Netherworld Investigator

"That kid in front of the pet shop is your son, right? Right?"

Qiao Kejun was immersed in his thoughts, and by the time he realized it, he had already driven the car into a road section that could not be reversed.He didn't care much and said: "He ran out to play by himself, this place is not far from home."

Wen Baifan squinted at him, and said tut: "You are a guardian with a big heart. Even if my cat runs out to play, I have to worry whether it will be bullied by dogs."

Qiao Kejun slowed down the speed of the car, and said lightly: "You get off at the intersection."

"Isn't that right, are you driving people out of the car?" Wen Baifan was shocked, "I said why are you so unacceptable to criticism!"

Qiao Kejun sighed: "You turn around and look for him, and I'll come back to pick you up after a circle."

Qiao Xin almost pressed her face against the glass wall of the pet shop, and met eyes with a silly little husky.

The erha wheezed its tongue and chased its tail around, looked up at the child, received the approval and encouragement in the child's eyes, then wheezed its tongue and turned around again, one person and one dog happily looked at each other with their eyes. play.

"Master Xin, what are you doing lying on the window?" Wen Baifan couldn't help but rub his hands a few times every time he saw the hair on Qiao Xin's head that was as soft as chicken feathers.

Qiao Xin looked up at him, then looked at the dog eagerly, and said, "I like this Alaska."

"What kind of eyes do you have?" Wen Baifan corrected him, "This is a husky."

Qiao Xin moved his nose forward and almost hit the glass: "I thought that one over there was the husky."

Wen Baifan took a look, "No, that's a border collie."

"I thought that was the collie over there."

"That one is also a sheepdog, but it's an ancient English sheepdog, the one in the Dulux paint advertisement." Wen Baifan smiled, "You like dogs so much?"

"Yeah." Qiao Xin replied sullenly, "But my father won't raise it for me."

"Come on, he's here to pick you up." Wen Baifan carried the child onto his arms, turned around, and saw a cool sports car parked at the opposite street corner.

"You said how could your little one be so heavy." Wen Baifan didn't expect that the child was much heavier than he imagined.

Qiao Xin grabbed Wen Baifan's neck and hugged it with his arms, "You said that the weight is so small that it is very heavy."

Wen Baifan had no choice but to grit his teeth to be brave, put his little butt in his arms and weighed up, and adjusted his posture. "I haven't asked you yet, why did you run out by yourself?"

Qiao Xin looked indifferent: "I'll go shopping."

Police officer Wen gave a serious education to the little citizen: "Do you know that this is dangerous?"

"Why is it dangerous?" Qiao Xin reached out to play with the little curly hair next to Wen Baifan's ear.

Wen Baifan thought for a while and said, "Because you are weak compared to adults, what if someone wants to bully you and no one will protect you?"

Qiao Xin challenged him: "Weakness and strength are not distinguished only by age and physical strength. A 30-year-old fool or a six-year-old genius, which one do you think is weaker?"

Wen Baifan narrowed his eyes: "Little genius, if you say that a 30-year-old idiot wants to beat you up now, what will you do?"

"Then I'll yell out my throat and wait for the uniformed uncle to come and save me." Qiao Xin pointed to a policeman who was patrolling not far away.

"Then what if Uncle Subdu wants to beat you up?" Wen Baifan tried to make him understand that there are many unexpected things lurking in this society.

Qiao Xin tilted his head and thought for a while, then replied solemnly: "If the wall confronts the egg, the broken egg must be the egg. It doesn't matter whether it is an old egg or a young egg."

"Hey, you kid can't even tell the breeds of dogs, but you know walls and eggs." Wen Baifan was speechless. Since we met, this kid would always spit out some remarks that were seriously inconsistent with his age, which made people very curious about Qiao's family. What is the state of education.

"There is a saying that there is specialization in art. Geniuses are born to think about big problems, but idiots..." Qiao Xin hung the whole body on Wen Baifan, and laughed loudly, "Idiots know how to bully children. Ah, I see I'm in Dad's car, put me down quickly, he won't let me hug you."

"Cross the river and tear down the bridge, you bastard." Wen Baifan put him down.

Qiao Xin didn't want to be led, so she reached out and grabbed the pocket of Wen Baifan's windbreaker.Suddenly he touched a flat horned thing, "Hey, what is this?"

