"Are you sure you haven't met the informant's friend?" Xu Tian asked the barbershop owner.

"I really don't have an impression, there were quite a lot of customers in the store yesterday, especially after work, one after another customers came to me for haircuts, and I came into contact with so many people, I really didn't have any impression." The barbershop owner said.

"My friend came to your store in the afternoon, not after work." The informant said.

"How can you be so messy with people? I've seen so many people in one day, how can I remember them without a face? And your friend is still a man, and I don't even bother to look at the male guest. The barbershop owner said.

"Aren't there any surveillance cameras around here?" Xu Tian asked the police.

"Only the intersection of this street has traffic monitoring, so this case is very difficult to handle." The police said.

"Can I go into the barbershop?" Xu Tian asked.

"Of course, Officer Chen has already explained, you can help us solve the case." The police said.

After walking into the barber shop, Xu Tian found that the barber shop was a small room with no back door, no back window, and no bathroom.

"Are you sure your friend hasn't been out since he came in yesterday afternoon?" Xu Tian asked the informant.

"I'm sure." The informant said.

"Then why are you so interested in whether your friend has ever walked out of the barbershop? You're working at a chicken cutlet stall while you're looking to see if your friends are out of the barbershop, isn't that suspicious? Xu Tian asked.

"You...... What do you mean? The informant stammered.

"It's clear that either you're lying, or your friend is trying to avoid you and walk out of the barbershop." Xu Tian said.

"How could I lie, and if I had a problem, why would I report it?" The informant argued.

"There is some truth to what you say, but not all, any outcome can happen until the truth is ascertained. I'm just going to ask you one question, why are you keeping your friends so close? Xu Tian asked.

"Because I didn't want him to go, he came to me yesterday, we agreed to go back to my rental house to play cards after work, we couldn't play without him, but he was a little negative yesterday, saying that he didn't want to play cards, during which he found a lot of excuses to slip away, and I dragged them back, because I was about to get off work, around four o'clock in the afternoon, my friend said that he was going to get a haircut, I thought he was looking for a reason to slip away, so I stared at the barber shop opposite while working." The informant said.

"Very reasonable reason, but I think there must be a reason why your friend wants to slip away, until now, you can't contact your friend because it is possible that your friend's mobile phone has been dropped, and it happened that there was no one else in the barbershop at that time, and your friend's mobile phone was put away by the barbershop owner, and the truth should be like this." Xu Tian said.

"I ......" The barbershop owner seemed to be hit by Xu Tian's words, and began to stutter when he spoke. I did keep the person's phone secret, and I admit that the person did come to my shop yesterday afternoon, but he didn't get a haircut, so he sat with me for a while, chatted with me about something and left, and I also heard the phone ring before I thought of keeping his phone secret. ”

"Then the truth has been solved, your friend's phone has been dropped, so you can't contact him, I'm sure you'll be able to see your friend soon, and he will definitely come looking for his phone." Xu Tian said.

"If that's the case, then he should have come back to find his phone a long time ago!" The informant said.

"Maybe he came back yesterday after you got off work." Xu Tian turned his head to look at the barber shop owner. "You tell you the truth, after his friend left yesterday, until the police came, did his friend come back to find his phone?"

"Nope! I'm also wondering why I didn't come back to find my phone, but I've always been glad that if he didn't come back today, I could have sold my phone with peace of mind. The barbershop owner said.

"Didn't come back to find your phone? That means he doesn't know where the phone was dropped, and if that's the case, it's possible that the person has been to other places since he left here, and he has been to too many places, so he forgot where the phone was dropped? It seems far-fetched to say this, because if the phone is lost, it will be very inconvenient to life, and he must want to find the phone as much as possible, but why didn't he go back to the barber shop to find it! Xu Tian inferred to himself.

"Behold! Let's go to the missing man's house and have a look! Maybe you can get some information. The police said.

Now it can only be like this, under the leadership of the informant, Xu Tian and the police who handled the case walked through the streets and alleys to a private house, this private house is also a rental house, there are other residents in the yard, and the house where the missing person lives is on the second floor of two small buildings.

The missing man's room was filled with the smell of mold, dust and garbage everywhere, and the floor tiles looked like they hadn't been cleaned in months, giving it a very depressing feeling.

"Oh my God! Is this still a place where people live!! The police sighed.

"If this person didn't come back to sleep yesterday, then it must be investigated, and the clue is also very important because the reporter has been staring at the barbershop opposite yesterday, and how the missing person came out of the barbershop." Xu Tian said.

"Yesterday afternoon, around four o'clock, at that time I remember that there was a civil dispute in the vicinity, but it was not me who caused the case." The police said.

"You mean to say that there's something that grabs the reporter's attention? So the missing person took advantage of that gap to walk out of the barbershop? Xu Tian asked.

"It's possible! But I think the whereabouts of the missing person are more important, and no matter what happened in the barbershop, the person is indeed missing now. The police said.

At this time, the other policemen in charge of the visit came back, and by questioning the residents in the courtyard, it was determined that the missing person did not come back last night, so this case became a real missing case.

But Xu Tian couldn't figure it out, something must have happened in the barbershop, either the informant was lying, or the barbershop owner helped the missing person walk out of the shop, and one of those two people must have a problem.

The mobile phone kept secret by the barbershop owner can almost mean that the barbershop owner did not help the missing person get out of the shop, but it is also possible that after the barbershop owner did something, he found that the missing person's mobile phone rang, and the barbershop owner must have been very nervous at that time, and in a hurry, he received the missing person's mobile phone?
