Seven centuries on, Tim Mackintosh-Smith's passionate pursuit of the fourteenth-century traveller takes him to landfalls in remote tropical islands, torrid Indian Ocean ports and dusty towns on the shores of the Saharan sand-sea. His zigzag itinerary across time and space leads from Zanzibar to the Alhambra (via the Maldives, Sri Lanka, China, Mauritania and Guinea) and to a climactic conclusion to his quest for the man he calls 'IB' - a man who out-travelled Marco Polo by a factor of three, who spent his days with saints and sultans and his nights with an intercontinental string of slave-concubines.
Tim's journey is a search for survivals from IB's world - material, human, spiritual, edible - however, when your fellow traveller has a 700-year head start, familiar notions don't always work.
