What is the author's style in Sinuhe the Egyptian: A Novel by Mika Waltari?

The narrator of Sinuhe the Egyptian is an educated physician putting down in writing the events of his long and exciting life while in exile from his beloved Thebes. As a prerequisite to studying medicine, he studies to become an entry-level priest of Ammon. He betrays his beloved adoptive parents by lusting for a beautiful woman. He falls in with brigands and with royalty. He travels widely and falls in love with women only to lose them tragically. He sees war. He negotiates peace. He lives as a commoner and preaches the outlawed gospel of Aton, and for this is sent into exile, for his words are powerful enough to be politically dangerous.
