When in 1971 James and Katrina Martin take a short local leave trip from Zambia across the Zambezi into Botswana, they have no idea that they will run into a distant relative of Katrina’s or that they will cross paths several times with ivory poachers. James and Katrina go on an expedition into the Kalahari Desert to retrieve an item buried there by one of Katrina’s ancestors.
On their return they meet with Piet Englebrecht, the distant cousin of Katrina’s who runs a safari business in northern Botswana, near the border with what was then South West Africa. They are invited by Piet to join him and his guests for a week in the bush. While they are there they come across the site of an elephant killing and are involved in the subsequent apprehension of one of the poachers.
The poachers come from South Africa and are after ivory for a buyer who is using what they all assume to be a fictitious name.
