Apparently. It would take a lot of manpower and material resources to find out the perpetrators from among the hundreds of people, and it would be impossible for the special investigation team to find out the perpetrators with three heads and six arms.

The only shortcut is to rely on the existing evidence and information, and use logical reasoning to narrow down the scope of investigation, starting with the most suspicious targets.

"When my teacher left, he left me four sentences, he thought that this person arson case has four major characteristics, jihua thorough, ingenious links, clear division of labor, backfire, please note zuihou two sentences, contrary to wishes, it means that the purpose of destroying the corpses envisaged by the planners has not been achieved, and the bodies of the four deceased are basically intact, which provides the most important clues for our investigation work, and the other sentence, the clear division of labor, is an important guiding direction for our current investigation work, I think, we can draw such a conclusion, In addition to the masterminds behind the scenes, there are also the on-site commanders and perpetrators of the arson, and the three form a complete criminal chain. ”

Yu Zhonghao pondered: "You mean that the arson was committed by the staff of the teahouse, the commander was someone in the management of the teahouse, and the mastermind behind the scenes was a certain or several guests who were staying in the teahouse at the time. ”

"I agree with this inference." Xiao Jiannan nodded.

Yu Zhonghao looked at Xiang Tianliang and said: "As for the mastermind behind the scenes, it is a certain or several guests who were staying in the teahouse at the time, this is just a hypothesis, what evidence do you use to prove this hypothesis." ”

"First, the whole case did not start with the fire at 7:43, but from the four deceased people entering the teahouse in the afternoon, and the teahouse is not the best place for good drinkers, so who can leave the four deceased in the teahouse for more than five hours to welcome the arrival of death? Can the people in the teahouse do it, can the people in the management of the teahouse have such a deep friendship with the big boss from the capital, obviously not, only people who have an important relationship with the deceased can do this, it is this person who planned and manipulated the entire arson case, and successfully made the four deceased stay in the teahouse and wait for death. ”

Yu Zhonghao smiled: "Your reason can only be regarded as barely established." ”

"Second, since it was a big adventure, the wisdom of the mastermind behind the arson case was very accessible, and he took an unexpected decision in this case, that is, to put himself at the scene of the fire, so as to become a victim, and then successfully escape, the barbed wire fence in the river and the temporary safety staircase, didn't he also prepare for himself?"

Xiao Jiannan nodded and said, "I agree with this." ”

"On what basis do you agree?" Yu Zhonghao asked.

Xiao Jiannan said: "Five years ago, I met a criminal like this, that guy has a high IQ, bold, after killing someone, not only did not run, but drilled into the scene to watch the lively crowd, I have dozens of people, as a matter of course, to chase on the road, but people are not in a hurry, and after eating a bowl of noodles in a noodle restaurant between the street from the scene of the crime, he left calmly, damn, and later caught the first trial, only to know that he was standing behind me at that time, but three meters away, and he was still carrying a knife used in the crime, I was so angry that I slashed him hard. ”

"Third, such a big jihua, the core lies in killing, killing people, destroying corpses, the mastermind behind the scenes will not rest assured that his subordinates, or the people he hires, from a psychological point of view, the fool's IQ is close to zero, the simpler the mind, the more unscrupulous he is, and the higher the IQ of the person, the more suspicious he is, the more he is worried about his jihua, the more hands-on he is at the critical moment, have you ever seen the boss on the underworld, do you often do it yourself when you kill people and sell goods, very few, but only people with high IQ, If you are not a professional criminal, you will not be at ease with your jihua, so you will come to the scene in person. ”

Yu Zhonghao's face was grim, "And it is very likely that this guy who came to the scene in person, there is someone behind him, and he is just an executor, so he should be there in person, not to mention that he knows that the fire burns the fastest and fiercest, and he himself can't die." ”

Xiao Jiannan said: "Then confirm this hypothesis as a fact, the mastermind behind the scenes is in the teahouse, let's go to find someone according to this assumption first." ”

"I agree." Yu Zhonghao nodded.

Xiang Tianliang walked back to the blackboard and wrote a line of words in chalk: Where is he?

Xiao Jiannan said with a smile: "It's impossible on the first floor, for him, a fire will be safely evacuated, and there is no cover meaning." ”

Yu Zhonghao moved quickly, pulled up against a large pile of file bags on the table, and quickly pushed some of the file bags to the ground.

"Now, on the table are the information and inquiry records of the guests in the 96 private rooms from the second floor to the fifth floor."

Xiao Jiannan got up, picked up a few file bags from the table, and said while throwing them: "Yu Zhonghao, you don't make sense, I was in the No. 406 private room that night, Xiao Xiang was in 301, Xie Ziheng was in 302, and there were two private rooms 210 and 212, as well as four unlucky ghosts waiting for 211, they can't be regarded as the masterminds behind the scenes." ”

Yu Zhonghao asked: "Since you have already decided that Xie Ziheng is not the object of suspicion, then why do you still ask him." ”

Xiao Jiannan pointed at Xiang Tianliang and smiled, "Xiao Xiang said, I have the right not to use it, and it will be invalid when it expires, so take this opportunity to take revenge." ”

"You two guys, insidious, too insidious." Yu Zhonghao couldn't cry or laugh.

