A novel with a socialist police motif is a subgenre of PRL crime fiction which appeared in the Communist Blok countries. Its characteristic features are as follows: the over-persuasive function, glorification of the socialist police (MO), inspirations which were taken from the poetics of social realism novels, and low literary standards. In fact, the PRL crime fiction constitutes a far more complex phenomenon. Along with ideologically biased novels of poor quality, appear those written at a high, professional level. The latter concerns the authors like Leopold Tyrmand, Andrzej Piwowarczyk and Tadeusz Kostecki. The most popular authors are Zygmunt Zeydler-Zborowski, Jerzy Edigey, Anna Kłodzińska and Helena Sekuła. The writing women, mainly represented by Barbara Gordon, set the female trend in PRL crime fiction, which is worth attention.
