On 4 July 1975, Juanita Nielsen, the chic heiress and newspaper publisher, had a business meeting with a man called Eddie Trigg, a manager at the seedy Carousel Cabaret nightclub in Kings Cross. The following day, Juanita was reported missing. Despite two police investigations, a coronial inquest and a federal parliament inquiry, the disappearance of Juanita Nielsen remains one of Australia's great unsolved murder mysteries. This is an unflinching examination of this cold case and its chief protagonists, not least Juanita Nielsen. An ardent campaigner fighting the proposed demolition of historic houses in the Cross, she was a thorn in the side of a powerful property developer with links to notorious crime bosses.
