Assisted by a French cryptographer and government agent named Sophie, Langdon is challenged to decipher a chain of cryptic codes and puzzles, all the while trying to stay ahead of Fache's lawmen in a chase through the Louvre, out into the Parisian cityscape, and finally across the channel to England.
