The villain is trapped in the system and begs me to let him out [Moriarty who worries about the coun

As soon as Du Ruoying and William Moriarty came in, Police Officer Lu hurried up to greet him: "I didn't expect that we would meet again, Professor William. In fact, we are just looking for you today on a routine basis, and I hope you Don't be surprised--by the way, you really treat each other with admiration after three days of separation, and after only one day of seeing you, you have already become a popular person on the hot search..." As if afraid of being heard by Police Officer Yuan, the next sentence He deliberately lowered his voice, "Hey, we're already acquainted once and twice, why don't you send me an autograph later?"

Seeing that the other party finally closed the conversation, William, who had been listening quietly, showed a polite smile: "Sorry, Ibegyourpardon?"

Oh, I forgot that this foreign teacher can't understand Chinese...

Officer Lu turned heartbroken and looked at Du Ruoxian: "Brother, why don't you go up?"

Du Ruoxian nodded silently, stepped forward and explained the general situation to William in English, and then began to ask questions.

"The victim's name is Luo Yu, who was studying software engineering at Bei Yu University. Do you know him?"

Looking at the photo Du Ruoxian handed over, William shook his head: "I don't know."

"So, since the incident, have you had close contact with the victim and the crime scene?"

"I don't think so."

"Well... What were you doing from three to five in the morning this morning?"

"sleeping."

"Anyone testify?"

Hearing this question, William looked up at Du Ruoying for a moment, then smiled and said, "No."

Seeing that William didn't mention herself, Du Ruoying couldn't help showing a puzzled expression.Although it would be useless even if she confessed, after all, sleeping pills made her sleep deeply, so in fact, it could not provide him with a reliable alibi.But why would he choose not to speak out?Is it out of kindness?Don't want to let my brother misunderstand?

Does this guy actually have such a thing as "good intentions"?

"Is there no alibi..." Du Ruoxian pondered, "Then I may have to trouble you to go to the police station with us. We found a blond hair in the poisoned food, and we need your cooperation to do a DNA test."

"No problem, but—can I bring classmate Xiaoying?"

"can."

Officer Lu, who was also standing on the sidelines, raised his elbow and lightly poked her arm, and asked quietly, "What's the matter with you two? I think you've been sticking together today. Are you okay?"

"...How is that possible." Du Ruoying said helplessly, "That guy just needs someone to help him adapt to life in a foreign country."

"Oh, it just so happens that you owe him another life-saving grace, right?" Police Officer Lu said clearly, "I didn't expect you to have a bit of a conscience. I was the one who misjudged you last time."

"...?!!"

The group returned to the police station by car and collected blood samples from William. Then Du Ruoxian was in charge of continuing the questioning, and Officer Lu was in charge of searching for clues in the surveillance data.Officer Yuan and Du Ruoying stood outside the interrogation room, looking inside through the one-way see-through glass.

"It's useless, it's just a waste of time. Even if William lost his hair, he certainly didn't kill him." She sighed softly, "He had a class last night, maybe he was picked up by the murderer during the class hair and put on the scene for planting purposes."

"Oh, you're so sure that he's not the murderer this time?" Police Officer Yuan smiled, "Didn't you wish for someone to get involved last time?"

Du Ruoying, who was suddenly stunned, had no choice but to curl her lips.She thought unhappily: It was his fault last time, and I was right... But this time is different.He was the criminal genius William James Moriarty!Even if he wanted to kill someone, he couldn't kill him so simply and straightforwardly.

And judging from the scene, the murderer should be a guy who is familiar with the victim. If the hair clues are also confirmed, it can be further deduced that the murderer has seen William, maybe he is a classmate of Jianyuan... …

However, she still felt a little concerned about William going out in the middle of the night without telling her.

Could it be that he is not entirely innocent?

"Some interesting things were found in the surveillance." Officer Lu walked into the interrogation room and handed Du Ruoxian a stack of A4-sized black and white photocopies.

"Did you take any pictures of the crime scene?"

"Not really. The camera in that direction just broke down a few days ago." Police Officer Lu said, "The interesting thing I'm talking about refers to Professor William."

Du Ruoxian flipped through the documents, and then asked William, "According to the surveillance data, you went out at one o'clock in the morning."

"Well, I went out, but I'll be back soon." William said, his eyes fell on the document in his hand.

Monitor...?It seems to be a new technology that can record whereabouts.

William's answer was quickly confirmed in the surveillance data-he went out for a short time, no more than 10 minutes, and then went straight back to the apartment.

