Before Carl Williams, there was Trimbole: race fixer, drug boss, Mafia powerbroker, murder contractor and arms dealer. In the 1970s he and the Calabrian Mafia ruled Australia’s marijuana trade from their Castles in Griffith – dream homes built on drug money. The business expanded to heroin when Trimbole joined Terry Clark and the notorious Mr Asia syndicate, and then to murder when anti-drugs campaigner Donald Mackay blew the whistle. Here is never-before published material gathered by Walkley Award-winning journalist Keith Moor, covering the truth behind Mackay’s disappearance, interviews with supergrass Gianfranco Tizzoni as well as a top cop. There are excerpts from an unpublished memoir by Mackay’s widow and a dossier on the involvement of controversial federal minister Al Grassby. Illustrated with black and white photos.
