A corner of the ballroom.

Shu Yunwen and Shiratori Ren Saburo stood together, frowning: "...... So, don't you police have any clues right now?"

"yes!" Shiratori nodded, "...... Although we mobilized a lot of manpower in the search class, after all, it has been a year since the case, and it is very difficult to investigate again, and it takes a lot of police resources just to sort out Nishino's interpersonal relationships. So far, the only progress we have made is to completely rule out the suspicion of Minister Odakiri and Toshiya......"

"Hmm, is it?" Shu Yunwen pinched his chin and turned his head to look at Oda Kiritsu not far away—

When he had just entered the banquet hall before, Oda Kiritoshi also came forward to greet him......

"Didn't you say before that your police still have a key suspect? Have you found him?" Shu Yunwen asked again.

Shiratori shook his head and said, "...... Not yet. Since the day before yesterday, Yu Chengzhen has lost his trace and has never been found. However, some witnesses said that he had been present at the scene of the murders of Officer Narazawa and Officer Shiba, so his suspicion now can be said to be the most serious...... You see, this is the photo of Yoo Sung Shin......"

As he spoke, Shiratori handed Shu Yunwen a photo.

Shu Yunwen took the photo and looked at it, then groaned, and suddenly asked, "By the way, what about that scumbag Yabe Shindo?" Did you ask any clues from his mouth?"

"Uh...... This ......" Officer Shiratori twitched the corners of his mouth twice before replying, "...... Mr. Yabe is still in a coma, so he can't give us any clues to the police......"

"He's still in a coma?" Shu Yunwen was stunned when he heard this, "...... Is his injury that bad?"

It is said that the day before yesterday at the open-air restaurant of the Rice Flower Hotel, although Yabe Mamichi looked miserable, he was not fatally injured at all......

Could it be that after this guy went to the hospital, he had a new "adventure"?

Shu Yunwen was surprised, and Officer Shiratori said with a dry smile: "...... His injuries weren't too serious, but his luck wasn't very good......"

"Bad luck, what do you mean?" Shu Yunwen asked.

Officer Shiratori replied with a strange expression, "...... You must remember the Mr. Inada who commissioned Detective Koshisui to investigate Yabe Mamichi, right?"

"Of course I remember!" Shu Yunwen nodded - in other words, the woman who was beaten by Yabe Shindo and had a miscarriage was the client's sister!

“...... Mr. Inada is a surgeon......"

The white bird said faintly, Shu Yunwen heard this, the corners of his mouth couldn't help twitching twice, and then a black line appeared in his head:

"Uh...... Don't tell me, the person who helped Yabe Shindo with the operation happened to be Mr. Inada......"

Shiratori nodded silently, and then said, "...... It was really him! Yabe Mamichi went to the operating table and almost couldn't get off, but then I heard the nurse secretly say that Dr. Inada's sister had been beaten and miscarried, and suddenly felt that something was wrong, so I saved one of Yabe's lives......"

"Well, that's a ...... Retribution!"

In other words, is there anything more tragic than having surgery and being planted in the hands of the enemy?

Yabe Mamichi is just unconscious now, that's all good luck!

Shu Yunwen was quite emotional, and then turned his head and asked Shiratori, "By the way, how is that Mr. Inada now?"

"He is now temporarily detained by our police, but he does not admit that he is retaliating and insists that it is just a medical accident......" Officer Shiratori said softly, Shu Yunwen immediately nodded:

"That's right, that's right, I can't admit it, if I go back to a lawsuit, I'll help him find a good lawyer, and I will definitely help him get rid of the crime...... Hmmm? Xiaolan's mother, the concubine lawyer, is also here? The concubine lawyer is a big name in the legal profession, why don't you ask her for help?"

"Uh......" The corners of Officer Shiratori's mouth twitched, and he looked at Shu Yunwen speechlessly-

In other words, Shu Yunwen, have you considered my feelings when you said such illegal things in front of me?

Officer Shiratori coughed lightly, then interrupted Shu Yunwen and said, "Lord Yunwen, let's talk about Mr. Inada later...... Although there is still an hour before the official start of the engagement feast, the person in charge of the registration at the door told me that all the guests have arrived, so I would like to ask you to help see if there are any suspicious people here......"

"Suspicious people?" Shu Yunwen was stunned for a moment, then raised his hand and looked at his watch, "...... Okay, then I'll show you it, but I can state it in advance, and I can't necessarily see it......"

If the murderer had been exposed to the sun for a long time yesterday or today, the yin and ghost qi on his body would probably have all dissipated, so Shu Yunwen was not very sure about this.

"Anyway, please!"

Officer Shiratori bowed slightly towards Shu Yunwen, his eyes were cold: "...... Today is my sister's engagement banquet, and our Shiratori family will never allow anyone to make trouble at this time!"

......

Inside the banquet hall of the engagement reception.

Koshisui Nanatsuki was wearing a waiter's uniform, deliberately pasting a large piece of gauze on his nose to cover part of his face, and holding a tray of drinks in his hand, wandering among the guests, his eyes looked at Shu Yunwen and Officer Shiratori who were chatting in the corner from time to time-

The night before yesterday, although Shu Yunwen refused to tell her any facts of the case, she still relied on her own channels to find some clues and guessed that someone was deliberately killing the police!

The reason why she is here today is also because there are a lot of police officers at the engagement banquet this time, and the murderer is likely to get involved......

Nanatsuki Koshisui was shuttling through the crowd, and suddenly, Nanatsuki felt that someone had pulled the corner of her clothes, and then heard a familiar voice:

"Hey, Sister Yueshui, why are you here, and you're still dressed like this......? Did you sneak in?"

"Uh......" Nanatsuki Koshisui heard this very familiar voice, the corners of his mouth twitched twice, and then he hurriedly looked down at Conan and made a silent gesture:

“...... Conan, you little ghost...... How did you find me?"

"It's very simple!" Conan replied with a smile, "Of all the waiters in this banquet hall, you are the only one who deliberately covered part of your face with such a large piece of gauze, and those who are not familiar with it will probably think that you have been accidentally injured, but those who are familiar with you should be able to recognize you if they take a few careful looks......"

"Uh...... All right. Nanatsuki conceded defeat, and Conan asked expectantly:

“...... Sister Yue Shui, what are you doing here today? Are you investigating? What you want to investigate is probably a case of two policemen being killed in a row, right?"

"Hmm, do you know about this case too?" Nanatsuki Koshisui was slightly stunned, and then replied with a smile to herself, "...... I almost forgot, you little devil is super fond of reasoning, and it's normal to know this case......"

Koshisui Nanatsuki said, his tone paused for a moment, "Hey, Conan, don't you want to investigate this case too?"

"Uh-huh!" Conan nodded seriously, "I do want to investigate this case, after all, I am an eyewitness to the first case......"
