Qiao Yan couldn't help but think of the kiss last night, and suddenly felt cramped, confused, and nervous. "That ......," she found the topic, "do you think Hong Bingwei really doesn't know the whereabouts of that painting?" ”

Yu Chihong moved his body slightly. "What kind of painting you're talking about, I don't know."

"Don't pretend." Qiao Yan exposed him, "You don't know the painting clearly, can't I still see it?" Don't forget what I'm studying. ”

"Oh?" Yu Chihong's eyes lit up, and a smile actually spread on his lips. "In this case, can't you tell if Hong Bingwei is lying, and why are you asking me why?"

Qiao Yan glared at him. "Why can't you tell me something you know?"

"There are some things that you can't share with others." The smile on Yu Chihong's lips disappeared, "When Hong Bingwei spoke......

"Are you trying to say that the eye moves to the upper right corner?" Qiao Yan snatched the conversation.

"You think I'm only going to do that?" Wei Chihong's face seemed to be smiling, "The liar's eyes will drift before lying, and after thinking about what to lie, his eyes will become affirmative." This is how Hong Bingwei behaved when he first said that he didn't know the painting. I deliberately asked, didn't his father ever tell him, do you remember his reaction? ”

"Remember, he smiled unnaturally." Qiao Yan also expressed her opinion, "When a liar is faced with a question, he usually loses a little bit at first, and then takes advantage of the time to think quickly, come up with a lie that is not clever, and then respond with unusually firmness. Moreover, he will keep talking to himself, more and more, because when he is silent, he feels that others are still doubting him. If Hong Han hadn't opened the door and came in, he would definitely have continued to talk. ”

Yu Chihong nodded. "Heroes see the same thing."

Qiao Yan wanted to laugh, but when she saw that he was very serious, she held back again. "But it's useless to know that he's lying, you can't force him to say it."

Wei Chihong didn't respond, only said, "Let's go."

Today it was cool, the wind was strong, and there were few pedestrians on the road, so they all wore coats, put their hands in their coat pockets, and walked forward slowly. For a long time, he didn't speak, and she was silent. In this way, I walked all the way to the door of Qiao's mansion.

Qiao Yan stopped and asked, "Do you want to come in for coffee?" ”

Wei Chihong stopped, still looking at her, then shook his head and said softly: "No, it's too late, let's do it another day." ”

"Goodbye, then." Qiao Yan said.

Wei Chihong did not move. Qiao Yan was full of hope that he would propose a date, or the next time he came for coffee. She waited for him to speak, but he did not speak for a long time, and finally nodded to her, and whispered, "Okay, goodbye!" ”

Qiao Yan was disappointed in her heart, watching his tall back move away under the illumination of the street lamp, she exhaled inexplicably and rang the doorbell.

It was not Aunt A Xiu who came to open the door, but Qiao Ran.

"Hey, why are you alone?" Qiao Ran looked around.

"Gone." Qiao Yan was a little depressed.

Qiao Ran saw it. "Sister," she helped with the idea, "you also have to take the initiative at the right time, of course, not to let you take the initiative to confess, or to create some small situations, such as pretending to fall, and then falling into his arms or something." ”

"Don't have bad ideas, don't worry about my business. Besides, I don't have to be him, there are a lot of better men than him. Qiao Yan said this, but she was very sad in her heart, she hugged and kissed, but he didn't say anything at all.

Yu Chihong, ah Yu Chihong, what kind of status do I have in your mind?

"Sister, it's Christmas in a few days, and there are very exciting activities on Christmas Eve this year, let's call the big detective to go together." Qiao Ran is still enthusiastic about pulling the strings.

"People are Communists, atheists, and they are certainly not interested in church activities." Qiao Yan herself has no religious beliefs and is equally uninterested.

"I'm not talking about church activities." Qiao Ran immediately became excited, "I just read from the newspaper that the New Life Square is holding the HelloKitty Colorful Market, this year is HelloKitty's 40th birthday, there is a 3D world style theme exhibition area, HelloKitty giant Christmas tree, HelloKitty Happy Castle and the like, Christmas Eve There are also colorful concerts, various wonderful performances and five rounds of lucky draws."

Qiao Yan was a little moved by what she said, but she was not sure at all whether he would agree if she invited Yu Chihong to go with her. Besides, there may be emergencies at any time in their work, and even if they make an appointment, they may not be able to make the trip.

"Forget it." She sighed and said, "We're all busy, and we're probably going to have to work overtime on Christmas Eve." What's more, if he doesn't want to develop further with me, it's useless for me to take the initiative, so let's let it be. ”

Qiao Yan actually didn't expect that her estimated Christmas Eve overtime work would really come true. Two days before Christmas, a male deceased was found early in the morning in a small park in the city. The park is adjacent to the residential area, and residents found bodies during their morning exercises.

