Based on another snatch of du Maurier family history, this reaches back to the time of the French Revolution. Told through a principal in the drama, Sophie Duval, the tale concerns an errant brother and his English born son. The plot is spread thin, but the setting is as lively as the original must have been— the French countryside under the Terror and the fascinating glass industry. The author's name will sell a book that may well be below her peak as a storyteller.