But he looked very strange when he came back.It can be vaguely seen from the monitoring screen that his white shirt is clinging to his skin, becoming slightly transparent, his hair has lost its fluff, and water drips from his temples from time to time.Wherever he walked, he also left a string of wet footprints.

"What's going on here?" Du Ruoxian asked, "Did you fall into the water?"

"Well, because I couldn't sleep, I went out for a walk in Qinxue Lake, but I didn't expect my feet to slip—so I went back soon." William said, "After all, the summer night in Beiyu City is still very cold."

Du Ruoxian showed a suspicious expression, then raised his head and said to Police Officer Lu: "Please bring me a notebook with all surveillance copies, and I will confirm a few other contents."

Officer Lu nodded, and quickly brought back a computer: "Well... don't say I didn't warn you in advance, there may be something in it that will make you angry."

A trace of curiosity flashed across Du Ruoxian's face, and he clicked on the video.He quickly checked the monitoring around the Qinxue Lake, and found that the location where William fell into the water was one of the blind spots of the monitoring.Then, he began to check the surveillance in the teacher's apartment.The screen was double-speeded to ten o'clock last night, when William had just finished class and returned to the teacher's apartment.Next to him was a person who returned with him——Du Ruoying.

Double the speed again to seven o'clock this morning, and you can see Du Ruoying and William appearing side by side in the screen again, and the two walked out of the apartment together.

Du Ruoxian's eyes slowly moved from the computer screen to William, and he tried to keep his tone as calm as possible: "You...are you really alone last night?"

"Ah, bad. It seems that you discovered it," William shrugged with a smile, "However, I hope you can listen to my explanation about classmate Xiaoying."

"Well, I'm listening."

"Actually, your sister and I slept in two separate rooms. I swear, I didn't do anything to her." William said unhurriedly, glanced at Officer Lu, and saw that the other party's face was full of suspicion look.In contrast, Du Ruoxian didn't seem emotional.So he continued, "The reason why I didn't mention her earlier is because I saw that she really slept deeply at night, and I'm afraid it can't be used as my alibi—" These words were like an invisible thorn, stabbing Du Ruoxian frowned, and the veins on the back of his hands twitched slightly. "Of course there is another reason—we don't want everyone to misunderstand. Anyway, it's something that doesn't need to be said. For her, it's definitely best not to mention it."

Outside the interrogation room, Du Ruoying was already sweating profusely.

Hey, hey, the more you explain, the easier it is for people to misunderstand!What do you mean by "I think she really sleeps very deeply at night", what do you mean by "It would be best for her not to mention it"?On purpose, definitely on purpose? ! !

This is really jumping into the Yellow River and I can't wash it off...

"It's not good, Captain Yuan! Something happened to Bei Yu University again!" A panicked young policewoman ran to Police Officer Yuan and reported.

"What happened?" Officer Yuan asked sideways.

"Another student was poisoned to death while having lunch in the No. [-] cafeteria." The police officer replied, "Just received a call from the school, saying that he was poisoned on the spot."

"What?!" His face darkened, "Well, first, you arrange some police officers on duty in the third canteen to go to the fourth canteen to maintain the scene, and we will go there immediately."

"Huh? Here again?" Police Officer Lu who had just come out of the interrogation room suddenly cried, "It's fine if I don't have breakfast, can't I not even have lunch?!"

Du Ruoxian also came out of the interrogation room: "I'll go too."

"Have you finished the interrogation?" Officer Yuan asked.

"The interrogation is over... Besides, he barely has an alibi. After all, the surveillance in the teacher's apartment can prove that he didn't have time to go to the third canteen to commit crimes... and he really didn't have a motive..." Du Ruoxian said, looking at Du Ruoxian Ying glanced at her, and she was so scared that she quickly looked away.

Police Officer Lu also followed his gaze to look at her: "Hey, this is really a downturn in the world, morality is degraded, and people's hearts are not old..."

Du Ruoying covered her eyes in embarrassment, and sighed secretly.

"Ah, I really wish there was a crack in the ground that I could crawl into."

"It's just right, let's take them back on the way." Officer Yuan said, and he called everyone to get into the police car together.

Back in the No. [-] cafeteria, several students reported what they saw to the police as witnesses.This time the victim was Gu Yue.She didn't look different when she was cooking and picking up the tableware, and she was alone when she returned to the table to eat. It stands to reason that it is impossible to be poisoned, but unfortunately it happened.

"The wounds on my body... are all old wounds." Du Ruoxian inspected, "The cause of death was still organophosphorus pesticide poisoning, and the end of the chopsticks was also coated with poison. It seems likely that the same murderer did it—but Why are the chopsticks in the cafeteria poisoned..."

