It's the missing link - the story that ties the Underbelly cast of characters to a series of unsolved crimes that have taunted police and haunted victims' families for decades. That includes at least three brazen heists totalling $6million - and four murders as dark and as daring as any in the history of Australian organised crime.

The story comes from an old friend of Underbelly identity Carl Williams, the one-time suburban burglar who became the powerful drug dealer and gang boss who started the gangland war to avenge himself on his underworld enemies, the Carlton Crew. The old friend of Williams is a professional sportsman (alias 'Jock') who once befriended Williams when they were unknown teenagers. Jock once drove a badly-hurt Williams to hospital after a pub brawl and Williams always trusted him. Jock wasn't a crook but he knew plenty of them: he was a favourite of Tony Mokbel's back when Mokbel carefully cultivated contacts in sports he could bet on.
Mokbel will die in jail and Williams and his violent henchmen Dino Dibra and 'Benji' Veniamin were both shot dead. But Jock has lived to tell the tale of where the bodies are buried.

This is it.
