Who really murdered Bob Chappell? Veteran ex-detective and author of JFK: The Smoking Gun, Colin McLaren, uncovers disturbing new evidence that an innocent woman is in jail.

Daybreak, Sandy Bay, Hobart, 27 January 2009. A yacht, the Four Winds, is seen listing low to the waterline. When police board the sinking vessel there is no sign of the owners, Bob Chappell and Sue Neill-Fraser but, disturbingly, they find blood and a knife.

Bob Chappell is never seen again. The blood spatter leads police to the conclusion that he has been murdered. Remarkably, Sue Neill-Fraser is arrested, found guilty and sentenced to 26 years'' imprisonment.

May, 2016. Bestselling true-crime author Colin McLaren probes the notorious cold case that grips Australia. What he discovers shocks him. No body, no motive, no witnesses, a puddle of unexplained DNA liquid, undisclosed police documents, insubstantial scenarios - all lead him to believe Sue Neill-Fraser was wrongly convicted. He is not alone, as lawyers line up to help her.

August 2017. Sue Neill-Fraser remains in prison. When questions are asked of her conviction, new witnesses are charged, including a lawyer, and unbearable pressure is applied until, fearing for his own liberty, Colin McLaren flees the country. Southern Justice lays out the evidence that should force a Royal Commission to reopen the case and exonerate an innocent woman.

The guilty are still out there!