"Chopsticks... that's impossible!" the person in charge of the canteen exclaimed in surprise, "Since the incident happened this morning, the higher-ups have started to strictly control the safety of the canteen. These chopsticks were put on the table after we disinfected them uniformly after ten o'clock, and The chopsticks are always placed where people come and go, and the cooking staff can see it at any time, so there is no chance of poisoning."

"It's really strange." Du Ruoxian thought about it, "And the chopsticks are all close together... If there is really a pair of poison, then the other chopsticks will hardly not be affected..."

"If the poison was smeared on the chopsticks in the cafeteria, could it be said that this time it was an indiscriminate killing?" Officer Lu asked.

"Indiscriminate killing? It's very unlikely..." Du Ruoxian said.

"Captain Yuan, another blond hair was found in the victim's meal." A technician who was packing the evidence suddenly stopped what he was doing and reported.

At the same time, the test report from the appraisal department also came in, confirming that the blond hair found in the previous case was indeed consistent with William's DNA.

What is going on in this case, why did the murderer frame a foreigner who had no motive?Du Ruoxian gradually felt a splitting headache.

Afterwards, the police went to the monitoring room to retrieve the monitoring screen of the time period when the incident occurred. From the screen, it can be seen that Gu Yue had indeed taken a pair of chopsticks from the public chopstick holder, and was sitting alone in a group of four from the beginning to the end. on the table.Although I went to the washbasin at the door to wash my hands before starting, there was still no chance for the murderer to drop bags or poison.

But this is by no means an indiscriminate murder, Du Ruoxian couldn't be more clear in his heart - because the two victims knew each other, it couldn't be a coincidence.

In the previous case, there were four suspects except William:

Li Muzheng, male, majoring in software engineering, was a classmate of the victim Luo Yu, who seemed to be close, but in fact often had disputes secretly.This guy has become suspicious and hesitating since the incident.In the morning, he even wanted to break through the barrier and escape from the scene.This person is also Gu Yue's boyfriend, but he has been at odds with Gu Yue recently.

Luo Xiaoxue, female, majored in architecture, Gu Yue's best friend, although she has become estranged a lot recently.Li Muzheng said that she often blackmailed Luo Ye secretly, so Du Ruoxian thought that she should have no motive to kill.However, unexpectedly, during the questioning in the morning, she seemed a little too happy about Luo Yu's death.

Chu Tianxing, male, majored in software engineering, Gu Yue's ex-boyfriend.There was a fight with Luo Yu some time ago.After learning the news of Luo Yu's death, she still had a lingering anger towards him.

Finally, there is the dead Gu Yue in front of her. She usually hates Luo Yu's entanglement with her in every possible way...

These people are familiar with each other, have intricate relationships, and none of them have reliable alibi.Two acquaintances, Luo Yu and Gu Yue, were killed in one day, if it was a coincidence, the probability would be too small.

The suspicious case in the morning caused the school to strictly restrict entry and exit, and the current search work has temporarily found no sign of anyone possessing poison, which also makes him feel a little concerned.

What concerned him most was why the murderer chose to frame William repeatedly.If the above-mentioned suspects are planted, at least in terms of motivation, it will be easier for the police to believe.

Too much to say...

On the other side, Du Ruoying, who learned that the blond hair appeared at the scene of the crime again, couldn't help but look at him speechlessly: "Are you a cat, why do you keep losing your hair?"

"It's not my fault, is it?" William sneered and spread his hands, "Speaking of which, this murderer is really naughty, what should I do with him?"

As the saying goes: When William smiles, life and death are unpredictable.

Seeing the corner of his mouth raised, she suddenly felt her spine explode: "Hey, you...you aren't thinking about anything bad, are you?"

"Huh? What's wrong?" he asked kindly.

"Such as finding out the murderer and killing him secretly?" She scratched her head uneasily.

"That's a good proposition," he said.

"What..." Seeing that he didn't make any excuses, she couldn't help but feel a little shocked, "I won't let you do this!"

"Is classmate Xiaoying planning to protect him?" He joked, "Is there any value in protecting a guy who killed classmate Gu Yue?"

"It's not protection, it's to make him get the right punishment." She corrected, "Anyway, as long as you can find the murderer one step ahead of you and hand him over to the police, you can't do anything."

"Oh?" William narrowed his eyes coldly, "Are you challenging me?"

"Whatever you say."

"Then I really feel sorry for you from the bottom of my heart," he smiled, and then said calmly, "After all, from a mathematical point of view—your winning rate is zero."
