I loved Paris, a city with secrets. Like book covers, some leather, some cloth, each Parisian door led to an unexpected world. A courtyard could contain a knot of bicycles or a plump concierge armed with a broom. In the case of the Library, the massive wooden door opened to a secret garden. Bordered by petunias on one side, lawn on the other, the white pebbled path led to the brick-and-stone mansion.
