The true story of baby Tegan Lane who went missing in 1996 and is now presumed dead.

Keli Lane, Australian water polo champion and elite private school teacher had it all -- a privileged social life on Sydney's Northern Beaches, a tightly knit circle of friends and a rugby hero for a boyfriend -- until her hidden double life was exposed.

In secret, Keli carried three babies to term, giving birth on her own each time. Incredibly, her family, friends, colleagues -- even her boyfriend -- had no idea. Two babies were adopted but one, Tegan, disappeared without a trace. In December 2010, Keli Lane was found guilty of murder.

In this probing, investigative work, journalist Rachel Chin sifts through Keli's background and the compelling drama that unfolded daily in the coronial inquest and criminal trial for answers to this baffling case. Who is Tegan's father? Why did Keli keep her pregnancies and births secret -- and how could her family and friends not know?

Nice Girl explores all these questions and more, revealing a dark and bizarre story of secrets and lies.
