What is the author's style in Sacred Hunger by Barry Unsworth?

Along with third person omniscient perspective, dialogue between characters is used. Within this dialogue various accents and dialects are detected through the use of phonetic spelling. The language of the upper class is shown through the use of correct grammar and spelling, as well as a large vocabulary. Scottish, Irish, Cockney, and African accents are created by adjusting the order of words and the spelling of words to better match the sound of each accent.
