This is the only role in this episode. The role is a monologue taking the shape of several journal entries. Nicolas-Jean Moreau is a Parisian day laborer who is working to move overflowing corpses into the quarries under Paris. That said, the character reading these entries aloud is not necessarily him so this role is open to everyone. Feel free to act in any accent that you can do convincingly without caricature, bonus points if its French.  There are only two or three lines in french, one of which is listed.
