What is the author's style in The Egyptologist by Arthur Phillips?

The author succeeds in giving each character a strong and unique voice. Ralph likes to make things sound better than they are, and he has a knack for drama and detail. Ferrell blows his own horn loudly and steadily while insulting the intelligence of all around him. Margaret displays the Roaring Twenties fun-time little rich girl when the opium has not put her into a narcotic fog. Ralph comes across as a well-meaning and enthusiastic young scholar who has no idea how he irritates other scholars, other than they must be jealous of him. In reality, the other scholars see him as a fraud and embarrassment. Ferrell's condescension glares from the page, and his personality stomps through the prose, leaving prejudiced gumshoe marks.
