The Cooper Clan has passed down its collected theft techniques through generations in a family heirloom called the Thievius Raccoonus—a book recording every secret move the clan ever developed. On Sly Cooper's eighth birthday, it was supposed to pass to him. Instead, a gang called the Fiendish Five, led by Clockwerk, the Cooper family's ancient nemesis, attacked the household, killed Sly's parents, and took every page of the book. Sly was sent to an orphanage, where he met Bentley—a brilliant hacker and tactician—and Murray, the group's getaway driver and muscle. They left together at sixteen. Years later, the Cooper Gang breaks into an Interpol headquarters in Paris to steal a file on the Fiendish Five. Inspector Carmelita Fox nearly stops them. She doesn't. With the file in hand, Sly finally knows where to find the people who destroyed his family.
