A hellish war. A deadly secret. Fifty years on, in a small Tasmanian town, the truth unfolds and the killing begins again …

Betrayal cannot be buried forever.

In the tiny Tasmanian town of Mole Creek, retired Australian cop and Vietnam veteran Pete McAuslan has retreated to his fishing cabin to write his memoirs. In Sydney, his grandson, journalist and trashy true crime author Xander, learns that Pete has taken his own life, begging forgiveness in a suicide note.

Arriving in Mole Creek in the aftermath of Pete's death, Xander discovers that his grandfather's laptop is missing. He begins to suspect that something is wrong, refusing to accept the facts as presented. With the local police not interested in investigating an apparently open-and-shut suicide, Xander sets about uncovering the truth of what happened to his grandfather.

In the process, he discovers long-buried secrets from Pete's time serving in the Vietnam war: secrets that Pete has withheld from him and everyone else for fifty years; secrets that powerful people would prefer to stay buried. Ensnared in a web of betrayals that began a generation before, Xander finds himself on the hitlist of a clinically violent assassin. Now he must race to identify the connection between the seemingly unremarkable death of an old Australian soldier and the imminent reactivation of the most powerful and potentially destructive 'sleeper' in the history of espionage – before the truth catches up with him.
