This work is based on the analysis of prison prose by Tomislav Marijan Bilosnić in relation to world prison prose. The novels Tight space and Stick in the river Zrmanja were analyzed. The coincidences are visible in the realist-historical context, more precisely in the dictation and conditioning of freedom by one of the political systems. Criminals and political dissidents were sent to prison with the aim of changing upbringing, which ultimately resulted in reflections on the essence of their own intimacy and existence. It is important to see who is in prison for a reason, and who became its victim just because of a different way of thinking. Humans and non-humans have created a conflict with each other. Following the individual destinies of the protagonists of these novels, the reader comes to the realization that justification for immorality and sin must not exist, and the only things that can free a sinner from the jaws of evil are true penance and remorse.
