When Mary joins the Peace Corps the shah reigns in Iran and John F. Kennedy has left his mark on the world. Sent to Kerman, a conservative city on the Iranian plateau, she teaches English to high school girls. In the classroom, or walking through the bazaar amid turbaned Baluchi tribesmen and chanting Sufi dervishes, she is the exotic one. The adobe walls that seclude women exclude her, a bareheaded foreigner. Woven throughout are dusty travels from the Persian Gulf to the Caspian Sea, colorful feasts, rich history and hidden romance. Walled In, Walled Out recounts her convoluted, often humorous journey from ignorance to understanding in a country where the people speak with many voices.
