Hot Water Man by Deborah Moggach
Fresh from London, Christine and Donald Manley have come to the alien swelter of Karachi- Christine to conceive a cgild, Donald to sell the Pill for a pharmaceutical company. Among the ex-pats already there is straight-talking Duke Hanson, whose all-American values cannot prevent him falling, then sinking, hopelessly in love with a sophisticated Pakistani girl. In the ensuing tangle of Anglo-American-Oriental relations, the strangest things for those who have come out East are revealed in the very people with whom they arrived. . .
