Some of the crimes examined in "Unsolved Crimes: The Crimes That Haunt Australia" are well known - for example the Beaumont children, the Daniel Morcombe case, Mr Cruel in Melbourne and the Claremont murders in Perth in the 1990s. However I was surprised at how many I had not heard of. So while this was an interesting book, it was also very sad to read about just how many young people (children in particular) have disappeared or been murdered in our fairly recent history.
One thing I did realise after reading this book was that the murder rate (of the random victim kind at least) has apparently declined over the past decade or two. Also given that hitchhiking is now almost unheard of (especially for women) and parents are much more protective of their children, the opportunities for opportunistic predators have declined markedly. I was also very interested in the string of crimes that may possibly be attributed to Ivan Milat - but which, given his incarceration for life will never be brought to trial.
Overall a sad, yet interesting summary of horrific unsolved crimes in the lucky country.
