It's almost 20 years since Australian Story first spoke to the family of former nurse and childcare worker Lyn Dawson. The much-loved mother-of-two was living on Sydney's northern beaches when she vanished in suspicious circumstances 40 years ago.

Monday, we go behind the scenes with Lyn's family and friends as they wait for a verdict that gripped the nation.
