Feng Bujue said, "You can call me, uh... Mr. F."

"Damn it..." Tachibana cursed and moved toward Feng Bujue. By the looks of him, it was very possible he'd pounce and start throwing punches.

Doctor Watanabe held him back with one hand and said to Feng Bujue, "Mr. F, do you know where Officer Yamada's body is?"

Feng Bujue said, "I don't know. I don't know who Yamada is, but I can roughly guess what happened."

"Is that so... Then, Mr. F, does Hirata know of your existence?" Watanabe asked again.

"Before... he shouldn't have known of my existence, but at this moment... I'm not sure anymore," Feng Bujue replied. "I only have some vague memories of the crimes Hirata committed, so I have some questions I'd like to ask you, Doctor Watanabe."

Tachibana shouted from the side, "Doctor! This kid is clearly making up a name on the spot, claiming to have schizophrenia to try and get away with it!"

Watanabe said, "Determining the authenticity of these symptoms is within my scope of work, Inspector. Please trust me and allow me to do what I need to do."

"Tch..." Watanabe walked out of Feng Bujue's sight again and stood in a corner in the back, and soon the sound of him lighting another cigarette came.

Watanabe took a breath and said to Feng Bujue, "What do you want to ask?"

"Um... Excuse me, was I watching a video the whole time just now?" Feng Bujue asked.

"Yes," Watanabe replied.

"Why did you make me watch the video?"

Watanabe stared into Feng Bujue's eyes, organized his words, and then replied, "You... no, Hirata-kun showed severe signs of delusion after being arrested. He insisted that he had not killed anyone." He paused. "He told the police that he had only killed a monster."

"Are you here to determine if Hirata is truly mentally ill?" Feng Bujue asked.

"Yes."

"What was that film you showed me just now?"

"It was filmed with the police's assistance, a reconstruction of some relevant segments," Watanabe replied.

"Did you show it to me in reverse chronological order?" Feng Bujue asked.

Watanabe was taken aback. "Yes, this makes it easier to awaken your..."

Before he could finish, Feng Bujue interrupted, "Can you show it to me again in chronological order?"

Watanabe and Tachibana exchanged glances. The latter was furious and didn't want to speak, only nodding slightly.

Watanabe walked to the desk, operated it a few times, and the projector started running again.

"Doctor, can you take off this tape so I can blink?" Feng Bujue said.

"Okay," Watanabe readily agreed. He didn't recommend doing this in the first place, but the previous Hirata Hideichi would shout in shock and close his eyes tightly as soon as he saw the image on the wall, so Inspector Tachibana had made things into the current situation.

Feng Bujue had already sorted out some clues in his mind, and he now needed more clues to corroborate his reasoning.

The video started playing. The picture was in black and white. There were no speakers or anything like that next to the projector. Apart from the clicking sound, there were no other sounds. Of course, no sound was needed.

The content of the video was very simple, and the length was actually very short. It was just a reconstruction of a few key segments to help the insane Hirata Hideichi recall, and the actors were all people from the police station, filmed by Doctor Watanabe.

The first segment of the video, the first scene, was in Hirata's company. The camera started by filming Hirata's desk for a while; the next set of shots was in the stairwell, with a man and a woman embracing and pretending to be intimate; the third scene was in the toilet, with two men smoking and talking.

"This segment is reconstructed based on the testimonies of two of Hirata's colleagues," Watanabe explained from the side. "They said that Hirata heard their conversation in the toilet that day, which may have led to the motive for the murder."

Feng Bujue nodded as he watched attentively. The second segment started soon, and it was also the most crucial segment.

The camera first filmed a panoramic view of a Western-style house, showing the address on the house number, 4-5 Rokubancho. In front of the Western-style house was a garden. The second scene was the interior of the Western-style house, the empty hall, and a staircase leading to the second floor. The third scene took place in the room where Feng Bujue saw the monster. The plot recorded in this third set of shots was: a police officer playing Hirata, holding a fake pistol, pushed open the door and walked into the room. A female police officer played Haruko, lying on the bed. Another person played the section chief. When he saw the person with the gun come in, he stood up from the bed in panic, saying something while going around the bed, wanting to snatch the gun. Then the actor playing Hirata pretended to shoot and kill him.

"This is the general course of the incident. Since there were no witnesses..." Watanabe turned his head to look at Feng Bujue again, "And Hirata-kun's confession cannot be adopted, so we can only speculate on the general course of the incident based on the on-site investigation."

"By the way, what's the name of the deceased..." Feng Bujue asked.

"Fukui Shinichiro," Inspector Tachibana's deep, hoarse voice came from behind, "He's your immediate superior in your company."

The video soon reached the third segment. The content of this segment was first a person playing Hirata asking a passerby for directions.

Watanabe said, "The witness said that Hirata asked her how to get to Sanchome that day. At first, he was very calm, but suddenly he showed a panicked expression. I think that at that time, Hirata-kun's spirit was already on the verge of collapse. Not only did he forget his address, but he also began to hallucinate."

The next shot in the video showed a nagaya (row house), and the person playing Hirata walked in and closed the door. The next shot was a police officer bending over to knock on the door.

Watanabe then said, "The old woman next door heard Hirata shouting in the evening, so she went over to knock on the door to inquire, but Hirata replied that he had not shouted." He paused. "But the old woman saw a strange shadow from the opened crack in the door, so she called the police.

"After the police arrived, they found Haruko's body hanging from the roof beam, while Hirata was calmly sitting at the table drinking tea. The police found Officer Yamada's missing pistol in the row house."

The video ended here, and the room fell into a brief silence.

Inspector Tachibana, who was still standing in the back, broke the deadlock: "So, Mr. F, are you satisfied now? Quickly tell us Yamada's whereabouts and confess your crimes obediently." He said impatiently, "Or... are you going to pretend to be amnesiac again and call yourself Mr. A or Mr. B?"

Feng Bujue ignored him and fell into deep thought. After a full five minutes, he finally asked, "What's the date today?"
