12. Necklace

When diamond courier David Ramsey is found burned to death with his hands barb-wired behind his back and a tire around his body, Oosterhuis realises that he is killed in a traditional South African style, and he and Pogue wonder if someone was trying to send a message. Weeks and Gillam investigate the death of a small child who shows a history of physical abuse when their medical examiner tells them that he disagrees with the coroner's report that the mother caused the child's death, especially considering the child wasn't even with the mother when the fatal blow was struck.
