In popular culture In 2003, Melbourne barrister Hilary Bonney wrote a book about the murder, The Society Murders: The True Story of the Wales-King Murders. The book was written without co-operation from the Wales-King family and was based largely on court evidence and police documents. The book was later adapted as a 2006 television film, The Society Murders for Network Ten, written by Greg Haddrick and Kylie Needham for the production company Screentime. The film starred Georgie Parker, Alex Dimitriades, Matthew Le Nevez, Terry Norris and Julia Blake. The story was also examined on the episode "The Enemy Within" of the series Behind Mansion Walls presented on Investigation Discovery.
