This essay about political fiction, popular musical biography, psychological reflection and, in the final chapter, "A dead-end universe", science-fiction, pushes the limits of fiction and makes in the field of literary essays, whose territory is always characterized by terminology problems, at the edge of pure concepts, which are to be found in other essays that aren't expressly apparent here: philosophical essays. One thread that runs through these complementary chapters as tree models is that related approaches create the unity of this essay around high standards, individualism, intellectual rigor and disillusionment. The Last Falls metaphor, explaining the title of the work, is reflected in incomplete elements of truth, which exist in many areas and condemn the exercise undertaken to synthetize information to certain failure.
