Tldr: in the 60s in the Northern Territory an Australian Federal Police Officer discovered that a young aboriginal girl was abducted, used for sex and murdered by a person he believed was Sir Harry Talbot Gibbs (who became Chief Justice of the High Court of Australia). He also suspected that another young aboriginal girl was abducted by Senator Lionel Murphy (who later became Attorney General).
