In April 2002, wealthy socialite Margaret Wales-King and her husband Paul King left their home in a leafy eastern suburb, dined with her son and his family and then disappeared into thin air. Twenty-five days later, after an investigation that swamped the front pages, their bludgeoned bodies were found in a shallow bush grave just outside Melbourne. The family's grief was on full public display as speculation raged about the possible culprit and rumours about drugs, gambling and kidnapping did the rounds. Then Margaret's youngest son, Matthew, was arrested for the murders and his wife, Maritza, was charged with attempting to pervert the course of justice.
