1. Focus
To be a detective, a high degree of concentration is absolutely indispensable, but just frowning and thinking at any time is not enough. Being too nervous will reveal important things. "Thinking deeply" and "thinking hard" are completely different. Only when all the necessary reasoning materials are complete can we enter the homework of "deep thinking", and switching this program smoothly requires excellent attention.
2. Have keen observation.
All criminals try to cover up their crimes and don't leave evidence where anyone can easily get it, but usually the facts can't be completely covered up. You can find some clues with keen observation. The so-called famous detective is nothing more than finding clues hidden in the crime scene or confession that ordinary people will miss. Therefore, observation is the source of reasoning.
Enrich yourself
Most people always think that the detective's reasoning is only possible if it goes beyond ordinary people's intuition and infinite imagination. In fact, this is a big misunderstanding. Of course, intuition is one of the most important factors, but for a detective, it is more important to have rich knowledge. Sherlock Holmes, with his keen intuition and excellent mind, became the first famous detective in the world. Because his knowledge is as much as that of chemistry, poison and anatomist.
Don't forget your curiosity.
Curiosity is the source of energy for detectives. Especially when there is a trace of doubt about the crime scene or the actions of key people, we must trace it to the end. In our daily life, many things have become a matter of course. If you are used to this kind of "taking for granted", you can't become a detective and explore things that make you doubt.
5. Have a good memory
The so-called complex things must be composed of strange factors and complex interpersonal relationships. If you can find clues and hidden facts in a complicated maze, you can become a real detective. To solve a difficult event, Superman's memory is essential. You must remember what happened at the time of the incident and what the relevant people said unintentionally.
It should also be pointed out that:
0 1. Strictly keep secrets, and keep the secrets of the client.
Don't take bribes, justice is more important than money.
03. Even if the search is fruitless, don't pity your bones and muscles.
04. Don't be preconceived. Only conclusive evidence is a fact.
05. Don't write inaccurate investigation report.
06, don't be moved by an affair, reason is better than emotion when you act.
07. Self-defense techniques such as judo and karate should be mastered.
Knowledge of psychology, forensic medicine and forensic science is also essential.
09, keen observation. Moreover, we can scientifically observe the meteorological conditions and the special situation at the scene, because some evidence will disappear and change with the passage of time.
10, I have a direct feeling and see through the truth through an inconspicuous material evidence.
1 1, relying on rich imagination, reasoning and reappearing various means of committing crimes.
obey rules
1. Keep it strictly confidential. Strictly keep the secret of the head of household. If it gets out, you will lose your credibility as a detective.
2. It is forbidden to accept bribes.
Even in vain, don't be lazy.
4. Reason is better than emotion.
Don't judge things by subjective opinions. Only the facts with evidence are true.
6. You must learn some self-defense skills. For example, Conan can play football and Holmes can play western swords. ...
7. Familiar with psychology, especially criminal psychology.
8. There must be forensic medicine, forensic medicine and other foundations.
9. The investigation report must be recorded in detail.
10. When investigating in a team, you must never rob yourself.
1 1. Be good at observing. For example, when Holmes went up the stairs, he counted the number of stairs. When he went to Watson's house, he also measured how thin his stairs were.
12. You have a good relationship with people, and many times you may take advantage of their occupations (such as doctor, criminal police, driver, reporter) ........................................................................................................................
Small technique
1. When tracking, be careful of your own shadow, it may expose you.
2. If you don't want to be found, you can walk beside the old stairs to avoid creaking.
If you want to confirm whether this person has gone out, put a small note at the bottom of the door, just like putting up a small advertisement!
A bad cold, or a handkerchief on the receiver, will make your voice hard to recognize (unless you have Conan's voice changer).
Throwing peanut shells on the ground can warn people to approach, but it does not meet the requirements of environmental protection.
6. Pretend to read a book and put a mirror in it, so that you can turn your back on the suspect and observe his actions.
If you find the key in the lock, but the door is locked, you can put a newspaper under the door, then poke the key down with iron wire and take out the newspaper.
8. The newly dug grass is different from the surrounding color, and the water permeates quickly.
If you go into the darkness from a bright room, close your eyes 10 seconds. You will get used to the dark environment. But I don't know if your eyesight will be greatly improved if you close your eyes 1 hour, but I know that the prisoner has taken a bath, eaten and escaped without a trace.
10. If you want to have reverse thinking, for example, the code word is "thin pirates will laugh", then you should immediately think that fat pirates will cry.
1 1 When you identify the prisoner, when the prisoner asks you questions before being arrested, you should quickly reflect his intentions and don't tell him the truth directly.
Five principles
"Invisible man" principle
Clumsy detectives are always self-defeating, and they are either dumped by the stalker or followed by the other side, making a fool of themselves. Most of the problems lie in rushing for success and following too closely. As a result, haste makes waste. Learning how to keep an effective distance from the target is one of the skills of private detectives. Never let the stalker feel your existence, let alone let him/her see you, or he/she will be defeated. In order to keep your secret image, you should learn to disguise yourself, just like Stephen Chow's "The Amazing Star".
The principle of "knowing many stars"
Now many advanced trackers have been invented, just like in James Bond movies, even glasses can be used as miniature camera. But we have to improvise. A woman asked a private detective to follow her husband because she suspected that he had gone off the rails. As a result, the private investigator found that her husband frequented gay bars. One day, the detective followed him and wanted to take pictures. The woman's husband thought that the detective was also a kindred spirit, so the detective had to improvise and filmed the whole gay scene. If the detective is not smart enough, I'm afraid he will get a good punch.
The principle of "multiple identities"
If you knock on the door and say that you want to inquire about someone, they are probably too lazy to waste their breath with you. To be a private investigator, you must know how to use multiple identities. For example, tell the housewife that you are an employee of a real estate management company, so that you can talk to people by patrolling the house and get information that you can't get at ordinary times. Multiple identities mean multiple perspectives of information, which is of great help to your intelligence quality.
"Intuition" principle
An experienced private detective found that most of the clients entrusted them to investigate were some kind of doubts, which proved to be not groundless and people's intuition was surprisingly accurate! The wife may not have conclusive evidence to prove her husband's misconduct outside, but her intuition tells her that something has happened or will happen. Detectives should also trust their intuition and have the wisdom to see through people's hearts: as long as they look into the eyes of the Lord, they will know whether what the other party is saying is true or not. Then according to this intuition, try to find evidence along this clue. After all, evidence is the key, because no judge can accept the statement that "I have a feeling that he killed someone".
"Doubt" principle
No matter how complicated and tricky a case is, when you are not sure who the suspect is, remember one thing: the ultimate beneficiary of the whole case is the most suspected. Most mystery novels are like this, and in fact they are. Because everyone has a "purpose".