Xiang Tianliang said: "Just let Xie Ziheng lead by example, there are still some people who have not been asked, with Xie Ziheng as an example, they don't dare not come." ”

"Nonsense."

Xiao Jiannan threw a few file bags, clapped his hands and said, "From the second floor to the fifth floor, there are still ninety private rooms to be investigated." ”

Xiang Tianliang said: "Now, you take out all the people who left before 7:30, the fire should be burned after 7:30, and it should have nothing to do with them." ”

Yu Zhonghao and Xiao Jiannan were busy again, picking out seventeen file bags from the pile of files.

Seventy-three remaining.

"Next, find out and throw away all the women in the private room, and none of the men over the age of thirty."

Another round of rummaging, and in accordance with the above two requests, a total of twenty-one file bags were thrown to the ground.

There were fifty-two file bags left on the table.

"There is no Qinghe native in the private room, so let's remove it."

There are not many people who meet this condition, only five.

There are also forty-seven portfolios.

"Men in the private room, only have a junior high school education or less, please remove them for the time being."

There are only four.

There are forty-three private rooms left.

"It wasn't booked over the phone or otherwise, it was a random selection of rooms, not the people we were looking for."

Xiao Jiannan flipped through for a while, and pulled out seventeen from the pile of files one after another.

Yu Zhonghao was a little skeptical, "Is this reliable?" ”

Twenty-six file bags remained on the table.

"Take away those who don't have a teahouse VIP card."

This time, Yu Zhonghao picked it up, and took a total of eleven of them.

There are only fifteen portfolios.

Xiang Tianliang smiled slightly, "Among the guests, those who have not been in business, have not been in politics, and have not joined the army can also be removed." ”

Xiao Jiannan was easy to find for a while, "Damn, fortunately, the original task force was quite careful, otherwise how could I find this." ”

He took four more file bags from the table and threw them on the floor.

Eleven more.

"Okay, I still have two conditions here, all men's private rooms, and private rooms with three or more men, we don't need to check them for the time being."

Yu Zhonghao hesitated, Xiang Tianliang's direction was very clear, and the rest were all people with heads and faces, either doing business or belonging to public officials.

Xiao Jiannan buried his head again, and removed a total of six.

On the table, there are also five file bags.

Xiang Tianliang pushed the five file bags in front of Yu Zhonghao, "The guests in these five private rooms have not made a record of the inquiry, and the management of the tea house has not made a record of the inquiry, can you complete it in five days?" ”

"That's fine, but are you sure we're looking for someone in these five bags?"

Xiang Tianliang shrugged his shoulders, sat down on the chair, crossed Erlang's legs, pointed to his head with a finger, and said with a smile: "I can't confirm it, but I think they are the most suspicious, I have a net in my head, and I have long put them in the net." ”

"What net? Fish nets, or shrimp nets? Yu Zhonghao scoffed.

"The Web of Logical Reasoning." Xiang Tianliang's face was complacent.

Xiao Jiannan scratched his head and said suspiciously: "Xiao Xiang, I believe you, but I also think that the conditions you said are a bit too vain, I haven't caught up with the good times, I don't read much, and I really don't understand ......"

"Actually, these are all things you usually use to solve crimes, to paint a portrait of a criminal, and I am a portrait of the mastermind behind the scenes, painting a virtual image, this person has courage, is likely to have been a soldier, this person has a high IQ, is likely to have a high level of education, this person is going to kill a businessman, is likely to have done business, this person is confident that he can characterize the fire as an accident, is likely to be a public official, this person can come to the scene in danger, has a strong psychological quality, is likely to be a man, and is a man over thirty years old, This person chooses Qinghe Teahouse to kill people, it is likely that he is a frequent visitor to Qinghe Teahouse, and has a VIP card, this person can find helpers in the staff of the teahouse, and let the teahouse 'prepare' stairs and barbed wire, it is likely to be a local, this person has a high IQ but is suspicious, so he will not bring more people with him, more than three people, he will be afraid of jihua leakage, he has to choose his best location, in the current teahouse business season, he can only book a room in advance......"

Xiao Jiannan listened to it and said with a smile: "As soon as you say this, I think it makes a lot of sense, just listen to you, and I'll go and touch the situation of those four unlucky ghosts again." ”

Yu Zhonghao also said: "I hope your inference is correct." ”

"Hehe, if I'm wrong, I'm not the head of this special investigation team, and I'll step down automatically."

"Phew, who's to admit you're the leader?" Xiao Jiannan kicked Xiang Tianliang.

Xiang Tianliang winked and said mysteriously:

"You guys wait and watch the show, as long as the two of you complete the task, I can find the person we are looking for in three hours."
