Sophie is a little girl, naiver than nasty; sometimes abetted by her cousin Paul, she always gets into mischief, although the boy is much wiser than she is. Her best friends , Camille and Madeleine are so virtuous that Sophie's behavior doesn't compare favorably with theirs. In the castle where she lives with a rather severe mother (and a father very often gone to Paris), not a day goes by without she getting up to mischief.
