Szukana fraza: [Abstract = "Despite the deep differences between these two novels, it turns out that in the structure of the Łoziński`s novel we can find the elements of the convention of mystery novels, especially in the fragments describing Lvov. The city is shown as a city of \"secrets\". Moreover, the mystery, differently understood in the novel, and related to the history of a stolen diamond, connects all fictional stories. The immutability of a mystery novel depends on the individual decision concerning writing, but one can indicate the common features, determined by the literary premises with regard to the subject`s attractiveness."]