"Paper boat, look, it can stand up when you arch it like this."

"Did you fold it?" Qiao Xin reached out and dialed it curiously. "My dad has one on his desk, exactly the same."

"It's different." Wen Baifan was full of complacency, and his tone quickly threw out a small tilde: "This is a gift from a pretty girl."

Qiao Xin looked up at him: "How small?"

Wen Baifan thought for a while and replied, "It's about your age."

"It's so small, why did she give it to you?"

Wen Baifan was overjoyed: "She likes me."

"Why does she like you? Have you played with her? Do you like her too?" Qiao Xin puffed up her cheeks, "If you can only afford one jelly, would you give it to me or her?"

Wen Baifan scratched his head, "I probably won't be so poor!"

"I mean what if." Qiao Xin persisted.

"If I'm so poor, what kind of jelly should I buy? It won't make you hungry." Wen Baifan put the paper boat in Qiao Xin's palm, "Well, I'll give it to you as a passing of love. OK?"

Qiao Xin raised her chin and nodded: "Okay, I accept."

After getting in the car, Qiao Xin grabbed the back of the driver's seat and handed the paper boat to Qiao Kejun: "Dad, here it is for you."

Qiao Kejun took it and asked, "What is this?"

"This is the transmission of love." Qiao Xin shook his little head triumphantly, and relayed to Qiao Kejun the token of love that has passed through many people, "Uncle Wen said, this is a gift for someone you like." Although it is always you and yours in front of Wen Baifan, but in front of Qiao Kejun, Qiao Xin will call him Uncle Wen obediently.

Uncle Wen, who was wearing his seat belt, suddenly paused, and said, "I declare in advance, I didn't sneak a peek on purpose, but I accidentally spotted it. There seems to be a piece of information in the pile of documents that Dr. Lu asked you to take away just now." Just a paper boat, who is this love that passed on to you?"

"Who is it?" Qiao Xin booed without knowing it.

Wen Baifan was amused by him, and suddenly remembered the frightened expression on the little doctor's face when he heard that Qiao Kejun had a child when he met Lu Kai at noon.

"Could it be that woman surnamed Xia?" Lu Kai said in shock.

After saying goodbye to the Qiao family and his son, Wen Baifan first went to the cat nursery, which was his aunt's house.

"Son, I'm back home." He pulled out the fluffy dumpling from the flowers.

The cat was in the midst of having fun, and it was a little dazed when it was suddenly lifted up. After thinking about it, it began to hug Papa Wen angrily.

Wen Baifan sniffled, and he smelled that familiar unknown fragrance again.The smell came from a plant that the cat had just played with. It had thick, green leaves, and pure white flowers that were somewhere between heart-shaped and halberd-shaped.

"Auntie, what kind of flower is this?"

"Ah, the white one? Calla lily."

The next day, Monday.

As soon as Wen Baifan got out of the elevator, he saw Fu Ruyun blocking the door of the office, and Wang Yu was blocking in front of Fu Ruyun.It was still about ten meters away, and he could already feel the tense atmosphere between the two of them.

Wen Baifan stood on tiptoe and approached slowly, as if he was afraid of scaring someone, he tentatively called out: "You guys..."

"You came back just in time!" Fu Ruyun and Wang Yu said in unison when they saw him.

"I need to find you, but your subordinates won't even let me in." Fu Ruyun complained.

"Can you count a little bit, anyone can go to the police station to get it." Wang Yu also complained.

Fu Ruyun crossed her arms and raised her chin: "Hey, what do you mean! When I used to work here, you hadn't graduated from college yet!"

Wang Yu leaned on the door frame with his right hand, looked at her with raised eyebrows, and mocked: "Before, you knew it was before. Now I am a policeman, but you are not."

He pointed at Wen Baifan, who was huddled aside like a quail, "Especially when the boss does nothing, I am even more obliged to protect the police's internal secrets and prevent irrelevant people from entering."

Wen Baifan bit the bullet and was between the two guys who were facing each other. He ignored Wang Yu's stare and took Fu Ruyun to the restaurant on the second floor.When Wen Baifan finally sat down with a drink, he felt that his iron head skills had already reached the level of obsession.

