Over years of investigation and research, Mullins and former South Australia Police (SAPOL) detective Bill Hayes identified the man whom they and others believe is likely to have abducted and murdered the Beaumont children. A man who stands head and shoulders above all others and against whom the circumstantial evidence is compelling and overwhelming. That man is Harry Phipps. A pillar of old Adelaide society. A man of wealth, power, influence and standing in the community. A well-respected businessman. A family patriarch, charming, persuasive, charismatic. On the surface a gentleman, but in reality, a vicious, manipulative and cunning predator. Behind the walls of his Glenelg mansion resided a violent serial sexual predator with a penchant for deviant pleasures gained from wearing satin clothing and cross-dressing. Harry Phipps was a wolf dressed in sheep’s clothing hidden under a cloak of respectability.
The investigation into Phipps was not carried out by the SAPOL Major Crime Branch. It was conducted by two men who have fought to see justice done for the Beaumont family. Unmasking the killer of the missing Beaumont children is the story of Mullins’ and Hayes’ relentless, determined and focused investigation that finally exposes Harry Phipps as the clear suspect in the most famous cold case in Australian history.
