The Jefferson Puzzle, also known as the Cahill Fire Painting, is a picture of the Cahill Fire and is obtainable via the cards in the books. Each book has a Jefferson Puzzle Piece on the back of one of the cards and when all ten cards from all ten books are arranged in the correct order they make a picture of the Cahill Fire .
At the bottom of the Sakhet in the bushes there is a signed name spelled Kylob. Other than that it is believed that Fiske Cahill made it because of the initials on one puzzle piece.
The name of the Jefferson Puzzle was coined by the fact that the first piece of the puzzle from 'The Maze of Bones' has a front of the plan of the Jefferson Memorial. Thus the puzzle earned the nickname the 'Jefferson Puzzle.'
