FROM BRISBANE'S SLEAZY 'SIN TRIANGLE' TO DRUG BUSTS IN THE WILD FAR NORTH, FORMER UNDERCOVER COP DOMENICO 'MICK' CACCIOLA TELLS HIS INCREDIBLE TALE OF UNDERWORLD CRIME AND POLICE CORRUPTION. In the 1950s Mick's family migrated to Australia from war-torn Italy and, in the Sicilian tradition, as the eldest of four boys, he was considered 'il secondo padre', the second father. Growing up with racism and discrimination compelled him into a life fighting for justice and honour. After joining the Queensland Police force in the 1960s, Mick became a 'sleeper', risking his life infiltrating illegal gambling dens. In the 1970s he saw the ugly face of entrenched corruption while working in the seedy Licensing Branch. In these turbulent days - before the corruption-busting Fitzgerald Inquiry - he waged a long and bitter battle with now disgraced police commissioner Terry Lewis and the infamous bagman Sergeant Jack Herbert. Later, as a Special Branch detective, he spied on suspected Communists and used his muscle to break up illegal street marches. In THE SECOND FATHER Domenico Cacciola breaks a 35-year silence to tell the truth behind Australia's most notorious era of crime and corruption.
