What is the author's style in The Twelve Caesars by Suetonius?

The book is written completely by Suetonius and is written in a subjective tone. Though he never says where he gets his information from, usually he just refers to stories handed down from generation to generation, and quotes his father once or twice. He writes in such a way that the reader trusts him and does not suspect he is making all of the stories up. His audience seems to be the general public, and that he is hoping to educate them about the men behind the legends and he does a decent job at this. The reader is constantly surprised by the content of the paragraphs and Suetonius really focuses on the different leaders' personal lives more than their professional lives, which is what the book intends.