"According to Rongguang's last wish, he will donate blood after his death, and his body will be buried with his wife who died young. In addition, he will donate all his property to set up a medical award named after himself to reward those who have made outstanding achievements. Medical worker." Fu Ruyun's investigation revealed that Rong Guang entrusted a lawyer to make a will on the day of suicide, "As far as I know, Rong Guang's son has failed in business in recent years and has fallen into severe financial crisis. However, according to the will, He won't get a penny of inheritance."

Even the strictest father would probably not give money when his own flesh and blood needed it the most. Rongguang's will is really intriguing.

"I originally thought that the cause of Dr. Rongguang's death was worth investigating, but since you are sure that he was not a homicide, I would also trust your judgment." Fu Ruyun said, poking the straw into Wen Baifan's drink as a joke, the slightly bitter cocoa It blends with the mellow milk flavor on the tip of the tongue, and the taste is still good. No wonder he has always been in love with this stuff.

Wen Baifan tapped the back of her hand mercilessly, weighed in distress that half of the cocoa milk was missing, and couldn't help but chase her away: "Aren't you going to run the news, what are you doing here, go to work quickly. "

Fu Ruyun snorted and sat on the spot, refusing to move.

"You've been writing about Fu Jianbang recently, right?" Wen Baifan suddenly thought of something, and asked her, "Did you find any exclusive secrets, big reporter?"

"The side around him is protected like an iron bucket. Mosquitoes can't fly in, and there is no useful information to dig out." Fu Ruyun sighed weakly, "As expected of the big guy called 'Spider', the means Well, the people who work for him are very tight-lipped, and this reporter has no way to start."

"The person who works for him." Wen Baifan asked her suddenly: "Do you know that there is anything special in common between Fu Jianbang's previous secretaries?"

Fu Ruyun clicked on the information on the tablet, looked through it carefully, and said hesitantly for a long time: "I didn't find any particularly obvious communication, only one thing, Fang Qihang who committed suicide in between, and Zhou Wen who later succeeded him Tao, both of them are high-achieving students who graduated from Charter University. Although they are successors, Zhou Wentao is three years older than Fang Qihang and is his senior. However, they are from different departments. Fang Qihang is from the philosophy department, while Zhou Wentao is from the philosophy department. Department of Physics. Other than that, there is no connection between the two."

In the office, Qiao Kejun stared intently at the screen, which was showing the surveillance video of the corridor of the special inpatient department on the 6nd floor on the night of the 22th.

After the operation, Lin Li was wheeled into the ward at 06:30 pm, about five hours before she was found suffocated in her hospital bed.Lin Li was accompanied by two young nurses who left the ward around seven o'clock after completing the nursing procedures.During the period from 11:30 to [-]:[-], only three people entered the ward again. They were the attending doctor Xue Mingyuan, the head nurse Feng Baoyi, and the secretary Zhou Wentao.

Qiao Kejun recorded the time when these three people entered the ward respectively with a pen:

At 07:30, Xue Mingyuan made his first inspection and stayed in the ward for about six to seven minutes.

At 08:30, Xue Mingyuan made his second inspection and stayed for about three to four minutes.

At 09:30, Xue Mingyuan and the head nurse entered the ward together. Two minutes later, the head nurse exited the ward and took the down elevator to leave.Not long after, the elevator door opened again, and Zhou Wentao came out.

At 22:[-], Xue Mingyuan and Zhou Wentao left the [-]nd floor together.

At ten o'clock sharp, the lights in the hallway were turned off.

At 11:30, the lights in the corridor suddenly came on, which was the time when Rong Guang shot himself. At the same time, Feng Baoyi, who was in charge of the night patrol, took the elevator to the 22nd floor.

The chaotic picture on the screen continued to dance silently, and Qiao Kejun fell into deep thought while holding a cup.

If the possibility of the three people colluding to commit the crime is excluded, the most logical time for the crime to occur is from 11:30 to [-]:[-], but during this time, the camera shows that no one passes through the corridor, otherwise the sensor camera will capture people image is activated.

The windows in the ward were well closed. After Fang Qihang's fall from the building, the hospital specially added protective bars to the windows, so it seemed impossible for the murderer to climb in through the window.

Under these objective conditions, the only one who could sneak into the ward and murder Lin Li was probably only the ghost.

What is puzzling is not only the murderer's method of entering the ward, but also the calla lily that Feng Baoyi said was placed on Lin Li's chest.

