A retelling of the glamorous life of Arsène Lupin, the celebrated jewel thief of belle époque Europe. Tired of boring rural life at the family’s luxurious castle in Normandy, Arsène's father instructs him to steal a particularly necklace once worn by Marie Antoinette. Once the necklace is passed off to his father, Arsène goes to sleep, only to wake the next morning to discover his father dead and the family cast out. Still on the run from the law as an adult, Arsène returns to his childhood home and, with a false name, takes a job as the Duke’s martial arts teacher. One night, though, he spies on a gathering of Royalist plotters as they condemn to death the Countess of Cagliostro. Lupin saves her and thus begins their intertwining fates. Decades fly by and historical events whirl around them as their mutual dependency--sometimes as lovers, sometimes as enemies--deepens.
