The Parisienne cyber-sleuth's adventures take her to areas of Paris unknown to most readers, off the tourist track and yet often in close proximity to well-known buildings such as the Louvre Museum or Gare du Nord.
We first meet her in Paris during the mid-1990s, where having attended the famous Sorbonne University as a pre-med student, she decided that medicine was not her forte and chose instead to take over her father's "Leduc Detective" agency after his death during a stakeout operation.
Described by Booklist as "a delightfully unbuttoned Audrey Hepburn for the twenty-first century”, Leduc is a sharp, fashionable, and quite headstrong young woman who has assumed the investigative mantle left to her by her father.
Wearing Chanel outfits acquired at second-hand shops and living in a drafty 19th-century apartment with her dog Miles Davis, Leduc's bohemian lifestyle can be compared with that of Sherlock Holmes.
Her godfather Commissaire Morbier was her father's police partner, and he sometimes reluctantly helps her on cases by leaking information to her or applying official leverage.
