In the 18th and 19th centuries, British colonialists who adopted traditional Indian lifestyles and took Indian women as their brides were known as "white mughals." Dalrymple writes of James Kirkpatrick, officer of the British East India Company, convert to Islam and husband to an Indian princess. In doing so, he vividly portrays the "white mughal" experience and its influence on the history of India and England. Dalrymple has written engagingly about India in a series of essays and travel books, including the outstanding "City of Djinns," a memoir of a year in Delhi.  (IDA233, $20.00)
