Hiroshi Kato nodded and said, "It's me! You've come to see me about Yoshiko Nishimura's case, right?"

Guan Feng said, "That's right! We also deeply regret what happened, but the dead cannot be brought back to life. Finding the murderer as soon as possible is the best way to comfort her. Are you available now? We would like to ask you some questions, mainly about Nishimura Miko."

Hiroshi Kato nodded and said, "Convenient! I've been dreaming of bringing the murderer to justice."

Guan Feng said, "If it's convenient, shall I come to your room?"

Kato Hiroshi was taken aback for a moment, seemingly not expecting the suggestion to go to his room, but his expression quickly returned to normal, and he invited, "Then let's go!"

Guan Feng, Gao Dacheng, and Qi Xia followed.

The group entered room 202.

The room was tidy.

Spotless!

This was Guan Feng's first impression.

In all the time he'd been investigating cases, only Li Qiangwei, the first criminal suspect to come to Hua'an, had given him this impression.

Generally speaking, people with this kind of obsessive-compulsive disorder about cleanliness have some unknown life experiences.

Guan Feng made his first judgment.

He looked at Hiroshi Kato and asked, "Mr. Kato, do you usually live here alone?"

Kato Hiroshi's eyes darted around for a moment, then he nodded frankly and said, "Yes, I usually live alone!"

Looking at the other person's expression, Guan Feng reminded him, "Professor Kato, now that a murder has occurred, we have an obligation to remind you. If you deliberately mislead our police investigation, we will pursue relevant responsibilities, even criminal liability!"

Although Kato Hiroshi's eyes showed a hint of unconscious panic, there was no fear in them. Instead, he asked, "What do you mean by that? Are you threatening me?"

Guan Feng said calmly, "It's not a threat, I'm just reading out our rules and regulations to you."

Hiroshi Kato's expression behind his glasses was somewhat gloomy.
