How to write a novel of criminal investigation and reasoning?

First of all, we should pay attention to a basic point. Criminal investigation and reasoning are different. This is the difference between a detective and a policeman.

Criminal investigation means that criminal research and criminals must be carried out under the constraints of law, while reasoning is not so limited. If the subject has not fully determined the characters in his story, or is unfamiliar with criminal law to a certain extent, your creation will become difficult, or you will slowly lose what you really want to express. It is easy to turn a policeman who is bound by law into a private detective, which deviates from the original intention of the creator.

Therefore, the most important problem is that you can't sell dog meat by hanging sheep's head.

Secondly, dna detection, fingerprint identification and other clues are generally classified as subject level. However, in the overall situation of our country, the research and understanding of micro-science by criminal police in the public security criminal investigation team is generally in the primary stage. In the actual process of handling cases, the research on traces was further refined by setting up a task force.

Of course, the last and most important thing is to have patience and perseverance. The process of novel creation is pleasant and also a headache, because in this process, the author inevitably needs to consult materials and visit repeatedly, and this process of acquiring knowledge and accumulating is actually very happy.

However, with the continuous accumulation and increase of knowledge, a problem often arises, that is, I always want to overthrow what I wrote before. Sometimes I feel ashamed and wonder what kind of fool I used to be.
