Following the success of their bestselling Gangland Australia, James Morton and Susanna Lobez turn their attention to crime and criminals, both organised and disorganised, in Australia and New Zealand over the last century.Dangerous to Know documents murderers known and not so well known, conmen and their victims, street gangs of the early twentieth century, crime lords of the 1920s, dock warlords of the 1970s, bikers, sex offenders and the drug gangs of today, as well as the wrongly accused and wrongly convicted. They're all here, as well as the police, lawyers and judges who have tried to deal with them.
