The best Helen Morse’s mystery movies

In the early 1900s, Miranda attends a girls boarding school in Australia. One Valentine's Day, the school's typically strict headmistress treats the girls to a picnic field trip to an unusual but scenic volcanic formation called Hanging Rock.

Melbourne, 1886. Two gentlemen climb into a hansom cab late one murky night. One man climbs out, the other travels on to St Kilda. On arrival, the driver finds the second man dead; murdered. The ‘high-society’ killing sends shockwaves through the young city, still flush from its gold-rush boom.

With Australia at war in Vietnam in 1967, suddenly Prime Minister Harold Holt disappeared without a trace—an event unparalleled in the history of western democracy. Four decades later, a coronial inquiry confirmed that Harold Holt had accidentally drowned. Some people may still believe that Holt was a spy and fled to China in a submarine. But most suspect there was more to his disappearance than has ever been revealed. Reconstructed from eyewitness accounts, this dramatised documentary tells the story of the Prime Minister's secret world in the months before he disappeared — a world of betrayal, blackmail, political treachery, a poisonous feud, mounting physical and mental strain, and near-death experiences. Featuring Normie Rowe as Harold Holt, Nicholas Hope as William McMahon and Tony Llewellyn-Jones as John McEwen, this film reveals explosive new aspects of the case.
