A.B. Patterson is an "Australian writer who knows first-hand about corruption, power, crime and sex. He was a Detective Sergeant in the WA Police, working in paedophilia and vice, and later was a Chief Investigator with the NSW Independent Commission Against Corruption." A.B. Patterson is the author of Harry's World.

According to the book description of Harry's World, "PI Harry Kenmare is a prehistoric private detective in an unfriendly and infinitely unjust modern world. His life revolves around drinking, fine food, smoking, and fast women, preferably the ones he has to pay for, in cash. So what better CV for trawling through Sydneys corrupt social and political elites, who cravenly chase power and wealth behind veneers of respectability. In this collection of seedy episodes, Harry is a dinosaur on a mission of justice, looking to shatter the hypocritical façades. And the rules dont always apply. Join Harry in the jungle of 21st century Port Jackson, where little is as it seems and none of it is pretty. Except, of course, those gorgeous by the hour girls."
