Detective novel is called "intelligent literature", which combines science and technology, legal system and humanistic spirit. They are widely read all over the world with tortuous plots, strong suspense and rigorous logic, and are rare bestsellers in world literature.
From children's point of view, children's novels are full of children's interests, can fully meet children's aesthetic needs, conform to children's curious and active psychological and behavioral characteristics, take social life as the content, and are very imaginative and story-telling. The content is healthy, and there are no elements such as blood, terror, feudal superstition, pornography and violence that are not suitable for minors.
It is said that the first literary works read by American children are often detective novels.
