Postmodern theory of history is about differentiation in classical approaches to literary works via historiographic methods. As an obligatory part of changing world order, this theory suggests constructing literary works over the ambiguities leaping into the eye from the history. Hence, it is necessary to take into account both historical and literary aspects while analyzing the works that are written in conformity to this theory.Initially in the study, the concept of postmodernism is explained so as to meet this requirement, and examples are given to illustrate how and through which practices Erbil embeds this concept in her works. Afterwards, the postmodernist perception of history as well as the theory of history emerging from this perception are described. As historical dimension in the work is shaped around Mustafa Suphi murder, the reader is also informed about Mustafa Suphi and his life. However, this life story is limited to the aspects that are reflected in the work. Postmodern theory of history argues that in novels that are shaped by historical phenomena, socio-cultural contexts that form the phenomena need to be analyzed as well. To this end, the contexts in the work are also taken into account. These contexts are analyzed in the form of political and personal items. The final title of the study dwells on analyses as to why Leyla Erbil narrated the different clues she obtained about the aforementioned case of murder. Therefore, this section also discusses the pluralist perspectives specific to the novel as projected by postmodern theory of history.The main argument of the study is that Leyla Erbil skillfully employs the techniques required by postmodern theory of history