Back then, Fang Qihang once had a short but daily conversation with Qiao Kejun. Xu realized that this cold and taciturn attending doctor would not give any real response to his words. People can only be extra relaxed in front of him.

He said that everyone around him knows that he has a soft spot for flowers like calla lilies.

Qiao Kejun blinked, and the fuzzy flesh and blood lingering in his mind quietly faded away, replaced by Fang Qihang's thin and delicate pale face.

I am afraid that this invisible perpetrator is the person who was closely related to the suicide incident back then, and the purpose of the other party's pretense is to remind the insider of what happened seven years ago.

Qiao Kejun frowned slightly, stretched out his index finger and pointed at the two white paper boats on the table. They were folded in exactly the same way, and the edges of the paper were all yellowed and old.

One of them was a thank-you gift given to him by Fang Qihang before his death, while the other was a relic that Qiao Kejun found under the patient's pillow after the accident happened.

After that, rumors and rumors hit Qiao Kejun overwhelmingly.After a lengthy review and inquiry, Qiao Kejun returned to the office tiredly, and casually stuffed the paper boat into a book that had nothing to do with work.Later, this book and other materials unrelated to the experiment were secretly preserved by Lu Kai, and returned to Qiao Kejun's hands until seven years later.

After recovering from the memories, the images on the screen continued to play.

The time in the lower right corner of the video shows that it is almost early morning. In the special inpatient department, two important patients died unexpectedly in a short period of time. The ominous white light shrouded everyone's faces.

Qiao Kejun's eyes swept over the several people with different expressions in front of Lin Li's ward, and the scene Feng Baoyi described yesterday suddenly broke into his mind...

"Dong dong." There was a knock on the door, and Qiao Kejun was startled. He accidentally knocked over the cup, and the water spread like a dendritic nerve, and wet the small paper boat on the table.

Wen Baifan pushed open the door and asked, "What are you busy with?"

Luo Fei raised his chin and compared to the screen, while his subordinates kept typing on the keyboard.

Wen Baifan took a closer look, and read the title word by word: "A report on the feasibility analysis of the classic reasoning bridge? What the hell are you doing?"

"This is the feasibility and probability of success of the various tricks in classic mystery novels summarized by the well-known blogger 'Shuai Jian', which is myself." Luo Fei happily introduced. He didn't even catch his breath after speaking.

"Handsome and cheap?" Wen Baifan gasped, "Shocked, I didn't expect you to be more accurate than GPS in positioning yourself."

"Please allow me to introduce myself, Shuai Jian is for a super handsome forensic officer." Luo Fei said brazenly. "Of course my advantage is not just being handsome, but as for my screen name, I have to keep a low profile."

Wen Baifan sneered: "I'm going to report you for doing private things during working hours."

"Careful and small report, you are jealous that I am an Internet celebrity." The moment Luo Fei said the words, he was also stunned by his own words, "God, I am too literary!"

Wen Baifan interrupted his narcissism, "Come on, writer, show me what you have written."

"I'm not bragging, this series has a high click-through rate on my blog. You see, the most reposted article is this article, which analyzes how the criminals in Yusuke Kishi's "Hammer of Glass" use scientific principles' Fooled the camera monitor."

Wen Baifan read the sentence excerpted by Luo Fei on the screen——

"The surveillance camera at the end of the corridor will be set to the warning video mode at night, that is, if the sensor detects an intruder, it will start recording. At the same time, the sensor lighting will also be turned on immediately to complement the brightness of the light. The two sensing systems work independently, and are designed to activate automatically as long as either party senses the infrared rays emitted by the body temperature of an intruder."

Luo Fei explained: "Surveillance cameras with sensors of this kind are becoming more and more common now, and many security-conscious companies, residences, banks and hospitals will choose this device."

Wen Baifan recalled that the Affiliated Hospital of Holy Mercy had installed a similar monitoring device. Judging from the scene environment, Lin Li's ward was an out-and-out secret room. He once suspected that the prisoner used an unknown new technology to commit crimes by remote control. .

Otherwise, could it still be a ghost killing people?

