Part 3

Episode 3

Dan Marshall tracks down Stephanie, first by visiting Joanna Randell unannounced, then by visiting the Sydney house where he meets the two children, Sarah and Dennis. Stephanie, meanwhile, carefully drives Greg and Jilly to distraction until at last Greg tries to kill Jilly. Stephanie then reveals herself to them both. Greg tries at once to kill Stephanie, first by setting fire to a room in the main house at Eden, then in a swimming pool. But Jilly shoots him in the arm, making him bleed profusely. He then attempts to flee in an aeroplane. It crashes and he is killed. The next day the police arrive and arrest Jilly. The day following, another aeroplane lands--carrying Sarah, Dennis, and Dan.
