A few minutes ago, the alarm ringed, and the nurses entered the ward and found that the monitor showed that Frank had no vital signs, so they immediately started to rescue him. Adrenaline, defibrillation and other methods were used, and Frank had no vital signs. The doctor arrived in one minute, looked at his pupils and rescued him for a few minutes, and declared Frank dead.

The doctor told Baker very surely: Even if Frank was really infected with ricin, he would not be able to die like this.

When investigating and monitoring, Liang Xi and Baker knew that it was not an accident. A hacker broke into the monitoring system and disconnected the system's storage. The security guards in the monitoring room could still see the pictures, but these pictures would not be saved on disk. The system was still in a state of refusal to write when they checked the monitoring, and the monitoring of the entire hospital was the same.

Fiona's technical support informed Liang Bei: This method is very ordinary, and the write permission is turned off with administrator permissions. Fiona's own computer demonstration is probably right-clicking on a file, then clicking on the attributes, chewing on read-only, and clicking OK. Others can only view this file, but cannot be modified.

Fiona said that the same effect can be achieved through the network, physical wiring, or even directly operating on the hospital keyboard, because the technical content is too low, Fiona cannot know any information about the hacker. If a person is beaten to death by a stick, there are many suspects. If a person is killed by a nuclear bomb, there are only a few suspects.

The forensic doctor has reached a preliminary conclusion: cyanide poisoning.

This completely confused Liang Xi. He first cut his fingers, injected ricin, and then used cyanide. Why?

I can’t understand the physical evidence analysis. My fingers were placed in a medical insulator and the wound was treated. According to the doctor, I had the ability and certainty to pick up my fingers within 6 hours. From this point of view, the kidnappers did not want to kill Frank, and even did not intend to mess with him. Well, I was not that flexible when picking him up, so I could be considered a mess.

Compared to ricin, this is nothing. Poisoned people will die irreversibly and die in pain. Since we have to do this, why do we still have to play with our fingers? Medical insulators are high-end goods and professional tools for transporting transplant organs. Does it cost money? Stealing also requires labor costs.

The strangest thing is that Frank was given a shot of cyanide when he was bound to die.

Liang Xi grabbed Baker and said to himself: "The first question is also a reminder: Frank got angry when he woke up because he found that his finger was gone. Reverse: He didn't know the process and result of his finger being cut off. Let's expand it. His finger was cut off at about 8:30, and Frank called 123 through a voice call at 9:00. The phone was Frank. Can we understand this way? The kidnapper gave Frank a chance to ask for help, and he woke up with anesthesia. Frank saw his phone, so he called the phone for help through voice."

Liang Xi did not wait for Baker to speak, and said, "The first question: Frank has not felt pain in his fingers and is not very clear. Normal people should call the police. Even if the first call is called to a friend, the second call must be called, right? No. But it is certain that Frank's hand is tied back and may cause pain, but the reason for the effect of the medicine will not be too painful. In addition, Frank's mouth is not blocked."

Baker asked: "Will it be that they were stuffed into the trunk after making the phone and sealed it?"

Liang Xi said: "This possibility is not ruled out. Let's ignore this for now. We should care about the owner of the 123 number, and we kept talking for about 40 seconds. Frank shouted: Shuai Xia, called 123, and the phone received a voice command and connected 123. It means that the 123 number is stored in his mobile phone, which means that he knows the owner of the 123 number. Is there any problem with this understanding?"

Baker nodded: "No."

Liang Xi said: "The second question: Why didn't 123 call the police? Didn't rescue Frank? Perhaps 123 doesn't know the location, so he should also call the police. Even if 123 is not convenient to call the police, Frank will be asked to call the police by himself. Then why didn't there be a call?"

Baker pondered: Where did I know?

Liang Xi said: "The logical explanation is: 123 came to rescue Frank, and Frank was found in the trunk through positioning or other methods. Two possibilities, one might not find Frank, and the other might not find Frank. Should Frank be called the police for help without finding Frank? We analyzed 123 and found Frank with a high probability. Several more questions appeared. The first question: Why did 123 not save Frank? The second question: 123 brought ricin to see Frank?"

Baker said: "Ordinary people do not have ricin, and normal gangsters will not use ricin unless it is an intelligence agency."

Liang Xi said: "123 received the call at 9 o'clock. He had enough time to be rich. Maybe he planned to rescue Frank, but he went back to get the ricin. Two groups of people, two groups of different people."

