Daisy is a teen who gets sent to live with her aunt in Paris, France. The aunt gives Daisy quite a bit of freedom to go off on her own and doesn't seem to get too worried about things that happen (like Daisy falling off a roof--though the aunt doesn't know this until much later--but you'd think when Daisy showed up with ripped clothes and injured, that the aunt would ask more questions than she does.)

Somehow Daisy and her aunt become enmeshed in a plot revolving around a historic diamond necklace. ( )
