 The former involves the narrative presented to the reader by the author or the actual story as it happened in chronological order while the latter focuses on the underlying substance or material of the narrative.The double narrative has a deep structure but is specific, particularly when it comes to time and a split gaze on the narrative itself.The two tales coexist and interweave with the first tale focusing on the crime itself, what led to it, and the investigation to solve it while the second story is all about the reconstruction of the crime.
