The author stated in the study introduction that the social and literary crisis in the period of schematism, which suppressed 'low', entertaining genres as 'bourgeois relic', had also its non intentional positive consequences on writing on crime story. In the 60s of the 20th century following boom of publishing detective novels brought also a need of their defence, what happened with help of scholarly reflection on literary scholarship (J. Skvorecky, J. Zabrana, F. Jungwirth, K. Földvari, R. Stukovsky, V. Petrik, T. Schwarz, E. Klinger and the others). The author comes to the 'basement' of a detective genre in the study and makes analysis of literary courses of Nick Carter, Tom Shark and Leon Clifton. He analysis e.g. Tom Shark's stories keeping the schemes of classical type of a crime story: a criminal is always mysterious, then narrative block follows the investigation (in 'Tom Shark's like stories' adventurous and dominant in all composition) and finally the criminal is disclosed in scene presenting solution as one of the participating characters, usually 'the least-likely person'. In spite of classical crime story those stories do not follow the fair play rules, articulated by former establishers of the detective genre. Nowadays thrillers become close to 'Tom Shark's like stories', of course, they are more worked out in plot and in stylistics.
