what techniques does johnson use in this chapterto create suspense?

The narrator is extremely adaptable in all of his jobs and locales, and “his only constant, essential characteristic is that he possesses no constant, essential characteristic.” Johnson even avoids giving the narrator and most of the other characters real names, identifying them by their physical characteristics or jobs. Traditionally, white masters had the authority to name their slaves, but after emancipation, African Americans reclaimed autonomy by un-naming or re-naming themselves. The narrator avoids being controlled by either tradition and creates a system of identification based neither on the slaveowners' tradition or by rebelling against it.
