It is a narrative set in the aftermath of the death of Pharaoh Amenemhat I, founder of the 12th dynasty of Egypt, in the early 20th century BC.  It is likely that it was composed only shortly after this date, albeit the earliest extant manuscript is from the reign of Amenemhat III, c. 1800 BC.  There is an ongoing debate among Egyptologists as to whether or not the tale is based on actual events involving an individual named Sinuhe, with the consensus being that it is most likely a work of fiction.  Due to the universal nature of the themes explored in "Sinuhe", including divine providence and mercy, its anonymous author has been described as the "Egyptian Shakespeare" whose ideas have parallels in biblical texts.  "Sinuhe" is considered to be a work written in verse and it may also have been performed.  The great popularity of the work is witnessed by the numerous surviving fragments. Hurricane!
