Detective Inspector Napoleon Bonaparte is summoned to the remote Australian outback to investigate the disappearance of a man and the subsequent discovery of a mysterious, savage figure. Bonaparte must navigate the harsh, unforgiving landscape and the complex social dynamics of the local settlers to uncover the truth behind the disappearance. He faces resistance from those who prefer to keep the secrets of the bush buried, relying on his unique blend of indigenous tracking skills and modern police methodology. The narrative unfolds through a third-person perspective that emphasizes the isolation of the setting and the methodical nature of Bonaparte's investigation.

Arthur Upfield's work is recognized for its pioneering role in integrating indigenous Australian knowledge into the detective genre. The series is often noted for its atmospheric depiction of the outback, which serves as both a backdrop and a primary antagonist for the characters. Readers typically appreciate the intellectual rigor of Bonaparte's investigative process, which stands in contrast to the more conventional police procedurals of the era. While the cultural depictions reflect the period in which they were written, the technical skill in constructing the mystery remains a focal point for enthusiasts of classic crime fiction.
