I like these sorts of true crime books as fill-ins, especially if I've recently read a few hefty fictional tomes.
From the Blurb:
This revised, expanded collection of true crime by Australia's foremost crime writers digs beneath the polite exterior of modern Australian life to expose its chilling core.
Australia is a lucky country. By world standards we are safe, secure and affluent. We have been spared widespread racial violence and our crime rate remains relatively low. But there is a thread of violence through the fabric of this seemingly civilised society that began with the arrival of the convicts on the First Fleet.
