How does the author use foreshadowing in The Collected Tales of Nikolai Gogol?

The titles alone hint at a different style applied to each set. The "Ukrainian Tales" are written earlier and are rich in description and complicated sentence structure. The second set "Petersburg Tales" is written later on in Gogol's career and underscore a transitional style which is noticeably more contemporary and succinct. Gogol employs a device of having multiple storytellers relate the tale. By layering on more than one storyteller it provides the mystique that perhaps some of the details may be incorrect. Gogol is playing with the reader, intimating that there may be missing pieces to the story.
