This has a new theme and new setting, in that the period is that following the French Revolution, when Bonaparte was gaining power, and when some of the exiles were creeping back, incognito. A Salem sea captain and the foundling child he had adopted, and who is now nearly grown up, go to France to try to trace the noble grandparents that Josephine de Beauharnais had identified for her. She is instrumental in bringing about the meeting of Napoleon and Josephine -- and they in turn aid in her search, and insure its successful termination. The Chateau of the Swan comes back into its owner's hands, and Sally divides her time between her American and her French families. It is good historical background material, and a good story with mystery and adventure and romance well blended.
