From the Blurb:
When a Kalahari ranger is found dead in a dry ravine, his corpse surrounded by three Bushmen, the local police arrest the nomads. Botswana's Detective 'Kubu' Bengu investigates the case and is reunited with his old school friend Khumanego, a Bushman and advocate for his people. Khumanego claims the nomads are innocent and the arrests motivated by racist antagonism. The Bushmen are released but, soon after, another man is murdered in similar circumstances. Are the Bushmen to blame, or is it a copycat murder?
