Structuralism, as a school in linguistics and humanities, plays a prominent role in the analysis of narrative types. "Roland Barthes" as one of the most prominent inheritors of structuralism with several planning theories around narratology, introduced structuralists to new achievements in the analysis of texts. He revealed the distinction of "Texts Types" by using the "Five Codes" approach. In this distinction, texts are divided into two categories: "Readable" and "Writable". Facing each of these two texts, the audience is placed in a "Passive" or "Dynamic" position. "Five Codes" and its quality in the text clearly reveal the distinction between these two texts and the two readers. In the meantime, Persian fictional literature and especially the Sacred Defense Literature can also be placed in the place of reviews such as "Comparison of Texts" and "Five Codes Analysis". The present research, with a descriptive-analytical analysis and based on the short story "I am the killer of your son" written by "Ahmed Dehghan", through the approach of "Five Codes" seeks to investigate the structures that shape this work. According to the results of this research, the current literature in the text of the story is primarily dependent on "Hermeneutic Codes". These codes play a fundamental role in creating tension and suspense in the story, and the codes "Proairetic" and "Semantic" also reveal the rich story functions and descriptions along with this feature. As the low frequency of "Symbolic Codes" and "Cultural" indicates the realistic approach of the story.
