Elena Franchi, a fifty-year-old art history teacher, quits her teaching job at a school in Bologna and moves to Nice where she opens a cleaning agency. Together with Karim, a thirty-eight-year-old Tunisian without residency papers and her sole trusted assistant, she runs into trouble when one of her guests, Cyril Weston, the young descendant of an upper-class family gives her five thousand euros to replace the wine-stained carpet in the family’s luxury apartment in Place Garibaldi in Nice. Unexpected events and often exhilarating mishaps occur until Elena and Karim, with the decisive help of Didier Ratagne, discover the disturbing truth.
