From bewildered to furious, Chris and Paul Dawson vent their true feelings in tapped phone calls over two decades, as the lingering mystery of Lyn’s disappearance draws the attention of police, journalists and the wider world. Retired detective inspector of homicide Gary Jubelin takes us inside the emotion and suspense of a murder trial, and defence lawyer Karen Espiner breaks down the tactical decisions and judicial process at play. Plus, an evocative exploration of Lyn’s family and their long wait for answers. To read The Australian's ongoing coverage of the trial search The Teacher's Trial or click here.
