The Thievius Raccoonus is an ancient tome handed down from parent to child throughout the centuries that acts as both a handbook describing many of the skills of the Cooper Clan, and a record of accomplishments and events, such as heists, that involved or affected the members of the Clan. The current holder of the Thievius Raccoonus is Bentley, as Sly Cooper (the rightful owner) is trapped in Egypt sometime in the past.
