Mystery and mystery texts dominate Terra nostra, Fuentes’ novel about absolute authority. Both El Señor, the protagonist who covets eternal power, and Fuentes, the author who appears to assert his privilege through the fiction, are betrayed by their own strategies. Failing to recognize his inability to exert absolute control over history, El Señor, trying to master a set of mysterious texts he believes hold the key to his power, attempts to mold reality to his own desires. Although Fuentes understands the impossibility of creating a truly simultaneous text, he nevertheless tries to realize his plan through the novel’s complex narrative network. That network, however, needs the support of a linear mystery fiction, which thwarts the reader’s desire for solutions but fails to triumph over the bounds of literature itself. Thus the assertions of absolute authority by El Señor and Fuentes reveal the very powerlessness they would disprove.
