"Qingcheng and I had doubted her before, a graduate student majoring in computer science, who has that ability. In addition, because of her own experience, she is eager to change the status quo under the fence, which leads to greedy for small profits in front of her, which is easy to be taken advantage of. Cheng Yijie analyzed, "The existence of hackers was initially determined when Qingcheng was hijacked by Jim into room 1208 of the hotel building where the community library is located. Although it is impossible to determine who Jim's accomplice is in the end, the suspicion of Chen Biting Jin and Xu Qiaoling still exists. Later, at the hotel in the Nanfeng Guqin Cultural Village, the hacker reappeared and helped Jim enter the room where Qingcheng and I were staying. And at that time, it was determined that Jim was among the guests of the hotel, and the hacker was probably one of the guests of the hotel. I'm 100% sure that your brother isn't Jim, and as for hackers, do you think he has that ability? ”

"How is it possible, he was a science student when he was studying, and he didn't know anything about computers." Chen Yufei thought it was funny.

"Therefore, I basically locked the object of suspicion on Xu Qiaoling later. Including the case of Mi Lan and his wife, she and your brother were also staying at the hotel on the night of the murder at the love hotel, and she should have been ordered by Jim to secretly assist Mi Lan in order to prevent her revenge plan from going haywire. Because your brother was bewitched by beauty, he innocently became her shield, and he was used several times without knowing it. Cheng Yijie said, "The fire in Sydney finally confirmed my judgment. It is clear that someone used the aging of wires to create a short circuit and caused a fire, and that person was a master and did not leave any traces. The purpose of creating a fire is to kill Xu Qiaoling to extinguish her mouth, she has no use value, and it will only be a disaster to keep it. ”

"My brother is sometimes as stupid as a donkey, and he thinks he is sorry, and he is complacent all day long." Chen Yufei hated that iron could not become steel, "Xu Qiaoling also did her own evil and couldn't live, but it was so pitiful that Xu Youran suffered from the pond fish and ended up in such a miserable end." ”

After a pause, she added: "Li Dong and his girlfriend have been threatened. It is said that one night, while the two were sleeping, a masked man suddenly broke into the room, pointed a gun at them, and threatened Li Dong to kill both of them and their families if they did not do what he asked. She firmly denied that she had been poisoned, and after examination, Li Dong died of potassium cyanide poisoning. Potassium cyanide is easily soluble in water, the aqueous solution is strongly alkaline, and it is quickly hydrolyzed, as long as it is poured into the meal. We have investigated, and Li Dong's girlfriend really has no source of poison. Of the six disposable cups used by Li Dong, four were detected with anesthetic ingredients. The thermos pot containing the soup did not detect the anesthetic, and the medicine was in the cup, as you had assumed earlier. ”

Cheng Yijie nodded. "As I expected, Li Dong was threatened, so he had to act as an internal response and drug his brother. The possibility that Li Dong's girlfriend was poisoned is indeed very small, I insist on my own judgment, the person who poisoned and the painting is the same person, Li Dong's girlfriend is not from the museum, it is impossible to be so familiar with the location of the space, and it is impossible to enter the office of the storage department. ”

"We looked at the surveillance footage of various parts of the museum and the performance site, and found no suspicious person. None of the people who watched the show last night left halfway. The first to leave were you, He Muxuan and me, and it was already early 9 o'clock at that time, and there was no time to commit the crime. Chen Yufei also said, "The insiders of the museum, who came to watch the performance last night, did not have time to commit the crime. Others who did not watch the performance, except for the security guards, as well as Mu Qingcheng who participated in the performance and Shi Qi, who was in charge of the props, did not even enter the square outside the museum. But will it be wearing an invisibility cloak again, we can't see it, do you want to see it for yourself? ”

"There's no need for that, I've carefully inspected all the places where there are surveillance cameras, except for the corridor on the second floor, the spatial structure of other places can't be completely invisible." Cheng Yijie seems to have a plan, "I analyzed the surveillance video in the corridor on the second floor, and came to the conclusion that from 7:45, someone came in through the window, passed through the corridor, and went all the way to the exhibition hall. Nearly 10 minutes later, I left the exhibition hall again, returned to the corridor the same way, and left through the window. In other words, the thieves came with the fakes, stayed in the exhibition hall for almost 10 minutes, quickly repacked the paintings, and left with the originals. It was nearly 8:05 a.m. when I got out of the window, so it took about 20 minutes in total. ”

The show started at 7:30 p.m., when Shi Qi was already on stage, he was in charge of the conversion of a long screen as a prop, and hid behind the screen until the end of the first half of the performance, and only temporarily returned backstage at nearly 8:30, as confirmed by the props crew. Mu Qingcheng only appeared in the second act, the time was exactly 7:45, and it was already early 8 o'clock at the end of the second act. Chen Yufei looked very distressed, "For Shi Qi and Mu Qingcheng, we have also conducted a more detailed investigation, but from the current situation, neither of them has time to commit crimes. I don't really have a clue who it will be. ”

"Shi Qi is hiding behind the screen and hasn't shown his face?" Cheng Yijie asked.

