On 24 September, 2002, Queensland mother Dianne Brimble was found dead on the floor of a cabin on the cruise ship Pacific Sky, less than 24 hours into what was to be the holiday of a lifetime. A police investigation, a high-profile inquest, a grieving family and a criminal trial probed what went on in those few crucial early morning hours ending in her death. This extraordinary case, which captivated Australia, highlights the lines between criminal and moral responsibility and how easily things can get out of hand when care is abandoned.
