A dugout or dug-out, also known as a pithouse, pit-house, earth lodge, mud hut, is a shelter for humans or domesticated animals and livestock based on a hole or depression dug into the ground. These structures are one of the most ancient types of human housing known to archeologists. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. The same methods have evolved into modern "earth shelter" technology.

Dugouts may also be temporary shelters constructed as an aid to specific activities, e.g., during warfare or in hunting.

Coober Pedy is a small town in northern South Australia, 846 kilometres north of Adelaide on the Stuart Highway. Located in the Australian outback, the harsh summer temperatures and the dominant industry mean that most residents live in caves excavated into the hillsides and work underground in mine shafts. White Cliffs, New South Wales is similar, both in terms of climate and mining operations.

Twenty years prior to the novel's events, twelve year-old Adam and his two best friends failed to come home after playing in the familiar woods bordering their Irish housing estate. A search is called by the families, and the police find Adam shivering, clawing the bark of a nearby tree, blood on his shoes and slash marks on his back. He is unable to tell them what happened or where his friends are. His amnesia holds to the present day, where he goes by his middle name, Rob, to avoid the attention of the media to his famous case. His friends were never found.

The plot of the novel circles around the murder of a twelve year old girl, Katy Devlin, whose case Rob and his partner Cassie Maddox are given to investigate. The body is found in the same woods where Rob’s friends disappeared, at an archeological dig site, and the coincidence is enough to make Rob nervous, though he insists to his partner that he is fine.
