I've been on a true crime watching, listening and reading spree these past few months and the latest offering is Cold Case Investigations by leading Forensic Anthropologist Dr Xanthe Mallett. Seven Australian cold cases were selected for this collection and Dr Mallett takes us through each case.

The Wanda Beach murders, the disappearance of the Beaumont children, the abduction of William Tyrrell and the identity of Mr Cruel are well known cold cases in Australia. It is hoped that bringing light to these cases and keeping them in the public eye will eventually lead to a break through.

What surprised me were the other three cases chosen for the book, in which the offenders have already been identified, captured and prosecuted. In particular, I refer to the chapters on Ivan Milat, Daniel Holdom and Ashley Coulston. In these cases, the offender has been sentenced but the author postulates that further cold cases and missing persons could be attributed to these incarcerated offenders. Whilst I have no doubt these perpetrators probably have committed crimes unknown to police, I wouldn't classify them worthy of focus in a book of cold case investigations. If the victims are unknown, how can they be cold cases? Perhaps this is a new category of crime victim worthy of further exploration and its own book.

In addition to these main chapters, Mallett includes sections entitled Forensic Science Explained in shaded and bordered sections reminiscent of Unsolved Australia - Lost Boys, Gone Girls by Justine Ford, also published by Pan Macmillan Australia this year. These sections cover forensic techniques involved in investigating cold cases and include topics like DNA, fingerprinting and blood groups. These sections would be informative and helpful for early readers of true crime, however for seasoned readers like me it was overkill.

Even viewers of the odd TV crime show would be familiar with the science included here and the opportunity to inform the reader of more detailed forensic techniques was lost. I would also presume that the kind of reader picking up a book like this will already possess this kind of foundational knowledge.

Towards the end of the book, there's a section entitled 'But have you ever heard of these missing children?' Here Mallett mentions the disappearance of 11 month old Darren Shannon in 1973, and 19 month old Rahma El-Dennaoiui in 2005. On page 252, the author says:

"A number of journalists have likened Rahma's case to that of Madeleine McCann, but I bet most people would not know Rahma's little face if they saw it."

And she's 100% right, I wouldn't! So why not set things right and include a photo of her in the book? Why publish two photos of well-known missing toddler William Tyrrell and then neglect to educate the reader by including a photo of Rahma?

Dr Xanthe Mallett has had a fascinating - and impressive - career as a forensic criminologist, university lecturer, forensic practitioner, television presenter and now published author. Here she has tried to shed light on Australia's darker side of crime and ultimately seek justice for the victims and their family. I can't help thinking she may have been able to achieve more given the opportunity to expand on the cases, however there is every hope someone reading this book may come forward with information.

Cold Case Investigations by Australian author Dr Xanthe Mallett is recommended reading for those new to the true crime genre and those unfamiliar with solved and unsolved homicide cases in Australia.
