when he fell down that he hit his head on top of this trophy, which led to his death. An forensic officer picked up a bloody trophy from the ground and handed it to Officer Henggou.

"Is that really the case? Masaki Hirota wanted to grab something on the shelf, but because he couldn't reach it, he stepped on the shelf. In the end, the entire bookshelf collapsed due to the loss of balance, and Masami Hirota also died because of his head smashing on this trophy. Officer Henggou looked at the bloody trophy in the forensic officer's hand, and then at the locked air window in the study.

"That's not right. Professor Hirota certainly didn't die by accident, but he killed him. Hearing that the police thought it was an accident, Yibin stood up helplessly. After all, listening to Gray Plains, Dr. Hirota should be good. Wouldn't it be too pitiful to be killed like this and the police decided it was an accident.

"Oh? You are. The wave of the wind that was with Mr. Mori last time? Officer Henggou looked at Yi Bin. suddenly remembered Yibin's identity.

"That's right, Officer Henggou."

"Why do you say he killed it? If he kills, then isn't this a secret room killing! Although he knew Yibin, Officer Henggou didn't believe much what Yibin just said.

"No, although this room is a lot like a secret room, it's just a scene that has been disguised by the murderer. Officer Henggou, come and see here. ”

"Look at this call. Although the killer covered the phone with a book to hide this important clue. But, don't you think it's weird? The phone fell from the cabinet to the floor, and it was turned upside down, but the receiver of the phone was still intact on the landline, do you think, is this possible? Yi Bin pointed to the landline phone that had fallen to the ground and was pressed by the book.

"yes, that's not normal." Officer Henggou looked at the phone that Yi Bin was referring to and fell to the ground.

"So, it's definitely not an accident, it's a killing!" Yi Bin said affirmatively.

"Who is it? Who the hell killed my husband? Mrs. Hirota grabbed Officer Yokomizo's hand and asked sadly.

"Ma'am. Please calm down. May I ask if there are any suspicious people who have come here to see your husband tonight? Officer Yokomizo grabbed Mrs. Hirota's shoulders to calm her down, and then asked.

"Including these three, there are four groups of guests here tonight." Mrs. Hirota pointed at Yibin and said.

"By the way, what are you doing here?" When Officer Henggou heard Mrs. Hirota's words, he looked at Yibin and asked curiously.

"Me. A friend of mine sent the wrong magnet to the professor, and I just came to help her get it back. That magnet should be right there on the computer desk. Yibin shrugged. Look at the computer that is sitting aside.

At this time, Xiao Ai was sitting in front of the computer and operating the computer.

"All the information on the computer is gone. The entire hard drive was formatted. Xiao Ai, who was operating the computer, said.

"Who is this little girl?" Officer Henggou asked angrily.

"Oh, this is my friend's sister, don't worry, Officer Yokogou, she's a genius and won't break a computer." Yibin explained casually.

"Little mourning. We don't play with computers anymore. You should stay with your sister first. Yi Bin walked over and hugged Xiao Ai and put her beside the dome.

And Xiao Ai, who was picked up by Yi Bin, quietly blushed.

"Officer Yokogou, don't talk about those things. Let's continue to see the scene. Yibin walked over and crouched next to the phone that had fallen on the ground.

Yi Bin turned over the phone that overturned the book and fell to the ground. The answering light of the phone was found to be on. So I pressed it.

"There were thirteen messages."

"Drip."

"Hey. Hello, I'm Shirakura. Professor Hirota, we made an appointment tonight, right? ”

Yibin pressed the pause button.

"Mrs. Hirota, do you recognize this Mr. Shirakura?" Yi Bin turned to Mrs. Hirota and asked.

"I've seen this Mr. Shirakura before, he's a student of my husband, and he's still very young." Mrs. Hirota replied.

Yibin, who got the answer, pressed the play function of the answering machine again. But it took a while for the recorded sound to sound.

"Drop"

"I'm Morioka, what time should I come over tonight?"

"I also know Mr. Morioka, he seems to be my husband's earliest student, and he often comes to our house to play." Before Yibin could ask, Mrs. Hirota revealed Mr. Morioka's identity.

"Uh. What did you send? A man in a white coat suddenly appeared at the door of the study.

"Who is this man?" Officer Yokogou asked, looking at the man.

"Oh, he's Mr. Shirakura. The guy in the recording of the phone call just now. Mrs. Hirota replied.

Yibin didn't pay attention to Mr. Shirakura, who had just arrived, but continued to listen to the recording in the answering machine.
