This study was aimed at analysizing the diverse aspects of excellent self-consciousness of modern city-space, creating shapes of detective on Nae-Seong Kim’s detective novel adaptation of 〈Night Breed〉, 〈The White-Headed League〉. Nae-Seong Kim presented Arthur Conan Doyle’s 〈The Adventure of Speckled Band〉, 〈The Red-Headed League〉 with his name next to ‘adaptation’. Translated and adapted novels arranged riddle tales and lawsuit type stories in middle age for modern detective novels, so they could help to form the taste of detective novel. The elites wanted to satisfy their intellectual desire through detective novels and popular readers were fascinated to western civilization. The translation work of series of Sherlock Holmes, which were introduced to Korea during the colonial period, used a variety of language to state the status of translation but it was more like ‘adaptation’. Holmes’s acclaimed science of detection is characterized by the reasoning power which seems uncontaminated by his personal bias or emotional involvement. The literary detective’s methods, invested with machine-like precision, are presented to us as empirical and objective. The detective novel is entirely the product of modern city. In detective novels, detective have good command of demanding inductive reasoning and scientific knowledge to solve the crimes, because they had been based on the genre pattern of the western classical detective novels. He traced not only city’s surface but also city’s glittering facade, makes a strong appearance of the ‘Flaneuse’, collector, thinking machine, is defined as an his ability to figures out the cryptic clues with independent rationality and individuality.
The colonial period, physical conditions of modern city is allowed as a mere formality, but practical experience and edifice, substance of place, is in poor condition. As a major text, Gyeongseong that is no such thing as a purely specific origin and identity, that could well are very disorderly to decipher the codes of space elements. Gyeongseong in Nae-Seong Kim’s detective novel adaptation, is only the imaginative city adaptation of London. The detective in Korean detective novels is searching not only for reality, but what lies beyond this, because so many things in their own age has failed them. Korean detective novels in the colonial period was fated to be on the horns of a dilemma that be enforced to engages in creative writing on poor setting of the story. Nae-Seong Kim’s detective novel is the story of ‘detective of end in failure’. Detective can’t rescue the a lot of victims, not find out crime-tricks. In some way, it is natural for him to failure, because space of detective novel is made up transcendental cognition. There were considerable gap between self-consciousness of modern city-space, modern science, modern cognitive structure, modern type of life and Korea, which could not be filled.
