Mining diamonds is a lucrative business, but it soon proves itself deadly. Shortly after Kubu joins the CID, the richest diamond mine in the world is robbed of 100,000 carats of diamonds in transit. The robbery is well-executed and brutal. Police immediately suspect an inside job, but there is no evidence of who it could be. When the robbers are killed execution-style in South Africa and the diamonds are still missing, the game changes, and suspicion focuses on a witch doctor and his son. Does Kubu have the skill and the integrity to engineer an international trap and catch those responsible, or will the biggest risk of his life end in disaster?