Liang Xi opened his mind: "Three groups, three groups. One group taught Frank a lesson. One group wanted to kill Frank slowly, but the other group didn't want Frank to die too slowly."

Liang Xi said excitedly: "This explains all the evidence contradictions. The second group of people 123 came to the scene and saw that the guy's fingers were gone... They threw their fingers into the river, and they sealed Frank. Why do you need ricin? Is there any explanation? They wanted to delay Frank's death and even leave plenty of last words."

Liang Xi was about to speak, and Baker looked at Liang Xi's raised index finger, and twitched up and down with Liang Xi's head: buddy, hurry up, work harder, you'll have it right away.

Liang Xi grabbed Baker's arm with one hand: "Who did that just now?"

"Frank? Doctor?" Baker was not sure: "The poison caused by physical evidence?"

Liang Xi: "No, that fat man called..."

"House."

"Yes, House, go and check if there is a dying person in the hospital department. He has three children." Liang Xishen exhaled his breath. The ricin made Liang Xi think of the intelligence personnel at the first time. He happened to meet House again. Frank was American, so it was easy to get in touch. That's right, the second group of people wanted to frame the third group, and the third group immediately took action after receiving the news to avoid being framed. Who is the first group of people in TM?

...

Baker brought back Liang Xi's unexpected answer. There was indeed an old man who had about a month left and he had three children. The old man lived in ICU, and Baker could not get consent to talk to him. Asked the medical staff and learned that House had a few minutes of conversation with the old man in ICU through an external phone call.

Damn! House didn't lie. He really came to the hospital because of his work. However, Liang Xi knew that House was an old fox. Think about it calmly. If House dared to say that, he would not be afraid of being investigated. His idea should be correct. The important thing now is to find out Frank's identity and background.

In the afternoon, Baker obtained some of Frank's information, which was obtained by the department's boss through a friend of the American criminal police. The specific information will be transmitted to the National Penalty 24 hours later with official documents.

Frank, serving at the age of 22, retired at the age of 27, is single, and is an electrician. He is not affiliated with any company or unit, he is a casual worker, similar to a deliveryman, with good income, do what he wants, and travel if he doesn't want to do it. Frank travels abroad half of the year, checks his booking hotels, and is a relatively cheap hotel, and only chooses economy class for the plane. Currently, his US dollar account balance in the United States is 17,000 US dollars, and the euro balance is 4,000 euros. In addition, there are pounds worth hundreds to thousands of pounds, Indonesian rupiah, Vietnamese dong, Thailand, Colombia, Argentina, Chile and other currencies.

This guy has been to many countries and has traveled across five continents. Judging from his passport and customs information, he only went to South Africa and went twice. This is his fifth time in London. He stayed at Sanfan Hotel the first few times, and the price of Sanfan Hotel is relatively cheap.

What's strange is that Frank has been to so many countries and should love traveling, but Frank has not left any photos on the personal media that must be dead. In fact, Frank only applied for an account that must be dead, and even has not operated it. This is somewhat out of place with tourists. Some people are afraid that others will not know when they go to the entrance of the village, and the photos are posted all over the sky in their circle of friends.

These information is completely unhelpful. Now we need to solve the case as soon as possible. There is a more aggressive way, that is, through the mobile phone left by Frank, contact 123 in the mobile phone address book. Another way is to take a chance.

Liang Xi said to Baker: "Let's go to Sanfan Hotel."

...

Frank stayed in Room 507 of Sanfan Hotel. The room was very small, with a single bed mixed with the living room. There were no other extra rooms except the bathroom that was integrated with washing and shower. The physical evidence personnel had searched the room and found no blood. They extracted fingerprints that could be extracted, and took Frank's personal belongings after taking the photo.

Liang Xi sat on the sofa in the guest room of 507, looking at Frank's personal belongings list on Baker's mobile phone. Frank's personal belongings are very simple, two sets of laundry pants and a down jacket to deal with the possible cold wave. In addition to the ID and cash, the remaining personal belongings are only an electric shaver.

"Very minimalist life!" This is a life attitude that has emerged in recent years. Don't want anything that is useless or useless.

Liang Xi looked at Frank's personal belongings and said, "There is one missing."

Baker asked: "What?"

"Charger." Liang Xi said: "Even if it is minimalist, you always have to bring a mobile phone charger, right?"

Baker: "It is possible that he brought it with him and lost it during the kidnapping."

Liang Xi's phone rang, and it was Hannah who called: "Hello."

Hannah: "Have you read the information?"

"Look."

Hannah: "What do you think?"

