Paul Theroux sets off for Cape Town from Cairo -- the hard way. Travelling across bush and desert, down rivers and across lakes, and through country after country, Theroux visits some of the most beautiful landscapes on earth, and some of the most dangerous. It is a journey of discovery and of rediscovery -- of the unknown and the unexpected, but also of people and places he knew as a young and optimistic teacher forty years before. Safari in Swahili simply means "journey", and this is the ultimate safari. It is Theroux in his element -- a trip where chance encounter is everything, where departure and arrival times are an irrelevance, and where contentment can be found balancing on the top of a truck in the middle of nowhere.
