This study analyzes the narrative strategies that form a poetics that destabilizes the heteronormative patriarchy of the posthumous novel Tadeys (1983) by Osvaldo Lamborghini. The strategies disassemble the patriarchal conception of the body, as it is built as a flow of urges where subjectivities are installed-artificial prosthesis-designed by La Comarca State. One of the narrative strategies is the making of male characters motivated by primary drives in a patriarchal country. In this sense, the patriarchal order sets as a cynical mask always transgressed by the homoerotic desire of the ambivalent characters. The second narrative strategy is the deconstruction of the female gender with the incorporation of the prison La Roca, symbolic space where the male criminal body is transformed into a docile woman ready to get married. In this prison, the female gender represents and reproduces as performance, it lacks of an essence a priori, as it is the product of the institutions that create it, regulate it and naturalize it.
