Owen and Pemberton’s fascination with Devils is made apparent through the detailed literary references made to complement the scientific research. They have included personal anecdotes as well as public and private pieces of writing about the Devil, which speak to its unique nature. A choice one is that Devils prefer to sleep on freshly cleaned clothing or bedsheets: one Devil boldly pilfered an entire junior soccer teams’ jumpers to line its den. The authors describe a number of threats the Devil has faced throughout the years, from man and nature. Threats from government culls, furriers, the development of roadways, pollution and environmental degradation pale when compared to the effects of Devil Facial Tumour Disease (DFTD), which is covered in detail. Perhaps this was the impetus for writing the book, as the Devil population is threatened with extinction again; at the time of writing, it was uncertain whether human help would secure its continued existence. However, the authors must have been heartened to hear of the recent developments in DFTD research regarding methods of contamination, which will result in specially isolated communities of Devils remaining safe and ultimately ensuring the continuity of the species.