Wen Baifan's mouse button was pulled down, and continued to read the following text: "The human body emits an infrared wavelength of about 36.5°C, which is 6-14 μm. Installing a filter on the sensor that can only pass through this wavelength range can eliminate the biological radiation emitted by the human body. Thermal energy reacts selectively. After the sensor detects 6~14μm infrared rays, the lighting will be turned on. On the other hand, the same sensor is also installed in the video disc recorder that is set to start warning recording after nightfall. When infrared wavelengths in the same range are detected, the recording will also start. At the same time, the siren in the guard room will be triggered."

"Goodboy!" Wen Baifan's eyes lit up, and he rubbed Luo Fei's hair vigorously: "Tell me, how did the prisoner fool the alarm in the end?"

Luo Fei stretched out a finger mysteriously like a Zen master, "Al."

It has been nearly ten years since we first met, and this is the first time that Feng Baoyi appeared in front of Qiao Kejun without wearing a nurse uniform.Today she deliberately put on delicate nude makeup, and the brown eyeliner was slightly drawn downwards, making the originally sharp Danfeng eyes reveal a bit of tenderness.

But unexpectedly, this thoughtful attire was not as attractive as when she was wearing a white uniform.Maybe some people are naturally suitable for a certain profession, or maybe the other way around, the profession itself is like the knife and chisel in the hands of a sculptor, polishing a person's temperament little by little over the years.

Qiao Kejun stood up consciously, and graciously opened the chair behind her for her: "Sorry for taking the liberty to ask you out."

Feng Baoyi thanked her, shook her head and said with a smile, "It's okay, I happen to be on vacation today."

In front of Qiao Kejun, she will subconsciously restrain her strong aura, and she can vaguely see a bit of her charming and naive demeanor in the past.

But after all, seven years have passed, and Qiao Kejun is no longer the withdrawn and unkind doctor she used to be. Similarly, she is no longer the shy and introverted little nurse.After some unskilled but natural greetings, Feng Baoyi took the initiative to speak: "You came to me today, you probably have something to ask me."

"I do have something to ask you about the details of the incident on the night of the 6th." Qiao Kejun nodded, not noticing the disappointment that flashed in Feng Baoyi's eyes.

"I am not entrusted by anyone to investigate this case. I just want to know the truth of the matter. I hope you can look at the friendship you once had and don't hide anything from me. Next, if I make any mistakes, You can just interrupt me."

Feng Baoyi lowered her head and sighed inaudibly: "Okay."

"After discovering that the patient had stopped breathing, you judged based on experience that you had missed the last chance for rescue. In addition, things happened strangely, so you decided to inform the patient's family members of the news first."

"You are the most competent nurse, and you have always strictly followed the rules that you cannot use mobile phones in the sterile ward. Although there is a dedicated phone in the room, you usually use your work mobile phone to contact Secretary Zhou. In the panic, you still keep Following strict professional habits, you hurried out of the ward and took out your mobile phone only at the end of the corridor. While making a call, you kept staring at Lin Li’s closed door to ensure that you could get out of the room amidst the chaotic people coming and going. No one broke in."

"But when you returned to the ward again, you were surprised to find that Dr. Xue Mingyuan was already in the ward."

Feng Baoyi suddenly raised her head and looked at Qiao Kejun in disbelief. Those eyes that once fascinated her turned into a sharp scalpel, dissecting her memory layer by layer elegantly and precisely.

"He said he heard the noise and rushed there, but you knew in your heart that Xue Mingyuan was actually lying. During the whole process of you leaving the ward to make a phone call and then going back, you were sure that no one had entered that room."

"That is to say, Xue Mingyuan stayed in that ward from the beginning to the end."

"If I'm not mistaken, Lin Li was not murdered by some strange ghost, nor was she avenged and murdered by revenge, but as Fu Jianbang and the hospital announced to the public, she did die after the operation. "

Feng Baoyi was silent for a long time before slowly beginning to narrate, "At 09:30 that night, Dr. Xue and I went to the ward together. At that time, Mrs. Fu's condition suddenly deteriorated, and Dr. Xue ordered me to go downstairs to prepare a medicine. ...But not long after, he called the pharmacy with a dedicated phone and informed me that Mrs. Fu's condition had stabilized, and asked me to go to the duty room to rest first, and just go to the normal inspection at night."

She collected herself, and said in an uncertain tone, "But when I walked out of the ward, I clearly heard the electrocardiogram alarm coming from the door..."
