Of Wheels and Witches

Jeffery Davidson, a schoolboy from Johannesburg, goes to spend the school holidays at a farm. There he meets Catherine, an orphan from England, Janet, a rich white farmer's daughter, and Sipho, a poor black peasant's grandson. They have fun riding horses and exploring caves, until they encounter an ominous symbol of a wheel, and through a witch they learn of a plot to harm Sipho's father. In trying to find a way to warn him of the danger, they find themselves up against the power of the apartheid state, and they themselves are in danger.
