German South West Africa 1906, Australian horse trader Cyril Blake is executed in cold blood by the Kaiser's soldiers.
Sydney, the present day. Blake's great nephew, recently widowed Nick Eatwell, is approached by South African journalist Susan Vidler who is investigating his ancestor's mysterious demise.
Intrigued and looking for distraction, Nick discovers a long-lost manuscript which tells how Blake stayed in South Africa after serving in the Anglo-Boer War and joined the Nama people in their rebellion against the Germans in South West Africa, modern-day Namibia.
In Munich, historian Anja Berghoff, researching the origin of the wild 'ghost' horses of Namibia, stumbles across intriguing letters from Irish-German spy Claire Martin, with whom Blake had an affair.
As Nick and Anja's paths cross, they find themselves racing through southern Africa, and through time, on the trail of a legend.
But they're not alone. Someone else is chasing these ghosts of the past, looking for clues for a hidden treasure worth killing for.
Ghosts of the Past is based on a true story.
