Lulu Sawyer, the heroine of Diane Johnson’s captivating new novel, arrives in Marrakech, Morocco, hoping to rekindle her romance with a worldly Englishman, Ian Drumm. It’s the perfect cover for her assignment with the American CIA: tracing the flow of money from well-heeled donors to radical Islamic groups. While spending her days poolside among Europeans, in villas staffed by local maids in abayas, and her nights at lively dinner parties, Lulu observes the fragile coexistence of two cultures which, if not yet clashing, have begun to show signs of fracture. Beneath the surface of this polite expatriate community lies a more sinister world laced not only with double standards, but with double agents.
