When the doorbell rang for the fifth time, Liang Xi reluctantly hung up the bookmark, closed the book, put on his slippers and went to the front door. Now that there was no need for a peephole, the monitor next to the door told Liang Xi that the person who rang the doorbell was a man in his forties. From then on.

Judging from the men's attire, it should be

He is a homeless person. The welfare protection in the UK is relatively complete. Most homeless people have their own reasons. But this person is skinny, his clothes are ragged, his hair is dirty and knotted, and he doesn’t care about his appearance at all. He is most likely a homeless person.

Addict.

Liang Xi walked back and took out a few banknotes from his pocket. Such people usually squander all their security benefits and treat every day as their last. Although he doesn't like these people, Liang Xi is not stingy either.

Provide them with survival help. In addition, it can be seen from the surveillance that this person is timid, has empty hands, and has no hidden weapons...

Liang Xi opened the door, and the man took a step back, holding on to the handrail, and said awkwardly but politely: "Hello, sir."

"Hello."

The man opened his smelly tattered jacket and took out a snow-white letter: "Someone asked me to give this letter to you."

Liang Xi did not accept the envelope and asked: "When?"

The man replied: "Just now, ten minutes or more. I was queuing up for bread outside a street, and a gentleman wearing a top hat and a mask asked me if I wanted to make some money."

It happened shortly after he arrived at the detective agency. Liang Ximing took the letter and handed the 60 pounds in his hand to the man. The man hesitated, then took the banknote and thanked Liang Ximing.

"It's okay, please be kind to yourself. Goodbye." Liang Xi watched the man go downstairs and closed the door. Even facing such a person, Liang Xi didn't want to lose his courtesy. Maybe this was hypocrisy, because in his heart Liang Xi looked down on him.

.

Liang Xi first checked the letter under the light, mainly to see if there was anything in the letter. If it was powdery, he had to call the police. But the letter was just a letter. Liang Xi opened the letter and found nothing inside except a map of the Greater London area.

, the Greater London map includes not only the urban area, but also the suburbs within ten kilometers of the suburbs of London.

What does this mean? Liang Xi observed the paper map and found that 95% of the map was new. The reason why he said this is because apart from the creases, there were not very obvious human traces on the map. This is a very ordinary administrative map.

Every street, every small park, every alley is on it. Because of their different importance, they use different shades of fonts to mark them. The dense text combined with the dense buildings makes people feel dizzy at a glance.

The only hint of information is that there are several advertising paper-cut numbers at the top of the map: 27, 13, 35. They are not latitude and longitude, nor street codes. What are they? Many people will throw them aside after receiving similar things and studying them for a while.

, by the way, crazy. The detective's intuition told Liang Xi that there was something hidden in this map. Reasoning one: A homeless man who doesn't care about his own image goes to receive free bread, which means he is very hungry. Reasoning two: This kind of weather arrangement

There won't be many people in the queue, and there is only one reason for giving up, and that is because the money is more. Reasoning 3: Although this homeless man is dirty and smelly, he has a better personality among homeless people. Most of them are bankrupt and his wife and children are separated.

, a person who is mentally decadent and gives up on himself. Did the other party find such a tramp by chance, or did he choose such a tramp? Reasoning 4: The time of sending the letter. According to the calculation, after the other party sees that he has entered the detective agency, he will then look for a suitable messenger.

This man was not very rich, but he had some knowledge of criminal investigation. Liang Xi looked at the envelope and the map in backlight and forward light, and found only the grease left when the homeless man handled the envelope. Liang Xi took out a can of magnetic powder, which was carbon powder and iron powder.

The mixture is a professional tool for extracting fingerprints. Although I don’t know if it has a shelf life or how long it has been stored, Liang Xi believes it can still be used. After using it, Liang Xi confirmed that there were no fingerprints on the envelope or map except for the homeless man.

.

The back of the map was blank. Liang Xi took the map and returned to the rocking chair. He unfolded the map with both hands and looked at it slowly. After looking at it for a few minutes, Liang Xi called Fiona. Fiona answered the phone: "Speak." She was busy.

She talks less and gets to the point directly. When she is free, she will always make a few teasing remarks.

Liang Xidao: "I have two maps in my hand, can you find the difference between them?"

Fiona: "Are you insulting me by asking this question? Scan two maps, download a comparison software from the Internet, and let the software compare the maps."

Liang Xi thought for a while: "Scanning means taking pictures? Or scanning like a copy machine? What software is needed, a mobile phone or a computer?"

Fiona said: "You first need an external scanner. Photos are also acceptable, but the requirements for photos are relatively high. Is the map you are talking about a dense paper map?"

Liang Xi replied: "Yes."

Fiona sighed: "Well, you treat me to lunch and I'll take care of it."

Liang Xidao: "I only have one map now, and I don't want to go out and buy a second map. The Internet is omnipotent, right?"

Fiona: "The Internet is omnipotent, but it is not omnipotent."

Liang Xi walked to the window, raised the curtains and looked at the cold rain outside. He didn't know where to find the same map. He thought for a while and said, "How about having dinner?" He really didn't want to go out during the day because of this weird map.

Ruin your good mood for the day.

Fiona: "I'm going to have foie gras tonight."

"Okay." Liang Xi asked, "Can you get a sample map by the way?"

Fiona was speechless for a long time: "Take a photo of the map in your hand and send it to me." That's Liang Xi. If it had been anyone else, it would have been so troublesome to kill him in minutes. Liang Xi was different. Liang Xi was a computer novice in Fiona's eyes.

She is cute and stupid, but too lazy to be stylish.