This is not an ordinary homicide, but the third deceased to appear in a serial homicide. Although the method of killing is different each time, the knife is inserted into the neck of the deceased, and the mark on the handle of the knife is like a smiling face, which is the case in all three cases, and it should be the same person.

Qiao Yan and Mo Yuqing both went to the scene of the crime. The victim's death posture was strange, he was lying on his knees on the ground, as if he was worshipping. A knife is stuck on the left side of the neck, with a smiley face carved into the hilt.

Wei Chihong also went to the scene in person, and Duan Zhiming reported that there were no traces of struggle on the ground, but there were tire marks left at the scene, and the murderer came by car.

There is also an important clue that the Arabic numeral "4" is written in blood on the ground next to the corpse. And Li Shuhua judged from the obvious strangulation marks on the deceased's neck that he was suffocated to death by being strangled with a rope. The knife was inserted after death. But no rope was found at the scene, and it should have been taken away by the murderer.

"With a knife engraved on the neck, could this be some kind of ritual?" Mo Yuqing speculated.

Qiao Yan shook her head. "Not really. If it is a ceremony, the knife handle is engraved, it should be a totem or something, and it will not be such a strange smiley face. ”

There was a large tree with lush foliage on the right side of the deceased, and the branches and leaves extended above the corpse, and after Yu Chihong's keen eyes inspected, he squatted down and picked up a branch from the ground, a slender branch, with several leaves attached to it, and one end of the branch had obvious traces of being broken. He took the branch and looked at it for a moment, then walked to the big tree and climbed it with agility.

Qiao Yan's eyes followed Yu Chihong, he was wearing a woolen coat of high-quality fabrics and high-end leather shoes, this outfit also had his own cold temperament, no matter how he looked at it, it was extremely incompatible with the behavior of climbing trees, but he did it so chic and free. She sighed in her heart that she could even climb a tree so handsomely.

"Hey, what are you doing!" Cao Chongshan, who was doing on-site identification, shouted at Wei Chihong.

Yu Chihong bent down, touched the tree pole with his hand, and then beckoned to Cao Chongshan. Cao Chongshan set up a ladder, climbed up, followed Yu Chihong's point, and saw obvious traces of peeling bark on the tree pole. "You guy, give me another job." Cao Chongshan muttered and called for the other appraisers to bring him a camera.

When Yu Chihong returned to the ground, he speculated that the murderer was ambushed on the trunk of the tree, and when the victim reached the bottom of the tree, he put a rope around his neck, and then jumped down in the opposite direction and strangled him to death, so there was no trace of struggle. "Investigate the neighborhood again, and first, devote ourselves to the work of determining the identity of the victim." He instructed Duan Zhiming.

The criminal police detachment set up a special task force to investigate this serial murder case.

In the evening, at the case seminar, the members of the task force reported on the current investigation: the first victim, the crime scene was located in a cemetery in the suburbs, with two lungs and liver, was stabbed by a sharp blade, and died of excessive blood loss. He also had a knife with a smiley face engraved on the hilt of his neck, which was the murder weapon that stabbed the victim to death; The second victim, the crime scene was located in an apartment building site in the city, the cause of death was acute poisoning caused by a large injection of stimulants, the composition of an instantaneous strong adhesive was detected from the eyelids of the deceased, and the same knife was inserted in his neck. In the first two crime scenes, the word "4" was also written in blood on the ground. No fingerprints were left on the murder weapon, and no other traces were found by the killer.

The identities of the three victims are unknown, and they can only be judged by their appearances as young men in their twenties. No witnesses were found near the three crime scenes, and no one knew the victims.

"In all three cases, the killers stabbed knives with the same pattern into the victims' necks after committing the murders, apparently using the exact same tactics as the unsolved serial killings four years ago." Li Haoxun, deputy director of the Public Security Bureau, who attended the meeting, explained that four years ago, there were three victims, all of whom were high school boys, and they were assassinated, poisoned, and strangled, and their modus operandi was different each time.

"It's a copycat." Lu Bin was the first to put forward his views.

Li Haoxun denied this view. "In the past four years, neither the knife nor the engraving has been made public, and the media has not reported it. This time too, the likelible of copycats is low. ”

"I think this case was the same person who did it four years ago." Fu Yiming's views are shared by most people.

"What is the opinion of the Special Investigation Team?" Li Haoxun wanted to hear what kind of conclusions could be drawn from the perspective of criminal psychology.
