Baraba is sent to accompany a German family of missionaries to Africa. He poses as their student, but in reality he has been sent by Lady Ada Lovelace in order to investigate the possibility of the dis-souled near the famed mountain of Kilimanjaro. Accompanying Mr and Mrs Rebmann, and their cousin Clare, he is there when a strange Englishman shows up, in his range rover. Bernard Bourne has been living in Africa for some time, and so can provide them with some much needed supplies. He brings Clare to his home in order to pick up some of these supplies, along with the servant Baraba. But Bourne is not as altruistic as he may seem.
