Along the way, Lao Zhao introduced Fan Keqin and told him all the known information about the investigation these days. Fifteen minutes later, the two of them had already walked to Chaoyang Street, Fan Keqin stopped, and said, "Lao Zhao, can you see the supervision room here?" ”

Lao Zhao's name is Zhao Hongliang, and he is the captain of the first operation team of the field service group of the Intelligence Section. Fan Keqin belonged to his direct leader, so he immediately looked in one direction, and without raising his finger, he said, "It's an off-white three-story building about a hundred meters away." There are also other houses in the building, and in order to keep secrets, the personnel of the supervision room are all rented houses. Until now, the landlord didn't know that there had been a fatality. ”

Fan Keqin was still very satisfied with his style, so he looked at the gray-white three-story building, but he couldn't see the chimney and rain leak on it. said, "Let's go, let's take a look." ”

Saying that, the two of them walked to the front, Lao Zhao did not lead the way, but took the first step into one of the building doors, Fan Keqin followed behind, until he came to the third floor, Lao Zhao used the key to open a door on the left, and after entering the house silently, he closed the door.

Fan Keqin looked at the situation in the house, the square hall was not small, but there were sofas, coffee tables, and two beds, and there was no special equipment. Zhao Hongliang saw that there were no outsiders at this time, so he pointed to the door inside and said, "This is the bedroom, but it has been transformed into a monitoring room by us." ”

"Tuk tuk tuk - tuk tuk." Listening to the knock on the door, Zhao Hongliang said: "The code of three plus two is our people." With that, he opened the door, and sure enough, it was four members of the squad.

Fan Keqin looked at his watch, these people were still very punctual, and said, "The four of you are guarding here, and Lao Zhao will come in with me." ”

As he spoke, he walked towards the bedroom first, and Lao Zhao introduced to the side: "This guy must be a master of tactics, although our four detectives are technical talents, but they have also undergone a certain amount of military training, and they were all killed by this person before they had time to shoot a shot." ”

Fan Keqin took off his sunglasses, squatted down, looked at the four figures on the ground with an expressionless face, painted with lime, and stood up for a while before he said, "Have you determined the time of the crime?" ”

Zhao Hongliang said: "It is basically confirmed, according to the information provided by a neighbor downstairs, it was about half past three in the afternoon and four o'clock, and the other party heard a few slight sounds, but at that time he thought it was a small firecracker set off by someone outside, and he didn't pay attention." We judged that the other party might have used a silenced pistol. ”

Fan Keqin looked at the figures on the ground again, and then carefully looked at some of the chairs next to him, as well as the office desk, and the damaged monitoring radio on the table, and turned his head and said, "You're right." But these people died very strangely. ”

Zhao Hongliang was stunned and said, "Please instruct the team leader." ”

Fan Keqin said: "The result of our investigation is that the murderer is a master tactician, after special training, the whispering pistol used, these are all right, but you look at the way these people died, one of them was shot in the head with a gun, the other was shot twice in the chest, and the other was stunned first, and then shot, and the fourth was broken neck." ”

Zhao Hongliang couldn't help but flatter: "The team leader is really a good eye, Team Leader Zheng of the Operations Department at that time, after nearly two hours of on-site investigation, came up with the exact same cause of death as the team leader." ”

Fan Keqin said: "No! Although the way of death is the same, the order of death is different, which makes our investigation go in the wrong direction, you see! As he spoke, he pointed to the figure on his right and said, "This man was not the first to be killed, although he was closest to the door, but after the murderer entered, he was the first to repel him, and then killed the man lying on his side on the left, and he was the first to die." He was sitting and working, and had just taken off his headphones and was about to get up, when someone suddenly broke his neck. Then the killer quickly opened fire, killing the man on the right, shooting him in the head, and then killing the third person who had stood up from right to left, shooting twice in the chest, and finally killing the second person on the left, and the only detective who pulled the gun out. ”

After saying this, Fan Keqin looked at Zhao Hongliang, who seemed to understand something, and said, "What do you think?" ”

Zhao Hongliang frowned and said, "That'...... You mean, they know the murderer? "An intelligence department, if there is an internal ghost, is the most serious situation, so although he is an old agent, he still looks at Fan Keqin with some horror.

Fan Keqin was still expressionless, and said: "Yes, before I came, Section Chief Qian mentioned it to me, and he suspected that this was probably done by the ghost, and it seems that this is exactly the case." ”

Zhao Hongliang nodded approvingly, and said: "Then all this makes sense, after the investigation of the Operations Department, it was said that the murderer quietly opened the door by sneaking in, and then quickly entered the bedroom and killed four people in a row." And only one person had time to just draw a gun. But through the analysis that the team leader just made, that is, the person who came in was probably his own person, an acquaintance of the four brothers, so he didn't have time to fight back? ”

Fan Keqin said: "It's not just an acquaintance, I analyze that this person is also very likely to be the leader of these four people, the deceased on the far right, his chest is facing the wall, his right leg is bent, his waist and hips are lying on his side, his left leg is straight, look at the position of his right hand after death, nested in front of his chest, so he must have a movement to support the wall before he dies." This is not an action that can only be made by the person who died at the first time, but this person respects the murderer very much and walked in with him. Then the murderer immediately shot him back to the wall, and he would have such an action, so the previous person was standing in front of the murderer's right, obviously leading the other party into the bedroom. Therefore, who can make him stand in such a position and lead the way willingly? It must be a military rank, and the rank is higher than that of a certain commander of the other party. ”

Zhao Hongliang was surprised and said, "The team leader, this person you are talking about?" ”

Fan Keqin didn't speak, but beckoned to him, motioned for him to follow, and walked to the square hall outside, where the four agents were still guarding.

Fan Keqin looked at these people and said: "Captain Zhao, you immediately take two people back to the Intelligence Section, take all the members of your first team, in the Investigation Department, fifteen days ago, that is, on the day of April 5th, between three and a half in the afternoon, between four o'clock, is there any, no one who did not appear in the department at that time, there must be no omission, this person is 1.68 meters tall, to about 1.73 meters, between 30 and 40 years old, below the level of section chief, and above the captain." Arrest as soon as you find out! Do you understand? ”
