For more than 30 years, the name Mr Cruel has haunted Melbourne. 

He was meticulous, terrifying and seemingly vanished without a trace — leaving behind one of Australia’s most disturbing unsolved crime mysteries. But in this gripping six-part investigation, Adam Shand uncovers secret forensic evidence that challenges everything police thought they knew about the case. 

Across the series, we revisit the abductions, the fear that gripped suburban Melbourne, the assumptions that shaped the investigation, and the hidden evidence that may overturn them all.
