The Four Musketeers defeat the Gargoyles, and manage to apprehend the man controlling them, but Durand releases him and they both escape. Robin follows Durand, while D'Eon and Teillagory follow the man back to his masters. They find out that Caron, the man they were pursuing, works for Comte de Saint-Germain, who sets the house on fire to aid their escape after realizing that D'Eon and Teillagory are eavesdropping. D'Eon forces his way into the house and discovers a book that he believes to be important. D'Eon and his companions meet Durand at Lia's casket at his request. King Louis XV and Duc d'Broglie then invite D'Eon to follow in his sister's footsteps and join Le Secret du Roi.
