"Mr. Lin, there are 33 employees living in this building, except for those who asked for leave, there are 27 people. Today, they just held a patriotic education party and they were all playing upstairs." Liu Aizhong laughed.

"All twenty-seven people are upstairs?" Lin Xiao asked in a deep voice.

Liu Aizhong pointed at the two security guards and smiled: "About the same, the two security guards are on duty downstairs, and the remaining twenty-five people are upstairs."

Lin Xiao swept the roster, nodded slowly, and said in a deep voice: "Well! Manager Liu, lock the door of the building and ask the two security guards to guard it. No one is allowed to enter and exit. Let the others be concentrated in the top banquet hall. I think most of the killers are one of your employees."

"What?" Liu Aizhong was stunned. "Is there a killer among my employees? Mr. Lin, you won't joke, they are all workers who are solid. We have worked together for several years. How could they be killers?"

Liu Aizhong knew the situation of the thirty-three employees very well, including their family background and personality hobbies. They all seemed to be well-known. He didn't believe that there would be so-called killers among his subordinates.

"It's too early to draw a conclusion now. Let's gather the people first!" Lin Xiao said that, and walked through the crowd and headed towards the stairs.

The employees looked at each other and suddenly felt a little nervous.

Are there killers among them?

Even if I don’t believe this, I still feel gloomy when I say this.

Except for the security guard, the other twenty-five people were all concentrated in the banquet hall on the top floor.

The two security guards have been removed by Lin Xiao. At best, these two are accomplices, but they are by no means the killer himself.

Lin Xiao's attention was on the killer.

Men, women, young and old were scattered in the hall, sitting or standing, all their eyes staring at Lin Xiao.

Everyone was full of doubts about the so-called plainclothes that suddenly appeared.

"Manager Liu, what's the situation? Who is he?" A handsome young man with a very fashionable look stood up and looked at his cold and arrogant look.

Liu Aizhong quickly explained the whole thing to everyone.

When everyone was shocked when they learned that the police were coming to investigate the whereabouts of the killer.

"Are you sick? We've been dancing and singing upstairs. Who's the killer?"

"Is he here to make trouble? He's also a killer, are he making movies?"

"It's probably dazzled!"

"If the killer dared to climb over the wall, he would have been bitten to death by two pit bulls!"

Lin Xiao has been observing everyone's behavioral expressions.

There were twenty men and seven women in the hall. Except for the fashionable young man, everyone else was wearing brand new work clothes and looked in good spirits and nothing unusual.

Taking advantage of the discussion, Lin Xiao asked Liu Aizhong: "Manager Liu, are these all the people present today?"

"Yes, except for the two security guards downstairs, the other twenty-five people have been in the banquet hall and have never been out. Everyone can testify to each other about this, and there are absolutely no suspicious people." Liu Aizhong said confidently.

Lin Xiao frowned.

According to what Liu Aizhong said, the staff in the department have not changed, so is it very likely that the killer is not an on-duty employee, but an employee who is taking leave?

After taking leave, the employee killed someone, he secretly climbed over the wall and jumped back to the unit without realizing it.

Lin Xiao looked through the list of leave applicants again.

There were six employees who asked for leave, and Lin Xiao immediately flashed the three men and three women in the roster.

"Is there a surveillance outside the banquet hall?" Lin Xiao asked.

"Yes!" Liu Aizhong nodded quickly and pointed to the corridor behind Lin Xiao, "Look, it's there, you can monitor the entrances and exits, and someone can definitely record it when entering and exiting. By the way, I can check the surveillance on my phone--"

Liu Aizhong slapped his head, took out his mobile phone as if awakening, opened the video surveillance software, and the monitoring system of the entire building could be retrieved at will.

Lin Xiao looked at the surveillance camera at the door of the banquet hall. Within half an hour, except for a few people going to the toilet and returning quickly, there were no suspicious characters entering and leaving.

"Strange!" Lin Xiao whispered in his heart, "Why did the killer disappear out of thin air?"

Liu Aizhong carefully accompanied Lin Xiao and said with advice: "Mr. Lin, do you want to check every room?"

Lin Xiao handed the phone back and said in a deep voice: "I'll go check it myself."

"Okay! I'll accompany you!"

After Liu Aizhong told everyone not to leave in the banquet hall, he took Lin Xiao and searched the building one by one, and passed through every room, including the utility room and the toilet carefully.

One hour later.

All rooms have been inspected. With Lin Xiao’s meticulousness, if someone hides it, it is impossible to miss it.

Now even Lin Xiao was a little confused.

Even though I saw the killer climbing over the wall and entering the hospital, I was sure that the killer had entered the building, but I couldn't find any trace of the killer, and it was difficult to understand anyone.

"Mr. Lin, did you make a mistake? Maybe the sky is a little dark today, and you misread it?" Liu Aizhong ran around, feeling impatient for a long time, but he didn't dare to say it explicitly, so he had to ask tentatively.

"Impossible!" Lin Xiao said unhappily, turned around and walked towards the elevator, "Go and go back to the banquet hall!"

Liu Aizhong's expression was a little awkward, and he followed with his head down.

Except for the banquet hall, all rooms were inspected without any signs of hiding, and the killer broke into the building.

There is only one possibility, and the killer mingles among twenty-five people.

To put it more deeply, some of the twenty-five people must have left halfway, but no one noticed this detail.

Only by finding evidence of someone leaving can you find the killer.

Although Lin Xiao has not yet understood how the killer used a move to escape, he also understands that he met a master today.

Back at the banquet hall, Lin Xiao observed that everyone was in a low mood. No one could be happy when the party was disturbed.

Seeing Lin Xiao come back, the fashionable young man stood up suddenly and said sarcastically: "Hey! Mr. Holmes, have you found the killer?"

Everyone smiled knowingly, and this sentence "Shelmes" has brought ridicule to the extreme.

After more than an hour of tossing, he didn't even notice the shadow of the killer. Lin Xiao's performance made everyone think that he was just a clown and a joke.

Lin Xiao looked up and glanced at everyone in the banquet hall, and recorded their characteristics one by one in his heart. He did not take the ridicule of the fashionable man to heart.

"What's your name?" Lin Xiao sat on the sofa lazy and asked lightly.

The fashionable young man sneered, stretched out an arm to show Lin Xiao, and asked back sarcastically: "Mr. Sherlock Holmes, have you seen the roster? With your eyesight, can't you guess my name?"

"hehe--"

"Ha ha……"

His words caused everyone to laugh like a cheerful smile.

Lin Xiao had a faint smile on his lips and said quietly: "You can't say anything. Just looking at your arm, I really know who you are."