Liang Xi said: "I'm sorry, I have no constructive comments for the time being."

Hannah: "Okay, contact me again."

"Goodbye." Liang Xi hung up the phone and asked the room waiter waiting at the door: "Is this resident often going out?"

The waiter replied: "There are fewer, and most of the people are there in the morning. He cleaned the room at 10 o'clock twice, and he just got up and washed it."

Liang Xi asked: "Does he have a laptop or a tablet?"

The waiter nodded: "Yes."

Baker was curious about looking at Liang Xi, how did you know?

Liang Xi pointed to the marks left by the carpet by the table, which is a trace left by long-term squeezing of the chair legs. Therefore, Liang Xi speculated that Frank spent most of his time in the room and sat on a chair most of his time. To be honest, if he was playing games or socializing, or for other reasons, many people would choose to lie on the bed instead of sitting on the chair straight. The only reason for sitting on the chair for a long time is work. Even traditional writers use computers to work, so Liang Xi speculated that Frank should have a working computer.

Liang Xi asked: "Is there any surveillance in the corridor?"

The waiter replied: "No, there is only monitoring in the hotel lobby, staircase and elevator." The corridor of Sanfan Hotel is not a zigzag, but an irregular zigzag. If corridor monitoring is to be installed, at least five to six monitoring monitors must be installed on one floor.

"Let's go and check whether Frank brought a computer with him the last time he left the hotel." Liang Xi added: "If you bring a computer, you may also put the charger inside.

The answer was to bring it. Frank left the hotel with his computer bag at around 8 o'clock the day before yesterday and got into a taxi outside the hotel. Baker found the taxi through the surveillance outside the hotel. The taxi driver recalled that Frank went to Street 3 of Windsor Community.

Windsor Community is Jinling Community, not far from the city center. It is the most popular community for middle and senior management of large enterprises with good income. Compared with ordinary communities, the community culture of Windsor Community is relatively weak. Everyone lives their own lives, is not keen on community activities, and does not want others to disturb them.

Baker took people to Windsor community to track down Frank, leaving a detective to accompany Liang Xi in the 507 hotel room. Liang Xi did not want to do the police work, so he didn't know how many people he would visit or how many cameras he looked at when he arrived in Windsor community. Maybe there was no result yet. Liang Xi asked the detective to investigate something, and found out from the surveillance camera whether Frank would carry his computer with him every time he left the hotel or left the room to have dinner in the restaurant.

After getting the affirmative answer, Liang Xi contacted Fiona: "Is there anyone in your circle named Frank?"

Fiona: "You are very amateur. There is only code name in the circle, but no name. For example, my name is Dwarf, and I have some popularity in the European circle." Many people think Dwarf is a fat man.

Liang Xi asked: "Can't find it?"

Fiona: "You can help you check the registered hacker information. Most of these people have been arrested for attacking official websites."

Liang Xi said: "I want American ones."

Fiona said: "There is no problem, but you can only find ordinary hackers. There is a special system for high-risk hackers. Tell me the full name."

Liang Xi reported Frank's full name, and Fiona quickly replied: "There is no such person."

"Okay." Liang Xi could only hang up the phone.

The police investigated who kidnapped Frank, who injected ricin, and who injected Frank with cyanide. Liang Xi was more interested in Frank's identity. This person must have problems, which led to people attacking him in a series of ways.

According to Liang Xi's understanding, a man who spends most of his time dealing with laptops in a hotel room can first rule out that he is a game enthusiast. A real game enthusiast may either play host or desktop. It may be a programmer, but Frank's identity is an electrician. Assuming Frank wants to cover up his identity, he should also be a programmer in the United States. After excluding several possibilities, Liang Xi suspected that Frank was a hacker.

Contacting the hospital again, I happened to meet House today. Liang Xi had reason to suspect that Frank was a hacker who worked for Ca. This explained why he often traveled abroad. The most important thing is minimalist life. The personal belongings are simple and the room is simple. There is an advantage of minimalist life. You can hide a bug that you have no place to hide.

"Please check it out. How many people check out after 9 o'clock last night to 7 o'clock this morning?" Thinking on the other hand, Frank must be noticed by many people. To kidnap Frank, you must have some understanding of Frank. Frank is in the guest room most of the time, how can he understand him? Direct surveillance should be a better method.

The front desk waiter replied: "Police officer, no one checked out."

"Oh? Thank you." Liang Xi took out his cell phone and opened the photo of House: "Have you seen this person?"

"No." The two staff members shook their heads together.
Chapter completed!