"We also thought about this question, and suspected that he had sneaked off the stage." "But he can't do it." Because the screen is on the left side of the stage, the actors go on the stage from the left side, and then go down from the right side, and leave directly through the actors' passage. After the performance, go back to the dressing room in the museum, and go back to the backstage on the left. There are always many actors waiting in the backstage on the left, and if you pass by there, someone will definitely see it, but no one has ever seen Shi Qi. And from the left to the right, you have to cross the stage, which is too conspicuous. We, as spectators, didn't notice anything unusual on stage. ”

Cheng Yijie thought for a long time, and couldn't come to a definite conclusion for the time being, the sky outside had already darkened, and he decided to find Mu Qingcheng at night to confirm whether there were any missing details, and then make further inferences.

When he received a call from Cheng Yijie, Mu Qingcheng was putting on makeup and was going to perform as usual tonight. Seeing the name beating on the screen, her heart missed a few beats, could it be that the private detective's matter was discovered by him and came to Xingshi to ask for the guilt?

"I'll pick you up after tonight's show." Cheng Yijie's voice swept past her heart, bringing a gentle sourness. made her feel a little warm in her disheartened mood.

"Are you going home?" She asked involuntarily, and her tone was unusually gentle.

Cheng Yijie paused slightly, Mu Qingcheng's gentle words made him unbearable to refuse, and finally let out a low "um".

After the second act of the evening, Mu Qingcheng completed the performance task and waited in the dressing room. In the process of waiting, one of her hearts was pounding, as if the long-dormant pool water was suddenly thrown stones, stirring up layers of waves. She even began to deny her previous suspicions about the relationship between Cheng Yijie and He Muxuan, thinking that if she misunderstood them, she would immediately ask her cousin to revoke the commission of the detective agency tomorrow.

Cheng Yijie arrived quickly, and after returning to the villa, Mu Qingcheng looked around, and a long-lost sense of intimacy came to his heart. She sat down on the sofa, and Cheng Yijie brewed a cup of Longjing tea for her, with its emerald green color, rich aroma, and pleasant emotions couldn't help but fill her chest. "Why are you free to pick me up today?" She asked, half-coquettishly.

"I'm worried that you're too tired to go back and forth, so I wronged myself and let you live in the dormitory of the song and dance theater temporarily." Cheng Yijie explained.

Mu Qingcheng looked at him, with such a sincere expression and such a sincere tone. She quietly lowered her eyelids, and quickly thought in her heart, women are such emotional animals, even if people tell lies, she takes them as the truth.

"When you performed on stage last night, Shi Qi was in charge of the screen on the stage, and he kept hiding behind the screen, right?" Cheng Yijie quickly changed the subject.

"Yes." Mu Qingcheng was a little strange, "Why did you ask about this again, the police have already asked me." ”

"Did anything unusual happen on stage when you were performing?" Cheng Yijie asked again, "This is very important, you recall it carefully, even the slightest detail should not be missed." ”

Mu Qingcheng rolled his eyes. "That's a little weird. It's just that when we change the queue, the position of the screen seems to be wrong. ”

"Was the screen on the left or right side of the stage?" Cheng Yijie asked.

"The screen was originally on the left side, and the position at that time was ......" On the stage, he felt that the screen was not in the right position for a short moment, Mu Qingcheng's memory was already blurred, and he thought about it for a while before saying, "It should be on the right side." ”

Cheng Yijie already knew it in his heart and didn't ask anything anymore. "It's not early, go take a shower and rest early."

Mu Qingcheng blushed for unknown reasons, jumped up from the sofa, and ran upstairs. When she went to the bedroom and opened the wardrobe, she saw the sexy pajamas embroidered with only three butterflies, and there seemed to be some kind of force that drove her to reach out and take the pajamas out and into the bathroom.

After taking a shower, she put on her pajamas and blushed in the mirror. In fact, it was not the first time she had worn such revealing clothes, at the beginning of the love hotel, the red gauze nightgown as thin as cicada wings was as thin as these three butterflies. But at that time, she was passively put on, and this time it was quite an active seduction. She didn't understand why she did this, maybe it was the long-suppressed urgency and desire in her heart, which suddenly erupted under the inducement of tonight's opportunity, and it was out of control.

She hesitated to wear the pajamas, but she was too embarrassed to go out to see him like this, so she added another bathrobe outside.
