All human wisdom

Summary: In 1927, the great and the good of Paris gather at the funeral of the wealthy banker, Marcel Pericourt. His daughter, Madeleine, is poised to take over his financial empire (although, unfortunately, she knows next to nothing about banking). More unfortunately still, when Madeleine's seven-year-old son, Paul, tumbles from a second floor window of the Pericourt mansion on the day of his grandfather's funeral, and suffers life-changing injuries, his fall sets off a chain of events that will reduce Madeleine to destitution and ruin in a matter of months. Using all her reserves of ingenuity, resourcefulness, and a burning desire for retribution, Madeleine sets about rebuilding her life. She will be helped by an ex-Communist fixer, a Polish nurse who doesn't speak a word of French, a brainless petty criminal with a talent for sabotage, an exiled German Jewish chemist, a very expensive forger, an opera singer with a handy flair for theatrics, and her own son with ideas for a creative new business to take Paris by storm.