…

At noon, I went downstairs to the restaurant for lunch. There were not many customers in the restaurant today. I chatted with the waiter and the boss for a while, and made sure that there was no such thing as acquisition. After lunch, I planned to go back and take a nap, but I received a call from Baker, telling him to come over.

pick him up.

Liang Xi replied: "I don't want to go anywhere today."

Baker said: "I'm afraid not, because of the victim, the police detective must see you."

Liang Xidao: "Since I became famous, many people want to see me."

Baker said: "No, it's not the same thing. I'll be there soon."

There is a homeless home near Bonning Street, which is not official. It is similar to feeding stray cats and dogs. The more times you feed them, the number of stray cats and dogs nearby will increase.

, causing stray cats and dogs to gather. If stray cats and dogs attack others

, the feeder has civil liability.). The charity then took advantage of the situation and built a homeless home. In fact, it was a bridge hole next to the bridge pier. People from the charity organization did the drainage, set up a few iron barrels, and delivered some wood. Every day

They will distribute food here, and homeless people can also receive clothing.

Even so, there is only basic survival equipment. Why don't charities build some iron houses and provide free water, electricity and heating? After all, there is not much money. This is a social management issue. In principle, people who do not work must have a lower living standard than those who do not work.

People who work and labor. Only ensuring food and clothing is humanitarian aid. Giving too much is disrespectful to others.

For example, after the legalization of special work for women in Germany, a social problem arose. The problem is not the work itself. The problem is that it hurts women who work normally, seek recognition and pursue self-esteem and self-improvement. An ordinary female worker's weekly income is equivalent to the special worker's daily income.

This income gap between the rich and the poor is likely to cause dissatisfaction among women and turn them into this industry.

There is such a theory in sociology, which roughly means: we need to help the poor survive, but we cannot let the poor live a good life, otherwise everyone will become poor in the future. In developed countries such as Europe, as long as you have a stable job, your life

It won't be very bad. At least it is guaranteed that they will live a better life than those who receive monthly benefits.

Homeless people usually lay paper sheets on the spot and put blankets or clothes on top to make a simple bed. They usually just wrap themselves in bed, make a fire, smoke and drink, chatting or being in a daze, with almost no personal belongings. Some people

Once you have figured it out, you can contact a charity, and the organization will try its best to arrange a job. Most of it will be physical work.

Although there are no personal items, everyone has a treasure box, or a suitcase, or a cardboard box to store their own things. Today, the homeless man Clay is in a good mood. He has earned two hundred pounds. This is three months.

Here comes the first money he earned. After he had money, he considered buying new clothes and hoped to find a suitable job. His physical strength was not good and he had to find a easier job.

After delivering the letter, he met the masked man wearing a top hat again on his way back to the homeless home. The masked man asked him if he had completed his work. After receiving a positive answer, the masked man gave him the bag in his hand. When he opened the bag, he could see

There was a lot of food inside, as well as a box of cigars, a bottle of wine, and two packs of cigarettes. This actually made Claire happy. She returned to the bridge and shared the food, cigarettes, wine, and stories with her companions.

There was a rectangular wooden box at the bottom of the bag. When Claire was about to open it, the gangsters finally appeared. The two gangsters were both tramps, but very strong. Two men rushed up and snatched the bag. Claire came to grab the bag and was killed.

A stomped him to the ground and warned him not to cause trouble. Claire was a newbie among the homeless and had a cowardly character. She was worried that the other party would steal her cash, so she hid aside and did not dare to say a word.

B handed the wooden box to A. A sat down and put the wooden box on his knees. He pressed the buttons on the left and right sides of the wooden box, and the lid popped up. There was a bomb inside. There was a printed note on the back of the lid:

The bomb has been activated. There is also a picture on the note. The picture shows two thin transparent tubes made of glass, with the word mercury written inside. The glass tubes are in the wooden box, one on each side. Look at the picture to understand.

If any pipe tilts, the bomb will explode immediately.

A shouted anxiously: "Bomb explosion." The mercury in a tube shook. A quickly held his breath, and the mercury fell back to the right. The onlookers also saw it clearly one after another. Those who saw it first ran away in panic, and everyone left one after another.

Person B remained loyal and stayed. At Person A's request, he left the bridge and asked for help from a charity organization not far away. After hearing the situation clearly, the volunteers from the charity organization called the police.

Police cars, plainclothes vehicles, ambulances, and fire trucks are here, and the bridge is temporarily blocked. After the explosives are determined by the equivalent, the inspector asked Claire. Claire said the mask wearing a hat man to send him a letter. The police.

Knowing that Liang Zai, he contacted his boss, his boss contacted Liang Zai's friend Baker, Baker answered the phone and drove over to catch people.

After listening to Baker's instructions, the car is about to reach the bridge hole. Liang Xing said: "Go back."

Baker said: "Make at least a record."

Liang Zaidao: "The map is still in the detective agency."

Baker accused: "You don't say early."

Liang Xiang accused: "You didn't ask, what do I know?"

Baker thought for a while, as if he was wrong, he could only turn around.

Liang Zailian is Fiona: "Beauty, I have to be in a hurry."

Fiona: "I'm in the bathroom."

Liang Zaidao: "The map seems to be related to bombing."

Fiona was excited and asked, "The sacred flag?" Come again?

Liang Xiang thought for a while: "It should not be." Liang Xiang thought of Isa and the explosive departments he talked about.

When Liang Xiang thought of this, he suddenly said to Baker: "Makes people far away, that bomb will definitely explode."

Baker asked: "Why?"

Liang Xingdao: "The suspect reminded me that the police reminded the police. He deliberately chose a tramp as the goal, indicating that he did not respect the tramp, indicating that he believed that the tramp can be sacrificed, so the bombing would definitely explode.

There must be a remote control startup system. In addition, the suspect may observe the situation not far from the scene. "
