"Two men fight to save the Oasis of Saraifa from the relentless, encroaching sands of the Empty Quarter. Colonel Whitaker is a bearded Englishman turned Moslem, a legendary desert figure known to the Arabs as "The Wise One"; his natural son David is a tough from the Cardiff docks who is wanted by the police and who escapes to Arabia to become a geologist. Welsh solicitor George Aubrey Grant, whose duties as executor, take him to the Persian Gulf where he sets out to reunite the two men. But, the disappearance and alleged death of David, finds Grant caught up in the intrigues of the big oil companies and the wars of the oil-mad Sheiks."--Publisher description.
