Bony and the White Savage [EPUB ebook] 

By a lonely roadside in the south-west corner of Western Australia, old-time Karl Mueller is roused from his drink-sodden sleep by approaching footsteps and the sound of whistling. What he sees on waking (or thinks he sees) is enough to make him stiffen with fear, and more than enough to worry the police into calling for Inspector Napoleon Bonaparte.
The disturber of Mueller’s rest is Marvin Rhudder — once an outstanding theological student, now a convicted rapist and basher, a bloody savage whose recapture will put all of Bony’s sleuthing and tracking skills to the test.
