The pyjama girl was an unknown woman, found dumped by a road nesrl Albury in 1934. She had been brutally murdered. Who was she, and who killed her, become Australia's great unsolved crime for decades. The body was preserved in formalin, her image circulated around the world. The mystery fascinated the nation and, for some, became an obsession. Ten years later, the body was identified and a man was convicted of her manslaughter. The case, it seemed, was neatlty solved. But this 'solution', advanced by police, accepted by the courts and the media, and since repeated endlessly, was a lie. Behind the lie is a troubling story of murder and obsession, of a wild conspiracy theory, of police corruption and a miscarriage of justice, and of a real killing which floated free from reality and became a myth.
