When a palliative care doctor and her husband and two children are all found dead in a grisly tableau on their living room sofa, the Police ask Professor T to help them decipher how they died, in what order and at whose hands. Is it a text-book case of ‘familicide', in which one of the parents has murdered their partner and children or was a disgruntled third-party involved, given the doctor's outspoken support for assisted killing to let her patients die with dignity? As the investigation proceeds, Lisa is forced to confront the truth about her father's dementia and she finally shares it with Dan, bringing them closer together than ever. Challenged by Dr Helena to face his fears about his past, Professor T enlists help from Adelaide and Ms. Snares to confront his phobia of intimacy, but with extremely mixed results.
