Natural World (1983) : 29x4

In the small African kingdom of Swaziland, the black mamba is a snake both feared and revered. During summer, these elegant yet lethal snakes turn up everywhere - in homes, schools and cars - and people are bitten every week. Enter Thea Litschka-Koen, a mum and hotel manager who has become known affectionately as the white witch. She and her husband are on call 24 hours a day to rescue and release black mambas when they get too close for comfort. But what everyone wants to know is will they come back again? We follow Thea and her team as they set up a pioneering new scientific project: to track the black mambas they release back into the wild, and find out just how these deadly snakes spend their lives.
